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.
