comparison. We can make a few preliminary observations. First, the “Future”includes much more material in the systems category than we are suggesting here. For example,“Future” includes general modeling based on material and energy balances and many topics thatwe consider professional skills, e.g., ethics, globalization, intellectual property and so forth.While these topics are important, their link to PSE are tenuous; as a result, the systems topiccould be diluted into an “everything else” category that would not represent its centralimportance. Second, the “Future” proposes coverage of molecular level and multiscale topicsthat require further definition. We will observe the warning that “God (or the devil) is in thedetails”, and therefore, we

To adequately address this problem, the authors’ goal is tosynergize industry-student-academic integration by enculturating classrooms with connections toindustrial realities. Implementation of this model is particularly important in the early years ofthe curriculum. As the first step, the authors are working on designing and incorporating up-to-date industry problems as assignments in a course on “Materials and Energy Balance”. Theauthors have been working with industry mentors from various areas of the chemical engineeringfield to design up-to-date application-based problems/projects for the selected CHE class.

In this problem, thestudents must perform the same type of analysis as the fermentation lab, finding a regressionequation for exponential data. The students were asked to use Excel to find the equation and alsoto plot the data on a piece of log-log paper.
