Self - assembly of magnetic
We use Monte Carlo and quaternion molecular dynamics simulations to study the self-assembly of intriguing structures which form in colloidal sus-pensions of small magnetite particles. We show that the only stable isomers with few particles, a ring and a chain, can be eeciently interconverted using a magnetizable tip. We propose to use the oscillating dipole eld of the tip to locally anneal the ...

متن کاملWireless Magnetic-Based Closed-Loop Control of Self-Propelled Microjets
In this study, we demonstrate closed-loop motion control of self-propelled microjets under the influence of external magnetic fields. We control the orientation of the microjets using external magnetic torque, whereas the linear motion towards a reference position is accomplished by the thrust and pulling magnetic forces generated by the ejecting oxygen bubbles and field gradients, respectively...
متن کاملSelf-propelled Leidenfrost droplets.
We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchetlike) topology. The pumping effect is observed when the liquid is in the Leidenfrost regime (the film-boiling regime), for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid ...
متن کاملSelf-regulation in self-propelled nematic fluids.
We consider the hydrodynamic theory of an active fluid of self-propelled particles with nematic aligning interactions. This class of materials has polar symmetry at the microscopic level, but forms macrostates of nematic symmetry. We highlight three key features of the dynamics. First, as in polar active fluids, the control parameter for the order-disorder transition, namely the density, is dyn...
