  • Patent number: 11859018
    Abstract: 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.

  • Patent number: 11859039
    Abstract: Branched block copolymers, derived from alkenyl aromatic hydrocarbon-1,3-diene monomer system, and branched polyisoprene homopolymers, derived from isoprene, are obtained by polymerization in the presence of an anionic initiator; at a temperature from 0° C. to 100° C.; followed by coupling with a multifunctional coupling agent of formula (R1O)3Si—Y—Si(OR2)3, wherein R1 and R2 are independently C1-C6 alkyl groups; and Y is a C2-C8 alkylene group. The polymers thus obtained can be used in many applications, including rubber cements having high solids content and low zero shear viscosities, and for producing aqueous latices therefrom.

  • Patent number: 11859041
    Abstract: This disclosure provides new methods for the design and development of ethylene polymerization catalysts, including Group 4 metallocene catalysts such as zirconocenes, which are based on an improved ability to adjust co-monomer incorporation into the polymer. Computational analyses with and without dispersion corrections revealed that designing catalyst scaffolds which induce stabilizing non-covalent dispersion type interactions with incoming ?-olefin co-monomers can be used to modulate co-monomer selectivity into the polyethylene chain. Demonstrated herein is a lack of correlation of computed ??G‡ values against experimental ??G‡ values when the dispersion correction (D3BJ) was disabled, and B3LYP was used in the absence of Grimme's D3 dispersion and Becke-Johnson (BJ) dampening, but a correlation of computed against experimental ??G‡ with B3LYP+D3BJ, which are used to design new catalyst scaffolds.
