Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201302083-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A robust directional oil sliding surface</bold> is presented by utilizing re‐entrant micro‐groove arrays inspired from the microgrooves of rice leaf. The overhang micro‐groove arrays are shown to provide two primary goals of "omniphobicty" and "anisotropic sliding" with DI water (<alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgg3t136v0q" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math display="inline" altimg="urn:x-wiley:09359648:adma201302083:equation:adma201302083-math-0003" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi>γ</mml:mi><mml:mrow><mml:mi>l</mml:mi><mml:mi>v</mml:mi></mml:mrow></mml:msub></mml:math></alternatives> = 72.1 mN/m) as well as mineral oil (<alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgg3t136tgx" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math display="inline" altimg="urn:x-wiley:09359648:adma201302083:equation:adma201302083-math-0004" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi>γ</mml:mi><mml:mrow><mml:mi>l</mml:mi><mml:mi>v</mml:mi></mml:mrow></mml:msub></mml:math></alternatives> = 28 mN/m) and conventional photoresist. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3t136s5f" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
