| Manipulating complex molecules by hand Posted: 06 Nov 2014 07:40 AM PST Scientists have developed a new control technique for scanning probe microscopes that enables the user to manipulate large single molecules interactively using their hands. Until now, only simple and inflexibly-programmed movements were possible. To test their method, the researchers 'stenciled' a word into a molecular monolayer by removing 47 molecules. The process opens up new possibilities for the construction of molecular transistors and other nanocomponents. |
| How to make mobile batteries last longer by controlling energy flows at nano-level Posted: 06 Nov 2014 05:26 AM PST Electronic devices waste a lot of energy by producing useless heat. This is one of the main reasons our mobiles use up battery power so quickly. Researchers have now made a leap forward in understanding how this happens and how this waste could be reduced by controlling energy flows at a molecular level. This would make our technology cheaper to run and more durable. |
| The world’s most advanced bionic hand Posted: 06 Nov 2014 05:26 AM PST A prosthetic hand, which provides a sense of touch acute enough to handle an egg, has been completed and is now exploited by the NEBIAS project after 10 years of research. The world's most advanced bionic hand was tested with the help of amputee Dennis Aabo Sørensen who was able to grasp objects intuitively and identify what he was touching, while blindfolded. |
| 'Direct writing' of diamond patterns from graphite a potential technological leap Posted: 05 Nov 2014 05:35 PM PST What began as research into a method to strengthen metals has led to the discovery of a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips. |
