14-07-26 A novel combination of microscopy（显微镜检查） and data processing has given researchers at the Department of Energy's Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemic...

14-07-10 Iraq has warned the UN that Sunni militants have seized nuclear materials used for scientific research at a university in the city of Mosul. 伊拉克向联合国发出警告，逊尼派武装分子已经从摩苏尔一所大学获得了用于科研的核材料。 In a letter seen by Reute...

14-06-05 Mussels（贻贝） might be a welcome addition to a hearty（丰盛的） seafood stew（炖汤） , but their notorious ability to attach themselves to ships' hulls（外壳） , as well as to piers（防洪堤） and moorings（系泊设备） , makes them an unwelcome sigh...

14-06-03 Writing in Nature Physics, a large international team led by Dr Artem Mishchenko and Sir Andre Geim from The University of Manchester shows that the electronic properties of graphene change dramatically if graphene is placed on top of boron nitride...

14-04-23 Stem cells -- the body's master cells -- demonstrate a bizarre property never before seen at a cellular level, according to a study published today from scientists at the University of Cambridge. The property -- known as auxeticity（拉胀性） -- is o...

14-04-15 Some 2 to 5 percent of all international trade involves counterfeit（假冒的） goods, according to a 2013 United Nations report. These illicit products -- which include electronics, automotive and aircraft parts, pharmaceuticals, and food -- can pose...

14-04-09 Materials scientists have long known that introducing defects into three-dimensional materials can improve their mechanical and electronic properties. Now a new Northwestern study finds how defects affect two-dimensional crystalline（水晶般的） stru...

14-03-25 The experimental and numerical study of the behaviour of polymers in concentrated solutions is a line of research that is still highly active. In the past, it enabled us to understand why materials like rubber have certain elastic（弹性的） properti...

14-03-24 Inspired by natural materials such as bone -- a matrix of minerals and other substances, including living cells -- MIT engineers have coaxed（哄骗，劝诱） bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nan...

14-03-05 Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune t...
