Civancik-Uslu, Didem (Date of defense: 2019-05-16)
Mineral masterbatches, in other words mineral fillers, are concentrates of calcium carbonate or talc in a polymer base. In addition to their optimal cost, their use improves mechanical properties of materials and reduce ...
Cerro Gálvez, Elena (Date of defense: 2019-09-19)
Increasing amounts of organic synthetic chemicals are currently emitted to the environment by human activities. The more recalcitrant fraction of this pollutant mixture reaches marine ecosystems mainly through rivers, ...
Benveniste Pérez, Gabriela (Date of defense: 2021-03-05)
The continuous and expected increase of electrification in the transport sector, the so-called "electromobility" revolution, is one of the main drivers of progress in energy storage for vehicle propulsion. Today's electric ...
Rivas Becerra, Daniel (Date of defense: 2017-11-20)
Water is essential for life, human activities and ecosystems. The global climate change together the population increase causes an imbalance between the demand of water and the available water resources.. All these factors ...
Obiso, Vincenzo (Date of defense: 2018-03-07)
In this thesis an assessment of the parameterization of the Aerosol-Radiation Interaction (ARI) in online integrated meteorology-chemistry models has been conducted. The model estimates of ARI radiative effects are still ...
Martínez Varela, Alícia (Date of defense: 2022-04-29)
Increasing quantities of organic pollutants (OP) are being released to the environment, posing a threat to Earth’s life system. In the marine environment, OP pollution caused by oil spill accidents receives a lot of academic ...
Acevedo Dudley, Melissa Judith (Date of defense: 2016-10-24)
Over the last years, the sightings of the cubomedusa Carybdea marsupialis have increased in the Mediterranean Sea and this has been linked to an increase in its abundance. Consequently, this phD thesis addresses some ...
Lanko, Iryna (Date of defense: 2022-01-27)
Anaerobic digestion (AD) is currently spread all over the world for sewage sludge stabilisation, volume reduction and green energy production. Its implementation contributes to turn a wastewater treatment plant (WWTP) into ...
Aznar Alemany, Òscar (Date of defense: 2017-11-20)
During the last couple of decades the demand for good quality water in sufficient quantity has increased. The administration is now aware that water is not a commercial product; that hydrological management needs to be ...

Aquesta tesi doctoral investiga els processos clau que controlen la mobilitat d'alguns dels radionúclids sensibles al redox presents en els residus (U, Pu i Tc) i Ni com a radionúclid crític, en el repositori “Swedish Final ...
Cornejo Castillo, Francisco Miquel (Date of defense: 2017-12-19)
Biological N2 fixation, the reduction of dinitrogen (N2) gas to biologically available nitrogen, is a fundamental process since it represents a source of new nitrogen for marine life in areas where this important element ...
Grinyó Andreu, Jordi (Date of defense: 2016-10-17)
Technological development and increased availability of remotely operated vehicles and manned submersibles have significantly increased accessibility to deep environments revealing the presence of rich and diverse macrobenthic ...
Marín Beltrán, Isabel (Date of defense: 2017-07-21)
The Mediterranean Sea is an oligotrophic basin, while the atmosphere above is affected by continuous emissions of anthropogenic aerosols and episodic Saharan dust events. These atmospheric inputs finally deposit (as wet ...
Rodríguez Rey, Daniel (Date of defense: 2022-03-21)
Persistent high levels of NO2 have severe health effects on population. These are often found in large urban conurbations with high vehicle densities. In Barcelona, with one of the highest vehicle densities in Europe, the ...
