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.

Abstract: A roller includes a cylindrical outer surface of a hydrophobic material, an inner core of a hydrophilic material, and an inhomogeneous geometric pattern of grooves in the surface that expose the hydrophilic material. A method of manufacturing a roller, includes providing a cylindrical core of a hydrophilic material, covering the cylindrical core with a hydrophobic surface, creating grooves in the hydrophobic surface to form a geometrically inhomogeneous pattern of the hydrophilic material. A method of manufacturing a roller, includes forming a pattern of geometrically inhomogeneous grooves on a hydrophobic core, functionalizing the surface to make the surface hydrophilic, and removing a portion of a top layer of the hydrophobic core to expose the hydrophobic core, leaving hydrophilic grooves.

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: 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 system includes an electrodialysis device with a salinate chamber through which a salinate stream flows. A desalinate chamber is separated from the salinate chamber by a central, ion-selective membrane. A desalinate stream flows through the desalinate chamber. An anolyte chamber and a catholyte chamber are on opposite outer sides of the salinate and desalinate chambers and separated therefrom by first and second ionic exchange membranes. A solvent exchange interface is in contact on a first side with the salinate stream and is in contact a media flow on a second side. The solvent exchange interface moves a solvent from the media flow to the salinate stream.

Abstract: A method of storing digital data in non-biological sequence-controlled polymers includes converting a digital data file into a monomer sequence, synthesizing polymer chains according to the monomer sequence, and encapsulating the polymer chains into microfluidic droplets and providing the microfluidic droplets with addresses. A polymer data storage system has a first converter to convert digital data to a polymer sequence, a polymer synthesizer to produce polymer chains according to a pre-determined monomer sequence, a fluidic encapsulation system to encapsulate the polymer chains in microfluidic droplets and to apply addressing materials to the microfluidic droplets, a storage for storing the microfluidic droplets, a droplet sorting system having at least an actuator to sort the droplets, a sequencer to derive the polymer sequence from the polymer chains contained in the droplets, and a second converter to convert the polymer sequence to digital data. A composition of matter wherein polymer chains comprising alternating segments of flexible linkers and one or more rigid monomer blocks, and wherein the rigid blocks are defined in a meaningful manner to store in a sequence in the polymer chain that represents digital data.
