Content of research

We have been developing electron microscopy techniques for characterizing nanostructures and functions. In particular, we are aiming to characterize nanomaterials and nanodevices at the atomic scale when they actually exhibit their functions. We have already developed high-resolution environmental transmission electron microscopy that allows us to observe various dynamic phenomena in-situ; for instance, the nucleation and growth of carbon nanotubes from nanoparticle catalysts and the catalytic reaction on the surface of nanoparticle catalysts. These direct observations will be useful for creating and developing novel nanostructures and functions.
