A method comprising reacting an aluminum mineral polymorph or a gallium mineral polymorph with an acid at an aluminum metal to acid molar ratio or gallium metal to acid molar ratio sufficient to produce Mnanoscale clusters, M nano-agglomerates, or a Mslurry, wherein M is Al or Ga.

Synthesis of M13 clusters from aluminum and gallium mineral polymorphs

A bipolar membrane comprising a first member comprising at least one anion exchange material; a second member comprising at least one cation exchange material, wherein the first member and the second member together form an interface junction; and disposed within the interface junction a first layer comprising a first water dissociation catalyst and a second layer comprising a second water dissociation catalyst, wherein the first water dissociation catalyst is different than the second water dissociation catalyst.

Bipolar membranes

Electrolytes for use in electric double-layer capacitors (EDLCs; often referred as supercapacitors or ultracapacitors) are disclosed. In one example, the electrolyte comprises viologen in both the anolyte and the catholyte (with bromide). In another example, the electrolyte comprises viologen (in the anolyte) and tetraalkylammonium with bromide (in the catholyte), wherein the tetraalkylammonium is used to achieve solid complexation of bromine in the activated carbon of the cathode. In a third example, a zinc bromine/tetraalkylammonium supercapacitor/battery hybrid is disclosed. Also disclosed is a corrosion resistant bipolar pouch cell that can be used with the electrolyte embodiments described herein.

Stable bromine charge storage in porous carbon electrodes using tetraalkylammonium bromides for reversible solid complexation

An electrical double layer capacitor (EDLC) energy storage device is provided that includes at least two electrodes and a redox-enhanced electrolyte including two redox couples such that there is a different one of the redox couples for each of the electrodes. When charged, the charge is stored in Faradaic reactions with the at least two redox couples in the electrolyte and in a double-layer capacitance of a porous carbon material that comprises at least one of the electrodes, and a self-discharge of the energy storage device is mitigated by at least one of electrostatic attraction, adsorption, physisorption, and chemisorption of a redox couple onto the porous carbon material.

Energy storage device including a redox-enhanced electrolyte

Three-dimensional patterning methods of a three-dimensional microstructure, such as a semiconductor wire array, are described, in conjunction with etching and/or deposition steps to pattern the three-dimensional microstructure.

Three-dimensional patterning methods and related devices

Disclosed herein are embodiments of methods for making GaAs thin films, such as photovoltaic GaAs thin films. The methods disclosed herein utilize sources, precursors, and reagents that do not produce (or require) toxic gas and that are readily available and relatively low in cost. In some embodiments, the methods are readily scalable for industrial applications and can provide GaAs thin films having properties that are at least comparable to or potentially superior to GaAs films obtained from conventional methods.

GaAs thin films and methods of making and using the same

A photoelectrode, methods of making and using, including systems for water-splitting are provided. The photoelectrode can be a semiconductive material having a photocatalyst such as nickel or nickel-molybdenum coated on the material.

Nickel-based electrocatalytic photoelectrodes

A structure comprising an array of semiconductor structures, an infill material between the semiconductor materials, and one or more light-trapping elements is described. Photoconverters and photoelectrochemical devices based on such structure also described.
