This work is focused on the production and characterization of: (1) Fe based nanocrystalline soft magnetic materials of NANOPERM and HITPERM families and (2) Heusler magnetic shape memory alloys. Within the first typology, ...
In order to evaluate the increasing environmental and human risk of anticancer drugs in the environment, more information needs to be gathered about their presence, their toxicity, bioaccumulation and persistence. In ...
This thesis presents different studies on hydrogen bonds that occur between two molecules. It is because of the biological importance of DNA that the base pairs, and other compounds with similar hydrogen bonds as these ...
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 ...
En este trabajo se ha estudiado el potencial tanto los filamentos de cáñamo como de la cañamiza como refuerzo/carga del polipropileno. La modificación de estos materiales se realiza para lograr una mayor compatibilidad con ...
The combination of two membrane technologies coupled together in series has become a standard technology when it comes to producing reclaimed water of high quality for potable reclamation or industrial applications. This ...
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 ...
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 ...
Fire blight is a disease caused by Erwinia amylovora. For the limited effectiveness of copper products and the new regulations for the sustainable use of pesticides, biological control is considered a good alternative for ...
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 ...
The food safety challenges derived from the market demands towards convenient food, such as ready-to-eat meat products with extended durability, motivate food business operators to explore and adopt new intervention ...
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, ...
Density functional theory (DFT) was postulated almost 60 years ago and equipped chemists with a powerful framework to simulate, in silico, the behavior of chemical systems. Despite its widespread utility, DFT methods have ...
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 ...
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 ...
The work presented in this PhD thesis includes various partial studies aimed at developing a decision support system for membrane bioreactor integrated control. The decision support systems (DSS) have as a main goal to ...
Un pont de dihidrogen (dihydrogen bond,DHB) és un tipus de pont d'hidrogen atípic que s'estableix entre un hidrur metàl·lic i un donador de protons com un grup OH o NH. Els ponts de dihidrogen són claus en les característiques ...
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. ...
The biological treatment of industrial wastewater containing high nitrogen concentrations (>1000 mg N L-1) and low biodegradable organic matter (bCOD) such as landfill leachate is nowadays challenging. Conventional ...
Water stands out as the most essential resource currently under serious threat. The combination of water scarcity and increasing pollution of available water poses significant challenges to governance and society. Typically, ...
