In this study, we describe experimental efforts to decipher the role of ZnCo2O4 nanoflakes (ZCO-NFs) for selective enhancement of voltammetric responses of screen-printed electrode (SPE) toward redox species system. The ZCO-NFs sample was characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and UV–vis spe...

In the green alga Chlamydomonas reinhardtii, hydrogen production is catalyzed via the [FeFe]-hydrogenases HydA1 and HydA2. The electrons required for the catalysis are transferred from ferredoxin (FDX) towards the hydrogenases. In the light, ferredoxin receives its electrons from photosystem I (PSI) so that H-2 production becomes a fully light-driv...

The heme synthase AhbD catalyzes the last step of the siroheme-dependent heme biosynthesis pathway, which is operative in archaea and sulfate-reducing bacteria. The AhbD-catalyzed reaction consists of the oxidative decarboxylation of two propionate side chains of iron-coproporphyrin III to the corresponding vinyl groups of heme b. AhbD is a Radical...

This study explores the mechanisms bacteria use to transfer electrons outside the cytosol, a fundamental process involved in energy metabolism and environmental interactions. Central to this process is a phenomenon known as flavinylation, where a flavin molecule—a compound related to vitamin B2—is covalently attached to proteins, to enable electron...

Oxygenic photosynthesis, the process that converts light energy into chemical energy, is traditionally associated with the absorption of visible light by chlorophyll molecules. However, recent studies have revealed a growing number of organisms capable of using far-red light (700–800 nm) to drive oxygenic photosynthesis. This phenomenon challenges ...

Multi-photon reduction (MPR) based on femtosecond laser makes rapid prototyping and molding in micro-nano scale feasible, but is limited in material selectivity due to lack of the understanding of the reaction mechanism in MPR process. In this paper, additively manufacturing of complex silver-based patterns through MPR is demonstrated. The effects ...

Abstract Encapsulating Fe 3 C in carbon layers has emerged as an innovative strategy for protecting Fe 3 C while preserving its high oxygen reduction activity. However, fundamental questions persist regarding the active sites of encapsulated Fe 3 C due to the restricted accessibility of oxygen molecules to the metal sites. Herein, the intrinsic ele...

NADPH oxidases (NOX) are transmembrane proteins, widely spread in eukaryotes and prokaryotes, that produce reactive oxygen species (ROS). Eukaryotes use the ROS products for innate immune defense and signaling in critical (patho)physiological processes. Despite the recent structures of human NOX isoforms, the activation of electron transfer remains...

Disproportionation and comproportionation reactions have become routinely proposed events in modern synthetic endevours that use nickel catalysts. This new found appreciation from practitioners in the field for these electron transfer reactions has largely stemmed from our improved understanding of catalytic reactions. These studies have shown evid...
