High quality x-ray mapping (XRM) has been used for over 30 years by experienced wavelength dispersive spectroscopy (WDS) operators. Manufacturers have been developing similar techniques using energy dispersive spectroscopy (EDS) over the last 20 years. This has been generally unsuccessful due to a number of problems such as poor computer specifications, cost, time to map and generally poor peak...

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 ...

This paper is concerned with a class of nonlocal dispersive models – the θ-equation proposed by H. Liu [ On discreteness of the Hopf equation, Acta Math. Appl. Sin. Engl. Ser. 24(3)(2008)423–440]: (1− ∂ x)ut + (1− θ∂ x) ( u2 2 ) x = (1− 4θ) ( ux 2 )
