Ecological Materials

TANABE Tadao
Course description
The development of industry is supported by materials, which are involved in all fields of engineering. In a recycling-oriented ecological society, it is important to learn the fundamentals for more effective selection and processing of materials and rational design of materials. The class cover a wide range of topics from basic materials to advanced materials, with explanations in English as necessary. The lecture also explain the relationship between humans, society, and nature from global and historical viewpoints. This class begins with a quiz on materials in our daily lives, followed by explanations of the basic knowledge, and a mini-test to check the level of understanding of the lecture content.
Purpose of class
As a foundation of materials in a recycling-oriented ecological society, the first half of the class focuses on understanding the states of solid, liquid, and gas, plasma, and the relationships of these phases as phase diagrams. In particular, regarding materials in the solid state, the nanoscopic level based on atomic and molecular models, the macroscopic level to discuss the properties of objects such as structures and products, and the mesoscopic level to control the structure and structure of solid materials are studied. Several examples are given to help understanding of the framework of materials science. The second half of the course focuses on applied materials, including 1) mechanical properties of structural materials and their applications, 2) electrical and optical properties of materials, 3) properties and control of tool and mold materials in manufacturing, 4) thermoelectric properties and hydrogen technology, and 5) safety and security materials, discussing principles, properties, and application development of materials in relation to the environment.
Goals and objectives
  1. To understand the structure of materials and explain how their physical properties relate to materials and the environment in Japanese and English.
  2. To understand the basics of thermodynamics, and to explain the relationship between heat and changes in various phenomena in materials, including from the viewpoints of materials and the environment, in both Japanese and English.
  3. To understand the fundamentals of mechanical properties of materials, and to explain the advantages and disadvantages of various materials in Japanese and English, including from the viewpoint of sustainability.
  4. To understand the functions of materials (electrical and optical properties, etc.) and to explain the operating principles of various devices in Japanese and English, including from the viewpoint of sustainability.
