Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

Physical aging is a ubiquitous phenomenon in glassy materials and originates from the fact
that they are generally out-of-equilibrium. Due to the technological and fundamental …

The phenomenology of the glass transition and the associated behavior in the near liquid
and glassy states are detailed, including the cooling rate dependence of the glass transition …

We use x-ray photon correlation spectroscopy to investigate the structural relaxation process
in a metallic glass on the atomic length scale. We report evidence for a dynamical crossover …

The noncrystalline glassy state of matter plays a role in virtually all fields of materials science
and offers complementary properties to those of the crystalline counterpart. The caveat of the …

We investigated the kinetics of enthalpy recovery of several glass-forming polymers at
temperatures significantly below the glass transition temperature (T g) and for aging times …

We review the recent activity aiming to clarify glassy dynamics in nanostructured polymer
glasses, in particular thin films, nanocomposites and nanospheres. Special emphasis is …

The fate of matter when decreasing the temperature at constant pressure is that of passing
from gas to liquid and, subsequently, from liquid to crystal. However, a class of materials can …

Physical ageing is the generic term for irreversible processes in glassy materials resulting
from molecular rearrangements. One formalism for describing such ageing processes …

Still very little is known on the relaxation dynamics of glasses at the microscopic level due to
the lack of experiments and theories. It is commonly believed that glasses are in a dynamical …
