mLife, Volume 4, Issue 6, Page 681-694, December 2025.Abstract Salinization threatens ecosystem stability by altering microbial diversity and function, yet how salinity influences biodiversity‐ecosystem functioning (BEF) relationships remains unclear. In this study, we constructed artificial microbial communities (5–40 strains) with varying salt tolerance and phylogeny, culturing them across a salinity ...

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.ABSTRACT Introduction Agricultural crops face increasing environmental stresses, such as soil salinity and heavy metal contamination, aggravated by climate change and threatening food security. While PGPRs are eco‐friendly agrochemical substitutes, their efficacy in the field is inconsistent.

Thermal-EHL tribodynamic analysis of a spur-gear pair, using correction factors [PDF]
MATEC Web of ConferencesA thermal-tribodynamic model was developed to study the produced vibrations in a pair of spur gears, considering rough anisotropic tooth surfaces, the use of Newtonian and non-Newtonian lubricants, and friction induced temperature effects. It consists of

Room‐Temperature Collective Quantum Emission Mediated by Wannier–Mott Excitons in CsPbBr3 Nanowires
Small Science, Volume 5, Issue 11, November 2025.Room‐temperature collective quantum emission emerges in partially aligned CsPbBr3 nanowires through spontaneous synchronization of Wannier–Mott excitons. This alignment enables cooperative dipole–dipole interactions that result in coherent photon bursts (N2 × hν), even under ambient conditions.

RESEARCH ON DYNAMIC CHARACTERSITICS OF LINE CONTACT FRICTION PAIRS UNDER THERMAL EHL STATE
Jixie qiangdu, 2023 The line contact elasto-hydrodynamic lubrication (EHL) phenomenon generally exists in key parts of mechanical systems e. g. bearings, gears, the lubricant oil film between the contact interfaces acts as a spring and damper, and the frictional heat ...
