Towards a European Observatory on Nanotechnologies

Establishing a permanent European Observatory on Nanotechnologies is one of the goals of the EU-funded observatoryNANO project, which started recently. Based on the methodologies developed and validated during the project and in the framework of similar initiatives, the observatory will in the future provide ongoing and independent support to decision-makers, the project partners hope.

Nanochemistry inside carbon nanotubes

(Nanowerk Spotlight) As far as test tubes go, it doesn't get any smaller than a single-walled carbon nanotube (SWCNT). Among the wide range of interesting properties exhibited by SWCNTs is their capacity to encapsulate molecules within their quasi one-dimensional cavity. The confinement offered by the nanotube could serve as a nanoscale test tube to constrain a chemical reaction. This was demonstrated in principle back in 1998, when the coalescence of adjacent fullerenes was observed by transmission electron microscopy ("Encapsulated C60 in carbon nanotubes"). In the following years, scientists have extensively experimented with filling nanotubes with other fullerenes, atoms, molecules and, very recently, with organic molecules. Owing to their large variety with diverse chemical properties, the incorporated organic molecules can tune the

"Parametron" comes back to life

Researchers in Japan have taken the first step towards making a nanomechanical computer. Imran Mahboob and Hiroshi Yamaguchi at NTT Basic Research Labs in Kanagawa have proposed a way to perform logic operations using nanomechanical systems (NEMS). The concept is based on the Parametron â€“ a logic processing system developed in Japan more than 50 years ago.

Made-to-order Isotopes Hold Promise On Science's Frontier

Designer labels have a lot of cachet â€“ a principle thatâ€™s equally true in fashion and physics. The future of nuclear physics is in designer isotopes â€“ the relatively new power scientists have to make specific rare isotopes to solve scientific problems and open doors to new technologies, according to Bradley Sherrill, a University Distinguished Professor of physics and associate director for research at the National Superconducting Cyclotron Laboratory at Michigan State University.
