The present invention is a polyol method for making composite particles of two or more immiscible transition metals, where these particles are of nanoscale dimensions, and where the constituent metals are of essentially nanocrystalline morphology. The method of the invention has the steps of (1) dissolving or suspending two or more precursor metal compounds in an alcohol or polyol (diol, triol, etc. ) solution, and (2) taking the solution or suspension to a temperature where the metal compound reduces, causing the first and second metals to form nanoscale composites. The term “polyol solution” will be used herein to describe solutions that contain either alcohol or polyol.

This invention pertains to a process for preparing diacetylenics, to diacetylenic compounds and to reduced diacetylenic compounds. The process includes the steps of reacting coupling an acetylenic acid in presence of cupric chloride in Ethylamine and hydroxylamine hydrochloride to form a diacetylenic diacid; reacting the diacetylenic diacid with a lithium compound, trimethylsilyl chloride and hydrochloric acid to form a diacetylenic compound; and reducing the diacetylenic compound to a reduced diacetylenic compound. The diacetylenic compounds have the formula COOH—(CH ) —C≡C—C≡C—(CH ) —C( O)—R or R—C( O)—(CH ) —C≡C—C≡C—(CH ) —C( O)—R and the reduced cyclic diacetylenic compounds have the formula COOH—(CH ) —C≡C—C≡C—(CH ) —CH —R or R—CH —(CH ) —C≡C—C≡C—(CH ) —CH —R, where m is 1-18 and R is selected from alkyl groups of 1-10 and cyclic groups containing 6-35 carbon atoms and aryl moieties.

A coating composite is provided for a platform surface of an antenna array for, when applied to the platform, affording isolation of radiating and receiving antennas of the array. The coating composite includes a plurality of conductively coated elongate tubes dispersed in an insulating polymer matrix at a volume loading density approaching that at which the composite begins to conduct electrically over macroscopic distances, i. e. , close to the percolation threshold. The tubes are preferably comprised of microtubules comprised of biologically-derived, high-aspect rod-shaped particles of microscopic dimensions having an electroless plated metal coating thereon.

A colorimetric detector for chemical and biological agents or toxins is made of a giant unilamellar vesicle (GUV) having a membrane bilayer which is polymerized to stabilize the giant unilamellar vesicle and to provide extended conjugated polymer backbone, and the GUV has at least one incorporated molecular recognition site for the chemical and biological agents or toxins. The GUVs are about 10-300 microns and preferably made of a polymerizable diacetylenic GUV where the acyl chains are crosslinked. When the agents or toxins bind to the recognition site the detector exhibits a color change. The detector can be used in a colorimetric detector apparatus where the samples can be present in air or in water.

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. When reactive monomers are allowed to polymerize in the water phase to form particles, the surface of the particles have cavities that are the mirror image of the imprint group.
