Preparation and characterization of spray-pyrolysed BaTiO3 films
Tripathi, A K; Chariar, Vijayaraghavan; Goel, T C; Pillai, P K C (1994)Thin films of BaTiO3 were prepared by spray pyrolysis of BaTiO3 sol. The structural and dielectric characteristics of these films are reported in this study. The results indicate that spray pyrolysis could be an useful ... -
Spatial amplification via photorefractive two-beam coupling; real-time image processing using controllable erasure of Fourier spectrum
Joseph, Joby; Singh, K; Pillai, P K C (1991)A real-time image processing technique has been described, using a two-beam coupling geometry in photorefractive materials. An erase beam copropagating with the signal beam allows spatial amplification of selected frequency ... -
Spectrophotometric studies of chemical species using tapered core multimode optical fiber
Vishnoi, Gargi; Goel, T C; Pillai, P K C (1997)A spectrophotometer has been developed using tapered core multimode optical fiber (PCS-600). It is based on the phenomenon of evanescent wave absorption and is capable of identifying the chemical species having the absorption ... -
Thermally stimulated discharge current studies in a polymethyl methacrylate polystyrene blend
Verma, A; Tripathi, A K; Chariar, V; Goel, T C; Pillai, P K C (1994)Thermoelectrets were prepared using polymethyl methacrylate (PMMA), polystyrene (PS) and their blend in the 50:50 weight ratio. The TSDC spectra of PMMA shows both dipolar and space charge peaks, while the TSDC spectra of ...
