The present invention provides: a transparent desiccant for organic EL that is a cured product of an organopolysiloxane composition that contains (A) an alkenyl-group-containing organopolysiloxane including a linear organopolysiloxane having at least two alkenyl groups per molecule, (B) formula (I)

H.sub.aR.sub.bSiO.sub.(4-a-b)/2(I)

(in the formula, R is a C1-10 monovalent hydrocarbon group, a is 0.001-1.0, and b is 0.7-2.1), and (C) a hydrosilylation catalyst,
the number of mol Y of silicon-atom-bonded hydrogen atoms (mol) in component (B) satisfying the formula 0.002 (mol)(YX)0.8 (mol) relative to the number of mol X of silicon-atom-bonded alkenyl groups (mol) in component (A); and a method for using the transparent desiccant. The present invention can provide a transparent desiccant for organic EL that is highly transparent, is capable of top emission, has low shrinkage growth, suppresses loss of an element light-emitting portion, has an effect for suppressing the short-circuit phenomenon, and has exceptional defoaming properties in the material curing process.

The present invention relates to a method of controlling a defect structure in a chabazite (CHA) zeolite membrane, the CHA zeolite membrane having a controlled defect structure by the method and a method of separating CO.sub.2, H.sub.2, or He and water from a mixture of water and an organic solvent using the CHA zeolite membrane, and more particularly, to a method of controlling a defect structure in a CHA zeolite membrane that improves the separation performance by reducing the amount and size of defects formed in the CHA membrane structure when removing organic-structure-directing agents in the membrane through calcination at a low temperature using ozone.

The present disclosure relates to a preparing method of a super absorbent polymer sheet and a super absorbent polymer sheet prepared therefrom. The preparing method of a super absorbent polymer sheet of the present disclosure may prepare a porous flexible super absorbent polymer sheet exhibiting high flexibility and fast absorption rate.

The present invention relates to a method for purifying viruses or virus-like particles using a crosslinked cellulose hydrate membrane and to a kit for purifying viruses or virus-like particles and the use thereof.

Drug disposal devices and systems for reducing the amount of drug contained in a transdermal drug delivery patch are disclosed. The drug disposal devices contain an adsorbing substance, such as activated carbon, and are capable of adsorbing residual drug from the transdermal patch and preventing back-extraction of the drug. Also disclosed are methods of manufacturing the drug disposal devices and methods of using the drug disposal devices for reducing the amount of drug contained within a transdermal drug delivery patch.

A filtration membrane that includes a porous substrate layer and an active layer arranged over at least a part of the substrate layer. The active layer comprises a metal-organic framework (MOF). Also disclosed are methods for of producing a filtration membrane and uses of the filtration membrane for water treatment.

Solar energy device comprising at least one of a photovoltaic cell or a solar thermal collector having an absorption bandwidth in the infrared wavelength region of the solar spectrum; a visible light-transmitting reflector; and at least one of a graphic film or lighted display. The graphic film or a lighted display present is visible through the visible light-transmitting reflector. The solar energy devices can be used, for example, as a sign (e.g., an advertising sign or a traffic sign), on the side and/or roof, as well as in a window, of a building.

The present invention relates to porous films comprising (A) from 51 wt.-% to 99.9 wt.-% based on the total weight of the film of at least one porous metal-organic framework material, the material comprising at least one at least bidentate organic compound coordinated to at least one metal ion; (B) from 0.1 wt.-% to 49 wt.-% based on the total weight of the film of at least one fibrillated fluoropolymer; and (C) 0 wt.-% to 48.9 wt.-% based on the total weight of the film of an additive component. The invention further relates to a composition for preparing such a film and its use.

A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.

Embodiments of the present disclosure provide a metal-organic framework composition including a metal-organic framework having an ana topology, the metal-organic framework including one or more metals connected to one or more organic linkers. Embodiments of the present disclosure further provide a method of separating chemical species including contacting a metal-organic framework having an ana topology with a flow of paraffins and separating the paraffins.
