In Tuesday classes, Prof. Yashima reviews the fluorite-type and perovskite-type structures at an atomic scale, phase diagrams and thermodynamics of inorganic materials. You can learn the electrical conductivity and ionic conductivity of ceramic materials, which are important for clean energy and environments. Through the lecture of Prof. Yashima, the students are able to understand the crystal structure, thermodynamics and properties of ceramic materials and to design the ceramic materials.
In Friday classes, Prof. Komatsu reviews the nature of solid surface. Topics include the preparation, characterization and catalytic properties of nano-particles of pure metals and intermetallic compounds.
Emphasis is placed on quantitative description of catalysis.
At the end of this course, students will be able to:
1) Explain the definition, crystal structure, chemical bonding, phase diagram and thermodynamics of ceramic materials.
2) Explain the properties of ceramic materials and discuss the structure-property correlation.
3) Design the ceramic materials.
4) Obtain the number of surface atoms and catalytically active sites of a metal nano-particle.
5) Explain quantitatively adsorption and reaction on the solid surface.
6) Understand the preparation and characterization of metal and intermetallic nano-particles.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Students are assessed on their understanding of the definition, crystal structure, ionic radius, chemical bonding, phase diagram, thermodynamics and properties of ceramic materials, and quantitative description of adsorption and catalytic reaction on solid surface, preparation and characterization of metal and intermetallic nano-particles. Course scores are mainly based on the reports. Additionally the exercise and quiz in the lectures will be considered in the course scores. Depending on the Corona virus, we might change how to determine the course scores .
It is preferable to study "Inorganic Chemistry I" before this class.
