Laponite is a synthetic disc-shaped crystalline colloid that is widely used to modify rheological properties of liquids in applications such as cosmetics, paints, and inks so that understanding its flow properties and aging behavior is of considerabl

The liquid–glass transition in the disaccharide sugar trehalose mixed with small amounts of water was studied with calorimetry, photon correlation spectroscopy, Brillouin scattering, dielectric spectroscopy, and rheology measurements. Trehalose is

Light scattering experiments were performed on two inorganic glass-forming liquids: ZnCl2 and 0.8TeO2-0.2Na2O up to 650°C. In ZnCl2, vertical-vertical and vertical-horizontal spectra were analysed with viscoelastic theory using either a Debye or a C

The molecular glass former trimethylheptane was studied by calorimetric, dielectric, ultrasonic, neutron scattering, Brillouin scattering, and depolarized light-scattering techniques. The molecular structure appears to be nearly spherical optically a

We review the dynamics of supercooled liquids approaching the liquid-glass transition, starting with the conventional generalized hydrodynamics formulation. Empirical models for the memory function are discussed, as are empirical models for the self-

A liquid-glass transition was observed experimentally in a new system, an oil-in-water emulsion. Dynamic light scattering was employed to obtain the intermediate scattering function f(q,t) for a range of volume fractions f and scattering vectors q. T

Pattern formation at the solid-liquid interface of a growing crystal was studied in directional solidification using a perturbation technique. We analyzed both experimentally and numerically the stability range and dynamical selection of cellular arr

Depolarized light scattering susceptibility spectra of orthoterphenyl (OTP) were analyzed using the idealized and extended versions of mode coupling theory (MCT). The extended MCT fits were combined with KWW fits to the α peaks to provide combined

Stability of a uniformly spaced dendritic array against a spatial period doubling instability was studied through UV thermal perturbations of every other dendrite tip. We observed that above a critical pulling speed the array is stable against these
