This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Depuis plusieurs années, les lampes à excimères font l'objet de nombreuses recherches. La génération du rayonnement UV et VUV contrôlée par une décharge à barrières diélectriques (DBD) par l'excitation d'un gaz rare ou d'un gaz rare halogène représente un concept prometteur pour d'autre type de source de lumière. Cette recherche se divise en deux parties, une partie expérimentale qui caractérise le plasma à pression en dessous de 150 Torr, et une partie numérique qui caractérise le plasma à une pression au-dessus de 400 Torr. La partie expérimentale concerne la caractérisation optique et électrique d'une décharge à barrière diélectrique. Le banc expérimental se repose essentiellement sur une excitation impulsionnelle, un réacteur et la présence de gaz rare. L'objectif de cette partie est d'établir un bilan général de notre lampe pour essayer de l'optimiser, et de déterminer les éléments qui influencent le dépôt de la puissance moyenne et les différents résultats de l'efficacité. La partie numérique concerne l'utilisation d'un modèle cinétique électrique pour une description homogène d'une décharge à barrières diélectriques, le modèle de la décharge se base sur un couplage de trois éléments à savoir : la cinétique réactionnelle, l'équation de Boltzmann et le circuit d'excitation. Le principal objectif de cette partie du travail est d'optimiser le dépôt d'énergie, ainsi que l'efficacité lumineuse de notre source DBD, produite par différents formes d'excitation sinusoïdale, impulsionnelle et burst. Finalement, l'optimisation du dépôt d'énergie dans les DBDs implique une meilleure compréhension des phénomènes physiques dans le plasma et des mécanismes cinétiques essentiels conduisant à la formation ou à la disparition des excimères. Les phénomènes électriques liés aux interactions entre le circuit d'excitation et la décharge affectent eux aussi d'une manière significatrice l'énergie déposée dans le milieu plasma. Ces phénomènes sont expliqués tout au long de ce manuscrit

This book was released on 2011 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Actuellement, les Ultraviolets (UV) trouvent de nos jours de nombreuses applications dans l'industrie (séchage des encres, traitements de surfaces, lithographie pour les semi-conducteurs etc...) et ils sont généralement produits par des décharges dans des vapeurs de mercure. De nouvelles sources sont cependant en plein développement : il s'agit de sources basées sur l'émission de molécules excitées par une décharge à barrière diélectrique. Plus efficaces que les sources à mercure, elles permettent une émission très localisée dans le spectre, centrée autour d'une longueur d'onde dépendant du gaz (ou du mélange de gaz) dans lequel se produit la décharge. Pour atteindre nos objectifs, nous avons tout d'abord développé une modèle physique destinée à une DBD excilampe pour un mélange entre xénon et chlore. Ce modèle repose sur la résolution du système d'équation formé principalement par les équations de continuité des espèces considérées, et l'équation de Poisson. La résolution de ce modèle nous permet de décrire la distribution spatiale et temporelle de toutes les espèces considérées dans le volume de décharge. Par la suite, grâce au modèle développé, nous avons réalisé une étude de l'influence de trois modes d'alimentations différentes (source de tension sinusoïdale et impulsionnelle, source de courant impulsionnel) sur la production d'UV par l'excilampe xénon/chlore. Ces résultats obtenus ont été confrontés avec des résultats expérimentaux issus de la littérature scientifique. Enfin, grâce à une plateforme d'étude de ces décharges développées au Laplace (système de pompage du gaz ou du mélange de gaz, bans de fabrication de lampes, outils de diagnostic et alimentations électriques), nous avons effectué, grâce à des techniques d'imagerie rapide sur la décharge étudiée, des mesures spectrales résolues en temps. Ces mesures nous ont permis d'évaluer la performance de différents modes d'alimentation à la fois sur l'efficacité de production UV de la décharge et également sur la durée de vie. Sur les bases des résultats obtenus dans cette partie, nous pouvons choisir une meilleure alimentation pour une excilampe xénon/chlore

Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
