The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one-sixth, which can significantly improve the energy efficiency of lighting systems.
In a paper to be published in a forthcoming issue of TECHNOLOGY, a consortium of researchers from Portugal have successfully conducted a proof-of-concept experiment to produce a new blood-derived product by application of pulsed electric fields (PEF) to platelet concentrates (PC) with no therapeutic value for transfusion medicine. This process guarantees the valorization of a blood-derived component that would otherwise be discarded.
Researchers from Osaka University developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating.
An international team of scientists from the National University of Science and Technology 'MISIS' (NUST MISIS), Tianjin University (China), as well as from Japan and the United States has developed new energy-efficient iron-based alloys which combine high mechanical and magnetic properties with low cost and open up new opportunities for industry. The research results are published in the Journal of Alloys and Compounds.
Future high-speed communication networks based on millimeter-wave (30-300GHz) technology will be more robust and efficient in delivering extremely high speed, high quality video, and multimedia content and services thanks to the results of a ground-breaking research project. The recently concluded project was a collaboration between Huawei Technologies and IMDEA Networks Institute, the Madrid-based research body pioneering many technologies that are being deployed in the new 5G landscape.
Japanese scientists at Tokyo University of Agriculture and Technology and Yokohama National University have identified the molecular mechanism that gives the skin secretions of a species of frog effective antimicrobial properties. Unravelling the molecular mechanism that facilitates antimicrobial activity of these peptides can help us better understand how the defense system of the frog has evolved, and how this can be used to fight microbial infections of medical importance.
Atomic beams conjure fantasies of gigantic Space Force canons. But there are real tiny atomic beams that shoot out of newly engineered collimators, a kind of tiny silicon peashooter, that could land in handheld devices. The beams streaming out of them create precise inertia much better than a gyroscope's that could help spacecraft navigate the solar system. The atomic beams from the new collimators could also let physicist cheaply and easily produce exotic quantum mechanical states.
Superinjection, the effect used in lasers and LEDs creation can work in 'pure' semiconductors, which was previously considered impossible. This opens up new prospects for designing highly efficient blue, violet, ultraviolet, and white LEDs, as well as light sources for optical wireless communication (Li-Fi), new types of lasers, transmitters for the quantum internet, and optical devices for early disease diagnostics.
New research shows how Cooper pairs -- quasiparticles that make superconductivity possible -- can also play an opposite role in an exotic type of insulating materials known as Cooper pair insulators.
A pioneering tagging system that monitors the movement and local environment of sea animals reaches deeper depths and higher sensitivities.
