Animated movie of ice
— 8 Jan 2008 17:30 | ChemistryAn animated movie shows an ordered structure dissolving little by little into a disordered mess after a light pulse: Swedish researchers from the University of Uppsala have used a computer…
Strange-behaving crystals could have impact on research and technology
— 3 Jan 2008 21:38 | ChemistryAll of us break the rules from time to time - even crystals. 'There are all sorts of rules about what crystals can do during phase transitions,' said Mark D. Hollingsworth, associate…
Smaller is stronger, now scientists know why
— 2 Jan 2008 21:28 | PhysicsAs structures made of metal get smaller - as their dimensions approach the micrometre scale (millionths of a metre) or less - they get stronger. Scientists discovered this phenomenon…
