Insights into Homogeneous Bulk Boron Doping at the Tetrahedral Site of NCM811 Cathode Materials: Structure Stabilization by Inductive Effect on TM-O-B Bonds.

Rechargeable lithium-ion batteries (LIBs) are critical for enabling sustainable energy storage. The capacity of cathode materials is a major limiting factor in the LIB performance, and doping has emerged as an effective strategy for enhancing the electrochemical properties of nickel-rich layered oxides such as NCM811. In this study, boron is homogeneously incorporated into the tetrahedral site of NCM811 through co-precipitation, leading to an inductive effect on transition metal (TM)-O-B bonds that delayed structural collapse and reduced oxygen release.

The Paussus (Scaphipaussus) lanxangensis species group of Indomalayan ant nest beetles (Coleoptera, Carabidae, Paussinae, Paussini) with description of a new species.

The new species Paussus agatae sp. nov. could not easily be allocated to an established subgenus or even species group.

Tailoring superstructure units for improved oxygen redox activity in Li-rich layered oxide battery's positive electrodes.

The high-voltage oxygen redox activity of Li-rich layered oxides enables additional capacity beyond conventional transition metal (TM) redox contributions and drives the development of positive electrode active materials in secondary Li-based batteries. However, Li-rich layered oxides often face voltage decay during battery operation. In particular, although Li-rich positive electrode active materials with a high nickel content demonstrate improved voltage stability, they suffer from poor discharge capacity.

Urbanization, loneliness and mental health model - A cross-sectional network analysis with a representative sample.

With increasing urbanization, more people are exposed to mental health risk factors stemming from the urban social or physical environment. However, research on the relationship between urbanization and mental health is lacking. This cross-sectional study aimed to explore the relationships of the physical environment (spatial cohesion and urban environment) and social factors (neighborhood cohesion) with mental health (stress, anxiety and depression symptoms) and physical health and the mediating role of loneliness based on the proposed theoretical model.
