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.

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.

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.

Researchers hoped graphene would prove an ideal material for terahertz-range lasers, but those hopes were dashed in the early 2010s. Now, researchers from the Moscow Institute of Physics and Technology propose Weyl semimetals, a 3D analogue of graphene, could be the answer.
