摘要:
The present invention is a method for producing a laminated body, comprising the steps of: (1) preparing a base substrate having a surface formed of a single crystal which is different from the material constituting the Al-based group-III nitride single crystal layer to be formed; (2) forming an Al-based group-III nitride single crystal layer having a thickness of 10 nm to 1.5 µm on the single crystal surface of the prepared base substrate; (3) forming on the Al-based group-III nitride single crystal layer a non-single crystal layer being 100 times or more thicker than the Al-based group-III nitride single crystal layer without breaking the previously-obtained Al-based group-III nitride single crystal layer; and (4) removing the base substrate. The method provides a substrate which can be suitably used as a base substrate for producing an Al-based group-III nitride single crystal self-supporting substrate, of which surface is formed of a single crystal of an Al-based group-III nitride, and which is free from cracking and warpage.

The present invention provides an organic material that is characterized by including a rigid matrix and a dye having a phosphorescence lifetime of 0.1 seconds or more in a rigid medium at 77 K and that exhibits such a strong and long-lived phosphorescence as to be recognizable with the naked eyes even at ordinary temperature: namely, an ordinary-temperature-phosphorescent organic material.

A method for measuring a test substance whereby the test substance in a sample can be specifically measured without using an antibody against the test substance; an aptamer molecule used therefor; and a method for creating the aptamer are disclosed. An aptamer capable of hybridizing with an oligonucleotide when it is bound to a test substance, but is incapable of hybridizing with the oligonucleotide when it is not bound to the test substance, is utilized. The aptamer is brought into contact with a sample, and the aptamer bound to the test substance is brought into contact with an immobilized oligonucleotide which hybridizes with the aptamer, to bind the aptamer to a solid phase, followed by measurement of the aptamer immobilized on the solid phase.

摘要:
Disclosed is a reactive flame retardant which provides a resin with excellent flame retardance even when it is added in a small amount while being prevented from bleedout. Also disclosed is a flame-retardant resin processed article obtained by using such a reactive flame retardant. An organophosphorus compound represented by the general formula (I) below, wherein at least one or more of X 1 -X 3 represent a group containing phosphorus and having a terminal unsaturated group, is used as a reactive flame retardant which is reactive with resins. A flame-retardant resin processed article can be obtained by solidifying the resin composition containing the organophosphorus compound and then reacting it through heating or application of radiation.
摘要:
A rotor for a rotary electric machine includes a rotor core made of magnetic material, and being in the form of a disk, and a plurality of magnet sets each including a pair of permanent magnets whose polarities are identical to each other. The magnet sets are arranged circumferentially in the rotor core so that the polarities of the magnet sets change alternately. The rotor core includes nonmagnetic portions each formed between adjacent two of the magnet sets.
