摘要： Described herein are medical devices and medical implements with high lubricity to flesh (or biological fluid) and/or inhibited nucleation on its surface. The device has a surface comprising an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between said solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface.

摘要： This invention relates generally to an article that includes a base substrate, an intermediate layer including at least one element or compound selected from titanium, chromium, indium, zirconium, tungsten, and titanium nitride on the base substrate, and a hydrophobic coating on the base substrate, wherein the hydrophobic coating includes a rare earth element material (e.g., a rare earth oxide, a rare earth carbide, a rare earth nitride, a rare earth fluoride, and/or a rare earth boride). An exposed surface of the hydrophobic coating has a dynamic contact angle with water of at least about 90 degrees. A method of manufacturing the article includes providing the base substrate and forming an intermediate layer coating on the base substrate (e.g., through sintering or sputtering) and then forming a hydrophobic coating on the intermediate layer (e.g., through sintering or sputtering).

摘要： The articles and methods described herein provide a way to manipulate condensation on a surface by micro/nano-engineering textures on the surface and filling the spaces between the texture features with an impregnating liquid that is stably held therebetween or therewithin. The articles and methods allow droplets of water, or other condensed phases, even in micrometer size range, to easily shed from the surface, thereby enhancing contact between a condensing species and the condensing surface. It has been found that dropwise condensation is enhanced by the use of an impregnating (secondary) liquid that has a relatively high surface tension, and, even more preferably, an impregnating liquid that has both a high surface tension and a low viscosity.

摘要： Described herein are conduits for conveying fluids and/or solids, the conduits having an interior surface that provide a high-slip boundary condition, thereby facilitating the flow of material therethrough. In some embodiments, the conduit has an interior surface with an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between the solid features, the interior surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the interior surface and regardless of flow, passage, or removal of fluids and/or solids through, into, or out of the conduit.
