Rice University's Nobel Prize-winning researchers dreamed of solving the world's problems, but that can only happen if new generations learn to carry on their work. That's a prime reason the tier-one university is celebrating the Year of Nano in 2010, the 25th anniversary of the discovery of the carbon 60 molecule - aka the buckminsterfullerene, or buckyball.
Positronium is a short-lived system in which an electron and its anti-particle are bound together. In 2007, physicists at the University of California, Riverside created molecular positronium, a brand-new substance, in the laboratory. Now they have succeeded in isolating for the first time a sample of spin polarized positronium atoms.
Registration opens today (May 1) for the Bristol Nanoscience Symposium 2010, a two-day event that will bring together leading figures from the international scientific community at one of the finest nanoscience facilities in the world.
Modern glass facades inform the architecture of major cities throughout the world. In recent years, however, there have been cases of broken glass, with collapsing facades endangering passers-by. Now, a special sensor can detect micro-fissures and warn of impending breakage beforehand.
A new nanocoating ensures a perfectly non-reflecting view on displays and through eyeglasses. The necessary surface structure is applied to the polymeric parts during manufacture, obviating the need for a separate process step. The hybrid coating has further advantages: the components are scratch-proof and easy to clean.
Is smell a personal sense, one that is specific to culture? No, says an Israeli team of scientists who have successfully 'trained' an electronic system capable of predicting the pleasantness of new odours.
A team of scientists at UC Santa Barbara that helped pioneer research into the quantum properties of a small defect found in diamonds has now used cutting-edge computational techniques to produce a road map for studying defects in alternative materials.
Scientists have discovered how cells ensure the correct distribution of proteins throughout their interior. What they have found is that many of the proteins which need to be transported to the cell membrane are furnished with a kind of anchor consisting of a fatty acid, which serves to embed the proteins in the cell membrane.
Hydrogen would command a key role in future renewable energy technologies, experts agree, if a relatively cheap, efficient and carbon-neutral means of producing it can be developed. An important step towards this elusive goal has been taken by a team of researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley.
'Children are not small adults' - pediatricians say that's what makes their specialty different from the practice of medicine in adults. For similar reasons, researchers exploring the medical uses of nanotechnology believe that the use of molecular-level nanomedicine techniques in children will also require its own specialty.
Scientists have succeeded for the first time in making, out of DNA double stands, an interlocked molecule (rotaxane) with freely moveable components. This opens up exciting possibilities for nanorobotics and synthetic biology.
The application of nanotechnology will have a major influence in many fields of medicine. Novel nano-based materials appear in drug delivery systems, diagnostics, imaging, biosensing, and medical materials and devices.
