Homogeneous and heterogeneous aqueous phase oxidation of phenol with fenton-like processes
A les passades dècades, s’han desenvolupat diverses tècniques basades en l’oxidació química a fi de superar els inconvenients associats al tractament d’aigües residuals industrials. Els processos d’oxidació avançada (AOPs) ...
Contribution to the development of more efficient environmental policies via multi-objective optimization and environmentally extended input-output models
Al mercat globalitzat d’avui en dia la falta de coneixement sobre la distribució dels impactes entre els estats dificulta el disseny de polítiques efectives per la reducció, a escala global, de la degradació ambiental. ...
Environmental Management In Agriculture Based On Water And Climate Change Assessments: Tools For Decision Making By Life Cycle Approach
The irrigated world area has been increased dramatically from the mid of 20th century. Freshwater use and its consumption have emerged as areas of high environmental concern. Although agricultural lands represent only 12% ...
Development of electrochemical biosensors for the detection of biological warfare agents
En aquesta tesi, s’ha desenvolupat un sensitiu bio-sensor electroquímic, amb capacitat de multiplexió, simple, de baix cost i portable, per a la detecció ràpida i fiable d’agents de guerra biològica en diferents situacions ...
Supramolecular nanoarchitectures based on cyclodextrin host-guest interactions
La química supramolecular s'ha convertit en una eina molt poderosa en la construcció de noves arquitectures de mida nanomètrica amb propietats singulars. La combinació de modificacions covalents amb una àmplia gamma ...
Numerical simulation of fluid dynamics and transport phenomena in electrostatically charged volatile sprays
Els electrosprays estan constituïts de microgotes amb alta càrrega elèctrica i en moviment sota l'acció de forces electrostàtiques. Les gotes es generen com a resultat de la ruptura d'un doll de líquid sotmès a un camp ...
Bioanalytical applications of polyoxometalates using molecular tools for detection of DNA and SNPs in primer extension
L'objectiu general de la present tesi és el desenvolupament d'una plataforma per la detecció electroquímica de mutacions genètiques emprant un mètode d'alta especificitat basat en l'extensió de seqüències d'ADN, anomenades ...
Encapsulation of omega-3 fatty acids by premix membrane emulsification
In food and pharma industry, fish oils are highly demanded due to the many associated health benefits of omega-3 fatty acids. However, the delivery of fish oil through food is a major challenge as this oil is susceptible ...
Modelling, monitoring and control of reverse somsis desalination plants using data-based techniques
This thesis presents two successful applications of data-driven models developed for a reverse osmosis desalination pilot plant. The Support Vector Regression (SVR) modeling approach for steady state operation of the reverse ...
Modelling of self-organizaton of microtubules in plant cells
Microtubules are ubiquitous elements of any eucaryotic cell, serving many functions at different stages of its life. In plant cells they form so-called plant cell cortex, where they are organized into parallel arrays. These ...
Carbon molecular sieve membranes for gas separation
Membrane separations are simple, energy efficient processes, which can be economically competitive with traditional separation technologies. In the case of gas separation both dense and porous materials have been developed ...
Analysis of climate change impact on hydrological ecosystem services and water allocation in water scarce mediterranean river basins
The Mediterranean region appears to be particularly responsive to global and climate change, causing decrease in annual river flows and making the region most prone to an increase in drought hazard and water stress. This ...
Development of advanced mathematical programming methods for sustainable engineering and system biology
The main goal of this thesis is to develop advanced mathematical programming tools to address the design and planning of sustainable engineering systems and the modeling and optimization of biological systems. First we ...
Microalgae downstream processing and economical approaches of biodiesel producton processes
Microalgae oil has been identified as a reliable resource for biodiesel production due to its high lipid productivity and potential cultivation in non-fertile locations. However, high scale production of microalgae based ...
Complex network approaches to small team analysis. Conflict and gender
En un contexto donde los equipos juegan un papel cada vez más importante, es de gran importancia entender el conflicto y desarrollar herramientas de diagnóstico para evitarlo. Aquí, investigamos empíricamente si es posible ...
Sustainable production of hydrogen and chemical commodities from biodiesel waste crude glycerol and cellulose by biological and catalytic processes
El hidrógeno tiene un gran potencial como combustible limpio y "verde" del futuro. En consecuencia, en esta tesis se ha investigado el desarrollo de una producción sostenible de hidrógeno y otros productos químicos a través ...
Bacterial degradation of ethyl tert-butyl ether and study of the molecular mechanisms underlying its biodegradation
L’etil tert-butil éter (ETBE) és un compost oxigenant de combustibles utilitzat a Europa per tal de reduir la contaminació de l’aire produïda per la combustió dels carburants d’automòbils. L’ús continuat d’ETBE pot ...
Bentonite fining during different white winemaking stages: effect on the chemical and sensory properties of the wine
This thesis shows the results obtained from adding bentonite at different stages of the alcoholic fermentation in protein stability and reducing the bentonite required to reach stability. Results reflect the effect of this ...
Analysis of enhanced mixing by natural and forced convection with application to chemical reactor design
We looked for new designs to enhance mixing on catalytic chemical reactors. Two models were proposed. The first one, used forced convection as the mixing enhancer and consisted of a stack of corotating disks with the ...
Enhanced excess sludge digestion using thermal and chemical petreatments
Aquesta tesi versa sobre la problemàtica de la gestió de llots de purga generats a les depuradores urbanes. La directiva 86/278/EEC referent als llots de depuradora, regula l’ús i les propietats dels llots estabilitzats i ...
