TL;DR: It is demonstrated that the vibrational signal has both high- and low-spatial-resolution components, that the first component can be used to map vibrational features at nanometre-level resolution, and that the second component can been used for analysis carried out with the beam positioned just outside the sample—that is, for ‘aloof’ spectroscopy that largely avoids radiation damage.

TL;DR: The insights gained in a recent molecular dynamics simulation study are applied to create conditions for successful vitrification of metallic liquid germanium and provide micrographic evidence for a rare polyamorphic transition preceding crystallization of the diamond cubic phase.

TL;DR: In this article, the effects of high pressures on the structure of silica glass have been elucidated using high-energy x-ray diffraction up to 43.5 GPa, indicating an initial shrinkage of the tetrahedral units.

TL;DR: In this article, it is shown that the reticulation of chalcogenide glass structure increases continuously until $x=0.4$ following the ''chain crossing model'' and then undergoes a transition toward a lower dimension pyramidal network containing an increasing number of molecular inclusions.

TL;DR: A series of cell assemblies specially designed and implemented for inter-laboratory use are described in this article, including an 8/3, 10/5, 14/8, 18/12, and 25/15 assembly.
