This is because these devices offer realistic applications of electrochromic materials in products such as sensors, windows and energy storage devices. The use of quasi-solid (gel) electrolytes for the construction of these ECDs is attractive because of their ease of preparation, availability, low cost, improved electrochromic performance, good ionic conductivity and prevention of leakages in ECDs. Herein, we developed a gel electrolyte consisting of polyacrylamide modified with succinonitrile for an ECD containing leucine-modified naphthalene diimide (NDI-L) as electrochromic material. The amount of succinonitrile in the gel was optimized, and the structure, surface morphology, and ionic conductivity of the electrolytes were assessed using microscopic techniques and electrochemical methods. The ECD fabricated with the gel electrolyte displayed good electrochromic performance with a fast switching response of up to 10 s and outstanding stability. These results add significant insight into understanding the inter- and intra-molecular interaction in succinonitrile gel electrolytes and provide a typical practicable high-performance gel electrolyte material for solid electrochromic devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromic%20device" title="electrochromic device">electrochromic device</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20electrolytes" title=" gel electrolytes"> gel electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=naphthalene%20diimide" title=" naphthalene diimide"> naphthalene diimide</a>, <a href="https://publications.waset.org/abstracts/search?q=succinonitrile" title=" succinonitrile"> succinonitrile</a> </p> <a href="https://publications.waset.org/abstracts/179328/succinonitrile-modified-polyacrylamide-as-a-quasi-solid-electrolyte-for-an-organic-based-electrochromic-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179328.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">60</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">1950</span> Optical and Electrochromic Properties of All-Solid-State Electrochromic Device Consisting of Amorphous WO₃ and Ni(OH)₂</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ta-Huang%20Sun">Ta-Huang Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Hao%20Hsieh"> Ming-Hao Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Chuan%20Wang"> Min-Chuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Der-Jun%20Jan"> Der-Jun Jan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrochromism refers to the persistent and reversible change of optical properties by an applied voltage pulse. There are many transition metal oxides exhibiting electrochromism, e.g. oxides of W, Ni, Ir, V, Ti, Co and Mo. Organic materials especially some conducting polymers such as poly(aniline), poly(3, 4-propylene- dioxythiophene) also received much attention for electrochromic (EC) applications. Electrochromic materials attract considerable interest because of their potential applications, such as information displays, smart windows, variable reflectance mirrors, and variable-emittance thermal radiators. In this study, the EC characteristics are investigated on an all-solid-state EC device composed of a-WO₃ and Ni(OH)₂ with a Ta₂O₅ protective layer which is prepared by magnetron sputtering. It is found that the transmittance modulation increases with decreasing the film thickness of Ta₂O₅. On the other hand, the transmittance modulation is 57% as the Ni(OH)₂/ITO is prepared by the linear-sweep potential cycling of the sputter-deposited Ta₂O₅/NiO/ITO in a 0.5 M LiClO₄+H₂O electrolyte. However, when Ni(OH)₂/ITO is prepared by a 0.01 M HCl electrolyte, the transmittance modulation of EC device can be improved to 61%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromic%20device" title="electrochromic device">electrochromic device</a>, <a href="https://publications.waset.org/abstracts/search?q=tungsten%20oxide" title=" tungsten oxide"> tungsten oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel"> nickel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ta%E2%82%82O%E2%82%85" title=" Ta₂O₅"> Ta₂O₅</a> </p> <a href="https://publications.waset.org/abstracts/52520/optical-and-electrochromic-properties-of-all-solid-state-electrochromic-device-consisting-of-amorphous-wo3-and-nioh2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52520.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">292</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">1949</span> Smart Energy Storage: W₁₈O₄₉ NW/Ti₃C₂Tₓ Composite-Enabled All Solid State Flexible Electrochromic Supercapacitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Hassan">Muhammad Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Celebi"> Kemal Celebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Developing a highly efficient electrochromic energy storage device with sufficient color fluctuation and significant electrochemical performance is highly desirable for practical energy-saving applications. Here, to achieve a highly stable material with a large electrochemical storage capacity, a W₁₈O₄₉ NW/Ti₃C₂Tₓ composite has been fabricated and deposited on a pre-assembled Ag and W₁₈O₄₉ NW conductive network by Langmuir-Blodgett technique. The resulting hybrid electrode composed of 15 layers of W₁₈O₄₉ NW/Ti₃C₂Tₓ exhibits an areal capacitance of 125 mF/cm², with a fast and reversible switching response. An optical modulation of 98.2% can be maintained at a current density of 5 mAcm⁻². Using this electrode, we fabricated a bifunctional symmetric electrochromic supercapacitor device having an energy density of 10.26 μWh/cm² and a power density of 0.605 mW/cm², with high capacity retention and full columbic efficiency over 4000 charge-discharge cycles. Meanwhile, the device displays remarkable electrochromic characteristics, including fast switching time (5 s for coloring and 7 s for bleaching) and a significant coloration efficiency of 116 cm²/C with good optical modulation stability. In addition, the device exhibits remarkable mechanical flexibility and fast switching while being stable over 100 bending cycles, which is promising for real-world applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MXene" title="MXene">MXene</a>, <a href="https://publications.waset.org/abstracts/search?q=nanowires" title=" nanowires"> nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitor" title=" supercapacitor"> supercapacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20diffusion" title=" ion diffusion"> ion diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochromic" title=" electrochromic"> electrochromic</a>, <a href="https://publications.waset.org/abstracts/search?q=coloration%20efficiency" title=" coloration efficiency"> coloration efficiency</a> </p> <a href="https://publications.waset.org/abstracts/184337/smart-energy-storage-w18o49-nwti3c2t-composite-enabled-all-solid-state-flexible-electrochromic-supercapacitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184337.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">76</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">1948</span> Effect of Gel Concentration on Physical Properties of an Electrochromic Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharan%20K.%20Indrakar">Sharan K.

An electrochromic device consisting of polyaniline (PANI) has a redox-active gel electrolyte placed between two conducting transparent fluorine-doped tin oxide glass substrates. The redox-active composite gel is a mixture of different concentrations of aniline (monomer), a water-soluble polymer poly (vinyl alcohol), hydrochloric acid, and an oxidant. The EC device shows the color change from dark green to transparent for the applied potential between -0.5 V to +2.0 V. The coloration and decoloration of the ECs were tested for electrochemical behavior using techniques such as cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS). The optical transparency of the EC devices was examined at two different biasing voltage conditions under UV-visible spectroscopic technique; the result showed 65% transmittance at 564 nm and zero transmittance when the cell was biased at 0.0 V and 2.0 V, the synthesized mol fraction gel was analyzed for surface morphology and structural properties by scanning electron microscopy and Fourier transformer spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromic" title="electrochromic">electrochromic</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20electrolyte" title=" gel electrolyte"> gel electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=polyaniline" title=" polyaniline"> polyaniline</a>, <a href="https://publications.waset.org/abstracts/search?q=conducting%20polymer" title=" conducting polymer"> conducting polymer</a> </p> <a href="https://publications.waset.org/abstracts/136080/effect-of-gel-concentration-on-physical-properties-of-an-electrochromic-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136080.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">138</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">1947</span> Qusai-Solid-State Electrochromic Device Based on PolyMethyl Methacrylate (PMMA)/Succinonitrile Gel Polymer Electrolyte</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jen-Yuan%20Wang">Jen-Yuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Chuan%20Wang"> Min-Chuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Der-Jun%20Jan"> Der-Jun Jan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polymer electrolytes can be classified into four major categories, solid polymer electrolytes (SPEs), gel polymer electrolytes (GPEs), polyelectrolytes and composite polymer electrolytes. SPEs suffer from low ionic conductivity at room temperature. The main problems for GPEs are the poor thermal stability and mechanical properties. In this study, a GPE containing PMMA and succinonitrile is prepared to solve the problems mentioned above, and applied to the assembly of a quasi-solid-state electrochromic device (ECD). In the polymer electrolyte, poly(methyl methacrylate) (PMMA) is the polymer matrix and propylene carbonate (PC) is used as the plasticizer. To enhance the mechanical properties of this GPE, succinonitrile (SN) is introduced as the additive. For the electrochromic materials, tungsten oxide (WO3) is used as the cathodic coloring film, which is fabricated by pulsed dc magnetron reactive sputtering. For the anodic coloring material, Prussian blue nanoparticles (PBNPs) are synthesized and coated on the transparent Sn-doped indium oxide (ITO) glass. The thickness of ITO, WO3 and PB film is 110, 170 and 200 nm, respectively. The size of the ECD is 5×5 cm2. The effect of the introduction of SN into the GPEs is discussed by observing the electrochromic behaviors of the WO3-PB ECD. Besides, the composition ratio of PC to SN is also investigated by measuring the ionic conductivity. The optimized ratio of PC to SN is 4:1, and the ionic conductivity under this condition is 6.34x10-5 S∙cm-1, which is higher than that of PMMA/PC (1.35x10-6 S∙cm-1) and PMMA/EC/PC (4.52x10-6 S∙cm-1). This quasi-solid-state ECD fabricated with the PMMA/SN based GPE shows an optical contrast of ca. 53% at 690 nm. The optical transmittance of the ECD can be reversibly modulated from 72% (bleached) to 19% (darkened), by applying potentials of 1.5 and -2.2 V, respectively. During the durability test, the optical contrast of this ECD remains 44.5% after 2400 cycles, which is 83% of the original one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromism" title="electrochromism">electrochromism</a>, <a href="https://publications.waset.org/abstracts/search?q=tungsten%20oxide" title=" tungsten oxide"> tungsten oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=prussian%20blue" title=" prussian blue"> prussian blue</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28methyl%20methacrylate%29" title=" poly(methyl methacrylate)"> poly(methyl methacrylate)</a>, <a href="https://publications.waset.org/abstracts/search?q=succinonitrile" title=" succinonitrile"> succinonitrile</a> </p> <a href="https://publications.waset.org/abstracts/52597/qusai-solid-state-electrochromic-device-based-on-polymethyl-methacrylate-pmmasuccinonitrile-gel-polymer-electrolyte" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52597.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">297</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">1946</span> The Effects of pH on the Electrochromism in Nickel Oxide Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Ta%C5%9Fk%C3%B6pr%C3%BC">T.

Electrochromic nickel oxide film was prepared by using a simple and inexpensive chemical deposition bath (CBD) technique onto fluorine-doped tin oxide (FTO) coated glass substrates from nickel nitrate solution. The films were ace centered cubic NiO with preferred orientation in the (2 0 0) direction. The electrochromic (EC) properties of the films were studied as a function of pH (8, 9, 10 and 11) in an aqueous alkaline electrolyte (0.3 M KOH) using cyclic voltammetry (CV). The EC cell was formed with the following configuration; FTO/nickel oxide film/0.3 M KOH/Pt The potential was cycled from 0.1 to 0.6V at diffferent potential sweep rates in the range 10- 50 mV/s. The films exhibit anodic electrochromism, changing colour from transparent to black.CV results of a nickel oxide film showed well-resolved anodic current peak at potential; 45 mV and cathodic peak at potential 28 mV. The structural, morphological, and optical changes in NiO film following the CV were investigated by means of X-ray diffractometer (XRD), field emission electron microscopy (FESEM) and UV-Vis- NIR spectrophotometry. No change was observed in XRD, besides surface morphology undergoes change due to the electrical discharge. The change in tansmittance between the bleached and colored state is 68% for the film deposited with pH=11 precursor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nickel%20oxide" title="nickel oxide">nickel oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20voltammetry" title=" cyclic voltammetry"> cyclic voltammetry</a> </p> <a href="https://publications.waset.org/abstracts/39351/the-effects-of-ph-on-the-electrochromism-in-nickel-oxide-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39351.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">306</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">1945</span> Effects of Phase and Morphology on the Electrochemical and Electrochromic Performances of Tungsten Oxide and Tungsten-Molybdenum Oxide Nanostructures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinjoo%20Jung">Jinjoo Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayeon%20Won"> Hayeon Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Doyeong%20Jeong"> Doyeong Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Hyung%20Kim"> Do Hyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present the electrochemical and electrochromic performance of the novel crystalline tungsten oxide and tungsten-molybdenum oxide nanostructures synthesized by utilizing solvo-thermal method with hexacarbonyl tungsten, hexacarbonyl molybdenum, and ethyl alcohol.

Suppose that a user intends to use a second-hand device for manufacturing products, and that the device is replaced with a new one. Any device failure is rectified through minimal repair, thereby incurring a fixed repair cost to the user. If the new device fails within the FRW period, minimal repair is performed at no cost to the user. After the FRW expires, a failed device is repaired and the cost of repair is incurred by the user. In this study, two profit models were developed, and the optimal replacement time and number of PM actions were determined to maximize profits. Finally, the influence of the optimal replacement time and number of PM actions were elaborated on, using numerical examples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=second-hand%20device" title="second-hand device">second-hand device</a>, <a href="https://publications.waset.org/abstracts/search?q=preventive%20maintenance" title=" preventive maintenance"> preventive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=replacement%20time" title=" replacement time"> replacement time</a>, <a href="https://publications.waset.org/abstracts/search?q=device%20failure" title=" device failure"> device failure</a> </p> <a href="https://publications.waset.org/abstracts/9223/replacement-time-and-number-of-preventive-maintenance-actions-for-second-hand-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9223.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">468</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">1942</span> A Review on the Re-Usage of Single-Use Medical Devices </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucas%20B.%20Naves">Lucas B.

The lunar samples and operating equipment are placed directly inside the storage device. The inside of the storage device is a high purity nitrogen environment to ensure that the sample is not contaminated by the Earth's environment. In order to ensure that the water and oxygen indicators in the storage device meet the sample requirements, a dynamic gas cycle is required between the storage device and the external purification equipment. However, the internal gas disturbance in the storage device can affect the operation of the sample. In this paper, the storage device model is established, and the tetrahedral mesh is established by Tetra/Mixed method. The influence of different inlet position and gas flow on the internal flow field disturbance is calculated, and the disturbed flow area should be avoided during the sampling operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lunar%20samples" title="lunar samples">lunar samples</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20disturbance" title=" gas disturbance"> gas disturbance</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20device" title=" storage device"> storage device</a>, <a href="https://publications.waset.org/abstracts/search?q=characteristic%20analysis" title=" characteristic analysis"> characteristic analysis</a> </p> <a href="https://publications.waset.org/abstracts/69595/analysis-of-gas-disturbance-characteristics-in-lunar-sample-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69595.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">294</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">1939</span> Syntheses in Polyol Medium of Inorganic Oxides with Various Smart Optical Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shian%20Guan">Shian Guan</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Bourdin"> Marie Bourdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabelle%20Trenque"> Isabelle Trenque</a>, <a href="https://publications.waset.org/abstracts/search?q=Younes%20Messaddeq"> Younes Messaddeq</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Cardinal"> Thierry Cardinal</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Penin"> Nicolas Penin</a>, <a href="https://publications.waset.org/abstracts/search?q=Issam%20Mjejri"> Issam Mjejri</a>, <a href="https://publications.waset.org/abstracts/search?q=Aline%20Rougier"> Aline Rougier</a>, <a href="https://publications.waset.org/abstracts/search?q=Etienne%20Duguet"> Etienne Duguet</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephane%20Mornet"> Stephane Mornet</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Gaudon"> Manuel Gaudon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At the interface of the studies performed by 3 Ph.D. students: Shian Guan (2017-2020), Marie Bourdin (2016-2019) and Isabelle Trenque (2012-2015), a single synthesis route: polyol-mediated process, was used with success for the preparation of different inorganic oxides. Both of these inorganic oxides were elaborated for their potential application as smart optical compounds. This synthesis route has allowed us to develop nanoparticles of zinc oxide, vanadium oxide or tungsten oxide. This route is with easy implementation, inexpensive and with large-scale production potentialities and leads to materials of high purity. The obtaining by this route of nanometric particles, however perfectly crystalline, has notably led to the possibility of doping these matrix materials with high doping ion concentrations (high solubility limits). Thus, Al3+ or Ga3+ doped-ZnO powder, with high doping rate in comparison with the literature, exhibits remarkable infrared absorption properties thanks to their high free carrier density. Note also that due to the narrow particle size distribution of the as-prepared nanometric doped-ZnO powder, the original correlation between crystallite size and unit-cell parameters have been established. Also, depending on the annealing atmosphere use to treat vanadium precursors, VO2, V2O3 or V2O5 oxides with thermochromic or electrochromic properties can be obtained without any impurity, despite the versatility of the oxidation state of vanadium. This is of more particular interest on vanadium dioxide, a relatively difficult-to-prepare oxide, whose first-order metal-insulator phase transition is widely explored in the literature for its thermochromic behavior (in smart windows with optimal thermal insulation). Finally, the reducing nature of the polyol solvents ensures the production of oxygen-deficient tungsten oxide, thus conferring to the nano-powders exotic colorimetric properties, as well as optimized photochromic and electrochromic behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inorganic%20oxides" title="inorganic oxides">inorganic oxides</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochromic" title=" electrochromic"> electrochromic</a>, <a href="https://publications.waset.org/abstracts/search?q=photochromic" title=" photochromic"> photochromic</a>, <a href="https://publications.waset.org/abstracts/search?q=thermochromic" title=" thermochromic"> thermochromic</a> </p> <a href="https://publications.waset.org/abstracts/97918/syntheses-in-polyol-medium-of-inorganic-oxides-with-various-smart-optical-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97918.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">221</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">1938</span> Product Design and Development of Wearable Assistant Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hao-Jun%20Hong">Hao-Jun Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Tang%20Huang"> Jung-Tang Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The world is gradually becoming an aging society, and with the lack of laboring forces, this phenomenon is affecting the nation’s economy growth.

It is based on the electromagnetic force induced between paired parallel wires carrying electrical currents. Using this concept, the actuator and sensor parts of the device were designed and analyzed while considering the practical limitations. Since the PWCC device only uses two wires for actuation part and sensing part, its fabrication process is extremely easier than the available MEMS/NEMS devices. The total gain and phase shift of the MEMS/NEMS device were calculated and investigated. Furthermore, the maximum gain and sensitivity of the MEMS/NEMS device were studied to demonstrate the capability and usability of the device for wide range of nanomaterials samples.

The nano-line patterns in PLED device was fabricated by advanced microstamping and ink-jet printing techniques. For high angles of observation with respect to the substrate surface normal, the light out intensity of the developed PLED device is increased from 0.05 (a.u.) up to 0.69 (a.u.) at the view angle 85 degree. The designed integration leads to 64% increase of the light out intensity compared with the conventional PLED device. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=triangular%20microlens" title="triangular microlens">triangular microlens</a>, <a href="https://publications.waset.org/abstracts/search?q=corrugation%20patterns" title=" corrugation patterns"> corrugation patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-line%20patterns" title=" nano-line patterns"> nano-line patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=PLED%20device" title=" PLED device"> PLED device</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20imprinting%20technology" title=" UV imprinting technology"> UV imprinting technology</a>, <a href="https://publications.waset.org/abstracts/search?q=microstamping" title=" microstamping"> microstamping</a> </p> <a href="https://publications.waset.org/abstracts/17239/enhancement-of-light-out-efficiency-of-pled-device-employing-designed-substrate-combined-with-nano-line-patterns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17239.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">478</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">1933</span> Automatic Battery Charging for Rotor Wings Type Unmanned Aerial Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeyeon%20Kim">Jeyeon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the development of the automatic battery charging device for the rotor wings type unmanned aerial vehicle (UAV) and the positioning method that can be accurately landed on the charging device when landing.

There were two objectives of this study. The first objective was to investigate the effect of non-chemical treatments on damage of bamboo shading device by powder-post beetle and fungi. The second aim of this study was to develop a prototype of bamboo shading device. The study of the effect of non-chemical treatments on damage of bamboo shading device by powder-post beetle in laboratory showed that, among seven treatments tested, wood vinegar treatment can protect powder-post beetle better than the original method up to 92.91%. It was also found that wood vinegar treatment can show the best performance in fungi protection and work better than the original method up to 40%. The second experiment was carried out by constructing four bamboo shading devices and installing them on a building for 28 days. All aspects of shading device were investigated in terms of their beauty, durability, and ease of construction and assembly. The final prototype was developed from the lessons drawn from these tested options. In conclusion this study showed the effectiveness of some natural preservatives against insect and fungi damage.

When children are out of sight or the caregivers cannot always pay attention to the situation, through the functions of this device, caregivers can immediately be informed to make sure that the children do not get lost or hurt, and thus, ensure their safety. Starting from this concept, a device is produced based on the relatively low-cost Bluetooth piconet system and a three-axis gyroscope sensor. This device can transmit data to a mobile phone app through Bluetooth, in order that the user can learn the situation at any time. By simply clipping the device in a pocket or on the waist, after switching on/starting the device, it will send data to the phone to detect the child’s fall and distance. Once the child is beyond the angle or distance set by the app, it will issue a warning to inform the phone owner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20care" title="children care">children care</a>, <a href="https://publications.waset.org/abstracts/search?q=piconet%20system" title=" piconet system"> piconet system</a>, <a href="https://publications.waset.org/abstracts/search?q=three-axis%20gyroscope" title=" three-axis gyroscope"> three-axis gyroscope</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20detection" title=" distance detection"> distance detection</a>, <a href="https://publications.waset.org/abstracts/search?q=falls%20detection" title=" falls detection"> falls detection</a> </p> <a href="https://publications.waset.org/abstracts/78252/bluetooth-piconet-system-for-child-care-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78252.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">597</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">1929</span> Transient Performance Analysis of Gate Inside Junctionless Transistor (GI-JLT)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sangeeta%20Singh">Sangeeta Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Pankaj%20Kumar"> Pankaj Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20N.%20Kondekar"> P.

In addition to this, various other device performance parameters namely, on/off current ratio, short channel effects (SCE), transconductance Generation Factor(TGF) and unity gain cut-off frequency (fT) and subthreshold slope (SS) of the GI-JLT and Gate-all-around junctionless transistor(GAA-JLT) have been analyzed and compared. GI-JLT shows better device performance characteristics than GAA-JLT for low power and high frequency applications, because of its larger gate electrostatic control on the device operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gate-inside%20junctionless%20transistor%20GI-JLT" title="gate-inside junctionless transistor GI-JLT">gate-inside junctionless transistor GI-JLT</a>, <a href="https://publications.waset.org/abstracts/search?q=gate-all-around%20junctionless%20transistor%20GAA-JLT" title=" gate-all-around junctionless transistor GAA-JLT"> gate-all-around junctionless transistor GAA-JLT</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation%20delay" title=" propagation delay"> propagation delay</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20delay%20product" title=" power delay product"> power delay product</a> </p> <a href="https://publications.waset.org/abstracts/9662/transient-performance-analysis-of-gate-inside-junctionless-transistor-gi-jlt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9662.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">579</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">1928</span> Improving Research Collaborations in Medical Device Development in Korea from an SMEs’ Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yoon%20Chung%20Kim">Yoon Chung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this coming aging society, medical device industry is expected to become one of the major industries. Since developing medical devices usually requires technology convergence, research collaboration is important, especially for some small and medium enterprises (SMEs) that do not have enough R&D resources in each related field. Collaboration in medical device development has some unique properties. Since it requires convergence technology, collaboration with different fields, and different types of people are often required. Since it requires clinical test, the development process usually takes longer and collaboration with hospitals is also required. However, despite these importance and uniqueness, collaboration in medical device development has not yet been widely studied. Thus, our research focuses on investigating collaborations in medical device development. For our research, we conducted surveys and interviews, especially with SMEs’ perspective in Korea. The result and discussion will be presented with a major impact factors for collaboration result, as well as future strategies that will improve and strengthen collaboration process in medical devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medical%20device" title="medical device">medical device</a>, <a href="https://publications.waset.org/abstracts/search?q=SME" title=" SME"> SME</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20collaboration" title=" research collaboration"> research collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical" title=" clinical"> clinical</a> </p> <a href="https://publications.waset.org/abstracts/49482/improving-research-collaborations-in-medical-device-development-in-korea-from-an-smes-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49482.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">329</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">1927</span> Photoplethysmography-Based Device Designing for Cardiovascular System Diagnostics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Botman">S.

Once phosphate is found in abundance in surface water, a series of adverse effects on an ecosystem can be initiated. Therefore, a portable and reliable method is needed to monitor the phosphate concentrations in the field. In this paper, an inexpensive dip strip device with the ascorbic acid/antimony reagent dried on blotting paper along with wet chemistry is developed for the detection of low concentrations of phosphate in water. Ammonium molybdate and sulfuric acid are separately stored in liquid form so as to improve significantly the lifetime of the device and enhance the reproducibility of the device’s performance. The limit of detection and quantification for the optimized device are 0.134 ppm and 0.472 ppm for phosphate in water, respectively. The device’s shelf life, storage conditions, and limit of detection are superior to what has been previously reported for the paper-based phosphate detection devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phosphate%20detection" title="phosphate detection">phosphate detection</a>, <a href="https://publications.waset.org/abstracts/search?q=paper-based%20device" title=" paper-based device"> paper-based device</a>, <a href="https://publications.waset.org/abstracts/search?q=molybdenum%20blue%20method" title=" molybdenum blue method"> molybdenum blue method</a>, <a href="https://publications.waset.org/abstracts/search?q=colorimetric%20assay" title=" colorimetric assay"> colorimetric assay</a> </p> <a href="https://publications.waset.org/abstracts/134960/a-highly-sensitive-dip-strip-for-detection-of-phosphate-in-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134960.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">170</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">1925</span> Application of Electrochromic Glazing for Reducing Peak Cooling Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ranojoy%20Dutta">Ranojoy Dutta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> HVAC equipment capacity has a direct impact on occupant comfort and energy consumption of a building. Glazing gains, especially in buildings with high window area, can be a significant contributor to the total peak load on the HVAC system, leading to over-sized systems that mostly operate at poor part load efficiency. In addition, radiant temperature, which largely drives occupant comfort in glazed perimeter zones, is often not effectively controlled despite the HVAC being designed to meet the air temperature set-point. This is due to short wave solar radiation transmitted through windows, that is not sensed by the thermostat until much later when the thermal mass in the room releases the absorbed solar heat to the indoor air. The implication of this phenomenon is increased cooling energy despite poor occupant comfort. EC glazing can significantly eliminate direct solar transmission through windows, reducing both the space cooling loads for the building and improving comfort for occupants near glazing. This paper will review the exact mechanism of how EC glazing would reduce the peak load under design day conditions, leading to reduced cooling capacity vs regular high-performance glazing. Since glazing heat transfer only affects the sensible load, system sizing will be evaluated both with and without the availability of a DOAS to isolate the downsizing potential of the primary cooling equipment when outdoor air is conditioned separately. Given the dynamic nature of glazing gains due to the sun’s movement, effective peak load mitigation with EC requires an automated control system that can predict solar movement and radiation levels so that the right tint state with the appropriate SHGC is utilized at any given time for a given façade orientation. Such an automated EC product will be evaluated for a prototype commercial office model situated in four distinct climate zones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromic%20glazing" title="electrochromic glazing">electrochromic glazing</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20sizing" title=" peak sizing"> peak sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=glazing%20load" title=" glazing load"> glazing load</a> </p> <a href="https://publications.waset.org/abstracts/117967/application-of-electrochromic-glazing-for-reducing-peak-cooling-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117967.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">130</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">1924</span> Novel Ultrasensitive Point of Care Device for Diagnosis of Human Schistosomiasis Mansoni</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aly">Ibrahim Aly</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Elawamy"> Waleed Elawamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Taher"> Hanan Taher</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Matar"> Amira Matar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schistosomiasis is infection with blood flukes of the genus Schistosoma, which are acquired trans-cutaneously by swimming or wading in contaminated freshwater.

The sensitivity of diagnostic device was 78 % and specificity was 85.2 %, with PPV and NPV of 86.2 % and 83.1 %, respectively.The Point of care device resulted in a good performance for the diagnosis of low-intensity infections, it was able to identify 19 out of 25 (76 %) individuals with ⩽7 eggs, 10 out of 14 individuals (71.4 %) with 11–99 eggs and 100 % of individuals with 100–399 eggs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schistosomiasis" title="schistosomiasis">schistosomiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=immunochromatography" title=" immunochromatography"> immunochromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=naon-dot-ELISa" title=" naon-dot-ELISa"> naon-dot-ELISa</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnostis%20device" title=" diagnostis device"> diagnostis device</a> </p> <a href="https://publications.waset.org/abstracts/178300/novel-ultrasensitive-point-of-care-device-for-diagnosis-of-human-schistosomiasis-mansoni" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178300.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">76</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> Design and Manufacture Detection System for Patient's Unwanted Movements during Radiology and CT Scan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anita%20Yaghobi">Anita Yaghobi</a>, <a href="https://publications.waset.org/abstracts/search?q=Homayoun%20Ebrahimian"> Homayoun Ebrahimian </a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the important tools that can help orthopedic doctors for diagnose diseases is imaging scan. Imaging techniques can help physicians in see different parts of the body, including the bones, muscles, tendons, nerves, and cartilage. During CT scan, a patient must be in the same position from the start to the end of radiation treatment. Patient movements are usually monitored by the technologists through the closed circuit television (CCTV) during scan. If the patient makes a small movement, it is difficult to be noticed by them. In the present work, a simple patient movement monitoring device is fabricated to monitor the patient movement. It uses an electronic sensing device. It continuously monitors the patient’s position while the CT scan is in process. The device has been retrospectively tested on 51 patients whose movement and distance were measured. The results show that 25 patients moved 1 cm to 2.5 cm from their initial position during the CT scan. Hence, the device can potentially be used to control and monitor patient movement during CT scan and Radiography. In addition, an audible alarm situated at the control panel of the control room is provided with this device to alert the technologists. It is an inexpensive, compact device which can be used in any CT scan machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CT%20scan" title="CT scan">CT scan</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a>, <a href="https://publications.waset.org/abstracts/search?q=X%20Ray" title=" X Ray"> X Ray</a>, <a href="https://publications.waset.org/abstracts/search?q=unwanted%20movement" title=" unwanted movement"> unwanted movement</a> </p> <a href="https://publications.waset.org/abstracts/32893/design-and-manufacture-detection-system-for-patients-unwanted-movements-during-radiology-and-ct-scan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32893.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">459</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">1922</span> Optical Repeater Assisted Visible Light Device-to-Device Communications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samrat%20Vikramaditya%20Tiwari">Samrat Vikramaditya Tiwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Atul%20Sewaiwar"> Atul Sewaiwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeon-Ho%20Chung"> Yeon-Ho Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Device-to-device (D2D) communication is considered a promising technique to provide wireless peer-to-peer communication services. Due to increasing demand on mobile services, available spectrum for radio frequency (RF) based communications becomes scarce. Recently, visible light communications (VLC) has evolved as a high speed wireless data transmission technology for indoor environments with abundant available bandwidth. In this paper, a novel VLC based D2D communication that provides wireless peer-to-peer communication is proposed. Potential low operating power devices for an efficient D2D communication over increasing distance of separation between devices is analyzed. Optical repeaters (OR) are also proposed to enhance the performance in an environment where direct D2D communications yield degraded performance. Simulation results show that VLC plays an important role in providing efficient D2D communication up to a distance of 1 m between devices. It is also found that the OR significantly improves the coverage distance up to 3.5 m. <p class="card-text"><strong>Keywords:</strong> <a
