How do you handle the tiny components needed for constructing nanoscale devices? A European consortium has built two micro-robotic demonstrators that can automatically pick up and install carbon nanotubes thousands of times thinner than a human hair.Carbon nanotubes, rolled up sheets of carbon only a few tens of nanometers in diameter, could become an essential part of the nanotechnologist's construction kit. But there is a problem: how can you handle objects which are so thin that they...

Massachusetts Institute of Technology researchers say they have created carbon nanotubes without using a metal catalyst. The scientists said their finding that oxides, as well as metals, can grow carbon nanotubes changes science's understanding of nanotube growth. Carbon nanotubes -- tiny tubes of graphite -- promise to add speed to electronic circuits and strength to materials such as carbon composites that are used in airplanes and race cars. But the MIT scientists said a major problem has...

 Carbon nanotubes "” tiny, rolled-up tubes of graphite "” promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. A major problem, however, is that the metals used to grow nanotubes react unfavorably with materials found in circuits and composites. But now, researchers at MIT have for the first time shown that nanotubes can grow without a metal catalyst. The researchers demonstrate that zirconium oxide, the...

Rice scientists use nanomaterials to grow flying carpets, 'odako' kitesWith products that range from carpets to kites, you'd think Rice University chemist Bob Hauge was running a department store. What he's really running is a revolution in the world of carbon nanotechnology. In a paper published this month in Nano Research, Hauge's Rice University team describes a method for making "odako," bundles of single-walled carbon nanotubes (SWNT) named for the traditional Japanese kites...

New video showing the atom-by-atom growth of carbon nanotubes reveals they rotate as they grow, much like the halting motion of a mechanical clock's second hand. FEM video from Universit© Lyon1/CNRS shows the rotation of the nanotube during growth. The observation helps confirm a new rotational theory of carbon nanotube growth offered by Rice researchers in February.Published online this month by researchers at France's Universit© Lyon1/CNRS and Houston's Rice University, the...

Physics professor at UH uses Air Force grants to create highly conductive nanocompositesIf one University of Houston professor has his way, the inexpensive plastic now used to manufacture CDs and DVDs will one day soon be put to use in improving the integrity of electronics in aircraft, computers and iPhones.Thanks to a pair of grants from the U.S. Air Force, Shay Curran, associate professor of physics at UH, and his research team have demonstrated ultra-high electrical conductive properties...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
