Abstract:
The present invention provides an apparatus, comprising a first mechanical structure having a first rigid surface, an area of the first rigid surface having a nanostructured surface. The apparatus also includes a second mechanical structure having a second rigid surface and opposing the first mechanical structure. The second rigid surface is cooperable with the nanostructured surface such that a microscopic particle is locatable between the nanostructured surface and the second rigid surface.

Abstract:
An apparatus that comprises a liquid mirror. The liquid mirror includes a liquid that forms an interface with a fluid adjacent to the liquid. The liquid mirror also includes a layer of reflective particles located at the interface, wherein the layer forms a reflective surface.
Abstract:
Provided is an apparatus. In one embodiment, this apparatus includes a substrate having a surface, and a plurality of nanostructures each having a first end and a second end, wherein the first end of each of the plurality of nanostructures is attached to the surface. At least a portion of the second ends of the plurality of nanostructures, in this embodiment, are bent toward one another to form two or more similarly configured clumps each including two or more nanostructures.
Abstract:
An apparatus, comprising a plurality of closed cells disposed on a surface of a substrate. Each of the closed cells has at least one dimension that is less than about 1 millimeter and are configured to hold a medium therein. The apparatus also comprises a foam that contacts the closed cells. The foam has fluid walls that include a surfactant, and bubbles of the foam layer are filled with the medium.
