  • Ultrastable glasses: new perspectives for an old problem

    Rodriguez-Tinoco C., Gonzalez-Silveira M., Ramos M.A., Rodriguez-Viejo J. Rivista del Nuovo Cimento; 45 (5): 325 - 406. 2022. 10.1007/s40766-022-00029-y. IF: 3.000

    Ultrastable glasses (mostly prepared from the vapor phase under optimized deposition conditions) represent a unique class of materials with low enthalpies and high kinetic stabilities. These highly stable and dense glasses show unique physicochemical properties, such as high thermal stability, improved mechanical properties or anomalous transitions into the supercooled liquid, offering unprecedented opportunities to understand many aspects of the glassy state. Their improved properties with respect to liquid-cooled glasses also open new prospects to their use in applications where liquid-cooled glasses failed or where not considered as usable materials. In this review article we summarize the state of the art of vapor-deposited (and other) ultrastable glasses with a focus on the mechanism of equilibration, the transformation to the liquid state and the low temperature properties. The review contains information on organic, metallic, polymeric and chalcogenide glasses and an updated list with relevant properties of all materials known today to form a stable glass. © 2022, The Author(s).
