(Phys.org) -- When chemists look at a drinking glass filled with water and a few ice cubes, it's not clear to them whether the glass is more like the water or the ice. Glass is one of civilization's ...

A collaborative group from Tohoku University and Johns Hopkins University have provided valuable insights into the glass transition. When a liquid is cooled rapidly, it gains viscosity and eventually ...

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 ...

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 ...

While the familiar melting and freezing transitions of water occur at well-defined temperatures, the transitions in polymers are surprisingly different At this time of year it always becomes obvious ...

This series of articles is designed to help molders understand how a few analytical tools can help diagnose a part failure. Michael Sepe is our analyst and author. He is the technical director at ...

Changes in temperature can have an enormous impact on the performance properties of epoxies and other thermosetting polymer systems. Prior to curing, an epoxy consists of a resin and a curing agent.

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 ...
