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.

The invention relates to an apparatus (1) for catalytic decomposition of nitrous oxide in a gas stream derived from exhalation air from a patient. The apparatus (1) comprises an inlet arrangement (2) with a gas inlet (3) for the exhalation air, an outlet arrangement (11) with a gas outlet (12) for an outlet gas, and between these arrangements a through-flow decomposition chamber (9) containing a catalyst material. According to the invention the apparatus is provided with a nitrous oxide adsorption/desorption means (4) in the inlet arrangement (2) for level out variations in the concentration of nitrous oxide fed to the decomposition chamber (9).

The present invention relates to the isolation and amplification of odors so that the underlying odorous material might be located. The present invention utilizes a triple layer odor absorbent sampling media, solvents, and a heat source to isolate and amplify the odors. Once the source of the odor is located, the odorous material can then be cleaned.

A filter and a method for removing aldehyde-type VOCs from indoor air are disclosed. The filter includes a casing acting as a container. The container comprises two air-permeable opposite walls through which a volume of said indoor air flows and houses one or more natural polyphenols and a catalytic agent. The filter acts as an absorption filter, reacting irreversibly with the aldehyde-type VOCs of the indoor air. The natural polyphenols are powdered polyphenols selected from resveratrol (3,4′,5-trihydroxystilbene), resorcinol (1,3-benzenediol), pyrogallol (1,2,3-benzenetriol), phloroglucinol (1,3,5-benzenetriol) and hydroquinone (1,4-benzenediol), or combinations thereof. The catalytic agent is a solid sulfonic acid. A mixture of the natural polyphenols and said catalytic agent are present, in the container, as compacted block elements. An air-purifying/decontaminating device comprising the filter is also disclosed.

Smoking article include a smokable material and an activated carbon particle downstream of the smokable material. The activated carbon particle is produced from a whole seed. The activated carbon particle has a length, width and height. At least two of the length width and height are independently in a range from about 1 mm to about 7.5 mm. The particles can be spheroids, in which case the length, width and height would be the same or similar.
