  • Professor Yingtian Pan, right, and his student Jiang You, left, and lab associate Ki Park, developed a quantitative imaging technique that shows how cocaine disrupts brain blood flow

    What’s New for OCT?

    Optical coherence tomography (OCT), which has been used for non-invasive ophthalmology imaging for some time, is now starting to find greater clinical use in other medical applications such as cardiology. For example, physicians are using OCT to...
  • The flexible sensor could be integrated into low-cost sensing systems for in-line diagnostics and monitoring

    Multispectral Light Sensors Built from Doped Nanorods

    Semiconductor-based photodiodes are widely used in industry to detect light at a range of frequencies from the ultraviolet through the visible to the near infra red. Such photodiodes operate by absorbing photons, which then generate a flow of...
  • Professor Zenghu Chang from the Department of Physics and the College of Optics and Photonics at the University of Central Florida set a world record when he produced an attosecond pulse just 67as in duration

    Lasers Freeze Electron Movement

    Massachusetts Institute of Technology (MIT) professor Harold Edgerton is widely known as a pioneer in the field of ultra-high speed photography. By synchronizing strobe flashes with the motion of objects, then taking a series of photographs through...
  • IMEC researchers have found that illumination stabilizes the morphology of polymerfullerene bulk heterojunction BHJ solar cells that are exposed to elevated temperatures

    Light-Induced Stabilisation of Organic Solar Cells

    Organic solar is a topic of much interest because of their light weight, flexibility and low manufacturing costs. At IMOMEC, Imec’s associated lab at Hasselt University in Belgium, researchers have found that illumination stabilizes the...
  • Fraunhofer researchers have developed a technique to produce mini-OLED screens without colour filters

    OLED Production Technique Slashes Costs, Improves Luminosity

    Screens made of organic light-emitting diodes (OLEDs) are a promising technology. Until now, however, a minimal lifespan and very high production costs have prevented them from becoming a widespread commercial product. Researchers at the Fraunhofer...
  • WUSTLs receive-only 2D camera can capture events up to 100 billion frames per second

    World’s Fastest 2D Camera Captures Light Pulses on the Fly

    Biological engineers at Washington University in St. Louis (WUSTL), Missouri (US), have developed the world’s fastest receive-only 2D camera. The device can capture events up to 100 billion frames per second, orders of magnitude faster than...
  • View through the channels of Si24 This new zeolite-type allotrope of silicon isotypic with the zeolite CAS has an open framework comprised of 5-, 6- and 8-membered sp3-bonded silicon rings Credit Timothy Strobel

    Silicon Allotrope With Quasi-Direct Band Gap

    In a fundamental discovery, scientists at the Carnegie Institution for Science in Washington, District of Columbia (US), have synthesised an entirely new, solar-friendly form of silicon that could revolutionise solar technologies and other...
  • UC San Diegos nanoparticle-based material

    Nanoparticle-Based Material Converts 90% Sunlight Into Heat

    Engineers at the University of California, San Diego (UC San Diego) have developed a nanoparticle-based material for concentrating solar power plants that converts more than 90% of captured sunlight into heat. With intentionally varying particle...

    Super-Efficient Hybrid Solar Cells Thanks to Triplet Excitons

    Researchers from the University of Cambridge (UK) have demonstrated for the first time that it is possible to transfer energy from organic to inorganic semiconductors via so-called triplet excitons. Being able to extract the electrons from these...
  • Dr Simon Lefrancois from the University of Sydneys School of Physics holding an optical chip used in the terabit oscilloscope

    Super Optical Oscilloscope With Chalcogenide Glass Chips

    In what could be a major advance in developing a diagnostic tool for next-generation ultrafast fibre optics communications systems used for broadband internet and cloud computing, researchers at the Centre for Ultrahigh bandwidth Devices for...
  • Sandia National Laboratories researcher Vitalie Stavila inserts a substrate patterned with electrodes into a temperature-controlled liquid-phase reactor for depositing MOF thin films
  • ELED lighting could reduce energy consumption in greenhouse horticulture sector by 50

    LED Lighting Saves Energy in Greenhouse Horticulture

    The Dutch are global leaders in greenhouse horticulture, so it makes sense that Leo Marcelis, professor in horticulture and product physiology at Wageningen University in The Netherlands is advocating the introduction of LED lighting in an effort...
