Methods and systems for deposition of blended polymer films are disclosed. According to an aspect a method of producing a film on a substrate includes combining a guest material, a host matrix, and a solvent having one or more hydroxyl (O—H) bonds to form a target emulsion. The method also includes exposing the target emulsion to an infrared source that is tuned to an absorption peak in the host matrix that is reduced in or absent from the guest material thereby desorbing the host matrix from the target emulsion and lifting the guest material from the surface of the target emulsion. The target emulsion and the substrate are oriented with respect to each other such that the lifted guest material is deposited as a film upon the substrate.

Methods for preparing all-aqueous emulsions, including stable emulsions or emulsions having high viscosity and/or ultra-low interfacial tension are described. The method includes mixing, combining, or contacting a first electrically charged phase containing a first solute (e.g., dispersed phase) with at least a second phase containing a second solute (e.g., continuous phase). The solutes are incompatible with each other. The electrostatic forces between the two phases induce the formation of droplets of a dispersed phase in a continuous phase. The dispersed and continuous phases contain oppositely charged molecules, such as surfactants or other macromolecules and colloids which stabilize the drops of the dispersed phase. Complex coacervation of the oppositely charged molecules or colloids at the interface of the two aqueous phases results in formation of a membrane or barrier which prevents coalescence or aggregation of the droplets. The membrane also prevents leakage of any encapsulated agents from the droplets.

The present disclosure relates to a system and method for treating wastewater, the method comprising the steps of: providing a vessel for receiving wastewater and a gas, wherein the gas comprises one or more constituent gas components; directing the wastewater and a first gas component of the gas to the vessel; reducing the temperature of the contents of the vessel from a first temperature to a second temperature to facilitate the formation of clathrate hydrates comprising the wastewater and the first gas component; increasing the temperature of the contents of the vessel with respect to the second temperature to facilitate melting of the clathrate hydrates; and removing clean water and/or the first gas component from the vessel.

Microbubble production and size isolation with high yield processing. Specifically, a size isolation process is used in which a diffusion coefficient related to gas diffusion forces acting on microbubbles in suspension is controlled through maintaining diffusion parameters for the suspension. Diffusion parameters may include effective viscosity, which may be a function of microbubble volume fraction. Another diffusion parameter controlled may include temperature. In turn, microbubbles may be size isolated at high yields, which may provide for advantageous microbubble products that demonstrate increased stability for storage.

A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.
