Toward next-gen thermochromic glass: Researchers improve understanding of insulator-metal transition in vanadium dioxide films

By Lisa McDonald / September 18, 2020

Vanadium dioxide is being actively investigated for use in thermochromic glass due to its insulator-metal transition. However, the mechanism behind this transition is still not well understood. Researchers in Russia used the framework of blow-up overheating instability to improve understanding of this transition.

A hu‘gel’y promising method: Support bath simplifies additive manufacturing of polymer-derived ceramics

By Lisa McDonald / September 15, 2020

Polymer-derived ceramic structures are difficult to manufacture using additive manufacturing processes because of low viscosity of the polymer state. Researchers at the University of Texas at Dallas successfully demonstrated the use of gel-like viscoplastic fluid to support preceramic polymers during the printing process.

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.
