  1. ‘Quantum Dot’ Lighting Technology Takes Forward Leap Thanks To New Superacid Treatment

    A “superacid” much stronger than automobile battery acid has enabled a key advance toward a new generation of LED lighting that’s safer, less expensive and more user friendly.

  2. Flat Gallium Joins Roster Of New 2-D Materials

    Scientists at Rice University and the Indian Institute of Science, Bangalore, have discovered a method to make atomically flat gallium that shows promise for nanoscale electronics.

  3. Scaling Silicon Quantum Photonic Technology

    An international team of quantum scientists and engineers led by the University of Bristol and involving groups from China, Denmark, Spain, Germany and Poland, have realised an advanced large-scale silicon quantum photonic device that can entangle photons to incredible levels of precision.

  4. High-Power Laser Throws Light On Radiation Reaction

    Electromagnetic radiation is all around us. It’s in the radio waves that make mobile phones work, in the rainbow we see when it rains on a sunny day, and in the invisible infrared waves we use in our remote controls to change TV channels.

  5. Russian Physicists Make Toy Asteroids And Blast Them With A Laser

    A large team of Russian researchers from Rosatom, joined by three MIPT physicists, has modeled the impact of a nuclear explosion on an Earth-threatening asteroid. They manufactured miniature asteroids and blasted them with a laser.

  6. New Ultrafast Measurement Technique Shows How Lasers Start From Chaos

    How do laser pulses emerge? A recent research paper co-authored by photonics researchers from TUT and published in Nature Photonics demonstrates how laser pulses emerge from noise as if out of nowhere and display complex collapse and oscillation dynamics before settling down to stable operation.

  7. Movable Silicon ‘Lenses’ Enable Neutrons To See New Range Of Details Inside Objects

    You can’t see well without lenses that can focus, whether those lenses are in your eye or the microscope you peer through. An innovative new way to focus beams of neutrons might allow scientists to probe the interiors of opaque objects at a size range they were blind to previously, allowing them to explore the innards of objects from meteorites to cutting-edge manufactured materials without damaging them.

  8. Self-Driving Cars Could Use Lasers To See Around Blind Corners

    Stanford University researchers have developed a laser-based system that can reproduce images of objects hidden from view. The technology can be used to enhance the safety of self-driving vehicles, as well as applied to serve other functions.

  9. MIPT Physicists Tune A Spin Diode

    A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes, it is possible to change the resistance and the resonant frequency of the diode.

  10. Opto Diode Introduces Deep Red Surface-Mount LED

    Opto Diode Corporation, an ITW company, introduces a deep red, surface-mount device (SMD) light-emitting diode (LED) that delivers exceptional efficiency for biological analysis, health, science, medical, and veterinary applications. OD-685C LED features 2.0mW of radiant power at a forward current of 20mA, peak wavelength of 685nm, and radiant efficiency of 56 percent. Typical applications require radiometric measurement with tight spectral bandwidth.
