How new phase-change materials could lead to more efficient and faster data storage technologies

18-Jun-2019

Phase-change materials are used in the latest generation of smartphones enabling higher storage densities and energy efficiency. Data is recorded by switching between glassy and crystalline material states by applying a heat pulse. However, to date it has not been possible to study what happens ...

Using electricity rather than heat can reduce both energy costs and greenhouse gas emissions.

26-Aug-2016

The MIT researchers were trying to develop a new battery, but it didn’t work out that way. Instead, thanks to an unexpected finding in their lab tests, what they discovered was a whole new way of producing the metal antimony — and potentially a new way of smelting other metals, as well. The ...
