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">9396</span> Simple Fabrication of Au (111)-Like Electrode and Its Applications to Electrochemical Determination of Dopamine and Ascorbic Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahrah%20Thamer%20Althagafi">Zahrah Thamer Althagafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20I.%20Awad"> Mohamed I.

Then, the voltammetric behaviour of dopamine (DA) and ascorbic acid (AA) on the thus modified electrode is investigated. Electrochemical characterization of the modified electrode is achieved using cyclic voltammetry and square wave voltammetry. For the binary mixture of DA and AA, the results showed that Au (111)-like electrode exhibits excellent electrocatalytic activity towards the oxidation of DA and AA. This allows highly selective and simultaneous determination of DA and AA. The effect of various experimental parameters on the voltammetric responses of DA and AA was investigated. The enrichment of the Au (111) facet of the poly-Au electrode is thought to be behind the electrocatalytic activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20electrode" title="gold electrode">gold electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=electroanalysis" title=" electroanalysis"> electroanalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocatalysis" title=" electrocatalysis"> electrocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=monolayers" title=" monolayers"> monolayers</a>, <a href="https://publications.waset.org/abstracts/search?q=self-assembly" title=" self-assembly"> self-assembly</a>, <a href="https://publications.waset.org/abstracts/search?q=cysteine" title=" cysteine"> cysteine</a>, <a href="https://publications.waset.org/abstracts/search?q=dopamine" title=" dopamine"> dopamine</a>, <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid" title=" ascorbic acid"> ascorbic acid</a> </p> <a href="https://publications.waset.org/abstracts/117052/simple-fabrication-of-au-111-like-electrode-and-its-applications-to-electrochemical-determination-of-dopamine-and-ascorbic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117052.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">195</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">9395</span> Optimized Dye-Sensitized Solar Cell Using Natural Dye and Counter Electrode from Robusta Coffee Beans Peel Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomi%20Setiawan">Tomi Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahyu%20Y.%20Subekti"> Wahyu Y.

DSSC has two important parts of dye and counter electrode. Anthocyanin compounds in the coffee beans peel can be potential as natural dye and also counter electrodes as activated carbon in the DSSC system. The purpose of this research is to find out how to isolate Anthocyanin, manufacture of counter electrode, and to know the efficiency of counter electrode produced from the coffee pulp waste in DSSC prototype. In this research we used 2 x 2 cm FTO glass coated carbon paste with a thickness variation of 100 μL, 200 μL and 300 μL as counter electrode and other FTO glass coated with TiO₂ paste as work electrode, then two FTO glasses are connected to form a sandwich-liked structure and add Triiodide electrolyte solution in its gap, thus forming a DSSC prototype. The results showed that coffee pulp waste contains anthocyanin of 12.23 mL/80gr and it can produce activated carbon. The characterization performed shows that the UV-Vis Anthocyanin result is at wavelength of ultra violet area that is 219,50 nm with absorbance value equal to 1,469, and maximum wavelength at visible area is 720,00 nm with absorbance value equal to 0,013. The functional groups contained in the anthocyanin are O-H groups at wave numbers 3385.60 cm⁻¹, C = O groups at wave numbers 1618.63 cm⁻¹, and C-O-C groups at 1065.40 cm⁻¹ wave numbers. Morphological characterization using the SEM shows the activated carbon surface area becomes larger and evenly distributed.

Uvarov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Supercapacitors are one of the most promising devices for energy storage applications as they can provide higher power density than batteries and higher energy density than conventional dielectric capacitors. Carbon materials with various microtextures are considered as main candidates for supercapacitors in terms of high surface area, interconnected pore structure, controlled pore size, high electrical conductivity and environmental friendliness. The specific capacitance (C) of the electrode material of the Electrochemical Double Layer Capacitors (EDLC) is known to depend on the specific surface area (Ss) and the pore structure. Activated carbons are most commonly used in supercapacitors because of their high surface area (Ss ≥ 1000 m2/g), good adhesion to electrolytes and low cost. In this work, electrochemical properties of new microporous and mesoporous carbon electrode materials were studied. The aim of the work was to investigate the relationship between the specific capacitance and specific surface area in a series of materials prepared from different organic precursors.. As supporting matrixes different carbon samples with Ss = 100-2000 m2/g were used. The materials were modified by treatment in acids (H2SO4, HNO3, acetic acid) in order to enable surface hydrophilicity. Then nanoparticles of transition metal oxides (for example NiO) were deposited on the carbon surfaces using methods of salts impregnation, mechanical treatment in ball mills and the precursors decomposition. The electrochemical characteristics of electrode hybrid materials were investigated in a symmetrical two-electrode cell using an impedance spectroscopy, voltammetry in both potentiodynamic and galvanostatic modes. It was shown that the value of C for the materials under study strongly depended on the preparation method of the electrode and the type of electrolyte (1 M H2SO4, 6 M KOH, 1 M LiClO4 in acetonitryl). Specific capacity may be increased by the introduction of nanoparticles from 50-100 F/g for initial carbon materials to 150-300 F/g for nanocomposites which may be used in supercapacitors. The work is supported by the по SC-14.604.21.0013. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supercapacitors" title="supercapacitors">supercapacitors</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20electrode" title=" carbon electrode"> carbon electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=mesoporous%20carbon" title=" mesoporous carbon"> mesoporous carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title=" electrochemistry "> electrochemistry </a> </p> <a href="https://publications.waset.org/abstracts/34634/carbon-electrode-materials-for-supercapacitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34634.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">9393</span> An Automated Sensor System for Cochlear Implants Electrode Array Insertion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Hou">Lei Hou</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinli%20Du"> Xinli Du</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Boulgouris"> Nikolaos Boulgouris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A cochlear implant, referred to as a CI, is a small electronic device that can provide direct electrical stimulation to the auditory nerve. During cochlear implant surgery, atraumatic electrode array insertion is considered to be a crucial step. However, during implantation, the mechanical behaviour of an electrode array inside the cochlea is not known. The behaviour of an electrode array inside of the cochlea is hardly identified by regular methods. In this study, a CI electrode array capacitive sensor system is proposed. It is able to automatically determine the array state as a result of the capacitance variations. Instead of applying sensors to the electrode array, the capacitance information from the electrodes will be gathered and analysed. Results reveal that this sensing method is capable of recognising different states when fed into a pre-shaped model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implant" title="cochlear implant">cochlear implant</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=hearing%20preservation" title=" hearing preservation"> hearing preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=insertion%20force" title=" insertion force"> insertion force</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitive%20sensing" title=" capacitive sensing"> capacitive sensing</a> </p> <a href="https://publications.waset.org/abstracts/80147/an-automated-sensor-system-for-cochlear-implants-electrode-array-insertion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80147.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">238</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">9392</span> Study of Parameters Affecting the Electrostatic Attractions Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Sabermand">Vahid Sabermand</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Hojjat"> Yousef Hojjat</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Hasanzadeh"> Majid Hasanzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper contains two main parts.

The DSSC with a rGO+CuInS2 counter electrode exhibits a power conversion efficiency of 5.93%; better than the corresponding values for a DSSC with a CuInS2 counter electrode, and comparable to that of a reference DSSC with a Pt counter electrode. The excellent photoelectric performance of the rGO+CuInS2 counter electrode was attributed to its high specific surface area, which facilitated permeation of the liquid electrolytes, promoted electron and ion transfer and provided numerous catalytically active sites for the oxidation reaction of the electrolytic (I- /I3-). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cells" title="dye-sensitized solar cells">dye-sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20electrode" title=" counter electrode"> counter electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a> </p> <a href="https://publications.waset.org/abstracts/68098/electrospinning-in-situ-synthesis-of-graphene-doped-copper-indium-disulfide-composite-nanofibers-for-efficient-counter-electrode-in-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68098.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">457</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">9390</span> Mathematical Modeling of Switching Processes in Magnetically Controlled MEMS Switches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergey%20M.%20Karabanov">Sergey M.

Currently, there is a MEMS switch design with a flexible ferromagnetic electrode in the form of a fixed-terminal beam, with an electrode fastened on a straight or cranked anchor. The basic performance characteristics of magnetically controlled MEMS switches (service life, sensitivity, contact resistance, fast response) are largely determined by the flexible electrode design. To ensure the stable and controlled motion of the flexible electrode, it is necessary to provide the optimal design of a flexible electrode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20electrode" title="flexible electrode">flexible electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetically%20controlled%20MEMS" title=" magnetically controlled MEMS"> magnetically controlled MEMS</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20stress" title=" mechanical stress"> mechanical stress</a> </p> <a href="https://publications.waset.org/abstracts/99674/mathematical-modeling-of-switching-processes-in-magnetically-controlled-mems-switches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99674.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">180</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">9389</span> Investigation of the Effect of Nickel Electrodes as a Stainless Steel Buffer Layer on the Shielded Metal Arc Welding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meisam%20Akbari">Meisam Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hossein%20Elahi"> Seyed Hossein Elahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mashadgarmeh"> Mohammad Mashadgarmeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of nickel-electrode as a stainless steel buffer layer is considered.

The split-ring electrode can be opened up to encircle the sciatic nerve. The four electrodes can be bent to sit on top of the nerve and hold the device in position, while the split-ring frame remains flat. In comparison, while traditional cuff electrodes can only fit certain sizes of the nerve, the developed device can fit a variety of rat sciatic nerve dimensions from 0.6 mm to 1.0 mm, and adapt to the chronic changes in the nerve as the electrode tips are bendable.

The tungsten electrodes doped with emitter oxides of rare earth oxides such as La₂O₃, Th₂O₃, Y₂O₃, CeO₂ and ZrO₂ feature a comparatively lower work function than tungsten and thus have superior emission characteristics due to lesser surface temperature of the cathode. The local change in concentration of these emitter particles in tungsten electrode due to high temperature diffusion (chemical transport) can change its functional properties like electrode temperature, work function, electron emission, and stability of the electrode tip shape. The resulting increment in tip surface temperature results in the electrode material loss. It was also observed that the tungsten recrystallizes to large grains at high temperature. When the shape of grain boundaries are granular in shape, the intergranular diffusion of oxide emitter particles takes more time to reach the electrode surface. In the experimental work, the microstructure of the used electrode's tip surface will be studied by scanning electron microscope and reflective X-ray technique in order to gauge the extent of the diffusion and chemical reaction of emitter particles. Besides, a simulated model is proposed to explain the effect of oxide particles diffusion on the electrode’s microstructure, electron emission characteristics, and electrode tip erosion. This model suggests metallurgical modifications in tungsten electrode to enhance its erosion resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rare-earth%20emitter%20particles" title="rare-earth emitter particles">rare-earth emitter particles</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature-dependent%20diffusion" title=" temperature-dependent diffusion"> temperature-dependent diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=TIG%20welding" title=" TIG welding"> TIG welding</a>, <a href="https://publications.waset.org/abstracts/search?q=Tungsten%20electrode" title=" Tungsten electrode"> Tungsten electrode</a> </p> <a href="https://publications.waset.org/abstracts/89406/the-chemical-transport-mechanism-of-emitter-micro-particles-in-tungsten-electrode-a-metallurgical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89406.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">186</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">9381</span> Studies on the Feasibility of Cow’s Urine as Non-Conventional Energy Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Rajak">Raj Kumar Rajak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Mishra"> Bharat Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-batteries represent an entirely new long-term, reasonable, reachable, and eco-friendly approach to generation of sustainable energy.

The electrode also sustained robust stability throughout the 50 h of chronopotentiometry studies under alkaline electrolyte conditions, thus proving to be prospective electrode material for efficient OER in electrochemical water splitting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20splitting" title="water splitting">water splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemicals" title=" phytochemicals"> phytochemicals</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen%20evaluation%20reaction" title=" oxygen evaluation reaction"> oxygen evaluation reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Tafel%27s%20slope" title=" Tafel's slope"> Tafel's slope</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/165993/cufeox-based-nano-rose-electrocatalysts-for-oxygen-evolution-reaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165993.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">116</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">9379</span> Improved Embroidery Based Textile Electrodes for Sustainability of Impedance Measurement Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bulcha%20Belay%20Etana">Bulcha Belay Etana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Research shows that several challenges are to be resolved for textile sensors and wearable smart textiles systems to make it accurate and reproducible minimizing variability issues when tested. To achieve this, we developed stimulating embroidery electrode with three different filling textiles such as 3Dknit, microfiber, and nonwoven fabric, and tested with FTT for high recoverability on compression. Hence The impedance characteristics of wetted electrodes were caried out after 1hr of wetting under normal environmental conditions. The wetted 3D knit (W-3D knit), Wetted nonwoven (W-nonwoven), and wetted microfiber (W-microfiber) developed using Satin stitch performed better than a dry standard stitch or dry Satin stitch electrodes. Its performance was almost the same as that of the gel electrode (Ag/AgCl) as shown by the impedance result in figure 2 .The impedance characteristics of Dry and wetted 3D knit based Embroidered electrodes are better than that of the microfiber, and nonwoven filling textile. This is due to the fact that 3D knit fabric has high recoverability on compression to retain electrolyte gel than microfiber, and nonwoven. However,The non-woven fabric held the electrolyte for longer time without releasing it to the skin when needed, thus making its impedance characteristics poor as observed from the results. Whereas the dry Satin stitch performs better than the standard stitch based developed electrode. The inter electrode distance of all types of the electrode was 25mm, with the area of the electrode being 20mm by 20mm.

The study investigates the impacts of an S-vacancy induced biphasic design on the overpotential and Tafel slope. According to the findings, the NiSx/CuSx/NF electrode with S-vacancy defects displays stronger oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) activity with lower overpotential and a steeper Tafel slope than the non-defect sample. NiSx/CuSx/NF exhibits the lowest overpotential value of 212 mV vs reversible hydrogen electrode (RHE) for OER and −109 mV vs RHE for HER at 10 mA cm−2. Tafel slope of 25.4 mV dec−1 for OER and −108 mV dec−1 for OER found of that electrode. The electrochemical surface area (ECSA) and diffusion impedance of the electrode is calculated. The maximum ECSA, lowest series resistance and lowest charge transfer resistance are found in the *NiSx/CuSx/NF sample with S-vacancy defects, showing increased electrical conductivity and quick charge transfer kinetics. The *NiSx/CuSx/NF electrode was found to be stable for 80 hours in pure water splitting and 20 hours in sea-water splitting. The investigation comes to the conclusion that the enhanced water splitting activity and electrical conductivity of the electrode are caused by S-vacancy defects resulting in improved water splitting performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20splitting" title="water splitting">water splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocatalyst" title=" electrocatalyst"> electrocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=biphasic%20design" title=" biphasic design"> biphasic design</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title=" electrodeposition"> electrodeposition</a> </p> <a href="https://publications.waset.org/abstracts/165992/coppernickel-sulfide-catalyst-electrodeposited-on-nickel-foam-for-efficient-water-splitting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165992.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">74</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">9377</span> Carbon-Nanodots Modified Glassy Carbon Electrode for the Electroanalysis of Selenium in Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azeez%20O.%20Idris">Azeez O.

The carbon nanodots were synthesised by green and facile approach and characterised using scanning electron microscopy, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy. The CNDT was used to fabricate an electrochemical sensor for the quantification of Se(IV) in water. The modification of glassy carbon electrode (GCE) with carbon nanodots led to an increase in the electroactive surface area of the electrode, which enhances the redox current peak of [Fe(CN)₆]₃₋/₄‒ in comparison to the bare GCE. Using the square wave voltammetry, the detection limit and quantification limit of 0.05 and 0.167 ppb were obtained under the optimised parameters using deposition potential of -200 mV, 0.1 M HNO₃ electrolyte, electrodeposition time of 60 s, and pH 1. The results further revealed that the GCE-CNDT was not susceptible to many interfering cations except Cu(II) and Pb(II), and Fe(II). The sensor fabrication involves a one-step electrode modification and was used to detect Se(IV) in a real water sample, and the result obtained is in agreement with the inductively coupled plasma technique. Overall, the electrode offers a cheap, fast, and sensitive way of detecting selenium in environmental matrices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanodots" title="carbon nanodots">carbon nanodots</a>, <a href="https://publications.waset.org/abstracts/search?q=square%20wave%20voltammetry" title=" square wave voltammetry"> square wave voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomaterials" title=" nanomaterials"> nanomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=selenium" title=" selenium"> selenium</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a> </p> <a href="https://publications.waset.org/abstracts/150663/carbon-nanodots-modified-glassy-carbon-electrode-for-the-electroanalysis-of-selenium-in-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150663.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">9376</span> BiVO₄‑Decorated Graphite Felt as Highly Efficient Negative Electrode for All-Vanadium Redox Flow Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Manaye%20Kabtamu">Daniel Manaye Kabtamu</a>, <a href="https://publications.waset.org/abstracts/search?q=Anteneh%20Wodaje%20Bayeh"> Anteneh Wodaje Bayeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the development and utilization of new energy technology, people’s demand for large-scale energy storage system has become increasingly urgent. Vanadium redox flow battery (VRFB) is one of the most promising technologies for grid-scale energy storage applications because of numerous attractive features, such as long cycle life, high safety, and flexible design. However, the relatively low energy efficiency and high production cost of the VRFB still limit its practical implementations. It is of great attention to enhance its energy efficiency and reduce its cost. One of the main components of VRFB that can impressively impact the efficiency and final cost is the electrode materials, which provide the reactions sites for redox couples (V₂₊/V³⁺ and VO²⁺/VO₂⁺). Graphite felt (GF) is a typical carbon-based material commonly employed as electrode for VRFB due to low-cost, good chemical and mechanical stability. However, pristine GF exhibits insufficient wettability, low specific surface area, and poor kinetics reversibility, leading to low energy efficiency of the battery. Therefore, it is crucial to further modify the GF electrode to improve its electrochemical performance towards VRFB by employing active electrocatalysts, such as less expensive metal oxides. This study successfully fabricates low-cost plate-like bismuth vanadate (BiVO₄) material through a simple one-step hydrothermal route, employed as an electrocatalyst to adorn the GF for use as the negative electrode in VRFB. The experimental results show that BiVO₄-3h exhibits the optimal electrocatalytic activity and reversibility for the vanadium redox couples among all samples. The energy efficiency of the VRFB cell assembled with BiVO₄-decorated GF as the negative electrode is found to be 75.42% at 100 mA cm−2, which is about 10.24% more efficient than that of the cell assembled with heat-treated graphite felt (HT-GF) electrode. The possible reasons for the activity enhancement can be ascribed to the existence of oxygen vacancies in the BiVO₄ lattice structure and the relatively high surface area of BiVO₄, which provide more active sites for facilitating the vanadium redox reactions. Furthermore, the BiVO₄-GF electrode obstructs the competitive irreversible hydrogen evolution reaction on the negative side of the cell, and it also has better wettability. Impressively, BiVO₄-GF as the negative electrode shows good stability over 100 cycles. Thus, BiVO₄-GF is a promising negative electrode candidate for practical VRFB applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BiVO%E2%82%84%20electrocatalyst" title="BiVO₄ electrocatalyst">BiVO₄ electrocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20energy%20storage" title=" electrochemical energy storage"> electrochemical energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite%20felt" title=" graphite felt"> graphite felt</a>, <a href="https://publications.waset.org/abstracts/search?q=vanadium%20redox%20flow%20battery" title=" vanadium redox flow battery"> vanadium redox flow battery</a> </p> <a href="https://publications.waset.org/abstracts/168036/bivo4decorated-graphite-felt-as-highly-efficient-negative-electrode-for-all-vanadium-redox-flow-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168036.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">1573</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">9375</span> Environmental Pb-Free Cu Front Electrode for Si-Base Solar Cell Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen-Hsi%20Lee">Wen-Hsi Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=C.G.%20Kao"> C.G.

In this process, PbO-based glass frit etched the DARCs and Ag recrystallized at the surface of Si, constructing the preliminary contact. The second step was in reducing atmosphere. In this process, CuO reduced to Cu and sintered. Besides, Ag nanoparticles recrystallized in the glass layer at interface due to the interactions between H2, Ag and PbO-based glass frit and the volatility of Pb, constructing the ohmic contact between electrode and solar cell.

Through the assessment of the current densities during charging, the efficiency of a range of formulations are compared. The Scanning vibrating electrode technique (SVET) is used extensively in the field of corrosion to measure area-averaged current densities of freely-corroding metal surfaces when fully immersed in electrolyte. Here, a Ni(OH)2 electrode is immersed in potassium hydroxide (30% w/v solution) electrolyte and charged using a range of applied currents. Samples are prepared whereby multiple coatings are applied to one substrate, separated by a non-conducting barrier, and charged using a constant current. With a known applied external current, electrode efficiencies can be calculated based on the current density outputs measured using SVET. When fully charged, a green Ni(OH)2 is oxidised to a black NiOOH surface. Distinct regions displaying high current density, and hence a faster oxidising reaction rate, are located using the SVET. This is confirmed by a darkening of the region upon transition to NiOOH. SVET is a highly effective tool for assessing homogeneity of electrodes during charge/discharge. This could prove particularly useful for electrodes where there are no visible surface appearance changes. Furthermore, a scanning Kelvin probe technique, traditionally used to assess underfilm delamination of organic coatings for the protection of metallic surfaces, is employed to study the change in phase of oxides, pre and post charging. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery" title="battery">battery</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20hydroxide" title=" nickel hydroxide"> nickel hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=SVET" title=" SVET"> SVET</a>, <a href="https://publications.waset.org/abstracts/search?q=printed" title=" printed"> printed</a> </p> <a href="https://publications.waset.org/abstracts/46748/the-scanning-vibrating-electrode-technique-svet-as-a-tool-for-optimising-a-printed-nioh2-electrode-under-charge-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46748.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">236</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">9372</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">303</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">9371</span> Studies on the Feasibility of Cow Dung as a Non-Conventional Energy Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Rajak">Raj Kumar Rajak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Mishra"> Bharat Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-batteries represent an entirely new long-term, reasonable, reachable and ecofriendly approach to produce sustainable energy.

C-Mg electrode pair shows maximum voltage and SCC (Short Circuit Current) while C-Zn electrode pair shows less OCV (Open Circuit Voltage) and SCC. We have chosen C-Zn electrodes because Mg electrodes are not economical. By the studies of different electrodes and cow dung, it is found that C-Zn electrode battery is more suitable. This result shows that the bio-batteries have the potency to full fill the need of electricity demand for lower energy equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-batteries" title="bio-batteries">bio-batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity" title=" electricity"> electricity</a>, <a href="https://publications.waset.org/abstracts/search?q=cow-dung" title=" cow-dung"> cow-dung</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodes" title=" electrodes"> electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=non-conventional" title=" non-conventional"> non-conventional</a> </p> <a href="https://publications.waset.org/abstracts/82579/studies-on-the-feasibility-of-cow-dung-as-a-non-conventional-energy-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82579.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">205</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">9370</span> Geophysical Exploration of Aquifer Zones by (Ves) Method at Ayma-Kharagpur, District Paschim Midnapore, West Bengal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mayank%20Sharma">Mayank Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater has been a matter of great concern in the past years due to the depletion in the water table. This has resulted from the over-exploitation of groundwater resources. Sub-surface exploration of groundwater is a great way to identify the groundwater potential of an area. Thus, in order to meet the water needs for irrigation in the study area, there was a need for a tube well to be installed. Therefore, a Geophysical investigation was carried out to find the most suitable point of drilling and sinking of tube well that encounters an aquifer. Hence, an electrical resistivity survey of geophysical exploration was used to know the aquifer zones of the area. The Vertical Electrical Sounding (VES) method was employed to know the subsurface geology of the area. Seven vertical electrical soundings using Schlumberger electrode array were carried out, having the maximum AB electrode separation of 700m at selected points in Ayma, Kharagpur-1 block of Paschim Midnapore district, West Bengal. The VES was done using an IGIS DDR3 Resistivity meter up to an approximate depth of 160-180m. The data was interpreted, processed and analyzed. Based on all the interpretations using the direct method, the geology of the area at the points of sounding was interpreted. It was established that two deeper clay-sand sections exist in the area at a depth of 50-70m (having resistivity range of 40-60ohm-m) and 70-160m (having resistivity range of 25-35ohm-m). These aquifers will provide a high yield of water which would be sufficient for the desired irrigation in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VES%20method" title="VES method">VES method</a>, <a href="https://publications.waset.org/abstracts/search?q=Schlumberger%20method" title=" Schlumberger method"> Schlumberger method</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20resistivity%20survey" title=" electrical resistivity survey"> electrical resistivity survey</a>, <a href="https://publications.waset.org/abstracts/search?q=geophysical%20exploration" title=" geophysical exploration"> geophysical exploration</a> </p> <a href="https://publications.waset.org/abstracts/144225/geophysical-exploration-of-aquifer-zones-by-ves-method-at-ayma-kharagpur-district-paschim-midnapore-west-bengal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144225.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">196</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">9369</span> Electrochemical Behavior of Cocaine on Carbon Paste Electrode Chemically Modified with Cu(II) Trans 3-MeO Salcn Complex</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alex%20Soares%20Castro">Alex Soares Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Matheus%20Manoel%20Teles%20de%20Menezes"> Matheus Manoel Teles de Menezes</a>, <a href="https://publications.waset.org/abstracts/search?q=Larissa%20Silva%20de%20Azevedo"> Larissa Silva de Azevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Carolina%20Caleffi%20Patelli"> Ana Carolina Caleffi Patelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Osmair%20Vital%20de%20Oliveira"> Osmair Vital de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20Thais%20Bruni"> Aline Thais Bruni</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Firmino%20de%20Oliveira"> Marcelo Firmino de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering the problem of the seizure of illicit drugs, as well as the development of electrochemical sensors using chemically modified electrodes, this work shows the study of the electrochemical activity of cocaine in carbon paste electrode chemically modified with Cu (II) trans 3-MeO salcn complex. In this context, cyclic voltammetry was performed on 0.1 mol.L⁻¹ KCl supporting electrolyte at a scan speed of 100 mV s⁻¹, using an electrochemical cell composed of three electrodes: Ag /AgCl electrode (filled KCl 3 mol.L⁻¹) from Metrohm® (reference electrode); a platinum spiral electrode, as an auxiliary electrode, and a carbon paste electrode chemically modified with Cu (II) trans 3-MeO complex (as working electrode). Two forms of cocaine were analyzed: cocaine hydrochloride (pH 3) and cocaine free base form (pH 8). The PM7 computational method predicted that the hydrochloride form is more stable than the free base form of cocaine, so with cyclic voltammetry, we found electrochemical signal only for cocaine in the form of hydrochloride, with an anodic peak at 1.10 V, with a linearity range between 2 and 20 μmol L⁻¹ had LD and LQ of 2.39 and 7.26x10-5 mol L⁻¹, respectively. The study also proved that cocaine is adsorbed on the surface of the working electrode, where through an irreversible process, where only anode peaks are observed, we have the oxidation of cocaine, which occurs in the hydrophilic region due to the loss of two electrons. The mechanism of this reaction was confirmed by the ab-inito quantum method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ab-initio%20computational%20method" title="ab-initio computational method">ab-initio computational method</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20method" title=" analytical method"> analytical method</a>, <a href="https://publications.waset.org/abstracts/search?q=cocaine" title=" cocaine"> cocaine</a>, <a href="https://publications.waset.org/abstracts/search?q=Schiff%20base%20complex" title=" Schiff base complex"> Schiff base complex</a>, <a href="https://publications.waset.org/abstracts/search?q=voltammetry" title=" voltammetry"> voltammetry</a> </p> <a href="https://publications.waset.org/abstracts/93544/electrochemical-behavior-of-cocaine-on-carbon-paste-electrode-chemically-modified-with-cuii-trans-3-meo-salcn-complex" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93544.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">194</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">9368</span> Development of Cathode for Hybrid Zinc Ion Supercapacitor Using Secondary Marigold Floral Waste for Green Energy Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syali%20Pradhan">Syali Pradhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Neetu%20Jha"> Neetu Jha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Marigold flower is used in religious places for offering and decoration purpose every day. The flowers are discarded near trees or in aquatic bodies. This floral waste can be used for extracting dyes or oils. Still the secondary waste remains after processing which need to be addressed. This research aims to provide green and clean power using secondary floral waste available after processing. The carbonization of floral waste produce carbon material with high surface area and enhance active site for more reaction. The Hybrid supercapacitors are more stable, offer improved operating temperature and use less toxic material compared to battery. They provide enhanced energy density compared to supercapacitors. Hence, hybrid supercapacitor designed using waste material would be more practicable for future energy application. Here, we present the utilization of carbonized floral waste as supercapacitor electrode material. This material after carbonization gets graphitized and shows high surface area, optimum porosity along with high conductivity. Hence, this material has been tested as cathode electrode material for high performance zinc storage hybrid supercapacitor. High energy storage along with high stability has been obtained using this cathodic waste material as electrode. <p class="card-text"><strong>Keywords:</strong> <a
