Diffusion, Microscopy & Imperfections – Week 3

This episode explores three foundational topics in material science: diffusion mechanisms, microscopy techniques, and crystal imperfections. Topics include atomic movement in solids, Fick’s laws, vacancy and interstitial diffusion, as well as grain boundaries, dislocations, and point defects. It also covers the principles behind optical microscopy, SEM, and TEM.The content is structured using AI tools and NotebookLM, based on Materials Science and Engineering: An Introduction (10th Edition) by Callister and Rethwisch. Designed for students seeking clarity on core concepts, this episode breaks down complex material into manageable, exam-ready insights.
