Microparticle Brownian Motion near an Air-Water Interface Governed by Direction-Dependent Boundary Conditions
Stefano Villa, Christophe Blanc, Abdallah Daddi-Moussa-Ider +2
Although the dynamics of colloids in the vicinity of a solid interface has been widely characterized in the past, experimental studies of Brownian diffusion close to an air-water i…
Helfrich-Hurault elastic instabilities driven by geometrical frustration
Christophe Blanc, Guillaume Durey, Randall D. Kamien +3
The Helfrich-Hurault (HH) elastic instability is a well-known mechanism behind patterns that form as a result of strain upon liquid crystal systems with periodic ground states. In…
The Universality of Thermal Transport in Amorphous Nanowires at Low Temperatures
Adib Tavakoli, Christophe Blanc, Hossein Ftouni +4
Thermal transport properties of amorphous materials at low temperatures are governed by the interaction between phonons and localized excitations referred to as tunneling two level…
Reduction of phonon mean free path: from low temperature physics to room temperature applications in thermoelectricity
Olivier Bourgeois, Dimitri Tainoff, Adib Tavakoli +5
It has been proposed for a long time now that the reduction of the thermal conductivity by reducing the phonon mean free path is one of the best way to improve the current performa…
Evidence for the role of normal-state electrons in nanoelectromechanical damping mechanisms at very low temperatures
K. J. Lulla, M. Defoort, C. Blanc +2
We report on experiments performed at low temperatures on aluminum covered silicon nanoelectromechanical resonators. The substantial difference observed between the mechanical diss…
Nanoscale phase-engineering of thermal transport with a Josephson heat modulator
Antonio Fornieri, Christophe Blanc, Riccardo Bosisio +2
Macroscopic quantum phase coherence has one of its pivotal expressions in the Josephson effect [1], which manifests itself both in charge [2] and energy transport [3-5]. The abilit…
The thermal conductivity of silicon nitride membranes is not sensitive to stress
Hossein Ftouni, Christophe Blanc, Dimitri Tainoff +6
We have measured the thermal properties of suspended membranes from 10 K to 300 K for two amplitudes of internal stress (about 0.1 GPa and 1 GPa) and for two different thicknesses…
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…
Orientational order of carbon nanotube guests in a nematic host suspension of colloidal viral rods
Nicolas Puech, Matthew Dennison, Christophe Blanc +5
In order to investigate the coupling between the degrees of alignment of elongated particles in binary nematic dispersions, surfactant stabilized single-wall carbon nanotubes (CNTs…
Phonon Heat Conduction in Corrugated Silicon Nanowires Below the Casimir Limit
Christophe Blanc, Ali Rajabpour, Sebastian Volz +2
The thermal conductance of straight and corrugated monocrystalline silicon nanowires has been measured between 0.3 K and 5 K. The difference in the thermal transport between corrug…
Behavior of colloidal particles at an air/nematic liquid crystal interface
M. A. Gharbi, M. Nobili, M. In +4
We examine the behavior of spherical silica particles trapped at an air-nematic liquid crystal interface. When a strong normal anchoring is imposed, the beads spontaneously form va…
