Superhydrophobic Nanowire Surfaces for Drop Movement Using Magnetic Fields

Egatz-Gomez A., Melle S., García A.A., Lindsay S., Rubio M.A., Domínguez P., Picraux T., Taraci J., Clement T., Hayes M., Gust D., Arizona State University, US

We present a novel method to control water drop movement on superhydrophobic surfaces through magnetic fields. Water drops with paramagnetic particles can be moved on fractal Si-nanowire superhydrophobic surfaces at high speeds by displacing a [...]

Motion of a Cylinder Partially Filled With a Nano-Ferro-Fluid Suspension in a Magnetic Field

Avula X.J., Washington University in St. Louis, US

This study describes the motion of a partially full cylinder containing a nano-ferrofluid suspension when subjected to magnetic and nonmagnetic forces. The cylinder is allowed to roll from a state of rest without slipping on [...]

Conductance of a Disordered Double Quantum Wire in a Magnetic Field: Boundary roughness scattering

Arapan S.C., Korepov S.V., Liberman M.A., Johansson B., Uppsala University, SE

Boundary roughness scattering in disordered tunnel-coupled double quantum wires in the presence of a magnetic field is considered. The low-temperature conductance as a function of applied magnetic field is calculated for different structure and disorder [...]

Numerical Modeling of Magnetic Field Flow Fractionation in Microchannels: A Two-fold Approach Using Particle Trajectories and Concentration

Berthier J., Pham P., Massé P., LETI, FR

Submicronic paramagnetic particles are currently used for biological applications like medical diagnostic [1]. Recently modeling of displacement of such particles has seen new developments like the calculation of the trajectory of a particle [2], or [...]
