Karen A. SCHERER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12215177
    Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile. An internal cavity may be formed when functionalizing the (meth)acrylic polymer or copolymer in the presence of a hindered amine base. When appropriately functionalized, the macroparticulates may be used to sequester a contaminant from a substance in need of contaminant remediation, such as produced water or flowback water from a wellbore job site. Reclaimed water obtained from the macroparticulates may be utilized to form a treatment fluid. The macroparticulates may be located within a continuous flow line, particularly within a removable cartridge, to promote removal of at least one contaminant from a substance in need of contaminant remediation.

  • Publication number: 20220259351
    Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile, such as iminodiacetic acid or ethylenediamine. When the epoxide-containing (meth)acrylic polymer or copolymer is formed into a predetermined shape before reaction with the compound bearing the nitrogen nucleophile, a profile of the predetermined shape may be at least partially maintained and undergo expansion in the course of forming the reaction product, thereby producing macroparticulates having a larger volume than the predetermined shape itself. An internal cavity may be formed when generating the macroparticulates in this manner. Optionally, a hexasubstituted benzene or a supramolecular receptor may be adhered to a surface portion of the macroparticulates, either covalently or non-covalently.
