  • New material for splitting water

    Solar energy is clean and abundant. But when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis -- in which solar energy is used to make fuels. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen. The hydrogen and more

  • X-rays from tabletop lasers allows scientists to peer through the 'water window'

    Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays. The technique means advanced measurements of fast reactions will now be possible in physics labs around the world, without having to wait to use expensive and s more

  • Long-distance relationships of particles: Electron-hole pairs in two-dimensional crystals

    When light of specific frequency hits a semiconductor crystal, it is absorbed and produces a excitation, a state of higher energy. In solar cells, this energy can be converted into electricity and used. In two-dimensional crystals, which consist of only a few atomic layers, so called “excitons” are more
