Inelastic light scattering has been also extensively used to study the vibrational properties of fractal systems silica aerogels, with their porosity extending on a wide range of sizes, are very nice examples of fractal systems. The peculiar vibrational dynamics of these systems, with spatially localized vibrational modes, is at the origin of the exttemely low measured thermal conductivity. [Pg.776]

Liquid-vapor phase transitions of confined fluids were extensively studied both by experimental and computer simulation methods. In experiments, the phase transitions of confined fluids appear as a rapid change in the mass adsorbed along adsorption isotherms, isochores, and isobars or as heat capacity peaks, maxima in light scattering intensity, etc. (see Refs. [28, 278] for review). A sharp vapor-liquid phase transition was experimentally observed in various porous media ordered mesoporous sifica materials, which contain non-interconnected uniform cylindrical pores with radii Rp from 10 A to more than 110 A [279-287], porous glasses that contain interconnected cylindrical pores with pore radii of about 10 to 10 A [288-293], silica aerogels with disordered structure and wide distribution of pore sizes from 10 to 10" A [294-297], porous carbon [288], carbon nanotubes [298], etc. [Pg.92]

The aerogel is transparent, though it does scatter blue light, giving it a hazy appearance. [Pg.550]
