A zirconium metal-organic framework, which is a coordination product formed between zirconium ion clusters and a linker that links together adjacent zirconium ion clusters, wherein the linker is of formula (I) ##STR00001##
wherein R.sup.1 is hydrogen or an optionally substituted alkyl, and R.sup.2 to R.sup.4 are independently hydrogen, an optionally substituted alkyl, an optionally substituted aryl, or an optionally substituted arylalkyl. A method of capturing CO.sub.2 from a gas mixture with the zirconium metal-organic framework.

The disclosed subject matter relates to a microcapsule including a particle core selected from activated carbon (AC), super activated carbon (SAC), MOF composition, multifunctional material or a mixture thereof and a water-soluble polymer shell, including a membrane into which the microcapsule is incorporated, a membrane with exposed AC, SAC, MOF, or multifunctional materials or mixture thereof formed therefrom and methods used is the formation of all of the above.

Embodiments of the present disclosure include a metal-organic framework (MOF) composition comprising one or more metal ions, a plurality of organic ligands, and a solvent, wherein the one or more metal ions associate with the plurality of organic ligands sufficient to form a MOF with kag topology. Embodiments of the present disclosure further include a method of making a MOF composition comprising contacting one or more metal ions with a plurality of organic ligands in the presence of a solvent, sufficient to form a MOF with kag topology, wherein the solvent comprises water only. Embodiments of the present disclosure also describe a method of capturing chemical species from a fluid composition comprising contacting a MOF composition with kag topology and pore size of about 3.4 Å to 4.8 Å with a fluid composition comprising two or more chemical species and capturing one or more captured chemical species from the fluid composition.

Method for making a Zn MOF of formula Zn.sub.2Ht.sub.2CL, where Ht is 1,2,4-triazolate or a combination of 1,2,4-triazolate and one or more other cycloazocarbyl compound, and CL is oxalate or a combination of oxalate and one or more chelating ligand other than oxalate. More specifically, the Zn MOF is Zn.sub.2Tz.sub.2Ox, where Tz is 1,2,4-triazolate and Ox is oxalate. The method includes reacting 2 molar equivalents of 1,2,4-triazole or the combination with cycloazocarbyl compound with 1 molar equivalent of oxalate or the combination with other chelating ligand and adding 2 molar equivalents of Zn.sup.2+ to form the Zn MOF. The solvent used can be a lower alcohol or a miscible mixture of water and a lower alcohol. One or both reaction steps are conducted at a temperature less than or equal to 120° C. and can be conducted at room temperature and ambient pressure.

A detoxification method includes the steps of inducing flow of patient blood through an extracorporeal device inlet and outlet in fluid connection to the circulatory system of a patient. Biological agents including lipopolysaccharide (LPS) contained within patient blood can be detoxified by passing patient blood over a biochemical reactor surface having attached or immobilized Saccharomyces boulardii alkaline phosphatase enzyme, with the biochemical reactor being contained within the extracorporeal device. An acyloxyacyl hydrolase enzyme may also be used on the biochemical reactor surface.

The invention generally relates to a process for purifying a hydrogen gas for use in a fuel cell. The process involves taking a hydrogen feed stream from a high-pressure tank and passing it through a purifier comprising an adsorbent to provide a purified hydrogen stream which is sent to a fuel cell. A particular adsorbent which can be used is a metal-organic framework composition. The adsorbent can be housed in a device such as a canister or cartridge having an inlet and outlet port.

A water collecting apparatus (100) includes a moisture-absorbing material (10) and a heat-conducting member (20). The moisture-absorbing material (10) includes a polymer compound having a property in which a degree of hydrophilicity changes with temperature. The heat-conducting member (20) is disposed facing a portion of an outer surface of the moisture-absorbing material (10) and has thermal conductivity.
