Conservation Principles
CHME 2308, Northeastern University

What does it mean to be a chemical engineer? This is the class where we begin to address that. It has to do with relating systems of algebraic equations to situations found in the real world. Once established, this coupling between the world and mathematics allows us to analyze processes, using two important concepts: conservation of mass and conservation of energy. What is a process? Lots of things. Let’s talk about it.

Electrochemical Engineering
CHME 5621, Northeastern University

Electrochemistry is fundamentally an interfacial science, dealing with reactions that happen between an electrode and electrolyte. At this interface, there is a nm-scale separation of charge (the double layer) and a micron-scale concentration gradient (the mass transport boundary layer). Reaction kinetics across the double layer or transport phenomena across the boundary layer may limit cell performance (however that is defined). This class is almost always about figuring out which one. Through the lens of chemical engineering fundamentals, we discuss batteries, fuel cells, electrodeposition, and the process of corrosion. This class is usually taught in the spring semester one day a week from 6:00-9:30 PM. Bring coffee.

Our lab group

Introducing our lab group, seen here at our second ever Friday afternoon group meeting. From left to right, Ben Howell, Matthew Kim, and Zhicheng Lu. All devouring electrochemistry and coming up to speed. The future is truly bright.

I’ve been mulling over what to call the group. “Gallaway Group” would be fine, but as is the fashion these days perhaps it should be something both punchier and more descriptive, with an acronym involved. The Complex Electrochemical Systems Lab (CESL, pronounced “sessil” if you like) is what told Northeastern I might do before I got here, so maybe that’s it. What do I mean by complex? All electrochemistry is complex from a certain point of view. But here I specifically mean systems when multiple phenomena are important throughout the regime of operation, such as two kinds of diffusion (e.g. in a solid crystal and in an electrolyte) or three kinds of kinetics (e.g. both substrate and mediator of an enzyme, also with mediator electrode kinetics). To that you could say “That means all real battery or fuel cell systems are complex.” To which I would say “Yes that’s right.” But this is a defined viewpoint, a worldview, and those are good to set down for all to see. It tells you we will always be trying to break down a complex system, and then build it back up … engineered to be better of course.
