摘要： The present disclosure belongs to the technical field of porous membrane material preparation, and specifically relates to a reverse osmosis composite membrane with an ultrathin desalting layer and a preparation method thereof; the intermediate layer is introduced after modifying the polysulfone base membrane, the modified polysulfone base membrane support layer may strengthen the bonding to the desalting layer through a covalent bond, and the thickness of the desalting layer is reduced to be ≤10 nm, so that the desalination rate of the membrane is not greatly affected while increasing the membrane flux. Compared with the membrane having a conventional thickness of the desalting layer, the water flux of the reverse osmosis composite membrane with an ultrathin desalting layer may be increased by about 0.5 times, while the desalination rate has a small change.

摘要： An appliance includes a housing defining an interior cabinet, a crisper drawer disposed therein, and a circulation system. The crisper drawer includes a base, walls, and lid defining a cavity, the lid selectively closing the drawer to limit air flow to and from the cavity. One or more of the base, the walls, and the lid define an opening for a humidity membrane disposed therein, sealed in the opening. The membrane includes nanofibers dispersed in a matrix to provide pervaporation across the membrane for airflow from the cavity to the interior cabinet. The circulation system cooperates with the membrane, and includes one or more fans disposed within the drawer to selectively facilitate air flow across the membrane and mix air within the cavity to control a humidity level within the drawer.

摘要： A thin-film composite membrane may comprise a mixed-matrix membrane supported by a substrate, the mixed-matrix membrane comprising two or more sublayers. At least one of the sublayers may comprise 10 by weight (wt %) to 75 wt % filler particles and 25 wt % to 90 wt % polymer. A method of making a thin-film composite membrane may include performing an electrospraying cycle, comprising electrospraying a first solution onto a surface of a substrate, the solution comprising a first solvent and filler particles, the substrate being positioned on a support surface; electrospraying a second solution onto the surface of the substrate, the second solution comprising a second solvent and a polymer; and after electrospraying a predetermined number of cycles, removing the substrate from the support surface.

摘要： This disclosure provides systems and methods for direct production of lithium hydroxide by utilizing cation selective, monovalent selective, or preferably lithium selective membranes. Lithium selective membranes possess high lithium selectivity over multivalent and other monovalent ions and thus prevent magnesium precipitation during electrodialysis (ED) and also address the presence of sodium in most naturally occurring brine or mineral based lithium production processes.

摘要： A CO2 separation membrane can include a CO2-philic layer comprising one or more mobile CO2 carriers and one or more immobile CO2 carriers and a blended CO2-permeable and CO2-selective matrix that hosts the immobile or mobile CO2 carriers and porous nanostructures that adsorb water vapors. The CO2-philic layer can be disposed upstream of the CO2-permeance layer such that a flow of source gas to be separate enters the membrane from a feed side at which the CO2-philic layer is present and CO2 exits the membrane at a permeate side after passing through both the CO2-philic layer and the CO2-permeance layer.
