摘要： An ocean alkalinity enhancement (OAE) system that reduces atmospheric CO2 and mitigates ocean acidification by electrochemically processing feedstock solution (e.g., seawater or brine) to generate an alkalinity product that is then supplied to the ocean. The OAE system includes a base-generating device and a control circuit disposed within a modular system housing deployed near a salt feedstock. The base-generating device (e.g., a bipolar electrodialysis (BPED) system) generates a base substance that is then used to generate the ocean alkalinity product. The control circuit controls the base-generating device such that the alkalinity product is supplied to the ocean only when (1) sufficient low/zero-carbon electricity is available, (2) it is safe to operate the base-generating device, and (3) supplying the alkalinity product will not endanger sea life. Modified BPED systems include features that facilitate autonomous system operations including enhanced maintenance cycle operations and a reduced reliance on external fresh water sources.

摘要： An additively manufactured lattice includes a plurality of symmetrically oriented repeating unit cells. Each of the unit cells is comprised of a vertically oriented tubular structure having a top edge and bottom edge, said tubular structure defined by a circumferential side wall extending from said top edge to said bottom edge. The side wall has a lower portion, an intermediate portion, and an upper portion, with the lower portion terminating at the bottom edge, the upper portion terminating at the top edge, and the intermediate portion positioned between the lower portion and the upper portion. A plurality of spaced legs is included with each unit cell, with each leg formed as an outfolding of the side wall, each outfolding beginning at the side wall intermediate portion and extending progressively further outward through the side wall lower portion to the bottom edge.

摘要： Surface texturing of objects during additive manufacturing, including systems and methods thereof. For example, a method of surface texturing a three-dimensional (3D) object during additive manufacturing of the object: (a) irradiating a resin segment with patterned light at a build plane to polymerize said resin and grow said 3D object, then (b) advancing said object away from said build plane to bring a new segment of said resin in contact with said growing 3D object and establish a new build plane, and then repeating steps (a) through (b) until said 3D object is formed. For resin segments that correspond to portions of said 3D object to which surface texture is applied, said irradiating step is carried out by sequentially irradiating each resin segment with: (i) a first sub-exposure pattern and (ii) a second sub-exposure pattern, one of which is modified to include a texture pattern on a surface thereof.

摘要： A method of forming a three-dimensional object is carried out by: providing a carrier and a pool of immiscible liquid, the pool having a liquid build surface, the carrier and the liquid build surface defining a build region therebetween; filling the build region with a polymerizable liquid, wherein the immiscible liquid is immiscible with the polymerizable liquid (in some embodiments wherein the immiscible liquid has a density greater than the polymerizable liquid); irradiating the build region through at least a portion of the pool of immiscible liquid to form a solid polymer from the polymerizable liquid and advancing the carrier away from the liquid build surface to form the three-dimensional object comprised of the solid polymer from the polymerizable liquid. Optionally, but in some embodiments preferably, the method is carried out while also continuously maintaining a gradient of polymerization zone between the liquid build surface and the solid polymer and in contact with each thereof, the gradient of polymerization zone comprising the polymerizable liquid in partially cured form.
