Isotopic Equilibrium Between Precipitation and Water Vapor in Northern Patagonia and Its Consequences on δ18Ocellulose Estimate
(Blackwell Publishing, 2020-02)
Modeling work of the isotopic composition of tree ring cellulose (δ18Ocell) relies on the isotopic equilibrium assumption between atmospheric water vapor and tree source water, frequently assimilated to integrated ...

Carbon and Hydrogen Isotopes as Tracers of Methane Dynamic in Wetlands
(Scientific Research Publishing, 2015-07)
This work presents a review of the main processes leading to the production and sinking of methane in wetlands and how they affect the stable isotope composition of carbon and hydrogen. Isotope fractionation factors ...
Carbon stable isotopes as indicators of the origin and evolution of CO2 and CH4 in urban solid waste disposal sites and nearby areas
(Springer, 2016-02)
Isotopic compositions of CH4 and CO2 surface and subsurface gases and groundwater from an urban solid waste disposal site from Gualeguaychú city (Argentina) were measured to detect origin, depth distribution, migration ...
Hydrogen isotopic substitution experiments in nanostructured porous silicon
(Elsevier Science Sa, 2008-12)
Nanostructured porous silicon is usually prepared by electrochemical anodization of monocrystalline silicon using a fluorine-rich electrolyte. As a result of this process, the silicon atoms conserve their original crystalline ...
