Achieving full density—a look at factors hindering densification of bioglass scaffolds

By Jonathon Foreman / September 17, 2019

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.

Ultrathin glass goes ultrawide

By Jonathon Foreman / August 30, 2019

Glass panels with large dimensions can be fabricated using the float glass process—but can the process also fabricate ultrathin glass? Scientists at the State Key Laboratory for Float Glass in China report it can—while still retaining large dimensions.

Two theories, one goal—new formula also describes heat flow in both crystals and glass

By Lisa McDonald / August 30, 2019

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.

Directly from glassy to crystal: Phase change material switches state without entering liquid phase

By Lisa McDonald / August 27, 2019

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.

Nearing the theoretical limit of strength—nanoparticles toughen oxide glass

By Lisa McDonald / August 13, 2019

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.

From 30 N to 490 N—breaking the limit of oxide glass microductility

By Lisa McDonald / July 30, 2019

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.
