Nanotube coating helps shrink mass spectrometers

Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety.

Caps not the culprit in nanotube chirality

(Phys.org) —A single-walled carbon nanotube grows from the round cap down, so it's logical to think the cap's formation determines what follows. But according to researchers at Rice University, that's not entirely so.

Carbon nanotube fibers outperform copper

(Phys.org) —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.

Cooling microprocessors with carbon nanotubes

"Cool it!" That's a prime directive for microprocessor chips and a promising new solution to meeting this imperative is in the offing. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...

How to tap the sun's energy through heat as well as light

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 ...

Scientists scale terahertz peaks in nanotubes

(Phys.org) —Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they're metallic by nature or doped.
