Predicting forces between oddly shaped nanoparticles: Simplified model of van der Waals forces will allow previously impossible simulations of how faceted nanoparticles self-assemble into larger structures

Materials scientists have devised a simplified method for calculating the forces that cause nanoparticles to self-assemble. With this new model and graphical user interface, researchers will be able to make previously impossible predictions about how nanoparticles with a wide variety of shapes will interact with one another. The new method offers opportunities for rationally designing such particles for a wide range of applications from harnessing solar energy to driving catalytic reactions.
