An odor sensor includes a base material, and a plurality of MOF particles arranged on the base material. In an XRD measurement for the plurality of MOF particles arranged on the base material, in a range of 2θ = 5 ° to 20 °, a peak intensity of a third highest peak is ⅒ or less with respect to a peak intensity of a first highest peak.

A magnetic soil remediation agent for soil heavy metal pollution and a preparation method and application thereof are provided. The magnetic soil remediation agent is prepared by using remediation agent framework material and magnetic core material as raw materials, and heavy metal collector as modifier; said framework material is silicon dioxide activated by strong alkali; said magnetic core material comprises magnetic materials Fe.sub.3O.sub.4 and γ-Fe.sub.2O.sub.3; said modifier comprises ethylenediaminetetraacetic acid (EDTA, nitrilotriacetic acid trisodium salt (NTA, (S,S)-ethylenediamine-N,N-disuccinic acid trisodium salt (EDDS) and mercaptoethylamine. The remediation agent of the present invention can effectively passivate the heavy metals in the soil, reduce their available contents, and inhibit the absorption of heavy metals by plants.

A separation membrane structure comprises a porous support, a first separation membrane formed on the porous support, and a second separation membrane formed on the first separation membrane. The first separation membrane has an average pore diameter of greater than or equal to 0.32 nm and less than or equal to 0.44 nm. The second separation membrane includes addition of at least one of a metal cation or a metal complex that tends to adsorb nitrogen in comparison to methane.

A novel system for the analysis of molecules and cells, comprising clusters where a non-magnetic particle is supplemented with magnetic particles to form a characteristic pattern, fingerprint or bar code. Methods and devices for formation of such particles are also disclosed.

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 invention relates to alkenyl(perfluoroalkyl)phosphinic acids, to the preparation and intermediates thereof, to the use thereof as monomers for the preparation of oligomers and/or polymers, to the corresponding oligomers/polymers, to the corresponding support materials comprising the oligomers/polymers, and to the use thereof as ion exchangers, as catalysts or extraction medium and corresponding salts thereof.

A process includes removing air bubbles from extracorporeal blood via chemical entrapment of nitrogen (N.sub.2) gas.

A method of producing a functionalized material that extracts metal ions from solution, the method comprising: (i) providing a precursor material having nitrile groups appended to its surface; and (ii) reacting said nitrile groups with hydroxylamine or a derivative thereof in the presence of a polar aprotic solvent at a temperature of 60-80° C. for at least 1 hour, to convert at least a portion of said nitrile groups to amidoxime and imide dioxime groups, followed by reaction with a base capable of hydrolyzing any remaining nitrile groups to carboxylic acid groups; wherein said functionalized material has a higher uranium absorption capacity than a functionalized material produced under same conditions except that the nitrile groups are reacted with hydroxylamine in only a protic solvent. The invention is also directed to functionalized materials produced by the above-described method, and methods for using the functionalized material for extracting metal ions from metal-containing solutions.
