3-dimensional surfaces with features below 100 nanometres have numerous applications ranging from optics to life sciences. The development of new manufacturing processes, based on nanoimprinting techniques (NIL), is a core aspect for the success of these applications.
Auf der Suche nach Materialien etwa fuer elektronische Bauteile koennen Physiker kuenftig einer neuen Spur folgen: Ein internationales Forscherteam hat zum ersten Mal praezise beobachtet, wie sich die physikalischen Eigenschaften einer Substanz - genauer gesagt des Metalloxids Lanthannickeloxid - aendern, wenn es in zweidimensionaler statt dreidimensionaler Form verarbeitet wird.
NVIDIA and the CGSociety, a division of Ballistic Media, have announced 'NVArt 6: Moving Innovation', a new worldwide digital art contest for artists to explore the future of electronic device design, with over $34,000 in prizes.
In the computer displays of medical equipment in hospitals and clinics, liquid crystal technologies have already found a major role. But a discovery reported from the University of Wisconsin-Madison suggests that micrometer-sized droplets of liquid crystal, which have been found to change their ordering and optical appearance in response to the presence of very low concentrations of a particular bacterial lipid, might find new uses in a range of biological contexts.
Scientists from NPL, in collaboration with Linkoping University, Sweden, have shown that regions of graphene of different thickness can be easily identified in ambient conditions using Electrostatic Force Microscopy (EFM).
Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have further boosted the energy conversion efficiency of flexible solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7% - a significant improvement over the previous record of 17.6% achieved by the same team in June 2010.
Scientists at the California Institute of Technology (Caltech) have conducted experiments confirming which of three possible mechanisms is responsible for the spontaneous formation of three-dimensional pillar arrays in nanofilms. These protrusions appear suddenly when the surface of a molten nanofilm is exposed to an extreme temperature gradient and self-organize into hexagonal, lamellar, square, or spiral patterns.
Scientists built a scaffold-looking structure consisting of carbon nanofibers and a government-approved polymer. Tests showed the synthetic nanopatch regenerated natural heart tissue cells - called cardiomyocytes - as well as neurons. In short, the tests showed that a dead region of the heart can be brought back to life.
