  • Patent number: 9970075
    Abstract: A sulfonamide based rare earth element ion separation media and method of synthesis and use are provided. A bed or column of sulfonamide resin for separations can be prepared by exposing a sulfonate resin to chlorosulfonic acid to form a sulfonyl chloride resin; exposing the sulfonyl chloride resin to aqueous ammonia to form a sulfonamide resin; and then packing the sulfonamide resin into a separation column. Mixtures of lanthanide and other rare earth ions with very similar atomic radii and characteristics can be separated by flowing a mixture of lanthanide ions through a bed of sulfonamide resin followed by a mobile phase of an organic acid such as lactic acid to elute the separated rare earth element ions separated by the sulfonamide resin. Collected fractions of eluate can also be recycled through the sulfonamide media.

    Abstract: A method for creating a non-adhesive, water-absorbent wound dressing includes creating a mixture of monomers, crosslinker, initiator, and solvent, initiating polymerization of the monomers to begin polymerization of the monomers; quenching the polymerization of the monomers when the mixture has a viscosity suitable for electrospinning; electrospinning the polymer mixture to form a fibrous membrane; and thereafter further polymerizing and crosslinking the fibrous membrane. The monomers are chosen from select species and, following this process, provide wound dressings that are nonadherent to a wound so as to be potentially reusable; superabsorbent; non-biofouling. With the addition of antimicrobial cations, the wound dressings also provide antimicrobial properties.
