The effect of surface roughness on the transfer of polymer films under unlubricated testing conditions
(Elsevier, 2015-03)
Blended Polyetheretherketone (PEEK) and polyimide-based polymers are excellent lighter tribomaterials that make possible the replacement of sliding metallic components in machinery. In this work a quantitative analysis of ...
Unraveling the origin of the Andean IOCG clan: A Re-Os isotope approach
(Elsevier, 2017)
The Andean IOCG clan in the Coastal Cordillera of northern Chile, comprises the iron oxide-Cu-Au sensu stricto,
the iron oxide-apatite (IOA), and the stratabound Cu(-Ag) deposits, also known as Manto-type Cu(-Ag) ...

Synthesis of high-density polyethylene/rGO-CNT-Fe nanocomposites with outstanding magnetic and electrical properties
(John Wiley, 2017)
Semi-conducting polyethylene (PE) nanocomposites with outstanding magnetic properties at room temperature were synthesized.
These exceptional properties, for a diamagnetic and insulating matrix as PE, were obtained by ...
Enhancement of the catalytic activity of fe phthalocyanine for the reduction of O 2 anchored to Au(111) via conjugated self-assembled monolayers of aromatic thiols as compared to Cu phthalocyanine
(2012)
We have prepared self-assembled monolayers (SAMs) of 4-aminothiophenol (4-ATP) and 1-(4-mercaptophenyl)-2,6-diphenyl-4-(4-pyridyl)pyridinium tetrafluoroborate (MDPP) functionalized with iron phthalocyanine (FePc) and copper ...
The Role of Solar Energy (UV-VIS-NIR) as an Assistant for Sulfide Minerals Leaching and Its Potential Application for Metal Extraction
(MDPI, 2021)
The mining industry is facing emerging challenges as a result of the increase in energy
consumption and environmental demands. These facts have promoted the use of renewable energy
sources, such as wind, geothermal and, ...
