Dynamic Light Scattering Study of Concentrated W/O Microemulsions

Light beating spectroscopy experiments were performed on concentrated W/O microemulsions located in the vicinity of the gel phase on the phase diagram. New results are reported: the most interesting feature is the non-exponential behaviour of the self-correlation function g (1)(K, τ) of the scattered field. The initial decay rate of g (1)(K, τ) is not directly proportional to K 2; whereas the long time decay is found fairly exponential.

VH spectra from liquid and supercooled salol

Abstract VH spectra of light scattered by salol have been measured over a wide temperature range. A hydrodynamic model using two relaxing processes fits accurately the line shapes in the full viscosity range.

Some thermodynamic properties of liquid xenon

Abstract Using new sound velocity measurements and accurate PVT data, we have calculated the thermodynamical properties of liquid xenon from the triple point to fifteen degrees below the critical temperature. Within the experimental errors, the calculated quantities agree with the theoretical values and allow us to test the significant structure theory.

Critical perturbation of Xe dynamics at high pressure

We present xenon dynamics experimental results obtained by light scattering techniques along the isotherm T 1 = 293.26 K for pressures up to 130. atm. We find two differents behaviours for the fluids properties. The sound speed and the Landau-Placzek intensity ratio follows the hydrodynamic theory of Mountain provided that the numerical simulation were effectued with reliable thermodynamic data. The sound absorption and the thermal relaxation are perturbated by the proximity of the critical point in a pressure range 40 atm < P < 90 atm but outside this domain that dynamics follows the hydrodynamical model.
