Flagellar Dynamics of Chains of Active Janus Particles Fueled by an AC electric field
Daiki Nishiguchi, Junichiro Iwasawa, Hong-Ren Jiang +1
We study the active dynamics of self-propelled asymmetrical colloidal particles (Janus particles) fueled by an AC electric field. Both the speed and the direction of the self-propu…
Zeta potential dependent Self-electrophoresis of Pt-coated Janus particles in hydrogen peroxide solutions
Cheng-Tse Wu, Yen-Wei Lin, Hong-Ren Jiang
We provide experimental results to show that self-propulsion of Janus particles made by coating platinum on the hemisphere of dielectric particles in hydrogen peroxide solution is…
Active Motion of Janus Particle by Self-thermophoresis in Defocused Laser Beam
Hong-Ren Jiang, Natsuhiko Yoshinaga, Masaki Sano
We study self-propulsion of a half-metal coated colloidal particle under laser irradiation. The motion is caused by self-thermophoresis: i.e. absorption of laser at the metal-coate…
Manipulation of Colloids by Nonequilibrium Depletion Force in Temperature Gradient
Hong-Ren Jiang, Hirofumi Wada, Natsuhiko Yoshinaga +1
The non-equilibrium distribution of colloids in a polymer solution under a temperature gradient is studied experimentally. A slight increase of local temperature by a focused laser…
Experimental Test of a New Equality: Measuring Heat Dissipation in an Optically Driven Colloidal System
Shoichi Toyabe, Hong-Ren Jiang, Takenobu Nakamura +2
Measurement of energy dissipation in small nonequilibrium systems is generally a difficult task. Recently, Harada and Sasa [Phys.Rev.Lett. 95, 130602(2005)] derived an equality rel…
