Summer Research and Publications

It’s summertime, which is prime research time here in the Chemistry and Biochemistry department. Many faculty are working on research with students, writing manuscripts, or traveling to conferences to present their research findings.

With over a month still left in the summer, there is still time to get research work done before we focus again on teaching (although research continues during the school year too!).

Summer is also a good time for new students to join a lab so that they can focus on learning new techniques before class starts in the fall. If you are interested in joining a research lab this summer, read over the professor bios on the department page. Find a professor whose research is interesting to you and reach out to them via email to see if and when they are accepting students. A good thing to do is read recent publications from the professor’s lab to understand what kind of research they do.

Speaking of recent publications, we highlighted some in a previous post this year, but there are other recent publications we wanted to mention too:

Dr. Wolbach had a book chapter published on her Geochemical research

Brief Overview of the Younger Dryas Cosmic Impact Datum Layer 12,800 Years Ago and Its Archeological Utility
Malcolm A. LeCompte, A.Victor Adedeji, James P. Kennett, Ted E. Bunch, Wendy S. Wolbach, and Allen West
In: Early Human Life on the Southeastern Coastal Plain (eds. A.C. Goodyear and C.R. Moore). Florida Museum of Natural History: Ripley P. Bullen Series, University of Florida Press, 155-174 (2018).

Dr. Kharas published a paper in January with several undergraduate co-authors:

Synthesis and styrene copolymerization of novel trisubstituted ethylenes: 1. Alkyl ring-substituted isopropyl 2-cyano-3-phenyl-2-propenoates. R.L. Pride, C.J. Anderson, M.S. Aelion, O.S. Barry, M. Berry, E. Blankemeyer, M.M. Bolton, A. Bravo, I. Chae, C.M. Franco, M. Galindo, W.S. Schjerven, G.B. Kharas. J. Macromol. Sci. 55 (4) 355-361(2018).

DePaul Research Highlighted in ACS Special Issue

The ACS journal Organometallics recently published a Special Virtual Issue focusing on Undergraduate Research in Organometallics. Two DePaul Chemistry and Biochemistry faculty members, Dr. Paul Vadola and Dr. Kyle Grice, had their papers included in this Special Virtual Issue!

According to the website of the special issue,

“This Virtual Issue features 24 organometallic chemistry papers from research groups at Primarily Undergraduate Institutions (PUIs) published in four core journals from 2014-2018: Organometallics, Inorganic Chemistry, Organic Letters, and The Journal of Organic Chemistry. The PUI researchers featured here represent a broad spectrum of institutions across the U.S. and Canada, career levels of faculty, and areas of interest. But they all share the common purpose of the pursuit of high-quality research with undergraduates”.

“It’s clear from these highlighted reports that PUI researchers strive to maintain a presence in emerging frontier areas of organometallic research”.

“As the guest editors noted: “The research featured in this Virtual Issue is a testament to the high-level work that can be performed with undergraduates. …Research for undergraduates is often a transformative experience, providing a natural incubator for the next generation of organometallic chemists””.

Congratulations to Dr. Vadola and Dr. Grice and their students for having their work highlighted! Way to go DePaul Chemistry and Biochemistry undergraduate researchers! You can learn more about the research being performed by Drs. Grice and Vadola, as well as our other faculty, by visiting faculty bio pages.

Here are the citations to the papers that were highlighted:

Publications from Faculty and Students

Research from the Department of Chemistry and Biochemistry has produced several articles in several major journals in recent months. Undergraduate and graduate student coauthors were prominently involved in many of the studies.

publications-2

In December of 2017, Prof. Kyle Grice and five DePaul student coauthors published a paper in New Journal of Chemistry studying the behavior of drug molecules, in collaboration with colleagues at Rosalind Franklin University and North Carolina State University.The research team used NMR, reactivity testing, absorbance spectroscopy, fluorescence spectroscopy, X-Ray crystallography, and computational methods to study the compounds. They determined that a C-S bond was very weak because of the favorable formation of a carbocation upon cleavage. This result may explain some of the biological activities of these molecules as well.

Prof. Paul Vadola and five DePaul students published an article in the Journal of Organic Chemistry in January reporting a catalytic redox-neutral method for the synthesis of spirolactams, proceeding through the dearomative spirocyclization of N-aryl alkynamides. They were able to achieve selective spirocylcization with 35-87% yields and broad substrate scope.

Profs. Caitlin Karver and Carey Southern published a collaborative paper in February 2018 in the journal Analytical Biochemistry , with four DePaul student coauthors. They were able to develop a new assay for monitoring inflammatory caspase activity, relying on energy transfer between a tryptophan coumarin amino acid side chains. This methodology will allow for C-terminal amino acids to be included in peptide substrates. They were able to find activity differences with minor sequence modifications on the C-terminus with one enzyme, and will be able to develop a substrate specificity/selectivity pattern for all of the inflammatory caspases in the future.

Profs. Kyle Grice  and Graham Griffin published a collaborative paper in the Journal of Physical Chemistry A in March of 2018, along with four DePaul student coauthors. Their study reveals the solution phase structure, electronic structure, and electronic dynamics of a metal-ligand complex that has applications in OLEDs and other organic electronic technologies.

Profs. Wendy Wolbach and Timothy French were co-authors on two papers recently published on a significant bio-mass burning episode 12,800 years ago (a cosmic impact caused a really really big fire!). Both papers were published in the Journal of Geology (second paper) and the articles got some press coverage as well!

Congratulations to all of the authors, we are very proud of their hard work and great achievements!

DePaul Faculty Go to #ACSNOLA

Part of doing science is communicating your results in both written and oral form. Towards this end, DePaul faculty travel to conferences to present the work they’ve done with students here in the department of chemistry and biochemistry.

This spring break, The American Chemical Society has it’s 255th National Meeting and Exposition in New Orleans.

Both Dr. Grice and Dr. Vadola will be presenting, and a poster by one of Dr. Griffin’s Collaborators is also being presented.

Dr. Grice is giving a talk on carbon dioxide reduction research performed with DePaul undergraduates. Here’s the abstract. 

Dr. Vadola is giving a talk on gold-catalyzed C-C coupling reaction research he has been performing with DePaul undergraduates. Here’s the abstract. 

Here’s the abstract to the poster by Dr. Griffin’s collaborators. Dr. Grice’s collaborator at RFUMS is also giving a poster based on the DePaul-RFUMS collaborative work, see here.

If you want to hear about what happens at the ACS meeting, you can follow the hashtag #ACSNOLA on twitter.

Also, if you are a student researcher and want to go to a conference, you should definitely find a way to do so! They are great experiences for learning about science, practicing science communication, networking with peers, and learning about potential career information. Talk to your research advisor well in advance and you might be able to find a way to fund the trip. The ACS Great Lakes Regional Meeting 2019 will be in Lisle, IL, and will be much cheaper than a ACS National meeting, so it should be fairly easy to attend. There are also many other options out there, so keep your eyes out and talk to your research advisor!

Undergrads, Present your Research at CAURS!

 

CAURS

Every spring, the Chicago Area Undergraduate Research Symposium (CAURS) is held at a location in Chicago and undergraduates from DePaul, IIT, U of Chicago, Northwestern, Loyola, and Roosevelt Universities present posters and talks.

Here’s the website for CAURS.

This year, we are delighted that CAURS will be held at DePaul in our student center. The event is all day April 15th, 2018. Put it on your calendar!

It’s free and everyone is welcome, but registration is required for all attendees. Undergraduates, if you would like to present, talk to your research advisor and then submit your information by March 31. If you would like to go and see the posters and talks but do not want to present, register as an observer. Faculty and graduate students can register to be judges if they would like to get involved beyond just being an observer.

Students get valuable experience presenting their work, networking with peers, and seeing what kinds of research is being done by undergraduates around the Chicagoland area. In addition, several awards are given out for the best posters and talks.

We hope to see you all there!
