A process for recovery of lithium ions from a lithium-bearing brine includes contacting the lithium-bearing brine with a lithium ion sieve (where that LIS includes an oxide of titanium or niobium) in a first stirred reactor to form a lithium ion complex with the lithium ion sieve, and decomplexing the lithium ion from the lithium ion sieve in a second stirred reactor to form the lithium ion sieve and an acidic lithium salt eluate.

Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.

The present disclosure is related to a polymeric membrane, comprising a modified surface obtained from coating with hydrophilic monomers and curing the hydrophilic monomers with actinic irradiation, preferably UV light, wherein the hydrophilic monomers comprise at least one amino moiety; at least one polyoxyalkylene unit; and at least one (meth)acrylate moiety.

The present invention relates to a phytocomplex or natural concentrate rich in polyphenolic compounds such as hydroxytyrosol and 3,4-DHPA-EDA, derived from the waters from the pressing of olives for oil and/or olive pomace as residues of the olive milling process, for use in the reduction/attenuation of the symptoms and/or side effects associated with/caused by diabetes and/or the pathological conditions associated therewith.

A polymer film has a loofah-like structure. It has a fibrous framework structure formed by three-dimensional interwoven and interconnected polymer fibers and a three-dimensional interconnected network pore structure distributed in the fibrous framework structure. The polymer is an organic polymer and the fibrous framework structure is integrally formed by the polymer. The film has a volume porosity of from 50% to 95%. The film is obtained by means of a combination method for atomization pretreatment and non-solvent phase separation. The film can be used in the fields of gas filtration, liquid filtration, oil-water separation, adsorption materials, catalysis, pharmaceutical sustained release materials, anti-adhesion coatings, oil delivery and oil spill interception.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.

A method of obtaining a compound may include adding a substrate to a medium in a reactor, and reacting the substrate in the reactor to form the compound. A first stream is separated from the reaction liquid through a first membrane. A second stream is separated from the reaction liquid through a second membrane. The first membrane is a filtration membrane and the second membrane is configured for liquid-gas or liquid-liquid extraction The first membrane and the second membrane are at least partially immersed in the medium and are moved relative to the reactor during the separation steps.

The disclosure provides certain porous membranes comprised of cyclic polyolefin polymers, such as poly(norbornene)s. In one embodiment, a poly(norbornene) polymer is dissolved in tetrahydrofuran, cast into a film and subjected to solvent induced phase separation to provide a porous filter membrane (i.e., film).

The invention concerns an underwater water treatment unit which has specific cleaning means which are suitable for cleaning filtration membranes in the unconventional conditions associated with use at great or very great depths, as well as a method for cleaning the membrane of the underwater water treatment unit.
