Wei Xu (visiting graduate student, December 2019 - March 2020)
3D printed elastomeric structures under compression as studied by microCT
As a visiting graduate from the research group of Professor Yu Liu at Jiangnan University in
China, Wei carried out research work at Surface Science Western on developing analytical approaches to understanding mechanical responses of 3D printed elastomer structures to compressive pressures using a Zeiss Xradia 410 Versa Micro-CT with an in-situ Deben CT500 compression testing unit. Wei's work provided valuable insights on building pressure sensors and other electric sensors via 3D printing technology. Wei was also trained to operate atomic force microscope and to understand time-of-flight secondary ion mass spectrometry.

Lin 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 Mei 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.

Soheila Naderi-Gohar (graduate student, January 2012 - December 2013)
Enhancing performance of organic thin film transistors via modifications of organic semiconductor and
gate dielectric
Soheila’s work is to look at ways to improve the performance of organic thin film
transistors (OTFTs) by cross-linking the organic semiconductor thin films and by modifying the gate dielectric with self-assembled monolayers of organophosphorous acids. The analytical techniques she uses to understand the modifications include time-of-flight secondary ion mass spectrometry (ToF-SIMS), atomic force
microscopy (AFM). Soheila also works at Xerox Research Centre of Canada in Mississauga for two months each year to fabricate OTFTs and evaluate the device performance including carrier mobility and on-off current ratio.

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.
