Embodiments describe a method of depositing an MOF, including depositing a metal solution onto a substrate, spinning the substrate sufficient to spread the metal solution, depositing an organic ligand solution onto the substrate and spinning the substrate sufficient to spread the organic ligand solution and form a MOF layer.

The present invention relates to the use, for affinity purification of an antibody or an fragment of an antibody, of a ligand-substituted matrix comprising a support material and at least one ligand covalently bonded to the support material, the ligand being represented by formula (I)
L-(Sp).sub.v-Ar.sup.1—Am—Ar.sup.2   (I)
wherein L, SP, Ar.sup.1, AM, Ar.sup.2 and v are defined herein.

An excrement-treating material has a core part, and a surface layer bonded to the core part by utilizing the adhesion ability of a water-absorbable polymer in the surface layer without using an adhesive. The excrement-treating material suitably exerts the water absorbability and water transport ability inherent to the surface layer. The excrement-treating material is constituted by incorporating pulverized water-absorbable polymer particles of 20 μm to 50 μm, and adding water to the surface of the core part after granulation to noncontinuously form a highly-wet part; reacting a water content in the highly-wet part and the pulverized water-absorbable polymer to noncontinuously form an adhering part; and bonding the surface layer to the core part through the adhering part. Upon absorption of excreted urine, permeation of the urine into the core part is accelerated in a part other than the adhering part.

A polymeric hybrid particle or composition comprising of polymers, such as polystyrene or methylated polystyrenes with cyclic amines and their halogenated forms, and nanoparticles (NPs). The method for the preparation thereof and uses as nano-adsorbent, or a biocide, or a dual function combination of biocide and adsorbent for use in a fluid system for the purpose of purification or remediation are also disclosed.

The invention concerns biocompatible polymer systems comprising at least one polymer with a plurality of pores, said polymer comprising either polyol or zwitterionic groups designed to adsorb endotoxins and other inflammatory mediator molecules. The inventions are in the field of porous polymeric sorbents, also in the field of broadly reducing endotoxins in blood and blood products that can cause endotoxemia, additionally, in the field of broadly removing endotoxins by perfusion or hemoperfusion.

Disclosed is an improved process for recovering condensable components from a gas stream, in particular, hydrocarbons from a gas stream such as natural gas. The present process uses solid adsorbent media to remove said hydrocarbons wherein the adsorbent media is regenerated in a continuous fashion in a heated continuous counter-current regeneration system, wherein said heated regenerated adsorbent media is cooled prior to reuse.

Articles are provided for absorbing fluids. In embodiments, the articles of the present disclosure are modified to make them hydrophobic, thereby decreasing their affinity for water and similar liquids, while increasing their affinity for other hydrophobic materials, including oil. After use, the articles, in embodiments sponges, may have their absorbed materials removed therefrom, and the articles may then be re-used to absorb additional materials.
