Frictional Characteristics of Atomically-Thin Sheets
TL;DR: Using friction force microscopy, the nanoscale frictional characteristics of atomically thin sheets of graphene, molybdenum disulfide, niobium diselenide, and hexagonal boron nitride are compared to those of their bulk counterparts, suggesting that the trend arises from the thinner sheets’ increased susceptibility to out-of-plane elastic deformation.

Micromechanical and microstructure characterization of BaO-Sm2O3–5TiO2 ceramic with addition of Al2O3
TL;DR: In this article, the main phase is Ba3.99Sm9.34Ti18O54 of orthorhombic tungsten bronze structure, and the secondary phase was Ba1.18Al1.90Ti6.09O16 of tetragonal structure, which has two types of grains: grey and cubic, and white and quasi-rectangular.

Stress Corrosion and Static Fatigue of Glass
Sheldon M. Wiederhorn,L. H. Bolz +1 more
TL;DR: In this article, the authors used fracture mechanics techniques to measure the crack velocities in water as a function of applied stress intensity factor and temperature, and apparent activation energies for crack motion were obtained.

A Molecular Mechanism for Stress Corrosion in Vitreous Silica
TL;DR: In this paper, the authors studied stress corrosion in vitreous silica exposed to water and several nonaqueous environments; environments which enhance stress-corrosion crack growth in silica contain active groups with electron donor sites on one end and proton donor sites at the other.

Evidence for internal resistive barriers in a crystal of the giant dielectric constant material: CaCu3Ti4O12
TL;DR: In this paper, complex impedance spectra were obtained on a crystal of CaCu3Ti4O12 (CCTO) from 289 to 456 K. As in the case of ceramic CCTO, these spectra can be interpreted as arising from a conducting material containing insulating barriers.
