| LEDs made from 'wonder material' perovskite Posted: 05 Aug 2014 10:21 AM PDT Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future. A hybrid form of perovskite -- the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon -- has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible color displays.  |
| Surprise discovery could see graphene used to improve health Posted: 05 Aug 2014 10:20 AM PDT A chance discovery about the 'wonder material' graphene -- already exciting scientists because of its potential uses in electronics, energy storage and energy generation -- takes it a step closer to being used in medicine and human health.  |
| Posted: 04 Aug 2014 12:14 PM PDT Materials that are firmly bonded together with epoxy and other tough adhesives are ubiquitous in modern life -- from crowns on teeth to modern composites used in construction. Yet it has proved remarkably difficult to study how these bonds fracture and fail, and how to make them more resistant to such failures. New research reveals how bonded materials, from airplane wings to dental crowns, lose their bonding.  |
| Minuscule chips for NMR spectroscopy promise portability, parallelization Posted: 04 Aug 2014 12:12 PM PDT Engineers have created a truly portable device for nuclear magnetic resonance (NMR) spectroscopy.  |
