Psychological stress catalyses free radical–mediated activation of coagulation in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study provides the first in vivo evidence that acute psychological stress triggers systemic free radical formation and prothrombotic remodelling of blood clot microstructure. By inducing stress in healthy participants, we observed a significant increase in oxidative stress (A•−), a shortening of the intrinsic pathway of ...

Analysis of Branching Mechanisms for Post‐Transition State Bifurcation Reactions Using Molecular Dynamics Simulations

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 11, June 5, 2026.
Systematic molecular dynamics simulations on 18 intramolecular cycloadditions reveal two distinct post‐transition‐state bifurcation regimes—distinguished by the position of the valley–ridge transition (VRT) point along the reaction path—whose branching fractions are quantitatively predicted by a two‐parameter descriptor combining the VRT lateral offset

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

open access: yesAIChE Journal, Volume 72, Issue 6, June 2026.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as
