Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation: photocatalytic reduction of Cr(VI)
(Elsevier Science Sa, 2017-04)
Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200-3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ...
Photochemical reduction of U(VI) in aqueous solution in the presence of 2-propanol
(Elsevier Science Sa, 2014-03)
The efficiency of the photochemical reduction of uranyl (UO22+) (0.25 mM, pH 3) was analyzed in theabsence and in the presence of 2-propanol (2-PrOH), evaluating the effect of anions (nitrate, acetate andperchlorate) and ...

Exploiting electron storage in TiO2 nanoparticles for dark reduction of As(v) by accumulated electrons
(Royal Society Of Chemistry, 2013-05)
UV irradiation of an ethanolic sol of TiO2 nanoparticles produces a trapped Ti(III) centre and a noticeable Burstein shift. Direct evidence that the accumulated charges can drive the otherwise forbidden reduction of ...
Supplemental phytase derived from E. coli in different concentrations on performance, bone mineralization and cost of broilers diets
(2020-01-01)
The trial was conducted to evaluate the supplementation of E. coli phytase on performance, weight and ash of bones, as well as to determine the bioavailability of P and cost/benefit of its use in diets. A total 1,890 Cobb ...
Influence of anodizing variables on Cr(VI) photocatalytic reduction using TiO2 nanotubes obtained by anodic oxidation
(Elsevier Science, 2021-07)
The effect of growth conditions of TiO2 films with nanotubular structures produced by anodic oxidation in electrolytes containing NH4F in glycerol and water was investigated. The effect of anodizing voltage, time, NH4F ...

Mechanisms of removal of heavy metals and arsenic from water by TiO2-heterogeneous photocatalysis
(De Gruyter, 2015-06)
This article is an overview of recent work performed in our laboratory on TiO2 heterogeneous photocatalysis of aqueous systems containing toxic forms of chromium, arsenic, lead, uranium and mercury. The cases of chromium ...
Litter is more effective than forest canopy reducing soil evaporation in Dry Chaco rangelands
(John Wiley & Sons Inc, 2017-10)
Soil evaporation is a dominant water flux of flat dry ecosystems, reducing available water for plant transpiration. Vegetation plays a key role at controlling evaporation, especially by altering soil surface micro-meteorological ...
