Abstract:
\nWe discuss how solids can be made slippery for liquids, and more specifically for water drops. This situation of obvious practical interest (think about the numerous cases where we would like to avoid materials to be wet by a rain) also rises beautiful basic questions – and specifically, how to avoid that drops stick to their substrate? and how can we minimize the friction of these drops when they are mobile? We’ll try to answer these questions by considering three possibilities – highly-hydrophobic solids, hot substrates, and lubricated materials.<\/p>\n
Bio: After his M.Sc. and one year in the French Navy (where he scrutinized the radioactive cloud of Chernobyl), David Qu\u00e9r\u00e9 obtained a Ph.D. from Universit\u00e9 Pierre et Marie Curie, Paris. He continued with a position at the Physics Labs at Coll\u00e8ge de France (until 2006) and at the Laboratoire de Physique et M\u00e9canique des Milieux H\u00e9t\u00e9rog\u00e8nes at ESPCI (since). In 2006, he also became a Professor at \u00c9cole Polytechnique (Departments of Physics and Mechanics). He is engaged in experimental research in Soft Matter Physics and Fluid Mechanics, with a strong interest in interfacial hydrodynamics (drops, films, bubbles, coating, wicking) as well as in aerodynamics, morphogenesis and biomimetics, all topics on which he coworked with about 35 PhD students (the greatest chance in his scientific life). He is or was a scientific advisor at Saint-Gobain (Paris), Procter & Gamble (Cincinnati) and Nikon\/Essilor (Tokyo), a coeditor at Europhysics Letters and an associate editor at Physical Review Fluids. He received the 2001 Ernest-Dechelle Prize of the Acad\u00e9mie des Sciences (Paris), the 2014 Silver Medal of CNRS (France), and the 2021 Fluid Dynamics Prize from the APS.<\/p>\n","protected":false},"excerpt":{"rendered":"
