First-principles study of Cd impurities localized at and near the (001) α-Al2O3 surface
(Elsevier Science, 2015-05)
Abstract A combination of two first-principles electronic structure calculation methods in the framework of density-functional theory was applied to investigate the (001) α-Al2O3 surface reconstruction and its structural, ...
Characterization of bone substitute β-TCP block for maxillofacial reconstruction Caracterización del bloque β-TCP de sustitución ósea para la reconstrucción maxilofacial
(Universidad de la Frontera, 2019)
The aim of this study was to characterize a commercial beta tricalcium phosphate (β-TCP) block allograft for use in maxillofacial reconstruction, evaluating its homogeneity, porosity and mineralization. Two commercial 5 x ...
A reconstruction of objets by interferometric profilometry with positioning system of labeled target periodic
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-03-01)
A method to extract 3D information using a white light interferometer without using PZT is presented. Instead a positioning system that uses the phase sensitivity of a target periodic is employed. The image treatment ...
Climate precursors of multidecadal drought variability in the western United States
(2004-12-07)
Low-frequency (periodicities lower than 20 years) hydrologic variability in the western United States over the past 500 years is studied using available tree-ring reconstructions of Palmer Drought Severity Index (PDSI), ...
Timing and extent of late pleistocene glaciation in the arid central andes of Argentina and Chile (22°-41°s)
(Universidad de La Rioja, 2017-07)
The arid Central Andes are a key site to study changes in intensity and movement of the three main atmospheric circulation systems over South America: the South American Summer Monsoon (SASM), the Westerlies and the El ...
Adhesive Bonding of Resin Composite to Various Ni-Cr Alloy Surfaces Using Different Metal Conditioners and a Surface Modification System
(Wiley-Blackwell, 2009-12-01)
Purpose: This study evaluated the effect of three metal conditioners [Metal Photo Primer (R) (MPP), Cesead II Opaque Primer (R) (OP), Targis Link (R) (TL)], and one surface modification system [Siloc (R) (S)] on the shear ...
Surface rearrangement of nanoscale zerovalent iron: the role of pH and its implications in the kinetics of arsenate sorption
(2014)
We consider the use of metallic iron nanoparticles for cleaning contaminated water, focusing our study in the sorption of arsenic compounds. In particular, we discuss the results of their sorption process on the surface ...
