摘要： In some embodiments, a method of producing a liquid-impregnated surface includes forming a solid particle solution including a plurality of solid particles with an average dimension of between about 5nm and about 200µm. The solid particle solution is applied to a surface by spray-depositing the solid particle solution onto the surface. An impregnating liquid is also applied to the surface. The plurality of solid particles and the impregnating liquid collectively form a liquid-impregnated surface. The impregnating liquid can be applied after the solid particle solution is applied, or the solid particle solution can include the impregnating liquid, such that the solid particle solution and the impregnating liquid are concurrently spray-deposited onto the surface.

摘要： A container for housing a contact liquid includes a liquid-impregnated surface in contact with a contact liquid. The liquid-impregnated surface includes a first surface having a first roll off angle. A plurality of solid features are disposed on the first surface, such that a plurality of interstitial regions are defined between the plurality of solid features. An impregnating liquid is disposed in the interstitial regions and the interstitial regions are configured such that that the impregnating liquid is retained in the interstitial regions by capillary forces. The impregnating liquid disposed in the interstitial regions defines a second surface having a second roll off angle less than the first roll off angle. The container further includes a nucleation mechanism configured to nucleate and destabilize a film of the contact liquid disposed on the liquid-impregnated surface, such that the film of the contact liquid can be rapidly removed from the container.

摘要： An article with a liquid-impregnated surface (120), the surface (120) having a matrix of features (124) thereupon, spaced sufficiently close to stably contain a liquid (126) therebetween or therewithin, and preferable also a thin film thereupon. The surface (120) provides the article with advantageous non-wetting properties. Compared to previous non-wetting surfaces (104), which include a gas (110) (e.g., air) entrained within surface textures (108), these liquid-impregnated surfaces (120) are resistant to impalement and frost formation, and are therefore more robust.
摘要翻译：具有液体浸渍表面（120）的物品，表面（120）具有特征（124）的矩阵，其间隔足够接近以稳定地容纳其间或其中的液体（126），并且还优选薄膜。表面（120）为制品提供有利的非润湿性质。与先前的非润湿表面（104）相比，其包括夹带在表面纹理（108）内的气体（110）（例如空气），这些浸渍液体的表面（120）耐冲击和霜冻形成，因此更健壮

摘要： Hierarchical nanostructures and methods of fabrication. The structures include particles having a metal oxide outer shell with metal oxide wires extending from the outer shell. A multiscale structure according to the invention has particles above and below a critical size wherein the particles above the critical size have wires extending from the surface. These structures may be fabricated from a mixture prepared of relatively smaller metal particles having a size threshold below a threshold for nanowire formation and of relatively larger metal particles having a size above the threshold for nanowire formation. The mixture is oxidized at a selected temperature and for a selected time whereby the relatively smaller particles sinter and nanowires grow on the relatively larger particles thereby creating tunable hierarchical structures with metal-to-metal contact between the particles.

摘要： Articles and methods for forming liquid surface films on the interior surfaces of containers for holding one or more products comprising one or more Bingham plastic materials. Bingham plastic materials behave as a solid under no or low shear stress, and behave as viscous liquids when an applied shear stress exceeds a yield stress. In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle with respect to the interior surface of the container, of about 0 degrees. The liquid-product interface in contact with the interior surface, makes a contact angle with respect to the interior surface, of less about 60°.
