A sulfur adsorbent comprising boric acid deposited on an activated carbon support, and a method of separating at least a portion of sulfur compounds from a sulfur-containing mixture with the sulfur adsorbent. Various combinations of embodiments of the sulfur adsorbent and the method are also provided.

The present invention relates to a method for preparing superabsorbent polymer with improved anti-caking, and according to the present invention, a method for preparing superabsorbent polymer that has properties equivalent to or more excellent than the existing superabsorbent polymer but has improved anti-caking, and thus, has excellent processability, and superabsorbent polymer prepared thereby, are provided.

An object of the present disclosure is to provide an NO.sub.x storage material having sufficient NO.sub.x storage capacity even in a low temperature region and a production method thereof.

An NO.sub.x storage material including a composite oxide of silver and gallium. The composite oxide of silver and gallium is preferably a delafossite-type composite oxide. The composite oxide is produced by dissolving a silver salt and a gallium salt in a solvent and baking the solution, wherein the molar ratio of silver:gallium is preferably from 2:8 to 7:3.

The present invention relates to a superabsorbent polymer which exhibits more improved liquid permeability while maintaining excellent absorption performance, and suppresses aggregation and caking of particles even under high temperature/high humidity conditions, and to a method for producing the same. The super absorbent polymer comprises: a base polymer powder including a first crosslinked polymer of a water-soluble ethylenically unsaturated monomer having at least partially neutralized acidic groups; and a surface crosslinked layer formed on the base polymer powder and including a second cross-linked polymer in which the first cross-linked polymer is further crosslinked via a surface cross-linking agent, wherein the super absorbent polymer includes aluminum sulfate dispersed in the surface crosslinked layer and alumina dispersed on the surface crosslinked layer.

Methods for synthesizing macroscale 3D heteroatom-doped carbon nanotube materials (such as boron doped carbon nanotube materials) and compositions thereof. Macroscopic quantities of three-dimensionally networked heteroatom-doped carbon nanotube materials are directly grown using an aerosol-assisted chemical vapor deposition method. The porous heteroatom-doped carbon nanotube material is created by doping of heteroatoms (such as boron) in the nanotube lattice during growth, which influences the creation of elbow joints and branching of nanotubes leading, to the three dimensional super-structure. The super-hydrophobic heteroatom-doped carbon nanotube sponge is strongly oleophilic and can soak up large quantities of organic solvents and oil. The trapped oil can be burnt off and the heteroatom-doped carbon nanotube material can be used repeatedly as an oil removal scaffold. Optionally, the heteroatom-doped carbon nanotubes in the heteroatom-doped carbon nanotube materials can be welded to form one or more macroscale 3D carbon nanotubes.

A method of determining opal-C and cristobalite contents of a product that comprises diatomite is disclosed. The method may comprise performing thermal processing to determine a loss on ignition for a representative first portion of a sample of the product; identifying and quantifying primary and secondary peaks present in a first diffraction pattern that results from bulk powder X-ray Diffraction on a representative second portion of the sample; and using a known standard sample of cristobalite to determine whether the primary and secondary peaks present in the first diffraction pattern indicate the presence of opal-C or cristobalite in the product.

A composition that absorbs oxygen and emits carbon dioxide in response to absorbing oxygen including ascorbic acid, an organic acid, a catalyst that promotes oxidation of the organic acid and emission of carbon dioxide and a soluble transition metal salt characterized by multiple oxidation states.
