A multi-scale heterostructure design—combining micrometre-scale grains with nanoscale precipitate networks—enables a ...

Knots are known for boosting the strength of materials, from the tiniest twists of DNA to (potentially) the very fabric of the universe. Now, Caltech engineers have developed a new material consisting ...

A new material may be the key to quickly flag damaged infrastructure. This material offers a way to reduce the manpower required to regularly monitor structures that undergo daily use such as bridges.

What is Hall-Petch Strengthening? Hall-Petch strengthening is a phenomenon where decreasing the average grain size of a material leads to increased yield strength and hardness. This effect is ...
