With a facile solvothermal technique, Ssynthesis and application of Fe3O4@PPy–CuIIcomposite microspheres in the carbon ionic liquid matrix have been reported as highly sensitive sensors for voltammetric determination of Carbamazepine (CBZ). The morphology, crystal phase and structure of synthesized The nanocomposite structure was confirmed by routine methods such as transmission electron micros...

abstract wenner direct contact method is a method of estimating apparent electrical conductivity (eca) of agricultural soils in situ. this method can be affected by factors such as quality of electrodes in contact with soil, type of employed electric current, moisture content, clay content and compaction of soil. in this research, the effect of electrode type (rod and plate) and electric curren...

The influences of the electrode/ionic liquids interfaces on charge transfer kinetics are addressed with example oxidation chromocene at a single crystal Ag(111) electrode. We considered three different imidazolium-based room temperature ionic (RTILs) alkyl chains lengths but common anion. standard rate constants k° extracted from cyclic voltammograms (CVs) by analyzing peak potential variations...

a modified electrode was prepared by modification of the carbon paste electrode (cpe) with graphene nano-sheets. the fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (ga) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. the graphene modified cpe had a lower overvoltage and enhanced electrical current respect to...
