Abstract: The present invention is directed to a method for making a conformal antenna on a surface by providing a composition comprising a polymer matrix and a plurality of metalized tubules and applying the composition to the surface as two parallel wires connected at their ends to make a closed loop with one of the parallel wires broken in the middle. Also disclosed is an alternate method for making a conformal antenna on a surface by spraying a first material comprising a polymer matrix onto the surface and simultaneously spraying a second material comprising a plurality of metalized tubules and a coagulant onto the surface, wherein the first and second materials mix together during the spraying.

Abstract: This invention pertains to a product and a method for preparing same. The product is an electrically conducting metallized fibers and a non-conducting composite containing the metallized fibers. In a preferred embodiment, the product is a composite of metallized cellulose fibers disposed in an electrically non-conducting matrix. The method includes the steps of hydrating cellulose fibers to prevent absorption of chemical reagents; activating the cellulose surface of the fibers for metal deposition; removing from the fibers excess activator and reagents used in the activation; drying the fibers to a free-flowing condition whereby the fibers acquire the color of the activator by virtue of its deposition on the fibers; metallizing the fibers to deposit thereon a metal capable of absorbing electromagnetic radiation; drying the metallized fibers whereby they are free-flowing; and forming a composite composed of an electrically non-conductive matrix having dispersed therein the matallized fibers.

Abstract: The present invention provides microwave attenuating, filled composite materials which contain a polymer or ceramic matrix and metallic tubules and processes for making the same and devices which contain such materials.

Abstract: Provided is an electroless iron bath capable of depositing a ferromagnetic FeB coating onto Pd/Sn-catalyzed substrates at room temperature without the need for an accompanying galvanic couple. The new electroless iron bath is comprised of Fe2+ as the metal source, citrate as the metal chelator, boric acid buffer as the pH controller, and borohydride as the reductant. Surface analysis following plating confirms the deposition of an amorphous FeB coating onto the surface of Pd/Sn-catalyzed cellulose microfibers.

Abstract: Enzymes are modified by incorporating anchor sites for linking the enzymes to a target surface without destroying the catalytic activity of the enzymes. A stable carrier to accommodate and bind the selected enzyme is constructed, and the enzyme is non-covalently linked to the carrier, generally through metal salts of iminodiacetate.

Abstract: A method of making a molecularly imprinted porous structure makes use of a surfactant analog of the molecule to be imprinted that has the imprint molecule portion serving as the surfactant headgroup. The surfactant analog is allowed to self-assemble in a mixture to create at least one supramolecular structure having exposed imprint groups. The imprinted porous structure is formed by adding reactive monomers to the mixture and allowing the monomers to polymerize, with the supramolecular structure serving as a template. The resulting solid structure has a shape that is complementary to the shape of the supramolecular structure and has cavities that are the mirror image of the imprint group. Similarly, molecularly imprinted particles may be made by using the surfactant to create a water-in-oil microemulsion wherein the imprint groups are exposed to the water phase.

Abstract: Tubules which contain an active agent in their lumen and compositions containing such microtubules are effective for providing a slow, controlled release of the active agent. Such microtubules are useful in the production of coating compositions for the protection of surfaces coming into contact with water, adhesive resins for the production of laminated wood products, and devices for dispensing pesticides.
