摘要： A material is provided for capturing a chemical substance comprising fibers which carry metal alkoxide particles on the surfaces thereof. The metal alkoxide particles are made from an oligosilica, an oligozirconia, an oligotitiania, or the like. The fibers may include inorganic fibers, regenerated fibers and/or synthetic fibers. The material for capturing a chemical substance is produced by a method comprising steps of subjecting the fibers to a surface treatment for facilitating adhesion of the metal alkoxide particles to the surfaces of the fibers, forming the metal alkoxide particles on the surfaces of the fibers, and fixing the metal alkoxide particles to the surfaces of the fibers. A chemical substance-capturing tube, capable of capturing a trace of a chemical substance in a liquid or a gas, can be produced by placing the fibers, i.e., the material for capturing a chemical substance, in a hollow tube.

摘要： A new shaped activated carbon and the method of its manufacture are disclosed. The invention resides in the crosslinking of a polymeric cellulose, such as sodium carboxymethylcellulose (CMC), within the carbon bodies after they are shaped, employing the CMC as a binder for the activated carbon. The approach to attain product mechanical strength and water stability by crosslinking rather than high temperature heat treatment is not obvious from the prior art teaching. The crosslinking reaction occurs at temperatures below 270null C. In addition, this new binder technology produces shaped carbon bodies having key properties beyond the best level that has been accomplished with other binders.

摘要： Nonporous beads having an average diameter of about 0.5-100 microns are suitable for chromatographic separation of mixtures of polynucleotides when the beads comprise a nonporous particle which are coated with a polymer or which have substantially all surface substrate groups endcapped with a non-polar hydrocarbon or substituted hydrocarbon group. The beads provide efficient separation of polynucleotides using Matched Ion Polynucleotide Chromatography.

摘要： Porous zirconia or zirconium-containing particles, methods of making such particles and methods of using such particles including modifications to the surface of the particles are described. The method comprises heating zirconia particles to provide a substantially homogeneously liquid melt, quenching the particles of melt to effect spinodal decomposition to provide quench particles of a silica rich phase and a zirconia rich phase, annealing the quenched particles to provide non porous solid particles of zirconia and silica and, leaching the silica from these particles to produce porous solid zirconia particles comprising a three dimensionally substantially continuous inter penetrating network of interconnected pores.

摘要： The invention relates to specific sorbents based on hydrophylic polymeric gels, preferably of a macroporous character, which carry covalently bonded D-aminoacid or peptide which contain D-aminoacid units. The basic carrier prepared by copolymerization of hydroxyalkyl esters or hydroxyalkylamides of acrylic and methacrylic acid with crosslinking acrylate or methacrylate comonomers are modified by the reaction with diamines, aminoacids or dicarboxylic acids and the resulting carboxyterminal or aminoterminal groups are condensed with D-analogs of aminoacids or peptides. The peptide containing D-aminoacids can be also stepwise synthetized on the surface of the carrier. The specific sorbents are further used as insolubilized inhibitors in the affinity chromatography of proteolytic enzymes. They do not undergo an irreversible inactivation during repeated application and are suitable for technological purposes because of their mechanical and hydrolytical stability.

摘要： A polymer aerogel monolith comprising a polymer aerogel having a nitrogen content of greater than seven weight percent impregnated into a mesh. A method of manufacturing an amine-containing polymer aerogel monolith, includes combining a vinyl-containing cross-linking monomer, a vinyl-containing functional monomer, an organic solvent, and a radical initiator into a liquid mixture, applying the liquid mixture to a mesh fabric to produce a monomer-impregnated mesh, heating the monomer-impregnated mesh to produce a polymer aerogel monolith, washing the polymer aerogel monolith with acid to produce an ammonium-containing polymer aerogel monolith, and applying a base to neutralize the ammonium-containing polymer aerogel monolith to produce an amine-containing polymer aerogel monolith. A direct air capture module has one or more amine-containing polymer aerogel monoliths, one or more air flow channels positioned to pass air through the monolith A monolith comprising a poly(alkylamine-co-divinylbenzene) impregnated mesh.

摘要： A composite material of polyurethane foam having a layer of reduced graphene oxide and polystyrene is described. This composite material may be made by contacting a polyurethane foam with a suspension of reduced graphene oxide, drying, and then irradiating in the presence of styrene vapor. The composite material has a hydrophobic surface that may be exploited for separating a nonpolar phase, such as oil, from an aqueous solution.

摘要： 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.
