Self-Healing Metal Oxides Could Protect Against Corrosion

Self-healing metal oxides could protect against corrosion. Researchers find an ultrathin layer of aluminum oxide, though solid, can flow like a liquid instead of cracking. Researchers have found that a solid oxide protective coating for metals can, when applied in sufficiently thin layers, deform as if it were a liquid, filling any cracks and gaps

Engineered “Sand” May Help Cool Electronic Devices

Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry electronic devices. The silicon dioxide doesn”t do the cooling itself. Instead, the unique surface properties of the coated nanoscale material conduct the heat
