摘要:
The present invention concerns a method of preparation of nanoparticular metal oxide catalysts having a narrow particle size distribution. In particular, the invention concerns preparation of nanoparticular metal oxide catalyst precursors comprising combustible crystallization seeds upon which the catalyst metal oxide is co-precipitated with the carrier metal oxide, which crystallization seeds are removed by combustion in a final calcining step. The present invention also concerns processes wherein the nanoparticular metal oxide catalysts of the invention are used, such as SCR (deNOx) reactions of nitrogen oxides with ammonia or urea as reductant, oxidations of alcohols or aldehydes with dioxygen or air to provide aldehydes, ketones or carboxylic acids, and photocatalytic oxidation of volatile organic compounds (VOCs).

A cannula device suitable as a component in a base part of an infusion set. The cannula device comprises a housing and at least one membrane together defining at least one cavity adapted to receive a piercing member of a connector, the cannula device further comprising a cannula mounted in said housing and being in fluid communication with said at least one cavity, wherein the device can receive the piercing member of a connector from more than one direction, and the housing has such a geometry that the cannula can extend from the base part in more than one direction.
摘要:
The present invention relates to a method for sterilization or disinfection of an object or a composition using a water soluble precursor for a highly reactive species and UV radiation. The method comprising contacting of said object or composition with a water soluble precursor for a highly reactive species in the presence of water, and irradiating said object or composition with UV radiation having a peak wave length and intensity allowing the in-situ conversion of said at least one precursor into a highly reactive species. The method generates in-situ the highly reactive species from a combination of one or more precursors under the influence of electromagnetic radiation. The radiation is focused on the region to be disinfected or sterilized and generates from the precursors the highly reactive species. The precursors are preferably selected from non-toxic environmental benign compounds. Only under irradiation the one or more precursors give rise to the creation of the highly reactive species. The reactive species have a short lifetime reverting to stable benign compound. Examples of highly reactive species are hydroxyl radical, NO radical, ozonide and CIO.

The invention relates to microcapsules comprising one or more active substances embedded in a matrix material and comprising a powdering agent, said microcapsule further comprising a component which is the product of the reaction between at least one component in said matrix material and at least one component in said powdering agent, and which microcapsule is obtainable by a process which comprises the steps of - providing a solution or dispersion of said matrix material, - adding to said solution or dispersion said at least one active substance, - treating the mixture thus obtained to prepare a solution or dispersion of said at least one active substance and said matrix material, - finely dividing and drying the solution or dispersion thus obtained to prepare a mass of particles each containing the active substance embedded in the matrix material, - adding simultaneously with said finely dividing and drying step said powdering agent, whereby said powdering agent comprises said at least one component, which is able to react with said at least one component in said matrix component, as well as the method itself. The microcapsules of the invention may be used in products, such as foods, food supplements, beverages, pharmaceutical or veterinary products, feeds or feed supplements, personal care products or household products.
摘要:
Formation of nitrogen fixing root nodules in legumes is induced by perception of lipochitin-oligosaccharide signal molecules secreted by compatible Rhizobium bacteria, which triggers a common symbiotic pathway. The present invention provides a spontaneous nodule formation (snf1-5g) mutant, in which the formation of symbiotic nodules is deregulated, leading to nodule development in the absence as well as in the presence of Rhizobium bacteria and/or exogenous rhizobial signals. The invention further provides an isolated DNA sequence encoding a mutant chimeric Ca2+/calmodulin dependent protein kinase whose activity results in this `gain of function′ phenotype of spontaneous nodule formation. Furthermore the snf1-5g gene is shown to confer a spontaneous nodule formation phenotype to plants having a nodulation deficient genetic background. A gene of the invention, that confers a spontaneous nodulation phenotype, has utility for the transfer and establishment of nitrogen fixing capability in non-nodulating plants, and thereby reducing the nitrogen fertilizer dependence of non-nodulating crop plants.
