Disclosed herein are a superabsorbent polymer resin incorporated with a particles meeting the following properties i) to ii): i) a BET specific surface area of 300 to 1500 m.sup.2/g, ii) a porosity of 50% or more, and a method for preparing the same.

A high-temperature open-cell porous body, the body comprises crystalline inorganic particles and 0.5 to 3-weight percent glass. The crystalline inorganic particles are bonded together by the glass to form a matrix with interconnected pores having a porosity of greater than 20-percent. The crystalline inorganic particles may further include interconnected micro pores, the latter combination providing a matrix with both macro porosity and micro porosity.

A ceramic membrane, and a process for producing a ceramic membrane. In the process for the production of a ceramic membrane the ceramic membrane is produced by additive manufacturing. The ceramic membrane comprises a membrane portion comprising pores. A nano-and/or micro-particle is formed in-situ from a nano- and/or micro-particle precursor during the additive manufacturing process and/or post-processing step. The ceramic membrane comprises the in-situ formed nano- and/or micro-particle, or residue thereof, arranged within the pores of the membrane portion. Also described is a water treatment module including the ceramic membrane.

The present disclosure provides for sorbents, methods of using sorbents and contactors to capture CO.sub.2, structures including the sorbent, and systems and devices using sorbents to capture CO.sub.2. The methods, systems, contactors, and sorbents of the present disclosure can be advantageous since they are robust and reduce the cost of capturing CO.sub.2, in particular from ambient air. The present disclosure provides for sorbents having a support and a CO.sub.2-philic phase that includes phosphite containing molecules, which leads to a sorbent that is effective for capturing CO.sub.2.

A method for producing a polyamide medium for purifying a protein-containing solution, comprising: a step of treating a polyamide medium before a treatment with an acidic or alkaline aqueous solution, with an acidic or alkaline aqueous solution.

Porous solid amine adsorbents are prepared by bringing into contact a first (e.g., dope) solution, including a water insoluble polymer and a water-soluble amine polymer, with an aqueous solution containing a multifunctional chemical agent. The first solution can be obtained by dissolving the water insoluble polymer and the water-soluble amine polymer in a polar solvent. The adsorbents can be in the form of beads, sheets, fibers, hollow fibers, etc. and can be used in the removal of acid gases, CO.sub.2, for instance, from fluid streams.

Provided herein are adsorption materials comprising a metal-organic framework comprising metal ions of metals, a plurality of organic linkers and one or more modulator where each modulator forms a localized defect. Each organic linker in the plurality of organic linkers creates a bridge between metal ions. Each modulator is connected to only one metal chain. The adsorption material further comprises one or more ligands. Each ligand in the plurality of ligands can be an amine or other Lewis base (electron donor) appended to a metal ion of the metal-organic framework.
