Advances in catalysis rely on the synthesis and characterisation of nanoparticles that have tailored structures and compositions. Although energy-dispersive X-ray (EDX) spectroscopy can be used to study local variations in the compositions of individual supported nanoparticles on the atomic-scale in the scanning transmission electron microscope, electron beam induced damage and contamination ca...

Multiple birefringent rhomboidal crystals seen on histological examination of a resected oesophagus were subsequently found to contain elemental barium and sulphur on energy dispersive x ray ( EDX ) analysis. Scanning electron microscopy and EDX analysis of readily available commercial barium sulphate suspensions suggested that the two forms of barium sulphate previously described in tissue sec...

Thin films of indium doped zinc sulfide (ZnS) for different indium (In) concentrations (x=0.0 - 0.8) were deposited onto glass substrate by spray pyrolysis method at 523K temperature. Aqueous solution of zinc acetate, indium chloride and thiorea were used to deposit the In-Zn-S film. The deposited thin films were characterized by Energy dispersive X-ray (EDX), Scanning electron microscopy (SEM)...

We describe the synthesis of two cyclobutadiene(cyclopentadienyl)cobalt-containing poly(p-phenylene ethynylene)s (PPEs) and their use as precursors for stable ceramic surface coatings. Organometallic PPEs were shaped into hexagonally ordered assemblies by using the breath-figure method. Such breath figures can be washed away with an appropriate solvent. Upon pyrolysis at 500 degrees C under eit...

Since the first demonstration of atomically resolved energy dispersive x-ray spectroscopy (EDX) using a scanning transmission electron microscope (STEM) in 2010 [1], theory based simulations established that EDS hyperspectral maps could be used to measure atomic distances. That is, EDX is an incoherent imaging mode and signal intensity corresponds directly to the structure of the sample [1]. It...

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 ...

Energy dispersive X-ray Fluorescence technique has been used to study five rupee indian coins of years 1992,1993,1994,1999,2009,2010,2011 and 2012 for their material/ elemental compositions. EDX-720 spectrometer provided with X-ray tube and Si(Li) detector having energy resolution 165 eV at 5.9KeV Mn K X-ray. Different metal compositions like Cupro-Nickel, NickelBrass and Ferritic Stainless-Ste...

cuins2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  in  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. the effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  the nanostructures  were  characterized  by  means  of  ...
