What's New In the Lab?
Five of our members graduated with their B.Sc. this past week; a big congratulations to Sarah Denotter, Emily Groper, Cameron Reid, Andrew Williams and Omar Yaman. Cameron Reid (pictured) also picked up some extra hardware, earning both the Medal in Chemistry and the Prince of Wales Prize, given to the top chemistry graduate and top B.Sc graduate overall at Queen's.
Our laser booth at the Science Rendezvous this year was a big hit! Featured here is a NIR camera, laser fountain and the ever-popular fiber optic lamp. Our volunteers from left to right: Travis Ferguson, Omar Yaman, Will Day, Cameron Reid, Andrew Williams, Adam Bernicky, Amy MacLean, Peter Loock, Si Jia Li.
A new article co-authored by former graduate students John Saunders, Hao Chen, Weijan Chen and undergraduates Chris Brauer and McGregor Clayton, describes the application of a new interferometric refractometer to one of the most ubiquitous polymers, i.e. silicone. In the article we use a new model based on the Lorenz-Lorentz equation to quantify the amount of organic vapours in the PDMS film and can even characterize the polymer restructuring that occurs when a guest molecule enters the polymer.
