These images show the crystal configurations, or phases, within samples of metal alloys: a single-phase stable alloy (left) and a dual-phase alloy (right), which is metastable (has more than one stable configuration). The dual-phase material turns out to have better strength and ductility than the singe-phase material, the researchers found.

New metal alloys overcome strength-ductility tradeoff

Promising new approach overturns widespead metallurgical assumption.

MIT postdoc Cui-Zu Chang works with equipment that can monitor topological insulator thin-film quality as it grows. The bright green vertical bar on computer screen is an indicator of very high-quality film growth. Chang led work in the Moodera group showing the first zero-resistance edge state in a circuit.

MIT Senior Research Scientist Jagadeesh Moodera stands in front of a custom-built system used to fabricate ultrathin films. His work includes devices that exhibit resistance-free, spin-polarized electrical current; enabling memory storage at the level of single molecules; and the search for the elusive Majorana fermions sought for quantum computing.

Research highlight: Jagadeesh Moodera

Step-by-step, the Moodera Research Group is building the essential knowledge and hardware for next-generation quantum computers.

“When you look at coal as a material, and not just as something to burn, the chemistry is extremely rich,” says Jeffrey Grossman. In this photo, a sample of pulverized coal (right) is shown with several test devices made from coal by the MIT researchers.

Making electronics out of coal

Instead of burning up this complex hydrocarbon, let’s make devices from it, says Jeffrey Grossman.

An electron microscopy image shows many examples of nanoscrolls. The insert zooms in on a single nanoscroll and reveals its conical nature.

For stronger, lighter, cheaper materials, scroll up

Researchers create perfect nanoscrolls from graphene’s imperfect form.

Researchers have found a new kind of long-range interaction between particles, in a liquid medium, that is based entirely on their motion. Alfredo Alexander-Katz describes the kind of interactions his team found as being related to the research field of active matter. Example of active systems are the flocking behavior of birds or the schooling of fish. In this illustration, moving particles in a ...
