As the demand for higher education continues to grow and as governments acknowledge their role in promoting economic development, it becomes increasingly important to ensure that higher education systems are managed in an effective way. Higher education systems are also getting more complex due to the growth in the number of public and private institutions, so that the task of managing and monitoring the sector is becoming more specialized and demanding. Everyone agrees that the expansion of the higher education to cope up with the escalating demand is possible only if substantial participation of the private sector is encouraged. -
Effect of Calcium Stoichiometry on the Dielectric Response of Cacu3ti4o12 Ceramics P.Thomas, K.Dwarakanath, K.B.R.Varma
Effect of calcium stoichiometry on the dielectric response of CaCu3Ti4O12 Ceramics P.Thomas,a,b K.Dwarakanath,a K.B.R.Varma b a Dielectric Materials Division, Central Power Research Institute, Bangalore : 560 080, India. b Materials Research Centre, Indian Institute of Science, Bangalore: 560012,India. Abstract CaxCu3Ti4O12 (x = 0.90, 0.97, 1.0, 1.1 and 1.15) polycrystalline powders with variation in calcium content were prepared via the oxalate precursor route. The structural, morphological and dielectric properties of the ceramics fabricated using these powders were studied using X-ray diffraction, Scanning Electron Microscope along with Energy Dispersive X-ray Analysis, Transmission Electron Microscopy, Electron Spin Resonance (ESR) spectroscopy and Impedance analyzer. The X-ray diffraction patterns obtained for the x= 0.97, 1.0 and 1.1 powdered ceramics could be indexed to a body–centered cubic perovskite related structure associated with the space group Im3. The ESR studies confirmed the absence of oxygen vacancies in the ceramics that were prepared using the oxalate precursor route. The dielectric properties of these suggest that the calcium deficient sample (x= 0.97) has a reduced dielectric loss while retaining the high dielectric constant which is of significant industrial relevance. Keywords: Sintering; Grain boundary; Dielectric properties; CaCu3Ti4O12. 1. Introduction High-permittivity dielectric materials have attracted ever-increasing attention particularly for their practical applications in microelectronics such as capacitors and memory Corresponding author : Tel. +91-80-2293-2914; Fax: +91-80-2360-0683. E-mail : [email protected] (K.B.R.Varma) devices. The CaCu3Ti4O12 (CCTO) ceramic belongs to a family of the type, ACu3Ti4O12 (where A= Ca or Cd) and has been reported in the year 1967 [1]. -

The lack of affordable and real-time sensors available to monitor these contaminants limits effective conservation and management strategies. To support the development of sensing technology to identify certain contaminant ions and measure their concentrations, a systematic study of the dielectric spectra of environmentally-relevant electrolyte liquids has been conducted for frequencies up to 20 GHz. Aqueous solutions of nitrate, sulphate, and chloride anions (all based on the sodium cation) were prepared with concentrations up to 400 mg/L (approximately 10 to 20 mmol/L). A temperature bath was employed, to hold the samples at temperatures 10, 15, 20, 25, and 30 degrees Celsius while the dielectric spectrum was measured. Conductivity was also measured independently, to reduce uncertainty in obtaining other parameters by spectral fitting. The measured spectra were fitted with a Debye model using a non-linear, weighted, least-squares analysis. The data were fitted by a concentration-dependent parametric model that includes terms accounting for internal ionic fields and the solvent dilution effect (mixture relation), the kinetic depolarization effect, the dielectric saturation effect, and the Debye-Falkenhagen effect that accounts for the contribution of ionic atmosphere polarization. The relative contributions of these effects will be discussed and conclusions drawn in regards to the best indicators that might be extracted from the measured data and judiciously employed to establish a basis for developing a low-cost sensing system that distinguishes between these ions and determines their concentration. -
