Inhibition Mechanisms of Organic Compounds on Copper and Copper Alloys

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Electron interaction with copper(II) carboxylate compounds

In the present study we have performed electron collision experiments with copper carboxylate complexes: [Cu2(t-BuNH2)2(µ-O2CC2F5)4], [Cu2(s-BuNH2)2(µ-O2CC2F5)4], [Cu2(EtNH2)2(µ-O2CC2F5)4], and [Cu2(µ-O2CC2F5)4]. Mass spectrometry was used to identify the fragmentation pattern of the coordination compounds produced in crossed electron - molecular beam experiments and to measure the dependence o...

Formation Constants of the Copper(II) Compounds of Pyridylalpyridylhydrazine

Bivalent copper and the Schiff's base pyridylalpydidylhydrazine form two compounds, composed respectively of one molecule and of two molecules of the organic compound to one atom of copper, and having ultra violet absorption spectra differing only in the value of the molar extinction coefficients at the absorption maxima, 15,100 and 22,450, respectively at 345 mμ. The respective formation const...

Formation of carbon nitride compounds during successive implantations in copper

Copper substrates are successively implanted with carbon and nitrogen (C and N) at high fluences (5×10 and 1×10 at.cm respectively) in order to synthesize specific carbon nitride compounds. The concentration as well as the depth distribution of carbon C and nitrogen N are determined using non resonant nuclear reactions induced by a 1.05 MeV deuteron beam. The use of (d,p) and (d,α) reactions al...
