Ethnopharmacological Relevance: Cholestatic liver injury (CLI) is a pathophysiological syndrome characterized by the accumulation of bile acids (BAs), which leads to significant hepatic dysfunction. This condition is frequently associated with disturbances in BAs homeostasis and the induction of oxidative stress. Ribes diacanthum Pall (RDP), a conventional folk medicinal plant, has been employed in Mongolia, the Inner Mongolia region of China, and other areas for the remediation of hepatic disorders.

Here, a quenching strategy was developed to create oxygen vacancies in Cu doped α-MnO. The evolutions of oxygen vacancies were directly followed by means of XRD refinement, EPR and XPS. In combination with DFT calculations and detailed characterizations, evidence is captured that oxygen vacancies not only act as direct sites for the adsorption and activation of gaseous oxygen and toluene, but also accelerate the consumption and replenishment cycle of lattice oxygen species by weakening the strength of metal-oxygen bonds.

In this study, a hydroxylamine (HA)-enhanced magnetic spinel catalyst CuFeO-activated peroxymonosulfate (PMS) system (CuFeO/PMS/HA) was constructed to degrade Sulfamethoxazole (SMX). Results from experiments and theoretical calculations indicated that active species generation mechanism involved the direct activation of PMS by HA, the redox cycles acceleration on the surface of CuFeO by HA, and the synergistic action of the low valence Fe and Cu species in CuFeO for PMS activation. The efficacy of other organic pollutants removal was further validated in bio-treated landfill leachate through removal performance and toxicity assessment.

Biomass starvation is common in biological wastewater treatment. As a social trait of microbial community, how quorum sensing (QS) regulated bacterial trade-off through interactions after starvation remains unclear. This study deciphered the mechanism of anaerobic ammonium oxidation (anammox) consortia in response to starvation, including reducing extracellular electron transfer (EET), adenosine 5'-triphosphate (ATP) content and amino acid metabolism.

ConspectusLithium-ion batteries (LIBs) based on graphite anodes are a widely used state-of-the-art battery technology, but their energy density is approaching theoretical limits, prompting interest in lithium-metal batteries (LMBs) that can achieve higher energy density. In addition, the limited availability of lithium reserves raises supply concerns; therefore, research on postlithium metal batteries is underway. A major issue with these metal anodes, including lithium, is dendritic formation and insufficient reversibility, which leads to safety risks due to short circuits and the use of flammable electrolytes.
