Chris presents his poster in Toulouse
Chris, Fran and Justin attended this international conference during the past week. We saw lots of great talks and presented our posters alongside many other delegates……we also ate far too much good food and drank too much wine thanks to the generous hospitality of our hosts. Next time (July 2014) the conference is being held in Ottawa, Canada. The website for the next ISHC is found here.

Check out the following link on the Green Chemistry journal’s site to read about Fran’s author profile, how she became interested in green chemistry, and how she very well could have become a singing sensation instead (without having to go on “Idol”!)

A paper describing the collective work of three undergraduates in the Green Chemistry and Catalysis Group has been accepted for publication in the journal Polyhedron. The work was done by Lisa Saunders (who is headed for grad school at Queen’s U.) during a USRA project, Michelle Pratt during a MUCEP work term (who is starting at MUN medical school this September) and Sarah Hann, who was employed as a summer research assistant in the group and is currently a med. student at MUN.
The paper is entitled: “Structural Variations in the Coordination Chemistry of Amine-bis(phenolate) Cobalt(II/III) Complexes” and should appear on-line shortly. Thanks to Lisa, Michelle and Sarah for their hard work on these capricious cobalt complexes, and to Andreas Decken (UNB Crystallography Service) and Louise Dawe (C-CART XRD lab) for their expertise.

Thank you and congratulations to Marcus Drover (Mr. April) for having his entry selected for inclusion in the first calendar prepared by the inorganic division of the CSC. It is available for download in pdf format, if you click HERE! We hope that future students will submit entries and also be selected for inclusion – what a great artistic way to tell the world about your chemistry research!

Chris, Fran, Khaled and Nduka have been enjoying the science and Albertan hospitality at the CSC
Chris and Fran spoke in the metal-mediated polymerization symposium organized by Mike Shaver and Paul Hayes. Nduka presented his poster in the same symposium on Sunday evening and Khaled presented his poster in the Industrial division on Monday night.
Thanks to all the organizers and volunteers for a fantastic meeting.

Chris was interviewed on the Rogers TV St. John’s local television program “Out of the Fog” yesterday. The segment discussed the problems with currently used plastics and how biodegradable and renewably-sourced plastics, such as those being investigated in the MUN Green Chemistry Group, may be able to address some of the long term environmental issues.

Congratulations to Khaled on his Departmental Seminar yesterday.
He received two bits of exciting news today:
1) His research on the production of levulinic acid and 5-hydroxymethylfurfural has made it into the top ten most accessed articles in Green Chemistry for April 2012.
2) His full paper on the formation of an amidofuran from N-acetyl D-glucosamine has been accepted for publication in the prestigious journal ChemSusChem. (Impact Factor, 6.3). In this work, we note that the presence of main-group elements (B & Cl) in your feedstock can have a significant effect on the reaction outcomes.
Also, congratulations to Linda (one of our DAAD RISE summer researchers who visited our group in summer 2011) – who is a co-author on the ChemSusChem paper.

Prof Art Ragauskas has been organizing an online poster celebration to celebrate Earth Day since 2010.
This year our group took part for the 1st time, as Khaled submitted a poster on his research surrounding the hydrolysis of chitosan. It is available here.
Thank you to Khaled for sharing his research with a wider audience and to all those involved in organizing this event.

A second paper by group members has been accepted today for publication. This time in Dalton Transactions.
The paper is called: Ring-opening polymerization of ε-caprolactone by lithium piperazinyl-aminephenolate complexes: Synthesis, characterization and kinetic studies
Dalton Trans., DOI:10.1039/C2DT30276D
Nduka is a PhD candidate in our group and Christian was a visiting student from Germany who joined our group last summer on a DAAD RISE scholarship. They worked really hard to get all the kinetic data and the MALDI-TOF spectra presented in this paper. Thanks also to Louise for the two structures included.
