Infections and Human Intestinal Microbiota.

() is a common pathogen that can cause many human diseases, such as skin infection, food poisoning, endocarditis, and sepsis. These diseases can be minor infections or life-threatening, requiring complex medical management resulting in substantial healthcare costs. Meanwhile, as the critically ignored "organ," the intestinal microbiome greatly impacts physiological health, not only in gastrointestinal diseases but also in disorders beyond the gut.

Correlating the valence state of a Cu-based electrocatalyst for CO reduction to C.

In this study, a facile ligand-protected strategy for preparing Cu@CuO and CuO nanoparticles is presented. The electrocatalyst efficacy of the CuO variant, particularly for CO reduction to multi-carbon products (C), is significant, boasting faradaic efficiencies (FEs) surpassing 85% and a current density peak at 340 mA cm. This exceptional performance markedly exceeds that of the Cu@CuO electrocatalyst.
