A method and a system for in-situ remediation of recalcitrant organic and inorganic contaminants in an environmental medium are disclosed. Dissolved gases from water and an oil are removed to form degassed water and a degassed oil. The degassed water and the degassed oil are mixed to form a surfactant-free oil-in water emulsion. The surfactant-free oil-in-water emulsion is injected into the environmental medium, thereby producing anaerobic conditions to cause indigenous anerobic bacteria to biodegrade residual concentrations of the contaminants in the environmental medium.

Sometimes, a problem is obvious, everyone sees it, but nothing happens until someone decides to do something useful about it. Methods are herein provided for recovering heavy hydrocarbons from plastic materials and/or geo-formation. In one solution set, PVC waste materials are emulsified by an amine solvent in an aqueous phase, thereby extracting heavier hydrocarbons from the primary structure of PVC into the amine aqueous phase; followed by de-emulsifying the extracted heavier hydrocarbons by separating and recovering the amine solvent, and then separating the de-emulsified heavier hydrocarbons from the aqueous phase by a hydrophobic membrane.

Provided herein is a method for preparing microcarrier particles, comprising the steps of allowing the dispersed phase liquid flow through a multi-hole plate at a low temperature to form liquid microspheres in a continuous phase, and enabling a synthetic polymer and/or natural biological macromolecules within the liquid microspheres to be subject to a curing reaction at a low temperature to form particles. Further provided herein are the method for preparing an emulsion and an apparatus and process system for preparing microcarrier particles, which can be used for preparing emulsions and microcarrier particles on a large scale.

The present disclosure provides a method for preparing biopolymer particles, said method comprising a membrane emulsification of a dispersed phase into a continuous phase wherein the dispersed phase comprises the biopolymer in a solvent, and wherein passing the dispersed phase through the membrane forms an emulsion of the biopolymer in the continuous phase; and a phase inversion with an anti-solvent to form particles of the biopolymer; wherein prior to (b), the emulsion is cooled to a temperature, T1. Also provided are biopolymer particles obtained from the method.

[PROBLEMS] To provide a multistage apparatus used in a liquid-liquid system comprising two liquid phases that do not mix with each other, in which the position of the interface (liquid-liquid interface) of a heavy liquid phase and a light liquid does not fluctuate or else is suppressed, and a method of producing a specific substance using it. [SOLVING MEANS] An apparatus having a connected body of a plurality of adjacent containers or two or more stages installed in a single-piece container in which a plurality of partitions are arranged inside thereof, and a method of producing a specific substance using it. The multistage extraction is performed so as that the position of the interface (liquid-liquid interface) of a heavy liquid phase and a light liquid does not fluctuate or else is suppressed, by using the mechanism in which only the heavy liquid phase communicates in the lower part of the container, the mechanism in which only the light liquid phase communicates in the upper part of the container, or both of them.

A highly stable cannabinoid nanoparticle carrier composition for administration to a human made by incorporating non-ionic surfactants with cannabinoid oils and lipids, sonicating for a predetermined period of time at a predetermined amplification with an ultrasonic liquid processor until completely integrated; combining the mixture with a carrier fluid that includes ascorbic acid and distilled water; and further sonicating the mixture using an ultrasonic liquid processor at predetermined amplitude for a predetermined period of time at a controlled temperature, and thereby to create a CBD nanoemulsion. The composition is tailored using non-ionic surfactants to adsorb to the surface of the cannabinoid oil particles to advantageously affect electrokinetics and surface forces at the interface of the bioactive cannabinoid particles and the suspending liquid are controlled by tailoring the suspending liquid to maximize the zeta potential.
