  1. Multifunctional Metalens Unlocks With Light

    Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a flat optical component that is simultaneously a metalens, a microscope objective that can resolve details smaller than a wavelength of light, and an optical vortex and hologram generator. Each functionality is controlled by a different wavelength of light.

  2. Graphene Flakes For Future Transistors

    Tiny and very promising for possible applications in the field of nanoelectronics: they are the graphene nanoflakes studied by a SISSA’s team and protagonists of a study recently published in the Nano Letters journal.

  3. Quantum Mechanics Runs Hot In A Cold Plasma: UBC Research

    University of British Columbia researchers have found a new system that could help yield ‘warmer’ quantum technologies.

  4. 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.

  5. Bristol Instruments Introduces New WDM Wavelength Meter

    Bristol Instruments, Inc., a leader in optical interferometer-based instrumentation, announces the introduction of the new 828A Optical Wavelength Meter. This latest model utilizes a unique Fizeau etalon design to measure the absolute wavelength of CW and modulated optical signals to an accuracy as high as ± 0.3 pm, while also providing the fastest measurement rate available.

  6. 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.

  7. UK Scientists Help Solve Mystery Of Why Comets Emit X-Rays

    The mystery of why comets travelling through Space give off X-ray emissions has been solved thanks to new research undertaken by a team that included science staff from STFC’s Central Laser Facility (CLF) and RAL Space.

  8. Double Or Nothing: Astronomers Rethink Quasar Environment

    Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 "protoclusters," the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago, about ten times more than previously known.

  9. A Milestone In Petahertz Electronics

    In a semiconductor, electrons can be excited by absorbing laser light. Advances during the past decade enabled measuring this fundamental physical mechanism on timescales below a femtosecond (10-15 s).

  10. ‘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.
