Titanium nanoparticles in sedimented dust aggregates from urban children’s parks around coal ashes wastes
(Corporación Universidad de la Costa, 2021)
Recently, an increased interest in nanoscience applications can be observed in various fields. Soils around coal power plants may contain potentially hazardous elements (PHEs) and nanoparticles (NPs), which can be neo-produced ...
Air pollutants and their degradation of a historic building in the largest metropolitan area in latin america
(2021-03-14)
Historic buildings that comprise the cultural heritage of humanity are in need of preservation on a worldwide scale in regard to degradation resultant from atmospheric pollutants. The Brazilian Public Market, located in ...
Metal-enriched nanoparticles and black carbon: A perspective from the Brazil railway system air pollution
(Corporación Universidad de la Costa, 2021)
Having a better understanding of air pollutants in railway systems is crucial to ensure a clean public transport. This study measured, for the first time in Brazil, nanoparticles (NPs) and black carbon (BC) on two ground-level ...
Hazardous thoracic and ultrafine particles from road dust in a Caribbean industrial city
(Universidad de la Costa, 2020)
In this study, inorganic geochemical characterization of the thoracic (or < 10 μm) fraction of road dust in Barranquilla (a major industrial city in the Caribbean region) was conducted. Samples were collected directly from ...
Volcanic emissions and atmospheric pollution: a study of nanoparticles
(Corporación Universidad de la Costa, 2021-03)
The influence of emissions of an active volcano on the composition of nanoparticles and ultrafine road dust was identified in an urban area of the Andes. Although many cities are close to active volcanoes, few studies have ...
Artisanal ceramic factories using wood combustion: a nanoparticles and human health study
(Corporación Universidad de la Costa, 2021-01-31)
The ceramics industry, resulting from developments of modern compounds, is a segment of great influence in worldwide sustainability. Artisanal ceramic factories based on wood combustion have significant risks for the ...
The impact of air pollutants on the degradation of two historic buildings in Bordeaux, France
(Urban Climate, 2021)
Urban centers concentrate high levels of atmospheric pollutants, sourced by vehicular traffic, public transit systems, industrial emissions and agricultural emissions. This leads to the accumulation of gases and particulate ...
Identification of hazardous nanoparticles present in the Caribbean Sea for the allocation of future preservation projects
(Corporación Universidad de la Costa, 2021)
The deposition of remaining nanoparticles in the Caribbean Sea generates the formation of potentially dangerous elements, which influence at the imbalance of ecosystems. The detection of nanoparticles is not simple and the ...
New insights on enzyme stabilization for industrial biocatalysis
(American Chemical Society, 2021)
Due to their versatility and ability to provide tunable chemo-, regio-, and enantio-selectivitites, enzyme-mediated transformations offer an effective and eco-friendly alternative to the traditional multistep chemical ...
Dispersion of hazardous nanoparticles on beaches around phosphogypsum factories
(2021)
Anthropogenic occurring nanoparticles (NPs) have been one of the principal catalytic components of marine pollution throughout its history. The phosphogypsum (PG) factories present environmental risks and evident marine ...
