Customized Nanofluids

Our Abilities

Preparation of Nanofluids

Alfa Chemistry is able to prepare nanofluids using a one-step method (production of nanoparticles and dispersion of nanoparticles in a base fluid in one step) and a two-step method (first generation of nanoparticles and then dispersion of them in the base fluid).^[1] Our preparation range includes nanofluids with single nanoparticle components, such as alumina nanofluids, aluminum nitride nanofluids, zinc oxide nanofluids, titania nanofluids, silica nanofluids, iron oxide nanofluids, copper nanofluids, carbon nanotubes and nanofluids, gold and silver nanofluids,and multi-component mixed nanofluids such as Cu-Al₂O₃.

Characterization of Nanofluids

In order to characterize the microstructure and morphology, surface chemistry, dispersion size, thermal stability and interaction between the two nanoparticles in the base fluid, we provide characterization techniques including but not limited to: SEM, TEM, XRD, FT- IR, DLS, TGA and zeta potential analysis.

Thermodynamic Performance Analysis

Since the most important application of nanofluids is their heat transfer properties, we can characterize their thermodynamic properties such as thermal conductivity, specific heat, and heat capacity in addition to basic physicochemical characterization of the prepared nanofluids.
