Recent materials stuff that intrigued me

* The Quest for a New Class of Superconductors — exploration of materials for higher temp superconductivity — basically trying to find materials that conduct without involving phonons
* Silicon nanowire battery with much greater energy density. One example of how messing with the nanostructure of materials can have remarkable impacts
* Materials with no thermal expansion
* Nanorods as measurement devices — measuring cell ph
* extra strong metallic foams — another instance of how messing with nano structure can have remarkable macro effects
* Turning diamonds into conducters
* High performance carbon nanotube fibers.
