Group membersLin Du (visiting graduate student, September 2016 - December 2016)
Surface analysis of controlled-release drug delivery systems
Lin carried out research work at Surface Science Western as a visiting graduate from Professor Tu's group at Jinan University in China. During her visit, Lin worked on developing a drug delivery approach using alternating polymer and drug layers spin-coated on a substrate, which is an extension of her work on a controlled release drug delivery system using a biodegradable copolymer and an antibiotic. At Surface Science Western, she used atomic force microscopy to examine the morphology of each layer and time-of-flight secondary ion mass spectrometry to depth profile the structure of the polymer and drug layers.

Enhancing performance of organic thin film transistors via modifications of organic semiconductor and gate dielectric
Horace Wu (summer student, May 2013 - August 2013)
Self-assembled monolayers for hydrophobic AFM probes
Horace worked in developing a dip-coating technique for depositing SAMs on hydrophilic surfaces. This method was applied to modify AFM probes to enhance their chemical stability and longevity. He also helped a number of students in their projects by providing AFM imaging analyses on their polymeric films.
Kevin Huang (summer student, May 2012 - August 2012)
Developing AFM applications and techniques for organic thin films
Kevin’s work was to use AFM to image morphology, measure adhesion force and evaluate scratch resistance of organic thin films including organic semiconductors. He studied dispersions of carbon nanotubes (CNTs) in a polymer matrix towards electronic device applications. His work contributed to understanding appropriate combinations of CNTs nanotubes and polymer for the best dispersion of CNTs in the polymer composite.
Some of the students were supported by a University Partnership Committee Funded Research program from Xerox Research Centre of Canada and an NSERC CRD project.
