“…The circulation of cathodic current induces a pH shift towards alkaline values which promotes the growth of calcareous deposits [5,15,22] and enhances the repair of the reduced oxide film on the surface [41][42][43].…”

“…As polarization went on, both R ox and R ct increased continuously. It can be inferred that passive film will not be reduced under polarization at −0.50 V [9,15]. With the polarization at −0.50 V, the dominant cathodic reaction on the surface of 304 SS is the oxygen reduction.…”

“…The passive behavior of stainless steel is affected by many factors, such as types of stainless steel, pre-treatment, electrolytes, and applied potentials [13][14][15][16]. The reduction of passive film on stainless steel with cathodic polarization at a certain potential will also lead to high risk of corrosion [17].…”

Abstract:The change of protective current density, the formation and growth of calcareous deposits, and the evolution of passive film on 304 stainless steel (SS) were investigated at different potentials of cathodic polarization in sea water. Potentiostatic polarization, electrochemical impedance spectroscopy (EIS), and surface analysis techniques of scanning electron microscopy (SEM), energy dispersive X-ray (EDX) microanalysis and X-ray diffraction (XRD) were used to characterize the surface conditions. It was found that the protective current density was smaller for keeping polarization at −0.80 V (vs. saturated calomel electrode (SCE), same as below) than that at −0.65 V. The calcareous deposits could not be formed on 304 SS with polarization at −0.50 V while it was well protected. The formation rate, the morphology, and the constituent of the calcareous deposits depended on the applied potential. The resistance of passive film on 304 SS decreased at the first stage and then increased when polarized at −0.80 V and −0.65 V, which was related to the reduction and the repair of passive film. For the stainless steel polarized at −0.50 V, the film resistance increased with polarization time, indicating that the growth of oxide film was promoted.

“…H 2 O 2 is also formed on submerged surfaces by organisms in the biofilm (Chandrasekaran and Dexter 1993;Le Bozec et al 2001;Dexter et al 2003). Local concentrations of H 2 O 2 in the biofilm can approach 50 mM.…”

“…If these catalysts were covalently sequestered within a porous film coating, the catalysts should react with the peroxide found in seawater (Cooper and Zika 1983;Willey et al 1999;Schiller 2000, 2001;Clark et al 2008) or that is produced by the biofilm (Chandrasekaran and Dexter 1993;Le Bozec et al 2001;Dexter et al 2003) and with the halide salts found in seawater to create a surface that is chemically inhospitable to settlement and adhesion. Specifically, the catalysts would generate hypohalous acid or 'bleach' on the coating surface.…”

Halide-permeable xerogel films prepared from sols containing 50 mol% aminopropyltriethoxysilane (APTES)/50 mol% tetraethoxysilane (TEOS) or 10 mol% APTES/90 mol% TEOS and 0.015 M selenoxide or telluride catalyst in the sol gave reduced settlement of cypris larvae of the barnacle Balanus amphitrite and larvae of the tubeworm Hydroides elegans in the presence of artificial seawater (ASW) and hydrogen peroxide (5-100 mM) relative to glass controls. Settlement of Ulva zoospores was lower on both the 50 mol% APTES/50 mol% TEOS and 10 mol% APTES/90 mol% TEOS xerogel formulations in comparison with glass controls with or without the added catalyst. The 50 mol% APTES/50 mol%TEOS xerogel containing telluride catalyst gave reduced settlement of Ulva zoospores in the presence of 100 mM H 2 O 2 in ASW compared with the same coating without added peroxide. Scanning electron microscopy and XPS data suggest that exposure to H 2 O 2 does not lead to chemical or morphological changes on the xerogel surface.

Biological and biochemical studies of inorganic and organic complexes of tellurium are reviewed. Subject areas include the biosequestration and bioincorporation of tellurite and other inorganic tellurium compounds as well as tellurite‐resistant bacteria. The incorporation of tellurium into amino acids (tellurocysteine) and the formation of unnatural glutathione peroxidases and thioredoxin reductases incorporating tellurocysteine are also described. Low molecular weight organotellurium compounds that mimic glutathione peroxidase and the thioredoxin reductases are discussed as are inorganic and organic tellurium compounds that inhibit cysteine proteases and related enzymes. The interactions of P‐glycoprotein with organotellurium compounds to give stimulators and inhibitors of ATPase activity in the enzyme are described. The role of tellurium‐containing chromophores in the photodynamic therapy of cancer and the photodynamic inactivation of viral and bacterial pathogens is also reviewed. The binding modes of tellurium‐containing chromophores to DNA are also described.
