Fabrication, characterization, and measurement of viscosity of α-Fe2O3-glycerol nanofluids

► Fabrication of magnetic nanofluids, ferrofluids, nanoparticles of α-Fe2O3 in glycerol. ► Measurement of the viscosity of the of α-Fe2O3 - glycerol as a function of temperature, shear rate, and volume fraction. ► α-Fe2O3-glycerol nanofluids are non-Newtonian fluids at low volume fraction.
