Abstract: 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.

Abstract: A fluid delivery device has a syringe barrel-type reservoir with plunger, and plunger driver assembly comprising double-acting, telescoping lead screws that is located behind and outside of the barrel. Simultaneously and counter-rotating sleeve screw and center screw telescope out of a nested configuration of the plunger driver assembly and into the reservoir at a rate of double their individual and equal pitch and lead parameters when the sleeve screw is rotated. A threaded nut and gear anchor disposed on an end of the barrel receive the sleeve screw and the threaded nut causes the sleeve screw to translate and rotate in response to motor operation. A distal end of the center screw can be keyed to a plunger pusher for anti-rotation constraint when the motor is imparting rotation on the threaded nut and sleeve screw.

Abstract: A gas turbine engine includes a containment ring to contain liberated compressor and turbine blades and blade fragments within a core assembly. The combination of a containment gap between the core case and the containment ring and a containment layer disposed in the gap helps dissipate the energy generated by loose body impacts on the core assembly. The containment layer deforms, deflects, and/or redirects the impact energy acting in a radial direction, thereby to improve containment.
