The dielectric signature of glass density

At present, we are witnessing a renewed interest in the properties of densified glasses prepared by isobaric cooling of a liquid at elevated pressure. As high-pressure densification emerges as a promising approach in the development of glasses with customized features, understanding and controlling their unique properties represent a contemporary scientific and technological goal. The results Read more about The dielectric signature of glass density[…]

The role of thermodynamic stability in the characteristics of the devitrification front of vapour-deposited glasses of toluene

Physical vapour deposition (PVD) has settled in as an alternative method to prepare glasses with significantly enhanced properties, providing new insights into the understanding of glass transition. One of the striking properties of some PVD glasses is their transformation into liquid via a heterogeneous mechanism that initiates at surfaces/interfaces. Here, we use membrane-based fast-scanning nanocalorimetry (104 K s−1) Read more about The role of thermodynamic stability in the characteristics of the devitrification front of vapour-deposited glasses of toluene[…]
