introduction: due to the cell labeling potentials of various metal-maltol complexes, the idea of developing a possible cell labeling imaging agent using single photon emission computed chromatography (spect) with[111in]-maltolate complex has been investigated. methods: [111in] labeled 3-hydroxy-2-methyl-4h-pyran-4-onate ([111in]-maltolate) was prepared using freshly prepared [111in]incl3 and ...

Ni6(N2H4)6(SO4)4(OH)2(H2O)8](SO4)(H2O)10 complex was prepared according to literature report. The reaction between aforementioned complex via sodium alkoxides as a reactants, were carried out in the solid state. The [Ni6(N2H4)6(SO4)4(OH)2(H2O)8](SO4)(H2O)10 undergoes an intramolecular two electrons oxidation-reduction reaction at room temperature and metallic nickel nanoparticles (Ni1-Ni5) was ...

The complexation of Alkali metal cations by the water-soluble p-sulfonic acid calix(4)arenewas thermodynamically characterized using spectrophotometeric data which are consistentwith the formation of a 1:1 complex resulting from electrostatic interactions between thesulfonato groups and alkali metal cations. In this study, we determined the formationconstants (log K) of the complexes and have c...

First, Schiff base iminopyridine ligands has been prepared by the condensation between primaryamines, different substituted anilines and active carbonyl group of pyridine carboxaldehyde, thenthe complexes [diiodo (3-ethylphenyl) pyridine-2-yl methylene amine] mercury(II), complex a,[dibromo (2,5-dimethylphenyl) pyridine-2-yl methylene amine] mercury(II) complex b, and[dinitrato bis-(2,6-dimethy...

introduction: water shortage in arid and semiarid regions of the world is a cause of serious concerns. the severe water scarcity urges the reuse of treated wastewater effluent and marginal water as a resource for irrigation. mobarake steel complex has been using treated industrial wastewater for drip-irrigation of trees in about 1350 ha of its green space. however, wastewater may contain some a...
