Study of conductive polymers, biomolecules and their hybrids through computational approaches
In this thesis, different theoretical approaches designed to study a wide interval of length- and/or time-scales have been used to examine the microscopic properties of chemical systems with varying degrees of complexity ...
Design and analysis of dual-curing systems
Dual-curing processing is a method to prepare thermoset materials through two polymerization reactions carried out simultaneously or sequentially. In these processes, a firm understanding of reaction mechanisms enables ...
Ionic complexes of naturally-occurring biopolymers and cationic surfactants : a platform for industrial and biomedical applications
In recent years, the increasing public concern about the environmental pollution caused by persistent plastic wastes has stimulated the interest in replacing synthetic polymers by biopolymers. The term biopolymer refers ...
Inverse modelling in wildfire spread forecasting: towards a data-driven system
Wildfires are an ecological phenomenon inherent to earth dynamics and widely spread over the globe. In addition to the environmental impact, when wildfires grow beyond controllable magnitudes, they pose a principal threat ...
A contribution to support decision making in energy/water sypply chain optimisation
The seeking of process sustainability forces enterprises to change their operations. Additionally, the industrial globalization implies a very dynamic market that, among other issues, promotes the enterprises competition. ...
Enhancing the thermal efficiency of a salinity gradient solar pond. Implementation of the study in the design, construction, salinity gradient establishment, operation and energy transfer at industrial scale
The energy model in the last decades has been dominated by the consumption of fossil fuels assuming a high environmental cost. Global warming and the destruction of the ozone layer are two examples of the deterioration ...
Towards the wastewater treatment plant of the future : integration of carbon redirection and nitrogen recovery technologies
Most of the urban wastewater treatment plants (WWTP), based on conventional activated sludge (CAS) systems, cannot be considered sustainable since the concept of resources (energy and nutrients) recovery is not taken into ...
Nutrient recovery from waste water treatment plant by sorption processes : technical and economic analysis
In the last years has been performed a huge number of research related to nutrients (mainly N and P) recovery from waste water in order to promote their reuse and also to avoid eutrophication. Recovering nutrient from waste ...
The role of superplasticizers and their degradation products on radionuclide mobility
The most widely accepted option for the long-term management of radioactive waste materials considers their disposal in deep underground facilities (examples are Finland, Belgium, France, Sweden, etc.). Such installations ...
Data driven methods for updating fault detection and diagnosis system in chemical processes
Modern industrial processes are becoming more complex, and consequently monitoring them has become a challenging task. Fault Detection and Diagnosis (FDD) as a key element of process monitoring, needs to be investigated ...
Characterization of amino acid changes in visual pigment evolution and interaction with associated proteins
Visual opsins are G protein-coupled receptors that function as light photoreceptors in the vertebrate retina. Rhodopsin is the visual pigment located in the rod photoreceptor cells specialized in scotopic vision. Bovine ...
Application of computer simulation approaches to study the structure and properties of polymeric systems
The study at the nanoscopic level of the polymeric systems is a keystone for a deeper understanding of their internal structure and properties, not only at nanometric scale but also at macroscopic level. The disciplines ...
Developmet of flexible electrodes and lightweight capacitors
This work has focused on the study and development of hierarchically, flexible electrodes and lightweight capacitor using as a source of flexibility. the y-polyglutamic acid (y-PGA) and as an electroactive polymer the ...
Polyesters containing cyclic carbohydrate-based units obtained by ring opening polymerization
In recent years, as a result of climate change, the interest in sustainable materials has increased dramatically. The replacement of compounds of petrochemical origin by bio-based has spread to all areas of chemistry. ...
Self-assembly of phenylalanine derivatives
Since the pioneering work of Reches and Gazit in 2003, in which the formation of diphenylalanine (FF) nanotubes in aqueous solution was discovered, significant efforts have been made to develop a new generation of biomaterials ...
Sustainable plastics derived from renewable resources
In this century, the major use of synthetic polymers have been as replacements for more traditional materials, particulary in packaging. Today the packaging industry is by far the major user of plastics. Another interesting ...
Contribución al análisis de riesgos en el transporte de materiales peligrosos por tubería
The highly complex and interconnected today's societies require a continuous flow of materials and energy from one geographical area to another. In particular, huge amounts of often-hazardous materials, mainly liquids or ...
Contribución al desarrollo de factores de configuración de bolas de fuego con presencia de obstáculos
Fire is the most common phenomenon that characterizes major accidents that take place in both industrial establishments and in the transport of dangerous goods by road and rail. The formation of a fireball, with or without ...
Estudio de mejora de las propiedades de polímeros conductores electrogenerados : verificación de parámetros de aplicación tecnológica
Since their discovery, the spectacular properties of polymers called "conducting" have given rise to an important field of study in order to obtain knowledge about them and their commercial application in many fields such ...
Structural and functional studies of AT-Rich DNA ligands and their effect on trypanosoma brucei
AT-rich sequences confer unique properties to DNA, such as high polymorphism and flexibility. The abundance of AT-rich DNA in several pathogens' genomes and the ability of specific molecules to selectively target AT base ...
