Jun-ichi MATSUSHITA
[Chairman & Professor, Ph.D.] Graduated from Department of Materials Science &
Engineering, Graduate School of Engineering, Toyota Technological Institute, Japan

仭Specialty: Ceramics processing, materials reaction engineering
仭Research subjects: 1. Prototype manufacturing of ceramics, 2. Materials reaction 
engineering based on reaction mechanism, 3. Characterization of ceramic properties

仭Important scientific memberships: Ceramic Society of Japan, Japan Powder and Powder 
Metallurgy, Materials Research Society

仭Research Content: Various ceramic materials exist, each with excellent properties, such 
as high hardness, heat-resistance, high dielectric constant, electric conductivity, 
piezoelectricity, or safe bio-compatibility, respectively. New ceramics with new properties 
are subject of research and development. For the research of ultra-high temperature 
environment ceramics a research grant application was successfully accepted by the 
ministry of science and education. Also, prototype production of the next generation of 
ceramics for space applications and renewable energy sources, namely novel non-oxidic 
ceramic prototypes based on Boride, a high temperature oxidation process using the 
reaction mechanism and high temperature characterization are research themes. At a 
research project on bioceramics based on a sabbatical in University of Cambridge 
University, UK, excellent conformity with the living body and high mechanical properties 
were achieved. Furthermore, research on functional ceramics and their applications with the 
feasibility check for possible industrialization, for example in fluorescence, non-electrostatic 
charging, absorption and so on, is also one of studied themes.

Yutaka YAMADA
[Professor, Ph.D.] Graduated from from Department of Metallurgical Engineering, Graduate
School of Engineering, Tohoku University, Japan

Specialty: Research on superconducting materials and their applications
Research Subjects: 1) High-Temperature superconducting (HTSC) materials for use as current leads or electric power cables.2) Improvement of the critical current of MgB2 materials for use in liquid hydrogen technology.
Important Publications: 1. Y. Yamada, M. Nakatsuka, A. Nitta, K. Tachikawa and H. Kumakura, Superconducting Properties and Structure of In-situ MgB2 Tapes with SiC and TiC Addition Prepared by Hot Pressing, IEEE Transactions on Applied Superconductivity, 17 (2007) 2911-2914.

Important Scientific Memberships: Japanese Institute of Metals, Japan Institute of Electric Engineers, Cryogenic Association of Japan, Japan Welding Society
Research content: Transportation with linear motor cars, electric power storage and electricity transmission, magnetic resonance imaging (MRI) in medicine, computer information and communication science are some of the wide fields, in which research of the superconductors is being expected to play an important role as future key technology, especially after the recent discovery of ceramics with high critical field and high critical temperature (Tc). Research activities focused on the relations between processing and fundamental properties of the high-Tc superconducting ceramics have greatly increased, compared to the conventional metallic superconductors. In other words, the difficult; processing for ceramics for bulk, as well as for wires, has been performed and the relationship between micro-structure, composition and superconducting properties and their influence are evaluated aiming for possible applications. Especially the critical electric current density, that is the value of maximum electric current, which can flow through the unit area of the superconductor at zero electric resistance, is considered as the key factor for realization devices. Recently JR Central announced that the linear motor car connection in about 40 min between Tokyo and Nagoya will be realized in 2025. This will be worldwide the first large-scale application of zero-resistance electric wires and will be a considerable contribution to save the environment.

Stuttgart, Germany

仭Specialty: Materials development, Materials physics

characterization of diffusion bonded metal compounds, 3. Development of perovskite based 
functional ceramics
仭Important Publications: 乽Increase of effective mass of Nb-doped SrTiO3 for 
thermoelectric applications乿乮arxiv/condmat-0510013乯, 乽Improvement of interfaces at nano
-ceramics乿乮J. Cer. Proc. Res., 4 (2003) 10, 5(2004) 30乯丄乽Mobile misfit dislocations at TiAl/

仭Important Scientific memberships: Japanese Institute of Metals (JIM), Japan Physical 
society (JPS), German Physical Society (DPG), German Material Society (DGM)

仭Research Content: 1. For future energy support, thermoelectric materials, which convert 
waste heat into useful electric energy will play an important role. The most important 
factors for high efficiency of semiconductors or semi-metal alloys are carrier concentration 
and the effective mass. According to calculations based on this principle, the promising 
intermetallic phases with Half-Heusler crystal structure are manufactured and 
characterized. 2. For application as in robots, strength and light-weight materials are 
important. The composition, microstructure, dislocation, and other defects on atomic level 
have a large influence on the interface strength. The interface structure is characterized by 
transmission electron microscopy (TEM).3. Superlattices based on the perovskite crystal 
structure show extraordinary functional properties due to their interface structure, such as 
piezoelectric, dielectric, semiconducting and superconduting properties and, when 
understanding the underlying principle, even better materials can be manufactures.
