   2013.11 Young Thousand Talents

   2013  Hundred Talent Program Professor, Institute of Chemistry, CAS

Postdoctoral Fellow, University of Florida (Gainesville, FL) 04/2009 –03/2013

• Synthesize CdS/CdSe nanorods and then achieve a nanorods assembly that can be prepared with large dimensions with a good lateral alignment of the nanorods. Achievement of such well aligned nanorods assemblies could permit construction of large scale polarized LEDs, solar cell and other devices with polarization ratios approaching or exceeding the polarization ratio of the individual nanrorods that form the assembly. From the calculation, the nanorods assembly matches the minimums surface energy

• Synthesize mono-dispersed sphere and cubic shape Fe3O4 magnetic nanoparticles, design the nanoparticles assembly with different shapes by controlling the reaction condition, and study the shape-dependent therapeutic effect to cancer cells.

• Study the phase transition of quantum dots and magnetic nanoparticles under high pressure, and achieve high density materials (rock salt) that are not general obtained under atmospheric pressure.

Postdoctoral Fellow, Rensselaer Polytechnic Institute (RPI) (Troy, NY) 02/2008 – 04/2009

• Improve thermoelectric properties of low-bandgap semiconductor based on nanotechnology. The research includes synthesis, characterization of the nanoparticles (Sb2Te3, Bi2Te3, Sb2Te3/Bi2Te3) with different shape including sphere, belt, and honeycomb, as well as their thermoelectric properties on the device.

Research Assistant, Changchun Institute of Applied Chemistry (Changchun, China) 09/2002 – 12/ 2007

•The application of noble metallic nanomaterials (gold, silver and platinum) in surface-enhanced Raman scattering (SERS), heterogeneous biocatalysis, superhydrophobic surface and electrochemistry. The various shapes of gold nanoparticles and assemblies including sphere, rod, plate, flower and tube were applied to detect shapedependent properties of SERS spectroscopy, fabricate renewable SERS substrates, and transform normal cloths into superhydrophobic surfaces.

• Study the electron transfer between the small biomolecules (amino acid) and gold nanoparticles, the extra electron will cause the fragmentation of gold nanoparticles.

• The second project is the functionalization of carbon nanotubes (CNTs). The paralleled CNTs were aligned on electrodes with electrochemical measurement, assembled with noble nanoparticles occurring not only in solution but also on solid surface, and used to improve the heterogeneous enzyme catalytic reaction for the biosensor.
