Coffee Break with Nanoscience: Film Formation and "Coffee Rings"
Category
Published on
Abstract
This lab explores issues that engineers and scientists face in working with thin film i.e., dealing with two phenomena that work against them: cracking and the coffee ring effect.
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.
