Dynamic and 3D TEM study of diffusion process of photoexcited electron

吉田健太教授在2012-2013学年研究了金多双粒子的催化潜力。研究了十面体多重孪晶{111}表面局部应变与其CO吸附性能的关系。他成功地将高分辨率透射电子显微镜应用于金纳米粒子聚结和铂单原子热扩散的实时可视化。他在2012-2013学年发表的论文是“关于固有应变超小十面体金纳米颗粒催化性能的结构起源”，Nano Lett。第12卷，第2027页（2012），“利用球面像差校正的透射电子显微镜直接观察奥斯特瓦尔德成熟的初始过程”，《电子显微学》。（2012），“原子结构对催化金纳米颗粒活性和失活的影响”，化学。猫。化学。， Vol.4, pp.1638（2012）。

During the academic year 2012-2013, Professor Kenta Yoshida explored catalytic potential of gold multiple twin particles. Relation between local strain of {111} surfaces of decahedral multiple twin particles and its CO adsorption properties were published. He has successfully applied high-resolution transmission electron microscopy to real-time visualisation of coalescence of the gold nanoparticle and thermal diffusion of platinum single atom. His publication during the academic year 2012-2013 were "On the Structural Origin of the Catalytic Properties of Inherently Strained Ultrasmall Decahedral Gold Nanoparticles", Nano Lett., Vol. 12, pp.2027(2012),"Direct observation of the initial process of Ostwald ripening using spherical aberration-corrected transmission electron microscopy", J. Electron Microsc., Vol.61, pp.99(2012) and "On the effect of atomic structure on the activity and deactivation of catalytic gold nanoparticles", Chem. Cat. Chem., Vol.4, pp.1638(2012).
