12-10-30 silicon is the workhorse of the electronics industry, serving as the base material for the tiny transistors that make it possible for digital clocks to tick and computers to calculate. now scientists have succeeded in creating near-atomically flat s...

12-10-24 much has been made of graphene's exceptional qualities, from its ability to conduct heat and electricity better than any other material to its unparalleled（无比的） strength: worked into a composite material, graphene can repel bullets better than...

12-10-18 living standards have soared during the twentieth century, and economists expect them to continue rising in the decades ahead. does that mean that we humans can look forward to increasing happiness? not necessarily, warns richard a. easterlin, an ec...

12-08-27 applied physicists at the harvard school of engineering and applied sciences (seas) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. at a mere 60 nanometers thick, the flat lens is ess...

12-08-20 a team of researchers at riken and the university of tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission. the surprise is that their methodology for solving this classic energy problem is based upon...

12-07-18 a network of p orous（多孔渗水的） carbon tubes that is three-dimensionally interwoven（互相编织） at nano and micro level -- this is the lightest material in the world. it weights only 0.2 milligrams per cubic centimetre, and is therefore 75 times...

12-06-18 scientists have managed to switch on and off the magnetism of a new material using quantum mechanics, making the material a test bed for future quantum devices. the international team of researchers led from the laboratory for quantum magnetism (lqm...

12-04-20 a team of researchers from taiwan and the university of california, berkeley, has harnessed nanodots to create a new electronic memory technology that can write and erase data 10-100 times faster than today's mainstream charge-storage memory product...

12-04-10 a north carolina state university researcher has developed a more efficient, less expensive way of cooling electronic devices -- particularly devices that generate a lot of heat, such as lasers and power devices. the technique uses a heat spreader m...

12-03-23 universitat autonoma de barcelona researchers, in collaboration with an experimental group from the academy of sciences of slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. the device was built using...
