Structural Phase Transition In Minute Detail On A Very Fast Timescale–A Path To Improved Computer Memories (Argonne National Lab)

popularity

A new technical paper titled “X-ray nanodiffraction imaging reveals distinct nanoscopic dynamics of an ultrafast phase transition” was published by researchers at Argonne National Lab, UCSD, and the University of Wisconsin–Madison.

According to Argonne National Lab’s news release,” researchers have for the first time been able to look at a structural phase transition in minute detail on a very fast timescale. The scientists made X-ray ​photographs” that are spaced less than one-tenth of 1 billionth of a second apart through a technique called nanodiffraction microscopy. ​A typical video might play at 30 frames per second, so this is approximately a slow-motion video that can resolve dynamics that are extremely fast,” said Haidan Wen, a physicist at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.  These advanced microscope methods could lead the way for improved computer memories, according to the article.
