摘要： A material system and method for bonding refractory powders in a three dimensional printer. A first particulate component including a refractory material is mixed with a first reactive component to form a particulate mixture. A flat layer of the particulate mixture is dispensed onto a build surface. A liquid binder, which may include a furan monomer and a surfactant, is dispensed by an ink-jet printhead onto the particulate mixture. The particulate mixture may contain a furan-soluble polymer that imposes a capillary attraction for the liquid binder, keeping it situated in the immediate vicinity of where the binder is dispensed. Additionally it provides a sufficient catalytic power to co-polymerize with the furan monomer and form a solid structure. This enables a 3D printer to build strong, accurate parts with high packing density, and to reuse the feed material many times in the printer.

摘要： The present invention relates to a novel process for manufacturing a sugar acid for the use in the agricultural market as an adjuvant wherein the process includes the following steps of providing a reactor and introducing a source of nitric acid, water and a source of starch into the reactor to form a mixture and further includes introducing an external heat source to the mixture to ascertain a mixture temperature of at least 70° C. and discontinuing the external heat source once the mixture reaches about 70° C.; and further enabling an internal heat source in the form of an exothermic reaction to occur between the reagents for at least two (2) hours. The invention also relates to the use of the product as obtained from the process.

摘要： The present invention relates to plant cells and plants that are genetically modified, whereby the genetic modification leads to a decrease in the activity of a starch dephosphorylating LSF-2 protein in comparison to corresponding wild type plant cells or wild type plants that have not been genetically modified. The present invention also relates to means and methods for the manufacture of such plant cells and plants. These types of plant cells and plants synthesise a modified starch. Therefore, the present invention also concerns the starch synthesised from the plant cells and plants according to the invention, methods for the manufacture of this starch, and the manufacture of starch derivatives of this modified starch, as well as flours containing starches according to the invention.In addition, the present invention relates to chimeric genes comprising nucleic acids encoding a starch dephosphorylating LSF-2 protein, vectors, host cells such as plant cells, and plants containing such chimeric genes.

摘要： A process for preparing a cellulose sulfate ester by reacting a hydrated cellulose containing about 4 to about 12 percent by weight of water with dinitrogen tetroxide or nitrosyl chloride in the presence of a proton acceptor and a reaction solvent which is a swelling or solubilizing agent for a reaction product. Alternatively, the cellulose reactant may contain less than about 4 percent by weight of water by washing hydrated cellulose containing in excess of 4 percent of water with a highly polar aprotic solvent to reduce the water content.A process for simultaneously preparing a sulfate ester of cellulose and an alkyl nitrite by reacting a nitrite ester of cellulose with sulfur trioxide or a complex thereof to obtain a mixed nitrite:sulfate ester which is reacted with an organic alcohol containing up to about 10 carbon atoms.A process for simultaneously preparing a sulfate ester of cellulose and a mixture of an organic nitrite and an inorganic nitrate by reacting a cellulose nitrite ester with sulfur trioxide or a complex thereof to obtain a mixed nitrite:sulfate ester in the presence of dinitrogen tetroxide with water then being added and neutralizing by addition of a base.
