Hydrodynamic interaction of a self-propelling particle with a wall: Comparison between an active Janus particle and a squirmer model

Zaiyi Shen, Alois Würger, Juho S. Lintuvuori

Using lattice Boltzmann simulations we study the hydrodynamics of an active spherical particle near a no-slip wall. We develop a computational model for an active Janus particle, b…

Steady Microfluidic Measurements of Mutual Diffusion Coefficients of Liquid Binary Mixtures

Anne Bouchaudy, Charles Loussert, Jean-Baptiste Salmon

We present a microfluidic method leading to accurate measurements of the mutual diffusion coefficient of a liquid binary mixture over the whole solute concentration range in a sing…

Humidity-insensitive water evaporation from molecular complex fluids

Jean-Baptiste Salmon, Frédéric Doumenc, Béatrice Guerrier

We investigated theoretically water evaporation from concentrated supramolecular mixtures, such as solutions of polymers or amphiphilic molecules, using numerical resolutions of a…

Highly Confined Stacks of Graphene Oxide Sheets in Water

Rafael Leite Rubim, Margarida Abrantes Barros, Thomas Missègue +3

Since the discovery of graphene oxide (GO), the most accessible of the precursors of graphene, this material has been widely studied for applications in science and technology. In…

Influence of a dispersion of magnetic and nonmagnetic nanoparticles on the magnetic Fredericksz transition of the liquid crystal 5CB

Ahmed Mouhli, Habib Ayeb, Tahar Othman +7

A long time ago, Brochard and de Gennes predicted the possibility of significantly decreasing the critical magnetic field of the Fredericksz transition (the magnetic Fredericksz th…

Hydrodynamic interactions in DNA thermophoresis

Aboubakry Ly, Aloïs Würger

We theoretically study the molecular-weight dependence of DNA thermophoresis, which arises from mutual advection of the n repeat units of the molecular chain. As a main result we f…

Hydrodynamics defines the stable swimming direction of spherical squirmers in a nematic liquid crystal

Juho S. Lintuvuori, Alois Würger, Kevin Stratford

We present a study of the hydrodynamics of an active particle, a model squirmer, in an envi- ronment with a broken rotational symmetry: a nematic liquid crystal. By combining simul…

Surfactant films in lyotropic lamellar (and related) phases: Fluctuations and interactions

Frédéric Nallet

The analogy between soap films thinning under border capillary suction and lamellar stacks of surfactant bilayers dehydrated by osmotic stress is explored, in particular in the hig…

Fast Diffusion of Long Guest Rods in a Lamellar Phase of Short Host Particles

Laura Alvarez, M. Paul Lettinga, Eric Grelet

We investigate the dynamic behavior of long guest rod-like particles immersed in liquid crystalline phases formed by shorter host rods, tracking both guest and host particles by fl…

Visco-elastic drag forces and crossover from no-slip to slip boundary conditions for flow near air-water interfaces

Abdelhamid Maali, Rodolphe Boisgard, Hamza Chraibi +3

The "free" water surface is generally prone to contamination with surface impurities be they surfactants, particles or other surface active agents. The presence of such impurities…

Nanoscale Seebeck effect at hot metal nanostructures

Aboubakry Ly, Arghya Majee, Alois Würger

We theoretically study the electrolyte Seebeck effect in the vicinity of a heated metal nanostructure, such as the cap of an active Janus colloid in an electrolyte, or gold- coated…
