TL;DR: Stretchable superhydrophobicity was possible because of the monolithic nature of the hierarchical wrinkles as well as partial preservation of nanoscale structures under stretching.

TL;DR: In this article, the authors characterized the time dependence of the frequency-dependent dielectric susceptibility of glycerol following quenches to low temperature and found that most of the susceptibility change with time occurs within one equilibrium relaxation time after the quench, and their results do not support the presence of a significant ultraslow component to the equilibration of the glycerric response.

TL;DR: Using x-ray tomography, it is found that long chains pack into a low-density structure whose mechanical rigidity is mainly provided by the backbone, and close similarities are uncovered between the packing of chains and the glass transition in polymers.

TL;DR: If the amplitude of the vibrations is increased, the properties of low-amplitude vibrations in dry unconsolidated granular materials are investigated and nonlinearity near the point at which the authors first see hysteretic behavior is observed.

TL;DR: In this article, the excess low-frequency normal modes for two widely used models of glasses are studied at zero temperature, and the onset frequencies for anomalous modes for both systems agree well with predictions of a variational argument, which is based on analyzing the vibrational energy originating from the excess contacts per particle over the minimum number needed for mechanical stability.
