Abstract: Upon producing a transparent polycrystalline material, a suspension liquid (or slurry 1) is prepared, the suspension liquid being made by dispersing a raw-material powder in a solution, the raw-material powder including optically anisotropic single-crystalline particles to which a rare-earth element is added. A formed body is obtained from the suspension liquid by means of carrying out slip casting in a space with a magnetic field applied. On this occasion, while doing a temperature control so that the single-crystalline particles demonstrate predetermined magnetic anisotropy, one of static magnetic fields and rotary magnetic fields is selected in compliance with a direction of an axis of easy magnetization in the single-crystalline particles, and is then applied to them. A transparent polycrystalline material is obtained by sintering the formed body, the transparent polycrystalline material having a polycrystalline structure whose crystal orientation is controlled.

Abstract: Provided is a method for manufacturing a translucent polycrystalline material with optical properties continuously varying in the material. A slurry including single crystal grains that are acted upon by a force when placed in a magnetic field is immobilized in a gradient magnetic field with a spatially varying magnetic flux density and then sintered. For example, where a slurry including single crystal grains of YAG doped with Er and single crystal grains of YAG undoped with a rare earth material is immobilized in the gradient magnetic field, the region with a strong magnetic field becomes a laser oscillation region that is rich in Er-doped YAG, whereas the region with a weak magnetic field becomes a translucent region rich in YAG undoped with a rare earth material. A polycrystalline material having a core with laser oscillations and a guide surrounding the core are obtained at once.

Abstract: A method for producing an accumulated product of a nano-substance that enables the accumulated product of the nano-substance to be produced at low cost, by a simple process that requires few conditions to be controlled and requires minimal energy, and with good reproducibility. Specifically, a method for producing an accumulated product of a nano-substance, the method including crystallizing a protein in a state where the protein and the nano-substance co-exist within a solvent, thereby accumulating the nano-substance within pores of the protein crystals to obtain the accumulated product of the nano-substance.

Abstract: The present invention relates to a method of screening a potential translational regulatory element of mRNA, which promotes or suppresses the translation efficiency of mRNA in a given translation system, by applying the in vitro evolution principles. Specifically, the present invention relates to a method of screening a potential translational regulatory element of mRNA, comprising the steps of synthesizing mRNAs with random oligonucleotide sequences, which are candidates of translational regulatory elements, introduced into the untranslated regions (UTRs), and selecting mRNAs with altered translation efficiency by virtue of the inserted motifs; to translational regulatory elements screened by this method; and to a method of isolating mRNA with altered translation efficiency in comparison with the native mRNA by using such a screening method.
