  Abstract
  The Co-Ni ferrites with general formula Co1-xNix Fe2O4 (where x=0.0, 0.05, 0.10, 0.15, 0.20) were prepared by solid state root method. X-ray, K- absorption fine structural measurements were carried out. EXAFS spectra have been recorded at the K-edge of Fe using the dispersive EXAFS (DEXAFS) beam line at 2.5GeV Indus-2 synchrotron radiation source RRCAT, Indore, India. The EXAFS data have been analysed using the computer software Athena. These have been used to determine the bond lengths in these ferrites with the help of four different methods, namely, Levy’s, Lytle’s and Lytle, Sayers and Stern’s (LSS) methods.

  Abstract
  The ultrasonic velocity (u), density (ρ) and viscosity (ƞ) have been measured at 2 MHz frequency in the binary mixtures of β-alanine with water over entire range concentration at 323 K using ultrasonic Pulser Receiver technique. The experimental data have been used to calculate acoustical parameter namely adiabatic compressibility (βa), acoustic impedance (z), free length (Lf) with a view to investigate the nature and strength of molecular interaction in the binary liquid mixture. The obtained result support the occurrence of complex formation through intermolecular hydrogen bonding in there binary liquid mixtures.
