What this dataset shows

Fluorescence microscopy videos of particle deposition from evaporating colloidal drops, comparing ellipsoidal and spherical particles (v1 and v2) [1], and interferometry videos of evaporating colloidal drops containing particles with varying wettability (v3 and v4) [2].

Fluorescence microscopy of ellipsoidal particles (aspect ratio 6.5) in an evaporating water drop, seen from below; they deposit uniformly instead of forming a coffee ring (README video v1). The 10 µm scale bar is from the original recording. View original source

Ellipsoids deposit uniformly (v1) while spheres form a coffee ring (v2). In the interferometry videos the contact line moves in stick-slip steps at 74° (v3) and recedes smoothly at 34° (v4). Video numbers follow the dataset README.
