Structure and Property of Multifunctional Alloy Heterogeneous Nanostructures Hong Yang, University of Rochester, DMR 0449849 Yang group created several platinum alloy nanostructures to study the relationship between structures and electrocatalytic property in oxygen reduction reactions (ORR). The data show that Pt3Ni alloy particles possess strong {111} facet dependent activity using truncated octahedral nanocrystals (J. Am. Chem. Soc., 2010, 132, 4984; see top figure on the right). A morphology-dependent stability is demonstrated in the formation of sub-10 nm Pt nanocubes during a dealloying process (Nano Lett., 2010, 10, 1492). His group also identified a major (kinetic) driving force for the formation of alloy nanowires through the oriented attachment (ACS Nano, 2010, 4, 1501; see the bottom figure on the right). The effective atomic diffusion at the interface upon the collision of primary nanoparticles is shown to be essential.
Structure and Property of Multifunctional Alloy Nanostructures Hong Yang, University of Rochester, DMR 0449849 In 2009-2010, the PI hosted one undergraduate and one high school interns in his research laboratory. Within this funding year, four female students has worked in his group for their graduate degrees (MS or PhD). Two of his students received their PhD and four received their MS degrees between fall 2009 and summer 2010. The PI also served as a career panelist on graduate studies at an AIChE Rochester Chapter meeting. Yang group has established a strong international collaboration program. The PI has two graduate students who are in part supported by the Chinese Scholarship Council. One additional visiting student sponsored by Brazilian government will join his group soon. The PI has also conducted research at Xi’an Jiaotong University in summer 2010. In 2009-2010, Yang group filed three provisional US patents. The PI has served as a continuing symposium chair for ACS Colloid and Surface Chemistry Division on Nanoparticles and Nanostructured Materials (2009-2011).
