When monochromatic radiation νo, is incident on a system (gas, solid, liquid, glass, whether
colored or transparent) most of the radiation is transmitted through the system without …

The structure of glasses and the melts from which they are formed is intrinsically disordered,
making their structural characterization difficult. Whilst the structure of solid minerals can be …

It is widely known that the low-temperature physical properties, such as the heat capacity
and thermal conductivity, of a disordered amorphous solid are markedly different from those …

Four-wave mixing (FWM) processes, based on third-order nonlinear light–matter
interactions, can combine ultrafast time resolution with energy and wavevector selectivity …

The term 'vitrified'is used to describe the glassy appearance of some charcoals recovered in
the archaeological record. It has been generally considered that this phenomenon is a result …

We have investigated a series of glasses and melts along the GeO2–SiO2 join using insitu
Raman spectroscopy. The results for both the glasses and melts are consistent with a …

We demonstrate a correlation between how an IR-active vibrational mode responds to
temperature changes and how it responds to crystallinity differences. Infrared (IR) …

Viscosity and structure of Na/K tectosilicate glasses containing 75 and 83mol% of SiO2 have
been investigated. Viscosity increases non-linearly when K+ ions substitute Na+ ions in …

Titania represents an important compound for property modifications in the widespread
family of soda lime silicate glasses. In particular, such titania-containing glasses offer …

When amorphous materials are compressed their structures are expected to change in
response to densification. In some cases, the changes in amorphous structure can be …
