On the mechanisms of dissolution of montroydite [HgO(s)]: Dependence of the dissolution rate on pH, temperature, and stirring rate
(Academic Press Inc Elsevier Science, 2006-05)
The dissolution behavior of montroydite (HgO) has been studied using a fully automated system. Dissolution data under equilibrium conditions are in agreement with previously published data and indicate that HgO solubility ...
Characterization of anodic growth and dissolution of antimony oxide films
(Elsevier Science Sa, 2009-07)
The anodic growth, morphology and stability of antimony oxide films grown in buffered phosphate electrolytes has been characterized by electrochemical methods, in situ ellipsometry and atomic force microscopy. The anodic ...
Characterization of the anodic growth and dissolution of oxide films on valve metals
(Elsevier Science Inc, 2008-03)
Chemical dissolution processes coupled to anodic oxide growth taking place by a "high-field" conduction mechanism, are considered. The equation for the steady-state current density obtained during potentiodynamic polarization ...
Oxidative dissolution of synthetic vivianites as a method for the crystallization of molecular structural motifs
(2021)
Isolation of structural motifs from minerals can be used to improve the understanding of fundamental processes such as catalytic mechanisms and spectroscopic vibrations. In this study, we designed an oxidative dissolution ...
The effect of chloride ions and A. ferrooxidans on the oxidative dissolution of the chalcopyrite evaluated by electrochemical noise analysis (ENA)
(2009-12-28)
It is believed that the dissolution of chalcopyrite (CuFeS2) in acid medium can be accelerated by the addition of Cl- ions, which modify the electrochemical reactions in the leaching system. Electrochemical noise analysis ...
Stability of silver nanoparticles: agglomeration and oxidation in biological relevant conditions
(Springer, 2017-05)
Silver nanoparticles (Ag-NP) are the most used nanomaterial in consumer products due to the intrinsic antimicrobial capacity of silver. However, Ag-NP may be also harmful to algae, aquatic species, mammalian cells, and ...
Oxidative dissolution of bornite by Acidithiobacillus ferrooxidans
(Elsevier B.V., 2010-01-01)
The oxidation of finely ground (-200 mu m) bornite (Cu(5)FeS(4)) by Acidithiobacillus ferrooxidans was evaluated in oxygen uptake and shake flasks experiments. The oxidation was a net acid-consuming reaction. Residual ...
Oxidative dissolution of bornite by Acidithiobacillus ferrooxidans
(Elsevier B.V., 2010-01-01)
The oxidation of finely ground (-200 mu m) bornite (Cu(5)FeS(4)) by Acidithiobacillus ferrooxidans was evaluated in oxygen uptake and shake flasks experiments. The oxidation was a net acid-consuming reaction. Residual ...
Biologically enhanced dissolution of a pyrite-rich black shale concentrate
(1997-01-01)
The acid leaching of a pyrite-rich black shale concentrate (7% S) was tested in this study. The experiments were performed at 5-30% pulp densities and with inoculations of Fe- and S-oxidizing thiobacilli (Thiobacillus ...
Preparation of Chloramphenicol/Amino Acid Combinations Exhibiting Enhanced Dissolution Rates and Reduced Drug-Induced Oxidative Stress
(Springer, 2017-11-20)
Chloramphenicol is an old antibiotic agent that is re-emerging as a valuable alternative for the treatment of multidrug-resistant pathogens. However, it exhibits suboptimal biopharmaceutical properties and toxicity profiles. ...
