| Switching to vehicles powered by electricity from renewables could save lives Posted: 15 Dec 2014 03:53 PM PST Driving vehicles that use electricity from renewable energy instead of gasoline could reduce the resulting deaths due to air pollution by 70 percent. This finding comes from a new life cycle analysis of conventional and alternative vehicles and their air pollution-related public health impacts. The study also shows that switching to vehicles powered by electricity made using natural gas yields large health benefits.  |
| Posted: 15 Dec 2014 03:50 PM PST A key discovery to understanding Roman architectural concrete that has stood the test of time and the elements for nearly two thousand years has been made by researchers using beams of X-rays.  |
| Lead islands in a sea of graphene magnetize the material of the future Posted: 15 Dec 2014 09:29 AM PST Researchers have discovered that if lead atoms are intercalated on a graphene sheet, a powerful magnetic field is generated by the interaction of the electrons' spin with their orbital movement. This property could have implications in spintronics, an emerging technology to create advanced computational systems. Graphene is considered the material of the future due to its extraordinary optical and electronic mechanical properties, especially because it conducts electrons very quickly. However, it does not have magnetic properties, and thus no method has been found to manipulate these electrons or any of their properties to use it in new magnetoelectronic devices.  |
| Squid supplies blueprint for printable thermoplastics Posted: 15 Dec 2014 08:45 AM PST Squid, what is it good for? You can eat it and you can make ink or dye from it, and now a team of researchers is using it to make a thermoplastic that can be used in 3-D printing.  |
| Live 3-D images to be taken from inside materials Posted: 15 Dec 2014 05:46 AM PST X-rays are a tried and tested way to investigate components and materials. Researchers are now developing an X-ray detector capable of delivering particularly high-quality 3-D images in real time. This will make it possible to precisely reconstruct even the processes going on inside materials and e.g. provide a reliable way of detecting minoscule faults.  |
