Synchronized motion of two camphor disks on a water droplet levitated under microgravity

Active chiral dynamics and boundary accumulation phenomenon in confined camphor particles

“…17,18 Moreover, elliptical Janus particles have demonstrated a remarkable phenomenon of giant negative mobility while traversing narrow two-dimensional channels bounded by reflective walls. 17 In particular, with respect to camphor active particles there are investigations related to collective behaviour, 19 synchronization, [20][21][22][23][24][25] and external forcing, 26 among other interesting studies.…”

Sonomaglev: Combining acoustic and diamagnetic levitation

“…Refs. [33][34][35][36][37][38][39][40]; typically a field of order 10 T is required, though levitation of graphite can be achieved using much weaker fields (e.g. Ref.…”
