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.

Book excerpt: This third volume in the series represents the Proceedings of the 3rd International Nanophotonics Symposium, July 6-8, 2006, Icho-Kaikan, Osaka University, Osaka, Japan. Over a two-day symposium, distinguished scientists from around the world convened to discuss the latest progress in this field and the conclusions have been summarised in Nano Biophotonics: Science and Technology. The contents of this book have been compiled by invited lecturers, research members of the relevant projects/program, and some of general participants. The book has 27 chapters which are classified into 4 parts; nano bio-spectroscopy, nano bio-dynamics, nano bio-processing, and nano bio-devices.* Bridges the gap between conventional photophysics & photochemistry and nanoscience* Continuing the series that focuses on 'hot' areas of photochemistry, optics, material science and bioscience

Available in PDF, EPUB and Kindle. Book excerpt: Mathematical methods play a significant role in the rapidly growing field of nonlinear optical materials. This volume discusses a number of successful or promising contributions. The overall theme of this volume is twofold: (1) the challenges faced in computing and optimizing nonlinear optical material properties; and (2) the exploitation of these properties in important areas of application. These include the design of optical amplifiers and lasers, as well as novel optical switches. Research topics in this volume include how to exploit the magnetooptic effect, how to work with the nonlinear optical response of materials, how to predict laser-induced breakdown in efficient optical devices, and how to handle electron cloud distortion in femtosecond processes.

This book was released on 2003 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de la thèse est d'étudier des dispositifs électrochromes sur support flexible. Ces systèmes ont une transmission dans le visible et le proche infra-rouge qui peut être modulée sous l'effet d'une tension électrique. Ils sont constitués d'un empilement de couches minces : - un film électrochrome à coloration cathodique à base de WO3, - une couche conductrice ionique au lithium, inorganique (LiPON) ou organique gélifiée, - une contre-électrode à coloration anodique (''LixNi0.5O'') ou optiquement passive (V2O5). Cet ensemble, compris entre deux électrodes conductrices transparentes est déposé sur PET. Les couches électrochromes et l'électrolyte inorganique sont déposés par pulvérisation cathodique. La corrélation entre paramètres de dépôt, propriétés électrochromes et propriétés structurales a été établie.
