Equilibration, the complex set of molecular rearrangements leading to more stable states, is
usually dominated by density fluctuations, occurring through the structural (α-) relaxation …

We employ fast scanning calorimetry to monitor the isothermal aging kinetics in glassy
polymers, complemented with measurements on other glasses. Apart from following the time …

In this article, we investigate the structural relaxation of lithium silicate glass during
isothermal physical aging by monitoring the temporal evolution of its refractive index and …

The paradigmatic view on the transformation of a supercooled liquid into a glass, so‐called
vitrification or glass transition, and the subsequent time evolution of the non‐equilibrium …

Polymer glasses attain thermodynamic equilibrium owing to structural relaxation at various
length scales. Herein, calorimetry experiments were conducted to trace the macroscopic …

Large-amplitude thermal excursions imposed on deeply supercooled liquids modulate the
nonlinear time evolution of their structural rearrangements. The consequent aftereffects are …

A high-resolution, temperature oscillation-based probe of physical aging in complex systems
is introduced. The Fourier analysis of the measured responses allows one to extract high …

This study investigates the effect of α-relaxation induced by physical aging due to a down-
jump in fictive temperature (T f) on the alkali ion hopping dynamics and the resulting ionic …

In a recent paper, Di Lisio et al.[J. Chem. Phys. 159, 064505 (2023)] analyzed a series of
temperature down-jumps using the single-parameter aging (SPA) ansatz combined with a …

We studied the physical aging of glycerol in response to upward temperature steps of
amplitude ranging from 0.3 to 18 K. This was done using a specially designed experimental …
