    Abstract: 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).

    Abstract: 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.

    Abstract translation: 这里描述了用于输送流体和/或固体的导管，该导管具有提供高滑移边界条件的内表面，从而有助于材料流过其中。 在一些实施例中，导管具有带有浸渍液体的内表面和多个微尺度和/或纳米尺度的固体特征，其间隔足够接近以在其间稳定地容纳浸渍液体。 浸渍液填充固体特征之间的空间，内表面在固体特征之间稳定地含有浸渍液体，并且浸渍液体基本上保持在多个固体特征之间的适当位置，而与内表面的取向无关，而与流动无关， 通道，或通过，进入或流出导管的流体和/或固体。
