Compositions for bromide removal include a two-dimensional material impregnated with silver. The silver may be impregnated in the two-dimensional material by contacting the two-dimensional material with silver ions in an aqueous solution, allowing the silver ions to adsorb on the two-dimensional material, and drying the two-dimensional material. Removing bromide from an aqueous composition including bromide may include contacting the aqueous composition with a two-dimensional material impregnated with silver, and allowing the bromide to react with the silver to yield silver bromide.

The invention also relates to a product, comprising an agent for modulating metastatic tumor cell dissemination, and to a method of treatment or prevention of cancer.

The present invention relates to a method to improve chromatography beads. More closely, the invention relates to a novel method for production of dextran-containing porous media and chromatography media produced with this method. In the method, the chromatography media is subjected to dextranase-treatment leading to improved pressure-flow properties of the media.

Coated iron oxide (10) nanocrystal structures, superparamagnetic 10 nanoparticles, methods for synthesizing coated 10 nanocrystal structures, and methods for synthesizing superparamagnetic 10 nanoparticles are described herein. A coated 10 nanocrystal structure may comprise an iron oxide core, a manganese ferrite shell layer surrounding the core, and a bilayer coating surrounding the shell layer. The bilayer coating may include an inner oleic acid layer surrounding the shell layer and an outer layer surrounding the inner oleic acid layer.

The present invention relates to a surface modified zeolite adsorbent wherein the surface of said zeolite is modified with a coating comprised of a silicone derived species, said zeolite having a mean crystal size from about 5 to about 10 ?m and a skeletal density of ?1.10 gr./cc. The invention is based on the discovery that larger crystals tend to have higher particle density, and the packing of the larger crystals in agglomeration processes leads to more idealized packing to provide a larger mean-pore diameter. The surface modified adsorbent provides rate selectivity for one gas over others is described. The superior adsorbent has the added convenience of bead forming simultaneously with pore modification as well as having the treatment result in the yielding of high crush strength products.

An adsorption device for compressed gas, is provided with a vessel with an inlet for the supply of a compressed gas to be treated, and an outlet for treated gas and an adsorption element is affixed in the vessel. The adsorption element extends along the flow direction of the compressed gas to be treated, between the inlet and the outlet. The adsorption element has a monolithic supporting structure that is at least partially provided with a coating that contains an adsorbent.

The present disclosure relates to a method of synthesizing composites for removing heavy metals, including: preparing hollow hydroxyapatite particles including a functional group; preparing a composite in which magnetic oxide nanoparticles are combined on the hollow hydroxyapatite; and preparing a composite of hollow hydroxyapatite and metal particles by performing reduction annealing to the composite.

A method for manufacturing an adsorption agent for treating compressed gas, which includes the steps of providing a monolithic supporting structure; producing a coating suspension that includes an adsorbent; applying the coating suspension on the supporting structure to form a coating; applying a thermal treatment to the coated supporting structure in order to sinter the coating.

The present invention provides a novel method to fabricate silica nanostructures on thin polymer films based on silica deposition and self-wrinkling induced by thermal shrinkage. These micro- and nano-scale structures have vastly enlarged the specific area of silica, thus the silica nanomembranes can be used for solid phase extraction of nucleic acids. The inventive silica nanomembranes are suitable for nucleic acid purification and isolation and demonstrated better performance than commercial particles in terms of DNA recovery yield and integrity. In addition, the silica nanomembranes have extremely high nucleic acid capacity due to its significantly enlarged specific surface area of silica. Methods of use and devices comprising the silica nanomembranes are also provided.

The present disclosure relates to a process for capturing carbon-dioxide from a gas stream. In order to capture the carbon-dioxide, a support is provided and potassium carbonate (K.sub.2CO.sub.3) is impregnated thereon to form an adsorbent comprising potassium carbonate (K.sub.2CO.sub.3) impregnated support. The adsorbent is activated to form an activated adsorbent. The gas stream is passed through the adsorber to enable adsorption of the carbon-dioxide on the activated adsorbent to form a carbon-dioxide laden adsorbent. The carbon-dioxide laden adsorbent is transferred to a desorber for at least partially desorbing the carbon-dioxide from the carbon-dioxide laden adsorbent by passing a carbon-dioxide deficient stream through the desorber. The partially regenerated adsorbent is returned to the adsorber for adsorbing the carbon-dioxide from the carbon-dioxide. The process of the present disclosure reduces the overall energy demand by partially regenerating the adsorbent.
