چکیده
The specific absorption rate (SAR) of a dilute assembly spherical iron nanoparticles with cubic anisotropy distributed in viscous liquid is calculated using the solution stochastic Landau - Lifshitz equation for unit magnetization vector and equations multiple particle directors that specify spatial orientation nanoparticle liquid. magnetic reversal modes particles are revealed at low sufficiently high amplitudes alternating field, respectively. SAR shown to exceed significantly oxide uniaxial same frequencies applied field. linear response theory be valid only small field amplitudes, H0 < 50 70 Oe.

Laser-induced thermophoresis of individual particles in a viscous liquid.
This paper presents a detailed investigation of the motion of individual micro-particles in a moderately-viscous liquid in direct response to a local, laser-induced temperature gradient. By measuring particle trajectories in 3D, and comparing them to a simulated temperature profile, it is confirmed that the thermally-induced particle motion is the direct result of thermophoresis. The elevated v...

We show that a minimal model for viscous fingering with a nematic liquid crystal in which anisotropy is considered to enter through two different viscosities in two perpendicular directions can be mapped to a twofold anisotropy in the surface tension. We numerically integrate the dynamics of the resulting problem with the phase-field approach to find and characterize a transition between tip sp...
متن کاملDynamics of particle - particle collisions in a viscous liquid
When two solid spheres collide in a liquid, the dynamic collision process is slowed by viscous dissipation and the increased pressure in the interparticle gap as compared with dry collisions. This paper investigates liquid-immersed head-on and oblique collisions, which complements previously investigated particle-on-wall immersed collisions. By defining the normal from the line of centers at co...
متن کاملTen themes of viscous liquid dynamics
The solidity of viscous liquids – their “solid-like-ness” – gives rise to several conjectures, here referred to as themes. We show how these themes point to a general description of equilibrium viscous liquid dynamics at a given temperature. This description is based on standard time-dependent GinzburgLandau equations for the density fields, stress tensor fields, potential energy density field,...
