But not all tiny tubes are made of carbon. For example, layers made of nanoscopic titanium dioxide have proven to be useful materials for biotechnology, catalytic converters, and solar cell technology. Although the semiconducting properties of these nanotubes are critical for many of these applications, their limited conductivity represents a hindrance for other areas of application. http://phys.org/news171613970.html Nanotechnology Tue, 08 Sep 2009 07:33:31 EST news171613970 An international team of researchers has designed a new graphite-based, magnetic nano-material that acts as a semiconductor and could help material scientists create the next generation of electronic devices like microchips. http://phys.org/news171126902.html Nanotechnology Wed, 02 Sep 2009 17:00:07 EST news171126902 (PhysOrg.com) -- Biomedical researchers at the University of Arkansas and University of Arkansas for Medical Sciences in Little Rock have developed a special contrast-imaging agent that is capable of molecular mapping of lymphatic endothelial cells and detecting cancer metastasis in sentinel lymph nodes.

A major problem, however, is that the metals used to grow nanotubes react unfavorably with materials found in circuits and composites. But now, researchers at MIT have for the first time shown that nanotubes can grow without a metal catalyst. The researchers demonstrate that zirconium oxide, the same compound found in cubic zirconia “fake diamonds,” can also grow nanotubes, but without the unwanted side effects of metal. http://phys.org/news169130384.html Nanotechnology Mon, 10 Aug 2009 13:40:20 EST news169130384 In his neatly ordered lab at DuPont, chemist Ming Zheng slides open a glass cabinet and removes a flask of soot that could have been swept from someone's fireplace. http://phys.org/news168613815.html Nanotechnology Tue, 04 Aug 2009 14:11:31 EST news168613815 (PhysOrg.com) -- "The terahertz regime has become of particular interest simply because it may allow us to look into materials in a completely new way," Diego Kienle tells PhysOrg.com.

The denser you pack, the quicker it spoils. The 10 to 100 gigabits of data per square inch on today’s memory cards has an estimated life expectancy of only 10 to 30 years.
