Fig. 4. (a) Mass diffusion coefficient of FF-DMSO with an NP concentration of 3.4% as a function of the magnetic field applied perpendicular (blue) and parallel to the temperature gradient. No redox couple added. The solid lines are fits to eqn (12) as a function of the magnetic field. (b) Soret coefficient as a function of the magnetic field applied perpendicular (blue) and parallel (red) to the temperature gradient in FF-DMSO. The NP volume fraction is 3.4% with 29 mM ClO4−, without a redox couple. The solid lines are fits to eqn (19) as a function of the magnetic field.
