Relict no more—purposeful inclusion of lime clasts gives Roman concretes self-healing properties

By Lisa McDonald / January 20, 2023

Traditionally, researchers have considered aggregate-scale lime clasts in Roman concretes to be relicts of the concrete fabrication process. Researchers led by Massachusetts Institute of Technology instead argue that these clasts were purposefully included to provide the concretes with self-healing properties.

Extensive modeling leads to new shape-memory zirconia with properties on par with shape-memory alloys

By Guest Contributor / December 20, 2022

Even when a shape-memory ceramic’s lattice compatibility is improved, it still often experiences cracking after just a few dozen transformation cycles. Researchers at the Massachusetts Institute of Technology improved the cyclability of shape-memory zirconia ceramics with the help of a multimode modeling approach.
