Abstract: Stable highly active supported copper based catalysts of copper oxide or elemental copper crystallites supported on mechanically stable aluminum oxide are disclosed. These catalysts are characterized by high surface area, small copper crystallite size, and high metal loading. The average crystallite size of the copper compound is from about 20 to about 300 A, the copper loading is from about 10 to about 35 weight percent, the average particle diameter is from about 0.1 mm to about 10 mm, and the total surface area is from about 20 to about 400 square meters per gram. The catalysts are useful for hydration of nitrites to amides, especially hydration of acrylonitrile to acrylamide. The catalysts are distinguished by high mechanical stability, extended lifetime, and excellent resistance to hydration and copper leaching.

Abstract: The embodiments of the present disclosure present systems and methods for the reversible solubilization of (aryl ether ketones) (PAEKs). A thioacetalization process is employed to modify the PAEKs into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. This modification allowing selected analysis techniques to be more easily performed on PAEKs, such as gel permeation chromatography. The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for non-destructive characterization of the PAEK. Advantageously, the thioacetalization process is generally applicable to a broad range of PAEKs, unlike presently known methods of solubilizing PAEKs. Solubilization of PAEKs further expands the utility of the PAEKs, opening up additional routes to chemical modification of PAEKs, as well as allowing for the possibility of processing PAEKs from solution.

Abstract: A manufacturing process, which includes: (i) preparing a preform; (ii) laying the preform within a mold; (iii) heating the mold to a predetermined temperature; and (iv) injecting a modified resin system, wherein the modified resin system is formulated to have a viscosity below a threshold viscosity at a specific temperature and a high level of toughness. In one embodiment, the modified resin system contains a combination of epoxies, a curing agent, core-shell rubber particles, a thermoplastic material in an amount of less than 7% by weight, wherein in a cured condition, the thermoplastic material is separated into aggregate domains from the base resin, each aggregate domain having an island-like morphology.

Abstract: A resin-rich peel ply that does not leave behind residual fibers after peeling and can work well with different resin-based composite substrates. The resin-rich peel ply is composed of a woven fabric impregnated with a resin matrix different from the resin matrix of the composite substrate. The peel ply is designed such that, upon manual removal of the peel ply from the composite substrate's surface, a thin film of the peel ply resin remains on the composite substrate's surface to create a bondable surface capable of bonding with another composite substrate, but no fibrous material from the woven fabric remains on the same surface.
