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.

Medical devices and implements with liquid-impregnated surfaces

In certain embodiments, the invention relates to an article having a liquid-impregnated surface. The surface includes a matrix of solid features (e.g., non-toxic and/or edible features) spaced sufficiently close to stably contain a liquid therebetween or therewithin, wherein the liquid is non-toxic and/or edible. The article may contain, for example, a food or other consumer product, such as ketchup, mustard, or mayonnaise.

Self-lubricating surfaces for food packaging and food processing equipment

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.

Apparatus with a liquid-impregnated surface to facilitate material conveyance

Method for promoting nucleate boiling on an interior surface of a vessel for boiling fluid in an industrial process, the method comprising the steps of: providing the vessel having the interior surface; controllably depositing a scale layer having a non-zero thickness onto the interior surface; monitoring an average thickness, x, of the deposit of the layer; and maintaining the average thickness, x, of the layer below a predetermined value or within a predetermined range of values during the operational life of the vessel, wherein x&#x3c;k/h, wherein k is the effective thermal conductivity of the interior surface of the vessel and h is the heat transfer coefficient at the interior surface of the vessel in contact with the boiling fluid.

Methods for promoting nucleate boiling

Textured surface for increasing Leidenfrost temperature. The texture comprises of surface features over multiple length scales&#x2014;from micro to nanoscale&#x2014;wherein the features at each length scale have a size, aspect ratio, and spacing selected to increase the Leidenfrost temperature. The structure includes an array of microscale structures disposed on the surface, the structure having size, aspect ratio and spacing selected to increase Leidenfrost temperature. The microscale structures may also include nanoscale structures on their surface to create a hierarchical structure. The structures result in an increased Leidenfrost temperature.

Superwetting surfaces for diminishing leidenfrost effect, methods of making and devices incorporating the same

In certain embodiments, the invention relates to an article having a liquid-impregnated surface. The surface includes a matrix of solid features (e.g., non-toxic and/or edible features) spaced sufficiently close to stably contain a liquid therebetween or therewithin, wherein the liquid is non-toxic and/or edible. The article may contain, for example, a food or other consumer product, such as ketchup, mustard, or mayonnaize.
