El glifosat, N-(fosfonometil) glicina, és un dels herbicides més utilitzats arreu del món a causa de la seva baixa toxicitat i al seu ampli espectre d'aplicació. A conseqüència del gran ús que se'n fa, és necessari ...
Luis Luis, Josep Maria (Date of defense: 1999-06-28)
The vibrational contribution to nonlinear optics (NLO) properties is the mean goal of study of this Thesis. The vibrational contribution can be split in the nuclear relaxation contribution and the curvature contribution. ...
Ferre Malagon, Rafael (Date of defense: 2010-07-23)
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 ...
Vera Chamorro, Ruben (Date of defense: 2019-03-15)
Water is essential for humankind not only for its direct consumption but also for its multiple applications in industry or agriculture, among others. The presence of undesirable substances or pollutants directly affects ...
Insa Aguilar, Sara (Date of defense: 2006-05-22)
D'entre els defectes organolèptics associats al vi, en destaca l'anomenat "gust de suro" habitualment vinculat a la presència de cloroanisoles, els quals són productes de l'activitat microbiana formats a partir dels ...
Gimferrer Andrés, Martí (Date of defense: 2023-03-27)
In the last decades, electronic structure methods have been crucial for chemists to achieve deeper insight into chemistry itself and to make predictions before performing the actual experiments. The development of computational ...
Godayol Boix, Anna (Date of defense: 2014-03-27)
Different analytical methodologies have been developed for the determination of odorous compounds and synthetic fragrances in water and air WWTP samples from Girona and Tarragona provinces. With regards to the odorous ...
Valls Cantenys, Carme (Date of defense: 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. ...
Güell Martí, Raquel (Date of defense: 2011-10-07)
The chemical contamination of natural waters is a global problem with a worldwide impact. Considering the relevance of this problem, this thesis is intended, on one hand, to develop different separation/preconcentration ...
Álvarez Yebra, Rubén (Date of defense: 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, ...
Ferrer Vall-llosada, Íngrid (Date of defense: 2015-07-16)
In this thesis we present the synthesis and characterization of different types of ruthenium complexes containing N-donor ligands together with dmso, Cl and H2O ligands, along with their complete characterization through ...
Alonso Roura, Mònica (Date of defense: 2012-12-14)
Hippocrates predicted many years ago that breath could tell something related with our health. On his treaties, he indicated that when the body starts moving after sleeping, and breathe with more frequency, something hot ...
