| Summary |
In recent years, significant progress has been made in the precise synthesis of “superatoms”—clusters composed of well-defined numbers and types of atoms that possess discrete, atom-like electronic states. The creation of “superatomic materials” by linking and assembling these superatoms has attracted considerable attention as an emerging frontier in materials chemistry. However, the rational design of their
functions and their development toward practical applications require an integrated understanding of their structures, electronic states, and dynamics across multiple hierarchical levels, from isolated superatoms to extended assemblies. Achieving this goal requires researchers engaged in synthesis, characterization of physical properties and functions, advanced measurement, and theoretical calculations to identify critical challenges and engage in discussion across disciplinary boundaries.
This workshop will bring together researchers primarily from the Grant-in-Aid for Transformative Research Areas (A) project “Superatomic Materials.” Professor Manfred Kappes of the Karlsruhe
Institute of Technology, a world-leading researcher in the field of isolated gas-phase clusters, will be invited as the keynote speaker. Participants will discuss the latest advances in the field and its future prospects. In particular, experimental and theoretical researchers will jointly address the fundamental question, “What functions can be realized only with superatoms?” from a broad range ofperspectives. The workshop will also provide students and early-career researchers with opportunities to learn about the forefront of the field and to participate actively in interdisciplinary discussions.
By promoting cross-disciplinary dialogue at the Institute for Molecular Science, where strong research foundations in materials synthesis, advanced measurement, and theoretical chemistry converge, this workshop aims to foster the formation of a new research community and provide momentum for future collaborative research.
On the morning of October 10, a tour of the Institute for Molecular Science (IMS) and UVSOR will be offered to interested participants.
