Das BfR hatte zu einem Workshop ueber Nanopartikel in Verbraucherprodukten eingeladen, um bestehende Risiken und moegliche Handlungsoptionen fuer einen umfassenden Schutz der Verbraucherinnen und Verbraucher zu diskutieren.
Researchers have developed a manufacturing process for nanocellulose powder, the raw material for creating polymer composites which can be used, for example, in lightweight structures for the car industry or as membrane and filter material for biomedicinal applications.
If quantum computers are ever to be realized, they likely will be made of different types of parts that will need to share information with one another, just like the memory and logic circuits in today's computers do. However, prospects for achieving this kind of communication seemed distant - until now. A team of physicists has shown for the first time how these parts might communicate effectively.
Recent work offers a way to measure accurately both the distribution of cluster sizes in a sample and the characteristic light absorption for each size. The latter is important for the application of nanoparticles in biosensors.
New research by engineers at the Yale School of Engineering and Applied Science demonstrates that nanomechanical resonators can operate at much higher amplitudes than previously thought. The results represent an advance in optomechanics, in which the force of light is used to control mechanical devices. The findings could have implications for future communications and sensing technologies.
When combined with biological molecules, such as antibodies, carbon nanotubes have the potential to perform a range of new and useful functions in miniature biotechnology devices - from detecting breast cancer cells to the Penn-Alabama State team's salmonella project.
About every three days, Colleen Alexander, a chemistry graduate student, feeds cells that cause a deadly type of brain cancer. It's a ritual that involves assessing the health of the cells under a microscope, washing away dead cells with a special solution and instilling clean medium that will nurture the living cells and generate new ones. At some point, these cells will be subjected to chemotherapy agents attached to nanoparticles made of gold.
From January 1, 2012 ThyssenKrupp Steel Europe AG will be funding a group of young researchers from Ruhr University Bochum. The computer scientists and mathematicians will carry out research jointly with the Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) over a period of six years.
The 2012 Symposia on VLSI Technology and Circuits, to be held at the Hilton Hawaiian Village in Honolulu, HI, June 12-14, 2012 (Technology) and June 13-15, 2012 (Circuits), announce their respective Calls for Papers.
