Small nanoparticles bring big improvement to medical imaging (11/26/2009)

A joint research team, working at the National Institute of Standards and Technology and the National Institute of Allergy and Infectious Diseases, has discovered a method of using nanoparticles to illuminate the cellular interior to reveal the slow, complex processes taking place in a living cell. ...> Full Article

New nanostructure technology provides advances in eyeglass, solar energy performance (9/23/2009)

Chemical engineers at Oregon State University have invented a new technology to deposit "nanostructure films" on various surfaces, which may first find use as coatings for eyeglasses that cost less and work better. Ultimately, the technique may provide a way to make solar cells more efficiently produce energy. ...> Full Article

Nano measurement in the third dimension (7/7/2009)

Scientists at the Physikalisch-Technische Bundesanstalt have developed a metrological scanning probe microscope into a micro and nano coordinate measuring instrument. This now allows dimensional quantities with nanometer resolution also to be measured on three-dimensional objects in an extraordinarily large measurement range of 25 mm x 25 mm x 5 mm. ...> Full Article

Plasmonic whispering gallery microcavity paves the way to future nanolasers (1/26/2009)

The principle behind whispering galleries -- where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber -- has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers. Ultrasmall lasers, i.e., nanoscale, promise a wide variety of intriguing applications, including superfast communications and data handling (photonics), and optical microchips for instant and detailed chemical analyses. ...> Full Article

Researchers works toward 'smart' optical microchips (11/5/2007)

A new theory developed at MIT could lead to "smart" optical microchips that adapt to different wavelengths of light, potentially advancing telecommunications, spectroscopy and remote sensing. ...> Full Article

A hetero-structured ring discovered by nano-scientists (9/6/2007)

Teaming up with co-workers at home and abroad, researchers from the CAS affiliated National Center for Nanoscience and Technology (NCNST) recently succeeded in the fabricating a hetero-structured nano-ring in their laboratory. The work, which would be valuable for developing new optical or electronic nano-elements and related devices in the near future, was reported by Advanced Materials (Vol.19, 2319-2323, 2007). ...> Full Article
