摘要： The resistance to wear-induced failures during forming operations of non-ferrous die tooling materials, such as epoxy-based and zinc-based materials, is improved by treating the surface of the die tooling. In one approach, the surface of an organic-containing or metallic substrate is coated with a silicon-modified organic materials and then implanted with ions of an inert gas to transform the organic material to a silicon carbide-rich layer. In the other, nitrogen ions are implanted into the surface of a zinc-based alloy.

摘要： A composite material includes droplets of a liquid crystal material dispersed within a matrix of a photopolymerized polymer. The material is prepared by forming a solution of the liquid crystal material and a monomer, and then polymerizing the monomer with light. The solubility of the liquid crystal material in the polymer is less than in the monomer. As polymerization progresses, a portion of the liquid crystal material separates as a second phase in the polymer matrix. The liquid crystal can be any suitable such material that is soluble in the monomer and less so in the polymer, and the monomer is a polymerizable acrylate or methacrylate. Liquid crystal devices are prepared by forming the composite material between two electrically conducting substrates.

摘要： A sensor and method for detecting biological and chemical agents comprising metal interdigitized electrodes coated with hybrid polymer-based conducting film and an instrument for applying electrical voltage to the electrodes and registering the change in electrical current. The hybrid film also comprises indicator biomolecules encapsulated within the film or attached to it. The bioindicator molecules preferably comprise enzyme acetylcholinesterase. When these indicator biomolecules come in a contact with a pathogen, chemical and/or morphological changes occur in the film and electrical current flowing through the electrodes is modulated. The pathogen comprise inhibitors of enzymes, preferably organophosphates, thiophosphates or phosphonates. The change in current indicates the presence of a biological and chemical agent and is registered.

摘要： A composite material having droplets of a liquid crystal material in a matrix of a coploymer of a multifunctional acrylate, or a mixture of different multifunctional acrylates, and a multifunctional mercaptan is prepared by photopolymerization. The liquid crystal material is initially mixed with a multifunctional acrylate monomer, a multifunctional mercaptan, and a photoinitiator to form a solution. The solution is exposed to ultraviolet light, whereupon the multifunctional acrylate monomer and multifunctional mercaptan copolymerize in a step reaction, and the liquid crystal separates from the copolymer as droplets dispersed throughout the copolymer matrix. The resulting material is placed between transparent, electrically conducting plates to form an electro-optic display device.

摘要： A sensor (10) is provided, which is based on a conductive polymer (16) as the active material to measure the concentration of alcohol in gasoline. This information is then sent to the engine to immediately adjust the air:fuel ratio, which is critical in these alternate fuel systems for the smooth operation of the engine. The sensor of the invention comprises the conductive polymer and a pair of sensing electrodes (12, 14) associated with the conductive polymer. Most conveniently, the sensing electrodes are arranged in an interdigitated fashion and are coated with the conducting polymer. Certain conducting polymers have been found whose resistance changes as a function of alcohol, e.g., methanol, concentration. Since the resistance of the conducting polymer is related to the alcohol concentration, this information can be processed by a microprocessor, which can then make the necessary adjustments in the air:fuel ratio. The device of this invention can be much smaller and much less expensive than the prior art dielectric-based sensor and yet retain precision and accuracy (.+-.0.5% required) with fast response time.

摘要： A sensor for monitoring the water content and the acid content in the presence of water in nonaqueous media can be incorporated into a monitoring system for monitoring the quality of nonaqueous fluids in equipment or vehicles. The sensor comprises an insulating substrate; electrodes formed on the substrate in an interdigitated pattern; and a conductive polymer deposited over the interdigitated electrodes which bridges between adjacent digits of the electrodes. The monitoring system incorporating the sensor comprises a control module for measuring the conductivity of the sensor. The control module is preprogrammed to compare the measured conductivity to a predetermined level indicative of an unacceptable level of degradation. The sensor is made by depositing electrodes on an insulating substrate; depositing a conductive polymer over the electrodes in an amount sufficient to bridge between the electrodes; and neutralizing the conductive polymer to an insulating form. A method of sensing water and acid in the presence of water in nonaqueous media exposes an insulating form of a conductive polymer to a nonaqueous medium and monitors the conductivity of said conductive polymer, as the nonaqueous medium is used. The conductive polymer reversibly increases conductivity in measurable amounts with increasing acid and/or water content due to protonation by the acid or hydration by the water.
