Abstract: An aluminum substrate is provided with a superhydrophobic surface structure that comprises a porous alumina layer having a hydrophobic coating. The porous alumina layer is created on the aluminum substrate by an anodizing process, and is engineered such that the thickness of the alumina layer and the diameters of the pores have nanoscale values. The anodizing process is performed in two anodizing steps with an intermediate etching step. The superhydrophobic surface provides protection against corrosion by entrapping air in the pores so as to prevent penetration of water to the aluminum metal.

Abstract: A two-beam interference lithography system offers large-area nanopatterning with tunability of pattern periodicities. The tunable feature is achieved by placing two rotatable mirrors in the two expanded beam paths which can conveniently be regulated for the designed pattern periodicities. While the effective interference pattern coverage is mainly determined by the optical coherence length and mirror size, the minimum pattern coverage area is as large as the effective coherence length of the laser and the selected mirror size over a wide range of periodicities.
