摘要： Electrochemical reactors with electrodes that have variable porosity across the electrode and associated methods are described. The electrodes are designed and micro-architected to have variable porosity and 3D flow. One example method of selecting porosities in an electrochemical reactor includes dividing an electrode of the electrochemical reactor into a plurality of unit cells and determining a plurality of cell-specific porosities for the plurality of unit cells as a function of a location for each of the plurality of unit cells. The cell-specific porosities are configured based on a rod diameter of each unit cell's internal structure relative to each unit cell's cell length, and each location in the electrode provides a selected fluid flow property and a selected conductive property to meet one or more performance metrics.

摘要： Disclosed are electrochemical reactors with electrodes that have variable porosity across the electrode. The electrodes are designed and micro-architected to have variable porosity and 3D flow. In one aspect, an electrochemical cell apparatus is disclosed. The apparatus includes an electrochemical vessel and an electrochemical fluid contained in the electrochemical vessel. The apparatus further includes a porous electrode submerged in the electrochemical fluid in the electrochemical vessel, the porous electrode having different porosities in different areas of the porous electrode. The different porosities inhibit electrochemical fluid flow and increase electrical conductivity in first areas of the porous electrode with decreased porosity compared to second areas, and enable increased electrochemical fluid flow and decrease electrical conductivity in the second areas of the porous electrode with increased porosity compared to the first areas.

摘要： An ink for three dimensional printing a ceramic material includes metal oxide nanoparticles and a polymer resin, where a concentration of the metal oxide nanoparticles is at least about 50 wt % of a total mass of the ink. A method of forming a porous ceramic material includes obtaining an ink, where the ink comprises a mixture of metal oxide nanoparticles and a polymer, forming a body from the ink, curing the formed body, heating the formed body for removing the polymer and for forming a porous ceramic material from the metal oxide nanoparticles. The forming the body includes an additive manufacturing process with the ink.

摘要： A method of forming a magnet includes forming a structure by electrophoretic deposition (EPD), and after forming the structure, sintering the formed structure to form a magnet. The forming the structure by EPD includes adding a plurality of first particles having magnetic anisotropy to an EPD chamber and applying a voltage differential across electrodes of the EPD chamber to create an electric field in the EPD chamber for causing electrophoretic deposition of the first particles above a first of the electrodes for forming a first layer comprising the first particles.
