Vibrational spectroscopy has continued use as a powerful tool to characterize ionic liquids
since the literature on room temperature molten salts experienced the rapid increase in …

Recent progress in the description of glassy relaxation and aging are reviewed for the wide
class of network-forming materials such as GeO 2, Ge x Se 1− x, silicates (SiO 2–Na 2 O) or …

When a liquid is cooled below its melting temperature, it usually crystallizes. However, if the
quenching rate is fast enough, the system may remain in a disordered state, progressively …

We present a detailed analysis of correlations between fragility and other parameters of
glass-forming systems. The analysis shows the importance of the ratio between the …

We report on a detailed, temperature-dependent, off-resonant Raman scattering study of
glassy and supercooled selenium. Raman spectra in the frequency regime of the first-order …

This article gives an overview of experimental results on dynamics in bulk glass-forming
molecular liquids. Rather than looking for phenomenology that is universal, in the sense that …

The state of polymerization in barium silicate glasses (xBaO·(1-x) SiO 2, 0.28≤ x≤ 0.45)
has been studied by both experiment (Raman, static and MAS 29 Si NMR spectroscopy) and …

The concept of fragility provides a possibility to rank different supercooled liquids on the
basis of the temperature dependence of dynamic and/or thermodynamic quantities. We …

A series of glasses x MgO–(1− x) SiO 2 with compositions from enstatite MgSiO 3 (x= 0.5) to
forsterite Mg 2 SiO 4 (x= 0.667) in mole fraction intervals of x≈ 0.02 have been prepared by …

We present a theory of low-frequency Raman scattering in glasses, based on the concept
that light couples to the elastic strains via spatially fluctuating elasto-optic (Pockels) …
