A theoretical perspective on the glass transition and nonequilibrium phenomena in disordered materials
theoretical perspective glass transition nonequilibrium phenomena disordered materials
2010/11/22
We provide a theoretical perspective on the glass transition in molecular liquids at thermal equi-librium, on the spatially heterogeneous and aging dynamics of disordered materials, and on the rheolog...
Understanding spin glass transition as a dynamic phenomenon
spin glass transition dynamic phenomenon
2010/11/19
We synthesize large-area graphene via atmospheric-pressure (AP) chemical vapor deposition
(CVD) on copper, and transfer to SiO2 wafers. In contrast to low-pressure (LP) CVD on copper,
optical contra...
Viscosity and Glass Transition in Amorphous Oxides
Glass Transition solid-state Amorphous Oxides
2009/9/4
An overview is given of amorphous oxide materials viscosity and glass-liquid transition phenomena. The viscosity is a continuous function of temperature, whereas the glass-liquid transition is accompa...
On the influence of the supermolecular structure on structural relaxation in the glass transition zone: free volume approach
polymers free volume a relaxation
2009/2/6
The idea of two miscellaneous amorphous fractions in polymer is discussed. The effect of free volumeon the segmental relaxation behaviour is examined for a wide range of polymers. The orientation of t...
Glass transition temperature of thermoplastic starches
thermoplastic starch glass transition temperature differential scanning calorimetry extrusion
2008/11/18
Thermoplastic starch was produced by mixing potato starch and glycerol in a single screw extruder. The glass transition temperatures of the materials obtained were measured by differential scanning ca...
Glass Transition, Water Plasticization, and Lactose Crystallization in Skim Milk Powder
lactose crystallization milk powder glass transition relative humidity
2008/3/28
Effects of water content, storage time, and glass transition (physical state) on lactose crystallization and the resultant crystal forms in skim milk powder were investigated. Samples of freeze-dried ...
The Influence of Polysaccharides on the Glass Transition in Frozen Sucrose Solutions and Ice Cream
glass transition ice cream stabilizers thermomechanical analysis
2008/3/17
The objective of this study was to describe further the mechanism by which polysaccharide stabilizers contribute to stability of frozen dairy desserts. The influence of stabilizers on the thermal prop...
Kinetic Parameters of Glass Transition in Glassy Se1 - xSbx Alloys
Differential scanning calorimetry Glass transition temperature Activation energy of glass transition
2010/4/12
Differential Scanning Calorimetry (DSC) is performed at different heating rates under non-isothermal conditions to study the glass transition kinetics of glassy Se1 - xSbx (x = 0.02, 0.04, 0.06, 0.08 ...
