Disclosed herein are finished products, methods, compositions and kits for derivatizing plastic (e.g., “polymer”) surfaces in a manner that renders the surfaces appropriate for various downstream applications. For example, flow cells incorporating modified plastic surfaces provide greatly enhanced stability for retention of attached chemical species such as polypeptides and nucleic acids.

This invention relates generally to a process for selective adsorption and recovery of lithium from natural and synthetic brines, and more particular to a process for recovering lithium from a natural or synthetic brine solution by passing the brine solution through a lithium selective adsorbent in a continuous countercurrent adsorption and desorption circuit.

The invention relates to dispersions of porous solids in liquids selected from deep eutectic solvents, liquid oligomers, bulky liquids, liquid polymers, silicone oils, halogenated oils, paraffin oils or triglyceride oils, as well as to their methods of preparation. In embodiments of the invention, the porous solids are metal organic framework materials (MOFs), zeolites, covalent organic frameworks (COFs), porous inorganic materials, Mobil Compositions of Matter (MCMs) or a porous carbon. The invention also relates to the use of porous materials to form dispersions, and to assemblages of such dispersions with a gas or gases. The dispersions can exhibit high gas capacities and selectivities.

The present invention relates to a method for separating biomass from a solution comprising bi-omass and at least one aroma compound. comprising providing the solution comprising bio-mass and aroma compounds. lowering the pH value of the solution below 7 by adding at least one acid to the solution comprising biomass and the at least one aroma compound. adding an adsorbing agent to the solution comprising biomass and aroma compounds. and carrying out first membrane filtration so as to separate the biomass from the solution comprising the at least one aroma compound.

Devices for the separation of components within a fluid are disclosed herein. The device includes a housing that contains a roll of film with spaced apart microstructures thereon to crate channels to direct fluid flow. The channels have functionalized surfaces to attract and retain desired components in the fluid so that those components can be separated from the fluid. The film roll is typically contained by an outer sleeve around its perimeter to contain the fluid therein. The device also includes a central hub on which the film roll is mounted.

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.

An carbon molecular sieve for adsorbing water molecules in an alcohol solution to separate an alcohol from the water molecules, wherein the total volume of pores with an inlet diameter of 0.33 nm or more as determined by a molecular probe method is not less than 3 times the total volume of pores with an inlet diameter of 0.46 nm or more. This carbon molecular sieve is an alcohol concentration material that is capable of efficiently concentrating alcohol without performing a distillation step and that is easily reusable.
