In recent years many developments were done to investigate different appropriate materials for these electrodes. One of these materials is the electrical conductive polymer poly(3,4-ethylenedioxythiophene) (PEDOT), which has lower impedance and higher charge injection capacity compared to noble metals like gold and platinum. However the long-term stability of this polymer is still unclear. Thus this paper reports on the in-vitro evaluation of the long-term stability of PEDOT coated gold microelectrodes. For this purpose a highly flexible electrocorticography (ECoG) electrode array, based on the polymer polyimide, is used. This array consists of circular gold electrodes with a diameter of 560 µm (0.25 mm2). In total 25 electrodes of this array were coated simultaneously with the polymer PEDOT:PSS in a cleanroom environment using a galvanostatic electropolymerization process. After the coating the array is additionally sterilized using a steam sterilization process (121°C, 1 bar, 20.5 min) to simulate autoclaving prior to the implantation of such an electrode array. The long-term measurements were performed in phosphate-buffered saline solution (PBS, pH 7.4) at the constant body temperature of 37°C. For the in-vitro electrical stimulation a one channel bipolar current stimulator is used. The stimulation protocol consists of a bipolar current amplitude of 5 mA (cathodal phase first), a pulse duration of 100 µs per phase, a pulse pause of 50 µs and a frequency of 1 kHz. A PEDOT:PSS coated gold electrode with an area of 1 cm2 serves as the counter electrode. The electrical stimulation is performed continuously with a total amount of 86.4 million bipolar current pulses per day. The condition of the PEDOT coated electrodes is monitored in between with electrical impedance spectroscopy measurements. The results of this study demonstrate that the PEDOT coated electrodes are stable for more than 3.6 billion bipolar current pulses. Also the unstimulated electrodes show currently no degradation after the time period of 5 months. These results indicate an appropriate long-term stability of this electrode coating for chronic recording and electrical stimulation. The long-term measurements are still continuing to investigate the life limit of this electrode coating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20recording" title="chronic recording">chronic recording</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20stability" title=" long-term stability"> long-term stability</a>, <a href="https://publications.waset.org/abstracts/search?q=microelectrodes" title=" microelectrodes"> microelectrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDOT" title=" PEDOT"> PEDOT</a> </p> <a href="https://publications.waset.org/abstracts/38433/in-vitro-evaluation-of-the-long-term-stability-of-pedotpss-coated-microelectrodes-for-chronic-recording-and-electrical-stimulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38433.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">585</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1923</span> Exploring the Potential of PVDF/CCB Composites Filaments as Potential Materials in Energy Harvesting Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fawad%20Ali">Fawad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Albakri"> Mohammad Albakri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing demand for advanced multifunctional materials has led to significant research in polymer composites, particularly polyvinylidene fluoride (PVDF) and conducting carbon black (CCB) composites.

Rustighi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Elastomeric dielectric material has recently become a new alternative for actuator technology. The characteristics of dielectric elastomers placed between two electrodes to withstand large strain when electrodes are charged has attracted the attention of many researcher to study this material for actuator technology. Thus, in the past few years Danfoss Ventures A/S has established their own dielectric electro-active polymer (DEAP), which was called PolyPower. The main objective of this work was to investigate the dynamic characteristics for vibration control of a PolyPower actuator folded in ‘pull’ configuration. A range of experiments was carried out on the folded actuator including passive (without electrical load) and active (with electrical load) testing. For both categories static and dynamic testing have been done to determine the behavior of folded DEAP actuator. Voltage-Strain experiments show that the DEAP folded actuator is a non-linear system. It is also shown that the voltage supplied has no effect on the natural frequency. Finally, varying AC voltage with different amplitude and frequency shows the parameters that influence the performance of DEAP folded actuator. As a result, the actuator performance dominated by the frequency dependence of the elastic response and was less influenced by dielectric properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dielectric%20electro-active%20polymer" title="dielectric electro-active polymer">dielectric electro-active polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=pull%20actuator" title=" pull actuator"> pull actuator</a>, <a href="https://publications.waset.org/abstracts/search?q=static" title=" static"> static</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic" title=" dynamic"> dynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=electromechanical" title=" electromechanical"> electromechanical</a> </p> <a href="https://publications.waset.org/abstracts/26387/dynamics-characterizations-of-dielectric-electro-active-polymer-pull-actuator-for-vibration-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26387.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1920</span> Anodic Stability of Li₆PS₅Cl/PEO Composite Polymer Electrolytes for All-Solid-State Lithium Batteries: A First-Principles Molecular Dynamics Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hao-Wen%20Chang">Hao-Wen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Santhanamoorthi%20Nachimuthu"> Santhanamoorthi Nachimuthu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyh-Chiang%20Jiang"> Jyh-Chiang Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All-solid-state lithium batteries (ASSLBs) are increasingly recognized as a safer and more reliable alternative to conventional lithium-ion batteries due to their non-flammable nature and enhanced safety performance. ASSLBs utilize a range of solid-state electrolytes, including solid polymer electrolytes (SPEs), inorganic solid electrolytes (ISEs), and composite polymer electrolytes (CPEs). SPEs are particularly valued for their flexibility, ease of processing, and excellent interfacial compatibility with electrodes, though their ionic conductivity remains a significant limitation. ISEs, on the other hand, provide high ionic conductivity, broad electrochemical windows, and strong mechanical properties but often face poor interfacial contact with electrodes, impeding performance. CPEs, which merge the strengths of SPEs and ISEs, represent a compelling solution for next-generation ASSLBs by addressing both electrochemical and mechanical challenges. Despite their potential, the mechanisms governing lithium-ion transport within these systems remain insufficiently understood. In this study, we designed CPEs based on argyrodite-type Li₆PS₅Cl (LPSC) combined with two distinct polymer matrices: poly(ethylene oxide) (PEO) with 24.5 wt% lithium bis(trifluoromethane)sulfonimide (LiTFSI) and polycaprolactone (PCL) with 25.7 wt% LiTFSI. Through density functional theory (DFT) calculations, we investigated the interfacial chemistry of these materials, revealing critical insights into their stability and interactions. Additionally, ab initio molecular dynamics (AIMD) simulations of lithium electrodes interfaced with LPSC layers containing polymers and LiTFSI demonstrated that the polymer matrix significantly mitigates LPSC decomposition, compared to systems with only a lithium electrode and LPSC layers. These findings underscore the pivotal role of CPEs in improving the performance and longevity of ASSLBs, offering a promising path forward for next-generation energy storage technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=all-solid-state%20lithium-ion%20batteries" title="all-solid-state lithium-ion batteries">all-solid-state lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20solid%20electrolytes" title=" composite solid electrolytes"> composite solid electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT%20calculations" title=" DFT calculations"> DFT calculations</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-ion%20transport" title=" Li-ion transport"> Li-ion transport</a> </p> <a href="https://publications.waset.org/abstracts/192118/anodic-stability-of-li6ps5clpeo-composite-polymer-electrolytes-for-all-solid-state-lithium-batteries-a-first-principles-molecular-dynamics-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192118.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">20</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1919</span> Porous Ni Electrodes Modified with Au Nanoparticles for Hydrogen Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20P%C3%A9rez-Herranz">V.

The supporting macroporous Ni electrodes have been obtained by means of the electrodeposition at high current densities. Then, the Au nanoparticles were synthesized and added to the electrode surface. The electrocatalytic behaviour of the developed electrocatalysts was studied by means of pseudo-steady-state polarization curves, electrochemical impedance spectroscopy (EIS) and hydrogen discharge curves. The size of the Au synthetized nanoparticles shows a monomodal distribution, with a very sharp band between 10 and 50 nm. The characteristic parameters d10, d50 and d90 were 14, 20 and 31 nm respectively. From Tafel polarization data has been concluded that the Au nanoparticles improve the catalytic activity of the developed electrodes towards the HER respect to the macroporous Ni electrodes. EIS permits to obtain the electrochemically active area by means of the roughness factor value. All the developed electrodes show roughness factor values in the same order of magnitude. From the activation energy results it can be concluded that the Au nanoparticles improve the intrinsic catalytic activity of the macroporous Ni electrodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Au%20nano%20particles" title="Au nano particles">Au nano particles</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20evolution%20reaction" title=" hydrogen evolution reaction"> hydrogen evolution reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20Ni%20electrodes" title=" porous Ni electrodes"> porous Ni electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20impedance%20spectroscopy" title=" electrochemical impedance spectroscopy "> electrochemical impedance spectroscopy </a> </p> <a href="https://publications.waset.org/abstracts/27355/porous-ni-electrodes-modified-with-au-nanoparticles-for-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">622</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1918</span> Study on the Voltage Induced Wrinkling of Elastomer with Different Electrode Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhende%20Hou">Zhende Hou</a>, <a href="https://publications.waset.org/abstracts/search?q=Fan%20Yang"> Fan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Guoli%20Zhang"> Guoli Zhang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dielectric elastomer is a promising class of Electroactive polymers which can deform in response to an applied electric field. Comparing general smart material, the Dielectric elastomer is more compliance and can achieve higher energy density, which can be for diverse applications such as actuators, artificial muscles, soft robotics, and energy harvesters. The coupling of the Electroactive polymers and the electric field is that the elastomer is sandwiched between two compliant electrodes and when the electrodes are subjected to a voltage, the positive and negative charges on the two electrodes compress the polymer, so that the polymer reduces in thickness and expands in area. However, the pre-stretched dielectric elastomer film not only can achieve large electric-field induced deformation but also is prone to wrinkling, under the interaction of its own strain energy and the applied electric field energy. For a uniaxially pre-stretched dielectric elastomer film, the electrode area is an important parameter to the electric-field induced deformation and may also be a key factor affecting the film wrinkling. To determine and quantify the effect experimentally, VHB 9473 tapes were employed and compliant electrodes with different areas were pant on each of them. The tape was first tensed to a uniaxial stretch of 8. Then a DC voltage was applied to the electrodes and increased gradually until wrinkling occurred in the film. Then, the critical wrinkling voltages of the film with different electrode areas were obtained, and the wrinkle wavelengths were obtained simultaneously for analyzing the wrinkling characteristics. Experimental results indicate when the electrode area is smaller the wrinkling voltage is higher, and with the increases of electrode area, the wrinkling voltage decreases rapidly until a specific area. Beyond that, the wrinkling voltage becomes larger gradually with the increases of the area. While the wrinkle wavelength decreases gradually with the increase of voltage monotonically. That is, the relation between the critical wrinkling voltage and the electrode areas is U-shaped. Analysis believes that the film wrinkling is a kind of local effect, the interaction and the energy transfer between electrode region and non-electrode region have great influence on wrinkling. In the experiment, very thin copper wires are used as the electrode leads that just contact with the electrodes, which can avoid the stiffness of the leads affecting the wrinkling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastomers" title="elastomers">elastomers</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial%20stretch" title=" uniaxial stretch"> uniaxial stretch</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode%20area" title=" electrode area"> electrode area</a>, <a href="https://publications.waset.org/abstracts/search?q=wrinkling" title=" wrinkling"> wrinkling</a> </p> <a href="https://publications.waset.org/abstracts/93758/study-on-the-voltage-induced-wrinkling-of-elastomer-with-different-electrode-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93758.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1917</span> Effect of Electrodes Spacing on Energy Consumption of Electrocoagulation Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20S.%20Hashim">Khalid S.

Hence, optimizing these key operating parameters is considered a vital step to remove a pollutant efficiently. In this context, the present study has been carried out to explore the influence of electrodes spacing on energy consumption, temperature of the water being treated, and iron removal from water. To achieve this target, iron containing synthetic water samples were electrolysed for 20 min, using a new flow column electrocoagulation reactor (FCER), at three different gaps between electrodes (5, 10, and 20 mm). These batch experiments were commenced at a constant current density of 1.5 mA/cm² and initial pH of 6. The obtained results demonstrated that increasing gap between electrodes negatively influenced the performance of the EC method. It was found that increasing the gap between electrodes from 5 to 20 mm increased the energy consumption from about 3.3 to 7.3 kW.h/m³, and water temperature from 20.2 to 22 °C, respectively. In addition, it has been found, after 20 min of electrolysing, that increasing the gap between electrodes from 5 to 20 mm increased the residual iron concentration from 0.05 to 1.01 mg/L, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title="electrocoagulation">electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodes" title=" electrodes"> electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=iron" title=" iron"> iron</a> </p> <a href="https://publications.waset.org/abstracts/72173/effect-of-electrodes-spacing-on-energy-consumption-of-electrocoagulation-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72173.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1916</span> Characterization of Graphene Oxide Coated Gold Electrodes for Bioimpedance Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20G%C3%BClden%20%C5%9Ei%CC%87m%C5%9Fek">Fatma Gülden Şi̇mşek</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20Meli%CC%87h%20Can"> Osman Meli̇h Can</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Yumak"> Mehmet Yumak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bora%20Gari%CC%87pcan"> Bora Gari̇pcan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yekta%20%C3%9Clgen"> Yekta Ülgen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the impedance spectroscopy is used as a detection tool in order to characterize surface coating with graphene oxide.

Enculescu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among the numerous methods for obtaining polymer nanofibers, the electrospinning technique distinguishes itself due to the more growing interest induced by its proved utility leading to developing and improving of the method and the appearance of novel materials. In particular, production of polymeric nanofibers in which different dopants are introduced was intensively studied in the last years because of the increased interest for the obtaining of functional electrospun nanofibers. Electrospinning is a facile method of obtaining polymer nanofibers with diameters from tens of nanometers to micrometrical sizes that are cheap, flexible, scalable, functional and biocompatible. Besides the multiple applications in medicine, polymeric nanofibers obtained by electrospinning permit manipulation of light at nanometric dimensions when doped with organic dyes or different nanoparticles. It is a simple technique that uses an electrical field to draw fine polymer nanofibers from solutions and does not require complicated devices or high temperatures. Different morphologies of the electrospun nanofibers can be obtained for the same polymeric host when different parameters of the electrospinning process are used. Consequently, we can obtain tuneable optical properties of the electrospun nanofibers (e.g. changing the wavelength of the emission peak) by varying the parameters of the fabrication method. We focus on obtaining doped polymer nanofibers with enhanced optical properties using the electrospinning technique. The aim of the paper is to produce dye-doped polymer nanofibers’ mats incorporating uniformly dispersed dyes. Transmission and fluorescence of the fibers will be evaluated by spectroscopy methods. The morphological properties of the electrospun dye-doped polymer fibers will be evaluated using scanning electron microscopy (SEM). We will tailor the luminescent properties of the material by doping the polymer (polyvinylpyrrolidone or polymethylmetacrilate) with different dyes (coumarins, rhodamines and sulforhodamines). The tailoring will be made taking into consideration the possibility of changing the luminescent properties of electrospun polymeric nanofibers that are doped with different dyes by using different parameters for the electrospinning technique (electric voltage, distance between electrodes, flow rate of the solution, etc.). Furthermore, we can evaluated the influence of the concentration of the dyes on the emissive properties of dye-doped polymer nanofibers using different concentrations. The advantages offered by the electrospinning technique when producing polymeric fibers are given by the simplicity of the method, the tunability of the morphology allowed by the possibility of controlling all the process parameters (temperature, viscosity of polymeric solution, applied voltage, distance between electrodes, etc.), and by the absence of necessity of using harsh and supplementary chemicals such as the ones used in the traditional nanofabrication techniques.

Premodulated IFC and ‘true’ IFC at beat frequencies of 4, 40 and 90Hz were applied via four electrodes to the distal medial thigh of 15 healthy subjects. The current was measured via three Teflon coated fine needle electrodes that were inserted into the superficial layer of skin, then into the subcutaneous tissue (≈1 cm deep) and then into muscle tissue (≈2 cm deep). The needle electrodes were placed in the middle of the four IFC electrodes, between two channels and outside the four electrodes. Readings were taken at each tissue depth from each electrode during each treatment frequency then digitized and stored for analysis. All voltages were greater at all depths and locations than baseline (p < 0.01) and voltages decreased with depth (P=0.039). Lower voltages of all currents were recorded in the middle of the four electrodes with the highest voltage being recorded outside the four electrodes in all depths (P=0.000).For each frequency of ‘true’ IFC, the voltage was higher in the superficial layer outside the electrodes (P ≤ 0.01).Premodulated had higher voltages along the line of one circuit (P ≤ 0.01). Clinically, IFC appears to pass through skin layers to depth and is more efficient than premodulated IFC when targeting muscle tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrotherapy" title="electrotherapy">electrotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=interferential%20current" title=" interferential current"> interferential current</a>, <a href="https://publications.waset.org/abstracts/search?q=interferential%20therapy" title=" interferential therapy"> interferential therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20frequency%20current" title=" medium frequency current"> medium frequency current</a> </p> <a href="https://publications.waset.org/abstracts/20986/depth-of-penetration-and-nature-of-interferential-current-in-cutaneous-subcutaneous-and-muscle-tissues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20986.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1913</span> Studying the Bond Strength of Geo-Polymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rama%20Seshu%20Doguparti">Rama Seshu Doguparti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the experimental investigation on the bond behavior of geo polymer concrete.

Since the electric signal needs electrodes to be transmitted to an organism, electrodes play an important role of stimulations. The materials of stimulation electrodes affect the efficiency of the delivered currents. The higher the efficiency of the electrodes, the lower the threshold current can be used to stimulate the organism which minimizes the potential damages to the adjacent tissues. In this study, we proposed a biocompatible composite electrode composed of high-charge-capacity iridium oxide (IrOₓ) film for a bone-guide extra-cochlear implant. IrOₓ was exploited to decrease the threshold current due to its high capacitance and low impedance. The IrOₓ electrode was fabricated via microelectromechanical systems (MEMS) photolithography and examined with in-vivo tests with guinea pigs. Based on the measured responses of brain waves to sound, the results demonstrated that IrOₓ electrodes have a lower threshold current compared with the Platinum (Pt) electrodes. The research results are expected to be beneficial for implantable and biocompatible electrodes for electrical stimulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implants" title="cochlear implants">cochlear implants</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=iridium%20oxide" title=" iridium oxide"> iridium oxide</a> </p> <a href="https://publications.waset.org/abstracts/100114/developing-biocompatible-iridium-oxide-electrodes-for-bone-guided-extra-cochlear-implant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100114.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1909</span> Improving Carbon Fiber Structural Battery Performance with Polymer Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kathleen%20Moyer">Kathleen Moyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Nora%20Ait%20Boucherbil"> Nora Ait Boucherbil</a>, <a href="https://publications.waset.org/abstracts/search?q=Murtaza%20Zohair"> Murtaza Zohair</a>, <a href="https://publications.waset.org/abstracts/search?q=Janna%20Eaves-Rathert"> Janna Eaves-Rathert</a>, <a href="https://publications.waset.org/abstracts/search?q=Cary%20Pint"> Cary Pint</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study demonstrates the significance of interface engineering in the field of structural energy by being the first case where the performance of the system with the structural battery is greater than the performance of the same system with a battery separate from the system. The benefits of improving the interface in the structural battery were tested by creating carbon fiber composite batteries (and independent graphite electrodes and lithium iron phosphate electrodes) with and without an improved interface. Mechanical data on the structural batteries were collected using tensile tests and electrochemical data was collected using scanning electron microscopy equipment. The full-cell lithium-ion structural batteries had capacity retention of over 80% exceeding 100 cycles with an average energy density of 52 W h kg−1 and a maximum energy density of 58 W h kg−1. Most scientific developments in the field of structural energy have been done with supercapacitors. Most scientific developments with structural batteries have been done where batteries are simply incorporated into the structural element. That method has limited advantages and can create mechanical disadvantages. This study aims to show that a large improvement in structure energy research can be made by improving the interface between the structural device and the battery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title="composite materials">composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20performance" title=" electrochemical performance"> electrochemical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20interface" title=" polymer interface"> polymer interface</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20batteries" title=" structural batteries"> structural batteries</a> </p> <a href="https://publications.waset.org/abstracts/153279/improving-carbon-fiber-structural-battery-performance-with-polymer-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1908</span> Effects of Array Electrode Placement on Identifying Localised Muscle Fatigue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20R.%20Al-Mulla">Mohamed R.

Trials were conducted on four healthy males, with sEMG signal acquisition from fatiguing isometric contractions. The signal was analysed using the power spectrum density. The separation between the two classes of fatigue (non-fatigue and fatigue) was calculated using the Davies-Bouldin Index (DBI).

Microstructural characterization, as one of the main materials development tools, plays a pivotal role in the production of better clean energy devices. In this study, methods for characterization and studying of the defects and components distribution were performed on the polymer electrolyte membrane fuel cell (PEMFC) and Li-ion battery (LIB) electrodes in 2D and 3D. The particles distribution, porosity, mechanical defects, and component distribution were studied by Scanning Electron Microscope (SEM), SEM-Focused Ion Beam (SEM-FIB), and Scanning Transmission Electron Microscope equipped with Energy Dispersive Spectroscopy (STEM-EDS). The 3D results obtained from X-ray Computed Tomography (XCT) revealed the pathways for electron and ion conductivity and defects progression maps. Computer-aided methods (Avizo) were employed to simulate the properties and performance of the microstructure in the electrodes.

In this work we have investigated the effect of nanofibers on the electrical properties of PVDF-HFP based gel electrolytes. The nanocomposites polymer electrolytes have been synthesized by solution casting technique with 10wt% of ZrO2. By analysis of impedance spectroscopy it has been demonstrated that the incorporation of ZrO2 into PVDF-HFP–(PC+DEC)–LiClO4 gel polymer electrolyte system significantly enhances the ionic conductivity of the electrolyte. The enhancement of ionic conductivity seems to be correlated with the fact that the dispersion of ZrO2 to PVDF-HFP prevents polymer chain reorganization due to the high aspect ratio of ZrO2, resulting in reduction in polymer crystallinity, which gives rise to an increase in ionic conductivity. The decrease of crystallinity of PVDF-HFP due the addition of ZrO2 has been confirmed by XRD. The interaction of ZrO2 with various constituents of polymer electrolytes has been studied by FTIR spectroscopy. TEM results show that the fillers (ZrO2) has distributed uniformly in the polymer electrolytes. Moreover, ZrO2 added gel polymer electrolytes offer better thermal stability as compared to that of ZrO2 free electrolytes as confirmed by TGA analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20electrolytes" title="polymer electrolytes">polymer electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=ZrO2" title=" ZrO2"> ZrO2</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20conductivity" title=" ionic conductivity"> ionic conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a> </p> <a href="https://publications.waset.org/abstracts/21340/pvdf-hfp-based-nanocomposite-gel-polymer-electrolytes-dispersed-with-zro2-for-li-ion-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21340.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">474</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1904</span> Hydrogen Production Using Solar Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20M.%20Sakr">I.

Two methods are used and compared for separation between the cathode and anode, which are acrylic separator and polymeric membrane.

It is found that the rate of hydrogen production increases using the polymeric membrane installed between the electrodes. The experimental results show also that, the performance of alkaline water electrolysis unit is dominated by the electrolyte concentration and the gap between the electrodes. Smaller gaps between the pair of electrodes are demonstrated to produce higher rates of hydrogen with higher system efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20production" title="hydrogen production">hydrogen production</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20electrolysis" title=" water electrolysis"> water electrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a> </p> <a href="https://publications.waset.org/abstracts/62050/hydrogen-production-using-solar-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62050.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1903</span> Single-Molecule Analysis of Structure and Dynamics in Polymer Materials by Super-Resolution Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroyuki%20Aoki">Hiroyuki Aoki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The physical properties of polymer materials are dependent on the conformation and molecular motion of a polymer chain. Therefore, the structure and dynamic behavior of the single polymer chain have been the most important concerns in the field of polymer physics. However, it has been impossible to directly observe the conformation of the single polymer chain in a bulk medium. In the current work, the novel techniques to study the conformation and dynamics of a single polymer chain are proposed. Since a fluorescence method is extremely sensitive, the fluorescence microscopy enables the direct detection of a single molecule. However, the structure of the polymer chain as large as 100 nm cannot be resolved by conventional fluorescence methods because of the diffraction limit of light. In order to observe the single chains, we developed the labeling method of polymer materials with a photo-switchable dye and the super-resolution microscopy. The real-space conformational analysis of single polymer chains with the spatial resolution of 15-20 nm was achieved. The super-resolution microscopy enables us to obtain the three-dimensional coordinates; therefore, we succeeded the conformational analysis in three dimensions. The direct observation by the nanometric optical microscopy would reveal the detailed information on the molecular processes in the various polymer systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20materials" title="polymer materials">polymer materials</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20molecule" title=" single molecule"> single molecule</a>, <a href="https://publications.waset.org/abstracts/search?q=super-resolution%20techniques" title=" super-resolution techniques"> super-resolution techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=conformation" title=" conformation"> conformation</a> </p> <a href="https://publications.waset.org/abstracts/57901/single-molecule-analysis-of-structure-and-dynamics-in-polymer-materials-by-super-resolution-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57901.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1902</span> Reduction of Wear via Hardfacing of Rotavator Blades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh%20Randhawa">Gurjinder Singh Randhawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonny%20Garg"> Jonny Garg</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukhraj%20Singh"> Sukhraj Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema"> Gurmeet Singh Cheema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A major problem related to the use of rotavator is wear of rotavator blades due to abrasion by soil hard particles, as it seriously affects tillage quality and agricultural production economy.

These blades are generally produced from low carbon or low alloy steel. During the field work i.e. preparing land for the cultivation these blades are subjected to severe wear conditions. Comparative wear tests on a regular rotavator blade and two kinds of hardfacing with electrodes were conducted in the field.

Polymer substances can lower the mobility ratio of the whole process by increasing the viscosity of injected water. Therefore, polymer flooding can increase volumetric sweep efficiency, which leads to a better recovery factor. Moreover, polymer adsorption onto rock surface can help decrease reservoir permeability contrast with high heterogeneity. Due to the reduction of the absolute permeability, effective permeability to water, representing flow ability of the injected fluid, is also reduced. Once polymer is adsorbed onto rock surface, polymer molecule can be desorbed when different fluids are injected. This study is performed to evaluate the effects of the adsorption and desorption process of polymer solutions to yield benefits on the oil recovery mechanism. A reservoir model is constructed by reservoir simulation program called STAR® commercialized by the Computer Modeling Group (CMG). Various polymer concentrations, starting times of polymer flooding process and polymer injection rates were evaluated with selected values of polymer desorption degrees including 0, 25, 50, 75 and 100%. The higher the value, the more adsorbed polymer molecules to return back to flowing fluid. According to the results, polymer desorption lowers polymer consumption, especially at low concentrations. Furthermore, starting time of polymer flooding and injection rate affect the oil production. The results show that waterflooding followed by earlier polymer flooding can increase the oil recovery factor while the higher injection rate also enhances the recovery. Polymer concentration is related to polymer consumption due to the two main benefits of polymer flooding control described above. Therefore, polymer slug size should be optimized based on polymer concentration. Polymer desorption causes polymer re-employment that is previously adsorbed onto rock surface, resulting in an increase of sweep efficiency in the further period of polymer flooding process. Even though waterflooding supports polymer injectivity, water cut at the producer can prematurely terminate the oil production. The injection rate decreases polymer adsorption due to decreased retention time of polymer flooding process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery%20technology" title="enhanced oil recovery technology">enhanced oil recovery technology</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20adsorption%20and%20desorption" title=" polymer adsorption and desorption"> polymer adsorption and desorption</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20flooding" title=" polymer flooding"> polymer flooding</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20simulation" title=" reservoir simulation"> reservoir simulation</a> </p> <a href="https://publications.waset.org/abstracts/61704/effects-of-polymer-adsorption-and-desorption-on-polymer-flooding-in-waterflooded-reservoir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61704.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1900</span> Study of Electrocoagulation on the Elimination of Chromium in Waste Water From an Electroplating Bath Using Aluminium Electrodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salim%20Ahmed">Salim Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrocoagulation has proven its effectiveness in industrial effluent treatment by eliminating pollutants, particularly metallic ones. The electrochemical processes that occur at aluminium electrodes give excellent performance. In this work, electrocoagulation tests were carried out on an industrial effluent from an electroplating bath located in Casablanca (Morocco). The aim was to remove chromium and reuse the purified water for other purposes within the company. To this end, we have optimised the operating parameters that affect the efficiency of electrocoagulation, such as electrical voltage, electrode material, stirring speed and distance between electrodes. We also evaluated these parameters. The effect on pH, conductivity, turbidity and chromium concentration. The tests were carried out in a perfectly stirred reactor on an industrial solution rich in chromium. The effluent concentration was 1000 mg/L of Cr6+. Chromium removal efficiency was determined for the following operating conditions: aluminium electrodes, regulated voltage of 6 volts and 12 volts, optimum stirring speed of 600 rpm and distance between electrodes of 2 cm. The sludge produced by electrocoagulation was characterised by X-ray diffractometry, infrared spectroscopy (IR) and scanning electron microscopy (SEM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater" title="wastewater">wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title=" electrocoagulation"> electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium" title=" aluminium"> aluminium</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium%20hydroxide" title=" aluminium hydroxide"> aluminium hydroxide</a> </p> <a href="https://publications.waset.org/abstracts/171096/study-of-electrocoagulation-on-the-elimination-of-chromium-in-waste-water-from-an-electroplating-bath-using-aluminium-electrodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171096.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1899</span> A Virtual Electrode through Summation of Time Offset Pulses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Cassar">Isaac Cassar</a>, <a href="https://publications.waset.org/abstracts/search?q=Trevor%20Davis"> Trevor Davis</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Kai%20Lo"> Yi-Kai Lo</a>, <a href="https://publications.waset.org/abstracts/search?q=Wentai%20Liu"> Wentai Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Retinal prostheses have been successful in eliciting visual responses in implanted subjects. As these prostheses progress, one of their major limitations is the need for increased resolution. As an alternative to increasing the number of electrodes, virtual electrodes may be used to increase the effective resolution of current electrode arrays. This paper presents a virtual electrode technique based upon time-offsets between stimuli. Two adjacent electrodes are stimulated with identical pulses with too short of pulse widths to activate a neuron, but one has a time offset of one pulse width. A virtual electrode of twice the pulse width was then shown to appear in the center, with a total width capable of activating a neuron. This can be used in retinal implants by stimulating electrodes with pulse widths short enough to not elicit responses in neurons, but with their combined pulse width adequate to activate a neuron in between them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title="electrical stimulation">electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprosthesis" title=" neuroprosthesis"> neuroprosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20implant" title=" retinal implant"> retinal implant</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20prosthesis" title=" retinal prosthesis"> retinal prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20electrode" title=" virtual electrode"> virtual electrode</a> </p> <a href="https://publications.waset.org/abstracts/14443/a-virtual-electrode-through-summation-of-time-offset-pulses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14443.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1898</span> Carbon Nanofibers Reinforced P(VdF-HFP) Based Gel Polymer Electrolyte for Lithium-Ion Battery Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjan%20Sil">Anjan Sil</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajni%20Sharma"> Rajni Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrata%20Ray"> Subrata Ray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of carbon nanofibers (CNFs) on the electrical properties of Poly(vinylidene ﬂuoride-hexaﬂuoropropylene) (P(VdF-HFP)) based gel polymer electrolytes has been investigated in the present work. The length and diameter ranges of CNFs used in the present work are 5-50 µm and 200-600 nm, respectively. The nanocomposite gel polymer electrolytes have been synthesized by solution casting technique with varying CNFs content in terms of weight percentage. Electrochemical impedance analysis demonstrates that the reinforcement of carbon nanofibers significantly enhances the ionic conductivity of the polymer electrolyte. The decrease of crystallinity of P(VdF-HFP) due the addition of CNFs has been confirmed by X-ray diffraction (XRD). The interaction of CNFs with various constituents of nanocomposite gel polymer electrolytes has been assessed by Fourier Transform Infrared (FTIR) spectroscopy. Moreover, CNFs added gel polymer electrolytes offer superior thermal stability as compared to that of CNFs free electrolytes as confirmed by Thermogravimetric analysis (TGA). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20electrolytes" title="polymer electrolytes">polymer electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=CNFs" title=" CNFs"> CNFs</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20conductivity" title=" ionic conductivity"> ionic conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=TGA" title=" TGA"> TGA</a> </p> <a href="https://publications.waset.org/abstracts/33161/carbon-nanofibers-reinforced-pvdf-hfp-based-gel-polymer-electrolyte-for-lithium-ion-battery-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1897</span> Zinc Oxide Nanorods Decorated Nanofibers Based Flexible Electrodes for Capacitive Energy Storage Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Kamran%20Sami">Syed Kamran Sami</a>, <a href="https://publications.waset.org/abstracts/search?q=Saqib%20Siddiqui"> Saqib Siddiqui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent times, flexible supercapacitors retaining high electrochemical performance and steadiness along with mechanical endurance has developed as a spring of attraction due to the exponential progress and innovations in energy storage devices. To meet the rampant increasing demand of energy storage device with the small form factor, a unique, low cost and high-performance supercapacitor with considerably higher capacitance and mechanical robustness is required to recognize their real-life applications. Here in this report, synthesis route of electrode materials with low rigidity and high charge storage performance is reported using 1D-1D hybrid structure of zinc oxide (ZnO) nanorods, and conductive polymer smeared polyvinylidene fluoride–trifluoroethylene (P(VDF–TrFE)) electrospun nanofibers. The ZnO nanorods were uniformly grown on poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) coated P(VDF-TrFE) nanofibers using hydrothermal growth to manufacture light weight, permeable electrodes for supercapacitor. The PEDOT: PSS coated P(VDF-TrFE) porous web of nanofibers act as framework with high surface area. The incorporation of ZnO nanorods further boost the specific capacitance by 59%. The symmetric device using the fabricated 1D-1D hybrid electrodes reveals fairly high areal capacitance of 1.22mF/cm² at a current density of 0.1 mA/cm² with a power density of more than 1600 W/Kg. Moreover, the fabricated electrodes show exceptional flexibility and high endurance with 90% and 76% specific capacitance retention after 1000 and 5000 cycles respectively signifying the astonishing mechanical durability and long-term stability. All the properties exhibited by the fabricated electrode make it convenient for making flexible energy storage devices with the low form factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZnO%20nanorods" title="ZnO nanorods">ZnO nanorods</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20endurance" title=" mechanical endurance"> mechanical endurance</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20supercapacitor" title=" flexible supercapacitor"> flexible supercapacitor</a> </p> <a href="https://publications.waset.org/abstracts/100794/zinc-oxide-nanorods-decorated-nanofibers-based-flexible-electrodes-for-capacitive-energy-storage-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100794.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">281</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1896</span> Transparent and Solution Processable Low Contact Resistance SWCNT/AZONP Bilayer Electrodes for Sol-Gel Metal Oxide Thin Film Transistor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Su%20Jeong%20Lee">Su Jeong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Il%20Lee"> Tae Il Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Han%20Kim"> Jung Han Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul-Hong%20Kim"> Chul-Hong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Gee%20Sung%20Chae"> Gee Sung Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Min%20Myoung"> Jae-Min Myoung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The contact resistance between source/drain electrodes and semiconductor layer is an important parameter affecting electron transporting performance in the thin film transistor (TFT). In this work, we introduced a transparent and the solution prossable single-walled carbon nanotube (SWCNT)/Al-doped ZnO nano particle (AZO NP) bilayer electrodes showing low contact resistance with indium-oxide (In2O3) sol gel thin film. By inserting low work function AZO NPs into the interface between the SWCNTs and the In2O3 which has a high energy barrier, we could obtain an electrical Ohmic contact between them. Finally, with the SWCNT-AZO NP bilayer electrodes, we successfully fabricated a TFT showing a field effect mobility of 5.38 cm2/V∙s at 250 °C. <p class="card-text"><strong>Keywords:</strong> <a
