16 Magnetic Fluids for Thermoelectricity

Fig. 16.5 Normalized initial state Seebeck coefficient as a function of φ with Li + (top) and TBA +
(bottom) counterions measured at three different temperature values. Se ini (0) values indicated in
the inset correspond to the thermogalvanic potential of ferro/ferricyanide redox couple in water.
The inset shows the experimentally determined electrical conductivity of the ferrofluid (with TBA +
counterion) as a function of nanoparticle concentration
16.2.4 Magnetic Nanoparticle Adsorption Phenomena
at the Liquid/metal Interface
While the initial Seebeck coefficient analysis leads to a conclusion coherent with
the existing theoretical model, the time evolution of Se and the steady-state values
exhibited surprising behaviour. First, the apparent steady state is reached only 6–8 h
after the application of temperature gradient. Considering the diffusion coefficient
