Abstract

<abstract abstract-type="graphical" xml:lang="en" id="admi201400480-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Hierarchical micro/nanostructured super­hydrophobic surfaces</bold> are developed to control the nucleation, growth, and departure of condensate droplets on copper substrates. The microscale roughness elements on the hierarchical surface yield a 40% higher droplet growth rate and a 300% increase in cumulative droplet departure volume as compared to superhydrophobic surfaces with nanostructures alone. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3w99bbjs" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
