摘要： The invention relates to silk or other materials formed to have predetermined contraction/relaxation characteristics, wherein the contraction/relaxation characteristics are initiated by exposure thereof to predetermined humidity characteristics in the adjacent atmosphere. The materials may comprise a single silk fiber, a bundle of fibers of a predetermined size or diameter, a meshwork of fibers forming a predetermined configuration such as one or more sheets, bundles or other bodies. In this manner, the material can be scaled across a size range of any desired magnitude to produce predetermined force and/or displacement characteristics in association therewith.

摘要： The present invention is directed to synthetic attachment discs made from adhesive nanofibers and/or microfibers that are capable of attaching long fibers to a wide variety of surfaces, and related methods for forming and using them. The synthetic attachment discs of the present invention use very little material relative to prior art systems, while producing a very strong attachment force. Experimental and theoretical evidence are provided to confirm the advantages of thousands of micron-size ‘staple-pins’ and their low peeling angles to enhance the adhesive forces required to peel the synthetic attachment discs. The present invention provides a unique strategy for designing new adhesives that use very little material for various biomedical and material science applications.

摘要： A method of fabricating a cathodic portion of a field emission display includes the steps of producing an array of substantially parallel carbon nanotubes attached at one end to a substantially planar substrate. Then, embedding the nanotubes in a polymer matrix that extends to a plane of attachment of the nanotubes to the planar substrate, wherein the polymer matrix allows an end of the nanotubes distal from the ends attached to the planar substrate, uncovered by the polymer matrix in order to allow electrical contact with each other and with an attached conductor. Next, detaching the array from the planar substrate, thus producing a surface having the formerly attached ends of the nanotubes substantially in a plane, and then attaching the conductor to the array of nanotube ends, uncovered by the polymer matrix and distal to the plane.

摘要： In one or more embodiments, the present invention provides a method of applying or printing structural colors to a substrate that involves pre-treatment of the substrate surface to prevent absorption of the fluid containing the particles. This allows the fluid to maintain their sessile drop shapes and as the water evaporates, the colloidal particles spontaneously assemble within the confined geometry into semi-ordered structures that interact with light to produce structural color. While the pre-treatment may be done in a variety of ways, application of a, hydrophobic and/or oleophobic coating, like 1H-IH,2H-perfluoro-1-dodecene (C10F21—CH═CH2) (perfluoro) monomer, fluoroalkyls, fluorohydroalkyls, cyclo-fluoroalkyls, fluorobenzen, by plasma-enhanced chemical vapor deposition (cold plasma treatment) has been found to be effective, particularly for printing applications. These treated substrates allow production of a wide range of structural colors using binary systems of nanoparticles.
