This paper is intended to prepare new antimicrobial complexes with proven efficiency. The Schiff base, through the condensation process of salicylaldehyde and p-toludine, its Cu Zn were successfully synthesized. base characterized using molar conductivity, Ultraviolet-visible (UV-Vis), atomic absorption spectroscopy (AAS), Fourier transform infrared (FTIR) techniques. Accordingly, these charact...

The global demand on adipic usage in the production of plasticizers and synthetic polyamide is increasing. In line with search for an efficient energy-conserving way to isolate acid (AA) good yields, this paper introduces oxidization cyclohexanone utilizing two new coordination compounds, [Mn(2,6-pydc)2](imi) (1) [Co(H2pza)2(H2O)2(NO3)].NO3 (2), as catalysts. Compounds 1 2 were synthesized by r...

Scratching beneath the surface: Pt-M(3d)-Pt(111) (M(3d) = Co, Ni) bimetallic subsurface alloys have been designed to show the ligand effect tunes reactivity in oxygen and hydrogen adsorption systems. The platinum-oxygen bond order was investigated by oxygen atom projection in the occupied and unoccupied space using X-ray emission spectroscopy (XES) and X-ray absorption spectroscopy (XAS).

A range of secondary and tertiary phenylacetamides undergo oxidative homodimerization to afford biaryls. The reaction proceeds under palladium catalysis in the presence of a copper cocatalyst and oxygen and is most effective for electron-rich substrates.

Toxic effects due to high aluminum body loads were observed in a number of conditions following ingestion of Al-containing antacids. Bio-availability of aluminum depends not only on the solubility of the ingested salt but also on the physico-chemical properties of the soluble Al complexes formed in body fluids. Amino acids may, upon interaction with Al-salts, form absorbable Al-complexes. Hence...

We present an X-ray absorption near-edge structure (XANES) study of a series of uranium coordination complexes that possess nearly identical first coordination spheres and geometries in a range of oxidation states from U(III) to U(VI). These compounds were obtained through the activation of small molecules, such as ketones, azides, and carbon dioxide, and upon oxidation of a high-valent U(V)≡O ...

A key question in the biological activation of oxygen is how the protein matrix regulates the delivery of oxygen to its site of activation. We are using Escherichia coli copper amine oxidase as a model system to investigate the roles played by both local active site residues as well as long range interactions in this process. We have generated active site mutants, as well as mutants in the puta...
