Cu2O hierarchical nanostructures with different morphologies were successfully synthesized by a solvothermal method using copper (II) nitrate trihydrate (Cu(NO3)2⋅3H2O) and ethylene glycol (EG) as initial reagents. The obtained nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) specific surface area test, and UV-vis spe...

Soil microorganisms colonizing soil water sampling devices (lysimeters) reduced concentrations of biodegradable organic chemicals, including 2,4-dichlorophenoxyacetic acid methyl ester, alachlor, methyl m-chlorobenzoate, and metolachlor as water entered through porous ceramic cups. In some cases, losses exceeded 99%. Additions of either a biocide (sodium hypochlorite) or a bacteriostat (copper ...

The effect of various concentrations of divalent cations on survival of gonococci in liquid medium was studied. The growth of Neisseria gonorrhoeae was inhibited by manganous chloride in concentrations above 1 X 10(-5)mol/l while the growth of control organisms such as Neisseria meningitidis and Escherichia coli was not inhibited by the same salt even at 1 X 10(-2)mol/l. Copper sulphate, cobalt...

Copper (Cu) toxicity on plants has become a major problem with increasing agricultural and environmental pollution. The effect of Cu on NADPH-diaphorase (NADPH-d) activity, commonly employed as a marker for nitric oxide synthase (NOS) activity and nitric oxide (NO) production, was investigated in root tips of Vicia faba L. We found that Cu stress stunted root growth and development of root hair...

Abstract Methyl levulinate was selectively formed from glucose and methanol over a copper modified Beta zeolite bifunctional catalyst at 180 °C under argon atmosphere. The selectivity to methyl substantially exceeded previously reported in the open literature results. modification done through an ion-exchange method using solution of nitrate, followed by drying calcination catalyst. Copper chan...

Two novel symmetrical bis!tetradentate Schi} base ligands\ H1L and H3L\ have been prepared from the condensation of N\N?!bis"2!aminopropyl#oxamide with pyridine!1!carbaldehyde and pyrrol!1!car! baldehyde\ respectively[ The ligands react with copper"II# nitrate in basic medium to yield the dinuclear complexes ðCu1LŁ"NO2#1 and ðCu1LŁ[ ðCu1LŁ"NO2#1 reacts with sodium azide to yield the neutral din...

Nanocrystalline complex oxides have been synthesized by combination of sol–gel auto combustion and ultrasonic irradiation techniques using copper nitrate, zinc nitrate as metallic nitrates and glycine, urea and thiourea as fuels. Sol-gel combustion (combination of the chemical sol–gel process and the combustion process) as a proper synthesized technique is used to synthesize ZnO/CuO nanocomposi...

It is a challenge to develop methodologies involving multiple transformations for preparing new materials that cannot be obtained via direct synthesis. Herein, we report an anion exchange process accompanying cation reduction and dimerisation via a single-crystal-to-single-crystal transformation. First, a direct reaction of the flexible tripyridyl dithioether ligand L with CuI afforded a mixtur...
