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 ...
Nanometric particles of high economic value in coal fire region: Opportunities for social improvement
(Universidad de la Costa, 2020-02-10)
Spontaneous coal combustion in the La Guajira coals was studied for the presence of carbon nanophases (e.g., carbon nanotubes), occurrence of rare earth elements (REEs) in them, and the probable mechanisms for concentration ...
Occurrence of carbon nanotubes and implication for the siting of elements in selected anthracites
(Universidad de la Costa, 2020-03-01)
Petrographic, geochemical, and electron microbeam investigations of selected anthracites and anthracite-rank coaly shales were conducted. The Pennsylvania, Rhode Island, and KwaZu-Natal anthracites show an enrichment in ...
Atmospheric nanocompounds on lanzarote island: vehicular exhaust and igneous geologic formation interactions
(Universidad de la Costa, 2020-04-28)
Atmosphere contamination management is one of the most important features in pollution risk management. The worldwide rise in tourism increases apprehension about its probable destructive conservation influence on various ...
A three-dimensional nanoscale study in selected coal mine drainage
(Universidad de la Costa, 2020-01-28)
Sediments from coal mine drainages (CMDs) contain large quantities of suspended pollutants (possibly numerous chemical substances) along with sulfates and hazardous elements (e.g., chromium, zinc, copper, lead) that ...
