Summary: In this study, the effects of substituting functional groups and molecular conjugate structures on the electrochemical properties of nitroaromatic derivatives as organic cathodes for rechargeable lithium-ion batteries were investigated. It was found that the redox potential of nitroaromatic cathodes can be adjusted by introducing different electronically inducible functional groups, and the cyclic life can be prolonged by introducing hydrophilic groups. Additionally, the electronic conductivity and electrochemical kinetics of nitroaromatics can be increased significantly with the introduction of extended p-conjugated structures.

Summary: This article investigates the electrochemical performance of amorphous sodium iron carbonophosphate in both organic and ionic-liquid based electrolytes. The results show that using ionic-liquids instead of organic electrolytes leads to superior cycling performance at room temperature and high temperature, with nearly fade-free electrochemical cells. The dense and ionically conductive protective film composed of anion-reduced moieties is responsible for the excellent high-temperature performance of amorphous sodium iron carbonophosphate with ionic-liquids.

Summary: This review summarizes the structures, biochemical properties, and mechanisms of two major biological sources of ethylene, the ethylene-forming enzyme (EFE) and 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase (ACCO). Despite catalyzing distinct chemical reactions, EFE and ACCO are related in sequence and structure, and both enzymes require Fe(ii) for their activity. Advances in our understanding of EFE have clarified how this enzyme catalyzes its dual reactions, while drawing on the published mechanistic studies of ACCO and noting the parallels between this enzyme and EFE, a novel reaction mechanism for ACCO is proposed.

Summary: Enzymes with the nickel-pincer nucleotide (NPN) cofactor catalyze C2 racemization or epimerization reactions of alpha-hydroxyacid substrates. LarB initiates synthesis of the NPN cofactor from nicotinic acid adenine dinucleotide (NaAD) by carboxylating the pyridinium ring C5 and hydrolyzing phosphoanhydride. LarB uses carbon dioxide as the substrate for carboxylation and activates water for hydrolytic attack on the C5-carboxylated-NaAD, enhancing reactivity. Structural studies show LarB has a unique N-terminal domain and a C-terminal domain homologous to PurE, with four active sites located at subunit interfaces. The complex of LarB with NAD* reveals a covalent adduct between Cys221 and NAD*, resulting in a boat-shaped dearomatized pyridine ring.
