Microstructural Evolution of Materials: Defects and Diffusion
Discover the principles of point defect evolution that explain materials science phenomena.
Microstructural Evolution of Materials: Defects and Diffusion
Discover the principles of point defect evolution that explain materials science phenomena.
A four-part series of online modules, Microstructural Evolution of Materials introduces various phenomena in various classes of materials. In this course, you will learn how materials develop different microstructures based on the processing technique used, and how these microstructures relate to the properties of the material.
What you'll learn
At the end of this second module of the course, you will be able to:
- Understand the microscopic mechanisms that govern diffusion
- Explain how ion exchange can be used to chemically strengthen glass
- Predict the charge carrier concentration in various charge compensation regimes using the Brouwer approximation.
Prerequisites
- University-level Calculus
- Part 1 of Microstructural Evolution of Materials
- Structure of Materials or other similar course
- Thermodynamics; ideally, 3.012Tx: Thermodynamics of Materials

Principal Lecturer and Digital Learning Scientist
Jessica Sandland is a principal lecturer in MIT’s Department of Materials Science and Engineering (DMSE), where she leads online learning initiatives-- developing massive open online courses (MOOCs), collaborating with faculty, researching best practices in online learning, and designing blended learning experiences for the MIT community. She has overseen the development of a wide variety of DMSE’s online courses, including 3.086x (Innovation and Commercialization), 3.032x (Mechanical Behavior of Materials), 3.024x (Electronic, Optical, and Magnetic Properties of Materials), 3.15x (Electrical, Optical and Magnetic Materials and Devices), and 3.054x (Cellular Solids).
Jessica is one of the co-founders and leads of the MICRO program, whose mission is to provide a remote research and education experience for engineering undergraduates from disadvantaged backgrounds. She also serves as a senior member of Open Learning’s Digital Learning Laboratory. Her current research interests include the utility of peer review in open online courses and the use of humor in MOOCs, and she’s received awards for Best Paper in ‘20 and ‘22 for her contributions to the IEEE LWMOOCs Conference. Jessica also received the 2019 MITx Prize for Teaching and Learning in MOOCs and was a finalist for the 2019 edX prize. Jessica holds a Ph.D. in electronic materials from MIT.
