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 ...

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 ...

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 ...

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 ...

Thermoplastics are processed in the molten state, their final shape and internal structure are established by cooling, and they can be softened and reshaped by reapplication of heat and pressure. Also ...

The modern world is filled with synthetic polymers, long-chained molecules designed by scientists to fill all manner of applications. Researchers at FAMU-FSU College of Engineering have developed two ...

The increasing commercialization of space has found the industry under the environmental microscope, as its few conservation regulations could have ominous consequences if left unaddressed. Photo ...

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 ...
