报告题目：Designing Nanohybrids for Energy, Environmental and Biomedical Applications
With unique physical and chemical properties, and high potential for many important applications, nanomaterials have attracted extensive attention in the past two decades. In particular, due to their unique, size- and shape-tunable surface plasmon resonance, plasmonic nanostructures have recently been explored for enhancing the efficiency of solar cells and photocatalysis via improved light scattering, strong near field effect and/or hot electron injection. In another vein, near-infrared (NIR) absorbing and emitting nanomaterials hold high potential in bioimaging for disease detection due to its high sensitivity at the subcellular level and low cost of related imaging facilities.
Combination of different nanomaterials into a single architecture can lead to improved properties/performance or, even better, multifunctional nanoplatforms. In this talk, I will present some of our recent work on the rational design and realization of nanohybrid materials as well as their applications in solar fuel, photocatalysis, biomedicine, etc. [1-9]. For instance, I will give an example on the combination of plasmonic nanoparticles with two-dimensional semiconductor catalysts, showing largely enhanced photocatalytic activity. Another example is about the preparation of multifunctional nanoplatforms compose of multiple superparamagnetic nanoparticles and NIR quantum dots in single particles, which can serve as bimodal imaging probes and bimodal hyperthermia agents. Rational design in order to maximize benefits is highlighted for all these nanohybrids.

Prof. Dongling Ma joined Institut national de la recherche scientifique (INRS) in 2006. Since then, she has been leading the Laboratory of Nanomaterials Synthesis, Characterization and Applications at the center of Energy, Materials and Telecommunications of INRS. Her research interest consists in the development of various nanoparticles (such as semiconductor quantum dots), 1-dimentional and 2-dimensional nanostructures (such as carbon nanotubes and C3N4 nanosheets) and nanohybrids/nanocomposites (such as bimetallic core@shell nanoparticles) for applications in energy (e.g., solar cells), catalysis (including photocatalysis) and biomedical sectors. Concerning her recent work, since 2012 she has published >100 times on nanomaterials research in high quality journals (J. Am. Chem. Soc., Adv. Mater., Adv. Energy Mater., ACS Nano, Adv. Funct. Mater.,Energy Environ. Sci.,Chem. Mater., etc.). She has been invited to talk at prestigious international conferences (such as ACS, ECS, ICMAT & MRS) and government laboratories/universities (such as Argonne National Lab (USA), Princeton University (USA), McGill Uni., Uni. Toronto, with >100 invited talks from 2012 (not including those I declined due to conflict of time)., She serves as an Editorial Advisory Board member of ACS Energy Lett., Sci. Rep., et al., and a panel / committee member for different funding agencies in Canada, European Commission, etc. She is an active Member of the UNESCO Chair in Materials and Technologies for Energy Conversion, Saving & Storage.
Before joining INRS, she was awarded Natural Sciences and Engineering Research Council (NSERC) Visiting Fellowships in 2004-2006 and had worked at the Steacie Institute for Molecular Sciences, National Research Council of Canada for about two and half years (Feb 2004- June 2006). With both B.Sc. degree (in Materials Science) and M.Sc. (in Polymer Materials Science) from Zhejiang University (China), she studied for her Ph.D. in Materials Science and Engineering at Rensselaer Polytechnic Institute in Troy, New York (Sep 2000-Jan 2004).
