As Sticky as a Gecko ... but Ten Times Stronger!
The gecko's amazing ability to stick to surfaces and walk up walls has inspired many researchers to manufacture materials that mimic the special surface of a gecko's foot. view more (2008-10-15)
Sandia researchers construct carbon nanotube device that can detect colors of the rainbow
Researchers at Sandia National Laboratories have created the first carbon nanotube device that can detect the entire visible spectrum of light, a feat that could soon allow scientists to probe single molecule transformations, study how those molecules respond to light, observe how the molecules change shapes, and understand other fundamental... view more...

Carbon nanotube membranes allow super-fast fluid flow
Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes' nearly friction-free surface. view more (2005-11-04)
Thin films of silicon nanoparticles roll into flexible nanotubes
By depositing nanoparticles onto a charged surface, researchers at the University of Illinois at Urbana-Champaign have crafted nanotubes from silicon that are flexible and nearly as soft as rubber. view more (2005-06-15)
New Techniques Pave Way for Carbon Nanotubes in Electronic Devices
Many of the vaunted applications of carbon nanotubes require the ability to attach these super-tiny cylinders to electrically conductive surfaces, but to date researchers have only been successful in creating high-resistance interfaces between nanotubes and substrates. view more (2006-11-07)
Radio waves fire up nanotubes embedded in tumors, destroying liver cancer
Cancer cells treated with carbon nanotubes can be destroyed by non-invasive radio waves that heat up the nanotubes while sparing untreated tissue, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center and Rice University has shown in preclinical experiments. view more (2007-11-02)
UB Engineers Prove That Carbon Nanotubes Are Superior to Metals for Electronics
In the quest to pack ever-smaller electronic devices more densely with integrated circuits, nanotechnology researchers keep running up against some unpleasant truths: higher current density induces electromigration and thermomigration, phenomena that damage metal conductors and produce heat, which leads to premature failure of devices. view more (2009-03-23)
UConn chemists find secret to increasing luminescence efficiency of carbon nanotubes
Chemists at the University of Connecticut have found a way to greatly increase the luminescence efficiency of single-walled carbon nanotubes, a discovery that could have significant applications in medical imaging and other areas. view more (2009-03-06)
Stable polymer nanotubes may have a biotech future
Scientists at the National Institute of Standards and Technology (NIST) have created polymer nanotubes that are unusually long (about 1 centimeter) as well as stable enough to maintain their shape indefinitely. view more (2006-02-03)
Nanotubes act as 'thermal Velcro' to reduce computer-chip heating
Engineers have created carpets made of tiny cylinders called carbon nanotubes to enhance the flow of heat at a critical point where computer chips connect to cooling devices called heat sinks, promising to help keep future chips from overheating. view more (2006-05-03)
