In this research work, effect of carbonate content on EPR response of gamma irradiated HAP were investigated. The carbonated HAP samples were prepared by substitution of carbonate group into HAP structure via chemical method. Fourier Transform Infrared (FTIR) spectroscopy and X-ray diffraction (XRD) methods were used to investigate the structural changes of the samples. Then, the samples were s...

A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...
