    摘要: The invention discloses a novel method for the preparation of a 2-keto carboxylic acid from carbon dioxide by an enzymatic addition reaction with an aldehyde compound. Carbon dioxide, which can be in the form of carbonate ions, is reacted with an aldehyde compound such as acetaldehyde and propionaldehyde under mild reaction conditions in the presence of a decarboxylase to give a 2-keto carboxylic acid such as pyruvic and a 2-ketobutyric acid by a reverse reaction to the enzymatic decarboxylation reaction. The scope of the invention involves contribution to a solution of the environmental problem of global warming due to carbon dioxide as a greenhouse effect gas in the aerospace.

    摘要: A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

    摘要: To provide a fluorescent having low toxicity and high quantum yield, and a method for producing the same. The fluorescent is a compound comprising each one of I, III and VI group elements having a chalcopyrite structure, has a particle diameter of 0.5 to 20.0 nm and a quantum yield of at least 3% but not more than 30% at room temperature. The fluorescent is produced by: mixing a first solution (solution A), which is prepared by dissolving and mixing copper (I) salt and indium (III) salt in a solution added with a complexing agent coordinating copper (I) and indium (III), with a second solution (solution C) in which a sulfur compound is dissolved; ripening the mixed solution for a predetermined amount of time as a pretreatment; heat-treating the ripened solution under predetermined heat conditions; mixing the ripened solution with the second solution (solution C); and heating thus obtained mixed solution under predetermined synthesis conditions. In addition, a product produced by this production method is subjected to compositing treatment with ZnSe, ZnS or the like to improve the quantum yield.
