Tiny Tubes May Trumpet End of Bulky Loudspeakers

Nanotube technology could allow for speakers on clothes, windows, screens

(Newser) - You may soon be able to add paper-thin speakers to that flat-panel TV, the Economist reports. Scientists have used ultra-tiny carbon nanotubes to make a transparent film that produces sound identical to a signal-carrying current that passes through it. If the technology can be made commercially viable, you might be... More »

Nanotech Cancer Risk Seen

Nanotubes, widely used 'wonder particles,' could have asbestos-like effect

(Newser) - Researchers have found that microscopic “wonder particles” used in a small number of materials, including bicycle parts and bumpers, have asbestos-like effects if inhaled, the Los Angeles Times reports. Consumers aren’t really at risk from the carbon nanotubes, but factory workers making the products could be, the researchers... More »

Really Black Is the New Black

Scientists create darkest black ever, and it may have practical uses

(Newser) - What's the blackest thing you can think of? If you said a carpet of carbon nanotubes, you probably work with a Rice University team of scientists whose current project is "pushing the limit of how much light can be absorbed into one material." Their new material could lead... More »

Scientists Roll Out Paper Batteries

We're hoping for fold-able cell phones

(Newser) - Scientists have come up with a paper-like substance that can act as a power source, Scientific American reports. The thin, flexible substance—composed of cellulose, carbon nanotubes, and liquid salts—can be used as both a battery and a supercapacitor, which can deliver quick bursts of high power. What's more,... More »
