Claim Text:
1. A heat exchange structure, comprising: a substrate including a plurality of non-through holes disposed therein, the plurality of non-through holes being arranged in a microstructure pattern across a primary face of the substrate, each of the plurality of non-through holes having a continuous sidewall, each continuous sidewall preventing fluid communication with others of the plurality of non-through holes in the microstructure pattern below the primary face of the substrate; a first nanostructure layer disposed on each bottom of the plurality of non-through holes and on each continuous sidewall of the plurality of non-through holes, the first nanostructure layer having a nanotextured topography of greater surface area than that of said each bottom and said each continuous sidewall disposed thereunder, and the first nanostructure layer including a plurality of vapor nucleation sites collectively disposed between individual nanostructures along the nanotextured topography; and a second nanostructure layer disposed on the primary face of the substrate, wherein the first nanostructure layer disposed on said each bottom and said each sidewall of the plurality of non-through holes is non-wetting relative to a given liquid, and wherein the second nanostructure layer disposed on the primary face of the substrate is wetting relative to the liquid.
