3D tracking of #microswimmers shows where they accumulate inside a droplet :) #activematter read our new Physical Review Fluids invited article here journals.aps.org/prfluids/abstr… or here: arxiv.org/pdf/2210.03228… Institute of Physics Physics of Fluids @ UTwente with Detlef Lohse & @AlvaroGuM
One does not need superheated surfaces for the Leidenfrost effect to occur: fizzy water and a superhydrophobic surface are enough, as shown by Gareth McKinley & Philippe Bourrianne in their very nice Phys. Today article physicstoday.scitation.org/doi/full/10.10… (and their references therein).
Dès lundi, les conférences expérimentales reprennent du service ! Ne manquez pas la prochaine sur "le son des bulles" avec P. Marmottant, B. Dollet (LIPHY, Université Grenoble Alpes ), J. Pierre (Institut Jean le Rond d’Alembert, Sorbonne Université ) #confexp ESPGG espgg.org/Le-son-des-bul…
Excited to release our latest work, led by Hongbo Zhao in collaboration with our friend Andrej Košmrlj! In this preprint (arxiv.org/abs/2301.12345), we study how chemotactic active matter phase separates—and find many cool surprises. 🦠🚀🔬 Tweetorial follows... [1/8]
Bacteria play marbles! In Physical Review E we show that swimming bacteria induce the clustering of micrometric beads, yielding giant clusters up to several millimeters. This process follows a self-similar dynamics analogous to Ostwald ripening. doi.org/10.1103/PhysRe…
Nice work from Phil Bayly, Susan Dutcher and collaborators, using acoustic trapping as an alternative way to confine microswimmers so the can be imaged at high res, including flagellar synchrony in the case of #chlamydomonas. pnas.org/doi/epdf/10.10…
🌟 Hot off the press! New in @PNASnews: the mechanics of prey capture in carnivorous plants Nepenthes 🌱🐜 Exciting collaboration with Alain Goriely, Chris Thorogood & Derek Moulton Oxford Mathematics University of Oxford Botanic Garden and Arboretum! A thread with all the juicy details 🍽️ 🧵 pnas.org/doi/10.1073/pn…
Well done Rebecca Rebecca Poon on the publication of your first-author paper! In doi.org/10.1103/PhysRe… we study how tiny baby corals (well coral larvae to be precise) self propel using #cilia, and deduce the nature of ciliary coordination on the surface of the #coral
