Formation of Glasses from Liquids and Biopolymers
The onset of a sharp change in ddT( is the Debye-Waller factor and T is temperature) in proteins, which is controversially indentified with the glass transition in liquids, is shown to be general for glass formers and observable in computer simulations of strong and fragile ionic liquids, where it proves to be close to the experimental glass transition temperature.

C. Angell was born in Canberra, Australia, and studied chemistry and metallurgy at the University of Melbourne, and is focusing on the annealing behavior of hyperquenched liquids and solutions, particularly denatured protein solutions, with a sideline on nanoporous network glasses as gas storage media.
The Glass Transition: Relaxation Dynamics in Liquids and Disordered Materials
Imagine that you get such certain awesome experience and knowledge by only reading a book. How can? It seems to be greater when a book can be the best thing to discover. Books now will appear in
Relaxation in glassforming liquids and amorphous solids
The field of viscous liquid and glassy solid dynamics is reviewed by a process of posing the key questions that need to be answered, and then providing the best answers available to the authors and
Liquids at Large Negative Pressures: Water at the Homogeneous Nucleation Limit
An isochoric cooling method for obtaining unprecedented tensions on liquids was used to determine the homogeneous nucleation limit for stretching of water at a variety of water densities, and confirms the existence of a density maximum at 42�C and –140 megapascals and greatly strengthens the basis for Speedy's conjecture of a reentrant spinodal for water.

Nonexponential relaxations in strong and fragile glass formers
Deviations from thermally activated and from exponential response are typical features of the vitrification phenomenon and previously have been studied using viscoelastic, dielectric, calorimetric,
Isothermal compressibility of supercooled water and evidence for a thermodynamic singularity at −45°C
Using a capillary technique for small samples, the isothermal compressibility κ T of water has been measured to −26°C. Accelerating increases of κ T at the lower temperatures can be described by an
Thermodynamic determination of fragility in liquids and a fragile-to-strong liquid transition in water
If crystallization can be avoided when a liquid is cooled, it will typically form a glass. Near the glass transition temperature the viscosity increases continuously but rapidly with cooling. As the
