Extracellular electron transfer (EET) is a type of microbial respiration that enables electron transfer between microbial cells and extracellular solid materials, including naturally-occurring metal compounds and artificial electrodes. Microorganisms harboring EET abilities have received considerable attention for their various biotechnological applications, in addition to their contribution to...

Herein, we extend our "combined electrochemical-frustrated Lewis pair" approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical-frustrated Lewis pair (FLP) system involving the B(C6 F5 )3 /[HB(C6 F5 )3 ]- redox couple exhibits a strong surface electrocatalytic effect at Pt electrodes. Using a combination of kinetic competition s...

A study was carried out to characterize Ni-Co-PVC and Ni-Cu-PVC composite materials prepared by mechanical alloying technique (MAT) using SEM, EDS and electrochemical test. Composite materials were prepared by mixing together 95% of metal powder (Ni+Co or Ni+Cu) with 5% PVC. PVC was used as a binder and tetrahydrofuran (THF) was used as a solvent in composite material preparation. Based on the ...

Powering microbes with electrical energy to produce valuable chemicals such as biofuels has recently gained traction as a biosustainable strategy to reduce our dependence on oil. Microbial electrosynthesis (MES) is one of the bioelectrochemical approaches developed in the last decade that could have critical impact on the current methods of chemical synthesis. MES is a process in which electroa...

Reports that globular proteins could enhance the interference blocking ability of the PPD (poly(o-phenylenediamine) layer used as a permselective barrier in biosensor design, prompted this study where a variety of modifying agents were incorporated into PPD during its electrosynthesis on Pt-Ir electrodes. Trapped molecules, including fibrous proteins and β-cyclodextrin, altered the polymer/modi...

In this work, we have synthesized and discussed the results of electrosynthesis metal-polymer nanocomposites gold. Nanocoatings were made on pure iron steel electrodes by combining process electropolymerization 1-vinyl-1.2.4-triazole with crotonic acid cathodic deposition Using UV, IR atomic absorption spectroscopies, X-ray phase analysis, as well thermogravimetric elemental analyses, structure...
