Book excerpt: L'exploitation de méthodes théoriques dans le cadre de la modélisation de propriétés moléculaires remarquables s'est substantiellement développée lors des dernières décennies, notamment grâce au progrès des technologies informatiques qui rendent désormais accessibles certaines informations cruciales à nos recherches grâce au calcul intensif. Il est maintenant possible d'évaluer des propriétés et de résoudre des problèmes théoriques de haut niveau grâce aux ressources calculatoires actuelles. Dans ce cadre, la caractérisation par la mécanique quantique des états excités moléculaires constitue toujours un défi d'une très grande richesse suscitant un intérêt accru de la communauté de physique moléculaire théorique et expérimentale. Cette qualité s'accompagne d'une grande complexité d'étude, conséquence du nombre de phénomènes physiques caractérisant l'accès d'un système à ses états excités. Notre contribution s'inscrit dans ce contexte, puisque les études dont ce document fait état sont relatives à la rationalisation du comportement de chromophores face à la capture d'un photon. Cette interaction entre la lumière et la matière est rapportée à l'échelle moléculaire et décrite dans nos travaux par des méthodes quantiques en vue de comprendre les mécanismes inhérents aux propriétés caractéristiques de composés-cibles. Ces interprétations sont appuyées par des développements théoriques visant l'établissement ou la consolidation des outils conceptuels et mathématiques constitutifs de nos stratégies théoriques d'investigation des états excités. Les développements qui font l'objet de ce document portent principalement sur l'interaction des chromophores avec leur vicinité moléculaire traitée implicitement ou explicitement dans le cadre d'une résolution géométrique du spectre d'absorption électronique, ainsi que sur une approche quantitative de la réorganisation de la structure électronique d'un composé induite par l'absorption d'un photon. Les applications sont quant à elles relatives à des chromophores présentant des propriétés remarquables : sonde solvatochromique, sonde à explosifs, chromophore interagissant avec l'ADN, composés intervenant dans la constitution de cellules solaires de troisième génération, clusters multichromophores.

Available in PDF, EPUB and Kindle. Book excerpt: Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.

Available in PDF, EPUB and Kindle. Book excerpt: Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.

This versatile material class can be used in nanocomposites such as rubber or polyester, and in functional materials such as drug carriers, bio-inspired mechanically adaptive materials or membranes. Moreover, polysaccharide-based nanomaterials are environmentally friendly due to their intrinsic biodegradability. With its interdisciplinary approach the book gives a thorough introduction to extraction, structure, properties, surface modification, theory, and mechanisms of material formation of polysaccharide nanocrystals from renewable resources. In addition, it provides an in-depth description of plastics, composites, and nanomaterials from cellulose nanocrystals, chitin nanowhiskers and starch nanocrystals. The first focused, concise and coherent treatment of nanomaterials made from renewable resources such as cellulose, chitin, and starch - for scientists, engineers, graduate students and industrial researchers in the field of polymeric materials.

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.
