Glass transition of glycerol in the volume-temperature plane.
We assess the relative importance of spatial congestion and lowered temperature in the slowing dynamics of supercooled glycerol near the glass transition. We independently vary both volume V and temperature T by applying high pressure and monitor the dynamics by measuring the dielectric susceptibility. Our results demonstrate that both variables are control variables of comparable importance. H...
متن کاملElectron anions and the glass transition temperature.
Properties of glasses are typically controlled by judicious selection of the glass-forming and glass-modifying constituents. Through an experimental and computational study of the crystalline, molten, and amorphous [Ca12Al14O32](2+) ⋅ (e(-))2, we demonstrate that electron anions in this system behave as glass modifiers that strongly affect solidification dynamics, the glass transition temperatu...

We assess the relative importance of spatial congestion and lowered temperature in the slowing dynamics of supercooled glycerol near the glass transition. We independently vary both volume, V , and temperature, T , by applying high pressure and monitor the dynamics by measuring the dielectric susceptibility. Our results demonstrate that both variables are control variables of comparable importa...
متن کاملOn the Glass Transition Temperature in Covalent Glasses
We give a simple demonstration of the formula relating the glass transition temperature, Tg, to the molar concentration x of a modifier in two types of glasses: binary glasses, whose composition can be denoted by XnYm+xMpYq, with X an element of III-rd or IV -th group (e.g. B, or Si, Ge), while MpYq is an alkali oxide or chalcogenide; next, the network glasses of the type Ax B1−x, e.g. Gex Se1−...
