The lab uses synchrotron radiation to observe the hierarchical structures of nanomaterials.

AboutAbout the lab
Probing the hierarchical structure of hybrid nanomaterials with synchrotron radiation
The Nishibori Lab uses synchrotron radiation measurements and computational science to investigate the processes by which material structures form.
Materials that are key to energy devices form hierarchical structures across a wide range of scales, from atoms to particles, and these structures determine their properties and functions.
The lab therefore combines spectroscopy and scattering measurements to uncover hierarchical structures across both time and space.
Based on the mechanisms it uncovers, the lab aims to create materials with new functions.
Key terms
- Synchrotron radiation
- Very bright X-rays and light emitted when electrons are bent in an accelerator. It allows detailed investigation of the inside of materials
- Polymer brush
- A structure in which polymer chains stand densely on a substrate surface like the bristles of a brush, leaving nano-sized gaps between the chains
- Zeolite
- A porous material with pores on the angstrom to nanometer scale. Used as catalysts and adsorbents

ResearchResearch themes
By making full use of synchrotron radiation measurements and computational science, the lab clarifies the dynamics of structure formation in a variety of materials, aiming to lead to the creation of new functional materials. The lab believes that to accurately describe how materials exhibit their functions, it is necessary to understand structural changes across a wide range of scales, from atoms to particles.
*Illustrative imagePolymer-Ceramic Hybrid Materials
Polymer brushes, in which polymer chains stand on a substrate, selectively take in molecules and ions of a size matching the spacing between the chains. Using these as templates, the lab attempts to synthesize metal oxides supporting palladium nanoparticles, and follows how the reaction proceeds with X-ray absorption fine structure measurements. The state of the substrate surface is also examined using X-ray photoelectron spectroscopy and first-principles calculations.
*Illustrative imageUnderstanding How Functional Materials Work
Zeolites are porous materials with pores, and replacing framework atoms with other metal atoms changes how they interact with molecules. Heteroatoms isolated within the framework show unique catalytic action. The lab is working to establish methods to analyze their positions and surrounding structures at the atomic level using synchrotron X-ray absorption spectroscopy and resonant inelastic X-ray scattering.
*Illustrative imageMultiscale Analysis of Hierarchical Structures
Organic-inorganic hybrid materials and oxide-ion conductors have hierarchical structures from the atomic to the macroscopic scale, along with motions on corresponding time scales. The lab visualizes these hierarchical structures under heat, light, and stress using synchrotron radiation measurements, and studies the mechanisms of synthesis and functional expression.
