Mineralization of formic acid from catalytic nitrate reduction effluent by UV-based and electrochemical processes
(Elsevier, 2020-10)
In this work, UV-based and electrochemical processes were proposed for formic acid (FA) mineralization, from an effluent generated on the nitrate catalytic reduction reaction. The results show that although direct photolysis ...
Oxidation state characterization in Cr oxides by means of Cr Kb emission spectroscopy
(Elsevier, 2010-02)
High resolution Kb spectra of Cr oxide were measured using a non-conventional spectrometer. Theoretical spectra were obtained using the DV-Xa method in order to interpret the Kb spectrum structures. Kb spectrum structures ...

Influence of addition of calcium oxide on physicochemical properties of Portland cement with zirconium or niobium oxide
(2015)
Context: Calcium oxide (CaO) may be added to mineral trioxide aggregate (MTA) or Portland cement (PC) to improve physicochemical and biological properties. Aims: To evaluate the physicochemical properties of PC associated ...
Estudo da dissolução oxidativa microbiológica de uma complexa amostra mineral contendo pirita (FeS2), pirrotita (Fe 1-XS) e molibdenita (MoS2)
(2007-09-01)
This work aims to study the oxidation of a complex molybdenite mineral which contains pyrite and pyrrotite, by Acidithiobacillus ferrooxidans. This study was performed by respirometric essays and bioleaching in shake flasks. ...
