Energy Efficiency

A new MIT platform enables researchers to “grow” halide perovskite nanocrystals with precise control over the location and size of each individual crystal, integrating them into nanoscale light-emitting diodes.

Researchers Grow Precise Arrays of nanoLEDs, Perovskite Nanocrystals

A new technique produces perovskite nanocrystals right where they’re needed, so the exceedingly delicate materials can be integrated into nanoscale devices.

University of Illinois Urbana-Champaign engineers have developed a new breed of display screens that use flexible fins, varying temperatures and liquid droplets that can be arranged in various orientations to create images. The control is precise enough to achieve complex motions, like simulating the opening of a flower bloom. Image courtesy Sameh Tawfick

Displays Controlled By Flexible Fins & Liquid Droplets More Versatile & Efficient Than LED Screens

Engineers inspired by the morphing skins of animals like chameleons and octopuses
