| Posted: 25 Jul 2014 08:07 AM PDT Scientists have achieved an electrical current of 100,000 amperes, which is by far the highest in the world, by using the new idea of assembling the state-of-the-art yttrium-based high-temperature superconducting tapes to fabricate a large-scale magnet conductor.       |
| New system to detect mercury in water systems Posted: 25 Jul 2014 08:07 AM PDT A new ultra-sensitive, low-cost and portable system for detecting mercury in environmental water has been developed by researchers. "The promising sensing performance of this system along with its cost-competiveness and portability make it an excellent potential alternative to current analytical techniques," says the project's leader. "This technique could provide the basis for future point-of-analysis systems for monitoring water quality on site and may help implement better monitoring processes around the world."  |
| Breakthrough laser experiment reveals liquid-like motion of atoms within an ultra-cold cluster Posted: 25 Jul 2014 05:03 AM PDT A new study has furthered our understanding of how tiny nanosystems function, unlocking the potential to create new materials using nanosized 'building blocks'.  |
| Physicists create tool to foresee language destruction impact and thus prevent it Posted: 25 Jul 2014 05:03 AM PDT Researchers defined parameters that estimate the speed of regression of a native language when replaced by one of its neighboring languages. The study focused on the case of Welsh. In a wider context, this type of model could be applied to other examples of cultural changes in which the more favorable traits expand and abolish the predominance of a native cultural trait.  |
| Steam energy from the sun: New spongelike structure converts solar energy into steam Posted: 24 Jul 2014 06:39 PM PDT A new material structure generates steam by soaking up the sun. The structure -- a layer of graphite flakes and an underlying carbon foam -- is a porous, insulating material structure that floats on water. When sunlight hits the structure's surface, it creates a hotspot in the graphite, drawing water up through the material's pores, where it evaporates as steam. The brighter the light, the more steam is generated.  |
