Adsorptive behavior of multi-walled carbon nanotubes immobilized magnetic nanoparticles for removing selected pesticides from aqueous matrices
(Elsevier Ltd., 2023)
The present work synthesized two new materials of functionalized multi-walled carbon nanotubes (MWCNT–OH and MWCNT–COOH) impregnated with magnetite (Fe3O4) using solution precipitation methodology. The resulting MWCNT–OH–Mag ...
Terrestrial nanoparticle contaminants and geospatial optics using the Sentinel-3B OLCI satellite in the Tinto River estuary region of the Iberian Peninsula
(Elsevier Inc., 2023)
The Tinto River is known globally for having a reddish color due to the high concentration of dissolved metals in its waters. The general objective of this study is to analyze the dispersion of nanoparticles (NPs) and ...
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 ...
Study Of Coal Cleaning Rejects By FIB And Sample Preparation For HR-TEM: Mineral Surface Chemistry And Nanoparticle-Aggregation Control For Health Studies
(Journal Of Cleaner Production, 2018-04-05)
Nano-minerals and amorphous nanoparticles play a vital role in the contexts of human health and environmental sustainability. For instance, aerosols generated by the process of coal beneficiation adversely affect human ...
Ambient Nanoparticles/Nanominerals And Hazardous Elements From Coal Combustion Activity: Implications On Energy Challenges And Health Hazards
(Geoscience Frontiers, 2018-05)
Coal is the most abundant fossil fuel in the world. Because of the growth of coal mining, coal-fired power plants and coal-burning industries, the increase of the emission of particulates (coarse, fine or ultrafine) is of ...
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 ...
Nanoparticles containing hazardous elements and the spatial optics of the Sentinel-3B OLCI satellite in Amazonian rivers: a potential tool to understand environmental impacts
(Springer Science + Business Media, 2023-05-17)
The Amazon River is the longest river in the world. The Tapajós River is a tributary to the Amazon. At their junction, a marked decrease in water quality is evident from negative impacts from the constant activity of ...
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 ...
Environmental evaluation and nano-mineralogical study of fresh and unsaturated weathered coal fly ashes
(Science of the Total Environment, 2019-01-24)
Coal combustion and the disposal of combustion wastes emit enormous quantities of nano-sized particles that
pose significant health concerns on exposure, particularly in unindustrialized countries. Samples of fresh ...
