TL;DR: A range of particle-based and glassy systems show universal features of the onset of plasticity and a universal yield strain, and a microscopic structural quantity, “softness,” designed by machine learning to be maximally predictive of rearrangements is links structure to plasticity in disordered solids.

TL;DR: Cubuk et al. as mentioned in this paper link structure to plasticity in disordered solids via a microscopic structural quantity, "softness," designed by machine learning to be maximally predictive of rearrangements.

TL;DR: In this article, the dewetting instability in ultra-thin molecular glass films was studied and it was shown that these films exhibit a sharp transition from glassy solid to liquid-like behavior when the thickness is reduced below 30 nm.

TL;DR: The Tg of confined PS, which interacts weakly with SiO2 NPs, significantly increases with decreasing pore size such that for the two molecular weights of PS studied the Tg increases by up to 50 K in 11 nm NP packings, while Tg is close to the bulk Tg in 100 nmNP packings.

TL;DR: In this paper, the authors measured the effective viscosity of organic glass films by monitoring the dewetting kinetics and showed that the apparent activation barrier for rearrangement decreases sharply in films thinner than 30 nm.
