TL;DR: It is shown how a third factor, re-entrant surface curvature, in conjunction with chemical composition and roughened texture, can be used to design surfaces that display extreme resistance to wetting from a number of liquids with low surface tension, including alkanes such as decane and octane.
Abstract: Understanding the complementary roles of surface energy and roughness on natural nonwetting surfaces has led to the development of a number of biomimetic superhydrophobic surfaces, which exhibit apparent contact angles with water greater than 150 degrees and low contact angle hysteresis. However, superoleophobic surfaces-those that display contact angles greater than 150 degrees with organic liquids having appreciably lower surface tensions than that of water-are extremely rare. Calculations suggest that creating such a surface would require a surface energy lower than that of any known material. We show how a third factor, re-entrant surface curvature, in conjunction with chemical composition and roughened texture, can be used to design surfaces that display extreme resistance to wetting from a number of liquids with low surface tension, including alkanes such as decane and octane.

TL;DR: In this article, a database of surface energies for low index surfaces of 60 metals in the periodic table was used to establish a consistent starting point for models of surface science phenomena, and the accuracy of the database was established in a comparison with other density functional theory results and the calculated surface energy anisotropies were applied in a determination of the equilibrium shape of nano-crystals of Fe, Cu, Mo, Ta, Pt and Pb.

TL;DR: In this paper, the free energy of formation of emulsion drops covered with close-packed monolayers of monodisperse spherical particles was investigated and the possibility of preparing novel solid materials by evaporating solid-stabilised emulsions is also proposed.

TL;DR: In this paper, a semi-theoretical approach was proposed to estimate the surface energy of solids in the absence of direct experimental measurement. But this method was not suitable for the case of high-index surfaces.
