A method including receiving a specimen comprising a carrier, a first target species, and a first component and storing at least a portion of the carrier and the first target species in a storage media by self-driven filtering of the specimen in the storage media, wherein the storage media comprises porous superabsorbent polymer (PSAP) beads. The PSAP beads provide for fast and self-driven microfiltration of biofluid samples. The treatment effectively separates small analytical targets (e.g., glucose, catalase, and bacteriophage) and large undesired components (e.g., bacteria and blood cells) in the biofluids by capturing the former inside and excluding the latter outside the PSAP beads. The treatment can reduce sample volume, self-aliquot the liquid sample, avoid microbial contamination, separate plasma from blood cells, stabilize target species inside the beads, and enable long-term storage at room temperature.

A sol-gel sorbent or chromatography stationary phase is a particulate metal oxide gel containing polymeric segments uniformly distributed throughout the metal oxide gel. The metal oxide gel is an oxide from silicone or other metal oxide that can have one of the valence bonds attached to an organic group and the remainder occupied by oxygens that can be provided as an oxide or an alkoxide or aryl oxide of the polymeric segments. The particles are used for an SPE sorbent or as a packing for a reversed phase high-performance liquid chromatography (RP-HPLC), a normal phase high-performance liquid chromatography (NP-HPLC) column or a hydrophilic interaction liquid chromatography (HILIC) column.

A method for enhancing filtration performance in separating solids from liquids in an aqueous dispersion comprising a solids phase and a liquid phase in a two-step process having a physical separation step and a filtration step comprising adding at least one filtration aid promoter and at least one synthetic polymer to the aqueous dispersion during and/or before the physical separation step resulting in a liquid-solid separation and filtering the liquid from the solid. The method may be applied in mining operations for the filtering of mining slurries.

The present invention achieves a moisture absorbing material which enables efficient dehumidification without supercooling or large heat quantity; and a dehumidifier in which the moisture absorbing material is used. The moisture absorbing material can be a dried product of a polymer gel in which an interpenetrating polymer network structure or a semi-interpenetrating polymer network structure is formed by (a) a stimuli-responsive polymer whose affinity with water changes reversibly in response to an external stimulus and (b) a hydrophilic polymer.

Provided herein is a porous β-cyclodextrin-containing monolith having a microstructure templated by the external phase of a HIPE, as well as processes of manufacturing the same and uses thereof.

An excrement-treating material has a core part, and a surface layer bonded to the core part by utilizing the adhesion ability of a water-absorbable polymer in the surface layer without using an adhesive. The excrement-treating material suitably exerts the water absorbability and water transport ability inherent to the surface layer. The excrement-treating material is constituted by incorporating pulverized water-absorbable polymer particles of 20 μm to 50 μm, and adding water to the surface of the core part after granulation to noncontinuously form a highly-wet part; reacting a water content in the highly-wet part and the pulverized water-absorbable polymer to noncontinuously form an adhering part; and bonding the surface layer to the core part through the adhering part. Upon absorption of excreted urine, permeation of the urine into the core part is accelerated in a part other than the adhering part.
