Universal behavior of internal friction in glasses below T : anharmonicity vs relaxation
Jacques Pelous, Claire Levelut
Comparison of the internal friction at hypersonic frequencies between a few K and the glass transition temperature Tg for various glasses brings out general features. At low temper…
Influence of fictive temperature and composition of silica glass on anomalous elastic behaviour
R Le Parc, C Levelut, J Pelous +2
In order to point out the influence of thermal history (fictive temperature) and OH content on the elastic properties of silica glass, we have performed high resolution in situ Bri…
Dynamic sound attenuation at hypersonic frequencies in silica glass
Claire Levelut, Rozenn Le Parc, Jacques Pelous
In order to clarify the origin of the dominant processes responsible for the acoustic attenuation of phonons, which is a much debatted topic, we present Bril louin scattering exper…
Small Angle Neutron Scattering of Aerogels: Simulations and Experiments
Anwar Hasmy, Marie Foret, Eric Anglaret +3
A numerical simulation of silica aerogels is performed using diffusion-limited cluster-cluster aggregation of spheres inside a cubic box (with periodic boundary conditions). The vo…
