摘要:
A method for the production of particles by reacting functional groups on the surface of non-magnetic porous particles with functional groups on the surface of magnetic particles to form a covalent bond, to obtain particles supplemented with magnetic particles covalently bound to the outer part of said particles. Advantages include an increased binding capacity facilitating the use to separate biomolecules such as IgG.
摘要:
A filtration device including a fluid-impermeable housing having a gas inlet and outlet, and containing within the housing first filter media particles of an extended surface area substrate and containing at least one metal impregnant, and second filter media particles of an extended surface area zirconium hydroxide substrate and containing zinc (hydr)oxide. The first or second filter media particles also contain an amine-functional material. The device may be used in atmospheres containing various harmful gases, and may provide particularly useful improvements in breakthrough times for nitrogen dioxide, hydrogen sulfide, ammonia and formaldehyde compared to a device containing only the first filter media particles or only the second filter media particles.

摘要:
The invention relates to an activated carbon, in particular an activated carbon with reactive and/or catalytic activity, said activated carbon being in the form of discrete activated carbon particles, preferably in a spherical and/or grain form. The activated carbon is provided with and/or comprises at least one metal component which has at least one metal-containing ionic liquid (IL) containing, in particular metal ions, preferably based on a metal compound. The invention also relates to methods for producing said activated carbon, to the uses thereof and to materials provided therewith.
摘要:
According to the invention, a method is provided for coating at least in areas a component with a layer of a metal-organic framework (MOF), in which the body is contacted with a solution containing at least one metal salt (MOF precursor), at least one linker, and at least one solvent. The linker in this case can effect the bonding of the MOF layer to the surface of the component and/or the structure of the MOF layer. The method is characterized in that the solution has a temperature gradient, wherein the temperature of the solution immediately at the surface of the component permits the crystallization of an MOF layer on the surface, whereas the temperature of the remaining solution prevents the formation of MOF crystals in the remaining solution. The method can be used for producing components having layers of defined chemical and/or physical properties. Furthermore, the invention comprises components which have at least in areas an MOF layer. A possible use of said components is in sorption refrigeration machines.
