Researchers have devised a new scheme for preparation of core-shell nanocrystals, by combining the microemulsion and ultrasonication methods, which features moderate synthesis conditions and does not require any surfactants.
The expert meeting on Inhalation Toxicity Testing for Nanomaterials was held on 19-20 October 2011 in The Hague, hosted by the Netherlands, with the aim of discussing the results of the OECD Sponsorship Programme on this specific topic and addressing issues relevant to inhalation toxicity.
The Environmental Unit of the Tecnalia Technology Corporation, the Basque Foundation for Health Innovation and Research (BIOEF) and Fluytec, a company specialising in filtration solutions, have developed a filtration system capable of retaining 95% of nanoparticles thanks to the results of the SIFINA project.
Researchers from Karlsruhe, Strasbourg, and Japan have now developed a magnetic memory with one bit per molecule. By an electric pulse, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state.
Using the compound eyes of the humble moth as their inspiration, an international team of physicists has developed new nanoscale materials that could someday reduce the radiation dosages received by patients getting X-rayed, while improving the resolution of the resulting images.
