Abstract: A solution flows through a salinate chamber and a desalinate chamber of an electrochemical cell. Solutes are moved from the desalinate chamber to the salinate chamber to create respective solvent and concentrate streams from the desalinate and salinate chambers. The concentrate stream flows to a recombination cell where it is combined with a solvent. The combination causes at least one of an absorption of heat within the recombination cell and emission of heat from the recombination cell.

Abstract: Air flows across an air-liquid interface such that liquid desiccant flowing through the interface absorbs water from the air and is thereby diluted to form an output stream. The output stream is circulated through an electrodialytic stack having a central ionic exchange membrane and first and second outer ionic exchange membranes. A redox shuttle loop circulates around the first and second outer ionic exchange membranes. A voltage is applied across the electrodialytic stack, which regenerates the liquid desiccant.

Abstract: A method and apparatus are described for forming a multilayer assembly. The method includes adhering first and second catalyst layers to opposed sides of a polymer membrane. At least one of the first catalyst layer, the second catalyst layer, and the polymer membrane is formed by filament extension atomization of a fluid material to form atomized droplets that are sprayed to form the respective membrane or layer.

Abstract: A system comprises an electrodialysis apparatus, which includes first and second reservoirs, wherein a salt concentration in the first reservoir reduces below a threshold concentration and salt concentration in the second reservoir increases during an operation mode. A first electrode comprises a first solution of a first redox-active electrolyte material, and a second electrode comprises a second solution of a second redox-active electrolyte material. In a first reversible redox reaction between the first electrode and first electrolyte material at least one ion is accepted from the first reservoir, and in a second reversible redox reaction between the second electrode and second electrolyte material at least one ion is driven into the second reservoir. A first type of membrane is disposed between the first and second reservoirs, and a second type of membrane, different from the first type, is disposed between the respective electrodes and reservoirs.

Abstract: A method of transferring a semiconductor epi layer onto a metal host substrate is described. An epi layer of a semiconductor chip (e.g., semiconductor laser array) including a substrate can be mounted onto a planar handle wafer with an adhesive, wherein a backside of the substrate faces upward and away from the epi layer and the planar handle wafer. The backside of the substrate can be treated to substantially remove the substrate, while leaving the epi layer undamaged (e.g., by polishing to where no more than 20 micrometers of the substrate remains). Metal can be formed on the treated backside resulting in a metalized backside. The planar handle wafer can then be removed from the epi layer by dissolving the adhesive with a solvent, wherein a modified semiconductor chip remains. The semiconductor chip can be annealed to form a backside ohmic contact interface. The semiconductor chip can then be attached to a mechanical block by the ohmic contact interface.

Abstract: A polymer electrolyte membrane includes an ion-conducting polymeric electrolyte material and platelets, distributed through the polymeric electrolyte material. The platelets have an aspect ratio of length to thickness of at least 2:1. The platelets are aligned generally parallel to a length of the membrane. The platelets can be functionalized with free radical scavengers, or other moieties, to extend the lifetime of the membrane or of a membrane electrode assembly incorporating the membrane.
