What's New In the Lab?
Five excellent students from our lab will be presenting their projects today at the annual Queen's Chemistry Undergraduate Poster Session. This departmental tradition allows students completing a 4th year project to present their research to friends and colleagues. Come join us today in the 4th floor lounge to hear more about their work!
It was wonderful to host Prof. Jean-Pierre van Helden (IPT Greifswald and University of Greifswald) when he visited Queen's on August 8th, 2017. Before giving a seminar on cavity-enhanced spectroscopy and its application to plasma science, he had a chance to travel through the 1000 Islands on a scenic boat cruise.
Although traditional 3D fluorescence spectroscopy is a powerful analytical technique, it is also notoriously slow, making it inappropriate for kinetic studies. Our paper presents a much faster way to collect 3D fluorescence measurements, using Hadamard 'barcodes' to encode a white light source and the corresponding fluorescence signal. In this work, we used a submersible fiber-probe to measure both the degradation kinetics of spinach extract in acid, and the thermal degradation kinetics of rhodamine B.
