Patent number: 11859018Abstract: The present disclosure provides peptoid-based chelating ligands, corresponding cyclic peptoids, and methods of making thereof. Functional groups may be tailored for high metal binding affinity and selectivity. The side chains of a cyclic peptoid according to the present disclosure may be selected based on, for example, high affinity for actinide or other metal ions, selectivity for actinide or other metal ions, the ability to recover a metal once it is bound to the peptoid, and whether the overall peptoid should be hydrophobic or hydrophilic. Unlike siderophores, peptoid-based chelating ligands of the present disclosure are not readily hydrolyzed under physiological conditions. Therefore, peptoid-based chelating ligands may be, for example, used to treat actinide (e.g., iron and lead) poisoning in vivo. Moreover, peptoid-based chelating ligands of the present disclosure may be used for medical imaging, chelation therapy, drug delivery, and separation technologies, for example.Type: GrantFiled: January 14, 2022Date of Patent: January 2, 2024Assignee: TRIAD NATIONAL SECURITY, LLCInventors: Robert F. Williams, David Owen Baumann, John Cameron Gordon

Patent number: 10550139Abstract: Embodiments of the present disclosure relate generally to novel achiral and chiral sulfur-, nitrogen- and phosphorus-containing ligands, designated as NNS-type, P(O)NS-type, PNS-type, SNNS-type, SNNP(O)-type, or SNNP-type polydentate ligands and transition metal complexes of these ligands, including iridium complexes having PNS-type and NNS-type ligands. The catalysts derived from these ligands and transition metal complexes may be used in a wide range of catalytic reactions, including hydrogenation and transfer hydrogenation of unsaturated organic compounds, dehydrogenation of alcohols and boranes, various dehydrogenative couplings, chemoselective hydrogenation of ?,?-unsaturated alcohols, and other catalytic transformations.Type: GrantFiled: December 9, 2016Date of Patent: February 4, 2020Assignee: Triad National Security, LLCInventors: Pavel A. Dub, John Cameron Gordon

Patent number: 9751815Abstract: Embodiments of the present invention are directed to the conversion of a source material (e.g., a depolymerized oligosaccharide mixture, a monomeric sugar, a hydrolysate, or a mixture of monomeric sugars) to intermediate molecules containing 7 to 26 contiguous carbon atoms. These intermediates may also be converted to saturated hydrocarbons. Such saturated hydrocarbons are useful as, for example, fuels.Type: GrantFiled: October 3, 2016Date of Patent: September 5, 2017Assignee: Los Alamos National Security, LLCInventors: Louis A. Silks, Andrew Sutton, Jin Kyung Kim, John Cameron Gordon, Ruilian Wu, David B. Kimball
