Revealing the Pulmonary Surfactant Corona on Silica Nano-particles by Cryo-Transmission Electron Microscopy
Fanny Mousseau, Evdokia K. Oikonomou, Annie Vacher +3
When inhaled nanoparticles (NPs) deposit in alveoli, they transit through the pulmonary surfactant (PS), a biofluid made of proteins and phospholipidic vesicles. They acquire a cor…
Nanoparticle-lipid interaction: Job scattering plots to differentiate vesicle aggregation from supported lipid bilayer formation
F. Mousseau, E. K. Oikonomou, V. Baldim +2
The impact of nanomaterials on lung fluids or on the plasma membrane of living cells has prompted researchers to examine the interactions between nanoparticles and lipid vesicles.…
Supported pulmonary surfactant bilayers on silica nanoparticles: Formulation, stability and impact on lung epithelial cells
F. Mousseau, C. Puisney, S. Mornet +5
Studies have shown that following exposure to particulate matter, the ultrafine fraction (< 100 nm) may deposit along the respiratory tract down to the alveolar region. To assess t…
Simultaneous concentration and velocity maps in particle suspensions under shear from rheo-ultrasonic imaging
Brice Saint-Michel, Hugues Bodiguel, Steven Meeker +1
We extend a previously developed ultrafast ultrasonic technique [Gallot et al., Rev. Sci. Instrum. 84, 045107 (2013)] to concentration field measurements in non-Brownian particle s…
Collective thermoelectrophoresis of charged colloids
Arghya Majee, Alois Würger
Thermally driven colloidal transport is, to a large extent, due to the thermoelectric or Seebeck effect of the charged solution.We show that, contrary to the generally adopted sing…
Thermocharge of a hot spot in an electrolyte solution
Arghya Majee, Alois Wüurger
We discuss the thermoelectric properties of a locally heated micron-size volume in an electrolyte solution. We find that such a hot spot carries a net charge Q which, for an excess…
Transport in Charged Colloids Driven by Thermoelectricity
Alois Würger
We study the thermal diffusion coefficient DT of a charged colloid in a temperature gradient, and find that it is to a large extent determined by the thermoelectric response of the…
Light-induced pitch transitions in photosensitive cholesteric liquid crystals: Effects of anchoring energy
Tetiana N. Orlova, Roman I. Iegorov, Alexei D. Kiselev
We experimentally study how the cholesteric pitch, , depends on the equilibrium one, , in planar liquid crystal (LC) cells with both strong and semistrong anchoring conditi…
Nematic droplets in aqueous dispersions of carbon nanotubes
Nicolas Puech, Eric Grelet, Philippe Poulin +2
Aqueous dispersions of exfoliated, bile-salt stabilized single-wall carbon nanotubes exhibit a first order transition to a nematic liquid-crystalline phase. The nematic phase prese…
Undulation instabilities in the meniscus of smectic membranes
J. C. Loudet, P. V. Dolganov, P. Patrício +2
Using optical microscopy, phase shifting interferometry and atomic force microscopy, we demonstrate the existence of undulated structures in the meniscus of ferroelectric smectic-C…
A kinetic theory of plastic flow in soft glassy materials
Lyderic Bocquet, Annie Colin, Armand Ajdari
A kinetic model for the elasto-plastic dynamics of a flowing jammed material is proposed, which takes the form of a non-local -- Boltzmann-like -- kinetic equation for the stress d…
Thermophoresis of charged colloidal particles
S. Fayolle, T. Bickel, A. Würger
Thermally induced particle flow in a charged colloidal suspension is studied in a fluid-mechanical approach. The force density acting on the charged boundary layer is derived in de…
Light-driven liquid crystalline nonlinear oscillator under optical periodic forcing
Dmitry O. Krimer, Etienne Brasselet
An all-optically driven strategy to govern a liquid crystalline collective molecular nonlinear oscillator is discussed. It does not require external feedbacks of any kind while the…
Hindered mobility of a particle near a soft interface
Thomas Bickel
The translational motion of a solid sphere near a deformable fluid interface is studied in the low Reynolds number regime. In this problem, the fluid flow driven by the sphere is d…
Brownian motion near a liquid-like membrane
Thomas Bickel
The dynamics of a tracer molecule near a fluid membrane is investigated, with particular emphasis given to the interplay between the instantaneous position of the particle and memb…
Droplet detachment and bead formation in visco-elastic fluids
C. Wagner, Y. Amarouchene, D. Bonn +1
The presence of a very small amount of high molecular weight polymer significantly delays the pinch-off singularity of a drop of water falling from a faucet, and leads to the forma…
Helical Ribbons as Isometric Textures
M. -F. Achard, M. Kleman, Yu. A. Nastishin +1
Deformations that conserve the parallelism and the distances --between layers, in smectic phases; between columns, in columnar phases-- are commonplace in liquid crystals. The resu…
Textural Analysis of a Mesophase with Banana Shaped Molecules
Yu. A. Nastishin, M. F. Achard, H. T. Nguyen +1
Observed under the polarizing microscope, the B7bis phase in the banana compound D14F3 [J.P. Bedel et al, Liq. Cryst., 27, 1411 (2000)] displays two types of textures of defects, n…
Electric-field induced capillary interaction of charged particles at a polar interface
Lionel Foret, Alois Würger
We study the electric-field induced capillary interaction of charged particles at a polar interface. The algebraic tails of the electrostatic pressure of each charge results in a d…
