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 ...
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, ...
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 ...
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 ...

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 ...
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 ...
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 ...
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 ...
