A bi-directional air exchanger for a metal-air battery having a housing. The air exchanger includes an ambient air passageway for a first flow of air in a first direction, a battery exhaust passageway for a second flow of air in a second direction, and one or more membranes. The ambient air passageway and the battery exhaust passageway are separated within the housing by the one or more membranes such that the first and the second flows of air are in fluid communication with one another for the exchange of humidity.

A permeable membrane comprising a gas permeable substrate film and a layer of a polymeric perfluoro compound on the substrate exhibits selective transport of oxygen over water vapor and a metal-air electrochemical cell comprising such a membrane has enhanced control over its water content. Suitable polymeric perfluoro compounds include perfluoropolyalkylene oxides such as polyperfluoropropylene oxide or polyperfluoropropylene oxide co-perfluoroformaldehyde. The polymeric perfluoro compound layer is desirably crosslinked to form a thin layer on the substrate film or to form a self-supporting membrane. A suitable substrate film is a microporous polymer membrane.

A metal-air electrochemical cell comprising an oxygen reservoir disposed in an air plenum adjacent the air cathode. The oxygen reservoir includes an oxygen binding compound characterized in that the oxygen binding compound reversibly binds oxygen and releases oxygen into the air in the air plenum to power the cell when the partial pressure of oxygen in the air plenum drops due to a load on the cell.

There is disclosed a method of separating enantiomers of 4-(3',4'-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone comprising contacting the same with a homogeneous or nonhomogeneous liquid mixture of solvent and water, the mixture containing substantially pure and unsupported gamma-cyclodextrin or its derivatives. Also disclosed are methods of further enantiomerically enriching solid mixtures obtained from the enantiomer separation method and further extracting one enantiomer by solvent extraction of the solid mixtures obtained.

The present invention discloses a method for the enzymatic synthesis of a peptide. A protected peptide having a C-terminal carboxylate group or a protected, N-acyl amino acid having an alpha carboxylate group is reacted with a protected peptide having an N-terminal ammonium group or a protected amino acid having an alpha ammonium group in the presence of a condensation enzyme under conditions in which the carboxylate group and the ammonium group condense to form a protected, uncharged, peptide product. This peptide product is transported across a water-immiscible hydrophobic phase into an aqueous product phase and prevented from back diffusing across the water-immiscible hydrophobic phase. The peptide product can be converted, chemically or enzymatically, to a charged species that cannot back diffuse across the water-immiscible phase into the aqueous reaction phase. The water-immiscible hydrophobic phase is an ion rejection membrane separating the aqueous reaction phase from the product phase creating oil/water interfaces with each of the aqueous phases.

An improvement to processes for the selective extractation of organic solutes from organic solvents by water-based extractants is disclosed, the improvement comprising coupling various membrane separation processes with the organic extraction process, the membrane separation process being utilized to continuously recycle the water-based extractant and at the same time selectively remove or concentrate organic solute from the water-based extractant.
