Latex particle thermophoresis in polar solvents
Article Abstract:
A theoretical model of the thermophoresis of latex particles in polar solvents, which is based on the thermophoresis of polymer chains partitioned between the emulsion droplet and the surrounding solvent is presented and can be used for obtaining the expressions for thermophoretic mobility (TM) of the particles. It was seen that the dimensionless parameter had greater value than or equal to unity for polystyrene in the polar solvents like water and acetonitrile and the TM of polystyrene in these systems could be compared to the TM of polystyrene in nonpolar solvents.

Experimental evidence of thermophoresis of non-Brownian particles in pure liquids and estimation of their thermophoretic mobility
Article Abstract:
The first experimental evidence that noncollodial particles exhibit a thermophoretic migration when placed in a temperature gradient is provided by observing the retention of micro-sized porous spherical particles. A method of determination of the thermophoretic mobility is developed which relies on the dependence of the amount of retained particles on the duration of the initial stop-flow immediately after sample introduction.

Nanoconfinement revealed in degradation and relaxation studies of two structurally different polystyrene-clay systems
Article Abstract:
Various degradation and relaxation studies of two structurally different polystyrene (PS)-clay systems are conducted to analyze its nanoconfinement. Both the systems are found to yield large values of activation energy for thermal degradation, as well as glass transition processes.
