Organic, solid-state batteries require efficient solid electrolytes able to provide stable ion conduction. Here, based on ionic liquid (IL) polymers with chloride counterions as electrolyte materials for are presented. Acrylic monomers imidazolium substituents alkyl side groups that linked by spacers the acrylic group employed. The IL either converted thermally initiated radical polymerization ...

In the paper a linear-quadratic optimization problem (LCTOR) with unseparated two-point boundary conditions is considered. To solve this problem is proposed a new sweep algorithm which increases doubles the dimension of the original system. In contrast to the well-known methods, here it refuses to solve linear matrix and nonlinear Riccati equations, since the solution of such multi-point optimi...

The objective of this paper is to analyse the application of the Half-Sweep Gauss-Seidel (HSGS) method by using the Half-sweep approximation equation based on central difference (CD) and repeated trapezoidal (RT) formulas to solve linear fredholm integro-differential equations of first order. The formulation and implementation of the Full-Sweep Gauss-Seidel (FSGS) and HalfSweep Gauss-Seidel (HS...

Optoelectronic properties of hematite (α-Fe2O3) as a photoanode and the required over-potential in photo-assisted water splitting has been improved by presence of Co-Pi on its surface. In order to increase the lifetime of the photogenerated holes and lower the applied bias, cobalt-phosphate (Co-Pi) on nanostructured α-Fe2O3 by electrodeposition was de...

a r t i c l e i n f o Polarization curves from microbial fuel cells (MFCs) often show an unexpectedly large drop in voltage with increased current densities, leading to a phenomenon in the power density curve referred to as " power overshoot ". Linear sweep voltammetry (LSV, 1 mV s − 1) and variable external resistances (at fixed intervals of 20 min) over a single fed-batch cycle in an MFC both...

The anodic stripping voltammetry (ASV) was investigated to determine total mercury in solid samples using a gold electrode. deposited on the electrode preconcentration step. oxidation peak of irreversible. optimal conditions procedure were found be as follows: 0.05 mol L?1 HCl solution, deposition potential ?0.5 V vs. Ag/AgCl/KCls, time 40 s, and sweep rate 0.04 s?1. Under conditions, current s...

Abstract The electrolysis of water is one the most promising strategies to produce renewable fuels and it important develop an energy-conserving, low-cost easily prepared electrocatalyst for oxygen evolution reaction (OER). In this work, Ni foam supported Co 4 S 3 (Co /NF) was fabricated by a facile one-step approach at room temperature exhibited excellent OER performance in alkaline media. Spe...

Abstract Ultrasound-assisted chalcopyrite leaching has been reported previously, showing a noticeable improvement in kinetics. However, the effect of ultrasound on oxidation kinetics from an electrochemical perspective not addressed. This study examines ultrasonic enhancement sulfuric acid solution both conventional and electrochemistry aspects. Electrochemical techniques, including linear swee...

In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...

A novel triphenylamine (TPA) based donor-π-acceptor (D-π-A) dye is synthesized and its optical electrochemical properties are examined by UV-Vis absorption spectroscopy cyclic voltammetry methods, respectively. The D-π-A plays a role as visible light sensitizer to wide bandgap TiO2 photocatalyst. Hydrogen evolution reaction (HER) carried out using sensitized (Dye/TiO2) under irradiation in the ...
