Poly(lactic acid)-based Nanocomposite for Construction of Efficient Bilirubin Oxidase-Based Biocathodes and Stable Biofuel Cells

International Journal of Electrochemical Science, 2014
A modification of electrode surfaces with dispersions of carbon black and consequent enzyme adsorption has been recognized as an efficient technique for construction of biofuel cells (BFCs). To achieve this, typically fluorinated polymers with a negative

Dynamics of cathode-associated microbial communities and metabolite profiles in a glycerol-fed bioelectrochemical system [PDF]

, 2013
Electrical current can be used to supply reducing power to microbial metabolism. This phenomenon is typically studied in pure cultures with added redox mediators to transfer charge.

Understanding the Catalytic Determinant role of Diaphorase‐Like Subunit in Formate Dehydrogenases via Redox Couples

Advanced Science, EarlyView.
A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

Engineering and Applications of fungal laccases for organic synthesis [PDF]

, 2008
Laccases are multi-copper containing oxidases (EC 1.10.3.2), widely distributed in fungi, higher plants and bacteria. Laccase catalyses the oxidation of phenols, polyphenols and anilines by one-electron abstraction, with the concomitant reduction of ...

Impact of Crystallinity and Ni–Fe Composition on the Oxygen Evolution Performance of NixFe1‐xO Electrocatalysts in Anion Exchange Membrane Water Electrolysis

ChemSusChem, Volume 19, Issue 10, 27 May 2026.
Expensive platinum group metals (PGMs) are used to enhance the anodic oxygen evolution reaction (OER) kinetics, and they represent a real bottleneck in the commercialization of anion exchange membrane water electrolyzers (AEMWEs). Therefore, we present a scalable and economical homogeneous precipitation method to synthesize NixFe1‐xO nanoparticles with
