An organic light emitting display device may include a filling part filling a space between a second substrate and an organic light emitting diode, and a dam structure disposed in a non-display area and surrounding the filling part. At least one of the dam structure and the filling part includes a getter. The getter of the present disclosure is composed of magnesium oxide particles whose surfaces are modified into a first surface modification part made of an amino silane-based compound and a second surface modification part bound to the first surface modification part and made of a compound containing an acrylate group and a methacrylate group. Accordingly, it is possible to provide an organic light emitting display device that has high transparency and of which optical properties and durability are improved by minimizing permeation of water and oxygen.

A method for extracting and enriching gold with a selenide includes: mixing an isocyanate and a selenium-containing compound of a formula of HO—R—Se—R—OH in a solvent to obtain a mixture system, where R is selected from linear or branched C.sub.2 to C.sub.11 alkylene groups; adding a tin-based catalyst into the mixture system to activate a reaction, drying the mixture system after the reaction, and obtaining a powdery selenium-containing polymer by grinding; immersing the selenium-containing polymer in an aqueous solution containing gold ions to allow gold to be extracted from the aqueous solution; and removing the selenium-containing polymer attached to a surface of extracted gold, thereby obtaining an extracted and enriched gold.

Novel crystalline porous materials known as metal-organic frameworks (MOFs) and methods for their synthesis are provided herein. The MOFs include a M.sub.6(μ.sub.3-OH).sub.8(OH).sub.8(μ.sup.2,η.sup.2-(O.sub.2C).sub.2cyclam).sub.8 cluster, and a metal atom coordinated to the one or more cyclam of the cluster, wherein M is Zr or Hf, and the metal atom is any one of Cu, Ni, Cr, Ru, Co, and Gd. The MOFs can be used as an adsorbent, alone or in a medium with other components, of CO.sub.2. The MOFs can also be used as a catalyst for the transformation of CO.sub.2 and epoxides to cyclic carbonates. The MOFs can also be used in the electrochemical catalytic reduction of CO.sub.2. The MOFs can also be used for photocatalytic CO.sub.2 reduction for the production of carbon-based fossil fuels. The MOFs can also be used for light-induced nitric oxide (NO) release. The MOFs can also be used as magnetic resonance imaging (MRI) agents.

A method of sorbing a PFAS compound from a contaminated environment can include admixing a modified clay sorbent with the environment. The modified clay can include a clay intercalated with a blend of mono-quaternary amine compound and di-quaternary amine compound.

The present disclosure relates to non-hemolytic adsorbent compositions useful for isolating, enumerating, accounting, and removing the disease-causing toxic constituents in the blood. The said compositions are useful in identifying the disease, disease status, and validating the efficacy of the therapeutic treatment being administered for the treatment of the disease. Methods for isolating, enumerating, accounting, and removing disease-causing toxic constituents in the blood as well as monitoring the disease status and validating the efficacy of the therapeutic treatment being administered for the treatment of the disease are disclosed.

Solid absorbent compositions and methods for the removal of mercaptan sulfur compounds from hydrocarbon streams are provided. The compositions may include porous granulated activated carbon particles with internal pore surfaces containing bound trinuclear basic iron (III) acetate complex containing the [Fe.sub.3(.sup.3-O)] core structure.
