  • Silicon as a semiconductor: silicon carbide would be much more efficient

    In power electronics, semiconductors are based on the element silicon – but the energy efficiency of silicon carbide would be much higher. Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what exactly is preventing the use of this combination of silicon and carbon i more

  • Extracting clean fuel from sunlight

    Securing enough energy to meet human needs is one of the greatest challenges society has ever faced. Previously reliable sources--oil, gas and coal--are degrading air quality, devastating land and ocean and altering the fragile balance of the global climate, through the release of CO2 and other gree more

  • Search for new semiconductors heats up with gallium oxide

    University of Illinois electrical engineers have cleared another hurdle in high-power semiconductor fabrication by adding the field's hottest material - beta-gallium oxide - to their arsenal. Beta-gallium oxide is readily available and promises to convert power faster and more efficiently than today more

A Basic Guide to How LED Lights Work

Christmas isn’t far off now, and whether you’re celebrating it or not, you’ve may well have started seeing Christmas lights starting to appear adorning houses and Christmas trees. How do these lights actually work, and how can they be made to produce such an array of colours? This graphic takes a lo more

The Chemical Elements of a Smartphone

There are an isolated few graphics online that look at elements involved in the manufacture of a smartphone – for example, this ‘Periodic Table of iPhones’ – but there’s actually remarkably little easily accessible information out there that details the specific compounds used for specific purposes more
