WPI Advanced Institute for Materials Research (WPI-AIMR), Tohoku University 東北大学材料科学高等研究所 Japan
Established in 2007, the Advanced Institute for Materials Research (AIMR) at Tohoku University in Sendai, Japan, has been conducting cutting-edge research in materials science for over a decade. It was launched as one of the research centres founded under the World Premier International Research Center Initiative (WPI) of the Japanese government, which promotes the establishment of world-class science hubs. In 2017, the AIMR became a member of the WPI Academy, which consists of WPI centres that have achieved world-premier status.
The AIMR has about 100 leading researchers, including 28 internationally renowned principal investigators. About 40% of these researchers are from overseas. The institute has four materials-related groups, which are exploring the physics of materials, non-equilibrium materials, soft materials, and devices and systems. In addition, the AIMR’s Mathematical Science Group is pursuing mathematics−materials science collaboration with these four groups.
The institute has a strong focus on interdisciplinary research and is conducting research in the overlap between fields such as materials science, physics, chemistry, and precision, mechanical, electronics, and information engineering. Furthermore, under the leadership of its director, Motoko Kotani, many of its researchers are exploring the interface between materials science and mathematics — a rich seam of new science. This collaboration between these two fields is unique at an institutional level.
The AIMR is strongly promoting global collaboration. It has established three joint centres with the University of Cambridge in the UK, the University of Chicago in the USA and Tsinghua University in China. It also has nine international partner institutions in Europe, the USA and Asia. Furthermore, the AIMR encourages researcher exchange through its Global Intellectual Incubation and Integration Laboratory (GI3 Lab).
The institute is also actively engaged in developing devices and systems based on its research, contributing to society by addressing global problems.
Following the selection of Tohoku University as a Designated National University by the Japanese government in 2017, the AIMR will play a major role in establishing a new materials research centre at the university.

A low-temperature way to make porous nitrogen-doped graphene, which could have applications from next-generation batteries to carbon-free fuels, has been developed by scientists at the Advanced Institute for Materials Research (AIMR) at Tohoku University.
Many promising renewable-energy applications, including fuel cells and metal–air batteries, rely on splitting molecular oxygen (O2). Hydrogen fuel cells, for example, combine hydrogen and oxygen to release electricity, producing water as the by-product. But until now, highly active oxygen reduction reaction (ORR) catalysts have required platinum, a rare and expensive metal.
AIMR researchers have now produced a high-performance ORR catalyst from inexpensive, earth-abundant elements carbon and nitrogen. They developed a low-temperature, nickel-based method for growing porous, single-atom-thick carbon sheets called graphene. To improve its electrocatalytic ORR performance, the researchers doped the graphene with a high number of nitrogen atoms.
When the team tested their material as an electrode for a zinc–air battery, it showed comparable performance to a platinum-based electrode and a higher durability.
