Division of Applied Chemistry and Biotechnology

Overview

Educational Policy

イメージ

Development of science and technology today is backed by new materials and their use in various fields. The educational program of this division focuses on systematic understanding of the basic principles of materials and chemical processes to produce them. In the Master’s program, the fundamentals of materials and their transformation are taught through lectures and laboratory work. The relationship among the structures, properties, and functions of materials are emphasized. Work ethics and importance of returning the research results to the society are also taught. In the Doctor’s program, students are trained to become independent researchers who can solve difficult problems with flexibility through deep understanding of materials.

Learning applied chemistry to live in harmony with the earth; the key words are 'environment' and 'bio'

The aim of this course is to promote understanding of materials and chemistry behind them and to train students to become experts on development of new materials and processes by fresh concepts and techniques. A sustainable society in the 21st century requires development of environmentally benign materials. Chemical processes to produce them need to be benign to the environment as well. Extraction of the functions that living things have from the chemical standpoint and to develop materials and processes which imitate or utilize them is an important direction to follow in chemistry. Accordingly, the course consists of four areas of education and research, i.e., ‘bio-functional chemistry’, ‘sustainable organic chemistry’, ‘inorganic and analytical chemistry’, and ‘chemistry for efficient conversion of natural resources’. Highly specialized education is given in each area and, with the cooperation of other areas, students are expected to acquire wide viewpoints.

Brief description of each area is as follows.

Bio-functional Chemistry

Biological functions are based on elaborate interactions among biomolecules. We investigate these interactions, from physicochemical and structural viewpoints, to extract the novel design principles for material synthesis and process development. Our research includes DNA- and enzyme-immobilized materials, microreactors and nano/ microparticles for analytical applications, biodegradable polymers, biomimetic conductors, magnetic polymers, and genetic engineering of proteins and biosynthetic pathways.

Sustainable Organic Chemistry

This subdivision covers the development of environmentally benign and efficient organic synthetic methodology and the design and synthesis of novel organic functional materials. The following topics are to be lectured and studied. 1) synthetic methodology of bioactive compounds for pharmaceuticals and agrichemicals, 2) organic synthetic processes utilizing characteristic properties of heteroatoms (nitrogen, sulfur, fluorine, etc.) and transition-metal catalysts for organic synthesis, 3) synthetic and mechanistic organic photochemistry, 4) self-assembling of organic molecules and supramolecular chemistry, 5) advanced organic functional materials such as organic electroluminescent, liquid crystalline, and photochromic materials.

Inorganic and Analytical Chemistry

The prime focus of our research centers around the preparation, processing, and property evaluation of a diverse array of high performance and environmentally friendly inorganic materials. We work on the development of less toxic alternative materials as well as the recycling of resources and energy to minimize pollution. Also, this group develops atomic and/or molecular-leveled chemical analytical techniques to investigate the properties of various novel microstructures and heterogeneous interfaces.

Chemistry for Efficient Conversion of Natural Resources

TOur goal is to develop highly efficient and environmentally benign chemical processes for the effective utilization of biomass, solar energy, and fossil resources by the following methods: the creation of novel reaction sites with structurally controlled hetero-interfaces at a molecular and atomic level, which enables highly effective energy conversion, and the development of highly efficient and selective catalysts controlled at a nano-structural level. In particular, 1) structurally refined synthesis of inorganic/organic hybrid catalysts for molecular recognition reactions, 2) creation of novel nano-surfaces controlled at molecular level and in situ dynamic structural analysis, 3) development of novel catalytic processes for the useful material manufacturing from plant origin resources, 4) determination of the real structures of well-defined surfaces and nano-particles in atomic scale, and development of electrocatalysts with ultra high efficiency for energy conversion.

Students, completing the program, get positions in chemical, energy-related, medical, and food industries as research chemists or engineers. There are also positions in electric, electronic, mechanic, and information industries. Teaching positions are also available.
