Abstract: A method for obtaining aluminum-containing nanoparticles is provided. The method includes exposing at least one surface comprising aluminum to an alkaline aqueous solution. The method further includes exposing the at least one surface to electro-hydraulic shock waves and an electron flux. The at least one surface undergoes electro-erosion which creates alumina-hydrated nanoparticles having a negative surface electrical charge. The method further includes transforming the alumina-hydrated nanoparticles into aquachelate nanoparticles by attaching water molecules to the alumina-hydrated nanoparticles.

Abstract: A device and process are disclosed for the separate removal of oppositely charged ions from electrolyte solutions and recombining them to form new chemical compositions. The invention provides the ability to create multiple ion flow channels and then form new chemical compositions therefrom. The process is accomplished by selectively combining oppositely charged ions of choice from different electrolyte solutions via the capacitive behavior of high electrical capacitance electrodes confined in insulated containers.

Abstract: The solar fuels generator includes an ionically conductive separator between a gaseous first phase and a second phase. A photoanode uses one or more components of the first phase to generate cations during operation of the solar fuels generator. A cation conduit is positioned provides a pathway along which the cations travel from the photoanode to the separator. The separator conducts the cations. A second solid cation conduit conducts the cations from the separator to a photocathode.

Abstract: The method for manufacturing a photosemiconductor according to the present disclosure includes treating a metal base material containing at least one kind of transition metal with a plasma under a pressure lower than atmospheric pressure and at a temperature lower than a volatilization temperature of the transition metal under an atmosphere at the pressure to provide the photosemiconductor containing the transition metal and a nitrogen element from at least a part of the metal base material. Here, the plasma is generated by applying a high-frequency voltage at a frequency in a range of not less than 30 MHz and not more than 300 MHz to a gas between a first electrode and a second electrode, and the gas is any one of: (i) a nitrogen gas; (ii) a gaseous mixture consisting of a nitrogen gas and an oxygen gas; (iii) a gaseous mixture consisting of a nitrogen gas and a rare gas; and (iv) a gaseous mixture consisting of a nitrogen gas, an oxygen gas, and a rare gas.

Abstract: The present invention provides system, method and apparatus for creating an electric glow discharge that includes a first and second electrically conductive screens having substantially equidistant a gap between them, one or more insulators attached to the electrically conductive screens, and a non-conductive granular material disposed within the gap. The electric glow discharge is created whenever: (a) the first electrically conductive screen is connected to an electrical power source such that it is a cathode, the second electrically conductive screen is connected to the electrical power supply such that it is an anode, and the electrically conductive fluid is introduced into the gap, or (b) both electrically conductive screens are connected to the electrical power supply such they are the cathode, and the electrically conductive fluid is introduced between both electrically conductive screens and an external anode connected to the electrical power supply.

Abstract: An electrochemical device converts carbon dioxide to a formic acid reaction product. The device includes an anode and a cathode, each comprising a quantity of catalyst. The anode and cathode each have reactant introduced thereto. A cation exchange polymer electrolyte membrane and an anion exchange polymer electrolyte membrane, are interposed between the anode and the cathode, forming a central flow compartment where a carbon dioxide reduction product, such as formic acid, can be recovered. At least a portion of the cathode catalyst is directly exposed to gaseous carbon dioxide during electrolysis. The average current density at the membrane is at least 20 mA/cm2, measured as the area of the cathode gas diffusion layer that is covered by catalyst, and formate ion selectivity is at least 50% at a cell potential difference of 3.0 V.

Abstract: A thermal interface material (TIM) and method for manufacture is disclosed. A vertically aligned carbon nanotube (VACNT) array is formed on a substrate, then individual CNTs are cleaved to form a vertical nanoribbon array (VERNA). An array of aligned, upright, flat, highly-compliant ribbon elements permit a higher packing density, better ribbon-to-ribbon engagement factor, better contact with adjoining surfaces and potentially achievement of theoretical thermal conductance limit (˜1 GW/m2K) for such nanostructured polycyclic carbon materials. Methods for forming the VERNA include either or both of electrochemical and gas phase processing steps.

Abstract: A system to remove sodium and Sulfur from a feed stream containing alkali metal sulfides and polysulfides in addition to heavy metals. The system includes an electrolytic cell having an anolyte compartment housing an anode in contact with an anolyte. The anolyte includes alkali metal sulfides and polysulfides dissolved in a polar organic solvent. The anolyte includes heavy metal ions. A separator includes an ion conducting membrane and separates the anolyte compartment from a catholyte compartment that includes a cathode in contact with a catholyte. The catholyte includes an alkali ion-conductive liquid. A power source applies a voltage to the electrolytic cell high enough to reduce the alkali metal and oxidize Sulfur ions to allow recovery of the alkali metal and elemental sulfur. The ratio of sodium to Sulfur is such that the open circuit potential of the electrolytic cell is greater than about 2.3V.
