zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...

Ray Bradbury’s The Martian Chronicles is a futuristic, science fiction novel that chronicles the colonization of Mars by humans, projecting the United States’ colonial and immigrant past on to a symbolic future. Bradbury’s use of language is mostly picturesque and sensory. The present paper applies a text-oriented analysis of stylistic elements that construct meaning in the text and evoke the n...

are needed. Since the analysis depth depends on the accelerating voltage of the electron beam, the application of low accelerating voltages limits the characteristic-X-ray generation region to a minute region near the specimen surface. However, the energies of the X-rays are less than those of the accelerated electrons; this causes a new problem: the use of analytical X-ray lines is limited. Th...
