Density and Shape Effects in the Acoustic Propulsion of Bimetallic Nanorod Motors.
TLDR
The directionality of bimetallic rods in acoustic fields is intriguing and offers some new possibilities for designing motors in which shape, material, and chemical asymmetry might be combined for enhanced functionality. Expand
Twists and Turns of Orbiting and Spinning Metallic Microparticles Powered by Megahertz Ultrasound.
TLDR
An in-depth study of the behaviors of particles activated by ultrasound, especially their in-plane orbiting and spinning dynamics, which could help with developing more powerful and controllable micromachines with biocompatible energy sources. Expand
Autonomous propulsion of nanorods trapped in an acoustic field
Acoustic fields in a liquid medium can trap and suspend small particles at their pressure nodes. Recent measurements demonstrate that nanorods immersed in these fields generate autonomous propulsion,Expand
Autonomous motion of metallic microrods propelled by ultrasound.
TLDR
It is demonstrated that ultrasonic standing waves in the MHz frequency range can levitate, propel, rotate, align, and assemble metallic microrods in water as well as in solutions of high ionic strength. Expand
Hydrodynamics of soft active matter
This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments. This approach offers a unified framework for the mechanical and statisticalExpand
Catalytic nanomotors: autonomous movement of striped nanorods.
TLDR
By solving the convection-diffusion equation in the frame of the moving rod, it was found that the interfacial tension force scales approximately as SR(2)gamma/muDL, where S is the area-normalized oxygen evolution rate, gamma is the liquid-vapor interfacial pressure, R is the rod radius, mu is the viscosity, D is the diffusion coefficient of oxygen, and L is the length of the rod.

Active particles sense micromechanical properties of glasses
TLDR
The translational and rotational dynamics of a self-propelled probe particle with an unconstrained orientational motion can be used to gather information about the mechanical properties of a colloidal glassy system and suggest that active probe particles may be useful for the micromechanical characterization of complex materials.

Wafer-Scale Fabrication of Micro- to Nanoscale Bubble Swimmers and their Fast Autonomous Propulsion by Ultrasound.
TLDR
A method for fabricating bubble swimmers in large numbers with sizes ranging from 5 µm to 500 nm without direct writing or photolithographic tools is described and useful phenomena that enable their propulsion in different modes in the same experiment are revealed. Expand
Reconfiguring active particles by electrostatic imbalance.
TLDR
A general strategy to reconfigure active particles into various collective states by introducing imbalanced interactions is presented, and this strategy of asymmetry-driven active self-organization should generalize rationally to other active 2D and three-dimensional materials. Expand
