the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...

in this research, polyvinylchloride based composite heterogeneous cation exchange membranes were prepared by the solution casting technique. chitosan-co-iron nickel oxide nanoparticles were utilized as membrane surface modifier to improve the membranes electrochemical properties. the effect of additive nanoparticle concentration in the modifier solution on the properties of composite membranes ...

Abstract The need of quick testing nicotine (NIC) is vital because its hurtful impacts on human. NIC detection has been successfully developed using a novel sensitive simple electrochemical sensor. sensor system based modifying carbon paste electrode (CPE) Ni and Cu nanoparticles to develop the new nickel/copper nanoparticle–modified (NCNMCPE) with low-cost procedure. showed excellent electroca...

Bimetallic nanoparticles comprised of iron and nickel were synthesized, characterized, evaluated to optimize the ideal metal ratio for azo dye removal from water systems. Results show that changing molar caused different rates, as well extent overall elimination water. Lower ratios, Ni 1 Fe xmln...

Surface-enhanced infrared absorption spectroscopy (SEIRAS) is a powerful tool that allows studying the reactivity of protein monolayers at very low concentrations and independent from size. In this study, we probe surface’s morphology electroless gold deposition for optimum enhancement using two different types immobilization adapted to proteins. Independently mode measurement (i.e., transmissi...
