Abstract Alternative to the traditional analog methods, several digital data preprocessing, shaping and postprocessing techniques have been investigated for improvement in energy resolution of dispersive x-rays detectors. Initial experimental results show that by preprocessing data, better can be obtained at shorter times; thus, it will allow good time high count rates.

nowadays various methods are presented for synthesis of barium strontium titanate (bst) nanopowders with different morphology and properties. each of these (bst)s has got individual characterization that makes it suitable for a special application. every method has a special quality, causes it to have preference over the other methods. low processing temperature is a desired point which most of...

polyvinylpyrrolidone  /  nickel  oxide  (pvp/nio)  dielectrics  were fabricated  with  sol-gel  method  using  0.2  g  of  pvp  at  different working  temperatures  of  80,  150  and  200  ºc.  structural  properties and surface morphology of the hybrid films were investigated by x-ray  diffraction  (xrd)  and  scanning  electron microscope  (sem) respectively. energy dispersive x-ray spectrosc...

An electron microscopic technique, energy-dispersive x-ray (EDX) analysis, was applied to rat tissue specimens containing gadolinium diethylenetriamine-pentaacetic acid (DTPA). EDX spectroscopy was able to detect the characteristic radiation spectra of gadolinium from tissues in concentrations as low as 0.005 mmol per gram of tissue. A mapping algorithm allowed the detected spectra to be assign...
