Inversion in the temperature coefficient of the optical path length close to the glass transition temperature in tellurite glasses
(American Institute of Physics (AIP), 2009-06-22)
In this study, thermal lens spectrometry was applied to determine the thermo-optical properties of fragile tellurite glasses as a function of temperature, close to the glass transition region. The results showed an inversion ...

Study of the glass transition temperature of as-s glasses for the fabrication of chalcogenide optical fibers
(2013-09-01)
Values of glass transition temperature (Tg) and of linear expansion coefficient (α) for Asx S100-x glasses were measured in the range of concentrations 35 × 42. Because of the importance of the glass formation region 35 × 42 ...

Glass Transition Temperature of Saccharide Aqueous Solutions Estimated with the Free Volume/Percolation Model
(American Chemical Society, 2016-05)
The glass transition temperature of trehalose, sucrose, glucose, and fructose aqueous solutions has been predicted as a function of the water content by using the free volume/percolation model (FVPM). This model only ...
Is ergodicity in an oxide glass ionic conductor a matter of time?
(Elsevier Science, 2015-03)
From the results of molecular dynamic simulations of lithium metasilicate glass - at temperatures above and below their transition temperature (Tg ) - we propose a simple graphical representation to search for the broken ...
Glass transition temperature of hard chairside reline materials after post-polymerisation treatments
(Wiley-Blackwell, 2010-09-01)
Objective:This study evaluated the effect of post-polymerisation treatments on the glass transition temperature (T(g)) of five hard chairside reline materials (Duraliner II-D, Kooliner-K, New Truliner-N, Ufi Gel hard-U and ...

Lead-cadmium fluorogermanate glasses and transparent glassceramics. Spectroscopy and structure
(2006-12-01)
In Lead-cadmium fluorogermanate glasses (PbF2-CdF 2-PbGeO3) the addition of metal fluorides to the base PbGeO3 glass leads to a decrease of the glass transition temperature (Tg) and to an enhancement of the ionic conductivity ...
