Abstract: Described herein is a an adsorbent and/or absorbent composition, a method of preparing the adsorbent and/or absorbent composition, and method of treating a fluid stream with the adsorbent and/or absorbent composition. Alumina and carbon are combined with polyacrylamide (PAM) powder and water in preferred proportions and impregnates such as Group 1A metal hydroxides. Group 7A salts of Group 1A metals optionally can be added.

Abstract: Disclosed herein is a method of making a porous molecular structure from a solution comprising an insoluble metal containing material and a ligand-providing material. In some embodiments, the porous molecular structure can be a Metal-Organic Framework (MOF). Ionic metal salts are the most common type of metal source for MOF production, but dissolution of metal salts complicates solvent recycling and creates corrosion and oxidation issues through evolved nitrate and chloride anions. Elucidating information that leads toward more efficient production of these versatile nanomaterials, while extending the knowledge base of how MOFs form during reaction, is critical to advancing MOF materials into large-scale use. Disclosed herein are improved methods for controlled synthesis of porous molecular structures such as MOFs comprising a solution-based synthesis with insoluble metallic precursor.

Abstract: A process for cleaning (e.g., desmutting) an aluminum surface, using compositions free of nitric acid and chromic acid and comprising, in one embodiment, an oxidant and at least one mineral acid salt. In another embodiment, the process uses a composition free of nitric acid and chromic acid and comprising an oxidant, at least one mineral acid salt, and a complexing agent which is a salt of an organic acid. Due at least in part to the absence of nitric and chromic acids, and in particular, strong mineral acids, the cleaning processes of the present invention remove smut residues from aluminum surfaces without significant etching of the aluminum.

Abstract: The present invention provides a non-cyanide aqueous acidic immersion plating solution having a pH of from about 3.5 to about 6.5 and comprising zinc ions, nickel ions and/or cobalt iron ions, and fluoride ions. In one embodiment the immersion plating solutions of the invention also contain at least one inhibitor containing one or more nitrogen atoms, sulfur atoms, or both nitrogen and sulfur atoms. The present invention also relates to methods for depositing zinc alloy protective coatings on aluminum and aluminum alloy substrates comprising immersing the aluminum or aluminum alloy substrate in the non-cyanide acidic immersion plating solutions of the invention. Optionally, the zinc alloy coated aluminum or aluminum alloy substrate is plated using an electroless or electrolytic metal plating solution.

Abstract: A process for applying a metal coating to a non-conductive substrate without an electroless coating is disclosed. The process includes the step of: a. contacting said substrate with an activator comprising a noble metal/Group IVA metal sol to obtain a treated substrate; b. contacting said treated substrate with a self accelerating and replenishing immersion metal composition comprising a solution of (i) a soluble metal salt whose metal is more noble than said Group IVA metal, (ii) a Group IA metal hydroxide, (iii) a complexing agent comprising an organic material having a cumulative formation constant log K of from about 0.73 to about 21.95 for an ion of the metal of said metal salt. The Group IVA metal is employed in a stoichiometric excess compared to the noble metal, the excess Group IVA metal being in its lowest oxidation state. Self accelerating and replenishing non-formaldehyde immersion metal compositions are also disclosed.
