Polystyrene has a glass transition temperature of about 100 C -- at room temperature it behaves like a solid material. But as its temperature approaches the glass transition temperature, polystyrene’s ...

The melting of crystals is the process by which an increase in temperature induces the disruption of the ordered crystalline lattice, leading to the disordered structure and highly fluctuating dynamic ...

Changes in a liquid as it becomes a glass are related to repulsion between atoms as they are crowded together. Although scientists have long believed the poorly understood glass transition must have ...

The glass transition represents a remarkable transformation whereby a supercooled liquid becomes an amorphous, non-crystalline solid. Unlike standard phase transitions, this process involves a ...

The process of liquid-to-glass transition is a complex procedure in science, as is the glass-to-liquid transition known as glass melting. In a new report published in Science Advances, Qi Zhang and a ...

The determination of glass transition temperature (Tg) is critical for understanding a material's properties. It indicates the temperature at which a substance transforms from a glassy state to a ...

The National Science Foundation has awarded $1.65 million to a project led by Washington University in St. Louis physicist Ken Kelton to build an electrostatic levitation chamber that will be ...

WASHINGTON, D.C., March 21, 2017 -- Polymers are used for myriad applications today, and perhaps the most important property that dictates which polymer is chosen for a given application is its "glass ...
