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 27 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.

Glass-like nanoparticles merge faster than conventional ones

Metallic glass nanoparticles— nanoparticles consisting of metal atoms with in a disordered, glass-like arrangement — coalesce more rapidly than conventional metal nanoparticles, which have regular, crystalline structures.

Metallic glass nanoparticles are potentially useful for many applications, including catalysis and biomedical materials. Like all nanoparticles, metallic glass nanoparticles coalesce with each other over time, which considerably alters their properties. But not much is known about their coalescence behaviour.

Now, researchers from the Advanced Institute for Materials Research at Tohoku University have used transmission electron microscopy to examine the coalescence of metallic glass nanoparticles. This analysis revealed that metallic glass nanoparticles coalesce faster than their conventional counterparts.

Computer simulations revealed that these different coalescence behaviours spring from the different mobilities of atoms on the nanoparticles’ surfaces, which in turn arises from the different nanoparticle morphologies.
