Density functional theory study of water interactions on Mn-doped CeO2(1 1 1) surface
(Elsevier Science, 2014-06)
Spin-polarized density functional theory (DFT + U) periodic calculations have been performed to study water adsorption and dissociation on the 12.5% Mn-doped CeO2(1 1 1) surface. Our results indicated that Mn cation is the ...
An analysis of the effects of nanoparticles deposition on characteristics of the heating surface and ON pool boiling of water
Nanofluid pool boiling can modify the morphology of the heating surface and the physical properties of the base fluids, interfering directly on the vapor bubbles dynamics and on the heat transfer mechanisms. This paper ...
Investigations on the stability of plasma modified silicone surfaces
(Kluwer Academic/plenum Publ, 2004-03-01)
In this work it was investigated the effect of the exposure to different plasmas on the wettability of silicone samples. We have observed that oxygen. argon, and hydrogen glow discharges are quite effective in reducing the ...
Surface water and groundwater response to the tide in coastal wetlands: Assessment of a marsh in the outer Río de la Plata estuary, Argentina
(Coastal Education & Research Foundation, 2013-03)
On the coast of the outer Río de la Plata estuary (Argentina) there is a vast coastal wetland occurring in a marsh environment. The hydrodynamics of this wetland is subject to a semidiurnal microtidal regime which causes ...
Some reflections on the future of the water quality of the corumbataí River basin, São Paulo state, Brazil
The waters of Corumbataí River in the middle and eastern part of São Paulo State, Brazil, are extensively used for human consumption; their water quality has been modified mainly due to increasing pressure caused by ...
