Despite its ubiquity, the influence of grain shrinkage on cracking remains largely unexplored. Researchers from Princeton University investigated the phenomenon, and the results of their studies are described in two papers published this year.

Atomic structure plays an important role in understanding element properties. As the International Year of the Periodic Table nears its end, a new study looks at the potential superhydrides, specifically CeH9, hold as high-temperature superconductors.

In 2009, a theoretical simulation predicted wurtzite boron nitride had an indentation strength higher than diamond. Now, researchers in China and Saudi Arabia experimentally measured wBN’s hardness—and found it much closer to cubic boron nitride instead.

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.

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.

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.

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.

Previously, two separate theories described heat transport in ordered and disordered materials. A new general theory by Swiss and Italian researchers describes thermal transport in both, as well as everything in between.
