14-10-17 researchers from columbia engineering and the georgia institute of technology report today that they have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (mo...

14-09-29 electricity and magnetism rule our digital world. semiconductors process electrical information, while magnetic materials enable long-term data storage. a university of pittsburgh research team has discovered a way to fuse these two distinct propert...

14-02-24 selecting a chevy volt, tesla model s, nissan leaf -- or one of many other new models -- shoppers in the united states bought more than 96,000 plug-in electric cars in 2013. that's a tiny slice of the auto market, but it's up eighty-four percent fro...

13-03-29 like tiny, crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields -- but in opposite directions, scientists at the university of california, davis, have found. their results, published april 8...

13-02-25 flowers' methods of communicating are at least as sophisticated as any devised by an advertising agency, according to a new study, published february 21 in science express by researchers from the university of bristol. however, for any advertisement...

12-04-20 a new genre of electric power-generating stations could supply electricity for more than a half billion people by tapping just one-tenth of the global potential of a little-known energy source that exists where rivers flow into the ocean, a new anal...

11-10-12 physicists have predicted that under the influence of sufficiently high electric fields, liquid droplets（液滴） of certain materials will undergo solidification, forming crystallites at temperature and pressure conditions that correspond to liquid...

11-06-24 chubu electric, japan's third biggest utility, will receive an emergency loan to purchase alternative sources of power, as the country continues to face a shortage. 日本第三大电力公司中部电力公司将收到一笔紧急贷款用于购买替代性能源，目前日本面临持续...
