Nanopillars that Trap More Light The new design could lead to cheaper solar cells. Building the World's Most Powerful Laser New lasers will be key to making fusion energy and proton therapy practical. Nobel for Revolutionary Optical Technologies The Nobel Prize in physics was awarded to a fiber-optics pioneer and the inventors of digital-imaging chips. Nanoparticle inks that fade away in hours could be ideal for secure communications. Flexible arrays of bright inorganic LEDs could mean cheaper displays and lighting. Dye-doped DNA nanofibers can be tuned to emit different colors of light. OLEDs could soon give fluorescent lighting a run for its money. New E-Paper Technology Speeds Up Research shows that photonic crystals can change color as quickly as other technologies. Nanocrystals could light the way to using LEDs to replace the lightbulb. Easier Detection of Explosives A new substance could be used in portable sensors to reveal traces of explosives. Ultrasmall light-emitting fibers deposited on electrodes can serve as nanometer-scale light sources. Organic crystals change shape and then go back to their original shape when exposed to light of different colors. How to Make an Object Invisible A new theoretical design using nanowires provides a way to hide devices from visible light. Materials That Reflect No Light Solar cells, camera lenses, and LEDs could benefit from new antireflection coatings. [1]
