摘要:
A method for depositing a magnesium oxide thin film on a substrate by a laser abrasion method using a sintered body or single crystal of magnesium oxide as a target. In this method, a flat processed film made of magnesium oxide having a (111) plane as its front surface is prepared, using a substrate made of strontium titanate having a (111) plane as its principal surface or yttria-stabilized zirconia having a (111) plane as its principal surface, by directly depositing a film on the principal surface of the substrate and epitaxially growing the film.

摘要:
The SrTiO3 buffer layer is formed by lamination of the Sr2+O2− layer and the Ti4+O24− layer. The surface of the buffer layer is terminated with the Ti4+O24− layer. On the buffer layer, a LaAlO3 thin film layer is formed. The thin film layer includes a La3+O2− layer and an Al3+O24− layer alternately laminated in order on the SrTiO3 buffer layer.

The present invention provides a catalyst substance that is stable and performs well in the synthesis of ammonia, one of the most important chemical substances for fertilizer ingredients and the like. The catalyst substance exhibits catalytic activity under mild synthesis conditions not requiring high pressure, and is also advantageous from a resource perspective. Further provided is a method for producing the same. This catalyst comprises a supported metal catalyst that is supported on a mayenite type compound including conduction electrons of 1015 cm−3 or more and serving as a support for the ammonia synthesis catalyst. The mayenite type compound used as the support may take any form, including that of powder, a porous material, a sintered body, a thin-film, or a single crystal. Use of this catalyst makes it possible to increase the electron donating ability toward a transition metal.

The invention is a process of using, as a reducing agent, a 12CaO.7Al2O3 electride containing electrons in a number of 1019 or more and 2.3×1021 cm−3 or less in its cages to subject a carbonyl compound to reductive coupling in a solvent, thereby synthesizing a diol or polydiol. The invention is also a process of reducing a ketone compound in a solvent, thereby synthesizing a secondary alcohol or diketone compound. According to the process of the invention, it is possible to synthesize a diol or polydiol, or a secondary alcohol or diketone compound through simple operations in a short period without using an expensive and harmful metal hydride or metal salt nor limiting the atmosphere for the synthesis to an inert gas atmosphere as in conventional processes.

摘要:
In an electride C12A7 provided by replacing free oxygen in 12CaO.7Al2O3 with electrons, a material having metallic electroconductivity and an electric conductivity of more than 5×102 S/cm at room temperature could not have been produced without difficulties. An electride 12CaO.7Al2O3, which has metallic electroconductivity and has an electric conductivity of more than 5×102 S/cm at room temperature, can be produced by heat-treating titanium metal vapor and 12CaO.7Al2O3 single crystal, sinter, or thin film at a temperature above 600° C. and below 1,450° C. for less than 240 hours. Further, thermoelectric field electron release can also be realized using an electron release chip fabricated from the electride.
