Mercury distribution in a toposequence of sub-Antarctic forest soils of Tierra del Fuego (Argentina) as consequence of the prevailing soil processes
(Elsevier Science, 2014-11)
The total content, distribution and assessment of Hg sources in five soils of a toposequence of sub-Antarctic forest soils in Tierra del Fuego were explained as a combination of pedogenetic processes and the interactions ...
Room-temperature photoluminescence in amorphous SrTiO3-The influence of acceptor-type dopants
(2002-11-01)
Room-temperature photoluminescence (PL) was observed in undoped and 2 mol% Cr-, Al- and Y-doped amorphous SrTiO3 thin films. Doping increased the PL, and in the case of Cr significantly reduced the associated PL wavelength. ...
Factors affecting phosphorus sorption in loess soils of the semiarid Argentina
(Pisa University Press, 2000-08)
Previous results showed that phosphorus sorption strongly correlated with contents of active Al and Fe oxides and organic matter (OM) in soils of the-Semiarid Argentinean Pampas. Objective of this study was to determine ...
The use of Nb in rapid solidified Al alloys and composites
(Elsevier, 2013-12)
The worldwide requirements for reducing the energy consumption and pollution have increased the demand of new and high performance lightweight materials. The development of nanostructured Al-based alloys and composites is ...
Assessment of non-conventional pretreatments for agriculture wastes utilization
(2015)
Los pretratamientos convencionales de biomasa lignocelulósica involucran el uso intensivo de altas temperaturas, presiones, largos tiempos de residencia sumado a los requerimientos de productos químicos y los elevados ...
