This study was conducted by Gabriel Pérez-Ángel at @cinvestav, Ramón Castañeda-Priego at @UdeGuanajuato, and colleagues at those institutions.

By evaluating effective interactions between colloids, this study disentangles the many-body components of depletion forces and shows how they affect the contact attraction strength as a function of size ratios and the concentration of large colloids. 🔗 go.aps.org/4uZ6pxi

Alexander Goltsev and Sergey Dorogovtsev at @UnivAveiro authored the paper.

Researchers introduce a method for computing and measuring the susceptibility of arbitrary random undirected and directed networks and show that a strong increase of susceptibility is an early warning signal for approaching the percolation point. 🔗 go.aps.org/49c9TnU

M.A. Shishkin and E.S. Pikina at the Landau Institute for Theoretical Physics authored the paper.

All stable vesicle configurations of deflated lipid vesicles are metastable in a uniaxial extensional flow, according to a study that investigates the elastic properties and shape dynamics of deflated vesicles. Check it out: go.aps.org/49aqqbR
