Molecular Structure of an Ultrastable Glass (image) University of Chicago Share Print E-Mail Caption This image shows the molecular configuration of a simulated ultrastable glass. The purple and greenish-blue spheres represent two different types of atoms (phosphorus and nickel, respectively) that were introduced onto the substrate (the pink spheres) a few at a time in a molecular dynamics simulation, mimicking the vapor deposition process as it occurs in laboratory experiments.
