Isolation and Characterization of Human Gut Bacteria Capable of Extracellular Electron Transport by Electrochemical Techniques

Frontiers in Microbiology, 2019
Microorganisms are known to exhibit extracellular electron transfer (EET) in a wide variety of habitats. However, as for the human microbiome which significantly impacts our health, the role and importance of EET has not been widely investigated. In this

Differences in Applied Redox Potential on Cathodes Enrich for Diverse Electrochemically Active Microbial Isolates From a Marine Sediment

Frontiers in Microbiology, 2019
The diversity of microbially mediated redox processes that occur in marine sediments is likely underestimated, especially with respect to the metabolisms that involve solid substrate electron donors or acceptors.

Oxygen In The Mix: Is Oxic Microbial Electrosynthesis A Potential Alternative For Biomass Production?

ChemElectroChem, Volume 11, Issue 20, October 16, 2024.
Oxic microbial electrosynthesis (oMES) enables the conversion of renewable electricity and oxic industrial CO2‐streams into biomass by cultivating aerobic, autotrophic hydrogen‐oxidizing bacteria. This article presents the most promising candidates for oMES, discusses their biomass productivity and energy efficiency, and outlines research gaps to bring

Synergistic Enhancement of Supercapacitors with Cobalt–Copper Bimetal–Organic Framework

Advanced Engineering Materials, Volume 26, Issue 13, July 2024.
Herein, a novel cobalt–copper‐based bimetal–organic framework (CoCu‐MOF) is investigated as a supercapacitor electrode material. The CoCu‐MOF is synthesized by a bottom‐up strategy and displays an excellent specific capacitance, more than twice that of Co‐MOF and four times that of Cu‐MOF.
