Beyond Viscosity: Saliva‐Driven Oral Processing of Commercial Dysphagia Foods Through Rheology, Tribology, and Mucoadhesion

Journal of Food Quality, Volume 2026, Issue 1, 2026.
Designing safe and acceptable foods for individuals with dysphagia requires understanding oral processing beyond viscosity‐based descriptors. Saliva plays a central role in bolus behavior by modulating lubrication, friction, and food–mucosa interactions. In this study, commercially available soft‐solid and gel‐like dysphagia‐oriented foods (pasta‐based

Squeezing a lubricant with exponential pressure dependence of viscosity: Resolution of a hydrodynamic paradox

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.
