Coffee Break with Nanoscience: Film Formation and "Coffee Rings" (Middle/High School curriculum lesson)

Linked product

This lab will explore the phenomena involved in making thin film coatings. Students will explore the problems that crop up in real- life coating applications, and see how to avoid coffee rings and reduce cracking during the drop-casting deposition of a thin film.
