Atomistic origin of structural relaxation in lead metasilicate and lithium disilicate glasses Open
A combination of density measurement, differential scanning calorimetry, refractometry, and Raman and 29 Si nuclear magnetic resonance (NMR) spectroscopy is employed to characterize the evolution of the structure and physical properties of…

Rheology of a sodium‐molybdenum borosilicate melt undergoing phase separation Open
During glass production, phase separation can result in the formation of suspended liquid droplets, which can cause changes in the system rheology. In nuclear waste vitrification context, some new glassy matrices may present this phase sep…

Elemental and cooperative diffusion in a liquid, supercooled liquid and glass resolved Open
The diffusion mechanisms controlling viscous flow, structural relaxation, liquid-liquid phase separation, crystal nucleation, and crystal growth in multicomponent glass-forming liquids are of great interest and relevance in physics, chemis…
