a simple hydrothermal method was designed for the synthesis of the nanostructure barium phosphonate in presence of cetyltrimethylammonium bromide (ctab) or sodium dodecyl sulfate (sds) as surfactant. ft-ir, edax, xrf, xrd, sem were used to characterize this material. effect of solvent on morphology complex was discussed. thermogr avimetric analysis (tga) shows the existence of porosity and stab...

Incorporation of [Fe(bipy)Cl4][bipy.H] (1) (where bipy is 2,2′-bipyridine) in the molecular sieves of the type LTA, NaY and mesoporous Al-MCM-41 by using a “ship in a bottle synthesis” approach was investigated. [Fe(bipy)Cl4][bipy.H] was successfullyincorporated in the channels ofmesoporousAl-MCM-41, and the product was characterized by X-ray diffraction, FTIR and BET analysis. It was fou...

Network reliability evaluation is important for the planning, design and control of arbitrary systems. A novel set theory based method for deriving terminal reliability expressions of complex system configurations is described in this paper. The reliability formula of a networked system is expressed as sum of disjoint products, where the product terms represent conjunctions of Boolean variables...

Assuming that categorical differentiation is major acoustic characteristics of English lexical stress through binary instead of more complex 3-way distinction, we investigated lexical stress in broad and narrow focus positions and found how binary distinction is achieved by the concomitancy of secondary stress defined by its position and distance in relation to primary stress. Similar results a...

in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligan...

imaging of infection and inflammation is an important issue in nuclear medicine as it may have relevant implication for the management of patients with infections or inflammatory diseases. in this regard the synthesis of human polyclonal immunoglobuline g (igg) radiolabeled with technetium-99m (99mtc) by a novel method, via a nicotinamide hydrazine derivative, was performed. the biological beha...
