Soft or Hard? Investigating the Deformation Mechanisms of Au-Pd and Pd Nanocubes under Compression: An Experimental and Molecular Dynamics Study
(AMER CHEMICAL SOC, 2021-11-18)In the search for new mechanisms to improve and control the mechanical properties of nanostructures, the idea of tuning the strength through composition is appealing because of the extensive experimental availability of ... -
Soil bacterial community structure of fog-dependent Tillandsia landbeckii dunes in the Atacama Desert
(SPRINGER WIEN, 2021-09-06)The interplay between plants and soil drives the structure and function of soil microbial communities. In water-limited environments where vascular plants are often absent and only specialized groups of rootless plants ... -
Soil contamination in nearby natural areas mirrors that in urban greenspaces worldwide
(NATURE PORTFOLIO, 2023-03-27)Soil contamination is one of the main threats to ecosystem health and sustainability. Yet little is known about the extent to which soil contaminants differ between urban greenspaces and natural ecosystems. Here we show ... -
Soil microbial abundance and activity across forefield glacier chronosequence in the Northern Patagonian Ice Field, Chile
(Chile. Universidad Mayor, 2020)In recently deglaciated soils, microbial organisms drive soil transformations by increasing carbon (C) and nitrogen (N) pools while depleting available phosphorous (P), thus improving plant colonization and soil development. ... -
Sources and diffusive air-water exchange of polycyclic aromatic hydrocarbons in an oligotrophic North-Patagonian lake
(Elsevier, 2020-10)Polycyclic aromatic hydrocarbons (PAHs) are semivolatile organic compounds of environmental concern. This study aims to investigate the influence of local sources of anthropogenic PAHs and their air-water exchange fluxes ... -
Spatial and Temporal Variability in the Development and Potential Toxicity of Phormidium Biofilms in the Tarn River, France
(MDPI, 2018)Proliferation of Phormidium biofilms in rivers is becoming a worldwide sanitation problem for humans and animals, due to the ability of these bacteria to produce anatoxins. To better understand the environmental conditions ... -
Spatial distribution and interannual variability of coastal fog and low clouds cover in the hyperarid Atacama Desert and implications for past and present Tillandsia landbeckii ecosystems
(SPRINGER WIEN, 2021-10)The hyperarid Atacama Desert coast receives scarce moisture inputs mainly from the Pacific Ocean in the form of marine advective fog. The collected moisture supports highly specialized ecosystems, where the bromeliad ... -
Spatial inequality and aspirations for economic inclusion among Latin American youth
(Elsevier, 2020-11)Youths' aspirations formation is typically analysed in its association with individual, family and school characteristics. This paper adopts a wider perspective and uses descriptive and econometric analysis to investigate ... -
Spatio-temporal variation of the strain field in the southern Central Andes broken-foreland (27 degrees 30 ' S) during the Late Cenozoic
(Elsevier BV, 2021-03)We present an integrated structural and Anisotropy of Magnetic Susceptibility (AMS) study focused on the characterization of the spatio-temporal variation of the strain field during the main Neogene deformation, of the ... -
Spatio-Temporal Variation of the Urban Heat Island in Santiago, Chile during Summers 2005-2017
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)Urban heat islands (UHIs) can present significant risks to human health. Santiago, Chile has around 7 million residents, concentrated in an average density of 480 people/km(2). During the last few summer seasons, the highest ... -
Species traits and network structure predict the success and impacts of pollinator invasions
(NATURE PUBLISHING GROUP, 2018)Species invasions constitute a major and poorly understood threat to plant-pollinator systems. General theory predicting which factors drive species invasion success and subsequent effects on native ecosystems is particularly ... -
Spectral intensities in trivalent lanthanide systems: Applications to the Cs2NaDyCl6 and Cs2NaHoCl6 crystals
(, 2008-08-11)The main goal of this research work is to rationalize the rich vibronic structure of lanthanide type crystals, such as Cs2NaDyCl6 and Cs2NaHoCl6, in the space group Fm3m(Oh5). These systems are known to be highly relativistic ... -
Spectroscopic and photometric study of the eclipsing interacting binary V495 Centauri
(OXFORD UNIV PRESS, 2018)Double Periodic Variables (DPV) are among the new enigmas of semidetached eclipsing binaries. These are intermediate-mass binaries characterized by a long photometric period lasting on average 33 times the orbital period. ... -
Spin-lattice dynamics of surface vs core magnetization in Fe nanoparticles
(AIP Publishing, 2021-07-05)Magnetization of clusters is often simulated using atomistic spin dynamics for a fixed lattice. Coupled spin-lattice dynamics simulations of the magnetization of nanoparticles have, to date, neglected the change in the ... -
Spin-lattice-dynamics analysis of magnetic properties of iron under compression
(NATURE PORTFOLIO, 2023-08-31)Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous ... -
Spirometric values in healthy preschool children
(SOC CHILENA PEDIATRIA, 2019)Introduction. Spirometry is the most commonly used test to evaluate lung function. Foreign reference standards are currently available for preschool children. Objectives: 1. To measure spirometric variables in healthy ...
