ACS Chicago

The national meeting of ACS occurring in the Midwest was an opportunity not to be missed!  Charley presented a poster and our researchers spent two days exploring the symposium.

Welcome back Dr. Rachel Beltman

We have the honor of welcoming back Rachel Beltman.  She started with us as an intern in the summer of 2017.  From there, she attended graduate school at Wayne State University and was awarded a PhD in Biochemistry this summer.  She is back to help us out with some compounds of interest.  Her contributions are much appreciated.

How it started (2017)…                      How it’s going (2022)….

Rachel’s time back with us was short but sweet.  Congratulations on your new position at Gentex.  Your future is bright!

Charley Hengesbach

Charley started with the OESLab the summer of 2021 and stayed through the year.  She did great research and increased our knowledge of our target compounds immensely.  She also did an amazing job working with five new interns this summer.

Charley is continuing to work at MSUBI, but she has moved to the pilot plant area where she will be a Process Engineer.  This is great because we still get to see her every day.  Thanks Charley!

Synthesis of Novel Pyridinium Porphyrins for Electrochemical Energy Storage

Organic Energy Storage Laboratory at Michigan State University Bioeconomy Institute 

Porphyrins have applications in nonaqueous redox flow batteries (RBFs) as bipolar redox-active materials and in solar photovoltaic cells as light absorbers and transfer agents. Use of porphyrins in RBFs has been limited by poor reversibility in the second electron redox reaction and low solubility. Pyridinium porphyrins have the potential to improve on these limitations for RBFs. Pyridinium porphyrins may also be viable for photochemical electron cascade in solar photovoltaic cells due to their increased electron-hole pair separation. Zinc-metalated and free base pyridinium porphyrins were obtained by reaction of aminophenyl porphyrin with pyrylium in a multistep synthesis. Redox potentials were characterized by cyclic voltammetry. Here, we present a synthetic pathway for pyridinium porphyrins and ongoing analysis of pyridinium porphyrin usefulness in electrochemical energy storage. 

Thanks Evelyn!  It was a great summer with you.  Enjoy Ann Arbor and UMich.

Novel Linked Ferrocene Donor-Acceptor Compounds for Use in Symmetric Non-Aqueous Redox Flow Batteries

Traditional aqueous redox flow batteries are common vessels used in energy storage, but their cell voltage is limited by the potential window of water. Shifting to non-aqueous cells provides a larger potential window and a wider range of active materials that can be utilized. Additionally, employing bifunctional molecules helps mitigate the cost and environmental impact of such cells. Novel linked ferrocene donor-acceptor compounds show great promise for use in these non-aqueous cells based on their physical properties, including good stability, high solubility, and an attractive cell voltage. Two phenyl-linked ferrocene-pyrylium compounds have been synthesized and characterized via mass spectroscopy, nuclear magnetic resonance, and cyclic voltammetry, and have exhibited favorable properties for use in nonaqueous redox flow batteries 

Taylor was with us for what may be a record of 16+ weeks of internship.  We enjoyed having you Taylor.  Keep in touch your last semester at Davenport.

Linked Donor-Acceptor Compounds for use in Symmetric Non-Aqueous Redox Flow Batteries 

Kendra Hagey 

Dr. Thomas Guarr 

Organic Chemistry Storage Laboratory at Michigan State Bioeconomy Institute 

As the need for renewable energy grows, inexpensive and reliable grid storage is necessary to meet the energy demand and stabilize the grid against the intermittency of renewable energy sources like wind and solar. Non-aqueous redox flow batteries offer a higher cell voltage than aqueous flow batteries, as the latter are limited by the narrow potential window of water. However, non-aqueous redox flow batteries face other challenges such as reduced conductivity, higher electrolyte cost, and low solubility. Linking the anolyte and the catholyte together in a symmetric system eliminates the need for a costly ion selective membrane and enables the use of a simple porous membrane to facilitate ion transfer. Various donor-acceptor compounds have been synthesized and characterized using mass spectrometry and cyclic voltammetry. Preliminary tests were conducted to determine electrochemical properties, stability, and solubility. 

This research was supported by Lakeshore Advantage. 

It was a great summer Kendra.  Keep in touch while you continue your studies at UMich.
