Book excerpt: One of the most important features of the technical progress of this century has been deep and wide penetration of polymeric materials into all fields of human life. But, more than a half century of their use has revealed some shortcomings common to all of these materials. Probably the most important of these is the tendency of most synthetic polymers to degradation. Polymer degradation is, in fact, a series of chemical and physical transformations occurring in the polymer during service, processing or storage, which causes deterioration in valuable properties. Many factors are responsible for polymer degradation, including heat, UV radiation, biological agents and many others. These factors, either separately or together, cause complex processes including cracking, depolymerisation, cross-linking, oxidation, etc. They may cause considerable and often quite rapid deterioration of polymer properties leading to a sharp decrease in their useful life. This volume is organised to provide a wide coverage of new and traditional polymers and their behaviour during degradation, as well as the important chemical and engineering aspects of these materials relative to processing and performance in various applications.

Book excerpt: This book deals with the Laser-Induced Breakdown Spectroscopy (LIBS) a widely used atomic emission spectroscopy technique for elemental analysis of materials. It is based on the use of a high-power, short pulse laser excitation. The book is divided into two main sections: the first one concerning theoretical aspects of the technique, the second one describing the state of the art in applications of the technique in different scientific/technological areas. Numerous examples of state of the art applications provide the readers an almost complete scenario of the LIBS technique. The LIBS theoretical aspects are reviewed. The book helps the readers who are less familiar with the technique to understand the basic principles. Numerous examples of state of the art applications give an almost complete scenario of the LIBS technique potentiality. These examples of applications may have a strong impact on future industrial utilization. The authors made important contributions to the development of this field.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive source of the fundamentals, process parameters, instrumental components and applications of laser-induced breakdown spectroscopy (LIBS). The effect of multiple pulses on material ablation, plasma dynamics and plasma emission is presented. A heuristic plasma modeling allows to simulate complex experimental plasma spectra. These methods and findings form the basis for a variety of applications to perform quantitative multi-element analysis with LIBS. These application potentials of LIBS have really boosted in the last years ranging from bulk analysis of metallic alloys and non-conducting materials, via spatially resolved analysis and depth profiling covering measuring objects in all physical states: gaseous, liquid and solid. Dedicated chapters present LIBS investigations for these tasks with special emphasis on the methodical and instrumental concepts as well as the optimization strategies for a quantitative analysis. Requirements, concepts, design and characteristic features of LIBS instruments are described covering laboratory systems, inspections systems for in-line process control, mobile systems and remote systems. State-of-the-art industrial applications of LIBS systems are presented demonstrating the benefits of inline process control for improved process guiding and quality assurance purposes.

Book excerpt: L’analyse élémentaire a connu des développements instrumentaux majeurs depuis les années 70. C’est tout particulièrement le cas avec la spectrométrie d’émission atomique à source plasma (ICP-OES), commercialisée pour la première fois en 1974, et qui s’est rapidement imposée en se déployant très largement dans les laboratoires de caractérisation. Bien que l’ICP-OES soit devenue une technique d’analyse de routine, les exigences de la mesure imposent une maîtrise complète du processus opératoire et du système de management de la qualité associé. L’objectif de cet ouvrage est de guider l’analyste durant tout le processus de validation de sa mesure et de l’aider à garantir la maîtrise de ses principales étapes : gestion administrative et physique des échantillons au laboratoire ; préparation et traitement de ceux-ci avant mesure ; qualification et suivi de l’appareillage ; réglages instrumentaux et stratégie d’étalonnage ; exploitation des résultats en termes de justesse, fidélité, incertitude et exactitude (avec la détermination pratique du « profil d’exactitude »). Le guide s’appuie pour cela sur la terminologie la plus actuelle et sur de nombreux exemples et illustrations destinés à faciliter la compréhension et la constitution des dossiers de validation de méthode. Cet ouvrage collectif a été constitué dans le cadre des travaux de la Commission d’ÉTAblissement des Méthodes d’Analyses du Commissariat à l’Énergie Atomique et aux Énergies Alternatives. Trente-huit spécialistes de l’ICP-OES, travaillant dans des laboratoires de recherches de grands organismes (AREVA, ARKEMA, CEA, C2RMF, EDF, EURODIF, IRSN) et d’Universités (Université de Pau et des Pays de l’Adour, Université Claude Bernard Lyon 1), y ont contribué durant plus de dix ans.

Available in PDF, EPUB and Kindle. Book excerpt: Laser spectroscopy is a valuable tool for sensing and chemical analysis. Developments in lasers, detectors and mathematical analytical tools have led to improvements in the sensitivity and selectivity of spectroscopic techniques and extended their fields of application. Laser Spectroscopy for Sensing examines these advances and how laser spectroscopy can be used in a diverse range of industrial, medical, and environmental applications. Part one reviews basic concepts of atomic and molecular processes and presents the fundamentals of laser technology for controlling the spectral and temporal aspects of laser excitation. In addition, it explains the selectivity, sensitivity, and stability of the measurements, the construction of databases, and the automation of data analysis by machine learning. Part two explores laser spectroscopy techniques, including cavity-based absorption spectroscopy and the use of photo-acoustic spectroscopy to acquire absorption spectra of gases and condensed media. These chapters discuss imaging methods using laser-induced fluorescence and phosphorescence spectroscopies before focusing on light detection and ranging, photothermal spectroscopy and terahertz spectroscopy. Part three covers a variety of applications of these techniques, particularly the detection of chemical, biological, and explosive threats, as well as their use in medicine and forensic science. Finally, the book examines spectroscopic analysis of industrial materials and their applications in nuclear research and industry. The text provides readers with a broad overview of the techniques and applications of laser spectroscopy for sensing. It is of great interest to laser scientists and engineers, as well as professionals using lasers for medical applications, environmental applications, military applications, and material processing. - Presents the fundamentals of laser technology for controlling the spectral and temporal aspects of laser excitation - Explores laser spectroscopy techniques, including cavity-based absorption spectroscopy and the use of photo-acoustic spectroscopy to acquire absorption spectra of gases and condensed media - Considers spectroscopic analysis of industrial materials and their applications in nuclear research and industry

Available in PDF, EPUB and Kindle. Book excerpt: Laser induced breakdown spectroscopy (LIBS) is basically an emission spectroscopy technique where atoms and ions are primarily formed in their excited states as a result of interaction between a tightly focused laser beam and the material sample. The interaction between matter and high-density photons generates a plasma plume, which evolves with time and may eventually acquire thermodynamic equilibrium. One of the important features of this technique is that it does not require any sample preparation, unlike conventional spectroscopic analytical techniques. Samples in the form of solids, liquids, gels, gases, plasmas and biological materials (like teeth, leaf or blood) can be studied with almost equal ease. LIBS has rapidly developed into a major analytical technology with the capability of detecting all chemical elements in a sample, of real- time response, and of close-contact or stand-off analysis of targets. The present book has been written by active specialists in this field, it includes the basic principles, the latest developments in instrumentation and the applications of LIBS . It will be useful to analytical chemists and spectroscopists as an important source of information and also to graduate students and researchers engaged in the fields of combustion, environmental science, and planetary and space exploration.* Recent research work* Possible future applications* LIBS Principles

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes certain fundamentals of laser-induced breakdown spectroscopy (LIBS) and the experimental results obtained from ultraviolet-visible-near infrared (UV-Vis-NIR) spectra induced by laser ablation of a graphite target. The characteristics of the spectral emission intensities from the different species have been investigated as functions of the ambient pressure, laser irradiance, delay time and distance from the target. Excitation, vibrational and rotational temperatures, as well as ionisation degree and electron number density for some species were estimated. Time-gated spectroscopic studies have allowed estimation of time-of-flight (TOF) and propagation velocities for various emission species.
