| The simplest element: Turning hydrogen into 'graphene' Posted: 16 Dec 2014 09:38 AM PST New work delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures.  |
| Carbon-trapping 'sponges' can cut greenhouse gases Posted: 16 Dec 2014 09:38 AM PST In the fight against global warming, carbon capture -- chemically trapping carbon dioxide before it releases into the atmosphere -- is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, materials scientists have invented low-toxicity, highly effective carbon-trapping 'sponges' that could lead to increased use of the technology.  |
| Scientists trace nanoparticles from plants to caterpillars: Are nanoparticles getting in our food? Posted: 16 Dec 2014 09:38 AM PST In one of the most comprehensive studies of its kind, scientists tracked uptake and accumulation of quantum dot nanoparticles from water to plant roots, plant leaves and leaf-eating caterpillars.  |
| First steps for Hector the robot stick insect Posted: 16 Dec 2014 08:29 AM PST A research team has succeeded in teaching the only robot of its kind in the world how to walk.The robot is called Hector, and its construction is modeled on a stick insect. Inspired by the insect, Hector has passive elastic joints and an ultralight exoskeleton. What makes it unique is that it is also equipped with a great number of sensors and it functions according to a biologically inspired decentralized reactive control concept: the Walknet.  |
| Future batteries: Lithium-sulfur with a graphene wrapper Posted: 16 Dec 2014 08:27 AM PST What do you get when you wrap a thin sheet of the "wonder material" graphene around a novel multifunctional sulfur electrode that combines an energy storage unit and electron/ion transfer networks? An extremely promising electrode structure design for rechargeable lithium-sulfur batteries.  |
| Researchers generate tunable photon-pair spectrum using room-temperature quantum optics silicon chip Posted: 16 Dec 2014 07:07 AM PST A team of researchers have demonstrated a way to emit and control quantum light generated using a chip made from silicon -- one of the most widely used materials for modern electronics.  |
| Composite plane life cycle assessment shows lighter planes are the future Posted: 16 Dec 2014 07:05 AM PST A global fleet of composite planes could reduce carbon emissions by up to 15 percent, but the lighter planes alone will not enable the aviation industry to meet its emissions targets, according to new research.  |
| Self-repairing subsea material Posted: 16 Dec 2014 05:24 AM PST Embryonic faults in subsea high voltage installations are difficult to detect and very expensive to repair. Researchers believe that self-repairing materials could be the answer. The vital insulating material which encloses sensitive high voltage equipment may now be getting some 'first aid'.  |
