News: Theory and Simulation

In an article published online July 21 in the journal Nature Communications, Panagiotopoulos and colleagues propose that pure photonic crystals could be created from a mixture in which colloidal particles are dispersed in a polymer melt.
In today’s issue of the journal Nature, a Letter describes unambiguous evidence for a liquid-liquid transition in a modern model of water—the ST2 model—at deep supercoolings, and even shows coexistence between the two liquid forms, which differ in density and average coordination number.
The cover of the January 2014 issue of Rheology Bulletin features a striking color rendition of the structure of a colloidal gel, obtained via dynamic simulation of the structural evolution of 750,000 attractive hard spheres.
