Samuel Amanuel from the Department of Physics and Astronomy (in collaboration with Sanford Sternstein of RPI) presented their paper on “Enthalpic Relaxation of Silica-Polyvinyl Acetate Nanocomposites” at the American Physical Society meeting in New Orleans, March 10-14, 2008. Their thermal measurements on glassy polyvinyl acetate revealed that nano silica particles reduced the extent of relaxations in the polymer. This could imply that nano particle can alter the ageing mechanism of polymers and improve their shelf life.

The annual March Meeting of the APS is the largest physics conference of the year. This year’s meeting was held in New Orleans, LA, with more than 7,000 paper presented by speakers from all over the world.
