Integration of nanofiltration and diffusion dialysis for the sustainable management of acidic liquid wastes
Nowadays mining and hydrometallurgical industries generate a considerable amount of acidic liquid wastes (ALWs), which are characterised by a low pH and the presence of metals (e.g. Fe, Cu, Zn and Rare Earth Elements (REEs) ...
Avaluació d'alternatives industrials per a l'obtenció de nous materials que valoritzen residus queratínics
The worldwide poultry industry generates a large amount of wastes which, accordingly to the current law, are mostly discarded. These wastes include chicken feathers, keratin structures which 109.056.179 ton were generated ...
Smart hybrid nanomaterials for biomimetic membranes
This thesis focuses on the preparation of nanomaterials made of proteins and polymers. Even though the technology has advanced in the last decades to design new devices at the atomic scale, researchers are still inspired ...
Multifunctional enzymatically-generated hydrogel platforms for chronic wound application
Chronic wounds became burdensome problem of worldwide healthcare systems, along with the increased elderly population, which is the most vulnerable risk group, predisposed to their development. Chronic wounds represent a ...
Hybrid block and graft copolymers made from macrolactones and α-amino acids for applications as drug delivery nanosystems
Naturally produced peptides or proteins can be regarded as highly refined polymers. When synthetic polymers are married to proteins or peptides, the resulting bioconjugates can synergistically combine the properties of the ...
Nanoestructuras de TiO2 de baja dimensionalidad para la obtención fotocatalítica de hidrógeno
Hydrogen is one of the most promising solutions for the energy future, since its combustion only produces water vapour, so it does not pollute. In addition, it can be obtained from abundant and renewable substances. Fuel ...
Conceptual modelling for integrated decision-making in process systems
This Thesis addresses the systematic construction of Decision Making Models (DMMs) from the conceptualization stage to its application in specific situations, with special emphasis on !he treatment of scenarios where there ...
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 ...
