Deciphering the structure-property relations of densified oxide glasses is a problem of
longstanding interest. For example, it is important for understanding the fracture mechanism …

The general availability of third generation synchrotron sources has ushered in a new era of
high pressure research. The crystal structure of materials under compression can now be …

The present study investigates the boron and aluminium speciation of aluminoborosilicate
glasses synthesised under ambient to high-pressure conditions (up to 2.0 GPa) using 11 B …

Glass structure remains puzzling to scientists, especially due to the challenges in
characterizing their structural order beyond the first coordination shell, ie, the so-called …

During the decompression of plastically deformed glasses at room temperature, some
aspects of irreversible densification may be preserved. This densification has been primarily …

Glasses of the K2O–B2O3–GeO2 system were studied by means of Raman and IR
spectroscopy. The density of the samples was measured and the dependence of the molar …

The structures of amorphous materials at extreme pressures can be very different from those
of their crystalline counterparts. Recent nonresonant inelastic scattering experiments on …

Noncrystalline oxides under pressure undergo gradual structural modifications, highlighted
by the formation of a dense noncrystalline network topology. The nature of the densified …

As oxygen may occupy a major volume of oxides, a densification of amorphous oxides
under extreme compression is dominated by reorganization of oxygen during compression …

Densification in glassy networks has traditionally been described in terms of short-range
structures, such as how atoms are coordinated and how the coordination polyhedron is …
