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 ...

Physicists simulate an ideal glass that’s crystal-hard but liquid-like
A team of physicists has computationally constructed a two-dimensional material that behaves like a paradox: it is disordered ...
For millennia, people have used molten sand and other ingredients to create glass and fashion beads, vessels, lenses and windows. These days, metallic glasses - made entirely of metal atoms - are ...
The complex heat capacity for the glass transition region of the NR/SBR blend is shown in Figure 1. Figure 1. ADSC of an NR/SBR blend In the traditional DSC measurement curve, enthalpy relaxation is ...
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 ...
Pair potentials of PMMA spheres. (A) Pair potential U(r) as function of center-to-center distance at 27°C extracted from radial distribution function g(r) (fig. S1 ...
The National Science Foundation has awarded $1.65 million to a project led by Washington University in St. Louis physicist Ken Kelton to build an electrostatic levitation chamber that will be ...
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 ...
