Confined benzene within InOF-1: Contrasting CO2 and SO2 capture behaviours
(Royal Society of Chemistry, 2020)Acceso restringidoThe confinement of small amounts of benzene in InOF-1 (Bz@InOF-1) shows a contradictory behavior in the capture of CO2 and SO2. While the capture of CO2 is increased 1.6 times, compared to the pristine material, the capture ... -
Efficiency of electrocoagulation method to reduce COD, BOD and TSS in tannery industry wastewater: Application of the box–behnken design
(Institutional National de Cercetare-Dezvoltare Pentru Texttile Pielarie, 2020)Acceso abiertoThis study intends to assess the removal efficiency of the chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total suspended solids (TSS) from raw tannery wastewater using electrocoagulation by aluminum ... -
Estimation of the impact of biomass burning based on regional transport of PM2.5 in the Colombian Caribbean
(Elsevier, 2022)Acceso abiertoDeterioration of air quality due to the increase in atmospheric emissions from biomass burning (BB) is one of the major environmental problems worldwide. In this study, we estimated the contributions of BB to PM2.5 ... -
Factorial design for preparing chitosan nanoparticles and its use for loading and controlled release of indole-3-acetic acid with effect on hydroponic lettuce crops
(International Society of Biocatalysis and Agricultural Biotechnology, 2020)Acceso restringidoThe excessive use of agrochemicals generates damage to the environment, so their controlled release from biodegradable nanoparticles represents a good solution. In this study, chitosan nanoparticles (CNPs) were prepared ... -
Geochemical study of submicron particulate matter (PM1) in a metropolitan area
(Elsevier, 2022)Acceso abiertoAir pollution has become a major problem in urban areas due to increasing industrialization and urbanization. In this study ambient concentrations of PM1 and metal concentrations as well as source contributions were ... -
Identification of hazardous nanoparticles present in the Caribbean Sea for the allocation of future preservation projects
(Elsevier, 2021)Acceso restringidoThe 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 ... -
Measurement and analysis of air quality in temporary shelters on three continents
(Elsevier, 2020)Acceso restringidoMillions of displaced people are housed in shelters that generally consist of a single room, meaning that activities including cooking, sleeping and socializing all take place in the same space. Therefore, indoor air quality ... -
Metal-enriched nanoparticles and black carbon: A perspective from the Brazil railway system air pollution
(Elsevier, 2021)Acceso abiertoHaving 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 ... -
La minería y los objetivos de desarrollo sostenible en los tiempos de la COVID-19
