The compositions and methods that can be used in desiccants in manufactured units requiring an enclosed atmosphere with minimal water and volatile content. Such materials need to maintain a low concentration of volatile materials in an enclosed space in a unit to avoid any unneeded interference of water or other volatiles in the utility of the unit. In one application, the desiccant material can keep the insulated glass units (IGUs) from fogging, which includes forming water or depositing volatiles on internal surfaces.

The present disclosure provides a multilayer article. The multilayer article includes a) a microfiltration membrane substrate; b) a first layer directly attached to the first major surface of the microfiltration membrane substrate; and c) a second layer directly attached to the first layer.

Embodiments of the present invention are directed to a porous monolith polymeric composition having utility in catalysis, chromatography, filtration, and electro-kinetic pumps, devices incorporating such composition and methods or making and using such monoliths. The monoliths are characterized by a substantially homogeneous skeletal core with little shrinkage, few voids and few channels.

The present invention relates to a method for the preparation of polymer shells, preferably composed of cellulose or hemicellulose, comprising the steps of dissolving the polymer component in a first solvent, preferably an organic solvent and precipitating the polymer component by contacting the first solution with a second solvent, which second solvent has a polar character, and in which second solvent the polymer component is essentially insoluble, thereby obtaining polymer shells. Moreover, the invention refers to the polymer shells as such, having permeable and responsive properties, as well as various applications comprising such polymer shells within the fields of drug delivery, separation techniques, and inter alia filling material.

Disclosed herein are embodiments of a polymer-functionalized particle for using in isolating and extracting solutes, such as rare earth metals, lithium, and the like. The polymer-functionalized particles exhibit strong resistance to agglomeration and degradation even in high ionic strength and/or temperature environments. A post-particle synthesis method for making the polymer-functionalized particle is disclosed, along with a magnetic separation device and that can be used in system embodiments to facilitate use and regeneration of the polymer-functionalized particles in solute extraction.

A cationic composite filter aid may include a silicate substrate, a silica precipitated on the silicate substrate, and a cationic surface modification of the precipitated silica. A method for making a cationic composite filter aid may include providing a silicate substrate, precipitating a silica onto the silicate substrate to form a composite filter aid, and cationically modifying the precipitated silica to form a cationic composite filter aid. A method for filtering a liquid may include providing a liquid for filtering and filtering the liquid through a cationically modified composite filter aid. The cationically modified composite filter aid may include a silicate substrate, a precipitated silica, and a cationic surface modification of the precipitated silica.

A separation device includes a first shredding unit, a first beating unit, and a first separation unit. The first shredding unit shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second material) adhering to the plastic. The first beating unit beats the disposable diaper shredded by the first shredding unit with a first beating member, thereby promoting dissociation of the water-absorbent polymer from the plastic. The first separation unit rotates a first tubular portion in a state in which the disposable diaper beaten by the first beating unit is accommodated therein, thereby separating the water-absorbent polymer passing through first holes from the disposable diaper.

Provided are a sheet for pets which contains carbon and has a superior appearance, and a method of manufacturing the sheet for pets. A sheet for pets is provided with a liquid-permeable front surface sheet, a liquid-impermeable back surface sheet, an absorbent layer that contains carbon and is positioned between the front surface sheet and the back surface sheet, and a front surface-side liquid-permeable sheet that is black and is positioned on the front surface sheet-side of the absorbent layer. The front surface-side liquid-permeable sheet is preferably formed from pulp fibers that have been dyed black.
