Scientists have produced a three-dimensional structure with long-range magnetic order by combining a two-dimensional layer magnet and a one-dimensional columnar magnetic system. In the resulting pillared layer framework, the pillars determine the interactions between individual layers, enabling spontaneous magnetization.

Solar cells can only use photons with energies above a specific threshold to generate electricity. A German-Australian research collaboration has now combined solar cells with an organic material which can 'add up' low-energy photons to yield higher-energy light, which can then be harvested by the solar cell.

Read moreNew catalysts have potential to greatly reduce processing costs in future fuels like hydrogen. The catalysts are composed of a unique structure of single gold atoms bound by oxygen to sodium or potassium atoms, supported on non-reactive silica materials. They demonstrate comparable activity and stability with catalysts comprising precious metal nanoparticles on rare earth and other reducible oxide supports when used in producing highly purified hydrogen.

For several years, it has been known that superfluid helium housed in reservoirs located next to each other acts collectively, even when the channels connecting the reservoirs are too narrow and too long to allow for substantial flow. A new theoretical model reveals that the phenomenon of mysterious communication 'at a distance' between fluid reservoirs is much more common than previously thought.
