The compositions contain a wide range of different functional groups such as mercapto, sulfide, thiourea, amines and amides in the same composition and each of these functional groups are present in an array of numerous different oligomers, configurations and stereochemistry. These functional groups have a strong affinity for metals and particular targets. Combining a high number of these functional groups together in the same composition enhances the overall binding affinity of the functionalised material. Combination with different structural configurations further enhances the capacity to bind to diverse structural variations in the targets found in actual process, product and waste streams. This multitude of binding mechanisms enables very high levels of purification and target removal as well as selectivity to be achieved in product, process and waste streams. The compounds are useful for the purification of products and for the removal of unwanted organic and inorganic compounds from product, process and waste streams, as chromatography medium for the purification and separation of metals, metal complexes and organic and biological compounds, for solid phase extraction, for solid phase synthesis, for metal mediated heterogeneous catalysis, for metal ion abstraction and for the immobilisation of bio-molecules. 2.

METHOD FOR CONTINUOUS PRODUCTION OF ALIGNED NANOSTRUCTURES ON A RUNNING SUBSTRATE AND RELATED DEVICE

Номер: US20160289826A1

The invention relates to a method for continuously manufacturing aligned nanostructures on a running support, which comprises conveying the support through a heated space and synthesising, in this space, aligned nanostructures on the support by catalytic chemical vapour deposition. The heated space is divided into n consecutive zones in the conveying direction of the support (n being an integer ≧2), and the synthesis of the nanostructures results from heating and injection operations, in each of these n zones, of a flux of an aerosol containing a catalytic precursor and a source precursor of the material of the nanostructures to be formed, carried by a carrier gas. The injection operations are made by modifying, in at least two of the n zones, at least one parameter chosen among the flow rate of the carrier gas flux, the chemical composition of the carrier gas, the mass concentration of the catalytic precursor in the catalytic precursor and source precursor mixture. The invention also relates to a device for implementing this method. 1: A method for continuously manufacturing aligned nanostructures on a running support , the method comprisingconveying the support through a heated space in a conveying direction, andsynthesising, in this space, the aligned nanostructures on the support by catalytic chemical vapour deposition,whereinthe heated space is divided into n consecutive zones in the conveying direction of the support, n being an integer higher than or equal to 2,the synthesis of the nanostructures results from heating operations and injection operations, in each of the n zones, of a flux of an aerosol containing a mixture of a catalytic precursor and a source precursor of a material of the nanostructures to be formed, conveyed by a carrier gas, andthe injection operations are made by modifying, in at least two of the n zones, at least one parameter selected from the group consisting of a flow rate of the carrier gas flux, a chemical composition of the carrier ...
