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.

Magnonics, an alternative to conventional electronics

By Lisa McDonald / September 3, 2019

Magnonics, an emerging field of magnetism, could provide an alternative method of data manipulation to silicon electronics. Researchers from universities in Russia, the Netherlands, and Germany developed a superconducting/ferromagnetic material for magnonic applications.

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.

Rust: Another way to generate electricity

By Lisa McDonald / August 6, 2019

Rust is commonly considered a problem to be suppressed. Researchers from the California Institute of Technology and Northwestern University instead show rust can be beneficial when used to generate electricity.

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.

Set sail on the road to discovery: Chemical map charts course to hundreds of new nitrides

By Lisa McDonald / June 28, 2019

Exploratory synthesis of nitride materials can be a time-consuming and risky venture. A new map of ternary metal nitrides gives scientists a good idea of where to look for new nitrides.

A perfect material for lasers is the 3D analogue of graphene

By Lisa McDonald / May 28, 2019

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.

Oxygen-11: The lightest-ever isotope of oxygen

By Lisa McDonald / May 17, 2019

Though discovering new elements beyond the 118 confirmed will be difficult, there are abundant opportunities for isotope discovery. The first new isotope confirmed in 2019 is oxygen-11, the lightest-ever form of oxygen to date.

Predicting macroscale friction in clay-like materials using microscale calculations

By Lisa McDonald / April 12, 2019

Japanese researchers found they could explain macroscopic friction in muscovite using theoretical calculations of microscale frictional forces. They hope to develop a theory that can explain frictional strength across a broad range of clay and clay-like minerals.
