An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee ...

“Droplets were successfully transported up a 17° incline, achieving accelerations up to 1,628 ± 60 mm/s², purely due to the printed charge patterns – without any external electrodes or ...
