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

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 …

We present detailed studies of ionic conductivity in several polymerized ionic liquids
(PolyILs) with different size of mobile ions. Presented analysis revealed that charge diffusion …

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 …

Focusing on metallic glasses as model systems, we review the features and mechanisms of
the β-relaxations, which are intrinsic and universal to supercooled liquids and glasses, and …

The present work studies the mechanisms controlling the energy barrier for ion hop** in
conducting polymers. Polymer electrolytes usually show Arrhenius-like temperature …

Conductivity in polymer electrolytes has been generally discussed with the assumption that
the segmental motions control charge transport. However, much less attention has been …

The Johari-Goldstein secondary (β) relaxations are intrinsic features of supercooled liquids
and glasses, and they play a crucial role in several properties of glassy materials. However …

Protic ionic liquids (PILs) are key materials for a wide range of emerging technologies. In
particular, these systems have long been envisioned as promising candidates for fuel cells …

In recent years, there is a growing interest in improving the physicochemical stability of
amorphous pharmaceutical solids due to their very promising applications to manufacture …
