Nanoparticles and interfaces with toxic elements in fluvial suspended sediment
(Universidad de la Costa, 2021)
Studies examining nanoparticles (NPs) and hazardous elements (HEs) contained in suspended sediments (SSs) are vital for watershed administration and ecological impact evaluation. The biochemical consequence of titanium-n ...
Sustainable release of macronutrients to black oat and maize crops from organically-altered dacite rock powder
(Corporación Universidad de la Costa, 2021)
By-products from the dairy industry and mining activities represent a great environmental overload, which justify research for value-added reuse of these by-products (dairy sludge and dacite rock powder). Dairy sludge is ...
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 ...
Efficient removal of naproxen from aqueous solution by highly porous activated carbon produced from Grapetree (Plinia cauliflora) fruit peles
(Corporación Universidad de la Costa, 2021)
In this work, jabuticaba (Plinia cauliflora) fruit peels were pyrolyzed in the presence of zinc chloride to generate a novel porous adsorbent to remove naproxen (NPX) from aqueous solutions. The maximum adsorption capacity ...
Application of Andesite Rock as a Clean Source of Fertilizer for Eucalyptus Crop: Evidence of Sustainability
(Universidad de la Costa, 2020-02-05)
Global demineralization of agricultural soils due to unsustainable use of highly soluble fertilizers and intensive exploitation is an issue of increasing concern. Methods of remineralization include the application of ...
Nanominerals assemblages and hazardous elements assessment in phosphogypsum from an abandoned phosphate fertilizer industry
(Universidad de la Costa, 2020)
The present work investigates hazardous elements and nanomineralogical assemblages of phosphogypsum waste from an abandoned phosphate fertilizer industry located in Santa Catarina state (Brazil). Correlations between the ...
Formation of carbon quantum dots and graphene nanosheets from different abundant carbonaceous materials
(Universidad de la Costa, 2020-03-20)
Carbon quantum dots (CQDs) and graphene nanosheets (GNs) are one of the most attractive fluorescent carbon nano-sized materials with unique features of optical and physico-chemical properties having various applications ...
Understanding the mobility of potential nutrients in rock mining by-products: An opportunity for more sustainable agriculture and mining
(Universidad de la Costa, 2020-03-25)
The increase in demand for highly soluble fertilizers brings a global sustainability concern. Alternative sources for traditional fertilization are therefore needed. Rock powder use has been proposed as an alternative ...
Incidence of lung cancer and mortality among civil construction industry workers: A protocol for a systematic review and meta-analysis
(Corporación Universidad de la Costa, 2021-04-26)
The construction sector is one of the most stable growth industries in the world. However, many studies have suggested an association between occupational exposure in civil construction and lung cancer risk. Thus, this ...
Transforming shrub waste into a high-efficiency adsorbent: Application of Physalis peruvian chalice treated with strong acid to remove the 2,4-dichlorophenoxyacetic acid herbicide
(Corporación Universidad de la Costa, 2021)
In this study, the chalice generated from the production of the Physalis peruviana fruit was subjected to a treatment with sulfuric acid and applied in the adsorption of 2,4-Dichlorophenoxyacetic acid (2,4-D). The precursor, ...
