UCLA researchers, working in collaboration with colleagues at the University of Washington and Pennsylvania State University have used surface photochemical reactions to probe the critical role of substrate morphology on self-assembly and ligand environment, determining that molecules on curved surfaces have a greater range of orientations and, as a result, react more slowly than do molecules on flat surfaces.
In the last five years, next-??generation gene sequencing has brought down the cost of unlocking a single genome from $10 million to $10,000. While the savings is unprecedented, more can still be done to reduce the cost even further, an effort that would enable a host of applications in medical research and healthcare.
A team of KIT researchers directed by Professor Christian Koos has succeeded in developing a novel optical connection between semiconductor chips. 'Photonic wire bonding' reaches data transmission rates in the range of several terabits per second and is suited perfectly for production on the industrial scale.
Scientists at the University of Twente's MESA+ Institute for Nanotechnology have developed a new material that is not only extremely water-repellent but also extremely oil-repellent. It contains minuscule pillars which retain droplets. What makes the material unique is that the droplets stay on top even when they evaporate (slowly getting smaller).
Could our waste be part of the answer to humanity's energy problems? Some researchers think so, thanks to bacteria that chow down on everything from sewage to heavy metals and give off electricity as one of their own waste products.
Hydrogen is the ideal fuel for new types of fuel cell vehicles, but one problem is how to store hydrogen. In his doctoral dissertation Serhiy Luzan studies new types of materials for hydrogen storage. He also shows that new materials with interesting properties can be synthesized by the reaction of hydrogen with carbon nano-structured materials.
The Chinese government has launched a ten-year campaign to cultivate more than 10,000 talented individuals in scientific and technological fields in its latest effort to consolidate a foundation for the country's development.
Eine neue Methode lässt Germanium- Atome ohne Katalysator zu gleichmäßigen Drähten auf Silizium-Oberflächen zusammenwachsen. Dadurch können Kontaminationen ausgeschlossen und die Nanodrähte besser in Mikrochips integriert werden.
Scientists used their amped-up electron paramagnetic resonance (EPR) spectrometer to study the electron spin of free radicals and nitrogen atoms trapped inside a diamond. The improvement will pull back the veil that shrouds the molecular world, allowing scientists to study tiny molecules at a high resolution.
Nanoparticles have shown great promise in the targeted delivery of drugs to cells, but researchers at the University of Georgia have refined the drug delivery process further by using nanoparticles to deliver drugs to a specific organelle within cells.
Scientists are reporting development of a revolutionary new lens - flat, distortion-free, so small that more than 1,500 would fit across the width of a human hair - capable in the future of replacing lenses in applications ranging from cell phones to cameras to fiber-optic communication systems.
