A porous sorbent ceramic product includes a three-dimensional structure having an electrically conductive ceramic material, wherein the conductive ceramic material has an open cell structure with a plurality of intra-material pores, a sorbent additive primarily present in the intra-material pores of the conductive ceramic material for adsorption of a gas, and at least two electrodes in electrical communication with the conductive ceramic material.

A crosslinked polymer that is in the form of a Mannich polycondensation product including reacted units of a cyclic diaminoalkane, an aldehyde, and bisphenol-S or melamine. Also disclosed is a method for removing heavy metals from an aqueous solution by contacting the aqueous solution having an initial concentration of the heavy metal with the crosslinked polymer to form a mixture, and filtering the mixture to obtain an aqueous solution having a reduced concentration of the heavy metal compared to the initial concentration.

An adsorbate-selective metal organic framework includes a transition metal; and a plurality of organic molecules coordinated to the transition metal so as to preserve open coordination sites for selectively adsorbing molecules that have low-lying π* orbitals. The transition metal has a lowest energy spin state in the presence of the selectively adsorbed molecules that are strongly bonding to the transition metal through π-donating interactions which is different than the lowest energy spin state in the absence of these adsorbed molecules. The transition metal has also a lowest energy spin state in the presence of non-selected molecules that are weakly bonding to the transition metal through σ- and/or π-accepting and/or donating interactions.

The present invention is directed to a method, device and system to capture carbon dioxide in air using solid amine sorbents and using a radio frequency and/or microwave generator to desorb the carbon dioxide by directly exciting the amine-carbon bond thereby significantly reducing the energy cost of releasing the carbon dioxide.

The present invention provides a lectin-magnetic carrier coupling complex for separating glycosylated exosomes from a clinical sample. The lectin-magnetic carrier coupling complex comprises a magnetic carrier and lectins coupled to the outer side of the magnetic carrier. The lectin-magnetic carrier coupling complex provided by the present invention may rapidly, accurately, and automatically separate glycosylated exosomes from a clinical sample with a high separation efficiency; and the separated exosomes are intact in morphology without rupturing or cracking, may be directly used for liquid detection of glycosylated exosomes, or directly used for immunology-related detection, or directly used for nucleotide sequence detection and analysis after extracting nucleic acids from the exosomes.

The disclosure relates to modified wood pulp and methods using the same for removal for per- and polyfluoroalkyl substances (collectively “PFAS”) from contaminated water. Cationic-modified wood pulp can be used to adsorb anionic PFAS contaminants from water, and anionic-modified wood pulp can be used to adsorb cationic PFAS contaminants from water. The modified wood pulp has high adsorption efficiencies, rapid adsorption kinetics, and high adsorption efficiencies for a range of different PFAS contaminants.

A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.

A method and apparatus for removing an organosilicon component from a mixture are disclosed. The method and apparatus employ a copolymer of a di-alkenyl functional aromatic hydrocarbon and a polyorganosiloxane as the sorbent.

The present disclosure relates to molecularly imprinted polymers that target cannabinoid(s), including THC and CBD, as well as methods of making molecularly imprinted polymers that target cannabinoid(s), including THC and CBD and uses thereof.

Provided is a system and method for extracting organic solutes from water with a filter media. The system and method allow for regenerating the filter media following treatment of a water supply containing one or more organic solutes to allow the media to be reused for subsequent water treatment operations. The system and method also allows for regeneration of the displacement fluid for reuse in the regeneration of the media with recovery of at least one or more organic solutes from the displacement fluid. Additionally, the system and method allows for substantially continuous treatment of a water supply and regeneration of a filter media.
