The prepared MWCNT dispersion was characterized by pH, electrical conductivity tests, measurements of zeta potential
and particle size analysis.
(ii) Zeta Potential
. The surface charge of NV/DNV formulations was assessed by zeta potential
measurements by dynamic light scattering under electrophoresis on a Malvern Zetasizer (Nano-ZS: Malvern, Worcestershire, UK) at 25[degrees]C.

of colloid particles of soymilk protein," Transactions of the Chinese Society of Agricultural Engineering, vol.
Furthermore, the dispersion homogeneity, rheological properties, and mechanical properties were investigated using zeta potential
, reological and mechanical measurements, respectively.
The key parameter for electrokinetic phenomena is the Streaming Potential coupling coefficient and therefore the zeta potential
But if the citrate AuNPs in the zeta cell were replaced by the spare solution that has not been used for measurement before, a good zeta potential
can be observed again, that is, zeta potential
of second measurement of the 3 hours and measurement after 3 hours.
of all milk samples as a function of dilution ratio are shown in Figure 8.
Particle and wall zeta potentials
corresponding to the electrolyte concentrations considered in this study are listed in Table 1 (Gu and Li, 2000; Kang et al., 2004).
The DLS results and zeta potential
measurements both suggest that the compaction efficiency of surfactant increases with the surfactant chain length.
Characterization of Zeta Potentials
. On the base of the pH value, the electrokinetics of the particles was measured as zeta potentials
(1) Zeta potentials
of the fluid samples at the same temperature were measured by Zetasizer (Nano ZS90, MALVERN, United Kingdom).
The negative charge of the dispersed clays from these soils, measured as zeta potentials
, decreased in the order Na>K>Mg>Ca.
