Tokyo University of Agriculture and Technology (TUAT)


Tokyo University of Agriculture and Technology (TUAT) has a long history of improving society through advances in agricultural science and engineering. Ever since its beginnings in the 1870s as two government departments that merged in 1949 to form a university, TUAT has placed a strong emphasis on improving the lives of people in Japan and beyond. Input from a broad range of perspectives is required to address major global challenges such as environmental degradation, energy and food supply issues, and obstacles to realizing a sustainable society. The university’s vision is to realize globally competitive research capabilities and to become a science and technology hub for developing a sustainable society. TUAT is well known for its strong research collaboration with industry and for striving to create new technology.

Institute of Global Innovation Research

In 2014, TUAT was selected by the Japanese government as one of 12 national universities rapidly promoting global research. To enhance the university’s research capabilities in agriculture and engineering, the university established the Institute of Global Innovation Research (GIR). This institute prioritizes research in three key areas: food, energy and life sciences. It is developing strategic research teams with the aim of promoting international collaborations.

Wide range of choices in agriculture and engineering

The university offers a very broad range of courses. Its Faculty of Agriculture has courses in biological production, applied biological science, environmental and natural resource science, eco-regional science, and veterinary medicine. And its Faculty of Engineering offers courses in biotechnology and life sciences, applied chemistry, organic and polymer materials chemistry, chemical engineering, mechanical systems engineering, applied physics, electrical and electronic engineering, and computer and information sciences. The university aims to nurture leadership ability in students and to equip them to solve global issues through the fields of agriculture and engineering.

Well-known alumni

Notable TUAT alumni include Professor Akira Endo, Japan Prize laureate; Lasker-Debakey, Clinical Medical Research Award winner; Morshed Khan, former foreign minister of Bangladesh; Ginandjar Kartasasmita, former minister for mining and energy in Indonesia; Hirohide Hamashima, engineer at Bridgestone F1 Tire; and Susumu Ohno, author of the book Evolution by Gene Duplication.

No going back for more efficient diodes

Electronic devices could use power more efficiently through a new gallium oxide diode with an extremely high reverse voltage resistance.

Future electronics will demand faster and more efficient power supplies, but silicon-based electrical components are reaching their performance limits. A Japanese team including researchers from Tokyo University of Agriculture and Technology built a diode — a component that allows current to flow in one direction and blocks it in the other — by depositing grains of silicon-infused gallium oxide onto a layer of gallium oxide and tin. They used a small silica plate to block the reverse current after it leaves the diode. The diode displayed very low resistance for the forward current, enabling rapid switching, and the silica plate blocked reverse current up to a record 1,076 volts. It also showed excellent thermal stability, performing as well at 200 degrees Celsius as it did at room temperature.

This diode could be mass-produced as high-quality individual gallium oxide crystals can be made cheaply from bulk crystals.
