Outline Activities
Understanding and improving the macroscopic properties of materials requires the full knowledge of compositional and structural information at nanoscale. For example, not only the atomic arrangements but also the local chemical composition, bonding and electronic structure play important roles for every type of materials. In our laboratory, we approach materials via evaluation and characterization methods for achieving information of various materials around us, such as ceramics, superconductors, alloys and ferrous metals, to improve their properties for our future.

Their nanostructures were examined in detail at different reduction reaction periods to gain insights into the mechanism of Ag–Pt double-shell formation on Au-core, as well as the competitive role of each reduction reaction. The multishell NPs were found to contain a degree of hollows with the inner surface composed of both Ag and Pt, while the outer surface composed of granular Pt. The coreduction method contributed to the success of increasing Pt surface area that will further benefit catalytic applications of the NPs..

1. 金子 賢治, Three-dimensional nanostructural analysis of artificial pinning in coated conductors by electron tomography, The 15th IUMRS-International Conference in Asia (IUMRS-ICA 2014), 2014.09, In high temperature superconductors, artificial pinning centers (APCs) are intentionally introduced to pin the vortices effectively for compensation of the intrinsic field angle anisotropy and to improve Jc characteristics. APCs have been analyzed via various microscopic methods in detail, many of them are actually in 2D, which does not represent 3D nature of APCs. The nanostructural characterization of APCs in 3D (distribution, morphology, volume, etc.) are of worthwhile for further understanding and improvement of the superconducting properties, and hence for designing of future high temperature superconductors. Electron tomography, a combination of transmission electron microscopy and computed tomography, was therefore applied on APCs to acquire 3D information of them at nanoscale resolution. During my presentation, both three-dimensional electron tomography and actual application of it on artificial pinning centers in various dimension, will be presented..
2. 金子 賢治, Three-Dimensional Electron Tomography for Materials Science and Engineering, The 14th IUMRS-International Conference in Asia (IUMRS-ICA 2013), 2013.12, Currently, there are several “tomographic” methods available to acquire three-dimensional information of materials, and have been applied for various types of materials; three-dimensional atomic probe at atomic resolution, electron tomography via focused ion beam (FIB) method at submicron resolution, and electron tomography via (scanning) transmission electron microscopes, (S)TEM, at a few nanometer resolution. Three-dimensional electron tomography (3D-ET), a technique originally established in the field of life sciences, has been developed and applied for materials science and engineering, which is a useful technique for reconstructing an object from a series of projections acquired by a (S)TEM. In addition, every materials available in the world is actually in 3D and their properties are usually dealt in 3D, so that characterization of materials should also be dealt in 3D at micro- and nano-scale. Recent progress of fully-digitized and automated (S)TEM let us achieve 3D characterization for not only to determine the size and distribution of objects but also to provide information about the 3D morphology.
Five different types of information was achieved by 3D-ET: the morphological information of metallic nanoparticles decorated by supramolecules, the distribution of metallic nanoparticles within catalyst, the crystal habit of CeO2 for catalytic activities, the morphological transformation of GP zones due to plastic deformation, and morphology of precipitates within Al alloy.
