For nanowires, nothing sparkles quite like diamond (2/19/2010)

Diamonds are renowned for their seemingly flawless physical beauty and their interplay with light. Now researchers are taking advantage of the mineral's imperfections to control that light at the atomic scale, generating one photon at a time. ...> Full Article

Digging deep into diamonds, applied physicists advance quantum science and technology (2/15/2010)

By creating diamond-based nanowire devices, a team at Harvard has taken another step towards making applications based on quantum science and technology possible. The new device offers a bright, stable source of single photons at room temperature, an essential element in making fast and secure computing with light practical. ...> Full Article

New nanocrystalline diamond probes overcome wear (11/12/2009)

Researchers at the McCormick School of Engineering and Applied Science at Northwestern University have developed, characterized, and modeled a new kind of probe used in atomic force microscopy, which images, measures, and manipulates matter at the nanoscale. Using diamond, researchers made a much more durable probe than the commercially available silicon nitride probes, which are typically used in AFM to gather information from a material, but can wear down after several uses. ...> Full Article
