Viscosity and Glass Transition in Amorphous Oxides [PDF]
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 accompanied by explicit discontinuities in the derivative ...

Glass transition temperatures of pure glass-forming liquids and binary mixtures [PDF]
The glass transition remains one of the most enduring and debated problems in condensed matter science, engaging researchers across disciplines. Two main approaches have traditionally been used to study the glass transition in pure glass formers and ...

Perspective: The glass transition [PDF]
We provide here a brief perspective on the glass transition field. It is an assessment, written from the point of view of theory, of where the field is and where it seems to be heading. We first give an overview of the main phenomenological characteristics, or “stylised facts,” of the glass transition problem, i.e., the central observations that a ...

To investigate the effects of steaming treatment on crystallinity and glass transition temperature, samples of Eucalyptuses grandis × E. urophylla with moisture content of 50%, 70%, and 90% were steamed in saturated steam at 100 °C for 2, 4, 6, and 8 h ...

Configurons: Thermodynamic Parameters and Symmetry Changes at Glass Transition
Thermodynamic parameters of configurons – elementary excitations resulting from broken bonds in amorphous materials – are found from viscosity-temperature relationships.

Glass transition temperatures of binary oxides from ab initio simulations
The glass transition temperatures of common binary oxides, including those with low glass-forming ability, are estimated using pair distribution functions (PDFs) from ab initio molecular dynamics simulations.

The glass transition in molecules, colloids and grains: universality and specificity
We highlight certain key achievements in experimental work on molecular, colloidal and granular glassformers. This short review considers these three classes of experimental systems and focusses largely on the work of the authors and their coworkers and ...

The glass transition temperature investigation of polymers by molecular dynamic simulations
In this paper, the process of glass transition is studied, the theory of which is not fully developed. Computer modeling can be used to understand the theory of this phenomenon. The glass transition temperature is influenced by a large number of polymer

Orientational glass transition [PDF]
The static behavior of orientational glasses is discussed in terms of a replica theory based on the infinite range random bond--random field model. A general version of the model applicable to dipolar and quadrupolar glasses is presented using a symmetry-adapted representation for the order parameter fields.

Correlation between fragility and free volume void size at glass transition temperature
Despite the tremendous endeavors devoted to exploiting the nature of glass transition, the factors that control the steepness index of viscosity near glass transition, that is, fragility, remain unclear.
