Roldán Gómez, Steven (Date of defense: 2020-01-14)
During the last decades, computational chemistry has become a resourceful tool in the quest to understand and predict the mechanism and the reactivity of chemical systems. This is especially true in the area of ...
Butchosa Robles, Cristina (Date of defense: 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 ...
Calvó-Tusell, Carla (Date of defense: 2023-06-02)
Enzymes are molecules that play a crucial role in many biological and chemical processes. To understand how they work and how to design enzymes with specific functions, it is important to study their molecular structure ...
Serrano Hervás, Eila (Date of defense: 2022-07-20)
Chiral 1,2-amino alcohols are motifs widely present in different high valuable biologically active compounds. Many synthetic and enzymatic routes have been developed for producing optically active amino alcohols starting ...
María Solano, Miguel Ángel (Date of defense: 2021-02-12)
Enzymes are sophisticated biomacromolecules whose function is linked to its three-dimensional structure and conformational dynamics. Therefore, the understanding of enzyme conformational dynamics can be exploited to ...
Luque Urrutia, Jesús Antonio (Date of defense: 2021-03-26)
Given the existing problem of Climate Change, we must work towards more environmentally friendly chemical processes that would help us solve it. The thesis focuses on the study of different chemical reactions involved in ...
Castro Aguilera, Abril Carolina (Date of defense: 2017-11-17)
Nuclear Magnetic Resonance (NMR) spectroscopy is an indispensable structural tool in the modern analytical arsenal of chemists and structural biologists. The present thesis is a computational study of the NMR shift constants ...
Artigas Ruf, Albert (Date of defense: 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 ...
Corbera Mas, Marta (Date of defense: 2008-02-15)
El glifosat és un herbicida no selectiu àmpliament utilitzat en cultius agrícoles i zones no agrícoles que requereixen un control de la vegetació. Tot i la baixa toxicitat del glifosat en si mateix, la seva aplicació es ...
Moret Solà, Sònia (Date of defense: 2006-12-15)
El control d'herbicides i altres anàlits orgànics presents en el medi ambient constitueix una pràctica habitual en els laboratoris des de l'establiment de legislacions que limiten la seva concentració. Per aquesta raó, cal ...
Sirvent Masias, Gemma (Date of defense: 2005-04-22)
El desenvolupament de mètodes d'anàlisi de compostos fenòlics és una pràctica habitual en molts laboratoris des de l'establiment de mesures legislatives de control de les concentracions d'aquestes substàncies en el medi ...
Rios Losada, Carolina (Date of defense: 2004-04-16)
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. ...
