Abstract In this study, a stepwise cyclic voltammetry approach was proposed to clarify the potential dependence of specific capacitance for reduced graphene oxide and ruthenium electrodes. Based on relationship between potential, working voltage window energy density RuO 2 //RuO supercapacitors (SCs) were maximized by modulating mass ratio. The with ratio 2.03 (close optimum ) extended about 188 % when compared that calculated at 0.56. former equivalent 304 increase in density. addition,...
Excess conductivities of polycrystalline Hg-1223 superconductor have been studied under high-pressure conditions. The critical temperature was chosen as the mean field transition . Above this temperature, normal state resistivity decreases with increasing pressure. relative change in w.r.t. pressure, namely , is about It much smaller than typical value for most high- superconductors. As a consequence due to applied fluctuation-induced conductivity also changed. experimental results were...
Composited molybdenum oxide and amorphous carbon (MoO3/C) as anode material for lithium ion batteries has been successfully synthesized by calcining polyaniline (PANI) doped with ammonium heptamolybdate tetrahydrate (AMo). The prepared electrode was characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) field emission scanning electron microscopy (FE-SEM). electrochemical performance of the investigated galvanostatic charge/discharge, cyclic voltammetry (CV),...
Abstract Polypyrrole (PPy) nanoparticles formed by chemical in situ polymerization were deposited on the hydrophilic/hydrophobic surface of SiO2 substrates to give diversely morphology, respectively. The morphologies PPy deposit investigated using optical microscope, scanning electron microscope (SEM), and atomic force (AFM) imaging techniques. morphology Y- T-shape wrinkles was observed hydrophilic substrate, while polygon-shape hydrophobic this distinction is due difference energy between...

The conducting polypyrrole (PPy) nanofilms have been in-situ polymerized on quartz substrates under various high reaction pressures (0.1–600 MPa). effects of the applied pressure films carefully investigated through UV-Vis, FT-IR, SEM, AFM and conductivity measurement. effect thickness electrical PPy discussed. A three-dimensional relationship between film thickness, pressure, has also described in text. Our results may provide a guide for studying polymerization pyrrole its derivatives pressure.
The understanding of the spin gap phenomenon in normal state high temperature superconductors can provide mechanism superconductivity. A specific function thermal excitation for quasiparticles was introduced based on experimental relationship between resistivity and temperature. This describes deviation from T-linear w.r.t. superconductors. With this function, is naturally introduced. Our results indicate that behavior closely related not only to oxygen deficiency but also structural change...
