Cobalt has great biological effects on human beings and also other living organisms, hence its determination is very important. In this regard, a novel coated graphite electrode was designed for determination of Co2+ ions by exploiting 6-chloro-11- azabenzo[a]phenothiazin-5-one as a neutral ion carrier, for the first time. The foremost function was witnessed from the membrane composition of PVC...

A novel approach for bulk synthesis of lithium-intercalated graphene sheets through the reduction of exfoliated graphene oxide in liquid ammonia and lithium metal is reported. It is demonstrated here that as-synthesized lithiated graphite oxide sheets (Li-RGO) can be directly used as an electrode material in lithium batteries. The electrochemical studies on Li-RGO electrodes show a significant ...

Here we report on the design and study of a biofuel cell consisting of a glucose oxidase-based anode (Aspergillus niger) and a laccasebased cathode (Trametes versicolor) using osmium-based redox polymers as mediators of the biocatalysts’ electron transfer at graphite electrode surfaces. The graphite electrodes of the device are modified with the deposition and immobilization of the appropriate ...

The possibility of providing the acetogenic microorganism Sporomusa ovata with electrons delivered directly to the cells with a graphite electrode for the reduction of carbon dioxide to organic compounds was investigated. Biofilms of S. ovata growing on graphite cathode surfaces consumed electrons with the reduction of carbon dioxide to acetate and small amounts of 2-oxobutyrate. Electrons appe...

This paper presents a Single-chamber Microbial Fuel Cell (SMFC) design by utilizing soil as substrate with two sets of electrode combinations, which are graphite-activated carbon and copper-zinc different sizes. It was found that graphite activated produced greater power density compared to copper zinc. Moreover, it observed the cloth bigger surface area 51cm2, resulted in higher 904mW/m2. To f...

Undesirable electrochemical phenomena at electrode|solution interfaces during ohmic heating can be avoided or effectively inhibited by choosing an appropriate electrode material. We attempted to understand the electrochemical behavior of four types of electrode materials: titanium, stainless steel, platinized-titanium, and graphite at pH 3.5, 5.0, and 6.5. The electrodes were examined comparati...

The redox reactions of quinones can be used in electrical energy storage systems. Biopolymers are one the important sources for due to sustainability and low cost. In this work, biomass materials that contain a large fraction potential quinone groups directly fabricate biomass/graphite hybrid material electrodes, without extraction or separation active components from other elements. Among thes...

The electrochemical behavior of lithium-ion battery electrode materials is often studied in the so-called ‘lithium half-cell configuration’, which tested an cell with a lithium metal acting as both counter and reference electrode. However, performance batteries affected by two electrodes composing battery. Therefore, order to understand under conditions representative commercial applications, i...

Silicon is a promising negative electrode material with high specific capacity, which desirable for commercial lithium-ion batteries. It often blended graphite to form composite anode extend lifetime, however, the electrochemical interactions between silicon and have not been fully investigated. Here, an model developed validated batteries silicon/graphite anode. The continuum-level can reprodu...
