The students will obtain the creativity applicable to various stages of development, from invention of new materials by applying chemistry to designing/constructing/operating processes to put the basic ideas/findings into practice.

Program of education

The educational curriculum of the Chemistry and Chemical Engineering Program consists of KIJ Phase 1 (Knowing Is Joy) and KIJ Phase 2 (Knowledge Integration for professional Job), which aim to help students become talented people with a combination of the broad foundations and the high levels of specialist knowledge required to contribute to society in fields related to chemistry.

KIJ Phase 1 (Knowing Is Joy):

From the enrollment to the first semester of sophomore year, students learn the fundamentals of chemistry and engineering. This fundamentals includes not only natural science and basics of engineering, but also social science, communication skills, and engineering ethics, all of which are required for researchers/engineers when they solve the problems with the concern for their roles and responsibilities. For this purpose, subjects are provided for liberal arts , common basics of engineering, chemistry, and basics of applied chemistry and chemical engineering.

KIJ Phase 2 (Knowledge Integration for professional Job):

From the second semester of the second year, students select either the Applied Chemistry Course or the Chemical Engineering Course, advanced specialist courses which allow them to develop their knowledge and techniques and cultivate the ability to solve specialist issues. At the end of the first semester of the sophomore year, students select either the Applied Chemistry Course or the Chemical Engineering Course. From the second semester of the sophomore year, more specialized subjects are provided for each course. Students in the Applied Chemistry Course obtain the ability to design, synthesize, and analyze new materials. In the Chemical Engineering Course, students obtain the ability to design and develop processes/systems for industrial production. Both courses provide laboratory courses and exercise courses in accordance to the lectures of specialized subjects to improve the students’ skills and to strengthen their understanding of knowledge. Finally, in the senior year, the students conduct research works of their own research topics for their bachelor theses. In the research work, the students integrates their specialized knowledge with the professional skills to solve the problems required by the modern society.

In the Chemistry and Chemical Engineering Program, the program of education is accredited by the Japan Accreditation Board for Engineering Education (JABEE), and students are awarded with a certificate marking their completion of a JABEE-accredited program when they graduate. Students who complete the program are qualified to register as associate professional engineers without needing to take the first stage examination for professional engineers.

Curriculum

  • First year
  • After the enrollment, all the students learn common background of engineering, including various fields of engineering, ethics, information security, intellectual property (such as patent). Also students learn liberal arts. In the 3rd and 4th terms, students learn basic organic chemistry, basics of chemical engineering, and basic inorganic chemistry, as the common basics for Chemistry and Materials field. At the end of the first year, the students select specialized education program.

  • Both courses provides specialized subjects for lectures, laboratory courses and exercise courses as well as lectures in common. By integrating knowledge the students learn in lectures and skills they obtained in laboratory/exercise courses, the students acquire the ability to comprehensively apply their knowledge to solve problems.

  • Fourth year
  • Each students is assigned to a laboratory, where they conduct research works of their own research topics for their bachelor theses. In the research work, the students integrates their specialized knowledge with the professional skills to solve the problems required by the modern society.

Introduction to classes

  • Basic Physical Chemistry
  • Physical chemistry is the study of the constitution and properties of, and changes in substances. Chemical phenomena are interpreted in terms of physics using equations from the perspective of the energy transfer and the motion of molecules. In Basic Physical Chemistry, students study the basics of thermodynamics, which covers the energy transfer, changes in the states of substances, and chemical equilibrium. This subject forms the basis of fields such as organic chemistry, inorganic chemistry, and analytical chemistry.

  • Inorganic Synthetic Chemistry
  • Students develop an understanding of chemical states, compositions, and reactions, etc. of substances, and learn about the investigation and molecular design of the diverse properties of materials using advanced analytical methods. They acquire specialist knowledge regarding the synthesis of inorganic substances with new functions that can also be applied to fields such as energy and electronics and skills that can be applied to the synthesis of inorganic materials.

  • Diffusional Operations I
  • Diffusion refers to the movement of certain components and heat between different substances. Operations using diffusion occupy an important role in chemical industry. In Diffusional Operations I, we seek to grasp the principles of separation and concentration, with a particular focus on areas such as the elimination of impurities from raw materials, and the concentration of the specified substance. We then study the method of utilizing the relational expression that is acquired by applying those principles to each of the operations to determine the form, size, and operation conditions of the equipment.

Advanced research pursued by the program

Striving to preserve the aquatic environment

Chemical technology is essential for producing a number of different materials and products that help to ensure the happiness of mankind while at the same time taking into consideration the environment and resources. It is used in a wide range of areas, such as utilizing resources and energy effectively, developing materials with advanced functions, and preventing environmental pollution.
At my laboratory, we research techniques for treating waste water. Waste water contains dye and other such substances that are difficult to process. We are developing microreactors that use ozone to ensure effective oxidative degradation of pollutants that are difficult to process. By making the height of the passage for draining ozone gas and waste water several hundred micrometers it is possible to decolorize and degrade the dye in several minutes. We are also researching methods of processing waste water using plants and microorganisms. Artificial wetland is—as the term suggests—artificially constructed wetland that is used for the processing of waste water. Artificial wetland is utilized across large areas in regions such as the United States and Europe and Asia for processing not only household drainage water but also livestock waste water and rainwater that has fallen on parking lots. Artificial wetlands take up larger areas in comparison with sewage treatment plants or septic tanks, but require hardly any energy for operating equipment. If processing conditions are set correctly, artificial wetlands can even be used to sufficiently process waste water containing dye. Recently we have been investigating a method to increase the waste water processing functions by supplying oxygen to microorganisms within the wetlands using silicone tubing. As public sewerage systems and factory waste water treatment plants also create large amounts of polluted sludge when processing waste water, we are also researching methods of processing such substances.
Students are also fellow researchers, and we include them when publishing our research findings to a wide international audience. Some of our students have also given presentations at international conferences outside of Japan.
