Activation energy spectrum for relaxation and polyamorphism in an ultra-viscous metallic glass former
Isabella Gallino, Daniele Cangialosi, Zach Evenson +4
Many glass-formers exhibit phase transitions between two distinct liquid states. For some metallic glass-formers, the liquid-liquid transition is experimentally found in the superc…
Reaching the ideal glass transition by aging polymer films
Virginie M. Boucher, Daniele Cangialosi, Angel Alegria +1
Searching for the ideal glass transition, we exploit the ability of glassy polymer films to explore low energy states in remarkably short time scales. We use 30 nm thick polystyren…
Clarifying the controversy of the Tg depression in polystyrene thin films
V. M. Boucher, D. Cangialosi, A. Alegría +1
The glass transition temperature () of polymer thin films has been a subject of controversy in the last two decades. (Pseudo)thermodynamic determinations of generally su…
A thermodynamic approach to the fragility of glass-forming polymers
D. Cangialosi, A. Alegria, J. Colmenero
We have connected the dynamic fragility, namely the rapidity of the relaxation time increase upon temperature reduction, to the excess entropy and heat capacity of a large number o…
