  • Compositions, methods, and devices for capturing phosphate from water
    Patent number: 11136251
    Abstract: The present disclosure provides compositions, methods, and devices for sensing, detecting, and/or selectively capturing phosphate from water. An exemplary method includes: contacting a ligand or a rare earth metal complex of a ligand as described herein with an aqueous phosphate-containing medium at a pH of 5 to 12 under conditions sufficient to bind phosphate (e.g., reversibly bind phosphate). In certain embodiments, the method further includes releasing the bound phosphate by contacting the bound phosphate complex with an aqueous medium at a pH of 0 to 4 under conditions sufficient to release the bound phosphate.

  • Process for isolating C5 sugars from biomass hydrolyzate
    Patent number: 10407453
    Abstract: Provided are processes for isolating hemicellulose-based sugar from a biomass. The process includes providing a biomass hydrolyzate including a C5 sugar, forming a boronic ester or diester of the C5 sugar, extracting the boronic ester of diester of the C5 sugar, precipitating the C5 sugar using a boron capture agent, and isolating the C5 sugar from the precipitate. The isolated C5 sugar is provided in dry form.
