Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a method for coating metal surfaces with an ultrathin film containing nanoparticles which renders the metal resistant to corrosion and eliminates the use of toxic chromium for this purpose.
Flexible display screens and cheap solar cells can become a reality through research and development in organic electronics. Physicists at Umea University in Sweden have now developed a new and simple method for producing cheap electronic components.
A new book from the National Research Council finds serious weaknesses in the government's plan for research on the potential health and environmental risks posed by nanomaterials, which are increasingly being used in consumer goods and industry.
The safety of early applications of synthetic biology may be adequately addressed by the existing regulatory framework for biotechnology, especially in contained laboratories and manufacturing facilities. But further advances in this emerging field are likely to create significant challenges for U.S. government oversight.
Though a year has passed since the discovery of a new family of high-temperature superconductors, a viable explanation for the iron-based materials? unusual properties remains elusive. But a team of scientists working at the National Institute of Standards and Technology may be close to the answer.
Forget dancing angels, a research team has shown how to detect and monitor the tiny amount of light reflected directly off the needle point of an atomic force microscope probe, and in so doing has demonstrated a 100-fold improvement in the stability of the instrument?s measurements under ambient conditions.
If physicists lived in Flatland - the fictional two-dimensional world invented by Edwin Abbott in his 1884 novel - some of their quantum physics experiments would turn out differently (not just thinner) than those in our world. The distinction has taken another step from speculative fiction to real-world puzzle with a paper from the Joint Quantum Institute reporting on a Flatland arrangement of ultracold gas atoms.
Using two different types of chemical etching to create features at both the micron and nanometer size scales, researchers at the Georgia Institute of Technology have developed a surface treatment that boosts the light absorption of silicon photovoltaic cells in two complementary ways.
A team of scientists from Virginia Commonwealth University, the University of Uppsala in Sweden, and the Savannah River National Laboratory have identified that carbon nanostructures can be used as catalysts to store and release hydrogen, a finding that may point researchers toward developing the right material for hydrogen storage for use in cars.
The European Science Foundation has announced the conference Nanocarbons: from physicochemical and biological properties to biomedical and environmental effects, from September 8-13, 2009 in Acquafredda di Maratea, Italy.
