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 ...

A study of thermal effects in EHL rheology and friction using infrared microscopy
Tribology International, 2020 Abstract Infrared microscopy is used to obtain through-thickness oil temperature measurements from EHL contacts between different surface materials (steel, silicon nitride and zirconia) for the lubricants Santotrac 50 and PAO4. The measurement technique was first adapted to overcome focussing issues due to the partially transparent zirconia surface ...

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.

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 ...

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.

Thermal Characteristic Analysis and Experimental Study of a Spindle-Bearing System
Entropy, 2016 In this paper, a thermo-mechanical coupling analysis model of the spindle-bearing system based on Hertz’s contact theory and a point contact non-Newtonian thermal elastohydrodynamic lubrication (EHL) theory are developed.

An Advanced Approach for the Analysis of the Rotor Dynamics of a Ball Bearing Turbocharger
Engineering ProceedingsTurbochargers operate under highly transient conditions, which impose significant mechanical and thermal loads on their rotating components. When supported by ball bearings combined with squeeze film dampers, the rotor system exhibits complex nonlinear ...
