‘Molecular glue’ enhances perovskite solar cell reliability

By Lisa McDonald / May 18, 2021

Perovskite solar cells struggle with long-term reliability due to their love–hate relationship with the sun. Brown University researchers explored using self-assembled monolayers to “glue” interfaces within the cells and thus make the cells more efficient, stable, and reliable.

Novel processing technique enhances toughness of high boron steel

By Lisa McDonald / May 7, 2021

Boron can enhance mechanical properties of steel, but too much boron will segregate from the steel and negate these benefits. Researchers led by Wuhan University of Science and Technology looked to enhance the toughness of high boron steel using a novel processing technique called quenching and partitioning.

Designing better ballistic materials: Reduced processing costs, higher toughness, and microstructural cues

By Jonathon Foreman / March 23, 2021

Designing better ballistic materials is more than a matter of finding the optimal combination of material properties—a deep understanding of the microstructure–damage relationships is required as well. A number of recent articles published in ACerS journals look to improve processing methods for fabricating dense, resilient ceramic components.
