Researchers from the National Institute of Standards and Technology (NIST) and the Food and Drug Administration (FDA) have demonstrated that they can make sensitive chemical analyses of minute samples of nanoparticles by, essentially, roasting them on top of a quartz crystal. The ...
Tests show bundles beat traditional cables for transmitting electricity
On a pound-per-pound basis, carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass, according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than ...
Researchers find the unusual movement of water molecules through carbon nanotubes explains their faster-than-expected travel times
Cars inch forward slowly in traffic jams, but molecules, when jammed up, can move extremely fast. New research by Northwestern University researchers finds that water molecules traveling through tiny carbon nanotube pipes do not flow continuously but rather intermittently, like stop-and-go ...
New approach developed at MIT could generate power from sunlight efficiently and on demand
A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the ...
Experimental evidence and computer simulations suggest how to grow structures with the best trade offs between 3 desired characteristics: strength, flexibility and the ability to dissipate heat
When engineers design devices, they must often join together two materials that expand and contract at different rates as temperatures change. Such thermal differences can cause problems if, for instance, a semiconductor chip is plugged into a socket that can't expand and contract rapidly ...
University of Illinois researchers have developed a way to heal gaps in wires too small for even the world’s tiniest soldering iron. Led by electrical and computer engineering professor Joseph Lyding and graduate student Jae Won Do, the Illinois team published its results in the journal Nano ...
Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous ...
A discovery at Rice University aims to make vehicles that run on compressed natural gas more practical. It might also prolong the shelf life of bottled beer and soda. The Rice lab of chemist James Tour has enhanced a polymer material to make it far more impermeable to pressurized gas and far ...
Basic device validates CNTs as potential successors to silicon semiconductors
A team of Stanford engineers has built a basic computer using carbon nanotubes, a semiconductor material that has the potential to launch a new generation of electronic devices that run faster, while using less energy, than those made from silicon chips. This unprecedented feat culminates ...
New technique could one day help improve the performance of microelectronics in devices ranging from batteries to spacecraft
Carbon nanotubes' outstanding mechanical, electrical and thermal properties make them an alluring material to electronics manufacturers. However, until recently scientists believed that growing the high density of tiny graphene cylinders needed for many microelectronics applications would be ...
