Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure

Vapour deposited ultrastable glasses have gained much attention since its discovery in 2007 by the group of Mark Ediger. By physical vapour deposition, at proper deposition conditions, it is possible to obtain, in just few minutes, glasses with a thermodynamic stability that rivals the stability of glasses naturally aged for millions of years, i.e. ambers.

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[…]
