Neuartiger Mechanismus zur Erzeugung und Nutzung von Spinstroemen

Forscher haben gezeigt, dass Spinstroeme mit Schallwellen erzeugt werden koennen. Weiterhin fanden sie, dass Spinstroeme auf isolierenden nichtmagnetischen Substraten auch durch einen weiteren Effekt, den sogenannten langreichweitigen Spin-Seebeck-Effekt erzeugt werden koennen.

Nanowires get into the groove

Researchers have found a way to grow semiconductor nanowires out, not up, on a surface, providing, for the first time, the much-needed guidance to produce relatively long, orderly, aligned structures.

Nanoscientists invent better etching technique

Imagine yourself nano-sized, standing on the edge of a soon-to-be computer chip. Down shoots a beam of electrons, carving precise topography that is then etched the depth of the Grand Canyon into the chip. From the perspective of scientists at the U.S. Department of Energy's Argonne National Laboratory, this improved form of etching could open the door to new technologies.

Nanotechnology researchers develop color-changing stress sensor

It is helpful - even life-saving - to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that's easy to read is a challenge. Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change.

Complex oxide interfaces are more complex than previously thought

Using experimental resources at EMSL, scientists from the Pacific Northwest National Laboratory and University College London have shown that intermixing occurs at the interface of two perovskites - lanthanum aluminate and strontium titanate - for a range of compositions
