New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

New Mechanism of Photoconduction Could Lead to Next Generation Excitonic Devices

Physicists at MIT have discovered that shining light on a single layer of molybdenum disulfide (MoS2) can make the material less conductive. It’s a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered that […]

Crumpled Graphene Forms Stretchable Supercapacitors

New research from engineers at MIT details how two-dimensional carbon “paper” can form stretchable supercapacitors to power flexible electronic devices. When someone crumples a sheet of paper, that usually means it’s about to be thrown away. But researchers have now found that crumpling a piece of graphene “paper” — a material formed by bonding together […]
