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[…]

Relaxation dynamics of glasses along a wide stability and temperature range

Up to this moment, the dynamics of glasses have been measured in a very short temperature range, limited by their time-scale. At low temperatures, the dynamics of glasses are too slow to be measured and at too high temperatures, the glass relax into the equilibrium supercooled state before being possible to extract any information by Read more about Relaxation dynamics of glasses along a wide stability and temperature range[…]
