Figure 2From: Electrorheology of nanofiber suspensionsYield stress as a function of electric field strength for Na-titanate nanofiber suspension ( solid circle points ) and titania nanoparticle suspension ( solid square points ). The inset is the corresponding current density of Na-titanate nanofiber suspension (open circle points) and titania nanoparticle suspension (open square point) [72].Back to article page
