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

Boehmite nanofluids were synthesized by two step method. In this method Boehmite nano-powder was initially prepared and the powder was dispersed in methanol base fluid by magnetic stirrer method. The prepared nanopowder was characterized by X- ray diffraction (XRD), FTIR and Scanning electron microscopy (SEM). Average particle size has been estimated by using Debye-Scherrer formula. It was found to be about 50 nm. Nanofluids of Boehmite in methanol base fluid were prepared for various molar concentrations and their acoustical studies were made such that different types of interactions could be assessed. Thermo-acoustical parameters of this nanofluids system were computed from ultrasonic velocities, densities and viscosities at temperatures 293K, 298K, 303K, 308K and 313K at fixed frequency 5 MHz over the entire range of concentrations. The obtained results of present investigation have been discussed in the light of interactions between the Boehmite nanoparticles and the molecules of methanol based fluids.Keywords

In this work, ZnO nanoparticles were radially synthesized via sol-gel technique and ZnO nanofluids in distilled water (ZnO-W) and in methanol (ZnO-Me) were produced by two step method. The prepared ZnO nanoparticles are characterised by X-ray diffraction characterized by XRD. Average particle size of synthesized ZnO nanoparticles has been estimated by Debye-Scherrer formula. It was found to be about 30 nm. The particle size distributions of the synthesized nanofluid are measured through acoustic particle sizer (APS-100). The observed features of ZnO nanofluids are discussed in correlation with zetapotential, thermal conductivity and sound velocity. Master ZnO nanofluids with a pH value of about 7 were prepared and stored for different periods under the light and in dark for the evaluation of its antibacterial activities against E coli DH10B by estimating the reduction ratio of the bacteria treated with ZnO.Keywords
