Separation of bi-dispersed microspheres in dusty plasma ratchet experiments
Ting-yu Yao, Ji-xu Gao, Miao Tian +4
It is demonstrated experimentally that the effective separation of bi-dispersed microspheres (dust particles) in the underdamped and strongly-coupled regime is realized using a des…

Separating micrometer-sized particles utilizing a dusty plasma ratchet
Zhi-min Cai, Zong-bo Ma, You-kai Zhao +2
Directional transport-dominated particle separation presents major challenges in many technological applications. The Feynman ratchet can convert the random perturbation into direc…

Experimental demonstration of a dusty plasma ratchet rectification and its reversal
Ya-feng He, Bao-quan Ai, Chao-xing Dai +5
The naturally persistent flow of hundreds of dust particles is experimentally achieved in a dusty plasma system with the asymmetric sawteeth of gears on the electrode. It is also d…
