This thesis investigated the interfacial behavior of some selected solutions in contact with one surface of Quartz Crystal Microbalance (QCM). A device was constructed to monitor viscosity of solutions using fundamental frequency of 9 MHz and 10 MHz quartz crystal. Piezoelectric quartz crystals with gold electrodes were mounted by O-ring in between liquid flow cell. Only one side of the crystal was exposed to the solutions which were pumped through silicon tube by a peristaltic pump. The measured frequency shift was observed in order to investigate the interfacial behavior of some selected...

This thesis investigate the role of transition metal (TM) ions in calcium phosphate glass. Various transition metal ions in homogenous calcium phosphate glass were prepared by traditional melt quenching technique. Optical absorption, dielectric spectroscopy, X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy have been used to characterize the structural, optical and electrical features of the glasses. A number of physical studies have also been conducted which include refractive index and density to explore both binary and ternary systems of phosphate glasses. From the...
