摘要：
Smart nanostructures of various topology and different compositions offer exciting opportunities in fundamental studies and advanced technological applications, owing to their unique spatial arrangement, diverse functionalities, superior properties and induced phenomena, against that of their single-component counterparts. The compositions are versatile, ranging from magnetic, semiconductor, inorganic, organic, and metallic to dielectric materials. Notwithstanding the fact that comprehensive studies have been carried out to assemble such elegant nanostructures, multifunctional products of this sort remain in high demand and extensive research is undertaking. We have started research programs to formulate a wide range of multifunctional nanostructures such as nanoparticles and nanowires， focusing on magnetic, photonic and other relevant properties. In this talk, I shall give examples of magnetic-photonic core-shell nanoparticles and barcode nanowires developed either from polymer supported sequential nanoemulsion reactions or alternative electrodeposition, as well as advanced ultrathin films (molecular lubricants and ultrahard surface coating) and briefing on materials design for stealth technology. In particular, the multifunctional nanostructures can simultaneously show well-defined magnetic behavior and exhibit desired optical properties, indicating the amalgamation of both magnetic and photonic functions of the respective components in one entity. Thus, the nanovehicle allows the effective delivery of multifunctionality and successful completion of multivalent purposes in a single mission. This kind of multifunctional magnetic-photonic nanostructures could be of interest in interfacial proximity effects as a result of the special nanoarchitecture configuration and have potential applications in various areas as demonstrated in biomedical applications. In addition, I shall address relevant future research topics on novel perovskite nanomaterials and new integrated multifunctional nanosystems, from syntheses, characterization, mechanism, to potential applications.

报告人简介：
Wu JunHua obtained his B.S. and M.S. degrees from Tsinghua University. During working at Anhui Provincial Engineering Consulting Institute, he was selected by China’s State Commission of Education to study at Max-Planck Institute for Polymer Research, Germany, where he completed his Ph.D. thesis research on shape-persistent polymers and was conferred Ph.D. jointly by University of Mainz, Germany. Then he was invited to join IBM Almaden Research Center as post-doctoral staff member, Seagate Tech as staff development engineer and senior engineer in a start-up located in Silicon Valley. After affiliation with National University of Singapore as senior research scientist and a brief visit to National Tsinghua University in Hsinchu, Dr. Wu was appointed associate research professor and later promoted to research professor at Korea University, tapping potential applications of novel functional nanoparticles, nanowires and quantum dots in (bio)nanotechnology. He has published in the areas of nanoparticles, nanowires, thin films including high density magnetic data storage (surface/interface, molecular lubricants, perpendicular magnetic recording), broadband microwave absorption materials (high performance soft magnetic nanomaterials and carbon nanotubes), polymers, single macromolecules, topochemical photopolymerization of organic thin films, molecular monolayers, glass transition and related transport phenomena, as first author and/or corresponding author in Adv. Mater., Angew. Chem. Int. Ed., Nature Nanotechnology, Macromolecules, Nanotechnology, Appl. Phys. Lett., Langmuir, Mater. Chem. Phys., Gold Bulletin, J. Appl. Phys., Appl. Phys. Express, Solid Thin Films, with 17 patents (USA, Japan, EU and S. Korea) issued.
