Feixas Geronès, Ferran (Data de defensa: 2011-02-04)
Interactions between electrons determine the structure and properties of matter from molecules to solids. Therefore, the understanding of the electronic structure of molecules will enable us to extract relevant chemical ...
Serrat i Sitjas, Xavier (Data de defensa: 1999-06-04)
L'objectiu principal de la present tesi doctoral ha consistit fonamentalment en la síntesi de noves heteroarilglicines òpticament pures. Amb aquesta idea s'han desenvolupat dues estratègies diferents: síntesi estereoselectiva ...
Heras i Corominas, Montserrat (Data de defensa: 1999-07-27)
According to a strategy based on an Aza-Wittig reaction type, an efficient methodology in solution toward the synthesis of libraries of 2-aminoimidazolones with high molecular diversity has been developed. The strategy is ...
Cabarrocas Duran, Gemma (Data de defensa: 1999-12-17)
El treball experimental que ha permès redactar la present Tesi Doctoral ha estat dividit en dues parts. A la primera part es presenten els resultats referents a la síntesi estereocontrolada de noves heteroarilglicines ...
Ribas Agustí, Albert (Data de defensa: 2013-05-31)
The doctoral thesis has developed new methods for the analysis of phenolic compounds in tomato, lettuce and dry-cured sausages with vegetable extracts. The new-developed chromatographic methods are simplified and validated, ...
Vilajeliu Pons, Anna (Data de defensa: 2017-05-26)
The doctoral thesis has focused on the simultaneous removal of carbon and nitrogen in BES for future application in the treatment of industrial wastewater as swine manure. The bacteria that use the electrode as electron ...
Butchosa Robles, Cristina (Data de defensa: 2012-06-22)
The present thesis models nucleobase-amino acid charge transfer reactions, which can serve as base for future computational investigations of charge transfer processes in DNA-protein systems. Guanine and adenine charge ...
Escoda i Acero, Ma. Lluïsa (Data de defensa: 2000-07-14)
Due to the large quantity of contamination by Fe in the waterlogged wood and the composites previously processed with poliethilenglycol, PEG , we have thought the possible extraction and formation of complexes Fe-L (L= ...
Artigas Ruf, Albert (Data de defensa: 2020-01-31)
Fullerenes are a group of spherical molecules with outstanding 2/1 physicochemical properties that make them important materials in a variety of fields, ranging from biomedicine to photovoltaics. However, in order ...

Aquesta tesi doctoral està basada en el desenvolupament de nous agents antimicrobians derivats del pèptid híbrid cecropina A-melitina WKLFKKILKVL-NH2 (Pep3) que siguin sostenibles i útils per al control de malalties de ...
Ponzelli, Michele (Data de defensa: 2023-12-11)
Freshwater scarcity is a growing concern, prompting the exploration of water reuse strategies. Anaerobic wastewater treatment is gaining popularity due to its low energy requirements and the potential for resource recovery. ...
Valls Cantenys, Carme (Data de defensa: 2014-11-21)
The presence of anthropogenic chemical substances in water resources can affect the ecological balance of aquatic systems, as well as human health, and therefore it is necessary to control their presence in water bodies. ...
Álvarez Yebra, Rubén (Data de defensa: 2023-11-07)
Cavitands are macromolecules with a permanent cavity where smaller molecules or ions can be accommodated. The hydrophobic cavity of these supramolecules allows the binding of other molecules though non-covalent interactions, ...
Vilà Roura, Sílvia (Data de defensa: 2014-07-28)
Les malalties causades per bacteris i fongs són responsables d’importants pèrdues econòmiques en cultius. Es considera que els pèptids antimicrobians, naturals i sintètics, són uns bons candidats per a ser utilitzats com ...
