Download or read book Organic Solid State Lasers written by Sébastien Forget and published by Springer. This book was released on 2013-07-03 with total page 179 pages. 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.

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.
Download or read book Supra materials Nanoarchitectonics written by Katsuhiko Ariga and published by William Andrew. This book was released on 2016-10-07 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supra-materials Nanoarchitectonics provides the latest information on design at the nanoscale, presenting a range of the new challenges that arise as the manipulation techniques that work at the macro- and micro-scale do not work at the nanoscale. The term nanoarchitectonics, coined by Japan's National Institute for Materials Science (NIMS), describes the organized interactions required at the nanoscale, replacing the traditional structure-building approach used in materials design. Nanoarchitectonics approaches material design via a profound understanding of the interactions between individual nanostructures and their organization. As the nanoarchitectonics paradigm fits well with the discipline of supramolecular chemistry, this book brings together these two approaches to demonstrate the potential of supramolecular nanoarchitectonics in the development of new materials, both at the nano- and macro-scale. - Written by the team that coined the term nanoarchitectonics, providing a detailed explanation of the approach and techniques of supramolecular nanoarchitectonics - Demystifies materials design via organized interactions at the nanoscale - Explains this new paradigm via practical scientific techniques
