A tale of two SiC slurries—and how open science may someday impact research

By Jonathon Foreman / February 25, 2020

Fabricating dense, complex-shaped items from silicon carbide can be challenging due to the material’s properties. Manufacturers benefit from studies on reducing viscosity of SiC slurries, such as two recent ones published in an ACerS journal, but open access to the data behind such studies may benefit them even more.

Cracking the case toward commercial solar—perovskite films easily healed with moderate compression or heat

By Lisa McDonald / February 18, 2020

Perovskite solar cells are expected to become a leading contender to silicon-based solar cells, or for use in tandem with them, once several challenges are overcome. Researchers at Brown University found cracks in perovskite films are easily healed by applying compression or moderate heat.

Doing double duty in the circular economy—creating foam glass from waste materials

By Jonathon Foreman / January 28, 2020

Porous ceramics hold great promise as value-added products for waste materials because they can use ceramic and glass powders as starting materials. Two recent papers published in a special issue of ACT explore this idea by creating foam glass from waste.

Guided self-assembly: Templating gives control over eutectic material structure

By Lisa McDonald / January 24, 2020

Eutectic materials self-assemble to form a cohesive structure, but only a limited set of structures emerge. Researchers from the University of Illinois at Urbana-Champaign and the University of Michigan found they could achieve new microstructures through templating.

Reduce carbon emissions from cement production—and make other useful products in the process

By Lisa McDonald / November 5, 2019

To reduce carbon emissions from cement manufacturing, emission-heavy steps of the process can be replaced with alternative techniques. Researchers from the Massachusetts Institute of Technology experimented with using electrolysis to create cement and found that in addition to reducing carbon emissions, byproducts from the process can be reused.

Nanoparticles and flash sintering—increasing ductility of glass and ceramics

By Lisa McDonald / October 15, 2019

Both glass and ceramics can be quite brittle. Two recent studies look at increasing the ductility of each—one through the consolidation of glassy nanoparticles, and the other through flash sintering.
