Abstract：

In this talk, I will summarize the recent research on synthesis, characterization and applications of low-dimensional nanomaterials in my group [1]. I will introduce the synthesis and characterization of novel low-dimensional nanomaterials, such as 2D graphene-based composites [2] including the first-time synthesized hexagonal-close packed (hcp) Au nanostructures on graphene oxide [3] and the epitaxial growth of Pd, Pt and Ag nanostructures on solution-processable MoS₂ nanoshees at ambient conditions [4], single- or few-layer metal dichalcogenides nanosheets [5], and large-amount, uniform, ultrathin metal sulfide nanocrystals [6]. Then I will demonstrate the applications of these novel nanomaterials in chemical and bio-sensors [7], solar cells [8], water splitting [9], electric devices [10], memory devices [11], conductive electrodes [7b, 8, 10a, 11a,b, 12], etc.

Brief CV

Dr. Hua Zhang obtained his B.S. and M.S. degrees at Nanjing University in China in 1992 and 1995, respectively, and completed his Ph.D. with Prof. Zhongfan Liu at Peking University in China in July 1998. He joined Prof. Frans C. De Schryver’s group at Katholieke Universiteit Leuven (KULeuven) in Belgium as a Research Associate in January 1999. Then he moved to Prof. Chad A. Mirkin’s group at Northwestern University as a Postdoctoral Fellow in July 2001. He started to work at NanoInk Inc. (USA) as a Research Scientist/Chemist in August 2003. After that, he worked as a Senior Research Scientist at Institute of Bioengineering and Nanotechnology in Singapore from November 2005 to July 2006. Then he joined the School of Materials Science and Engineering in Nanyang Technological University (NTU) as an Assistant Professor. On March 1, 2011, he was promoted to a tenured Associate Professor. On Feb. 1 2012, he was appointed as the Head of Division (Materials Science).

He has published 3 invited book chapters, 47 patent applications (including 8 granted US patents), and over 240 papers, among which 212 papers were published in the journals with IF>3 (including 68 papers published in IF>10 journals and 49 papers published in 7<IF<10 journals). Some of his papers have been published in Science, Nat. Chem., Nat. Commun., Chem. Soc. Rev., Angew. Chem. Int. Ed., Adv. Mater., J. Am. Chem. Soc., Nano Lett, ACS Nano, Adv. Funct. Mater., Chem. Sci., Small, etc. Based on Web of Science on 9 Aug., 2013, the total citation of his papers is over 7,300 with H-index of 45. He has been invited to give more than 130 Keynote Lectures or Invited Talks in many international conferences or universities and serve as Session Chair. He has organized several international conferences and served as Symposium Chair. He is an Associate Editor of International Journal of Nanoscience (2007-), sits on the Advisory Board of Chem. Soc. Rev. (2012-) and Nanoscale (2012-), the Editorial Advisory Board of Small (2012-) and Nanofabrication (2012-), the Editorial Board of Carbon (2013-) and NANO (2007-), and the International Advisory Board of ChemPlusChem (2012-). He is also one of the members of the Advisory Committee of IOP Asia-Pacific (2010-). He got the SMALL Young Innovator Award (2012) and Nanyang Award for Research Excellence (2011).

Dr. Zhang’s research is highly interdisciplinary. His current research interests focus on synthesis of two-dimensional nanomaterials (graphene and transition metal dichalcogenides) and carbon materials (graphene and CNTs) and their applications in nano- and biosensing, clean energy, etc.; controlled synthesis, characterization and application of novel metallic and semiconducting nanomaterials; scanning probe microscopy; lithography-based fabrication of surface structures from micro- to nanometer scale; self-assembly and self-organization of nano- and biomaterials; self-assembled monolayers; etc.
