Most bioglasses, especially the popular 45S5, form weak scaffolds prone to cracking because they do not sinter to full density. Researchers looked to understand the factors hindering densification.

In May, a formula was published that could describe thermal transport in both crystals and glass. Now, a new formula by researchers in Italy and the United States based on a different mathematical framework can also model such thermal transport.

Phase change materials are an excellent way to store data—if you know how to effectively switch between the material’s glassy and crystal states. Researchers at the University of Arizona and RWTH Aachen University discovered unlike most glasses, the PCM Ge2Sb2Te5 can switch directly from glassy to crystal without entering the liquid phase.

Reducing oxide glass brittleness is an active area of research. Researchers at the University of California, Los Angeles, created a tough oxide glass with a stress-modulus relationship near the theoretical limit by dispersing nanoparticles in a glass melt.

A main shortcoming of oxide glasses is that they are brittle. Researchers in Denmark and the United States found they could increase the crack resistance of such glasses enormously by subjecting the glass surface to humid aging.

Knowing the type of glass in your car side windows could save you in an emergency. A new study by AAA found that out of six vehicle escape tools, only four could shatter tempered glass and none could break laminated glass, which stayed intact even after being cracked.
