Abstract: Synthesis of interfaced nanoparticle dimers made of asymmetric compositions (i.e., interfaced heterodimers) is challenging because it is difficult to manipulate the nanoparticles’ surface properties to control the assembly and/or growth of different nanoparticles. In this presentation, the general principle will be first introduced for the formation of interfaced heterogeneous dimers made of different inorganic nanodomains that exhibit either crystalline or amorphous structures. Although many different combinations are possible, the heterodimers containing plasmonic components (e.g., gold and silver nanodomains) will be focused in this presentation to highlight a number of synthetic methods and unique properties observed in heterodimers. Due to the direct contact between the two components in each interfaced dimer, strong coupling between them are expected to induce new properties that cannot be observed from any individual components. Biosketch: Prof. Dr. Yugang Sun obtained his B.S and Ph.D degree from University of Science and Technology of China (USTC) in 1996 and 2001, respectively. He then worked as a postdoctoral fellow with Prof. Younan Xia at University of Washington and Prof. John A. Rogers at University of Illinois at Urbana-Champaign. In 2006, Dr. Sun joined the Center for Nanoscale Materials at Argonne National Laboratory (ANL) to start his independent research career. Starting 2016, he will move to the Department of Chemistry at Temple University. He was listed in the top 100 chemists (#62) and top 100 Materials scientists (#5) analyzed by Thomson Reuters in 2011. He was again selected as a highly cited researcher in both Chemistry and Materials Science in 2014. His research is centered in the design/synthesis of hybrid nanostructures as well as investigation of novel properties of the synthesized nanostructures in the context of nanophotonics, photocatalysis, sensing, and energy storage/conversion.
