Researchers demonstrate technique for growing virtually pure samples of single-wall carbon nanotubes
Researchers from the University of Southern California and the National Institute of Standards and Technology have demonstrated a technique for growing virtually pure samples of single-wall carbon nanotubes with identical structures, a process they liken to "cloning" the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes of a specific structure to order.

One of the key challenges has been the reliability of the nanometer-scale tips, especially with performing nano-writing on hard, semiconductor surfaces. Now, researchers at the University of Illinois, University of Pennsylvania, and Advanced Diamond Technologies Inc., have created a new type of nano-tip for thermal processing, which is made entirely out of diamond.

Partners from all over Europe will investigate the European labour market for personnel trained in nanotechnology. The relevance of existing nanotechnology education and training in universities, vocational training institutes and secondary schools for the needs of industrial and other employers will also be explored. By 2015, a model curriculum will be made available online.

Using DESY's X-ray laser FLASH, a team of scientists from Hamburg has traced the ultrafast explosion of iodine molecules. The group used the X-ray laser as a kind of high-speed camera - the observed molecular explosion took place within a millionth of a billionth of a second (i.e. within femtoseconds).

Read moreNanoparticles: a greater danger to the environment than previously thought
Researchers found that the offspring of water fleas (Daphnia magna) exposed to nanoparticles of titanium dioxide react significantly more sensitively than the offspring of parents from a control group. This is the case even though the offspring themselves are not exposed to the nanoparticles.

Read moreNew metamaterial lens focuses radio waves
Researchers at MIT have fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. The concave lens exhibits a property called negative refraction, bending electromagnetic waves - in this case, radio waves - in exactly the opposite sense from which a normal concave lens would work.

Drawing heavily upon nature for inspiration, a team of researchers has created a new artificial lens that is nearly identical to the natural lens of the human eye. This innovative lens, which is made up of thousands of nanoscale polymer layers, may one day provide a more natural performance in implantable lenses to replace damaged or diseased human eye lenses, as well as consumer vision products; it also may lead to superior ground and aerial surveillance technology.

We can look through glass, but what glass itself looks like on the inside has so far remained a mystery - at least as far as the precise position of the atoms is concerned. Scientists at the Fritz-Haber-Institute of the Max Planck Society in Berlin are now the first to have imaged the network of silicon and oxygen atoms - the main components of glass - in a silica film.
