Argonne Theorists Solve a Long-Standing Fundamental Problem
Trying to understand a system of atoms is like herding gnats - the individual atoms are never at rest and are constantly moving and interacting. When it comes to trying to model the properties and behavior of these kinds of systems, scientists use two fundamentally different pictures of reality, one of which is called "statistical" and the other "dynamical." The two approaches have at times been at odds, but scientists from the U.S. Department of Energy's Argonne National Laboratory announced a way to reconcile the two pictures.
A Virtual Flight Through a Catalyst Particle Finds Evidence of Poisoning
Merging two powerful 3-D X-ray techniques, a team of researchers from the Department of Energy's SLAC National Accelerator Laboratory and Utrecht University in the Netherlands revealed new details of a process known as metal poisoning that clogs the pores of catalyst particles used in gasoline production, causing them to lose effectiveness.
Super Cement's Secret
Mayenite is one smart cement -- it can be turned from an insulator to a transparent conductor and back. It is also suitable for use as semiconductors in flat panel displays. The secret behind mayenite's magic is a tiny change in its chemical composition. In new work in Proceedings of the National Academy of Sciences, researchers show how components called electron anions help to transform crystalline mayenite, also called C12A7, into semiconducting glass.
Poof! The Weird Case of the X-Ray That Came Out Blank
Imagine getting a medical X-ray that comes out blank - as if your bones had vanished. That's what happened when scientists cranked up the intensity of the world's first X-ray laser, at the Department of Energy's SLAC National Accelerator Laboratory, to get a better look at a sample they were studying: The X-rays seemed to go right through it as if it were not there.
