31. How Big Is The Alpha Particle? Laser Spectroscopy Provides New Results With Record Precision 2/4/2021

    The size of the alpha particle, the nucleus of the helium atom, has been measured more accurately than ever before. Results now indicate a size 1.67824(83) femtometers, which is 4.8 times more precise than previous measurements.

32. Long Live Superconductivity! Short Flashes Of Light With Sustaining Impact 2/4/2021

    Superconductivity – the ability of a material to transmit an electric current without loss – is a quantum effect that, despite years of research, is still limited to very low temperatures. Now a team of scientists at the MPSD has succeeded in creating a metastable state with vanishing electrical resistance in a molecular solid by exposing it to finely tuned pulses of intense laser light.

33. Switching Nanolight On And Off 2/4/2021

    A team of researchers led by Columbia University has developed a unique platform to program a layered crystal, producing imaging capabilities beyond common limits on demand.

34. An Optical Coating Like No Other 2/4/2021

    For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them.

35. Holography ‘Quantum Leap’ Could Revolutionise Imaging 2/4/2021

    A new type of quantum holography which uses entangled photons to overcome the limitations of conventional holographic approaches could lead to improved medical imaging and speed the advance of quantum information science.

    UCLA materials scientists and colleagues have discovered that perovskites, a class of promising materials that could be used for low-cost, high-performance solar cells and LEDs, have a previously unutilized molecular component that can further tune the electronic property of perovskites.

37. Extreme UV Laser Shows Generation Of Atmospheric Pollutant 2/3/2021

    An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and photochemical smog.

38. New Ink Jet Approach Offers Simple Way To Print Microdisk Lasers For Biosensing 2/3/2021

    Researchers have developed a unique inkjet printing method for fabricating tiny biocompatible polymer microdisk lasers for biosensing applications. The approach enables production of both the laser and sensor in a room temperature, open-air environment, potentially enabling new uses of biosensing technologies for health monitoring and disease diagnostics.

39. Dynamic 3D Printing Process Features A Light-Driven Twist 2/3/2021

    The speed of light has come to 3D printing. Northwestern University engineers have developed a new method that uses light to improve 3D printing speed and precision while also, in combination with a high-precision robot arm, providing the freedom to move, rotate or dilate each layer as the structure is being built.

40. Researchers Create Novel Photonic Chip 2/2/2021

    Researchers at the George Washington University and University of California, Los Angeles, have developed and demonstrated for the first time a photonic digital to analog converter without leaving the optical domain.
