    摘要： A personal artificial transpiration cooling system having a transpiration surface with a substrate, a transpiration membrane layer which is spaced from the substrate layer by one or more spacers to define one or more interior fluid flow channels between a first surface of the transpiration membrane layer and the substrate; and a stoma layer disposed adjacent a second surface of the permeable membrane layer, the stoma layer being spaced from the second surface of permeable membrane layer by a predetermined distance to define one or more cavities disposed between pores in the at least one stoma layer and the second surface of the permeable membrane layer. A fluid reservoir is provided in fluid communication with the one or more interior fluid flow channels, while the transpiration surface is configured to be worn by a human or an animal and the fluid reservoir is designed to be supported, in use, by the human or animal wearing the transpiration surface.

    摘要： A Heat Exchanger comprising a three-dimensional ordered microstructure material within a shell. The three-dimensional ordered microstructure material has dimensions that allow for large surface area to volume ratios, between 300 and 15000 m2/m3. Alternatively the three-dimensional ordered microstructure may have an open volume fraction between 0.4 and 0.6. The three-dimensional ordered microstructure may be comprised of hollow truss elements and partially filled with a thermally conductive material or a fluid. The Heat Exchanger has a heat transfer coefficient multiplied by the surface area to volume ratio between 3.7*107 and 7*109 Watts per M3K.

    摘要： A photonic device is provided having a two or three-dimensionally periodic structure of interconnected members with alterable spacing between the members. The structure is composed of a shape memory polymer configured to be thermo-mechanically tunable to display a plurality of optical properties under a series of temperature changes and stress. A method of producing a photonic device based on a shape memory polymer is provided. A mold, having a two or three-dimensionally periodic structure of interconnected components with a characteristic spacing between the components, is infiltrated with a shape memory polymer precursor to form a composite structure. The composite structure is solidified. The mold is removed from the composite structure to form a photonic device as an inverse replica of the mold.
