The Shanghai-based synchrotron, which uses super-powerful X-rays to resolve the structure of matter down to the level of atoms, has detected evidence that acupuncture points differ from other parts of the body.
Researchers have shown that even nanoscale modulations of the surface geometry can significantly influence a ferroelectric film's response to an applied electric field, yielding valuable information for the efficient design of nanotechnological devices based on such materials.
An international team of researchers has identified a new theoretical approach that may one day make the synthesis of hydrogen fuel storage materials less complicated and improve the thermodynamics and reversibility of the system.
A group of Marshall University researchers and their colleagues in Japan are conducting research that may lead to new ways to move or position single molecules - a necessary step if man someday hopes to build molecular machines or other devices capable of working at very small scales.
Wie die renommierte Zeitschrift Nature Physics berichtet, ist es Wissenschaftlern der Universitaet Hamburg unter der Leitung von Prof. Roland Wiesendanger gelungen, die Richtungsabhaengigkeit der magnetischen Kopplung zwischen einzelnen Atomen auf Oberflaechen direkt zu vermessen.
Pin-sharp projections, light that's whiter than white, varnishes that make sounds if the temperature changes: at nano tech 2010 in Tokyo, Fraunhofer researchers present nanotechnology that is a veritable feast for the senses.
Neutron scattering experiments performed at the Department of Energy's Oak Ridge National Laboratory give strong evidence that, if superconductivity is related to a material's magnetic properties, the same mechanisms are behind both copper-based high-temperature superconductors and the newly discovered iron-based superconductors.
The fabrication of vertical silicon nanowire arrays has already been reported. Yet there needs to be a more thorough research into the electrical properties of silicon nanowires in order to be able to build reliable transistors for a new generation of microchips.
Scientists at the Department of Microsystems Engineering (IMTEK) and the Freiburg Materials Research Center (FMF) have succeeded in developing a method for treating the surface of nanoparticles which greatly improves the efficiency of organic solar cells. The researchers were able to attain an efficiency of 2 percent by using so-called quantum dots composed of cadmium selenide.
Considerable progresses made in controlling quantum gases open up a new avenue to study chemical processes. Researchers have now succeeded in directly observing chemical exchange processes in an ultracold sample of cesium atoms and Feshbach molecules.
