The description of kinetics of physical aging, namely the slow evolution of a glass
thermodynamic state toward equilibrium, generally relies on the exclusive role of the main α …

Mineral acids in the atmosphere breakdown on the action of oxygen and release acid gases
into atmosphere causing acid rain, which can chemically weather materials. We …

Polymers of intrinsic microporosity (PIMs) are promising candidates for the active layer in
gas separation membranes due to their high permeability and reasonable permselectivity …

An out-of-equilibrium simulation method for tracking the time evolution of glassy systems (or
any other systems that can be described by hopping dynamics over a network of discrete …

The effect of physical aging of the partially miscible blend of polycarbonate: polystyrene (PC:
PS) at temperatures near the glass transition temperature (T g) of the PS was studied as a …

Shape memory polymers (SMPs) maintain a temporary shape after pre‐straining, wherein
the polymer chains are constrained in a non‐equilibrium thermodynamic state. Physical …

The effects of temperature, pressure, and imposed strain on the structural transition
pathways of glassy atactic polystyrene (aPS) are studied for a wide range of conditions. By …

Transition pathways on the energy landscape of atactic polystyrene (aPS) glassy specimens
are probed below its glass-transition temperature. Each of these transitions is considered an …

Physical aging is an ubiquitous phenomenon in glasses. It takes place on liquids previously
cooled down below their melting temperature and subsequently further cooled below their …

This study focuses on isothermal charging and discharging currents in polystyrene (PS). It is
a well known fact that the discharging current is almost the mirror symmetry of the charging …
