Phase and size of lanthanide-doped nanoparticles are the most important characteristics that dictate optical properties of these nanoparticles and affect their technological applications. Herein, we present a systematic study to examine the effect of alkaline earth doping on the formation of NaYF₄ upconversion nanoparticles. We show that alkaline earth doping has a dual function of tuning parti...

A number of new binuclear complexes have been synthesised by interaction of stable Ni(II) and Cu(II) metal chelates of p-Methylisonitroacetosophenone with Alkaline earth metal salts having general formula[Ma(p-MeINAP)2MbL2 or MbX2]where Ma=Ni(II) or Cu(II),p-MeINAP = deprotonated pMethyiIsonitrosoacetophenone, Mb= Ca ++ or Mg ++ ,L = deprotonated ortho amino benzoic acid and 8hydroxyquinoline X...

The structural stability of AB compounds (A5lanthanide, alkaline earth, transition element; B5dand/or p-block element) has been 5 modelled in terms of atomic properties and represented in the form of structure stability maps. The results on some 520 known binary and ternary known representatives show that the various structure types form rather well-defined stability domains in three-dimensiona...

We report a new method for identifying disulfide linkages in peptides using mass spectrometry. This is accomplished by collisional activation of singly charged cationic alkali and alkaline earth metal complexes, which results in the highly selective elimination of hydrogen disulfide (H2S2). Complexes of peptides possessing disulfide bonds with sodium and alkaline earth metal are generated using...

Doping at the possible A or B site in ABO3 perovskite can alter structural, morphological and optical properties of compounds. Perovskite alkaline earth stannate BaSnO3 doped with Fe resulted BaSn1-xFexO3 compounds having different concentrations (x = 0.00, 0.01, 0.02, 0.03, 0.05 0.07) were prepared by solid-state method. The Rietveld analyzes performed to determine phase purity changes structu...
