• 巴克球变为巴克弹

    15-03-20 In 1996, a trio of scientists won the Nobel Prize for Chemistry for their discovery of Buckminsterfullerene -- soccer-ball-shaped spheres of 60 joined carbon atoms that exhibit special physical properties. Now, 20 years later, scientists have figure...

  • 量子技术挑战简单的解决办法

    14-10-30 A solution to one of the key challenges in the development of quantum technologies has been proposed by University of Sussex physicists. In a paper published today (28 October) in Nature Communications, Professor Barry Garraway and colleagues show h...

  • 锂离子电池工作时的内部情况

    14-09-10 For the first time, researchers have been able to open a kind of window into the inner workings of a lithium-ion battery. Using a neutron beam, chemists and engineers at The Ohio State University were able to track the flow of lithium atoms into and...

  • 压力之下的玻璃内部结构变化

    14-09-02 Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structur...

  • 控制金属晶体生长的方法

    14-05-28 Researchers have announced the first ever method for controlling the growth of metal-crystals from single atoms. Published in the journal Nature Communications and developed at the University of Warwick, the method, called Nanocrystallometry, allows...

  • 对铜原子的压力测试

    13-10-23 Scientists used the powerful X-ray laser at the U.S. Department of Energy's SLAC National Accelerator Laboratory to create movies detailing trillionths-of-a-second changes in the arrangement of copper atoms after an extreme shock. Movies like these...

  • 美国大峡谷已存在七千万年

    12-12-03 An analysis of mineral grains from the bottom of the western Grand Canyon indicates it was largely carved out by about 70 million years ago -- a time when dinosaurs were around and may have even peeked over the rim, says a study led by the Universit...

  • 纳米粒子与人造原子

    12-05-31 In the growth of crystals, do nanoparticles act as artificial atoms forming molecular-type building blocks that can assemble into complex structures? This is the contention(争论) of a major but controversial theory to explain nanocrystal growth. A...

  • 欧洲核能研究所捕获到反物质原子

    10-11-19 Geneva, 17 November 2011. The ALPHA experiment at CERN has taken an important step forward in developing techniques to understand one of the Universe's open questions: is there a difference between matter and antimatter? In a paper published in Natu...

  • 冷原子与纳米碳管可聚集构成原子级“黑洞”

    10-04-07 Carbon nanotubes(碳纳米管) , long touted(被吹捧的) for applications in materials and electronics, may also be the stuff of atomic-scale black holes. Physicists at Harvard University have found that a high-voltage nanotube can cause cold atoms to...
