A method for purifying a boron nitride nanotube feedstock is disclosed, including an initial step of mixing a boron nitride nanotube (BNNT) feedstock with a solvent to form an initial mixture. This BNNT feedstock is made up of hexagonal boron nitride (h-BN) particles and less than about 50 weight percent BNNTs on a dry basis. This initial mixture is then sonicated within a treatment vessel using an ultrasonic probe. At least a portion of the initial mixture is filtered out of the treatment vessel and across a nanoporous membrane at the same as the sonication. In this manner, the method provides a filtrate which is enriched in h-BN particles relative to the initial mixture and a retentate which is enriched in BNNTs relative to the initial mixture.

Described are liquid compositions that contain a desired (e.g., extracted) plant material such as cannabinoid, terpene, terpenoid, or the like, contained, e.g., dissolved, suspended, or emulsified, in the liquid, which contains surfactant; methods of preparing these types of liquid compositions; and methods of processing this type of liquid composition to collect, isolate, concentrate, or purify a desired target material contained in the liquid composition.

A method of recovering organic components from an aqueous biomass in the method includes: (i) providing an aqueous biomass containing organic components; (ii) treatment of the aqueous biomass to release intracellular organic components from within cells of the biomass to form a biomass suspension; addition of a water-immiscible component to the biomass suspension to form a mixture comprising biomass and water-immiscible component; (iv) subjecting the mixture comprising biomass and water-immiscible component to high shear to form a water-in-water-immiscible-component emulsion; and (v) separating the water-immiscible component phase from the water/aqueous phase.

Disclosed is a spreadable propolis products which can be used in many sectors such as food, health and cosmetics that offer them for human consumption in their most suitable and in the highest form of bioavailability, in a fast and easy consumable state by properly extracting propolis which cause development of antioxidant, antimicrobial, antifungal, antivirus, anti-inflammatory, anti-cancerogen and anesthesic effects as well as many beneficial biological activities. Production methods thereof are also disclosed.

Method of selective extraction of a metal of the family of platinoids, from a ceramic support containing said metal, comprising the following successive steps: a) said ceramic support containing said metal is brought into contact, in an extraction chamber, with an extraction medium consisting of a pressurized dense fluid containing an organic ligand that is selective for the metal and that is capable of forming a complex with said metal in the 0 state; whereby are obtained, on the one hand, a ceramic support depleted in said metal, or even free of said metal, and, on the other hand, a medium consisting of the pressurized dense fluid containing the complex of the organic ligand with the metal in the 0 state; b) said pressurized dense fluid containing the complex of the organic ligand with the metal in the 0 state is brought back to atmospheric pressure and to ambient temperature, whereby the complex of the organic ligand with the metal in the 0 state separates from the fluid; c) the ceramic support depleted in said metal, or even free of said metal, and the complex of the organic ligand with the metal in the 0 state, are recovered.

Methods of isolating phenols from phenol-containing media. The methods include combining a phospholipid-containing composition with the phenol-containing medium to generate a combined medium, incubating the combined medium to precipitate phenols in the combined medium and thereby form a phenol precipitate phase and a phenol-depleted phase, and separating the phenol precipitate phase and the phenol-depleted phase. The methods can further include extracting phenols from the separated phenol precipitate phase. The extracting can include mixing the separated phenol precipitate phase with an extraction solvent to solubilize in the extraction solvent at least a portion of the phenols originally present in the phenol precipitate phase.

The present invention relates to the field of upgrading biomass, in particular algal biomass, and more specifically the present invention relates to a method for extracting water-soluble compounds from microalgae and/or cyanobacteria, as well as the product obtained by this method and the uses of same, in particular in the food industry or as food supplements.

The present invention relates to a method of extracting a pigment from microalgae.

The present disclosure includes a nozzle and methods for using the nozzle in ways that may increase the efficiency of extraction of essential elements from plant matter. The nozzle may also be used to increase the efficiency of drying solvent saturated plant matter after an extraction has been completed. The nozzle may include an elongated tube with a plurality of holes that allow solvent and/or a gas to be provided or pumped/provided into an apparatus that includes plant matter. Nozzles consistent with the present disclosure may be optimized for extracting cannabis from cannabis plant matter or from other types of plants that include cannabinoids. In certain instances, nozzles may also be used when processing cannabinoid containing concentrates that were extracted from plant matter using any type of extraction technique.

The present disclosure broadly relates to a process for recovering scandium and/or vanadium values from various feedstocks. More specifically, but not exclusively, the present disclosure relates to a process for the selective recovery of scandium and/or vanadium values from a feedstock, the process comprising: leaching the feedstock in a sulfuric acid solution while simultaneously sonicating the sulfuric acid solution thereby producing a pregnant solution; and selectively removing scandium and vanadium compounds from the pregnant solution using a solvent extraction process.
