To see invisible and
To picture a function of materials
The nature is the most exquisite masterpiece ever composed by nobody and is full of beauty. Since childhood, my interest has been to find the way to create beauty of nature. The telescope showed me the beautiful features; billions of stars, galaxy, planets, comets, etc. The microscope sparked my interest in microscopic beautiful world in nature. However, the impact that struck me most was elaborated nano-world visualized by electron microscopy when I was PhD student.
The beauty of materials is the way the atoms are put together. The behavior of electrons among atoms and molecules governs functions of materials. X-ray is a probe of electrons in materials. Thus, we are now tackling visualization of function of materials by the most brilliant X-ray source, that is, Synchrotron Radiation(SR) as well as X-ray Free Electron Laser(XFEL). Students who have a spirit of challenge to new research field are mostly welcomed to our laboratory.
Professor Masaki Takata
is one of the few scientists who has contributed a lot to both aspects: design for accurate X-ray diffraction experiments and methodology. The many striking achievements for novel materials, such as endohedral metallofullerene, superconductors, metal organic framework, etc.. Published papers are more than 300, including 5 articles in Nature, 6 in Nature sister journals, and 4 in Science.
Introduction of the study
Our research goal is to uncover the precise structure-property relationship in electron density level for various novel functional materials. To achieve the goal, the precise electron mapping in materials is required. Ultra high brilliant X-ray light source is one of the powerful tools since the X-ray is a probe of electron. Our laboratory is connecting to the world-class SR and XFEL facilities, that is, SPring-8 and SACLA. In our laboratory, we are newly developing high resolution SR single crystal/powder diffractometry, SAXS experimental technique as well as coherent X-ray diffraction imaging. The methods will be upgraded to the time resolved and nano-scale beam experiment, that is, X-ray pinpoint structural measurement to observe dynamics and chemical reaction in materials. In addition, application of the leading-edge data analysis technique such as Maximum Entropy Method(MEM), Electrostatic Potential Imaging and Reverse Monte Carlo(RMC) method developed by our group shall allow direct visualization of interaction between atoms and molecules governing function of materials. Our target materials cover novel inorganic materials, soft materials as well as bio materials. We are aiming to create an integrative design paradigm in Materials Science based on the structure-function map visualized by novel light, SR & XFEL.
Message from a senior
Professor Takata is one of the leading materials scientists in the research area of Photon Science. He is dedicated and challenging scientist as well as education-minded researcher. Many young scientists from Asia, US and EU are joining to his laboratory and are enjoying study of the world’s most advanced science in a cosmopolitan interdisciplinary environment. I believe that students can share valuable and fruitful experiences with us.
