| Research Abstract |
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).
