Abstract

Nanofluids are suspensions of nano to micrometer sized particles in liquids. A nontypical Dynamic Light Scattering experiment was conducted for measuring the nanoparticles and the aggregates diameter in aqueous suspension. Atomic Force Microscope (AFM) measurements were also carried on and the results are discussed.

Keywords
