Sentences with phrase «glass transition temperatures»
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.»
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.
Another quality of spider silk is its «glass transition temperature.»
Increased hydrodynamic radius (in solution) and glass transition temperature (in bulk materials) were observed upon metallation with Zn2 +.
The glass transition temperature of PLA is 60 — 65oC.
The new polymer must fuse with the previous layer and there are two keys to this — the temperature of polymer being extruded and keeping the model as close to the glass transition temperature as possible.
It is amorphous with no specific melting point but the temperature when it changes to a liquid state (glass transition temperature) is 105 degree celsius.
Stratasys were the first to market with an FDM machine and patented a heated chamber kept a few degrees below the glass transition temperature of the polymer.

Not exact matches
Transmission Electron Microscope (TEM) images of Pd - Ni - P metallic glass at different temperatures show the phase transition that involves structural changes in atomic clusters.
The combined measurements revealed that Pd - Ni - P metallic glass has a hidden amorphous phase within a certain temperature range and the thermodynamic inconsistency is the consequence of a phase transition.

The glass transition, or the temperature when cooled liquids transform into a glass, is another mystery.
Dr Royall said: «In doing so, they found that the dynamical interpretation of the glass transition seems to end at a «critical point», which is close to, or even coincides with, the temperature at which the ideal glass is formed.
There is a study of a German transition from traditional glass mercury thermometer measurement stations to the new electronic measurement system, http://notrickszone.com/2015/01/14/germanys-warming-happens-to-coincide-with-late-20th-century-implementation-of-digital-measurement/, where a side - by - side run of the old and new equipment for 8.5 years found that the new equipment yielded a temperature reading 0.93 C higher on average.
