Self-solidifying active droplets showing memory-induced chirality

Shaping active matter: from crystalline solids to active turbulence

“…We study a two-dimensional (2D) paradigmatic system of isotropic phoretic agents (IPAs) represented by active droplets that have been realized over the last decade [16][17][18][19][20][21][22][23][24][25][26][27][28] and camphor surfers reported in 1862 [29]. An IPA, unlike Janus colloids [30,31], acquires autonomous propulsion through instability, but otherwise in a stable stationary state.…”
