They may be tiny weapons, but a holography research group has figured out how to create lightsabers - green for Yoda and red for Darth Vader, naturally - with actual luminous beams rising from them.
Researchers have developed and characterized a new semiconductor material for application in process components stimulated by light. The findings have, for the first time, suggested a new way to reduce the band gap in cheaper and non-toxic tin-based oxide semiconductors for efficient light-based applications.
Researchers have shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.
Atomic-scale optical spectroscopy revealed huge Raman scattering when an atomic point contact is formed between a plasmonic silver tip and a single-crystal silicon surface. Atomic point contact Raman scattering paves the way for ultrasensitive atomic-scale vibrational spectroscopy to investigate surface structures.
Like conductors of a spooky symphony, researchers have 'entangled' two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks.
Researchers have numerically simulated and experimentally demonstrated a pixelated metasurface based on the silicon-on-insulated (SOI) wafer. According to the researchers, the metasurface can realize detection of full-Stokes polarization vectors in near infrared.
