Computational studies have been carried out on 3-hydroxy-3-(2-methyl-1H-indol-3-yl) indolin-2-one (HMI) using both the DFT-B3LYP/6-311+G and HF/6-311+G methods. The optimized geometry of HMI and its bonding parameters as well as IR spectra have been calculated and analyzed. It can be seen that the calculated bond lengths are in good agreement with the(More)
Aimed at high resolution, an asymmetric point spread function has been obtained with good and bad sides by introducing three level asymmetric pupil functions. The good side has decreased side lobes while the bad side has increased side lobes. The asymmetry has been found to increase with the width of the edge strips within the slit aperture. On the other(More)
The nano crystalline Cu doped Ni-Zn ferrites having compositional formula Ni0.2CuxZn0.8-x Fe2O4 (where x=0.0, 0.2, 0.4, 0.6 and 0.8) were synthesized successfully by Citrate-Gel Auto Combustion method at a low temperature (180C). Analysis of the X-Ray diffraction pattern of all the samples confirmed the formation of single phase cubic final structure with(More)
