‎The problem of two-phase MHD boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. The effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. The governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

In this paper we have studied a new form of Non-Commutative (NC) phase space with an oper-atorial form of noncommutativity. A point particle in this space feels the effect of an interaction with an " internal " magnetic field, that is singular at a specific position θ −1. By " internal " we mean that the effective magnetic fields depends essentially on the particle properties and modifies the s...

This article presents a method to investigate how magnetic particle characteristics affect their motion inside tissues under the influence of an applied magnetic field. Particles are placed on top of freshly excised tissue samples, a calibrated magnetic field is applied by a magnet underneath each tissue sample, and we image and quantify particle penetration depth by quantitative metrics to ass...

A generating function, expressed as a power series in the particle Larmor radius, is used to relate an arbitrary set of magnetic field line coordinates to particle canonical variables. A systematic procedure is described for successively choosing the generating function at each order in the Larmor radius so that the transformed particle Hamiltonian is independent of the Larmor phase angle. The ...

The motion of an active (self-propelling) particle with a permanent magnetic moment under the action of a rotating magnetic field is considered. We show that below a critical frequency of the external field the trajectory of a particle is a circle. For frequencies slightly above the critical point the particle moves on an approximately circular trajectory and from time to time jumps to another ...

Magnetic traps are an important instrument for analyzing the behavior of systems and biological processes. They manipulate magnetic particles by applying a force under the influence of magnetic fields. Controlling the position of the magnetic particle for single molecule studies is difficult due to the complexity of the instrument because its dynamics can change per experiment. This results in ...

We present the results of Monte Carlo simulations of a model of a γ-Fe 2 O 3 (maghemite) single particle of spherical shape. The magnetic Fe 3+ ions are represented by Ising spins on a spinel lattice that consists on two sublattices with octhaedral and tetrahedral coordination with exchange interactions among them and with an external magnetic field. By varying the particle diameter, we have st...

In this research, some more applicable ferrofluids are produced and their mechanical specifications are measured, experimentally. Also, their treatments in the ventilated cavity geometry are assessed numerically. The magnetite nanoparticles are produced by a chemical combination of Fe2+ and Fe3+ with NH3. In order to solve the nanoparticles in the new mediums, a...
