Abstract: The identification of novel psychoactive substances is challenging for forensic drug analysts due to the lack of available reference standards. A typical controlled substance identification is made by comparing the mass spectrum of an unknown to that of a reference standard. In the case of newly emerging synthetic designer drugs, there is no reference standard available for comparison. To overcome this, synthetic designer drugs can be classified according to class and subclass using multivariate statistical procedures, such as linear discriminant analysis (LDA).

In the work presented here, compounds from both the tryptamine and phenethylamine classes of synthetic designer drugs were analyzed via gas chromatography-mass spectrometry. Variable selection was performed on the mass spectral data and LDA models were defined for the specified subclasses of drugs. A test set was then introduced to the model to determine the classification success rate. This presentation will demonstrate the applicability of classification models for synthetic designer drugs where a standard method of comparison to a known reference material is not feasible.

Bio: Dr. Amanda Burkhart received her Bachelor of Science in Chemistry from the University of Mount Union in 2014. She then went on to Michigan State University in a dual degree program where she obtained her Master of Science in Forensic Science and Ph.D. in Chemistry. Her master’s thesis focused on the classification of novel psychoactive substances using multivariate statistics while her Ph.D. explored a kinetic-based mathematical model used for the identification of ignitable liquids in forensic fire debris. She moved to Tennessee this summer with her husband and two dogs to start her career at the University of Tennessee at Martin.

Fast or Slow…. Chemistry Makes it Go!

It’s officially that delightful time of year when your students have learned enough chemistry to do demonstrations with fabulous flair and festive finesse!! 

Our local section National Chemistry Week events this year will be flexible.  We will host an in-person, masked chemistry demo show, with BBQ available in a separate room, with outdoor dining.  We will also be airing “live” from the room, and with the ability to broadcast videos submitted by folks unable to attend in person.  What I would love is to have each university SMACS chapter perform a demo (or five!), ideally in line with the theme “Fast or Slow… Chemistry Makes It Go!,” and always with safety and learning in mind. I also hope to encourage each SMACS chapter to challenge their professors to do some demos too — some friendly competition, if you will! Challenge your local scout chapters, high school science clubs, and STEM clubs to join in too – in-person, via zoom, or via the video submission! 

Please send me any videos no later than Wednesday October 20th, by 5pm so I have a little time to compile them. (If the video files are too large to send by email, consider using a dropbox or google drive link.) 

If you’d like some NCW swag for in-person events—mainly the NCW magazines and NCW stickers—send me your mailing address and how many magazines you need, and I’ll put them into the mail today! 

Joyfully, 
Abigail Shelton, NCW Coordinator

Abstract:  The selection of task-appropriate ligands to support transition metal centers is the first, imperative step towards exacting targeted behavior from molecular transition metal complexes. In our research, ligands are used to impart unique electronic properties or to provide steric control at metal ions, that can be exploited for materials and catalysis applications. In this talk, our approach to ligand design will be discussed in the context of electronic and magnetic molecule synthesis, as well as its application to sustainable catalysis.

Bio: Dr. Clark received her B.S. from the University of Illinois at Chicago (UIC) in 2002 and began M.S. work in the same department in 2003. During this time, she performed inorganic chemistry research under the guidance of Dr. Lisheng Cai and Prof. John Morrison. From UIC, she began her PhD at the University of California, Irvine working with Prof. Alan Heyduk exploring redox active ligands. During her graduate studies, Dr. Clark was awarded a fellowship by the American-Scandinavian Foundation as a fellow to Denmark where she spent nearly a year in the lab of Prof. Jesper Bendix at the University of Copenhagen. After finishing her PhD in 2010, she began work as an NIH postdoctoral fellow under the mentorship of Prof. Amir Hoveyda. At the end of 2011, Dr. Clark started her research career as an industrial chemist at Chevron Phillips Chemical Company, LP in the Polyolefins Catalyst and Product Development group. During her 5.5 years at Chevron-Phillips, she was awarded 18 US and international patents. She began as an assistant Professor at the University of Memphis in 2017. Her research uses ligand electronic behavior and/or architecture to control behavior at transition metal centers.

Exploring the Structures and Properties of Strongly Bound Atomic Clusters

Thursday, April 15th @ 7:00 pm

Join Virtually via Zoom
(Meeting ID TBA)

Speaker: Dr. Jonathan T. Lyon, Murray State University

Abstract: Strongly bound atomic clusters are often used as ideal models for the active sites in bulk material. Despite the increased scientific interest in cluster sized particles, open questions remain about the structure, stability, and related properties of specific cluster systems. We present here recent investigations on clusters containing between 2 and 25 atoms. Theoretically, we utilize global optimization procedures to locate new local and global minima candidates. These structures are further optimized with different density functional and ab initio techniques and electronic, vibrational, and internal bonding properties are explored. Complementary experimental matrix isolation infrared experiments currently being assembled will also be discussed. Specific systems presented here include transition metal clusters, doped semiconductor clusters, and metal hydride clusters. Items of particular interest with these systems include novel cluster geometries, cluster size/stability relationships, exohedral to endoheral doped cluster transitions, and hydrogen adsorption energetics.

January 2021 – Message from the Chair

Happy New Year KLS Family,

We certainly share our 2021 resolution contributing to end this pandemic and accomplish many exciting projects. Make 2021 the year YOU get involved! We have a range of volunteer and leadership opportunities available for you to engage with the KLS – from one-time events to programming to awards to executive committee positions, we invite your participation.

I would like to thank Dr. Kevin Miller’s leadership and all volunteers last year despite the global turmoil. I look forward to working with you all this year. The first KLS executive committee of this year met virtually on January 11th and discussed several agenda including tentative spring meetings, grant/report, budget, and committee members for the 2021 term. In January’s virtual meeting (scheduled for 25th), Dr. Grace Eder from Murray State will be presenting 1-3 dimensional polymer materials for sustainability applications. Please join us on 25th at 7:00 PM.

We are planning to have a panel on chemistry careers in the industry for current students and other recent graduates who may have an interest in joining the industry. This panel will be virtual (open to everyone) and involve several recent graduates from our area institutions who are currently in the chemical industry. The event is sponsored in part by an IPG (Innovative Project Grant) from the American Chemical Society. Please contact Dr. Miller or me to share any suggestions.

As part of the “Senior Chemists” project sponsored by the ACS Senior Chemists Committee 2020 Mini-Grant, our four Chemistry senior students interviewed Prof. Harris Fannin, Mrs. Erica Gray, and Dr. Fred Allen. Please visit our KLS webpage and feel free to publicize those amazing interviews!
