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 ...

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 ...

Glasses with transitional lenses are a neat idea in theory, but they have some shortcomings in practice. That's why researchers from the Georgia Institute of Technology are developing an alternative – ...

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 ...

Blessed are those with perfect vision, but the rest of us poor, nearly blind souls know the torture that is looking for sunglasses when we already have to wear glasses. The options are Fitovers that ...

The complex heat capacity for the glass transition region of the NR/SBR blend is shown in Figure 1. Figure 1. ADSC of an NR/SBR blend In the traditional DSC measurement curve, enthalpy relaxation is ...

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 ...
