    摘要: Articles having surfaces with enhanced wetting properties are presented. One embodiment is an article having a surface configured for promoting a phase transformation from a liquid phase to a vapor phase. The article comprises an element comprising a surface disposed to be in contact with a liquid to be transformed to a vapor, and the surface comprises a plurality of surface features having a median feature size, a, and a median feature spacing, b, such that the ratio b/a is up to about 8. The surface comprises a material disposed to contact the liquid, and this material has a nominal wettability sufficient to generate a nominal contact angle of up to about 80 degrees with a drop of the liquid. Another embodiment is a fuel rod for a nuclear reactor comprising a surface configured as described above.
