Interaction Functional Materials Lab
Machine-translated · View original
The lab creates materials and devices for collecting the chemical information carried by molecules.
AboutAbout the lab
Electronic materials that interact with people and the environment
The Interaction Functional Materials Lab (Nagashima Lab) studies electronic materials and devices that actively interact with the outside world.
The chemical information carried by molecules in our surroundings is thought to be far richer than physical information such as heat, force, light, and sound.
Conventional electronic materials have been sealed off from the external environment to prevent degradation, but collecting chemical information requires contact with the outside.
The lab designs, at the atomic and molecular level, materials and devices that combine robustness with the ability to distinguish molecules.
Key terms
- Molecular recognition
- A mechanism that distinguishes and captures only the target molecule from among many molecules
- Nanomaterial
- A material with an extremely fine structure, about 1 to 100 nanometers in size
- Carbon nanotube
- An extremely thin substance in which carbon atoms form a hexagonal network rolled into a tube

ResearchResearch themes
To collect and make use of chemical information, the lab designs electronic materials and devices that combine robustness with molecular recognition at the atomic and molecular level. It pursues interdisciplinary science spanning materials, devices, and data.
*Illustrative imageSeparating carbon nanotubes by structure
Carbon nanotubes, one type of nanomaterial, change properties such as color through quantum effects when structural features such as diameter change. As-synthesized nanotubes contain a mixture of structures and are unsuitable for many applications, so the lab uses separation and purification techniques to extract single-structure nanotubes, aiming at device applications.
*Illustrative imageTransition metal dichalcogenide nanotubes
Nanotubes made by rolling transition metal dichalcogenides into tubes change properties such as color with diameter and composition, through strain and light-confinement effects. The lab develops synthesis techniques that control structure and composition, and explores functions that exploit the strain arising from the tubular shape.
