Scientists at Argonne National Laboratory's CNM Nanophotonics Group have measured how light emission from individual colloidal semiconductor nanocrystals, or quantum dots, is modified when in proximity to smooth metal films.
Four of R&D Magazine's prestigious R&D 100 Awards for 2009, which recognize the 100 most significant proven technological advances of the year, have gone to researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and their colleagues.
At the EuroNanoMedicine 2009 conference, leading experts from various disciplines such as medicine, nanotechnology, chemistry, cell biology and toxicology will present and discuss recent progress and results. The conference will take place on September 28-30, 2009 in Bled, Slovenia.
Even Albert Einstein might have been impressed. His theory of general relativity, which describes how the gravity of a massive object, such as a star, can curve space and time, has been successfully used to predict such astronomical observations as the bending of starlight by the sun, small shifts in the orbit of the planet Mercury and the phenomenon known as gravitational lensing. Now, however, it may soon be possible to study the effects of general relativity in bench-top laboratory experiments.
Physicists at New York University have developed a technique to record three-dimensional movies of microscopic systems, such as biological molecules, through holographic video. The work has potential to improve medical diagnostics and drug discovery.
Two international coalitions of NGOs, the European Environmental Bureau and the International POPs Elimination Network (IPEN) Nanotechnology Working Group, have challenged industry claims about the potential environmental benefits provided by nanotechnology products.
Elsevier today announces the 'Article of the Future' project, an ongoing collaboration with the scientific community to redefine how a scientific article is presented online. The project takes full advantage of online capabilities, allowing readers individualized entry points and routes through content, while exploiting the latest advances in visualization techniques.
In future therapies, synthetic nanoparticles may well be able to ferry medicines and even genes to targets inside the body. These nanovehicles can now be directly tested and optimized using a highly sensitive microscopic method that can trace single particles all the way into a cell.
Unterschiede im Bereich von einigen tausendstel Mikrometern bei einer Oberflaechenbeschichtung koennen darueber entscheiden, ob Implantate sich ihrer organischen Umgebung mehr oder weniger gut anpassen.
Newly announced National Institutes of Health (NIH) funding will expand the reach of ongoing University of Alabama at Birmingham research into a unique nanostructured coating to improve the performance and longevity of total joint replacement components.
