Toward efficient electrocatalytic degradation of iohexol using active anodes: A laser-made versus commercial anodes
(2022-07-01)
The X-ray iodinated contrast medium iohexol is frequently detected in aquatic environments due to its high persistence and the inefficiency of its degradation by conventional wastewater treatments. Hence, the challenge ...
Structural changes in TiO2 films formed by anodizing of electro-polished titanium
(2016-01-01)
Anodizing is a surface modification technique that is applied to growing oxide films on Ti to accelerate the osseointegration of an implant. Besides the surface roughness, the crystalline structure of these films can affect ...
Evaluation of surface pretreatment stages of Al 1050 to obtain nanostructured anodic films
(Academic Press Ltd - Elsevier Science Ltd, 2019-04)
The growth and ordering of the anodic aluminum oxide layer depend strongly on the initial roughness of the substrate and consequently on the different pretreatment stages. The objective of this study was to select the best ...
Tribocorrosion behaviour of anodic treated titanium surfaces intended for dental implants
(2013-10-09)
Tribocorrosion plays an important role in the lifetime of metallic implants. Once implanted, biomaterials are subjected to micro-movements in aggressive biological fluids. Titanium is widely used as an implant material ...

Electrochemical treatment of waste solutions containing ferrous sulfate by anodic oxidation using an undivided reactor
(Springer, 2000-12)
This paper describes an analysis of the performance of an electrochemical undivided reactor for the recycling of waste solutions containing ferrous sulfate. The effect of oxygen evolution as side anodic reaction on the ...
Anodização processada por corrente contínua e pulsada de uma liga al-si 6,75% tratada termicamente
(2010-12-01)
The purpose of this work was to find a heat treatment process to Al-6.75% Si alloy that makes the dispersion of Si element in order to overcome the difficulties in the anodizing process. Samples were put in an oven at 540°C ...
