Departmental Seminars

The Chemistry and Biochemistry Departmental Seminar Series covers a broad range of fields in the Chemical and Biochemical Sciences. In past seminars, scientists from Academia, Government, and Industry have presented their most recent discoveries and contributions in their respective areas. This Seminar Series offers students and faculty the opportunity to interact directly with other leaders in their specializations and to gain a good overview of the entire range of fields in Chemistry and Biochemistry.

Seminars are held on Tuesdays12:30pm-1:30pm in the Clendenin Building, room 1009 on the Kennesaw Campus (PDF), unless otherwise noted. All are invited to attend.

  • Dr. Janet Arras, Postdoctoral Research Associate, Stollenz Research Group, Kennesaw State University (KSU)
    • “Low Valent Aluminium and Magnesium Compounds: Metalloid Clusters as Snapshots of the very fast Processes of Dissolution and Formation of Metals”
    • ABSTRACT: The first description of a metalloid cluster of a base metal was published 20 years ago: Al77R20 (R = N(SiMe3)2). Before this highlight it seemed to be like a dream to trap intermediates on the way from AlR3 to Al metal because of their thermodynamic favorite decomposition to Al and AlR3 and because of their extremely high sensitivity toward traces of O2 and moisture. In the following decades, the Schnöckel group succeeded in synthesizing a series of metalloid aluminum and gallium clusters with dimensions even on the nanometer scale, since about 30 years ago a highly sophisticated disproportionation and trapping method was invented that allowed the synthesis of highly reactive intermediates: The high temperature molecules AlX/GaX/MgX (X = Cl, Br, I) were obtained at 1000 °C and subsequently trapped at -196 °C as donor stabilized toluene solutions. These donor stabilized toluene solutions of M(I) halides (M = Al, Mg) provide fundamental insights into mechanistic steps of reduction reactions using activated M metal (cf. Grignard reaction). Furthermore, crystallographically determined metalloid clusters are interesting from a technical perspective of potential interest in e.g. batteries.

  • Rio Febrian, Graduate Student in the Bracher Lab at Saint Louis University
    • "Deliquescent Wet–Dry Cycling: A Tale from The Prebiotic and The Professional World"
    • ABSTRACT:  Elucidating the means by which the first functional biopolymers arose on Earth is a major focus of origin-of-life research. In my research, I explore the wet–dry cycling model— a widely regarded means of driving condensation reactions under prebiotic conditions to generate mixtures of prospective biopolymers. A criticism of this model is its reliance on unpredictable rehydration events, like rain storms. In this seminar, I will be talking about the ability of deliquescent minerals—which form aqueous solutions by absorbing water vapor— to mediate the oligomerization of glycine during spontaneous, iterative wet–dry cycles. The deliquescent mixtures can 1) foster yields of oligomerization over ten-fold higher than non-deliquescent controls, and 2) tightly regulate their moisture content. In parallel to my research, I will also talk about how we, as scientists, can apply the systematic, critical thinking approach of the scientific method to business and other everyday complex problems.

  • Gregory Zetzsche, Lecturer at IUT Bordeaux Techniques de Commercialisation, France
    • “Seeing and Smelling the Chemicals in Wine: An Interactive Seminar”
    • ABSTRACT: This talk will include a discussion on skills in “sighting” wine’s appearance, and the scientific link to everything a wine can tell you just by looking at it. An audience-interactive "blind olfaction” activity involving smelling perfume vials of “wine faults” will follow with a discussion of their chemical sources.

  • Dr. Yiman Zhang, Postdoctorate Research Associate at Oak Ridge National Laboratory
    • “Application of layered materials for battery relevant electrochemistry: Case studies of Ag7Fe3(P2O7)4 powder and LiV3O8 thin film materials” 
    • ABSTRACT: In this talk, Ag+-containing iron pyrophosphate is shown to have high power density, where the full theoretical capacity of the material has been achieved. The contrasting redox chemistries of Ag+/Ag and Fe3+/Fe2+ are investigated using in-situ X-ray diffraction and ex-situ X-ray absorption spectroscopy. Second, thin film of layered oxide material LiV3O8 is used as a model system to study the effect of structure and crystallinity on the electrochemical performance of all solid-state thin film batteries. We correlate the cell polarization with both the diffusion coefficient and the Li+ concentration to gain insight on the rate limiting parameters in both insertion and phase transformation reactions.
