    摘要: A novel omniphobic surface coating is disclosed that provides both high oil-repellency and high-water repellency to the coated surface. The coating may contain perfluoropolyether (PFPE) or a similar fluorinated or perfluorinated polymer, as well as a hardener and a catalyst. One or more surfactants or viscosifiers may also be added. Further, the coating may contain one or more functional additives, including, but not limited to, coloring agents, anti-corrosive agents, anti-fouling agents, water-repellent agents, and/or oil-repellent agents. Methods for formulating the novel omniphobic surface coating are also described. Such methods include preparing a first part of the coating, which may contain, at minimum, a polymer such as PFPE or a similar fluorinated or perfluorinated polymer, and a suitable solvent; preparing a second part of the coating, which is a water-free system that may contain, at minimum, a hardener and a catalyst; and combining the first part and the second part together.

    摘要: Methods and apparatus for displaying information from a three dimensional imaging data cube, having particular application in ophthalmology, are disclosed. The method of the present invention slices 3D imaging data along curved surfaces that match anatomical layers, and comprising four steps: a locating step in which anatomical layers are located; a selecting step in which a slicing surface is selected based on the locations of the anatomical layers; an extracting step, wherein the user extracts data values that fall on the slicing surface selected; and a displaying step in which the data values extracted are displayed as a three dimensional image. The apparatus of the subject invention comprises hardware and software that employ the method of the subject invention to display improved anatomical 3D images.
