Slipperiest liquid surface in the world, researchers say.

This new technique uses a substance called SAMs to create the slipperiest liquid surface in the world. The surface is made of silicon and coated with a SAM. SAMs act as a lubricant between water droplets and the surface. Water can flow quickly or slowly depending on the SAM size, but it’s not uniform across the entire surface. New research shows that this isn’t always the case. At low SAM levels, water flows freely between the SAM molecules and starts sliding off the surface; at higher SAM densities, however, water stays on top of the SAM and doesn’t get away. This could be useful for applications such as heat transfer in pipes, de-icing and anti-fogging, as well
