摘要:
A Mg-doped high-temperature superconductor having low superconducting anisotropy includes a two-dimensional layered structure constituted by a charge reservoir layer and a superconducting layer, wherein some or all atoms constituting the charge reservoir layer are Cu and O atoms, metallizing or rendering the charge reservoir layer superconducting, a portion of the Ca of the Cu n Ca n-1 O 2n constituting the superconducting layer is replaced by Mg, increasing superconductive coupling between CuO 2 layers, a thickness of the superconducting layer is increased, and therefore coherence length in a thickness direction is increased based on the uncertainty principle, lowering superconducting anisotropy.
摘要:
A thin-film fabrication method includes a spray step in which at least one thin-film composition material in liquid form is sprayed into a vacuum vessel via a spray nozzle provided for each thin-film composition material and deposited on a substrate, and a heat treatment step in which the material deposited on the substrate is heat treated. The substrate temperature in the spray step and/or the heat treatment step is controlled within a prescribed temperature range.

摘要:
A surface hydrophobic active carbon is disclosed which has undergone a treatment with trimethyl chlorosilane and exhibits a silicon concentration on the surface thereof, Si 2p /C 1s , in the range of 0.005 - 0.03 as determined by X-ray photoelectron spectroscopy and a humidity for starting adsorption of water in the range of 45 - 60% as determined from the equilibrium adsorbed water content curve, and a method for the production of a surface hydrophobic active carbon is disclosed which comprises exposing active carbon to trimethyl chlorosilane, allowing the exposure to continue for a prescribed length of time, evacuating the ambience, thereby removing excess amount of trimethyl chlorosilane, and subsequently heating the active carbon under a vacuum.
摘要:
An agent for increasing the sugar content and/or decreasing the acid content of plant fruits has as a substantial main component thereof a fluorine-containing ,8-indolebutyric acid compound represented by the general formula:
(wherein Y stands for one member selected from the class consisting of hydroxyl group, alkoxy group, amino group, and alkyl amino group and R 1 and R 2 independently stand for one member selected from the class consisting of hydrogen atom, halogen atom, alkyl group, alkoxy group, aryl group, nitro group, amino group, and alkyl amino group). A method for producing ripe fruits having a high sugar content and/or a low acid content by causing the fluorine-containing β-indolebutyric acid compound mentioned above to adhere to unripe fruits on plants and plants bearing fruits and subsequently allowing the fruits to mature.
摘要:
A substituted fluorine-containing β-indolebutyric acid compound represented by the formula:
where in Y stands for one member selected from the group consisting of hydroxyl group, alkoxy group, amino group, and alkylamino group, at least one of R¹ and R² stands for one member selected from the group consisting of halogen atom, alkyl group, alkoxy group, aryl group, nitro group, amino group, and alkylamino group, and the remaining one, if any, for a hydrogen atom, a plant growth regulating agent having as a substantial main component thereof the substituted fluorine-containing β-indolebutyric acid compound, and a method for regulating the length of roots sprouting from plant seeds and the length of hypocotyls by causing adhesion of the substituted fluorine-containing β-indolebutyric acid compound to the plant seeds.
摘要:
The invention provides a method for the separation of nitrogen and carbon dioxide at elevated temperatures by using a ceramic separating material. The ceramic may be selected from sepiolite in the unmodified form, sepiolite which has been heat-treated, and sepiolite which has had part or the whole of the exchangeable cation thereof replaced with zinc ion and which has been subsequently subjected to a heat treatment.
