  • Blue-emitting diode demonstrates limitations and...
    on January 24, 2020 at 5:00 am

    (University of California - Berkeley) Halide perovskites have garnered attention because they're highly efficient at capturing energy in solar cells and efficient emitters in diodes. But researchers failed at making perovskite LEDs that emit blue light. UC Berkeley chemists succeeeded, but X-ray studies of the LED's structure show that it's very sensitive to temperature, humidity and chemical environment. Hence environmental and chemical control is essential for stable operation. But these […]

    (RMIT University) Taking a thin film common in cell phone touchscreens, researchers have used liquid metal chemistry to shrink it from 3D to 2D. The ultra-thin and ultra-flexible electronic material could be printed and rolled out like newspaper, for the touchscreens of the future.

  • What goes up may actually be down
    on January 24, 2020 at 5:00 am

    (Frontiers) A new study in Frontiers in Neuroscience used virtual reality to determine how people plan their movements by 'seeing' gravity using visual cues in the landscape around them, rather than 'feeling it' through changes in weight and balance.

    on January 24, 2020 at 5:00 am

    (Stanford School of Engineering) The adoption of wearable electronics has so far been limited by their need to derive power from bulky, rigid batteries that reduce comfort and may present safety hazards due to chemical leakage or combustion. Stanford researchers have developed a soft and stretchable battery that relies on a special type of plastic to store power more safely than the flammable formulations used in conventional batteries today.

    on January 24, 2020 at 5:00 am

    (GRID-Arendal) GRID-Arendal has launched the Global Tailings Portal, a new public, searchable database with detailed information on more than 1,700 mine tailings dams around the world. The data are based on disclosures provided by mining companies following a request from the Church of England Pensions Board and the Swedish National Pension Funds' Council of Ethics. The portal is designed to be used by scientists, governments, insurers, the finance community, the mining industry, media, and […]
