Nitric oxide emission during the reductive heterogeneous photocatalysis of aqueous nitrate with TiO2
(Royal Society of Chemistry, 2015-10)
For the first time, nitric oxide (NO), a precursor of nitrogen dioxide (NO2, a NIOSH-listed atmospheric pollutant), has been found to be one of the final products of the photocatalytic reduction of nitrate in water using ...
Effect of different substrates on composting of poultry litter
(Sociedade Brasileira de Zootecnia, 2012-07-01)
The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The ...
Effect of different substrates on composting of poultry litter

The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The ...
Field exclusion of large soil predators impacts lower trophic levels and decreases leaf-litter decomposition in dry forests
(Wiley Blackwell Publishing, Inc, 2019-09-08)
Shifts in densities of apex predators may indirectly affect fundamental ecosystem processes, such as decomposition, by altering patterns of cascading effects propagating through lower trophic levels. These top–down effects ...
Effect of different gases on the sonochemical Cr(VI) reduction in the presence of citric acid
(Pergamon-Elsevier Science Ltd, 2020-12)
The sonochemical (850 kHz) Cr(VI) reduction (0.30 mM, pH 2) in the presence of citric acid (Cit, 2 mM) was analyzed under different working atmospheres: reactor open to air without sparging (ROAWS), and Ar, O2, air and N2 ...
Experimental Evidence in Favor of an Initial One-Electron-Transfer Process in the Heterogeneous Photocatalytic Reduction of Chromium(VI) over TiO 2
(American Chemical Society, 2001-06)
Direct evidence of the involvement of Cr(V) intermediacy in Cr(VI) heterogeneous photocatalytic reduction over TiO2 was obtained by EPR spectroscopy, in the presence and absence of ethylenediaminetetraacetic acid (EDTA). ...
Leaf litterfall, fine-root production, and decomposition in shrublands with different canopy structure induced by grazing in the Patagonian Monte, Argentina
(Springer, 2008-10)
Selective sheep grazing in the Patagonian Monte induces the reduction of total and perennial grass cover, species replacement within life forms, and the increase in dominance of long-lived evergreen woody plants with slow ...
Sonochemical reduction of Cr(VI) in air in the presence of organic additives: What are the involved mechanistic pathways?
(Elsevier Science, 2018-11)
The sonochemical (850 kHz) reduction of Cr(VI) (0.3 mM, pH 2, reactor open to air) was analyzed in the presence of different additives. The effects on Cr(VI) reduction efficiency of added formic acid (FA, 10 mM), citric ...
Litter microbial and soil faunal communities stimulated in the wake of a volcanic eruption in a semi-arid woodland in Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2017-01)
Large-scale disturbances can be important components of the temporal landscape of natural ecosystems, but generalities regarding ecosystem impacts are difficult due to their infrequent and unpredictable nature. Volcanic ...
