After announcing last April a method for growing exceptionally long, straight, numerous and well-aligned carbon cylinders only a few atoms thick, a Duke University-led team of chemists has now modified that process to create exclusively semiconducting versions of these single-walled carbon nanotubes.
The smallest mechanical switch plus an electronic switch of a type never seen before. That's how physicist Marius Trouwborst sums up the results of his PhD research on electric current through atoms and molecules.
Elsevier today announced the launch of SciTopics, a free online expert-generated knowledge sharing service for the research community to quickly offer scientific, technical and medical knowledge on a variety of subjects.
The Josephson effect is the phenomenon of current flow across two weakly coupled superconductors, separated by a very thin insulating barrier. It has important applications in quantum-mechanical circuits, such as superconducting quantum interference devices.
Jordi Pascual, Director del Institut Catala de Nanotecnologia, y Nicolas Garcia, Director del laboratorio de Fisica de Sistemas pequenos y Nanotecnologia, nos acompanan en el plato para ver las posibilidades de esta ciencia tan prometedora.
A range of complex surgical operations necessary to treat stroke victims, confront hardened arteries or address blockages in the bloodstream are about to be made safer as researchers from the Micro/Nanophysics Research Laboratory at Australia?s Monash University put the final touches to the design of micro-motors small enough to be injected into the human bloodstream.
SEMI Europe confirmed that Anatoly Chubais, head of Russian Corporation of Nanotechnologies (RUSNANO) will join the roster of keynote speakers at this year's Industry Strategy Symposium (ISS Europe), February 1-3, 2009, Dresden, Germany.
The creation of a reproducible crystallisation process is a fundamental challenge to drug manufacturers, but a technique which provides real time detailed analyses of chemical processes could provide an answer.
Electronic systems designed to perform simple functions, such as monitor the temperature on a yogurt pot, mustn't cost much: This is where printed electronics are at an advantage. Researchers are now significantly improving the properties of printed circuits.
Exposing silicon wafers to light during chip manufacture requires special fixtures called chucks. Novel electrostatic chucks made of glass ceramics are incredibly flat. This prevents structural distortions on the exposure mask and the silicon chip.
Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. Now, University of Florida engineering researchers have tapped the working parts of cells to clear a major hurdle to creating such 'smart dust'.
