New holographic data storage medium could enable wearable technology that captures and stores detailed 3D images. New nanoparticle-based films that are more than 80 times thinner than a human hair may provide materials that can holographically archive more than 1,000 times more data than a DVD in a 10-by-10-centimeter piece of film...

Princeton engineers have refined the manufacturing of light sources made with crystalline substances, perovskites, a moreefficient and potentially lower-cost alternative to materials used in LEDs found on store shelves. The researchers developed a technique in which nanoscale perovskite particles self-assemble to produce more efficient, stable and durable perovskite-based LEDs. The advance, reported January 16 in Nature Photonics, could speed the use of perovskite technologies in commercial applications such as lighting, lasers and television and computer screens.
LEDs emit light when voltage is applied across the LED...
