Thermal camouflage disguises hot and cold

ScienceDaily.com: Nanotechnology News - 27 июня, 2018 - 23:05
Hunters don camouflage clothing to blend in with their surroundings. But thermal camouflage - or the appearance of being the same temperature as one's environment - is much more difficult. Now researchers have developed a system that can reconfigure its thermal appearance to blend in with varying temperatures in a matter of seconds.

The ultimate 'smell test': Device sends rotten food warning to smartphones

ScienceDaily.com: Nanotechnology News - 27 июня, 2018 - 23:05
When it comes to the 'smell test,' the nose isn't always the best judge of food quality. Now scientists report that they have developed a wireless tagging device that can send signals to smartphones warning consumers and food distributors when meat and other perishables have spoiled. They say this new sensor could improve the detection of rotten food so it is tossed before consumers eat it.

Tricky feat with stand-up molecule

ScienceDaily.com: Nanotechnology News - 27 июня, 2018 - 23:04
Scientists have achieved a new level of precision working with single molecules. They succeeded in placing an ultrathin molecule in an upright position on a flat layer of silver atoms -- and the molecule remained standing instead of reverting to its naturally favored position. The artificial structure illustrates the potential of novel molecular fabrication methods.

Finding the right balance for catalysts in the hydrogen evolution reaction

ScienceDaily.com: Nanotechnology News - 27 июня, 2018 - 23:04
A collaboration has optimized the balance between the catalytic activity in hydrogen generation and stability of metal nanoparticles coated with different numbers of graphene layers. The team found that coating the catalyst nanoparticles with three to five graphene layers provided samples that displayed high catalytic activity in hydrogen evolution as well as high stability in acidic solution. These findings should aid the development of economical processes for large-scale hydrogen production.
