A series of gas-phase reactants is used to treat a Cu-exchanged mordenite zeolite with the aim studying influence reaction environment on formation Cu pairs. The rearrangement ions form multimeric sites as function their oxidation state was probed by X-ray absorption spectroscopy (XAS) and also applying advanced analysis through wavelet transform, method able specifically locate Cu–Cu interacti...

Using N2O4 donor symmetric ligand H2L and dca co-ligand, two new isostructural dinuclear CuII–LnIII complexes [Cu(Cl)(L)Ln(NO3)(CH3OH)(H2O)(dca)] [Ln=Ho (1CuHo), Gd (2CuGd)] [H2L = 6,6′-((1E,1′E)-(ethane-1,2-diylbis(azaneylylidene))bis(methaneylylidene))bis(2-methoxyphenol); dca=dicyanamide] were designed, synthesized studied. In the compounds, geometric environment around nine-coordinated Ln(I...

up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. graphene, a new class of 2d carbonaceous material with atom thi...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...
