I-Micronews - NANOMATERIALS TECHNO: Carbon nanotubes twice as strong as once thought...

I-Micronews - NANOMATERIALS TECHNO: Carbon nanotubes twice as strong as once thought... New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar

I-Micronews - NANOMATERIALS TECHNO: Surface materials: Super clean glass... Gao Han and co-workers at the A*STAR Institute of Materials Research and Engineering1 have now fabricated a transparent palladium-functionalized TiO2 nanotube array on a glass substrate. They studied how the photocatalytic activity of the TiO2 nanotube array changes as the wall thickness or height of the nanotubes was adjusted, and identified the nanotube configuration that gave the highest photocatalytic activity.

Space Colonists Could Use Bacteria to Mine Minerals on Mars and the Moon: Scientific American

Space Colonists Could Use Bacteria to Mine Minerals on Mars and the Moon: Scientific American Microbes currently are used in mining to help recover metals such as gold, copper and uranium. Now researchers suggest bacteria could be enlisted for "bio-mining" in space, to extract oxygen, nutrients and minerals from extraterrestrial bodies such as the moon and Mars for use by future colonists there.

I-Micronews - NANOMATERIALS TECHNO: Pushing ions through carbon nanotubes...

I-Micronews - NANOMATERIALS TECHNO: Pushing ions through carbon nanotubes... For the first time, a team of MIT chemical engineers has observed single ions marching through a tiny carbon-nanotube channel. Such channels could be used as extremely sensitive detectors or as part of a new water-desalination system. They could also allow scientists to study chemical reactions at the single-molecule level.

Why implant coatings detach: Nanocorrosion causes implants to fail

Why implant coatings detach: Nanocorrosion causes implants to fail: "Whether on computer hard disks, saw blades, embossing tools, razor blades or fuel-injection nozzles, extremely hard coatings made of diamond-like carbon (DLC) have proven their value over and over again. They reduce wear and thereby give tools and components a longer operating lifetime."

Nano-architectured aluminum has steely strength

Nano-architectured aluminum has steely strength: "ScienceDaily (Sep. 8, 2010) — A North Carolina State University researcher and colleagues have figured out a way to make an aluminum alloy, or a mixture of aluminum and other elements, just as strong as steel."

Novel nanotechnology collaboration leads to breakthrough in cancer research

Novel nanotechnology collaboration leads to breakthrough in cancer research: "A multidisciplinary research group at UCLA has now teamed up to not only visualize a virus but to use the results to adapt the virus so that it can deliver medication instead of disease."
