The history of the elemental technologies (underlying technologies) used in a particular research field is essential for analyzing technical trend in the field. However, it is too costly and time-consuming to collect and read all of the papers in the field for the purpose of this analysis. Therefore, we have constructed a system that can recognize the application of elemental technologies to an...

This study was carried out with the aim of developing the methodology to determine elemental composition in wheat and identify the best germplasm for further research. Orphan and genetically diverse Afghan wheat landraces were chosen and EDXRF was used to measure the content of some of the elements to establish elemental composition in grains of 266 landraces using 10 reference lines. Four elem...

Control of elemental impurities in pharmaceutical materials is currently undergoing a transition from control based on concentrations in components of drug products to control based on permitted daily exposures in drug products. Within the pharmaceutical community, there is uncertainty regarding the impact of these changes on manufactures of drug products. This uncertainty is fueled in part by ...

In this paper, we report the synthesis and characterization of a new symmetric macroacyclic Schiff base ligand (H2L) and related complexes with different metals. (H2L) was synthesized by the one pot condensation reaction of 2-[2-(2-formyl phenoxy)ethoxy]benzaldehyde and 2-aminobenzenethiol in a 1:2 molar ratio. The acyclic Schiff base was characterized by IR, NMR spectroscopy and elemental anal...
