  1. Cheaper, Less Toxic And Recyclable Light Absorbers For Hydrogen Production
    4/10/2018

    Mimicking photosynthesis in plants, using light to convert stable and abundant molecules like water and CO2 into a high energy fuel (hydrogen) or into chemicals of industrial interest, is a major research challenge today.

  2. Mini Toolkit For Measurements: New NIST Chip Hints At Quantum Sensors Of The Future
    4/10/2018

    Researchers at the National Institute of Standards and Technology (NIST) have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities such as length with quantum precision. The design could be mass-produced with existing technology.

  3. Researchers Discover How Colliding Oxygen Molecules Absorb Light
    4/9/2018

    Scientists at Radboud University have managed to do what had never been tried before: accurately describe how colliding oxygen molecules absorb light. Our atmosphere consists of approximately 20 percent oxygen molecules, which constantly collide with each other and with the 80 percent of nitrogen molecules, and in doing so absorb light.

  4. Mimicking The Structural Color Of Insects, With Optical Applications
    4/9/2018

    The bright colors of some butterflies, beetles or birds are not due to the presence of pigments that selectively absorb light, but due to the so-called structural coloration.

  5. Sending Electrons On A Rollercoaster Ride
    4/9/2018

    A first-of-its-kind x-ray instrument for frontier research with high-brightness x-rays is now in operation at Argonne National Laboratory. The new device utilizes a unique superconducting technology that speeds electrons on a path much like that of a rollercoaster.

  6. Don’t Miss PPM Systems At the Three Counties Defence And Security Expo
    4/6/2018

    3 Counties Defence and Security Expo (3CDSE) 2017PPM Systems will be exhibiting highly advanced military-grade products, such as the Rodent 4 remote antenna platform, at the Three Counties Defence & Security Expo (3CDSE) this May.

  7. Series 9 Offers Wide Range Of APDs Optimized For LIDAR Applications
    4/6/2018

    With the Series 9, First Sensor offers a wide range of silicon avalanche photodiodes (APDs) with very high sensitivity in the near infrared (NIR) wavelength range, especially at 905 nm. With their internal gain mechanism, large dynamic range and fast rise time the APDs are ideal for LIDAR systems for optical distance measurement and object recognition according to the time of flight method. Application examples include driver assistance systems, drones, safety laser scanners, 3D-mapping and robotics. 

  8. SPIE Appoints Kent Rochford As New CEO
    4/6/2018

    SPIE, the international society for optics and photonics, announced recently that Kent Rochford will be the organization's new CEO.

  9. Twisting Laser Light To Probe The Nanoscale
    4/5/2018

    A new method to sensitively measure the structure of molecules has been demonstrated by twisting laser light and aiming it at miniscule gold gratings to separate out wavelengths.

  10. Gold Changes The Photoluminescence Of Silicon Quantum Dots
    4/5/2018

    Silicon quantum dots have a wealth of potential applications in cell biology and medicine thanks to their selective cell penetration capability and luminescence. Biosensors based on silicon quantum dots can be used as an early diagnosis tool for various diseases, while silicon nanocrystals hold great potential for developing silicon-based light-emitting devices and producing highly efficient solar cells.
