Abstract:

The main objective of the thesis is to construct high-performance, reduced order, electrochemical models incorporating thermal and degradation phenomenon that can be used in advanced battery management systems. These models have been developed to be computationally simple, whilst maintaining their ability to accurately represent the major electrochemical and thermodynamical degradation mechanisms of grid-connected lithium ion batteries. The performance of these models is validated numerically by comparing their output with solutions of a more sophisticated (and computationally expensive) pseud

Abstract:

For example for battery diagnosis it is essential to understand mechanisms during discharge and because of aging to optimize cell design and operating conditions. Therefore the overall battery behavior can be modeled by combining models of relevant mechanisms like porosity, charge transfer reaction and diffusion. The aim of this contribution is to define one transmission line model for modeling several of these mechanisms. Thereby a sophisticated normalization strategy allows to eliminate ambiguity and to quantify the influence of each model parameter. The results allow a better understanding

Abstract:

The majority of power generated worldwide is from combustion of fossil fuels. The sustainability and environmental impacts of this non renewable process are severe. Alternative fuels and power generation systems are needed, however, to cope with increasing energy demands. Ammonia shows promise for use in power generation, however it is costly to produce and very few methods of using it as a fuel are developed. To address the need for alternative methods of ammonia synthesis, this research designed and tested a bioelectroch

Abstract:

<p>Selective serotonin re-uptake inhibitors (SSRIs) are a new class of antidepressants used mainly for the treatment of depression and other forms of related disorders. There are a number of side effects associated with these drugs which include loss of weight, sexual dysfunction, nervousness and nausea. A fast and reliable detection method such as biosensing for the determination of the SSRIs metabolic profile is therefore essential for the appropriate dosing of these drugs. Biosensors for the determination of the SSRIs biotransformation were prepared with cytochrome P450 (2D6) isoenzyme and

Abstract:

Dans les systèmes biologiques, les barrières tissulaires permettent le transport sélectif de molécules du sang au tissu approprié. Un exemple de barrière tissulaire est la barrière hémato-encéphalique (BHE). La BHE protège le cerveau du sang et maintient l'homéostasie du microenvironnement du cerveau, ce qui est essentiel à l'activité et à la fonction neuronale. La caractérisation de cette BHE est importante, car un dysfonctionnement de cette barrière est souvent révélateur de toxicité ou de maladie. Bien que le nombre d'articles publiés dans le domaine du développement et de la caractérisatio
