Light Beam Observation Extends Beyond Spectrum of Disorder
ROSTOCK, Germany, June 14, 2022 — Researchers from the University of Rostock and the Technion, Israel Institute of Technology demonstrated a mechanism that prevented lightwaves from spreading freely. The underlying physical effect was previously considered too weak to fully arrest wave expansion. The researchers observed that such light localization was nevertheless possible, demonstrating the sensitivity of wave propagation across a wide range of spatial length scales. In 1958, physicist Phil Anderson predicted that an
Reusable Light-Writing Solution Reduces Paper Waste
RIVERSIDE, Calif., June 14, 2022 — A team led by professor Yadong Yin at the University of California, Riverside formulated a light-sensitive coating material for rewritable light-printing. The material is made from doped titanium dioxide (TiO2) nanocrystals that are synthesized in a...
