A Queen's University Belfast scientist has recreated the first ever mini version of a gamma ray burst in a laboratory, opening up a whole new way to investigate their properties and potentially unlocking some of the mysteries around alien civilisation.
Developed by UZH researchers, the algorithm DroNet allows drones to fly completely by themselves through the streets of a city and in indoor environments. Therefore, the algorithm had to learn traffic rules and adapt training examples from cyclists and car drivers.
NICT developed a simple miniaturized atomic clock system, which does not require a complicated frequency multiplication, as an outcome of a collaboration with Tohoku University and Tokyo Institute of Technology. We propose a new microwave generator that exploits thickness extensional vibration in a piezoelectric thin film to miniaturize an atomic clock. By transferring this technology into practical products, atomic clocks, which are deployed in high-end systems such as satellites, can be incorporated on smartphones.
An international team of scientists has produced the first high-powered, randomly polarised laser beam with a 'Q switch' laser, which typically emits pulses of light so brief that they're measured in nanoseconds. Lasers are a critical part of modern technology--they're used in everything from our automobiles to medical equipment to the satellites orbiting Earth. Now, researchers are broadening the potential applications of even smaller and more powerful lasers. The researchers published their results in Scientific Reports, an open-access Nature journal.
A Northwestern University research team used inverse design principles and a 3-D printer to create highly efficient broadband metadevices at millimeter-wave frequencies that could prove revolutionary for consumer products, defense, and telecommunications.
Researchers at have designed and fabricated the world's smallest electro-optic modulator, which could mean major reductions in energy used by data centers and supercomputers.
Researchers have, for the first time, used a material's persistent photoconductivity to stimulate neurotype cells. The technique, which is relatively simple, should facilitate future research on using charge to influence cellular behavior.
Extremely fine porous structures with tiny holes -- resembling a kind of sponge at nano level -- can be generated in semiconductors. This opens up new possibilities for the realization of tiny sensors or unusual optical and electronic components. There have already been experiments in this area with porous structures made from silicon. Now, researchers at TU Wien have succeeded in developing a method for the controlled manufacture of porous silicon carbide.
Fine tuning the composition of nitride alloys can further the development of optical and electronic interface devices.
Illinois researchers have demonstrated that sound waves can be used to produce ultraminiature optical diodes that are tiny enough to fit onto a computer chip. These devices, called optical isolators, may help solve major data capacity and system size challenges for photonic integrated circuits, the light-based equivalent of electronic circuits, which are used for computing and communications.
