Researchers have reported on the first combined quasi-hydrostatic, high-pressure, small-angle x-ray scattering (SAXS) and micro x-ray diffraction (XRD) studies on individual faceted, 3-D supercrystals self-assembled from colloidal 7.0-nm PbS nanocrystals.
More than 50 years after the invention of the laser, scientists at Yale University have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.
The U.S. Environmental Protection Agency (EPA) has awarded $5.5 million to three consortia to support innovative research on nanotechnology. EPA, in collaboration with the United Kingdom's Natural Environment Research Council, are leading this scientific research effort to better understand the potential risks to people's heath and the environment. The scientific information developed from the research can help guide EPA and other agencies in decisions about the safety of new materials and products that are made using nanotechnology.
A corrective strategy used by astronomers to sharpen images of celestial bodies can now help scientists see with more depth and clarity into the living brain of a mouse. Eric Betzig, a group leader at the Howard Hughes Medical Institute's Janelia Farm Research Campus, will present his team's latest work using adaptive optics for biology at the annual meeting of the American Association for the Advancement of Science in Washington, D.C.
Building on its past nanotechnology work, the International Food Policy Research Institute (IFPRI) recently released the discussion paper "Agricultural, food, and water nanotechnologies for the poor: Opportunities, constraints, and role of the Consultative Group on International Agricultural Research".
Working on a science fair project with his lab partner Nikki, Harold Biggums finds himself transformed into a tiny superhero and flung into the midst of an alien plot to take over the world - a plot that he and Nikki can foil only by defying gravity, walking on water and charging across electric fields.
The International Conference on Frontiers of Characterization and Metrology for Nanoelectronics 2011 (IC-FCMN 2011) will be May 23-26 at MINATEC, an international center for micro- and nanotechnologies, in Grenoble, France.
The National Nanotechnology Coordination Office (NNCO) will hold a workshop on March 10-11, 2011, to provide an open forum and engage in an active scientific discussion about environmental health and safety questions for nanomaterials and nanotechnology-enabled products, to encourage joint US-EU programs of work that would leverage resources, and to establish communities of research practice, including identification of key points of contact/interest groups/themes between key US and EU researchers for near-term and future collaborations.
Einmal einen direkten Blick auf die Strukturen eines modernen Mikrochips werfen, die bis zu 32 nm klein und damit mit dem blossen Auge nicht sichtbar sind - eine faszinierende Idee! Mit einem extra fuer Lehr-Zwecke entwickelten Rasterkraftmikroskop koennen Berufs- und andere Schulen ihre Schueler diesem Ziel etwas naeher bringen und sie fit machen fuer eine der ganz aktuellen Anforderungen der High-Tech-Welt, naemlich die Erforschung der Mikro- und Nanowelt.
Researchers at MIT and Northeastern have come up with a new system for monitoring biomedical indicators - such as levels of sodium or glucose in the blood - that could someday lead to implantable devices that would allow, for example, people with diabetes to check their blood sugar just by glancing at an area of skin.
Twenty-eleven is the year that regulation of nanotechnology will move from a hypothetical possibility to a real issue for companies in virtually every industry sector that are benefitting from the new science of nanotechnology. Such regulation will raise profound policy, business and legal issues, which will be examined at a conference on March 21 sponsored by the Sandra Day O'Connor College of Law at Arizona State University.
A Colorado State University professor has successfully turned a mineral compound into a material that can pass current through a nanoparticle network - an important discovery into more efficient, inexpensive solar cell materials.
