    13-07-30 Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. As such, it is naturally exposed to the entire range of pressures and temperatures available in the whole...

  • 液态金属的3D结构模型

    13-07-10 Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature. It's difficult to create structures out of liquid...

  • 液态水泥变为液态金属的秘方

    13-05-28 In a move that would make the Alchemists of King Arthur's time green with envy, scientists have unraveled the formula for turning liquid cement into liquid metal. This makes cement a semi-conductor and opens up its use in the profitable consumer ele...

  • 铁铂合金可能成新一代硬盘存储材料

    13-05-21 Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron and platinum with an orde...

  • 花朵中的金属元素可能导致大黄蜂数量减少

    13-04-03 Beekeepers and researchers nationally are reporting growing evidence that a powerful new class of pesticides may be killing off bumblebees. Now, research at the University of Pittsburgh points toward another potential cause: metal pollution from alu...

  • 利用液态金属制造自愈性可伸展线材

    13-01-24 Researchers from North Carolina State University have developed elastic(有弹性的) , self-healing wires in which both the liquid-metal core and the polymer sheath(鞘,世界杯开户:护套) reconnect at the molecular level after being severed. Because we're using...

  • 水蒸汽与热量传递

    13-01-05 Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination(脱盐) plants, it yields a supply of clean water. The efficiency of su...

  • 金属氧化物能用于获取能源

    12-04-20 Harnessing the energy of sunlight can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice 'sandwich,' says a Binghamton University researcher in a new stud...

  • 研究人员发明危险重金属快速检测芯片

    11-08-02 UC researchers have developed the first lab-on-a-chip sensor to provide fast feedback regarding levels of the heavy metal manganese in humans. The sensor is both environmentally and child friendly, and will first be field tested in Marietta, Ohio, w...

  • 微金属粒子可影响改变DNA

    09-11-09 Tiny metal particles have been shown to cause changes to DNA across a cellular barrier - without having to cross it. 微小的金属粒子可以隔着细胞屏障改变DNA,而不必穿过它。 The study used fibroblast cells to illuminate the cell signalling The nanometr...
