The Surface Chemistry Lab investigates chemical reactions that occur on solid surfaces and pioneers sustainable chemistry. If shining light on a photocatalyst can convert carbon dioxide into fuels and chemical feedstocks, it will be possible to build a system that recycles carbon. Because surface reactions are complex, the lab follows changes in molecules and surfaces in situ using infrared spectroscopy and X-ray absorption spectroscopy. It also traces reaction pathways with isotopes and follows the elementary steps of reactions using density functional theory calculations.

The Structural Chemistry Lab conducts research on the theme of "static and dynamic structural chemistry of disordered systems." The samples it studies include supercritical fluids, liquids and solutions, and ionic liquids. The lab examines the arrangement and fluctuations of atoms with X-ray scattering experiments, and time-related information with spectroscopy experiments using light. By adding the dimension of time to static structures, the lab aims to understand its subjects from more perspectives.

The Organic Reaction Chemistry Lab works on developing reactions that are environmentally benign. The lab develops new methods of molecular transformation that make skillful use of halogen elements such as iodine and bromine. It also takes on the design of catalysts made only of organic molecules, which drive reactions without metals. The lab aims to realize in the flask the precise organic reactions that take place inside living organisms.

The Biological Structural Chemistry Lab conducts research aimed at elucidating the structure and function of biomolecules. In particular, the lab works on structural analysis and functional control of membrane proteins embedded in cell membranes, and applies this work to drug discovery and to understanding how life works. Using X-ray crystallography and cryo-electron microscopy, the lab examines structures in detail down to the molecular level. The lab uses computer simulations to predict protein dynamics and interactions, and also has applications to drug development through industry-academia collaboration in view.

The Biopolymer Chemistry Lab studies the mechanisms by which cells recognize one another, using mammalian cells. The lab aims to clarify, from the standpoint of chemical structure, why egg and sperm bind only to partners of the matching animal species at fertilization. The research also makes use of genetic engineering and immunochemical methods.

The Quantum Chemistry Lab uses theory and computation to clarify the electronic states that determine the properties of matter. Electronic states can be observed with photoelectron spectroscopy, which uses the property that electrons are emitted when light hits a material, and with X-ray absorption spectra. To interpret measured spectra, the lab builds its own computational methods based on quantum mechanics. The lab also incorporates electronic structure calculations using density functional theory and AI, and analyzes material properties on high-speed computers.

The Molecular Spectroscopy Lab uses laser spectroscopy to study how molecules move in liquids and solutions. Many chemical reactions take place in solution, and the motion of the solvent also affects how a reaction proceeds. Using self-built instruments, the lab captures intermolecular vibrations and changes in molecular orientation that occur on timescales from femtoseconds to picoseconds. The lab also works on developing liquids with new functions, such as ionic liquids and deep eutectic solvents.

The Molecular Nano-Physical Chemistry Lab studies the behavior of molecules confined in tiny spaces on the nanometer scale. Inside pores that are only about as large as the molecules themselves, molecules show structures and motions that differ from their usual ones. The lab uses this property to control molecular motion and to discover new reactivity. The lab also pursues research on the design of nanostructures, the development of functional nanomaterials, and topics related to carbon dioxide and clean energy.

The Analytical Chemistry Lab studies methodologies for separating and analyzing substances. The ability of a molecule to distinguish a partner by its size, shape, and electron configuration, and to select it for reaction, is called molecular recognition. For functional substances such as ionic liquids and supramolecular complexes, the lab investigates in detail the reactions in solution and the recognition ability. Based on its findings, the lab enhances reaction selectivity, creates new substances, and applies them to separation and analytical methods.

The Environmental Analytical Chemistry Lab uses X-rays to analyze substances found in Earth's surface environment and in living organisms. The chemical state and crystal structure of an element vary greatly depending on the environment in which the substance formed. Using nondestructive speciation analysis with X-rays, the lab reads the chemical forms of elements and aims to clarify the environments and mechanisms in which substances formed. In the laboratory, samples are sometimes also synthesized through chemical procedures.
