Interested in living/active matter? I will be giving a @RoySocChem "desktop seminar" webinar on August 5, describing our recent work studying bacterial growth in complex fluids, along with my friend & intellectual hero Kate Stebe (U. Penn)!

In their new Letter, Deblais et al. use experiments, theory, and simulations to study the very first moments of drop coalescence. In drop-drop and drop-bath configurations, the authors show the key role played by surrounding gas and van der Waals forces

Many thanks for highlighting our work @PhysRevFluids! 🙏👍😊
📢 PRFluids Editors' suggestion: Stafford & @MatarLab from @ImperialChemEng explore the regimes of thin liquid films on rapidly spinning disks. Through experiments and simulations, they reveal the transition from 2D spirals to complex 3D waves. More @ go.aps.org/3XhhfAy

📢 in @JFluidMech (bit.ly/3QuxMgE) on how viscosity alters drop-impact forces. With Bin Zhang, Cunjing Lv, & @detlef_lohse. The first and second force peaks emerge from distinct flow mechanisms—one at impact, another at take-off. @poftwente bit.ly/4gUvD8P
Very sad to hear of the passing of a giant of fluid mechanics.
Prof. Acrivos leaves behind an unparalleled legacy: an incredible body of work and a family tree of students that will maintain his exacting standards.
May Andy’s spirit rest in peace.
