Two-dimensional (2D) melting transitions have been observed in two freely expanding colloidal monolayer crystals formed from 1.01 μm polystyrene microspheres in an aqueous suspension between parallel optical flats, and with expansion rates differing

A light-scattering investigation of Brownian motion in the critical mixture nitroethane-isooctane is reported, along with a theory to explain the results. The diffusion constant of $0.3\ensuremath{-}\ensuremath{\mu}$ Teflon particles was measured by

We report careful measurements of the Rayleigh linewidth of light scattered from a critical binary fluid. Laser heating and multiple-scattering effects are accounted for. With use of independent data for xi and the shear viscosity, a parameter-free f

Intensity autocorrelation measurements of the diffusion constant of lysozyme molecules in aqueous solutions as a function of applied magnetic field reveal no evidence of the cooperative behaviour proposed by Ahmed, Calderwood, Frohlich and Smith (197

We describe photon autocorrelation measurements of the Rayleigh linewidth in thin binary liquid films near the critical point. Measurements were made on four films of thickness 13.1, 4.1, 2.1, and 0.5 ..mu..m. The films were formed by trapping and se

The first measurements are reported of the Rayleigh linewidth of binary liquid films near the critical point for which the correlation length is comparable to the film thickness. The present data are in good agreement with the predictions of renormal

A two-dimensional melting transition has been observed in a freely expanding colloidal monolayer lattice formed of 1.01-\ensuremath{\mu}m polystyrene microspheres in an aqueous suspension between two parallel optical flats. The correlation functions

Rayleigh linewidth data gathered at small scattering angles on critical-mixture films of thickness 2L are found to collapse about a single universal curve, GAMMA((Kxi/sup eff/), where GAMMA((x) is the 3D reduced Rayleigh linewidth function, and xi/su

The authors present a new experimental technique for producing model two-dimensional systems subject to external fields of arbitrary symmetry and variable coupling strength. An aqueous suspension of colloidal microspheres is confined to a single laye
