Mineralogy and geochemistry of the platinum group elements (PGE), rare earth elements (REE) and scandium in nickel laterites

Aiglsperger, Thomas Hans (Date of defense: 2015-12-17)

Ni laterites are considered worthy targets for critical metals (CM) exploration as rare earth elements (REE), Sc and platinum group elements (PGE) can be concentrated during weathering as a result of residual and secondary ...

Multi-isotopic and statistical approaches to trace nitrate pollution sources and assess natural attenuation in groundwater: examples from nitrate vulnerable zones in Catalonia (NE Spain)

Puig Caminal, Roger (Date of defense: 2014-05-19)

In the last decades, anthropogenic inputs of nitrogen to groundwater have dramatically increased, and they nowadays represent one of the most important water resources concerns as NO3-N has become the most ubiquitous ...

Natural and Induced Nitrate Attenuation Processes in Pétrola Basin (Albacete, Spain)

Carrey Labarta, Raúl (Date of defense: 2014-05-05)

One of the main problems of diffused groundwater contamination is produced by nitrate (NO3‾). NO3‾ pollution is linked with fertilizer application, manure management and wastewater. Many areas of Spain have NO3‾ concentration ...

Polymorphism and Solid State Miscibility of Triacylglycerols. Application to Food Authentication

Bayés-García, Laura (Date of defense: 2013-07-10)

Esta tesis se basa fundamentalmente en el estudio in situ del polimorfismo de triacilgliceroles (TAGs) mayoritarios de aceites y grasas alimentarios, la determinación del comportamiento de fases de algunas de sus mezclas ...
