In 'novel playground,' metals are formed into porous nanostructures

June 27, 2008 | User rating: 4.9 / 5 after 20 vote(s) | User comments: 3

For 5,000 years or so, the only way to shape metal has been to "heat and beat." Even in modern nanotechnology, working with metals involves carving with electron beams or etching with acid.


Gold, DNA Combination May Lead To Nano-Sensor

July 01, 2008 | User rating: 4.8 / 5 after 9 vote(s) | No comments yet

The ability to use genetic material to assemble nanoscopic particles of gold could be an important step toward creating tiny “spies” that will be able to infiltrate individual cells and report back in real time on the cell’s ...


Controlled growth of truly nanoscale single crystal fullerites for device applications

July 14, 2008 | User rating: 4.8 / 5 after 8 vote(s) | No comments yet

(PhysOrg.com) -- University of Surrey researchers have found a way to make ultra-small pure carbon crystals entirely formed from the spherical carbon ‘buckyball’ molecule known as C60. The method used involves mixing two ...
