Quantum Chemistry Lab

AboutAbout the lab

Changing the number of atoms one by one to explore the properties of matter

The Quantum Chemistry Lab focuses on clusters, extremely tiny particles with a precisely defined number of atoms, and aims to open a new phase of nanomaterials science.
The lab explores the physical and chemical phenomena involving clusters from the perspective and with the research methods of physical chemistry.
Its research methods include ways of generating clusters using mass spectrometry, methods for tracking chemical reactions, and spectroscopic methods using lasers and synchrotron radiation.
In education, the lab centers on the concepts of quantum chemistry and aims to help students develop the ability to understand the makeup of matter and its properties from a microscopic perspective.

ResearchResearch themes

The lab investigates the physical properties and reactivity of matter from a physical chemistry perspective, through clusters: extremely tiny particles with a precisely defined number of atoms. It also aims to open up a science that bridges the microscopic world of atoms, molecules, and clusters with the macroscopic liquid and solid phases.

Clusters that change with a single atom↗

Adding or removing just one atom can dramatically change physical properties and reactivity, and the discovery of new materials that go beyond conventional wisdom is expected. In catalysis, clusters that replicate the nanostructures serving as active sites can lead to an understanding of the essence of reactions and to the design of new materials.

Changing size one atom at a time↗

The lab captures size effects by varying the number of atoms (the size), investigates physical properties and reactivity, and also works on creating new materials. It uses a generation method that controls size with single-atom precision through mass spectrometry, methods for tracking chemical reactions, and spectroscopic methods using lasers and synchrotron radiation.

Bridging from atoms to liquid and solid phases↗

The lab regards the process by which the properties of microscopic matter extend to phenomena in the macroscopic realm as a fundamental problem of materials science. It works on topics such as the development of magnetism in transition metals, the development of surface plasmon resonance in the optical response of electrons in metals, and the solid–liquid phase transition dynamics of tiny droplets.
