Consequences of methodology—influence of indenter tip radius on failure mechanisms in borided steel

By Lisa McDonald / February 22, 2022

Replication studies have demonstrated how slight changes in methodology can significantly affect results. Researchers in Mexico investigated the effect that one seemingly minor methodological change can have on experiments—the radius of the indenter tip used in scratch testing.

Standard sintering aids and dispersants can degrade lasing performance of transparent ceramics

By Lisa McDonald / February 11, 2022

The use of transparent ceramics as a gain medium in lasers is an evolving field, and there is still much to learn about how processing parameters affect the ceramics’ performance. Researchers in Singapore and China published two papers investigating the possible effects of a standard sintering aid and dispersant on lasing performance.

Melting the unmeltable—new method extends the range of meltable MOF materials

By Lisa McDonald / October 12, 2021

Fabricating metal-organic frameworks in a glassy phase is a successful way to synthesize these materials for bulk production. However, some MOFs decompose before reaching the melting temperature and so cannot be turned into a glass. Researchers in Germany and the U.K. found a way to melt these unmeltable MOFs by adding ionic liquid to the compound.

To bilayers and beyond—researchers overcome the single-atomic-layer limit of borophene

By Lisa McDonald / August 31, 2021

Synthesizing multilayer borophene is difficult because of the tendency of boron atoms to cluster. Researchers at Northwestern and Rice Universities discovered they could synthesize bilayer borophene by growing it on a special silver substrate.
