Scalable manufacturing process spools out strips of graphene for use in ultrathin membranes. MIT engineers have developed a continuous manufacturing process that produces long strips of high-quality graphene. The team’s results are the first demonstration […]

This scanning electron microscope image shows ultrafine diamond needles (cone shapes rising from bottom) being pushed on by a diamond tip (dark shape at top). These images reveal that the diamond needles can bend as much as 9 percent and still return to their original shape.

The brittle material can turn flexible when made into ultrafine needles, researchers find. Diamond is well-known as the strongest of all natural materials, and with that strength comes another tightly linked property: brittleness. But now, […]

Chief Editors Professor Valentin Popov and Dr. Roman Pohrt will foster multidisciplinary knowledge exchanges on tribology — a subject integral to any system with moving parts. Tribology — the study of friction and wear — […]

“We are particularly interested in wetsuits for surfing, where the athlete moves frequently between air and water environments,” says Anette (Peko) Hosoi, a professor of mechanical engineering and associate head of the department at MIT. “We can control the length, spacing, and arrangement of hairs, which allows us to design textures to match certain dive speeds and maximize the wetsuit's dry region.”

Beaver-inspired wetsuits in the works

Rubbery hair-lined wetsuits may help keep surfers warm. Beavers and sea otters lack the thick layer of blubber that insulates walruses and whales. And yet these small, semiaquatic mammals can keep warm and even dry […]

MIT researchers have developed a new platform for microfluidics, using LEGO bricks. Shown here, fluid flows through tiny channels milled into the side walls of LEGO bricks.
