Enhancing Potassium-Ion Storage through Nanostructure Engineering and Ion-Doped: A Case Study of Cu-Doped CoSe with Yolk-Shell Structure.

Fabricating transition metal selenide (TMSe) anode materials with rapid K diffusion and high-rate performance is crucial for the advancement of potassium-ion batteries (PIBs), yet it remains a challenge. In this study, a Cu-doped CoSe@N-doped carbon anode with an optimal concentration of Cu-doped and yolk-shell structure (denoted as Cu-CoSe@NC-2) is developed to enhance the reaction kinetics and cycling life. The Cu-doped modulates the electronic structure of the CoSe interface, improves the diffusion and adsorption of K, and further promotes the charge transport efficiency, as demonstrated by theoretical calculations and experimental results.

Acceleration of Ethanol Metabolism by a Patented Isolated Alcohol Degradation Protein (ADP) on Acute Alcohol Consumption.

Alcoholic beverages are among the most widely enjoyed leisure drinks around the world. However, irresponsible drinking habits can have detrimental effects on human health. Therefore, exploring strategies to alleviate discomfort following alcohol consumption would be beneficial for individuals who inevitably need to consume alcohol.

Unraveling the atomic-scale mechanism of interfacial alkali ion close packing in nano glassy fibers driven by CO-mediated attraction.

The poor alkali resistance of nano-glassy fiber (NGF) hinders its application in aggressive alkaline environments like cement and alkaline wastewater. This study introduced a potential strategy to enhance the alkali resistance of NGF based on the distinct atomic-scale interactions between CO molecules and NGF ions at high temperatures. The short-range structure in the NGF-CO system was elucidated through the pair distribution functions and coordination numbers of ion-oxygen pairs and second-nearest-neighbor ion-ion pairs.

Delayed school start time is associated with better sleep, mental health, and life satisfaction among residential high-school students: a prospective study.

This study examined the longer-term individual- and school-level changes in students 7 months after a 1-hour delay in school start time (SST). Two cohorts of grade 11 students (N = 227; 60.8% female, age = 17.
