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

Effects of anodizing conditions on anodic alumina structure
Journal of Materials Science, 2007In this paper, two-step anodization was used to obtain porous anodic alumina (PAA) films, which are widely used as the temples to fabricate nanomaterials. Effects of anodizing conditions such as anodizing voltage and the concentration of electrolyte on steady current density (I s) and anodic alumina structure were investigated for oxalic acid as an ...

Anodic Polarization of Anodized Aluminum
Corrosion, 1969Potentiostatic anodic polarization of anodized coatings on aluminum was sensitive to both coating thickness and degree of seal. The polarization behavior of anodized coatings parallels their performance in atmospheric service. Thus, anodic polarization could be used as a test for the atmospheric corrosion resistance of anodized coatings. The advantages

Publisher Summary This chapter explains Anodic Bonding in detail. In its most used form, the anodic bonding process consists of joining silicon with borosilicate glass. Ceramics can also be used instead of glass. The anodic bonding process, known also as “field assisted sealing,” or “electrostatic bonding” was described for the first time by Wallis ...

Fabricating Anodic Aluminum Oxide by Anodic-Oxidation
Advanced Materials Research, 2011Uniform parallel pores and controllable pore diameter make Anodic Aluminum Oxide (AAO) membrane one of the best materials in synthesis of one-dimensional nano-structured material. High orderly AAO template was prepared by anodic-oxidation. The prepared AAO membrane’s apertures ranged from 30 nm to 75 nm.

Publisher Summary This chapter highlights the anode used in a solid oxide fuel cell (SOFC). Currently, nickel is used exclusively as the SOFC anode material. This metal is preferred primarily because of its low cost. To maintain the required porous structure of nickel over long periods at high temperatures and to provide other desired properties for ...

Mineralogical Characterization of Anode Slimes: Part 8—“Silica” in Copper Anodes and Anode Slimes
Canadian Metallurgical Quarterly, 1991Copper anodes from the CCR, Inco and Kidd Creek refineries contain ≍ 120 ppm SiO2. The silica is present as a variety of complex silicate inclusions preferentially located within 500 pm of the uppe...

Veratric acid treatment by anodic oxidation with BDD anode
Journal of Chemical Technology & Biotechnology, 2011AbstractBACKGROUND: Veratric acid (VA, 3,4‐dimethoxy‐benzoic acid) is representative of the polyphenolic type compounds present in olive mill wastewater (OMW). Given the bactericide factor, the inhibitor character and the anti bacteriological activity of this compound, traditional biological digestion cannot be applied and therefore new technologies ...

Abstract The influence of various pre-anodization voltage (Vs) on pore self-ordering process in anodic alumina (AAO) produced by hard anodization (HA) was investigated. It was demonstrated that the Vs has substantial effect on the pore arrangement in the AAO.
