We are focusing on the development of both low-energy high-performance nanodevices and nanoparticle catalysts for new energy source by controlling the primary (size, shape, composition, etc.) and secondary (regular ordering) structures of various inorganic nanoparticles.
Single Electron Tunneling Devices Using Small Metal Nanoparticles details
[Collaborator] Prof. Yutaka Majima Lab. at Tokyo Institute of Technology
We are aiming at fabrication of single electron tunneling devices, which can trasport the quantized number of electrons between electrodes, by using small metal nanoparticles with large charging energy as coulomb islands.
Application of Plasmonic and Semicondutor Nanoparticles to Optical Materials details
Plasmonic (Au, Ag) nanoparticles (superlattices) are applied to new chemical reactions induced by enhanced electric field and to non-linear optical devices. Also we synthesize high photoluminescent semiconducor nanoparticles.
High-Performance Magnetic Devices using Ferromagnetic Nanoparticles details
[Collaborator] Prof. Hiroshi Kitagawa at Kyushu University, TOYOTA Moor Corporation, Ltd.
We are aiming at fabrication of ultrahigh density magnetic recornding media and exchange-coupled nanocomposite mangets using ferromagnetic (FePt, CoPt, FePd) nanoparticles.
Phase-Segregation Control and Unique Properties of Inorganic Nanoparticles details
Phase-segregation manner is another parameter for determining the properties of inorganic nanoparticles. Anisotropically phase-segeregated inorganic nanoparticles are synthesized on a basis of seed-mediated growth method.
Nanoparticle Catalysts for Energy Conversion details
[Collaborator] Prof. Kazunari Domen at The University of Tokyo
We are synthesizing novel catalysts for energy conversion, such as water splitting by visible light and methanol steam reforming.
