Nano-crystalline TiO2 were synthesized by combustion method using metal nitrate solution and urea, glycin and citric acid fuels. Microwave irradiation was used as heating source. X-ray diffraction, scanning electron microscope as well as Fourier transform infrared spectroscopy were performed to characterize the obtained samples. X-ray diffraction patterns revealed that in the case of citric aci...

ZnS nanoparticles (NPs) doped with ‎Ag‎, ‎Cu‎, ‎and AgCu were synthesized using hydrothermal‎ ‎method in water solution‎. ‎The NPS are characterized by X-ray diffraction (XRD)‎, ‎energy-dispersive‎ ‎X-ray spectroscopy scanning (EDX)‎, ‎scanning electron‎ ‎microscopy (SEM) and dynamic light scattering (DLS)‎. ‎The produced NPs have approximately hexagonal structure and a cubic zinc blended struc...

ZrO2 nanopowder was prepared by the sol-gel auto-combustion method. The product was characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). The average crystalline size of ZrO2 was obtained 62 nm. Also, photocatalytic removal of nitrophenol from aqueous solution by using nanoscale ZrO2 under UV ...

In this paper, undopedZnO and Co-ZnOnano structureswith different molar ratio of Cobalt have been synthesized by the sonochemical method. Structure have been characterized by Fourier Transform (FTIR) and UV–Vis spectroscopy,Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (XRD) methods. Moreover, the direct band gap has been calculated by Tauc...

Sphere-like cadmium molybdate (CdMoO4) nanostructures have been synthesized by a large scale and simple sonochemical method by using Cd(Sal)2 (Sal=salicylidene) and Na2MoO4.2H2O for the first time. The effects of sonochemical irradiation time, sonochemical power, temperature, solvent, surfactant and cadmium source were considered to obtain a controlled shape. The as-prepared nanostructured cadm...

the output of x-ray, especially in the field of required energy for diagnosing the disease is very low (in diagnosing lamps, it is less than 1%). in this kind of lamps the rest of the electrical energy is transformed to heat. this considerable amount of heat induces a myriad of too many limitations in choosing higher levels of radiation, particularly in specialized techniques. this process is t...

Papayas, rambutans, and Kau oranges were irradiated at 0 (control) and 0.75 (irradiated) kGy and stored for 2 and 9 days to determine the Hect of X-irradiation on objective and sensory quality attributes. Irradiation at 0.25 kGy, as a minimum dose, has been approved as a quarantine treatment for the export of tropicalmts grown in Hawaii. The fleets of irradiation and storage on specific sensory...

The sulfhydryl enzyme malate synthase was shown to undergo an X-ray induced aggregation and inactivation in solution (Zipper and Durchschlag, Radiat. Environ. Biophys. 18, 99-121 (1980). Further evidence for the occurrence of aggregation and inactivation and also of fragmentation and partial unfolding of the enzyme upon X-irradiation was obtained by chemical and electrophoretic studies. Irradia...
