In the present work, CaFe2O4 nanoparticles have been synthesized using sol-gel method. The prepared nanoparticles have been characterized using X-Ray diffraction (XRD) and transmission electron microscopy (TEM). CaFe2O4 nanoparticles have been dispersed in the ethylene glycol using high power ultrasonicator to prepare CaFe2O4-ethylene glycol based nanofluids of different volume fraction (viz. 0.1 vol%, 0.2 vol%, 0.5 vol%, and 1.0 vol%). Particle size distribution of synthesized nanofluids has been investigated by acoustical particle sizer (APS-100). Frequency and concentration dependent ultrasonic attenuations in the nanofluids have been measured by APS-100. A comparative study of the results, obtained by XRD, TEM and APS, has been done. Various factors responsible for ultrasonic attenuation and their correlation have been made to understand the inter-particle and intra-particle interactions.Keywords

The ultrasonic attenuation and velocities following electron viscosity mechanism has been computed in semi-metallic, superconducting single crystal Iron Selenide(FeSe) in low temperatures 10-70K. We have also calculated the electron-viscosity at different low temperature needed for the calculation of ultrasonic attenuation. The behaviour of ultrasonic attenuation is quite similar to its inverse electrical resistivity. The ultrasonic attenuation due to electron viscosity mechanism is most significant at 15 K. Computed results of ultrasonic parameters have been discussed.Keywords
