摘要:
A thermoelectric conversion material capable of increasing the conductivity, and increasing the Seebeck coefficient is provided. The thermoelectric conversion material according to the present invention contains a carbon nanotube, and has a G/D ratio of 25 or more as determined by Raman spectroscopic measurement, an electrical conductivity of 500 S/cm or more, and a Seebeck coefficient of 50 µV/K or more.
摘要:
A silicon carbide layer is thermally etched by supplying the silicon carbide layer with a process gas that can chemically react with silicon carbide, while heating the silicon carbide layer. With this thermal etching, a carbon film (50) is formed on the silicon carbide layer. Heat treatment is provided to the silicon carbide layer to diffuse carbon from the carbon film (50) into the silicon carbide layer.
摘要:
L-cysteine can be produced inexpensively and efficiently by using a bacterium belonging to the family Enterobacteriaceae modified to reduce activity of O-acetylserine sulfhydrylase B thereof, the bacterium being modified so that the C terminal region of its thiosulfate-binding protein is deleted, and the bacterium having an increased ability to produce L-cysteine in the presence of a sulfate.

摘要:
Objects of the invention are to provide modified carbonyl reductases having improved reactivity in the presence of halogen atoms in comparison with a wild-type enzyme, as well as a method for efficiently manufacturing an optically active alcohol using these enzymes. Modified carbonyl reductases having improved reactivity in the presence of halogen atoms in comparison with the wild type were isolated from a library of modified carbonyl reductases prepared by introducing random mutations into the wild-type enzyme gene. There are also provided enzymes as well as DNA encoding the enzymes, transformants producing the enzymes, and a method of efficiently manufacturing an optically active alcohol using these.
