Einen Ueberblick ueber die aktuelle Literatur im Bereich der Nanotechnologie gibt der neue 'Sonderinformationsdienst Nanotechnologie', den die Fachbibliothek der Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin (BAuA) jetzt veroeffentlicht hat.
Structured surfaces have special properties. It would be desirable to make these properties switchable. This, for example, would allow for friction and adhesion to be specifically switched on and off on metallic surfaces. How to train structured surfaces for this effect has been under investigation by the junior research group 'Metallic Microstructures' at the Leibniz Institute for New Materials since January 2011.
On team of 9-14 year old kids participate in the First Lego League competition with research in the field of biomedical engineering on how to prevent stroke-causing blood clots in the brain using nanotechnology.
Scientists have created a diamond-like lattice composed of gold nanoparticles and viral particles, woven together and held in place by strands of DNA. The structure - a distinctive mix of hard, metallic nanoparticles and organic viral pieces known as capsids, linked by the very stuff of life, DNA - marks a remarkable step in scientists' ability to combine an assortment of materials to create infinitesimal devices.
Researchers from the Georgia Institute of Technology describe a new method of combining top-gate organic field-effect transistors with a bilayer gate insulator. This allows the transistor to perform with incredible stability while exhibiting good current performance. In addition, the transistor can be mass produced in a regular atmosphere and can be created using lower temperatures, making it compatible with the plastic devices it will power.
Nanosilber ist keine neue Erfindung der Nanotechnologien, sondern bereits seit mehr als 100 Jahren in verschiedenen Produkten im Einsatz. Dies zeigt eine neue Empa-Studie. Schon damals wurde die antimikrobielle Wirkung winziger Silberteilchen genutzt, die als 'kolloidales Silber' bekannt waren.
In future, Empa and the Cantonal Hospital St. Gall will work together more intensively in various fields of research and development in medicinal and medical materials. In addition to previous cooperative projects in the field of human stem cells, current research topics such as nano-safety, immunology and implant development will also be tackled.
A paper published in the January issue of the journal Nanomedicine could provide the foundation for a new ovarian cancer treatment option -- one that would use an outside-the-body filtration device to remove a large portion of the free-floating cancer cells that often create secondary tumors.
Researchers in Japan have developed a ternary material with a core-shell structure consisting of multi-walled carbon nanotubes, an ionic liquid, and a conducting polymer. It was found that, when used as the counter electrode of dye-sensitized solar cells, the material exhibits photoelectric conversion efficiency as high as that of platinum.
Scientists are reporting development of a new approach for dealing with offensive household and other odors - one that doesn't simply mask odors like today's room fresheners, but eliminates them at the source.
For the first time, scientists from both sides of the Atlantic are joining forces to discover what the risks of manufactured nanomaterials might be, and provide the scientific evidence base needed to inform government and industry policies.
