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.

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.

Their manuscript has just been accepted for publication in RSC Advances. (This is a new interdisciplinary journal of the Royal Society of Chemistry)
RSC Adv., DOI:10.1039/C2RA20578E
Khaled is a PhD candidate in the MUN Green Chemistry & Catalysis Group. Marcus obtained his results during an NSERC USRA in the group during summer 2011 and Jen held a SWASP position in the group at the same time.

Leeds at Night (by Andrew Roberts, UK)
Chris Kozak visited the School of Chemistry at the University of Leeds last week. He gave a departmental seminar on iron catalyzed reactions being studied by his students at Memorial University. Iron is popular metal to use in metal-catalyzed reactions for organic synthesis because it is cheap and non-toxic.

The St. John’s arts and entertainment magazine, “The Scope”, recently published an article in their on-line edition on some of the work occurring in the MUN Green Chemistry and Catalysis Group. Entitled “Great future in green plastics“, the article by Dave Jerome describes the research on degradable plastics that is being performed by Justin Belanger and other students in the group.

The first paper from Khaled’s PhD research has been accepted for publication by Green Chemistry.
It is called “Hydrolysis of Chitosan Into Levulinic Acid and 5-Hydroxymethylfurfural In Water Under Microwave Irradiation”
It describes our first efforts at converting biopolymers that can be obtained from fishery waste into potentially useful small molecules. This proof of concept will hopefully lead to these natural materials being used alongside agricultural and forestry wastes as the starting point for chemicals with a wide range of purposes including, fuels, agrochemicals, pharmaceuticals and plastics.
Some of the results were obtained in collaboration with Jessica Besaw (NSERC USRA 2010, Kerton group) who Khaled acted as mentor to. Congratulations Khaled and Jess!
Aminopolysaccharides (Chitin) are available in the shells of crustaceans (lobsters, crabs, shrimps). Khaled has shown that valuable 'Platform' chemicals can be made from them
