En los últimos años, los contaminantes emergentes (ECs) están recibiendo una creciente atención debido a los efectos nocivos que suponen para los organismos vivos y al riesgo ambiental que representan. Existen una gran ...
Alagia, Adele (Date of defense: 2015-12-11)
To direct post-transcriptionally gene silencing, RNAi machinery exploits the formation of base pairs between the loaded guide strand and the complementary mRNA. The Ago2 protein is the “slicer” effector of the RISC and ...
Matencio Lloberas, Sonia (Date of defense: 2015-10-29)
Organic/inorganic interfaces play a key role in organic electronic devices such as organic light emitting diodes (OLED), organic field effect transistors (OFET) and organic solar cells (OSC). In these interfaces crucial ...
Barón González, Enrique (Date of defense: 2015-11-16)
Los retardantes de llama halogenados (HFRs) se aplican a una gran variedad de materiales, como muebles, textiles, material electrónico, etc., con el objetivo de prevenir los incendios. La demanda global se incrementa año ...
Boleda Vall-llovera, Mª Rosa (Date of defense: 2015-11-23)
Les drogues d'abús i els fàrmacs estan considerats com contaminants d'interès emergent en el medi aquàtic, és a dir, són substàncies que no estan incloses en els programes habituals de control i monitorització d'aigües, ...
Bolívar i Subirats, Gabino (Date of defense: 2015-11-05)
Els plastificants són additius o monòmers dels plàstics que s'empren durant la fabricació d'aquests per modificar propietats fisicoquímiques. Poden arribar al medi ambient a partir de focus industrials, ja que són produïts ...
Atcher Ubiergo, Joan (Date of defense: 2015-07-28)
Dynamic combinatorial chemistry proposes the creation of a library of compounds (dynamic combinatorial library, DCL) inter-connected through reversible chemical processes. The concentrations in a DCL are determined by ...
Lendínez Gris, Mª Carmen (Date of defense: 2015-06-08)
Las emulsiones son dispersiones de dos líquidos inmiscibles que, generalmente están estabilizadas por moléculas tensioactivas. Cuando la fracción en volumen de fase dispersa es superior o igual a 0,74 (valor que corresponde ...
Zhang, Xin (Date of defense: 2015-07-07)
This Thesis deals with the resolution of hyperspectral imaging data by using chemometric methods, in particular by using appropriate data pretreatment methods and by using Multivariate Curve Resolution (MCR) methods. The ...
Miras Hernández, Jonatan (Date of defense: 2015-04-16)
El principal objetivo de la presente tesis es la obtención de espumas de quitosano mediante la utilización de emulsiones altamente concentradas de tipo aceite en agua (O/W). Para alcanzar dicho objetivo, este trabajo ha ...
Sánchez Martínez, Melchor (Date of defense: 2014-12-09)
Proteins are flexible entities, and thus move. Its function is closely related to the flexibility. To carry out any function is necessary a conformational change. As protein motions imply an exchange of conformations, ...
Portell Bueso, Anna (Date of defense: 2014-11-17)
This thesis is a multidisciplinary study of the solid state of squaric acid derivatives which combines approaches from areas such as crystal engineering, supramolecular chemistry and crystallography. The structural preferences ...
Pereira de Magalhaes e Couto, Miguel (Date of defense: 2014-11-10)
The main subject of this Thesis is the production of hard, wear and corrosion resistant cermets tungsten carbide and cobalt cermets (WC-Co) with different contents in cobalt matrix, onto low carbon steels and aluminum alloy ...
Vílchez Maldonado, Silvia (Date of defense: 2014-03-21)
El objetivo principal de la presente tesis es el diseño de nanopartículas de etilcelulosa para su utilización como vehículos de principios activos o sustancias lipofílicas y su deposición sobre un tejido, con la finalidad ...
Serra Vidal, Bernat (Date of defense: 2014-05-27)
Alzheimer’s disease (AD) is a neurodegenerative disorder which major risk factor is age. Current drugs only offer symptomatic alleviation in AD, thus a disease-modifying treatment is urgent. The amyloid-β (Aβ) protein ...
Miret Casals, Laia (Date of defense: 2014-05-23)
CHAPTER 1: Respiratory Infectious Diseases (RID) are diseases affecting the air passages, the bronchi and the lungs. They range from acute infections, such as pneumonia and bronchitis, to chronic conditions such as ...
Martínez Rodríguez, María (Date of defense: 2014-07-10)
El objetivo principal de la presente tesis ha sido la preparación y caracterización de emulsiones bituminosas concentradas y altamente concentradas de betún en agua controlando el tamaño de gota. Las investigaciones y ...
Mendieta Martínez, Laura (Date of defense: 2014-06-06)
Proteases are involved in a high number of diseases, and thus, are relevant targets. For that reason our main goal was the discovery of protease inhibitors as therapeutic agents. We focused our study in four proteases: ...
Postma, Tobias Maria (Date of defense: 2014-03-21)
Cysteine (Cys) is a unique amino acid due to its ability to form reversible covalent disulfide bonds. These bonds cause conformational constraints which make peptides or proteins more rigid and stable. In addition, the ...
Guixer, Bernat (Date of defense: 2014-03-31)
The blood-brain barrier (888) is a biological barrier that plays a crucial role protecting the brain from neurotoxic agents and regulating the influx and efflux of molecules required for the correct function of this organ. ...
