Work Experiences
From Dec. 2014 to present, Lab manager , North Dakota State University
From 08/2009 to 09/2010, Study on polymer (PBT)-clay nanocomposite materials for protection of flexible electronics ( EPSCoR program) , Drung this project, I successfully prepared PBT-organically modified montmorillonite nanocomposite with slightly reduced crystallinity and improved nanomechanical properties through intercalation, hydrogen bonding and ionic interactions between the constituents; Published one paper as coauthor.
From 09/2000 to 03/2004, Preparation and characterization of absorbable hemostatic oxy-cellulose for medical use, Key Subject Project of Committee of Education, Shanghai (NO.B990704) , During this project, I used an oxyl radical system to selectively oxidize regenerated cellulose to acquire a biocompatible and biodegradable material which can be used to absorb leaking blood and clot bleeding during surgery. The experiments were statistically designed; and the structures of the products were ascertained by NMR, FTIR, and XRD characterizations. Published 3 journal papers and 1 conference paper.
From 09/2010 to 12/2014, Study of human cortical bone undisturbed and with osteogenesis imperfecta , Advanced the understanding of ultrastructure, molecular differences and mechanical properties of human bones from natural nanocompostite aspect by proficiently using FTIR, AFM, SEM, XRD, and nanoindentation methods
From 12/2014 to present, Polyurethane Pipeline Coatings (collaborate with Northwest Pipe company) , Studied polyurethane pipeline coatings' color, gloss, thickness, and electrochemcial impedance change after natural outdoor exposure in Florida and Texas as well as indoor QUV exposure.
