Professor Emeritus Donald Sadoway, renowned electrochemist and influential educator, reflects on 45 years at MIT.

A technique that transforms the metals’ microscopic structure may enable energy-efficient 3D printing of blades for gas turbines or jet engines.

J-WAFS Fellows discuss their inspiration for pursuing challenges in water and food systems.

With new techniques in electron microscopy, James LeBeau explores the nanoscale landscape within materials to understand their properties.

Metal stents or staples that disintegrate on demand inside the body could eliminate some surgical and endoscopic procedures.

Pacemakers and other medical devices, as well as long-distance drones and remote sensors, could require fewer battery replacements with new approach.

The device provides greater sensitivity and speed than previous versions, and could be used for industrial inspection, airport security, and communications.

By analyzing enzyme activity at the organism, tissue, and cellular scales, new sensors could provide new tools to clinicians and cancer researchers.
