This book was released on 2002 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: La spectroscopie d'absorption infrarouge par diode laser accordable permet d'allier sensibilité, sélectivité et résolution temporelle élevées. Nous avons appliqué cette technique à la mesure de polluants atmosphériques en traces et à la cinétique de réactions élémentaires en phase gazeuse. En métrologie, nous avons développé un protocole original et performant : mesure par augmentation de pression. Il a été appliqué à la mesure en protoxyde d'azote, en formaldéhyde, en acétaldéhyde et en 1,3-butadiène, dans l'air ou les gaz d'échappement automobile. Ce travail représente un premier pas vers l'élaboration d'un instrument de terrain compact et transportable. Le dispositif de cinétique, où les réactions sont initiés par photolyse laser, a été validé par l'étude des réactions des radicaux formyle et hydroxyméthyle avec l'oxygène. Une étude préliminaire de la constante de décomposition unimoléculaire du radical pivaloyle a été effectuée.

Download or read book Quantum Mechanics Volume 3 written by Claude Cohen-Tannoudji and published by John Wiley & Sons. This book was released on 2019-12-16 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
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 Air Pollution Studies written by G Passerini and published by WIT Press. This book was released on 2020-05-18 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air pollution issues remain one of the most challenging problems facing society. This wide-ranging collection of high-quality works contains valuable research on issues related to the modelling, monitoring and management of air pollution. The papers included in this book develop the fundamental science of air pollution. Scientific knowledge derived from well-designed studies needs to be allied with further technical and economic studies in order to ensure cost-effective and efficient mitigation. Increasingly, it is being recognised that the outcome of such research needs to be contextualised within well-formulated communication strategies that help policymakers and citizens to understand and appreciate the risks and rewards arising from air pollution management. Details of the widespread nature of the air pollution phenomena and in-depth explorations of their impacts on human health and the environment are covered in this book.
Download or read book Laser 50 Years Of Discoveries written by Fabien Bretenaker and published by World Scientific. This book was released on 2014-10-27 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book provides an overview of the principle and applications of lasers enriched with numerous illustrations.Being over fifty years old, lasers continue to amaze us. Their performance characteristics are constantly reaching new limits, and the scope of their applications continues to expand. Yet, it took years of effort by teams of physicists to transform the fundamental notions of Einstein into the first experimental beam of laser light. And history is still going on as fundamental research is now triggered by its remarkable properties.This book addresses every aspects of laser light, from its fundamental principles to its industrial applications, at a level particularly suited for high school teachers, students, and anybody curious about science and technology.
Download or read book Fine Line Lithography written by R Newman and published by Elsevier. This book was released on 2012-12-02 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials Processing - Theory and Practices, Volume 1: Fine Line Lithography reviews technical information as well as the theory and practices of materials processing. It looks at very large scale integration (VLSI) technology, with emphasis on the creation of fine line patterned structures that make up the devices and interconnects of complex functional circuits. It also describes a variety of other technologies that provide finer patterns, from modified versions of optical methods to electron-optic systems, non-plus-ultra of X-ray techniques, and dry processing that uses the chemical or kinetic energies of gas molecules or ions. Organized into five chapters, this volume begins with an overview of the fundamentals of electron and X-ray lithography, with a focus on resists and the way they function, and how they are used in microfabrication. It then discusses electron scattering and its effects on resist exposure and development, electron-beam lithography equipment, X-ray lithography, and optical methods for fine line lithography. It systematically introduces the reader to electron-beam projection techniques, dry processing methods, and application of electron-beam technology to large-scale integrated circuits. Other chapters focus on contact and proximity printing, projection printing, deep-UV lithography, and shadow printing with electrons and ions. The book describes reactive plasma etching and ion beam etching before concluding with a look at factors affecting the performance of the scanning-probe type of systems. This book is a valuable resource for materials engineers and processing engineers, as well as those in the academics and industry.
