The nitrate deposits of the Atacama Desert are unique when one considers that in most surface environments nitrate is produced or consumed by biological processes and is easily washed away by rain. Nitrate deposits have ...

In this work we optimized conditions for aerosol deposition of homogeneous, nano-grained, smooth Ba0.8Sr0.2TiO3 thin films. Investigation involved optimization of deposition parameters, namely deposition time and temperature ...

We study the effects of time-dependent substrate/film temperature in the deposition of a mesoscopically thick film using a statistical model that accounts for diffusion of adatoms without lateral neighbors whose coefficients ...

A procedure is presented for quantification of sources contributing to atmospheric aerosol chemical nutrient concentrations and dry deposition fluxes. Source apportionment using principal component analysis (PCA) and ...

Hardgrounds are important surfaces for basin analysis and oil exploration, representing in some cases significant markers of the sedimentary basin fill. In the Neuquén Basin, bioerosion structures are common on the shell ...

Work is reported on the characterizations of pulsed laser deposited aluminum-nitride thin films. The films were deposited on silicon substrate with a KrF 248 nm pulse laser operating in a Riber LDM-22 system. Optical ...
