Nanotubes

Though our noses can detect suspicious smells at high levels, they can't discern every scent. Scientists have now developed an “electronic nose” that can pick up on the gases emitted by expired food, which they say is “better than human noses.”

Could tiny threads of carbon fiber do the same job as big metal industrial heating coils? A new breakthrough from researchers at Rice University says yes, and the finding could go a long way toward electrifying many manufacturing processes.

Carbon nanotubes have found use in everything from smart bandages to more efficient solar cells. Now, scientists at the University of Wisconsin-Madison have used them in a helmet lining foam that offers better impact protection than regular foams.

Engineers at EPFL have inserted carbon nanotubes into photosynthetic bacteria, greatly improving their electrical output. They even pass these nanotubes down to their offspring when they divide, through what the team calls “inherited nanobionics.”

Rice University researchers have produced a "smart" shirt that uses interwoven carbon nanotube fibers to provide steady electrical contact with the skin, allowing for ongoing gathering of data on heart activity.

Audeze helped design a pair of headphones to facilitate communication between doctor and patient during an MRI scan, without affecting the imagery produced. And this led to the development of the CRBN Electrostatic headphones for audiophiles.

MIT has developed a device that generates electricity using a completely new mechanism. “Particles” made of carbon nanotubes are dunked in an organic solvent, which induces a current to potentially power small robots or drive chemical reactions.

France's Nawa Technologies is setting up operations in the United States, and bringing its fast, affordable vertically aligned carbon nanotube (VACNT) manufacturing process into a new application: making carbon fiber composites much stronger.

Researchers have grown “forests” of carbon nanotubes (CNTs) longer than ever before. Using a new method, the team grew bunches of nanotubes up to 14 cm (5.5 in) long, which should help make it easier to scale up production of this versatile material.

French company Nawa technologies says it's already in production on a new electrode material that can radically boost the performance of existing and future battery types, delivering 3x the energy density, 10x the power, and vastly faster charging.

Graphene may be versatile, but it’s not all that good at dispersing in water. Now, researchers at Umeå University have found a relatively simple way to do it – use graphene oxide instead, which can then be used as a kind of graphene paint.

Ordinarily, when composite items are being manufactured, huge ovens and autoclaves have to be utilized. The production process could soon be much simpler, cheaper and more energy-efficient, however, thanks to the use of carbon nanotube films.
