Algorithm exposes the energy pathways that cause super-repellent surfaces to stop working

'Superhydrophobic' surfaces, such as anti-icing or self-cleaning windows, are remarkably effective at repelling water molecules. However, they may suddenly—and dramatically—lose their superhydrophobic features. A*STAR researchers have now identified a cause for the widespread 'wetting transition' by pinpointing how infiltration of a single microscopic groove can cause such an event.
