La investigació que es presenta en aquesta tesi es centra en l'aplicació i millora de metodologies analítiques existents i el desenvolupament de nous procediments que poden ser utilitzats per a l'estudi dels efectes ...
Serrano Plana, Joan (Fecha de defensa: 2016-07-26)
The oxidation of hydrocarbons is one of the most important processes in the chemical industry, and it is often related to highly toxic reagents that generate a big amount of undesired residues. In sharp contrast, oxygenase ...
Vidal Sánchez, Diego (Fecha de defensa: 2019-07-24)
The oxidation of hydrocarbons under soft and selective conditions is a reaction almost exclusively produced under these conditions by enzymes. A lot of these enzymes, posses iron in their metal center, responsible for the ...
Verkh, Yaroslav (Fecha de defensa: 2019-01-28)
Individual hazardous chemicals and substance mixtures with synergistic toxicity ef-fects occur in the dissolved organic matter (DOM) of wastewater and negatively im-pact human health. Yet a large number of chemicals and ...
Postils Ribó, Verònica (Fecha de defensa: 2018-05-07)
In this thesis, the three constituent areas of chemistry (in agreement with Jensen's quotation in his "Introduction to Computational Chemistry" book), which are construction, transformation, and properties of molecules, ...
Moret Solà, Sònia (Fecha de defensa: 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 ...
Rios Losada, Carolina (Fecha de defensa: 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 ...

High pressure processing is a food preservation technique which can be an alternative to heat treatment. Pressurization, in theory, produces changes in organoleptic properties and antioxidant compounds to a lesser extent. ...
El Bakouri El Farri, Ouissam (Fecha de defensa: 2017-11-22)
Aromaticity is a key concept in chemistry, used by chemists to explain the structure, stability, and reactivity of many compounds. Aromatic compounds are present in industrial processes as well as in living systems. ...
D'Amore, Lorenzo (Fecha de defensa: 2021-12-10)
The oxidative activation of C(sp3)–H bonds under ambient conditions represents a challenge to modern chemistry, nevertheless it is commonly operated in Nature by various oxygenases in key metabolic transformation and ...
Rodríguez Serrat, Mònica (Fecha de defensa: 2019-09-27)
In the last decades, carbenes have shown a huge potential and versatility in organometallic and organic chemistry. In each of these fields, first row transition metal chemistry is less developed than noble metal complexes. ...
Serra Parareda, Jordi (Fecha de defensa: 2018-06-21)
Most of the different homogeneous reactions catalyzed by gold have been developed in the past fifteen years and stem from the ability of both Au(I) and Au(III) complexes to coordinate and activate multiple carbon-carbon ...
Garcia Bosch, Isaac (Fecha de defensa: 2011-12-20)
Enzymes are high-weight molecules which catalyze most of the metabolic processes in living organisms. Very often, these proteins contain one or more 1st row transition metal ions in their active center (Fe, Cu, Co, Mn, Zn, ...
Ruiz-Barragán, Sergi (Fecha de defensa: 2014-09-19)
Conical Intersections (CI) are points in Potential Energy Surfaces (PES) of two or more states that have the same energy. They are fundamental to understand photo-chemical processes. These points are not isolated points, ...
Torres Antón, Òscar (Fecha de defensa: 2017-02-24)
Some of the most powerful methods for synthesizing complex organic molecules with high levels of chemo-, diastereo- and enantioselectivity rely on metal carbene chemistry. These compounds are versatile reaction intermediates ...
Vieta i Corcoy, Pep Anton (Fecha de defensa: 2017-02-07)
Throughout this thesis I was involved in different science communication projects where research and innovation have been applied to improve existing proposals and exploring new formats without forget the evaluation of the ...
Turull López, Marta (Fecha de defensa: 2019-07-19)
This thesis is focused on the use of the Diffusive Gradient in thin film (DGT) technique for the analysis of bioavailable mercury and other trace metals in water and soil. Homemade DGT devices using a selective ion-exchange ...
Clarasó Petit, Carlota (Fecha de defensa: 2019-02-08)
Metalloenzymes are a fundamental source of inspiration for synthetic chemists. Oxidation metalloenzymes catalyze oxidation reactions with high efficiency under very mild experimental conditions exhibiting exquisite regio- ...
