Abstract: The direct solar desalination system with enhanced desalination has a main chamber having a slanted transparent top and vertical sidewalls. Saltwater is fed to the top of a series of plates, with the top plate and every other plate slanting into the chamber, while the intervening plates slant back toward the chamber wall. The lower edge of the plates that are slanted into the chamber have a plurality of copper channels or wires extending between the plate's edge and the opposite chamber wall. Saltwater that does not flow down the channels/wires drips down to the next plate and so forth, and any remaining saltwater is collected at the bottom of the chamber. The channels/wires are coated with a photothermal layer to enhance evaporation. The fresh water condenses on the bottom surface of the slanted top, flows down the surface, and is collected at the bottom of the shortest sidewall.

Abstract: Systems and methods for the controlled release of a guest composition that is sequestered within a host composition made up of an anisotropic fluid are disclosed. The guest composition is immiscible in the host composition, thus forming an interface between the compositions upon which elastic repulsion forces act to prevent the release of the guest composition from the host composition. The disclosed systems and methods work by changing the elastic repulsion forces and/or introducing one or more counter forces such that the elastic repulsion forces are no longer sufficient to prevent release of the guest composition. Exemplary methods include mechanically changing the host material (e.g., changing its temperature) or inducing a chemical (e.g., electrostatic) attraction sufficient to overcome the elastic repulsion forces. The disclosed systems and methods can be used for a variety of applications requiring “on-demand” delivery of a chemical composition.

Abstract: A stabilized, gas-infused liquids containing ultra high concentrations of infused gas, produced by: generating a gas-infused liquid in a sealed vessel under a high pressure of at least 20 psi; stabilizing the gas-infused liquid by passing the liquid while still under the high pressure through a tubular flow path arrangement which compresses the infused gas into nano bubbles in the liquid; infusing an additional amount of the gas into the stabilized liquid by injecting the same, while still under high pressure, back into the sealed pressure vessel along with more of the gas; and again stabilizing the liquid by again passing liquid, while still under the high pressure, through the tubular flow path arrangement to thereby form the additional amount of infused gas into nano bubbles in the liquid.
