Effect of structural singularities on superwettability of SiO₂-based coatings
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2019-11-07)
A detailed study on the correlation between structural singularities and wettability of neat and chemically modified coatings prepared from layer-by-layer (LbL) assembled silica nanoparticles (SiO₂) was performed. ...
Um estudo da qualidade da água do rio dos Porcos: indícios de aprendizagem de conceitos científicos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação de Mestrado Profissional em Química - PPGQCâmpus São Carlos, 2020-02-27)
Chemistry teaching aims to establish relations with an approach in Science, Technology, Society and Environment, it is becoming more and more important and necessary nowadays. The school has the role of forming citizens ...
Strength assessment of Al-Humic and Al-Kaolin aggregates by intrusive and non-intrusive methods
(2019-06-15)
Resistance to breakage is a critical property of aggregates generated in water and wastewater treatment processes. After flocculation, aggregates should ideally keep their physical characteristics (i.e. size and morphology), ...
Macrophytes’ abundance changes in eutrophicated tropical reservoirs exemplified by Salto Grande (Brazil): Trends and temporal analysis exploiting Landsat remotely sensed data
(2020-08-01)
River damming for electric power production generally triggers a set of anthropic activities that strongly impact on aquatic ecosystem, especially in small reservoirs located in urbanized and industrialized areas. Among ...
Improved estimates of glacier change rates at Nevado Coropuna Ice Cap, Peru
(Cambridge University PressGB, 2018-04)
Accurate quantification of rates of glacier mass loss is critical for managing water resources and for assessing hazards at ice-clad volcanoes, especially in arid regions like southern Peru. In these regions, glacier and ...
Efficient screening method for determination of polycyclic aromatic hydrocarbons (PAHs) in airborne particles. Application in real samples of Santiago-Chile metropolitan urban area
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-05)
A rapid analytical approach for determination of polycyclic aromatic hydrocarbons (PAHs) present in real samples of particulate matter (PM10 filters) was investigated, based on the use of water under sub critical conditions, ...
Morphological evolution of the Maipo River in central Chile: Influence of instream gravelmining
(2018)
Instream gravel mining is one of the most important causes of channel degradation in South America, specifically in rivers located near large metropolitan areas with rapidly growing cities, where no river management ...
Meteorological Interpretation of Orographic Precipitation Gradients along an Andes West Slope Basin at 30 degrees S (Elqui Valley, Chile)
(2017)
To better forecast streamflow and water resource availability, it is important to have an understanding of the meteorological drivers of the orographic precipitation gradient (OPG), especially critical in semiarid mountainous ...
Synthesis and self-assembly study of zwitterionic amphiphilic derivatives of chitosan
(Wiley-Blackwell, 2016-11-20)
New zwitterionic derivatives of chitosan (CH) were synthesized through the Michael addition reaction of 1-(3-sulfopropyl)2-vinylpyridine hydroxide (SPP) with primary amines of deacetylated CHs (with weight-average molecular ...

(International Glaciological Society, 2007-10)
The energy balance of bare snow and tephra-covered ice near the glacier equilibrium line
elevation on Villarrica Volcano, southern Chile, was investigated during 2004 and 2005, combining
meteorological, surface temperature ...
