  • Patent number: 8864963
    Abstract: The present invention provides a resin-wafer electrodeionization (RW-EDI) apparatus including cathode and anode electrodes separated by a plurality of porous solid ion exchange resin wafers, which when in use are filled with an aqueous fluid. The apparatus includes one or more wafers comprising a basic ion exchange medium, and preferably includes one or more wafers comprising an acidic ion exchange medium. The wafers are separated from one another by ion exchange membranes. The fluid within the acidic and/or basic ion exchange wafers preferably includes, or is in contact with, a carbonic anhydrase (CA) enzyme to facilitate conversion of bicarbonate ion to carbon dioxide within the acidic medium. A pH suitable for exchange of CO2 is electrochemically maintained within the basic and acidic ion exchange wafers by applying an electric potential across the cathode and anode.

  • Patent number: 6143556
    Abstract: The invention provides a process for gas separation wherein a selected gas in a mixed gas stream is contacted by an enzyme having an active site directly contacted by the mixed gas stream, and the selected gas is at least partially removed from the mixed gas stream. In one embodiment a selected gas in a gas phase is contacted by a solvated enzyme wherein the enzyme active site is in direct contact with the gas phase, and the selected gas is converted to a first product in a condensed phase by contact with the solvated enzyme.

  • Patent number: 5189064
    Abstract: Cocaine addiction is treated by administration of an endorphinase or enkephalinase inhibitor, and optionally, a dopamine precursor, or a serotonin precursor, a GABA precursor, or an endorphin or enkephalin releaser. These components promote restoration of normal neurotransmitter function and are non-addictive. Use of the dopamine precursors L-phenylalanine or L-tyrosine, the enkephalinase inhibitor D-phenylalanine and/or the serotonin precursor L-tryptophan is especially preferred.
