Experimental study of diffusiophoresis in a cellular flow
Florence Raynal, Menghua Zhao, Romain Volk
In this article, we study experimentally the dispersion of colloids in a two-dimensional, time independent, Rayleigh-Bénard flow in the presence of salt gradients. Due to the addit…
Sliding of liquid droplets on thin viscoelastic soft layers
Menghua Zhao, Julien Dervaux, Tetsuharu Narita +3
Soft substrates are deformed by liquid-vapor surface tension upon contact with liquid droplets, forming the well-known wetting ridge. This ridge dynamically propagates with the mov…
Condensation effect and transport on Alumina porous membranes
Fernanda R. Leivas, Menghua Zhao, Aymeric Allemand +4
Understanding the adsorption of water and characterizing the water film formed within nanostructures are essential for advancements in fields such as nanofluidics, water purificati…
Anomalous near-equilibrium capillary rise
Menghua Zhao, Aktaruzzaman Al Hossain, Carlos E. Colosqui +1
We report and rationalize the observation of a crossover from the classical Lucas-Washburn dynamics to a long-lived anomalously slow regime for capillary rise in simple glass tubes…
Self-Assembly of Nanoparticles from Evaporating Sessile Droplets: Fresh Look into the Role of Particle/Substrate Interaction
N Bridonneau, M Zhao, N Battaglini +6
We studied the dependence of solid deposit shape obtained by free drying of sessile drops on the particles concentration and Derjaguin-Landau-Verwey-Overbeek (DLVO) particle/substr…
Spreading of granular suspensions on a solid surface
Menghua Zhao, Alice Pelosse, Mathieu Oléron +3
We examine the spreading of a suspension of non-Brownian spheres suspended in a Newtonian liquid on a solid substrate. We show that the spreading dynamics is well described by the…
