Mineralogy of the Chaparra IOCG deposit, southern Peru
(European Geosciences Union (EGU), 2014)
Comunicació de congrés
Accés obertThe Chaparra IOCG, located in southern Peru, near Chala, is mined and exploited by small-scale miners for gold, however, it has not been studied until now. Here we present a preliminary geological and mineralogic study of ... -
Mineral assemblages in the tin (-indium) Santa Fe mining district, Bolivia
(2016)
Comunicació de congrés
Accés obertThe Santa Fe Mining District (SFD) is located in the Bolivian portion of the Central Andean Belt, which is an important tin province that hosts abundant world-class deposits, some of them with high indium content. In this ... -
Macro talent management in Spain: Is the sun rising again?
(Routledge, 2018-07-18)
Capítol de llibre
Accés restringit per política de l'editorialMacro talent management incorporates activities aimed at attracting, mobilizing, developing, and retaining top talent within an organization. As such, it has also major implications for organizations, including multinational ... -
Flexoelectric MEMS: towards an electromechanical strain diode
(2016)
Article
Accés obertPiezoelectricity and flexoelectricity are two independent but not incompatible forms of electromechanical response exhibited by nanoscale ferroelectrics. Here, we show that flexoelectricity can either enhance or suppress ... -
Mineralogy of the Santa Fe tin deposit, Bolivia
(European Geosciences Union (EGU), 2014)
Comunicació de congrés
Accés obertSanta Fe is a Sn-Zn-Pb-Ag ore deposit located in the Oruro district, Central Andean Tin Belt, Bolivia. Mineralization occurs in veins and disseminations. It is hosted in Silurian shales and greywackes. The sedimentary ... -
Reducing Interface Recombination through Mixed Nanocrystal Interlayers in PbS Quantum Dot Solar Cells
(ACS, 2017-08-08)
Article
Accés restringit per política de l'editorialThe performance of ZnO/PbS colloidal quantum dot (CQD)-based heterojunction solar cells is hindered by charge carrier recombination at the heterojunction interface. Reducing interfacial recombination can improve charge ... -
Mineralogy and geochemistry of the IRG Misky gold deposit, southern Peru
(European Geosciences Union (EGU), 2014)
Comunicació de congrés
Accés obertThe Misky gold deposit is one of the several Intrusion Related gold deposits that occur in the ocoña river basin, southern Peru. They are hosted in magmatic rocks from the Nazca-Palpa-Ocoña belt, from the Coastal Batholith. In ... -
A flexoelectric microelectromechanical system on silicon
(2016)
Article
Accés obertFlexoelectricity allows a dielectric material to polarize in response to a mechanical bending moment and, conversely, to bend in response to an electric field. Compared with piezoelectricity, flexoelectricity is a weak ... -
MoS2-HgTe Quantum Dot Hybrid Photodetectors beyond 2 µm
(Wiley, 2017-05-03)
Article
Accés obertMercury telluride (HgTe) colloidal quantum dots (CQDs) have been developed as promising materials for the short and mid‐wave infrared photodetection applications because of their low cost, solution processing, and size ... -
Domesticating the Street (Rehabitar project)
(TU Delft, 2014)
Article
Accés obert -
Trap-state suppression and improved charge transport in PbS quantum dot solar cells with synergistic mixed ligand treatments
(Wiley, 2017-04-12)
Article
Accés obertThe power conversion efficiency of colloidal PbS‐quantum‐dot (QD)‐based solar cells is significantly hampered by lower‐than‐expected open circuit voltage (VOC). The VOC deficit is considerably higher in QD‐based solar cells ... -
Mercury pollution from the artisanal mining in Yani gold district, Northern Bolivia
(European Geosciences Union (EGU), 2016)
Comunicació de congrés
Accés obertArtisanal gold mining is the main economic activity in the Yani district, Northern Bolivia. In this area abundant orogenic gold deposits constituted by quartz veins hosted in paleozoic turbiditic series that contain either ...
