Research ArticleOpen accessPhrase in the titleA General Formula for Ion Concentration-Dependent Electrical Conductivities in Polymer ElectrolytesMahardika Prasetya Aji, Masturi, Satria Bijaksana et al.Problem statement: The aim of this study is to develop a model for describing the effect of ion concentration on the electrical conductivity of polymer electrolytes by considering two mechanisms simultaneously: Enhancements of ion concentration and amorphous phase. Approach: The problems based on new observations in polymer electrolyte when ion concentration in the polymer electrolytes was increased, both the fraction … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 30 Mar 2012 · 8,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcofriendly and Simplified Synthetic Route for Polysulfone-based Solid-State Alkaline Electrolyte MembraneAphiruk Chaisena, Samroeng Krachodnok, Chutharat Khonkeng, Nittaya PantamasProblem statement: Recently the alkaline system for fuel cell enhance their presence because of possibility of no-precious-metal catalyst and low over potential at cathode reaction. The anion exchange membrane for alkaline membrane fuel cell should be a key technology in order to achieve the practical performance as fuel cells. Alkaline anion exchange membranes of high ionic conductivities are made from … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 15 Aug 2012 · 8,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotoacoustic Measurement of Thermal Diffusivity of Polypyrrole Conducting Polymer Composite FilmsM. Y. Lim, W. Mahmood Mat Yunus, A. Kassim, H.N.M.E. MahmudThe thermal diffusivity has been measured for the Polypyrrole-Polyethylene Glycol (PPy-PEG) composite films by the open photoacoustic method. The experimental data were analyzed for thermal diffusivity by fitting procedure. The different process parameters such as different concentrations of insulating polymer, monomer and electrolyte and the different voltages used to prepare the PPy-PEG composite films brought changes in thermal diffusivity. The … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical Studies of Carboxy Methycellulose-Chitosan Blend Biopolymer Doped Dodecyltrimethyl Ammonium Bromide Solid ElectrolytesNur Yasmin Abu Bakar, Nur Hafiza Mr. Muhamaruesa, Nur Ain Bashirah Aniskari, Mohd Ikmar Nizam Mohamad IsaIn this study, a polymer-blend system consist of Carboxy Methylcellulose (CMC)-Chitosan (CS) as blend biopolymer host and doped with various composition of Dodecyltrimethyl Ammonium Bromide (DTAB) were successfully prepared via solution casting techniques. The new system has been analyzed through Electrical Impedance Spectroscopy (EIS) from temperature 303 K until 393 K to determine the conductivity of biopolymer electrolytes in the … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 5 Mar 2015 · 7,649 accessesView PDFCite
