An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation’s civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters.
To move your arm or leg, certain muscles need to change shape, to either lengthen or contract. Now scientists have made liquid-crystalline particles that can change shape in a similar way, but which are only micrometers across. Professor Rudolf Zentel and his colleagues at the Universities of Mainz and Strasbourg have prepared these tiny shape-changing materials out of elasticized liquid crystals, taking advantage of a continuous fluidic device for fabrication.
Scientists drew fittingly from Roman mythology when they named a unique class of miniscule particles after the god Janus, who is usually depicted as having two faces looking in opposite directions.
For years, scientis...
Carbon Design Innovations, Inc. (C|D|I) today announced that it has grant in the amount of $390,000 from the National Institutes of Health (NIH) Small Business Innovation Research (SBIR) Program. The grant will fund the development and commercialization of Carbon Nanotube (CNT) Atomic Force Microscope (AFM) probes for bioimaging and investigations in cellular biology.
Researchers are developing a new class of tiny mechanical devices containing vibrating, hair-thin structures that could be used to filter electronic signals in cell phones and for other more exotic applications.
Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. A major problem, however, is that the m...
The Casimir force, also known as the Casimir effect, is typified by the small attractive force that acts between two close parallel uncharged conducting plates. Today, this force has become an interdisciplinary subject of study, playing an important role in condensed matter physics, quantum field theory, atomic and molecular physics, gravitation and cosmology, and mathematical physics.
EnerG2, a Seattle based company focused on introducing advanced nano-structured materials for next- generation energy storage breakthroughs, today announced that the United States Department of Energy has awarded the com...
U.S Department of Energy Secretary Steven Chu announced today that more than $327 million in new funding from the American Recovery and Reinvestment Act will go toward scientific research, instrumentation, and laboratory...
A new study raises the possibility that flies and other insects that encounter nanomaterial "hot spots," or spills, near manufacturing facilities in the future could pick up and transport nanoparticles on their bodies, transferring the particles to other flies or habitats in the environment.
