  • Method for removal of dissolved metal cations from aqueous fluids using modified capture polymers and tether polymer bearing anchor particles
    Patent number: 8894863
    Abstract: Systems and methods are presented for removing an ionic material from a fluid using a capture polymer that sequesters the ionic material and an anchor particle bearing a tethering polymer. The tethering polymer complexes with the capture polymer after the capture polymer has sequestered the ionic material, thereby affixing a complex of capture polymer and ionic material to the anchor particle to form a removable complex. The removable material can be segregated from the fluid via a removal system, thereby removing the ionic material from the fluid.

  • Volatile debonder formulations for papermaking
    Patent number: 8747615
    Abstract: Formulations and methods for papermaking use one or more volatile debonders, where the volatile debonder forms a solution or an emulsion with water in a paper precursor, and where the volatile debonder is evaporable from the paper precursor before the paper precursor is completely dried to form a paper sheet during papermaking. Two volatile debonders having different boiling points can be used, where they are miscible in water and in each other, and where one volatile debonder has a higher molecular weight and the other volatile debonder has a lower boiling point.
