A device and methods for performing biological or chemical analysis is provided. The device includes an array of three-dimensional microcolumns projecting away from a support plate. Each microcolumn has a relatively planar, first surface remote from the support plate. An array of multiple, different biological materials may be attached to the first surface. The device, when used in combination with existent micro-titer well plates, can improve efficiency of binding assays using microarrays for high-throughput capacity.

Microcolumn-platform based array for high-throughput analysis

An improvement in a method of forming ceramic articles comprising an oil component or extrusion aid, the improvement including removing a substantial portion of the oil component, prior to firing, by applying a solvent to the green ceramic article to dissolve the oil component.

Method of forming ceramic articles

A polyester having less than 50 hydrogen-carbon bonds per 1000 molecular weight units exhibits very low optical loss in the range of wavelengths commonly used for optical communication, and exhibits other physical properties suitable for use as a waveguide core material and/or a waveguide cladding material in optical fibers and/or planar optical devices.

Highly-halogenated low optical loss polymer

The invention provides improved high contrast, photopolymerizable compositions suitable for producing high contrast waveguides. The high contrast, photopolymerizable compositions of this invention include a nitrone compound component. The photosensitive composition is an admixture of a free radical polymerizable acrylate or methacrylate component having at least two ethylenically unsaturated groups, a photoinitiator, and a nitrone compound.

Nitrone compounds as photopolymer polymerization inhibitors and contrast

This invention relates to novel nylon compositions that maintain their appearance on weathering in the presence of U.V. light and a process of their manufacture. These composition are useful in a variety of applications including fibers, molded plastic parts, films and coatings.

Nylon compositions for UV stability

The invention relates to novel cinnamamides, a process for their manufacture and their use as UV absorbers. The cinnamamides of the invention may be used as UV absorbers in a variety of engineered resins such as polyamides (especially nylon 6 and 6,6), polycarbonates, polyacetals, polysulfones, polyimides, polyaryletherketones, and polyesters, (especially PET and PBT), as well as, other polymers such as polyvinylchloride and polyolefins (polyethylenes and polypropylenes).

Cinnamamides and their use as stabilizers

Optically active (optically non-linear or electro-optically active) waveguides are formed by depositing a layer of organic material, typically polymeric material, comprising one or more opticaly active components, and subjecting predetermined regions of the layer to actinic radiation to alter the refractive index of these regions.

Method for forming optically active waveguides

Homopolymers and copolymers with an acrylic backbone chain having pendant side-chains containing a nitrone functional group undergo change in refractive index upon exposure to actinic radiation. Waveguides are 'written' in films containing such polymers by exposing predetermined areas to sufficient actinic radiation to change the refractive index.

Polymeric nitrones having an acrylic backbone chain

Polymer compositions having a styrene-derived backbone chain and having pendant side chains containing a nitrone functional group undergo changes in refractive index upon exposure to actinic radiation. Waveguides are 'written' in films containing such polymers by exposing predetermined areas to sufficient radiation to change the refractive index.

Homopolymers and copolymers with an acrylic backbone chain having pendant side-chains containing a nitrone functional group undergo change in refractive index upon exposure to actinic radiation. Waveguides are 'written'in films containing such polymers by exposing predtermined areas to sufficient actinic radiation to change the refractive index.

The present invention relates to foam compositions which are expanded with hydrohalocarbon blowing agents in the presence of additives which decrease the formation of haloalkenes during the polymerization. Thus, the present invention provides compositions comprising polyisocyanate, polyol, hydrohalocarbon blowing agent, catalyst, surfactant, and at least one additive wherein the additive is capable of decreasing the amount of decomposition of said dehydrohalocarbon blowing agent to haloalkenes during polymerization of the polyisocyanate and the polyol. Depending upon the polyol and polyisocyanate used and the quantity of polyisocyanate used, the compositions may be used in pour-in-place molded foams; rigid urethane spray foams; rigid high and low density foams for slabstock, froth foams, and molded foams; rigid laminated boardstock; or specialty foams.
