About Engineering Science and Mechanics

The aim of this course’s curriculum and research activities is the conception and creation of new functions that are in harmony with people and the environment. Research with a basis in mechanical engineering spans five fields—energy and the environment, materials sciences, mechanical controls, manufacturing and processing processes, and applied micro- and nano-technologies— also incorporating various branches of the fields of engineering, science, and medicine.

Research Domain

micro- and nano-technologies, next-generation robots, reusable energy, intelligent machines, function design, space, vibration analysis, controls, natural energy sources, heat pumps, tribology, advanced safety vehicles, human-machine interfaces, functional materials, micromachines, molecular robots

Hydrogen storage for future hydrogen society

Akito Takasaki

Hydrogen is now stored as gas phase in high pressure cylinders, whose volumetric and gravimetric capacities are quite low. Alternative method to store hydrogen is to store it as liquid form, but it requires low temperatures. Recently, hydrogen storage in solid materials has attracted a great attention because of high volumetric capacity and safety. After discovery of an Al-based quasicrystal alloys in 1984, we have been working for hydrogen storage in Ti-based quasicrystals to investigate the total hydrogen performance, because of their unique structures. On the other hand, magnesium hydride (MgH2) is one of the most promising candidates for hydrogen storage materials, due to its high hydrogen storage capacity with a theoretical value of 7.6 wt.%. However, the practical use of MgH2 for hydrogen storage is limited, due to its high thermodynamic stability and slow hydrogen kinetics. In our laboratory, we also work for MgH2 to improve its total hydrogen performance after doping some catalysts. Instead of these hydrogen storage materials, we also work for electrochemical hydrogenation for some alloys, production of shape memory alloys, oxygen storage materials and thin metallic films, and novel industrial application of biomass.

Proposed structural model for Ti-based quasicrystal, belongs to a two-shell Bergman cluster, which is different from normal crystal structures.

Through the research and development of a robot as an intelligent mechanical system, we will create the new concept of the robot and its realization, and we will develop technologies contribute to the society by improving the mechanical system around us more intelligent using robot technologies.
It is very important how to design the concept of the robot system, and we should think the system as a human centric robotics because robots are always support human beings.
Although the market of the robot now is not so big, we expect the robot will be inevitable in the society with decreasing birth rate and increasing elderly. We will research the robot with an objective of the system clearly.

The vision of the Department of Engineering Science and Mechanics is to develop professionals with advanced skills by capitalizing on engineering/technology know-how and academic intellect to realize innovations that serve a noble function. The Department prepares students to be able to comprehend the current state of science and technology from a global perspective, and then to envisage the next generation of technologies to build a harmonious relationship between mechanical engineering and humanity, which encompasses the interpersonal environment and associated emotional influences.

  1. An engineer with ethical responsibilities and concerns, able to constantly evaluate mechanical engineering requirements from a global rather than a human-centered perspective.
  2. A proactive engineer who understands phenomena and events, able to analyze and act appropriately.
  3. An interdisciplinary approach to understand mankind and mechanics incorporating technology and resource/environment/culture/society/economy from an engineering perspective, ultimately transforming those concepts into an innovative design.

The Department of Engineering Science and Mechanics looks for people based on the type sought by the College of Engineering, with the ambition to be the following types of engineers; people who aim to harmonize mechanical engineering and humanism, including the environment and human sensitivities, with a broad-based understanding of the current state of science and technology.

  1. Those who aim to be engineers who have mastered a wide range of basic engineering and technical knowledge.
  2. Those with an interest in the engineering and technology that aims to create new functions through the application of new knowledge, and giving form to the functions that exist within all of mechanical engineering and technology.
  3. Those who are interested in creating designs with an eye to humans and machines, and explaining the physical and chemical phenomena and mechanisms that exist within machines and systems.

Many of our graduates are employed in a diverse range of industries including automobiles, heavy electric, home appliances, railways, and precision equipment. Graduate professionals from the Department of Engineering Science and Mechanics are working at the forefront and are often stated as being both competent and dependable. The reason behind the success is the vision of the department, which is to nurture students with an “Interaction skills with manufacturing products” and the “vitality to take action” in order to become professional engineers and researchers, extensively dedicated towards the realization of a sustainable society.
