Abstract
Described herein are non-wetting surfaces comprising rare-earth containing ceramics. Furthermore, the surfaces include liquid impregnated within a matrix of micro- or nano-engineered features on the surface. The surfaces are non-wetting and can resist liquid impalement, ice formation, scale formation, hydrate formation, and/or have antifouling properties.
