    Physicochemical Properties of Nanofluids Produced from Oxidized Nanoparticles Synthesized in a Liquid by Pulsed Laser Ablation
    (2022) Tahani Flemban; Ridha Hamdi; Hassan Alkhabbaz; Khaled Elsayed; Muidh Alheshibri
    Since pulsed laser ablation in liquid is the most common, simple, and efficient technique to synthesize nanoparticles (NPs). In this work, pure aluminum (Al) and pure copper (Cu) targets are located inside a liquid ambient, next a Nd-YAG Laser of 1064 nm wavelength and 10 Hz pulse repetition is used at four different pulse energies of 30, 50, 70, and 90 mJ to produce Al-NPs and Cu-NPs. After that, a comparative/superlative study, and the physicochemical properties of the prepared nanofluids, (Al-NFs) and (Cu-NFs), have been carried out using transmission electron microscope, scanning electron microscopy with energy-dispersive X-ray spectroscopy, zeta-sizer, UV-Vis spectroscopy, density meter, and viscometer. The influence of laser energy on these properties have been investigated as well.
