Exploring the market for 3-D nanopatterning techniques

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.

Materialforschung in neuer Dimension

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.

Liquid crystal droplets discovered to be exquisitely sensitive to an important bacterial lipid

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.

Record efficiency of 18.7% for flexible CIGS solar cells on plastics

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.

Experiments settle long-standing debate about mysterious array formations in nanofilms

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.

Nanotechnology patch for the heart restores damaged areas

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.
