MINNEAPOLIS, Feb. 22, 2017 — Windows that can efficiently collect solar energy are one step closer to becoming a reality thanks to high-tech silicon nanoparticles. Researchers at the University of Minnesota and University of Milano-Bicocca have developed technology to embed the...
3D Computer Vision Helps Autonomous Vehicles Locate Themselves on Maps
BROOKLYN, N.Y., Feb. 22, 2017 — Self-driving cars need onboard artificial intelligence (AI) technology able to link them to highly detailed maps that reflect every change in the status of lanes, hazards, obstacles, and speed-limits in real time. Researchers at the NYU Tandon...
Photon Gun Could Further Development of Photonic Quantum Network
COPENHAGEN, Denmark, Feb. 21, 2017 — A photonic nanostructure for constructing quantum photonic circuits for quantum networks has been developed, which could impact the optics and photonics that underlie quantum information processing. Photons (unlike electrons) display weak...
Alfaro Wins Best Paper Award
HEIDELBERG, N.Y., Feb. 20, 2017 — Purdue University Ph.D. candidate Clint Alfaro has received the 2016 Analytical and Bioanalytical Chemistry Best Paper Award from Springer International Publishing AG, publisher of the Analytical and Bioanalytical Chemistry (ABC). In a paper...
Optical Diffusers Improve Definition, Viewing Angle for 3D Holograms
DAEJEON, South Korea, Feb. 17, 2017 — A wavefront shaping technique has been used to create a dynamic 3D holographic image with a viewing angle of 35 degrees in a volume of 2 cm in length, width and height. Use of the technique was shown to yield a 3D holographic display that performed...
New Bilayer Material Could Improve LED Technology
LAWRENCE, Kansas, Feb. 17, 2017 — A new bilayer material measuring less than one nanometer in thickness per layer could lead to more efficient and versatile light emission. Researchers working at the Ultrafast Laser Lab at the University of Kansas (KU) successfully created the...
Lidar Yields Clues into Native American History
Feb 17, 2017 — Archaeologists have been using lidar to advance investigations of the past, primarily in areas where there were known large-scale civilizations in dense forested settings, such as Mayan areas in Central America and Angkor Wat in Cambodia. For...
