This course combines three parts. First, it will cover fundamental aspects of kinetics, mass-transport, and fluid physics that are relevant to microfluidic systems. Second, it will provide an understanding of how new technologies are invented and reduced to practice. Finally, students in the course will work together to design microfluidic systems that address challenges in Global Health, with an emphasis on students' inventive contributions and creativity. Students will be encouraged and helped, but not required, to develop their inventions further by working with OTT and entrepreneurial resources on campus. Participants in this course benefit from enrollment of students with diverse backgrounds and interests. For chemical engineers, suggested but not required courses are ChE 101 (Chemical Reaction Engineering) and ChE 103 abc (Transport Phenomena). Students are encouraged to contact the instructor to discuss enrollment.

Hands-on experience will be provided via separate laboratory sessions using solid NMR spectrometers at Caltech Solid State NMR facility.

Student groups complete high-level design of a chemical process or product, while learning about and using the engineering design cycle, methods of creativity, technology evaluation, and entrepreneurship. Each team generates, filters, and refines project concepts; identifies stakeholders, needs, and requirements; ideates and evaluates technologies, selecting suitable options based on readiness, benefits, and strategy; develops a project budget and schedule for a proof of concept; and writes a proposal. Each project must meet requirements for societal impact, budget, duration, person hours, environmental impact, safety, and ethics.

After selecting a project from a collection of proposals, student groups design, build, and test a proof of concept for the proposed chemical process or product, subject to schedule, financial, and other constraints. Students are encouraged and helped, but not required, to collaborate with on-campus subject-matter experts, laboratories/centers, and OTT/entrepreneurial resources.

In this capstone course, students design, build, and test a proof of concept for a chemical process or product, subject to constraints related to finances, schedule, environmental impact, safety, and ethics. Students learn about and use methods of creativity, the engineering design cycle, and rapid prototyping.

Each student is required to design, construct, and troubleshoot their own process, then use chemical engineering principles to experimentally evaluate and optimize process metrics or material attributes. Where possible, cost analysis is performed.

The project may be an original research idea; related to work by a research group at the Institute; an entry in a relevant national/regional contest; a response to an industry relationship; or other meaningful opportunity. There is no lecture, but students participate in weekly progress updates. A student may not select a project too similar to research completed to fulfill requirements for ChE 80 or ChE 90 abc.
