stable suspensions obtained by dispersing dry TiO2 nanoparticles
in pure ethylene glycol were prepared and studied. Two types of
nanocrystalline structure were analyzed, namely anatase and
rutile phases, which have been characterized by scanning
electron microscopy. The rheological behavior was determined for
both nanofluids at nanoparticle mass concentrations up to 25%,
including flow curves and frequency-dependent storage and loss
moduli, using a cone-plate rotat
