چکیده

This paper describes our work to magnetically steer self-propelled devices which move by catalysis of hydrogen peroxide. We demonstrate manipulation of paramagnetic particles with a diameter of 100μm to a given setpoint by means of magnetic field gradients, as well as self-propelled movement of gold-platinum rods. We discuss how to reach magnetic torque control of catalytic micro motors.

Confinement-induced enhancement of diffusiophoretic forces on self-propellers

We study the effect of spatial confinement on the strength of propulsive diffusiophoretic forces acting on a particle that generates density gradients by exploiting the chemical free energy of its environment. Using a recently proposed simple model of a self-propelling device driven by chemical reactions taking place on some parts of its surface, we demonstrate that the force significantly incr...

Scanning hall probe microscopy technique for investigation of magnetic properties

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...
