Plasma electrolytic oxidation up to four-steps performed on niobium and Nb-Ti alloys
(2022-05-25)
Plasma electrolytic oxidation (PEO) of up to four steps were performed on Niobium (Nb), and binary Niobium-Titanium alloys (Nbx-Ti, x = 50%, 90 wt.%), and the resulting oxidized surfaces were compared to their respective ...
Chemical evolution in the Asteraceae. The Oxidation-Reduction mechanism and production of secondary metabolites
(Natural Products Inc, 2006-01-01)
This work describes the application of partial least squares (PLS) regression to variables that represent the oxidation data of several types of secondary metabolite isolated from the family Asteraceae. The oxidation states ...

Oxide coating containing apatite formed on Ti-25Nb-25Ta alloy treated by Two-Step Plasma Electrolytic Oxidation
(Elsevier B.V., 2020-01-25)
Hydroxyapatite (HA) is a bioactive calcium phosphate capable of enhancing the implant/bone connection improving osteoconductivity and osseointegration process. However, the HA presents mechanical properties limiting its ...
The role of the steps in the cleavage of the C-C bond during ethanol oxidation on platinum electrodes
(ROYAL SOC CHEMISTRY, 2009)
Ethanol oxidation has been studied on stepped platinum single crystal electrodes in acid media using electrochemical and Fourier transform infrared (FTIR) techniques. The electrodes used belong to two different series of ...
Step-by-step synthesis of iron-oxide nanoparticles attached to graphene oxide: A study on the composite properties and architecture
(Pergamon-Elsevier Science Ltd, 2018-11)
A set of nanocomposites made of iron oxide nanoparticles covalently bonded to graphene oxide and reduced graphene oxide was successfully prepared. The synthesis was carried out in a precise step-by-step process in order ...
Tribocorrosion behaviour of bio-functionalized porous Ti surfaces obtained by two-step anodic treatment
(2020-04-15)
A bio-functionalized porous surface was obtained on Ti by a two-step anodic treatment and its corrosion and tribocorrosion behaviour were evaluated. The first-step provided macro-porosity while the second-step, a ...
Spectroelectrochemical analysis of HOPG surface controlled modification
(Elsevier Science, 2017-04-14)
In situ Raman spectroscopy is used to characterize the changes induced by electrochemical oxidation and silver electrodeposition at the step-edge and terrace sites of highly-oriented pyrolytic graphite (HOPG) surfaces. Ag ...
