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 ...

THE variation of ultrasonic velocities with temperature in methyl methacrylate polymers was determined by Protzman 1 and by Melchor and Petrauskas 2. Using the optical diffraction method, Protzman ...

Polymer matrix composites (PMCs) exhibit impressive stiffness and strength properties that are commonly attributed to the reinforcing fibers. However, for many important mechanical properties, the ...

Glass transition temperature (T g) is usually measured in relation to material stiffness, or modulus, and may also be known as the principal relaxation. The glass transition temperature of a thermoset ...

As anyone who extrudes plastic noodles knows, the glass transition temperature of a material is a bit misleading; polymers gradually transition between a glass and a liquid across a range of ...

Ultramicrotome Sectioning enables precise preparation of polymer samples using room temperature and cryo techniques for ...

High-Q microcavities have provided increasing opportunities for optical sensing and precision measurement in the past decades, with intriguing features of miniature size, non-invasiveness and fast ...

A new high-temperature polymer fuel cell that operates at 80-160 degrees Celsius, with a higher-rated power density than state-of-the-art fuel cells, solves the longstanding problem of overheating, ...
