Nanoparticles generated during volcanic rock exploitation: an overview
(Corporación Universidad de la Costa, 2021)
Nanoparticles (NPs) from the mining of volcanic rocks have been a matter of concern around the world because they can pose environmental and human health risks. The nanoparticles are pointed as opportunities of application ...
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 ...
Highly effective adsorption of synthetic phenol effluent by a novel activated carbon prepared from fruit wastes of the Ceiba speciosa forest species
(Corporación Universidad de la Costa, 2021)
Fruit wastes of the Ceiba speciosa forest species were employed as raw material for preparing activated carbon towards removing phenol from water. Concave cavities spread over the entire material surface were observed from ...
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 ...
Release kinetics of multi-nutrients from volcanic rock mining by-products: Evidences for their use as a soil remineralizer
(Corporación Universidad de la Costa, 2021)
Great quantities of stone by-products are stored alongside different exploiting mines in south Brazil, which are becoming an unsustainable environmental issue. Powder materials of andesite and dacite rocks were obtained ...
Biophysical matter in a marine estuary identified by the Sentinel-3B OLCI satellite and the presence of terrestrial iron (Fe) nanoparticles
(Corporación Universidad de la Costa, 2021)
The analysis of marine matter using the Sentinel-3B OLCI (Ocean Land Color Instrument) satellite is the most advanced technique for evaluating: the absorption of colored detrital and dissolved material (ADG_443_NN), total ...
Possibilities of using silicate rock powder: an overview
(Corporación Universidad de la Costa, 2021-03-11)
This study evaluates the on use of crushed rocks (remineralizers) to increase soil fertility levels and which contributed to increase agricultural productivity, recovery of degraded areas, decontamination of water, and ...
Nanoparticles as vectors of other contaminants in estuarine suspended sediments: natural and real conditions
(Corporación Universidad de la Costa, 2021)
Studding the behaviour and danger of nanoparticles (NPs, minerals and amorphous phases) in the estuarine ecosystem is presently incomplete by the lack of measureable description of NPs in the ecological conditions, such ...
The role of roots plants and soil characteristics in coal mining areas: geochemical and nanomineralogy information still without details
(Corporación Universidad de la Costa, 2021)
In worldwide coal mining, the rejects have a smaller particle size, which ends up favoring the concentration of toxic elements and oxidative potential of the respirable fraction of powdered mined coals. Evidence of the ...
Geotechnologies applied to the analysis of buildings involved in the production of poultry and swine to the integrated food safety system and environment
(Corporación Universidad de la Costa, 2021)
Initiatives to promote food security in relation to reducing food waste are of relevant for sustainability on a global scale. Rural buildings involved in the production of poultry and swine, in an integrated system tend ...
