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.
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.
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
A $250,000 contribution today by ATT Arkansas in honor of outgoing board member Patti Upton gave a significant boost to the nanomedicine research program in the Winthrop P. Rockefeller Cancer Institute at the University of Arkansas for Medical Sciences.
Today, IBM researchers unveiled a new generation of experimental computer chips designed to emulate the brain's abilities for perception, action and cognition. The technology could yield many orders of magnitude less power consumption and space than used in today's computers.
For years, scientists have been trying to create special materials with a negative refractive index - their optical properties are quite different from those of normal materials. Researchers at the TU Vienna could now show that even common metals can have a negative refractive index, if they are placed in a magnetic field.
A team led by researchers at Stanford and Harvard universities has not only created a new material for high-speed organic semiconductors, it has come up with a new approach that can take months, even years, off the development timeline.
