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

在2012-2013学年，吉田健太教授探索了金多孪生粒子的催化潜力。报道了十面体多孪晶粒子{111}表面的局域应变与CO吸附性能的关系。他成功地将高分辨率电子显微镜应用于实时可视化金纳米粒子的结合和铂单原子的热扩散。他在2012-2013学年发表的论文有：《超小型十面体固有应变纳米金颗粒催化性能的结构起源》，Nano Lett，第12卷，第2027页(2012)，《使用球差校正的透射电子显微镜直接观察Ostwald成熟的初始过程》，J.Electron Microsc.，第61卷，第99页(2012)，以及《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》，第4卷，第1638页(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).
