Dylan J. Shields

My research in Professor Gudmundsdottir’s laboratory is focused on elucidating solid-state reaction mechanisms and how molecular energy can be converted into mechanical energy. By understanding how to convert molecular stress into mechanical energy, new classes of smart devices can be formulated for use in sensors or energy harvesting applications.  I am proficient in using transient spectroscopy on nanosecond timescale in solution and the solid state, and familiar with picosecond Pump-Prove spectroscopy (IR and UV). I am efficient in synthesis of organic compounds, as well as isolating and characterizing photoproducts.  In addition, I can readily preform DFT calculations and use the calculations correlate with experimental results. Finally, I have experience in obtaining and solving X-ray structures. ​

Upasana Banerjee

Current Research:

My research in Dr. Gudmundsdottir group is focused on physical organic chemistry, more precisely studying the mechanism of photoreactions in solution, solid-state and cryogenic matrices, with special emphasizes on determining the forces that cause crystals to be photo-responsive upon exposure to light. I am skilled in organic synthesis, transient spectroscopy such as laser flash photolysis, matrix isolation, and EPR spectroscopy. Furthermore, I am proficient in supporting my reactions mechanism with density functional theory calculations. My research also focuses on photoresponsive organic crystals. I have investigated various underlying factors such as crystal packing, intermolecular interactions, size and quality of the crystal and the intensity of the incident light to understand how these factors control the dynamic behavior of organic crystals, to develop a bridge between the structure and function of photoresponsive organic crystals.

Current research:

My present work is focused on using flow chemistry techniques to make flavanoid derivatives. Flavonoid derivatives exhibit diverse biological activities which are beneficial to human health. Photochemical method is a sustainable way to make this biologically active compounds from hydroxy chalcones. My focus is to apply the continuous flow method in the photochemical synthesis of flavonoids to make it more sustainable. Also, I am interested in studying the photochemical mechanism for the formation of flavonoid derivatives from hydroxychalcones.

DeAnte Judkins

At the University of Cincinnati, DeAnté obtain his BSc ACS certified in 2014. Afterwards, DeAnté proceeded to the industry where he worked at Tedia as a R&D Chemist. There is where he developed many procedures to purify raw materials formulating high purity solvents and also developed different methods to analyze the solvent’s purity using instrumental analysis.

 

Today, DeAnté is currently a PhD Candidate at the University of Cincinnati where he is training to become a Physical Organic chemist with a focus in Photochemistry. In his research, DeAnté is studying the photo-reactivity of nanocrystals and solutions of Azide-Naphthoquinone derivatives, where solvent trapping occurs and polymorphic behavior is displayed. To elucidate the reaction mechanism upon photolysis, many in-lab techniques are used such as products isolation, cryogenic matrices, laser flash photolysis, x-ray crystallography, ESR spectroscopy, and all the former instrumental analysis techniques. As a Photochemist studying reaction mechanisms that incorporates excited states, high-spin nitrenes, and other reactive intermediates, DeAnté compliments his experimental data with computational analysis. Having DFT Calculations assist his instrumental data, he is able to further identify the portion of the mechanisms that occurs on the nanosecond scale as well as the intermediates and products. In his research he will be displaying how the crystal lattice affects the photodynamic behavior of his Naphthoquinone crystals; one Naphthoquinone derivative shows to be jumping crystals and the other derivative exhibits polymorphic behavior upon crystallization where the crystal lattice alters the photodynamic effect from jumping to bending.
