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 ...
Acute exposure to C60 fullerene damages pulmonary mitochondrial function and mechanics
(Corporación Universidad de la Costa, 2020-11-28)
C60 fullerene (C60) nanoparticles, a nanomaterial widely used in technology, can offer risks to humans, overcome biological barriers, and deposit onto the lungs. However, data on its putative pulmonary burden are scanty. ...
COVID-19 mortality and exposure to airborne PM2.5: a lag time correlation
(Corporación Universidad de la Costa, 2020-02-01)
COVID-19 has escalated into one of the most serious crises in the 21st Century. Given the rapid spread of SARS-CoV-2 and its high mortality rate, here we investigate the impact and relationship of airborne PM2.5 to COVID-19 ...
Multianalytical approach of stay-in-place polyvinyl chloride formwork concrete exposed to high temperatures
(Universidad de la Costa, 2020-03-31)
This work presents results of the first study of the variation by exposure to high temperatures from two stay-in-place polyvinyl chloride (SIP-PVC) formwork concrete exposed to the ISO 834 fire curve. A systematic sampling ...
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 ...
Analysis of the influence of thickness on fire reaction performance in polyisocyanurate core sandwich panels
(Corporación Universidad de la Costa, 2020)
Sandwich panels (also known as insulated panels) have been traditionally used for industrial buildings and warehouses, but nowadays are being increasingly a favorable choice in building construction, mainly in wall cladding ...
Adsorption of ibuprofen, ketoprofen, and paracetamol onto activated carbon prepared from effluent treatment plant sludge of the beverage industry
(Corporación Universidad de la Costa, 2020-09-15)
The presence of emerging contaminants such as pharmaceuticals in aquatic means presents as a serious threat, since their real consequences for the environment and human health are not well known. Therefore, this work ...
