Magnetism flicks switch on 'dark excitons'
In new experimental research appearing in this week's issue of Physical Review Letters, a Rice University-led team of nanoscientists and electrical engineers has flipped the switch on 'dark excitons' in carbon nanotubes by placing them inside a strong magnetic field. view more (2006-01-11)
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 find niche in electric switches
New research from Rice University and the University of Oulu in Oulu, Finland, finds that carbon nanotubes could significantly improve the performance of electrical commutators that are common in electric motors and generators. view more (2009-03-11)
Boston College scientists stretch carbon nanotubes
Physicists at Boston College have for the first time shown that carbon nanotubes can be stretched at high temperature to nearly four times their original length, a finding that could have implications for future semiconductor design as well as in the development of new nanocomposites. view more (2006-01-19)
Caltech scientists create titanium-based structural metallic-glass composites
Scientists from the California Institute of Technology (Caltech) have created a range of structural metallic-glass composites, based in titanium, that are lighter and less expensive than any the group had previously created, while still maintaining their toughness and ductility--the ability to be deformed without breaking. view more (2008-12-22)
Breakthrough in industrial-scale nanotube processing
Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. view more (2009-11-03)
Pitt Researchers Create Nontoxic Clean-up Method for Common, Potentially Toxic Nano Materials
University of Pittsburgh researchers have developed the first natural, nontoxic method for biodegrading carbon nanotubes, a finding that could help diminish the environmental and health concerns that mar the otherwise bright prospects of the super-strong materials commonly used in products, from electronics to plastics. view more (2008-12-17)
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)
Drug eluting nanostructured coatings enable targeted drug therapy for orthopedic patients
Drug delivery systems have progressed from the teaspoon to time-release capsules to drug-eluting stents. Nanotechnology promises yet another advance by delivering therapeutic agents at desired rates exactly where needed in the body. view more (2007-05-21)
Cells selectively absorb short nanotubes
DNA-wrapped single-walled carbon nanotubes (SWCNTs) shorter than about 200 nanometers readily enter into human lung cells and so may pose an increased risk to health, according to scientists at the National Institute of Standards and Technology (NIST). The results of their laboratory studies appear in an upcoming issue of Advanced Materials. view more (2007-04-02)
New biosensor can detect bacteria instantaneously
A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. view more (2009-09-09)
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)
Super sensitive gas detector goes down the nanotubes
When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases. view more (2009-01-14)
Nanotube-producing bacteria show manufacturing promise
Two engineers at the University of California, Riverside are part of a binational team that has found semiconducting nanotubes produced by living bacteria - a discovery that could help in the creation of a new generation of nanoelectronic devices. view more (2007-12-10)
NIST laser-based method cleans up grubby nanotubes
Before carbon nanotubes can fulfill their promise as ultrastrong fibers, electrical wires in molecular devices, or hydrogen storage components for fuel cells, better methods are needed for purifying raw nanotube materials. view more (2006-12-26)
On the path to metallic hydrogen
Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor. view more (2009-08-04)
Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the properties they need: add defects. view more (2008-06-17)
