| New material makes water and oil roll off Posted: 28 Nov 2014 05:06 AM PST Car finish, to which no dirt particles adhere, house fronts, from which graffiti paints roll off, and shoes that remain clean on muddy paths – the material "fluoropore" might make all this possible. Both water and oil droplets roll off this new class of highly fluorinated super-repellent polymers.  |
| Single-atom gold catalysts may offer path to low-cost production of fuel and chemicals Posted: 27 Nov 2014 06:23 PM PST New catalysts designed and investigated by engineering researchers 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.  |
