Novel Synthesis and Ultrasonic Investigation of Al2O3–Xanthan Gum Nanofluid

Abstract

The acoustical qualities of nanofluid molecules are affected by their liquid cohesive properties, which can differ significantly depending on the circumstances. The extracellular polymer xanthan gum is mostly produced by the bacteria Xanthomonas campestris. Its pseudoplastic properties and thermal stability have led to its typical addition to water-based drilling fluids. It is also widely utilized as a thickening and emulsion stabilizer in industrial applications. An innovative method for creating nanofluids is to use ultrasonic technology to convert biopolymer base fluids into nanoparticles. This study uses gelatin as the foundation fluid and various weight percentages to assess the density and ultrasonic velocity of synthesized nanoparticles. The aluminum oxide (Al₂O₃) nanofluids are produced by the study team by ultrasonically transforming a precursor in aqueous xanthan gum. The XRD and FESEM methods are used to characterize the synthesized nanoparticles. After ultrasonication, the findings of ultrasonic velocity, density, and viscosity measurements are analyzed. The stability of nanofluids is investigated using a theoretical framework and experimental data. The outcomes of previous studies and ultrasonic spectroscopy bear striking similarities.
