Zeolites for extraction of heavy metals are given enhanced purification in a first method stage and further processed in a second method stage to form liquid and solid phases including swollen clinoptilolite fragments ranging from 200 to 2000 Daltons and formed as liposomes and usable to substantially reduce heavy metal ppm burdens for purposes of safe ingestion by mammals and reduction of heavy metal contaminants of gut, vascular and lymphatic systems of a mammalian host.

The invention discloses a sound-absorbing material particle and a preparation method thereof. The method for preparing the sound-absorbing material particle comprises: mixing a sound-absorbing raw material with a solvent to form a sound-absorbing slurry; filling the sound-absorbing slurry into a mechanical compression die, and performing compression molding on the sound-absorbing slurry to form a particle; performing a hydrothermal crystallization reaction on the particle to crystallize the sound-absorbing raw material in the particle; and drying the particle to produce the sound-absorbing material particle.

A faujasite-type zeolite has an IR spectrum in which the IR spectrum has an absorption band 1 including surface silanol groups and having a local maximum in a range from 3730 cm.sup.−1 to 3760 cm.sup.−1, and an absorption band 2 including acidic hydroxyl groups and having a local maximum in a range from 3550 cm.sup.−1 to 3700 cm.sup.−1, a ratio (h1/h2) of a peak height (h1) of the absorption band 1 to a peak height (h2) of the absorption band 2 being less than 1.2.

Disclosed herein are modified zeolites and methods for making modified zeolites. In one or more embodiments disclosed herein, a modified zeolite may include a microporous framework comprising a plurality of micropores having diameters of less than or equal to 2 nm. The microporous framework may include at least silicon atoms and oxygen atoms. The modified zeolite may further include organometallic moieties each bonded to bridging oxygen atoms. The organometallic moieties may include a titanium atom. The titanium atom may be bonded to a bridging oxygen atom, and the bridging oxygen atom may bridge the titanium atom of the organometallic moiety and a silicon atom of the microporous framework.

The present disclosure is directed to a method for making a MER framework type zeolite, a MER framework type zeolite having a stick-like morphology, and processes for the selective separation of carbon dioxide (CO.sub.2) from multi-component feedstreams containing CO.sub.2 using the zeolite.

A secondary growth procedure described herein is used to prepare finned zeolites. The finned zeolites possess properties that are distinctly unique compared to crystals of similar size lacking fins. The procedure is amenable to a wide range of zeolite crystal structures.

A separation system includes first and second separation parts each having a separation membrane and provided with a fluid supply port, a permeate fluid exhaust port, and a non-permeate fluid exhaust port, an intermediate connecting part for connecting the permeate fluid exhaust port of the first separation part and the fluid supply port of the second separation part, a supply pipe connected to the fluid supply port of the first separation part, in which a mixed fluid flows at a pressure higher than an atmospheric pressure, and a pressure reducing part connected to the permeate fluid exhaust port of the second separation part, for reducing a pressure inside the permeate fluid exhaust port to a pressure lower than the atmospheric pressure. A pressure inside the intermediate connecting part is lower than a pressure inside the supply pipe and not lower than the atmospheric pressure.

Provide is a functional structural body that can suppress aggregation of metal oxide nanoparticles and prevent functional loss of metal oxide nanoparticles, and thus exhibit a stable function over a long period of time. A functional structural body (1) includes: a skeletal body (10) of a porous structure composed of a zeolite-type compound; and at least one type of metal oxide nanoparticles (20) containing a perovskite-type oxide present in the skeletal body (10), the skeletal body (10) having channels (11) that connect with each other, and the metal oxide nanoparticles (20) being present at least in the channels (11) of the skeletal body (10).
