Pressure effects on electrical conduction in glasses

TLDR
In this paper, the compatibility of electronic and ionic conduction processes in glasses such as Ag-doped As-Se glasses and Bi2O3B 2O3 glass was discussed from these aspects.
Abstract
Electrical conduction in various inorganic glasses was studied as a function of hydrostatic pressure up to 2000 atm and phenomenologically classified into electronic, ionic and mixed types. In electronically conducting glasses such as AsSe chalcogenide glasses and Fe2O3P2O5 glass, the conduction is enhanced by application of pressure. On the other hand in ionically conducting glass such as Na2OB2O3 glass, the conduction is suppressed through the concept of an activation volume. The compatibility of electronic and ionic conduction processes in glasses such as Ag-doped AsSe glasses and Bi2O3B2O3 glass, which have more complex conduction processes, was discussed from these aspects.

Reversible dehydration of trehalose and anhydrobiosis: from solution state to an exotic crystal?

TL;DR: In this article, a critical analysis of solution thermodynamics is made in order to scrutinize trehalose properties often called "anomalous" and to check the consistency of literature results, with a special emphasis on the transformations involving the newly identified anhydrous crystalline form of α,α-trehalose, TREα.

Broadband dielectric relaxation study at ambient and elevated pressure of molecular dynamics of pharmaceutical: indomethacin.

TL;DR: Broadband dielectric measurements on the pharmaceutical indomethacin (IMC) and the possibility of preparation of the amorphous state with higher density than by cooling of the liquid are discussed, and it is found that the fragility of IMC decreases with increasing pressure.

Simple band model for amorphous semiconducting alloys

TL;DR: Amorphous covalent alloys particularly of group-IV, -V, and -VI elements are readily formed over broad ranges of composition and have been described as low-mobility electronic intrinsic semiconductors with a temperature-activated electrical conductivity σ = σ 0×exp(-ΔE/kT) which sometimes extends well into the molten state as discussed by the authors.
