Enhancing the Cycle Performance of Lithium-Sulfur Batteries by Coating the Separator with a Cation-Selective Polymer Layer.

Lithium-sulfur batteries are believed to possess the feasibility to power electric vehicles in the future ascribed to the competitive energy density. However, soluble polysulfides continuously shuttle between the sulfur electrode and lithium anode across the separator, which dramatically impairs the battery's capacity. Herein, the surface of a polypropylene separator (PP film) is successfully modified with a delicately designed cation-selective polymer layer to suppress the transport of polysulfides.

Anxiety, depression, insomnia, and PTSD among college students after optimizing the COVID-19 response in China.

Background: The number of COVID-19 infections has increased sharply and quickly after optimizing the COVID-19 response in China. In the context of this population-size infection, college students' psychological response is yet to be understood.

Methods: A cross-sectional study was designed to investigate anxiety, depression, insomnia, and post-traumatic stress disorder (PTSD) symptoms among college students from December 31, 2022, to January 7, 2023.

Standardized studies of the oral microbiome: From technology-driven to hypothesis-driven.

The microbiome is in a symbiotic relationship with the host. Among the microbial consortia in the human body, that in the oral cavity is complex. Instead of repeatedly confirming biomarkers of oral and systemic diseases, recent studies have focused on a unified clinical diagnostic standard in microbiology that reduces the heterogeneity caused by individual discrepancies.

Disrupting cannabinoid receptor interacting protein 1 rescues cognitive flexibility in long-term estrogen-deprived female mice.

Hormone therapy (HT) has failed to improve learning and memory in postmenopausal women according to recent clinical studies; however, the reason for failure of HT in improving cognitive performance is unknown. In our research, we found cognitive flexibility was improved by 17β-Estradiol (E2) in mice 1 week after ovariectomy (OVX), but not in mice 3 months after ovariectomy (OVX). Isobaric tags for relative and absolute quantitation (iTRAQ) revealed increased cannabinoid receptor interacting protein 1 (CNRIP1) in E2-treated OVX mice compared with E2-treated OVX mice.

Exploring the Effect of a MnO Coating on the Electrochemical Performance of a LiMnNiCoO Cathode Material.

The effect of electrochemically active MnO as a coating material on the electrochemical properties of a LiMnNiCoO (LTMO) cathode material is explored in this article. The structural analysis indicated that the layered structure of the LTMO was unchanged after the modification with MnO. The morphology inspection demonstrated that the rod-like LTMO particles were encapsulated by a compact coating layer.
