FeNiCo|MnGaO Heterostructure Nanoparticles as Bifunctional Electrocatalyst for Zn-Air Batteries.

Driven by the pressing demand for stable energy systems, zinc-air batteries (ZABs) have emerged as crucial energy storage solutions. However, the quest for cost-effective catalysts to enhance vital oxygen evolution and reduction reactions remains challenging. FeNiCo|MnGaO heterostructure nanoparticles on carbon nanotubes (CNTs) are synthesized using liquid-phase reduction and H calcination approach.

Implications of gut microbiota dysbiosis and fecal metabolite changes in psychologically stressed mice.

Introduction: Psychological stress can induce affective disorders. Gut microbiota plays a vital role in emotional function regulation; however, the association between gut microbiota and psychological stress is poorly understood. We investigated effects of psychological stress on the gut microbiome and fecal metabolites and assessed the relationship between affective disorder behavior and altered fecal microbiota.

A study on Chinese ancient jades with mercury alteration unearthed from Lizhou'ao Tomb.

"Alteration" geologically refers to chemical composition and/or structural changes of minerals under the influences of hydrothermal fluids, surface water, seawater, or other environmental conditions. In this paper, we use the word "alteration" to refer to chemical component and structural changes in jade artifacts caused by human activity and natural weathering, which is different from the term in geology. "Mercury alteration", a kind of black alteration related to Hg, is unique among the several types of alteration that occur in Chinese ancient jades.
