Boiling Liquid Expanding Vapor Explosions keep occurring from time to time in process plants, storage areas and transportation by road or rail, often with severe effects. There is no doubt that a better knowledge of their ...
La hidrogenación es uno de los procesos químicos industriales más importantes. Una amplia variedad de productos químicos es obtenida mediante la hidrogenación catalítica. <br/>Uno de los procesos típicos de hidrogenación ...
Esta tesis se presenta como un conjunto de artículos (ya publicados en revistas internacionales, con la excepción del Artículo 6) precedidos por una serie de capítulos introductorios. 1. Introducción. Describe los puertos ...
Poly(alkylene dicarboxylate)s constitute a family of biodegradable polymers with increasing interest for both commodity and speciality applications. The most of these polymers can be prepared from biobased diols and ...
En la presente tesis doctoral se han realizado estudios estructurales de DNA. Estudios previos han demostrado que los coiled-coils de d(ATATATATATAT) y d(ATATATATAT) tienen unos parámetros geométricos muy diferentes. El ...
Three series of aromatic copolyesters derived from poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT) and poly(hexamethylene terephthalate) (PHT) have been synthesized by melt polycondensation in which ...
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 ...
This thesis presents, discusses and compares a set of methodologies and several appropriate combinations of them, to provide accurate estimation of process variables, either for steady-state or dynamic systems. <br/><br/>Firstly, ...
Economic growth at any expense is no longer an option. Awareness of the growing human footprint is crucial to face the problems that the impoverishment of ecosystems is causing and will cause in the future. One of the key ...
Les activitats de recerca destinades a la solució dels problemes de contaminació de les aigües estan patint un fort increment en els darrers anys. <br/><br/>Entre les indústries més contaminants, cal esmentar la tèxtil i ...
(English) An important collection of Romanesque wall paintings, detached from their original places at the beginning of the 20th century, is now preserved and exhibited in the Museu Nacional d'Art de Catalunya. To define ...
El presente trabajo se ha centrado en la síntesis, caracterización y estudio estructural de poli(alfa-alquil-beta-L-aspartato)s con grupos laterales ramificados y cíclicos.<br/><br/> Se han sintetizado los monómero: ...
La Electroforesis Capilar en Fase Micelar (MECC) es una nueva técnica de separación desarrollada a partir de la Electroforesis Capilar en Zona (CZE) y basada en principios tanto cromatográficos como electroforéticos, capaz ...
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 ...
This Thesis reports the fabrication and characterization of interfaces based on conducting polymers (CPs), which are designed with at least one dimension in the nanometric scale, for bioapplications such as scaffolds for ...
The storage of hazardous materials is a necessary part of the life cycle and operation of any process plant, which intrinsically entails certain hazards and dangers. The results of historical analysis reveal that 17% of ...
In this thesis, a series of novel organic conducting polymers have been synthesized using alternative methods based on electrochemical techniques, which have allowed to broaden the knowledge in the field of the characterization ...
DE LA TESIS<br/><br/>Es una contribución al desarrollo de un nuevo método de purificación de gas de síntesis en plantas IGCC, que posibilita un incremento de la eficiencia energética de las plantas de obtención de energía, ...
La presencia de ozono a nivel de la troposfera constituye uno de los problemas de contaminación más significativos en las grandes ciudades en el mundo. La formación de ozono troposférico es provocada principalmente, por ...
Chronic wounds including pressure, venous, arterial and diabetic neuropathic ulcers, represent a significant burden to the healthcare system. These different chronic wound types do not share origin or cause, however they ...
