Abstract: A sintered magnet contains Sm—Fe—N-based crystal grains and has high coercivity; and a magnetic powder is capable of forming a sintered magnet without lowering the coercivity even if heat is generated in association with the sintering. A sintered magnet comprises a crystal phase composed of a plurality of Sm—Fe—N-based crystal grains and a nonmagnetic metal phase present between the Sm—Fe—N crystal grains adjacent to each other, wherein a ratio of Fe peak intensity IFe to SmFeN peak intensity ISmFeN measured by an X-ray diffraction method is 0.2 or less. A magnetic powder comprises Sm—Fe—N-based crystal particles and a nonmagnetic metal layer covering surfaces of the Sm—Fe—N crystal particles.

Abstract: According to the present invention, methylation of a target DNA in a plant is suppressed quickly and easily without using recombinant technology, and a plant having desired traits is thereby created. In an RNA-directed DNA methylation mechanism, binding between scaffold RNA produced by transcription of the target DNA and an siRNA-AGO4 complex is inhibited.

Abstract: Proposed is a phase shift introduction method, a structure, and a circuit device for eliminating or minimizing a risk associated with dissimilar materials, solving in principle a problem of mixing of a signal current and a control current that occurs due to DC connection of a phase shifter to a signal line, and stably and reliably providing a phase shift that is desired to be introduced without being adversely effected by noise generated by an ambient magnetic field, which is generated due to use of an external power supply. A structure according to the present invention includes a phase shifter 101 and a closed-loop circuit 103 that is directly used for computation or storage, and a quantum phase shift is generated in the closed-loop circuit 103 by using a fractional flux quantum captured by the phase shifter 101 that is DC-separated from the closed-loop circuit 103.

Abstract: A problem to be solved by the present invention is that there is no method for forming a dense structure on a porous structure at low cost. In addition, another object is to provide a high quality and inexpensive structure of a brittle material and a laminate thereof as an intermediate layer for facilitating formation of a dense structure on a porous structure. A structure is provided having a brittle particle assembly having a plurality of brittle particles, wherein the brittle particle assemblies are arranged adjacently to each other, and the brittle particles having a brittle material region in the periphery are crosslinked (connected) by the brittle material region to bond the brittle particles to each other, and thereby form a brittle material crosslinked structure region preventing the mobility of the brittle particles.

Abstract: There is provided a novel ionic composite material that can be molded into various shapes using lignin sulfonic acid as one of raw materials thereof, and having flexibility and elasticity, to significantly improve the strength and toughness and impart complete biodegradability thereto. It was found that a combination of ε-polylysine (ε-PL) which is a cationic polymer that is produced by microorganisms and lignin sulfonic acid exhibits excellent strength and toughness. In addition, ε-PL used in this technology is a biodegradable polymer that is completely degraded by microorganisms and the like in the environment. Since lignin sulfonic acid is also a biodegradable polymer, it is thought that a complex in which ε-PL and lignin sulfonic acid are mixed in this technology will exhibit complete biodegradability, and more applications thereof can be expected when utilizing the strength, durability, and biodegradability thereof in addition to the improved strength and toughness.

Abstract: An organically modified metal oxide nanoparticle includes a core, a first modification group, and a second modification group. The core includes a plurality of metal atoms and a plurality of oxygen atoms bonded to the plurality of metal atoms. The first modification group is a saturated carboxylic acid/carboxylate ligand coordinated to the core. The second modification group is coordinated to the core, and is an inorganic anion having a smaller size than the first modification group and/or a saturated carboxylic acid/carboxylate ligand having a smaller molecular weight than the first modification group.
