New composite material made of carbon nanotubes

ScienceDaily.com: Nanotechnology News - 22 ноября, 2017 - 19:30
Due to their unique properties, carbon nanotubes would be ideal for numerous applications, but to date they cannot be combined adequately with other materials, or they lose their beneficial properties. Scientists have developed an alternative method of combining, so they retain their characteristic properties. As such, they 'felt' the thread-like tubes into a stable 3-D network.

Monitor your UV exposure with an adhesive nanoplasmonic patch

Nanowerk.com - 22 ноября, 2017 - 16:33
Moderate exposure to sunlight has significant health benefits, however, exposure to ultraviolet (UV) radiation also is a major risk factor for most skin cancers. That means that, while moderate exposure to sunlight is recommended, there is a fine line to walk between beneficial and harmful amounts of UV exposure. To take the guesswork out of assessing the exposure to damaging UV rays, several wearable consumer UV sensors have already hit the market. Researchers have now proposed a simple and low-cost stick-on nanoplasmonic patch made of optically active silver nanoparticles embedded in a film of nanopaper. The patch changes color once it has been exposed to a certain amount of UV light.

Fine felted nanotubes - a new composite material made of carbon nanotubes

Nanowerk.com - 21 ноября, 2017 - 22:24
Carbon nanotubes (CNTs) either cannot be combined adequately with other materials, or if they can be combined, they then lose their beneficial properties. Scientists have now developed an alternative method, with which CNTs can be combined with other materials, so that they retain their characteristic properties.

Nano-watch has steady hands

ScienceDaily.com: Nanotechnology News - 21 ноября, 2017 - 21:25
A new nanomechanical hand shows the time of an electronic clock, by spinning a tiny cylinder using light. A silicon nanorod, less than a thousandth of a millimetre long, can be trapped in thin air using focused laser beams, and spun to follow the ticking of a clock, losing only one-millionth of a second over four days.
