Smallest possible diamonds form ultra-thin nanothreads
Sun, 21 Sep 2014 14:51:18 EDT
For the first time, scientists have discovered how to produce ultra-thin 'diamond nanothreads' that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The threads have a structure that has never been seen before.
Engineered proteins stick like glue -- even in water
Sun, 21 Sep 2014 14:51:10 EDT
Researchers have found new adhesives based on mussel proteins could be useful for naval or medical applications. To create their new waterproof adhesives, researchers engineered bacteria to produce a hybrid material that incorporates naturally sticky mussel proteins as well as a bacterial protein found in biofilms -- slimy layers formed by bacteria growing on a surface. When combined, these proteins form even stronger underwater adhesives than those secreted by mussels.
New 'star' shaped molecule breakthrough
Sun, 21 Sep 2014 14:50:13 EDT
Scientists have generated a new star-shaped molecule made up of interlocking rings, which is the most complex of its kind ever created. Known as a 'Star of David' molecule, scientists have been trying to create one for over a quarter of a century.
Uncovering the forbidden side of molecules: Infrared spectrum of charged molecule seen for first time
Sun, 21 Sep 2014 14:50:11 EDT
Researchers have succeeded in observing the “forbidden” infrared spectrum of a charged molecule for the first time. These extremely weak spectra offer perspectives for extremely precise measurements of molecular properties and may also contribute to the development of molecular clocks and quantum technology.
Fracking's environmental impacts scrutinized
Sun, 21 Sep 2014 09:29:38 EDT
Greenhouse gas emissions from the production and use of shale gas would be comparable to conventional natural gas, but the controversial energy source actually fared better than renewables on some environmental impacts, according to new research.
