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...

AbstractBioactive glass with frame of SiO2-CaO-P2O5-ZnO-MgO-SrO was prepared using quick alkali mediated sol-gel process. The functional group analysis, morphology, composition and phase analysis of this glass were done by using FTIR, FESEM, EDX and XRD respectively. The bioactive nature of the sample was analyzed by immersion in Phosphate Buffer Saline (PBS) for a period of 7 days and characte...

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...

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...
