Abstract The nanostructured cyclically refreshable liquid amalgam film silver-based electrode (R-AgLAFE) was applied to study of the Bi(III) process in presence 2-thiocytosine and selected ionic surfactants. application voltammetrictechniques (SWV, CV, DC), as well electrochemical impedance spectroscopy (EIS) allowed determination kinetic which turn, defined catalytic effect also their correlat...

A theoretical model is developed to stimulate electro-kinetic transfer through peristaltic movement in a micro-channel. The effect of variable viscosity and wall properties are considered. long wavelength small Reynolds number approximations supposed simplify the governing formulas. Debye-Huckel linearization also utilized. perturbation technique utilized solve non-linear equations. graphical o...

recently, a variety of soils contaminated with heavy metals e.g. cr (vi), have been found in industrial sites. such soil contamination is widely distributed in the world and has now become a serious issue for environment. hexavalent chromium, cr (vi), which is known to be carcinogenic and mutagenic to living organisms, has been utilized for leather tanning, electroplating and in other industrie...

Nano-graphene/polymer composites can function as pressure induced electro-switches, at concentrations around their conductivity percolation threshold. Close to the critical point, dependence of electron tunneling through polymer barrier separating nano-graphene's results from competition among shortening length and increase polymer's polarizability. Such switching behavior was recently observed...

In this study, boroxine derivative (K₂[B₃O₃F₄OH]) was tested as an inhibitor of horseradish peroxidase (HRP) by spectrophotometric and electrochemical methods. The activity of horseradish peroxidase was first studied under steady-state kinetic conditions by a spectrophotometric method which required the use of guaiacol as a second substrate to measure guaiacol peroxidation. The results of this ...
