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.
The development of a new generation of actuators has undergone tremendous progress. Cheaper piezo actuators resisting humidity, having fewer cracks and an extended lifetime may well become reality thanks to a close cooperation across borders between researchers, manufacturers and end-users.
Could humans one day walk on walls, like Spider-Man? A palm-sized device invented at Cornell that uses water surface tension as an adhesive bond just might make it possible. The rapid adhesion mechanism could lead to such applications as shoes or gloves that stick and unstick to walls, or Post-it-like notes that can bear loads.
Based on its recent research on the wearable energy harvesters market, Frost and Sullivan presents Holst Centre and imec with the 2009 European Frost and Sullivan Award for Technology Innovation for its wearable electrocardiograph energy harvesting solution, which provides tens of microwatts of energy per square centimetre for modules with 3x4 cm2 dimensions.
A community workshop sponsored by Society of Nuclear Medicine's Clinical Trials Network officially kicked off today, Feb. 1, in Albuquerque, N.M., and presented participants with a well-rounded series of educational sessions on the use of molecular imaging in clinical trials for investigational therapeutic drugs.
Northwestern University researchers are the first to design a bioactive nanomaterial that promotes the growth of new cartilage in vivo and without the use of expensive growth factors. Minimally invasive, the therapy activates the bone marrow stem cells and produces natural cartilage. No conventional therapy can do this.
