Nickel hydroxide (Ni(OH)2) is commonly utilized in catalytic, sensing, energy storage and recording media. It has unique physical and chemical properties such as high redox activity, high power density, high chemical stability and cyclability. Ni(OH)2 is reported to have highly pseudocapacitive properties, which make it promising electrode materials for supercapacitors. In this work, we report on the fabrication and capacitive properties characterization of supercapacitors with nanocomposite Ni(OH)2 and silver (Ag) nanowire network electrodes . Ag nanowire network on polyethylene terephthalate (PET) and glass substrates provided high conductivity and a template for the attachment of Ni(OH)2. Electrochemical properties such as specific capacity and cycling ability of supercapacitors with coaxial composite electrodes were then investigated through cyclic voltammetry, chronopotentiometry, electrochemical impedance spectroscopy. A specific capacitance of 1165.2 F/g was obtained for the nanocomposite electrodes, which was higher than that of bulk Ni(OH)2 electrodes. Our results reveal the potential use of the Ag nanowire/ Ni(OH)2 nanocomposites in flexible supercapacitor electrodes that can be fabricated through simple solution based methods and the method investigated herein can be simply adapted to industrial scale fabrication.

DEVELOPMENT OF BORIDES/BORATES FOR ENERGY STORAGE DEVICES Bahtiyar, Doruk; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2022-9) For many years, materials in the form of metal sulfides, oxides, phosphates, and titanates have been developed as cathode and anode active materials to be used in energy storage devices. Borides and borates, recently, attracted the attention of researchers in this field. In this study, for the development of a new class of materials for energy storage applications, synthesis and characterization of metal (Fe, Mo, Mn, and V) borides and (Mn, and Y)borates were carried out. The obtained materials were tested ...
Zinc oxide nanowire networks for macroelectronic devices Ünalan, Hüsnü Emrah; Hiralal, Pritesh; Dalal, Sharvari; Chu, Daping; Eda, Goki; Teo, K. B. K.; Chhowalla, Manish; Milne, William I.; Amaratunga, Gehan A. J. (AIP Publishing, 2009-04-20) Highly transparent zinc oxide (ZnO) nanowire networks have been used as the active material in thin film transistors (TFTs) and complementary inverter devices. A systematic study on a range of networks of variable density and TFT channel length was performed. ZnO nanowire networks provide a less lithographically intense alternative to individual nanowire devices, are always semiconducting, and yield significantly higher mobilites than those achieved from currently used amorphous Si and organic TFTs. These r...
Vacuum-processed polyethylene as a dielectric for low operating voltage organic field effect transistors Kanbur, Yasin; Irimia-Vladu, Mihai; Glowacki, Eric D.; Voss, Gundula; Baumgartner, Melanie; Schwabegger, Guenther; Leonat, Lucia; Ullah, Mujeeb; Sarica, Hizir; ERTEN ELA, ŞULE; Schwoediauer, Reinhard; Sitter, Helmut; Kucukyavuz, Zuhal; Bauer, Siegfried; Sariciftci, Niyazi Serdar (2012-05-01) We report on the fabrication and performance of vacuum-processed organic field effect transistors utilizing evaporated low-density polyethylene (LD-PE) as a dielectric layer. With C-60 as the organic semiconductor, we demonstrate low operating voltage transistors with field effect mobilities in excess of 4 cm(2)/Vs. Devices with pentacene showed a mobility of 0.16 cm(2)/Vs. Devices using tyrian Purple as semiconductor show low-voltage ambipolar operation with equal electron and hole mobilities of similar to...
Water soluble laurate-stabilized ruthenium(0) nanoclusters catalyst for hydrogen generation from the hydrolysis of ammonia-borane: High activity and long lifetime DURAP, FEYYAZ; Zahmakiran, Mehmet; Özkar, Saim (2009-09-01) The simplest amine-borane, considered as solid hydrogen storage material, ammonia-borane (H(3)NBH(3)) can release hydrogen gas upon catalytic hydrolysis under mild conditions. Herein, we report the preparation of a novel catalyst, water dispersible laurate-stabilized ruthenium(0) nanoclusters from the dimethylamine-borane reduction of ruthenium(III) chloride in sodium laurate solution at room temperature. The ruthenium nanoclusters in average size of 2.6 +/- 1.2 nm were isolated from the solution and well c...
Quantum chemical studies on EGDN and its monovalent ions Türker, Burhan Lemi (Elsevier BV, 2005-03-17) An explosive material, ethylene glycol dinitrate (EGDN) and its mono ionic forms have been subjected to semiempirical AM1 (UHF) and ab initio 6-31G (UHF) type quantum chemical analyses. The AM1 treatment reveals that the neutral and anionic forms are exothermic whereas the cation is endothermic. All of the systems are found to be stable (by AM1 and 6-31G methods) but the calculations indicate that plus and minus charge developments in AM1 treatment and minus charge development in 6-31G treatment cause drast...
