Cuts in federal funding of nanotechnology research threaten to slow progress toward some of the field's greatest promises, including commercialization of sustainable new energy sources that do not contribute to global warming.
To the lengthy list of serendipitous discoveries – gravity, penicillin, the New World – add this: Scientists have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment.
While a movie about giant robots that undergo structural transformations is breaking box office records this summer, a scientific study about structural transformations within single nanocrystals is breaking new ground for the design of novel materials that will serve next-generation energy storage batteries and solar energy harvesting devices.
Observation of a scientific rule being broken can sometimes lead to new knowledge and important applications.
The world's first three-dimensional plasmon rulers, capable of measuring nanometer-scale spatial changes in macrmolecular systems, have been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with researchers at the University of Stuttgart, Germany.
Composites are combinations of materials that produce properties inaccessible in any one material.
In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory (Berkeley Lab) have reported a technique by which the electrical conductivity of nanorod crystals of the semiconductor cadmium-selenide was increased 100,000 times.
Availability of solar cell materials could limit large-scale deployment of photovoltaics.
