Viscosity vs. shear rate (<a onClick="popup('http://www.nanoscalereslett.com/content/6/1/560/mathml/M1','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/6/1/560/mathml/M1">View MathML</a>) dependence of EG/Fe2O3 nanofluids. At 303.15 K and t = 500 s for different weight concentrations: multiplication sign, EG; solid circle, 5 wt.%; solid inverted triangle, 10 wt.%; solid square, 15 wt.%, solid diamond, 20 wt.% and solid triangle, 25 wt.%. The inset shows viscosity vs. time dependence for 25 wt.% nanofluids at controlled shear stress.
