Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels
Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Elastohydrodynamic lubrication of coated finite line contacts [PDF]
, 2017 In this work, a finite element-based model is presented that simulates elastohydrodynamic lubrication in coated finite line contacts. Using this model, the film thickness and pressure distributions, between a straight roller with rounded edges on a ...

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 ...

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 9, September 2025.Abstract It is known that viscosity of most fluids, in particular lubricants, increases with pressure. The most typical dependence used in lubrication applications is a simple exponential law (Barus law). This behavior is of great importance for lubricated systems in highly loaded mechanical parts, such as rolling bearings, gears, or cam followers.
