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.
