Black is black, right? Not so, according to a team of NASA engineers now developing a blacker-than pitch material that will help scientists gather hard-to-obtain scientific measurements or observe currently unseen astronomical objects, like Earth-sized planets in orbit around other stars.The nanotech-based material now being developed by a team of 10 technologists at the NASA Goddard Space Flight Center in Greenbelt, Md., is a thin coating of multi-walled carbon nanotubes "” tiny hollow...

Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a new class of computers and electronics that are faster and consume less power than today's. The semiconducting nanostructures might be used to revolutionize electronics by replacing conventional silicon components and circuits. However, one obstacle in their application is that metallic versions form unavoidably during the...

Efforts to store energy in carbon nanotubes described at AVS Meeting in Albuquerque When weighing options for energy storage, different factors can be important, such as energy density or power density, depending on the circumstances. Generally batteries -- which store energy by separating chemicals -- are better for delivering lots of energy, while capacitors -- which store energy by separating electrical charges -- are better for delivering lots of power (energy per time). It would be nice,...

Twisting spires, concentric rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can make from carbon nanotubes using a new manufacturing process. The process is called "capillary forming," and it takes advantage of capillary action, the phenomenon at work when liquids seem to defy gravity and travel up a drinking straw of their own accord. The new miniature shapes, which are difficult if not impossible to build using any...

Carbon nanotubes "” those tiny particles poised to revolutionize electronics, medicine, and other areas "” are much bigger in the strength department than anyone ever thought, scientists are reporting. 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, the material used in bulletproof vests and other products. The findings, which could...

Speakers made from carbon nanotube sheets that are a fraction of the width of a human hair can both generate sound and cancel out noise -- properties ideal for submarine sonar to probe the ocean depths and make subs invisible to enemies. That's the topic of a report on these "nanotube speakers," which appears in ACS' Nano Letters, a monthly journal. Ali Aliev and colleagues explain that thin films of nanotubes can generate sound waves via a thermoacoustic effect. Every time that an electrical...

Rice researchers' method untangles long tubes, clears hurdle toward armchair quantum wire Rice University scientists have found the "ultimate" solvent for all kinds of carbon nanotubes (CNTs), a breakthrough that brings the creation of a highly conductive quantum nanowire ever closer. Nanotubes have the frustrating habit of bundling, making them less useful than when they're separated in a solution. Rice scientists led by Matteo Pasquali, a professor in chemical and biomolecular engineering...

The silicon transistors in your computer may be replaced in ten years by transistors based on carbon nanotubes. This is what scientists at the University of Gothenburg are hoping "“ they have developed a method to control the nanotubes during production. Silicon is subject to certain limitations, and industry is looking for a replacement. The electronics industry has net annual sales of over USD 200 billion, and this means that the development is being fuelled by powerful forces. Carbon...

Rice researchers print field-effect transistors with nano-infused ink Rice University researchers have discovered thin films of nanotubes created with ink-jet printers offer a new way to make field-effect transistors (FET), the basic element in integrated circuits. While the technique doesn't exactly scale down to the levels required for modern microprocessors, Rice's Robert Vajtai hopes it will be useful to inventors who wish to print transistors on materials of any kind, especially on...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
