Persistence is key—topological data analysis reveals hidden medium-range order in glass

By Lisa McDonald / September 11, 2020

Understanding the atomic structure of glass and other amorphous materials is difficult because, unlike crystals, the structure only consists of short-range and medium-range order; long-range order is absent. Researchers led by Aalborg University demonstrate how a topological method called persistent homology could help reveal a glass’s medium-range order structural features.

Exploring the mechanical behavior of MOF glasses

By Lisa McDonald / May 26, 2020

Metal-organic frameworks have immense potential in various applications but are difficult to synthesize in bulk. Fabricating MOFs in the glassy phase provides the necessary stability for bulk synthesis, and two new studies investigate the mechanical properties of these unique glasses.

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.
