    Abstract: A system for separating at least one constituent from a liquid suspension such as blood induces high velocity flow by viscous drag about the circumference of a spinner having a filtration membrane with pore size selected for the desired constituent. The high velocity circumferential flow is bounded by a spaced apart shear wall, with a spacing selected relative to the diameter of the spinner and its rotational velocity, also with respect to the viscosity of the suspension, to establish a flow within the shear gap, as substantial centrifugal forces are exerted upon the suspension. Under these conditions, filtrate in contact with the membrane is replenished, and filtrate passes through the membrane with minimal adverse effects from deposition and concentration polarization, and with high efficiency because of high shear levels that are maintained. The filtrate is collected within the interior of the spinner in a conduit system and passed to an outlet orifice.

    Abstract: A cross-flow electrochemical cell for producing electricity is disclosed that incorporates means for cross-flow pumping of electrolyte through both anode and cathode electrodes in the same direction to achieve markedly higher discharging and charging currents. Cross-flow pumping enabling use of thick mesh electrodes comprising scaffolds impregnated with high-surface-area metal nanoparticles and having high porosity are also taught.
