From Electrochemistry in the United States to German Traditions

Madison, Wisconsin - a city that might not immediately come to mind as a must-visit destination in the U.S. However, my three months in Professor Stahl’s lab at the University of Wisconsin-Madison revealed just how much it has to offer. This time was not only an invaluable learning experience in chemistry but also a journey of cultural discovery and personal growth.

 

Diving into Electrochemistry

My research project focused on scaling up an electrochemical batch reaction. This work is particularly significant for the sustainable production of chemical compounds, as electrochemical processes are often more environmentally friendly and energy-efficient than traditional chemical methods. I worked intensively with a Continuous Stirred Tank Reactor (CSTR), which plays a key role in optimizing electrochemical processes. The CSTR ensures uniform mixing of reactants and precise control of reaction parameters such as temperature and pH. For electrochemical reactions, this level of control is crucial to ensure stability and reproducibility.

Interestingly, the CSTR concept can also be applied to everyday processes like cooking. Just as stirring a sauce ensures even mixing, the continuous agitation in a reactor ensures that all components react uniformly. However, while the goal in the kitchen is flavor, in the lab, the focus is on reaction control and efficiency.

Collaborating with Professor Stahl and his dedicated team was highly inspiring. During this time, I significantly enriched my knowledge of electrochemistry and the scaling of such reactions.

Wisconsin's Connection to Germany

Outside the lab, Wisconsin offered countless opportunities for relaxation and exploration. The region is renowned for its culinary specialities - especially cheese and beer. To my surprise, I experienced more Oktoberfest celebrations in Wisconsin than ever before in Germany (outside of Bavaria, of course). It seems the people of Wisconsin have a special appreciation for beer.

Still, there were moments when I missed my German roots, particularly in terms of food. My solution? “Microwave potatoes”! This simple yet satisfying dish brought me a taste of home. It’s a reminder that sometimes the simplest things can provide the greatest comfort.

Conclusion: Balancing Knowledge and Enjoyment

Looking back, my time in Madison was an immense scientific experience. It showed me the importance of trying new things. I encourage anyone who has the chance to pursue such intercultural and professional experiences to take it.
