The present paper reports the synthesis and study of thermo acoustic properties of alpha alumina (α-Al2O3) nano suspension in ethanol base fluid. α-Al2O3 nanoparticles were synthesized through alkoxide route using sol-gel method. Aluminum isopropoxide Al (OC3H7)3, and aluminum nitrate nanohydrate Al (NO3)3 9 H2O were used for preparing alumina solution. Sodium dodecylbenzene sulfonate (SDBS) was used as the surfactant stabilizing agent. The sample was characterized by X- ray diffraction (XRD) and scanning electron microscopy (SEM). Average particle size has been estimated by using Debye-Scherrer formula. The ultrasonic velocity measurement at 4 MHz with an interferometric technique has been made on alpha alumina (α-Al2O3) nano suspension in ethanol base fluid. Measurements were also taken for the density and viscosity. The thermo acoustic parameters were calculated from the velocity, density and the viscosity measurements. By taking measurements over entire range of concentrations and temperatures, we obtained information about the aggregation of nanoparticles in the suspended medium. Thermo acoustic parameters are related to the surface of nanoparticles and nanoparticle surfactant interactions and help for the study of thermo acoustic properties of nanosuspension.Keywords

Boron nitride (BN) is made up of layered structure with equal number of boron and nitrogen. These atoms are held together prominently by Van der Waals forces and their nanostructures have wide range of applicability in biomedical field. BN nanopowder was synthesized by high chemical route method and its characterization has been carried out by X ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR). Ultrasonic characterization of BN has been observed in organic base solvent. Average particle size has been estimated by using Debye-Scherrer formula. It was found to be 70 nm. Thermo acoustic properties of nanomaterials related to the surface of nanoparticles and nanoparticle surfactant interactions. Material characterization of BN nanosuspension was studied by non-destructive technique at various molar concentrations, temperatures and frequencies.Keywords
