A method of removing contaminants from a solution comprises passing a solution including one or more contaminants through a first cell comprising a first anode chamber and a first cathode chamber, passing a slurry comprising a flowing electrode material through the first anode chamber and the first cathode chamber while applying an electric potential between the first anode chamber and the first cathode chamber to transport anions from the solution to the first anode chamber and to transport cations from the solution to the first cathode chamber, the flowing electrode material comprising a MXene material, wherein M is a metal and X is one or both of carbon and nitrogen, and passing the slurry through a second cell to desorb the anions and cations from the flowing electrode material. Related systems for removing contaminants from a solution, and related methods are disclosed.

A sensor for passively measuring a maximum temperature within a nuclear reactor comprises a substrate, and a plurality of melt wires within a cavity defined within the substrate, at least one melt wire of the plurality of melt wires exhibiting a variable melting temperature along a length of the at least one melt wire. Related sensors and methods of forming the sensors are also disclosed.

Methods for manufacturing an electrochemical sensor include forming at least one electrode by printing at least one conductive ink on a surface of at least one substrate. The conductive ink may comprise, e.g., a platinum-group metal, another transition-group metal with a high-temperature melting point, a conductive ceramic material, glass-like carbon, or a combination thereof. The electrochemical sensor may be free of another material over the at least one electrode. An electrochemical sensor, formed according to such methods, may be configured for use in harsh environments (e.g., a molten salt environment). Electrodes of the electrochemical sensor comprise conductive material formed from a printed, conductive ink. In some embodiments, at least a portion of the electrochemical sensor is free of silver, gold, copper, silicon, and polymer materials, such portion being that which is to be exposed to the harsh environment during use of the electrochemical sensor.

Water-based nanoparticle inks may be formulated to be compatible with printed electronic direct-write methods. The water-based nanoparticle inks may include a functional material (nanoparticle) in combination with an appropriate solvent system. A method may include dispersing nanoparticles in a solvent and printing a circuit in an aerosol jet process or plasma jet process.

Aqueous based nanoparticle ink

A device may include a flexible substrate. The device may further include a flexible integrated circuit within the flexible substrate, the integrated circuit having at least one input electrode positioned on a surface of the flexible substrate. The device may also include an aerosol jet printed conductive ink layer disposed on the surface of the flexible substrate, the aerosol-jet printed conductive ink layer having a pattern that includes a first set of fingers interdigitated with a second set of fingers, the aerosol jet printed conductive ink layer in contact with the at least one input electrode.
