Sentences with phrase «glass transition temperature»

At the so - called glass transition temperature, the relaxation time is on the order of a few minutes.

Loosely bound water (mostly from urine) is separated using low glass transition temperature hollow - fibre membranes.

Additionally, we recently have reported ion - conducting copolymer systems in which judicious choice of taper geometry led to reductions in block glass transition temperatures, which ultimately reduced barriers to ion - transport and enhanced conductivity.

There is a principle in polymer chemistry called the «time - temperature superposition,» which says that fibres with low glass transition temperatures will also cope well with sudden dynamic loads — such as those that a parachute rope is subject to.»

These motions are constrained by localised forces in the molecular environment and, in contrast to the relatively large motions that happen above the glass transition temperature, the molecular motions above the lower temperature threshold are much subtler.

Using a technique called dynamic mechanical analysis as well as terahertz spectroscopy, Zeitler and his colleagues showed that instead of the glass transition temperature, the molecular motions occurring until a lower temperature threshold, are responsible for crystallisation.

In order to determine when and how solids will crystallise, most researchers had focused on the glass transition temperature, which is the temperature above which molecules can move in the solid more freely and can be measured easily.

The temperature that an amorphous solid is changed from a glassy, rigid state to a viscous, rubbery state is known as the glass transition temperature.

Although tea powders degrade slower below the glass transition temperature, they can still degrade.
