Anodic Oxidation of Pentaphenylcyclopentadienes [PDF]
, 1986 Cyclic voltammetric oxidation of 1,2,3,4,5-pentaphenylcyclopentadiene has been studied in non-polar chloroalkane solvents (CH2Cl2 and CH2ClCH2Cl). The oxidation is reversible if tetra-n-butylammonium hexafluorophosphate (TBA^+PF6^-) is used as supporting electrolyte, but irreversible when tetra-n-butylammonium perchlorate (TBA^+ClO4^-) or tetra-n ...

The anodic oxidation of neodymium
Electrochimica Acta, 1979The anodic oxidation of neodymium was investigated by the galvanostatic technique in Na2-HPO4 - ethylene glycol solution. According to the combination of measurments of ac capacity and of specular reflectivity, we obtained a refractive index for the oxide films as a function of wavelength and the value of apparent dielectric constant of the films for ...

Anodic oxidation of benzoquinone using diamond anode
Environmental Science and Pollution Research, 2014The anodic degradation of 1,4-benzoquinone (BQ), one of the most toxic xenobiotic, was investigated by electrochemical oxidation at boron-doped diamond anode. The electrolyses have been performed in a single-compartment flow cell in galvanostatic conditions. The influence of applied current (0.5-2 A), BQ concentration (1-2 g dm(-3)), temperature (20-45

The anodic oxidation of uranium
Acta Metallurgica, 1954Abstract Over a range of 2–100 volts the anodic oxidation of uranium in ammoniacal ethylene glycol produces oxide films which are predominantly uranium dioxide in composition. The oxide formed in this manner shows considerable stability to atmospheric corrosion.

Anodic oxidation of triphenylphosphinephenylimine
Electrochimica Acta, 1977Abstract Anodic oxidation of triphenylphosphinephenylimine in acetonitrile has been examined by voltammetry, controlled potential coulometry, and electron spin resonance spectroscopy. Product analyses showed that triphenylphosphine oxide and mixtures of polymeric oxidized salts of aniline are major products along with unreacted starting material.

Philosophical Magazine B, 1987
Abstract Key aspects of anodic film growth on aluminium at ambient temperatures in aqueous electrolytes, encompassing barrier- and porous-type films, are described. By direct observation of film sections, incorporating inert marker layers and tracers, in the transmission electron microscope and appropriate analysis, the locations of solid-film growth ...

Anodization current efficiency measurements were used to determine the oxygen content of sputtered tantalum films. Films consisting mainly of b.c.c. Ta had less than 5 at.% oxygen while 'normal' β-Ta contained 10–15 at.% oxygen. Films with a more negative temperature coefficient of resistance had a higher oxygen content.The field strength required to ...

On the Anodic Oxidation of Columbium
Journal of The Electrochemical Society, 1960The anodic oxidation behavior of niobium was studied by determining the volthge-current characteristics of niobinm at 300 volts in a 0.1% H/sub 3/PO/sub 4/ solution from 1 to 80 tained C. The - current rapidly decays to the leakage current level and thereafter remains constant up to a certain time, after which it increases abruptly and goes out of ...

The anodic oxidation of InAlAs is investigated by transmission electron microscopy, Rutherford backscattering spectroscopy and medium energy ion scattering in order to elucidate the mechanism of oxide growth. For this purpose, anodizing was carried out at 5 mA cm−2 in 0.1 M sodium tungstate and 0.1 M ammonium pentaborate electrolytes at 293 K, which ...
