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.

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.
