Li, W. B. ; Zhang, K. J. ; Sengers, Jan V. ; Gammon, R. W. ; Ortiz de Zárate Leira, José María | American Physical Society | 1998-12-21We have performed small-angle Rayleigh light-scattering measurements in polymer solutions under various externally applied temperature gradients. Our experiments confirm the existence of an enhancement of the concentration fluctuations. The none[...]texto impreso
Li, W. B. ; Zhang, K. J. ; Sengers, Jan V. ; Gammon, R. W. ; Ortiz de Zárate Leira, José María | American Institute of Physics | 2000-05-22We have performed light-scattering measurements in dilute and semidilute polymer solutions of polystyrene in toluene when subjected to stationary temperature gradients. Five solutions with concentrations below and one solution with a concentrati[...]
