13-09-22 carbon nanotubes' outstanding mechanical, electrical and thermal properties make them an alluring（诱惑的） material to electronics manufacturers. however, until recently scientists believed that growing the high density of tiny graphene cylinders n...

13-08-07 a team of researchers led by north carolina state university has developed a technique that provides real-time images of how magnesium（镁） changes at the atomic scale when exposed to radiation. the technique may give researchers new insights into...

13-08-01 ethanol（乙醇） from corn and other plants could become the sustainable, raw material for a huge variety of products, from plastic packaging to detergents（洗涤剂） to synthetic rubber, that are currently petroleum-based. this was the conclusion of...

13-07-10 the unique properties of graphene（石墨烯） such as its incredible strength and, at the same time, its little weight have raised high expectations in modern material science. graphene, a two-dimensional crystal of carbon atoms packed in a honeycomb...

13-06-27 most efforts at improving solar cells have focused on increasing the efficiency of their energy conversion, or on lowering the cost of manufacturing. but now mit researchers are opening another avenue for improvement, aiming to produce the thinnest...

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...

13-05-19 physicists may have created the smallest drops of liquid ever made in the lab. that possibility has been raised by the results of a recent experiment conducted by vanderbilt physicist julia velkovska and her colleagues at the large hadron collider,...

13-04-10 a team of researchers has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures. for the first time, they developed a way to get around the severe distortions of high-energy x-ray beams that are used to...

13-03-15 fashion and physiology please, sir, i guess you'd better step up right away, or it will be too late, for i heard miss rose say she knew you wouldn't like it, and she'd never dare to let you see her. phebe said this as she popped her head into the st...
