Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro

Journal of Applied Toxicology, Volume 46, Issue 10, Page 3437-3445, October 2026.
ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

The Filler Network Index: A Viscosity‐Independent Rheological Criterion for Quantifying Silica Architecture in Unvulcanized Rubber Compounds

SPE Polymers, Volume 7, Issue 4, October 2026.
SEM images of unmodified (U30) and TESPT‐grafted (U30‐SCA) silica compounds show that pre‐grafting eliminates agglomerates. Stress relaxation data fitted with a constrained five‐element Weichert model give discrete relaxation times (τ1$$ {\tau}_1 $$‐τ5$$ {\tau}_5 $$), both reduced by grafting. Their ratio, the Filler Network Index (FNI = τ1$$ {\tau}_1 $

SPH Modelling of Hydrodynamic Lubrication along Rough Surfaces

Lubricants, 2019
Rough and textured surfaces are of paramount importance for lubrication, both in nature and in technology. While surface roughness relevantly influences both friction and wear, artificial surface texturing improves the performance of slider bearings as ...

Tactic Behaviors in Asymmetric Pacman Particles

Small, Volume 22, Issue 56, 8 October 2026.
The swimming behavior of TiO2 Pacman particles exhibits different modes depending on the fuel and illumination conditions. However, the behavior of these intrinsically asymmetric particles is still not well understood, and here we present a first approach to modeling their dynamics. Furthermore, we investigate their fundamental responses to some of the
