Abstract: Selective chelation of bismuth radionuclide ions from a mixture including actinium radionuclide ions involves exposing a ligand to an aqueous solution that includes bismuth radionuclide ions and actinium radionuclide ions under conditions whereby the bismuth radionuclide ions selectively chelate to the ligand for form cationic complexes of the bismuth radionuclide ions. and separating the cationic complexes of the bismuth radionuclide ions from the actinium radionuclide ions. The ligands have a structure based on a 12-membered cyclen ring and may include pendant functional groups that can be derivatized with biological targeting vectors for targeted alpha therapy.

Abstract: Novel zeolites are produced by combining a polar solute, a silicon or phosphorous source, and a structure directing agent. Surfactants and a hydrophobic solvent are added to the previously mixed three species and shaken to disperse the surfactants. The reverse microemulsion is stirred overnight, at about room temperature and then iced for five to ten minutes. A metal source is added vigorously shaken for about two minutes. The mixture is then aged for about two hours at about room temperature. A mineralizer is added and the resultant mixture aged for about two hours at about room temperature. The mixture is heated to about 180° C., for a suitable time period. The final novel product is then isolated.

Abstract: A method for carrying out a catalysis reaction in carbon dioxide comprising contacting a fluid mixture with a catalyst bound to a polymer, the fluid mixture comprising at least one reactant and carbon dioxide, wherein the reactant interacts with the catalyst to form a reaction product. A composition of matter comprises carbon dioxide and a polymer and a reactant present in the carbon dioxide. The polymer has bound thereto a catalyst at a plurality of chains along the length of the polymer, and wherein the reactant interacts with the catalyst to form a reaction product.
