A method to form a phase change material (PCM). The method includes preparing a polymer solution by mixing an amount of a polymer in a solvent and mixing the polymer solution with an UiO-66 metal-organic framework (MOF) to form a composite. The polymer is a polyethylene glycol (PEG). The method further includes subjecting the composite to ultrasonic agitation and evaporating the solvent from the composite to form the PCM. After the evaporation of the solvent, particles of the PCM exhibit rounded octahedral structures.

Methods of preparing and using a metal-organic framework (MOF) are provided herein, including methods of using an MOF comprising a repeat unit of the formula [ML].sub.n, wherein M is a divalent metal ion and L is a ligand of the formula: ##STR00001##
The MOFs provided herein may be used in the separation of two or more molecules from each other. In some embodiments, the molecules are ethylene and ethane. In some embodiments, UTSA-280 may be synthesized from calcium oxide (CaO) or calcium hydroxide (Ca(OH).sub.2) and squaric acid (SA) through mechanochemical synthesis.

Disclosed herein are embodiments of sensor devices comprising a sensing component able to determine the presence of, detect, and/or quantify detectable species in a variety of environments and applications. The sensing components disclosed herein can comprise MOF materials, plasmonic nanomaterials, redox-active molecules, a metal, or any combinations thereof. In some exemplary embodiments, optical properties of the plasmonic nanomaterials and/or the redox-active molecules combined with MOF materials can be monitored directly to detect analyte species through their impact on external conditions surrounding the material or as a result of charge transfer to and from the plasmonic nanomaterial and/or the redox-active molecule as a result of interactions with the MOF material.

The present invention relates, inter alia, to the use of porous crystalline solids constituted of a metal-organic framework (MOF) for the selective adsorption of aldehyde volatile organic compounds.

The MOF solids of the present invention can be used for the improved purification of dry or humid air, and for the manufacture of regenerable filters for air purification, particularly leak-free regenerable air filters.

Sorptive gas separators can employ contactors having various sorbents blended together. The various sorbents used to make a blended sorbent contactor can be selected for their various physical and chemical properties, which will allow operators to customize formulations and structural configurations to obtain optimum performance of sorptive gas separators using blended sorbents.

Disclosed are embodiments of a cabin filter system including a sorbent material for removing gas and/or water from a cabin. The filter system also includes at least one heater configured to transmit thermal energy (e.g., microwave energy) to the sorbent material. Also disclosed are methods of using such filter systems.

Methods making a metal-organic framework extrudate in an extruder comprising the steps of: (a) mixing a metal-organic framework material with an extrusion aid to form a metal-organic framework extrudate mixture; and (b) extruding the metal-organic framework mixture in the extruder to produce the metal-organic framework extrudate where the pressure within the extruder is reduced between about 10% to about 55% when compared to pressure within the extruder when extruding the metal-organic framework material without the extrusion aid. The extrusion aid can be a liquid extrusion aid, a solid extrusion aid and/or a polymeric extrusion aid.

Disclosed herein is a polycrystalline metal-organic framework membrane comprising a substrate material having a surface and a polycrystalline metal-organic framework attached to the surface of the substrate material, wherein the polycrystalline metal-organic framework is formed from a secondary building unit having the formula Ia or IIb and a ligand as defined in the application.

Embodiments provide a method of compound removal from a fluid. The method includes contacting one or more metal organic framework (MOF) compositions with a fluid and sorbing one or more compounds, such as CO.sub.2, H.sub.2S and condensable hydrocarbons. One or more of CO.sub.2, H.sub.2S and condensable hydrocarbons can be sorbed simultaneously or in series. The metal organic framework can be an M-soc-MOF.

The invention relates to dispersions of porous solids in liquids selected from deep eutectic solvents, liquid oligomers, bulky liquids, liquid polymers, silicone oils, halogenated oils, paraffin oils or triglyceride oils, as well as to their methods of preparation. In embodiments of the invention, the porous solids are metal organic framework materials (MOFs), zeolites, covalent organic frameworks (COFs), porous inorganic materials, Mobil Compositions of Matter (MCMs) or a porous carbon. The invention also relates to the use of porous materials to form dispersions, and to assemblages of such dispersions with a gas or gases. The dispersions can exhibit high gas capacities and selectivities.
