13-07-27 The mineral molybdenum disulfide (MoS2), which, when solid, behaves in many ways like grease（油脂） , has semiconducting properties that make it a promising alternative to silicon or graphene in electronic devices. It also strongly absorbs visible...

13-07-19 If you squeeze a normal object in all directions, it shrinks in all directions. But a few strange materials will actually grow in one dimension when compressed. A team of chemists has now discovered a structure that takes this property to a new leve...

13-06-02 All chefs know that you have to break some eggs to make an omelet（煎蛋卷） , and that includes engineers at Iowa State University who are using high-frequency sound waves to break down plant materials in order to cook up a better batch of biofuel....

13-05-17 With the Deepwater Horizon disaster emphasizing the need for better ways of cleaning up oil spills, scientists are reporting that unprocessed, raw cotton may be an ideal, ecologically friendly answer, with an amazing ability to sop up（吸水） oil. T...

13-04-17 Scientists at Lawrence Livermore National Laboratory (LLNL) and UC Berkeley and have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. Methane is a substantial（大量的） driver...

13-04-10 Inspired by a traditional Balkan bedbug remedy（补救，治疗） , researchers have documented how microscopic hairs on kidney bean leaves effectively stab and trap the biting insects, according to findings published online today in the Journal of the R...

13-01-14 The international community should cut its dependence on hazardous nuclear materials and eradicate nuclear terrorism with the aid of multilateral frameworks, Li Hong, secretary-general of the China Arms Control and Disarmament Association, said in a...

13-01-07 Technologically valuable ultrastable（超稳定的） glasses can be produced in days or hours with properties corresponding to those that have been aged for thousands of years, computational and laboratory studies have confirmed. Aging makes for higher...

12-12-29 Contributing geometric（几何学的） and topological（拓扑的） analyses of micro-materials, University of Massachusetts Amherst mathematician Robert Kusner aided experimental physicists at the University of Colorado (UC) by successfully explaining the...

12-12-24 In a forced game of molecular tug-of war, some strings of atoms can act like a lever（杠杆） , accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could use these molecular levers to drive chemical a...
