Fragility and glass transition temperature of polymer confined under isobaric and isochoric conditions

22-05-2013 | Chuan Zhang; Rodney D. Priestley, Soft Matter, 2013

It is now well established that the glass transition temperature (Tg) of polymers can deviate substantially from the bulk with nanoscale confinement. Understanding the impact of confinement on the Tg of polymers is important but it does not provide information about the temperature dependence ...

Prediction of the concentration dependence of the surface tension and density of salt solutions: atomistic simulations with polarizable and nonpolarizable models.

22-05-2013 | Jean Claude Neyt; Aurelie Wender; Véronique Lachet; Aziz Ghoufi; Patrice Malfreyt, Physical Chemistry Chemical Physics, 2013

Molecular simulations using polarizable and nonpolarizable models for water and ions are carried out to predict the dependence of the surface tension on salt concentration. The polarizable water and ion models are based on the classical Drude oscillators. The temperature dependence of the ...
