Decolorization and mineralization of Diarylide Yellow 12 (PY12) by photo-Fenton process: the Response Surface Methodology as the optimization tool.
(IWA PUBLISHING, 2012-01-01)
The Response Surface Methodology (RSM) was applied as a tool for the optimization of the operational conditions of the photo-degradation of highly concentrated PY12 wastewater, resulting from a textile industry located in ...
Changes in metabolic pathways of Desulfovibrio alaskensis G20 cells induced by molybdate excess
(Springer, 2015-03)
The activity of sulfate-reducing bacteria (SRB) intensifies the problems associated to corrosion of metals and the solution entails significant economic costs. Although molybdate can be used to control the negative effects ...
Colloidal sulphur production by electrochemical oxidation of sulphide in a swirling flow reactor
(Royal Society of Chemistry, 2021-10)
A cylindrical reactor with swirling flow is tested for the production of colloidal sulphur via the oxidation of sulphide ions with a concentration of 2 g dm−3 in alkaline solutions at 80 °C. Polysulphides are anodically ...

Seed-mediated growth of jack-shaped gold nanoparticles from cyclodextrin-coated gold nanospheres
(Royal Society of Chemistry, 2013-08)
Branched gold nanoparticles were prepared by a seed-mediated approach using per-6-thio-6-deoxy-β-cyclodextrin capped gold nanospheres as seeds and a growth medium similar to those commonly employed to prepare gold nanorods, ...
The involvement of transition metal ions on iron-dependent lipid peroxidation
(Springer, 2010-04)
The metals iron (Fe) and copper (Cu) are considered trace elements, and the metals cobalt (Co) and nickel (Ni) are known as ultra-trace elements, considering their presence in low to very low quantity in humans. The biologic ...
Differential effects of Zn concentrations on Cr(VI) uptake by two Salvinia species: involvement of thiol compounds
(Taylor & Francis, 2021-07)
Floating ferns of the genus Salvinia have great potential for phytoremediation of heavy metals. To date, the effect of essential metals on the accumulation and transport of toxic metals by aquatic ferns has not been suitably ...
