Experimental Observations Of Nonequilibrium Concentration Fluctuations In A
Light-scattering experiments in solutions of polystyrene with mass-averaged molecular weight M w 96,400 dissolved in toluene have been performed in our laboratory. The polystyrene solution was contained in a horizontal layer located between an upper and lower plate. The optical arrangement was similar to the one used earlier for measuring nonequilibrium fluctuations in liquid mixtures of toluene and n-hexane 9 . Because of the dependence of the nonequilibrium enhancement of the fluctuations on...

The SANS data were collected on the W. C. Koehler 30m SANS facility 12 at the Oak Ridge National Laboratory ORNL via a 64 x 64 cm2area detector with cell size 1 cm2and aneutronwavelength, X 4.75 A AX X 0.006 . Thedetectorwasplaced atvarious sample-detector distances and the data were corrected for instrumental backgrounds and detector efficiency on a cell-by-cell basis, prior to radial averaging, to give a Q-range of 0.005 lt Q 4nX-1 sin 0 lt 0.05 A-1, where 29 is the scattering angle. The net...
