Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

FeCoNiCuPt High‐Entropy Alloy as a Robust Catalytic Shield Against Polysulfide Shuttling in Li–S Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Efficient catalytic materials are vital for addressing the polysulfide shuttle and sluggish redox kinetics in lithium–sulfur batteries. Herein, we report a facile sugar‐blowing method to prepare porous carbon‐supported FeCoNiCuPt high‐entropy alloy (HEA) nanospheres with abundant lattice defects in a single crystalline phase.

A Dual‐Strategy of Iodine Doping and Electrolyte Additive Enabling Fast Reaction Kinetics and Robust Interface for Li‐Se Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Lithium‐selenium (Li‐Se) batteries have attracted considerable attention due to their high theoretical specific capacity and the intrinsically good electronic conductivity of selenium. Nevertheless, low active‐material utilization, parasitic side reactions, and sluggish reaction kinetics hinder their practical application.

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.
