Message from the Department Chair


January 5, 2019: Congratulations to Fred Fregoso (Fischhaber lab) for winning the Eden Award at this year's CSUPERB Symposium! The Eden Award is a competitive honor given to a graduate student in the CSU who has been most successful in presenting his thesis research, in the form of an essay, poster and 10-minute seminar presentation at the symposium.  The field was very competitive this year and Fred should be commended for doing so well to clear convey his complex research results. Well done, Fred!

October 29, 2018: The Andersen lab has published another journal article! The paper, titled "Atmospheric chemistry of hexa- and penta-fluorobenzene: UV photolysis and kinetics and mechanisms of the reactions of Cl atoms and OH radicals" is based on work from former CSUN undergraduates Jonathan Lengkong and Karen Vo, and is done in collaboration with colleagues in Denmark. It is published in the journal Physical Chemistry Chemical Physics.

October 24, 2018: Dr Andersen has published a research paper with graduate student co-author Alex Volkova and undergraduates Dvien Hovanessian and Connor Britzman. The paper, titled "Atmospheric chemistry of (Z)-CF3CH=CHCl: Products and mechanisms of the Cl atom, OH radical and O3 reactions, and role of (E)-(Z) isomerization" has been published in the journal Physical Chemistry Chemical Physics. The article presents an important new CFC-replacement compound which shows interesting reactive E-Z isomerization. (Figure above: depicts formation of the isomer at 10 vs 700 Torr and the energy levels of the radicals.)

October 16, 2018: The CSUN Chem Club has won a green chemistry award from the ACS! The students from the club, along with 12 students from Dr Nguyen-Graff's CHEM 110 class, visited 4th graders at Canoga Park Elementary as part of an Earth Week celebration. One of their activities (and the one for which they won the award) involved measuring what types of materials were best for cleaning up an environmental disaster. The fabrics tested were natural (cotton, linen) and synthetic (nylon, rayon, polyester). The green chemistry component of the activity involved considering the entire energy burden to produce the materials used for remediation. Cotton and linen require energy for cultivation, harvesting and processing into fiber, while the polymers (nylon, rayon and polyester) require energy for synthesis and processing into fiber. The activity included a discussion on the merits and drawbacks of different materials balanced with the materials’ abilities to absorb spilled oil in simulated ocean water. Congratulations, Chem Club!
