Book excerpt: Owing to the ability of the positron to annihilate from a variety of defect-trapped states, positron annihilation spectroscopy (PAS) has been applied increasingly to the characterization and study of defects in materials in recent years. In metals particularly, it has been demonstrated that PAS can yield defect-specific information which, by itself or in conjunction with more traditional experimental techniques, has already made a significant impact upon the determination of atomic-defect properties and the monitoring and characterization of vacancy-like microstructure development, as occurs during post-irradiation annealing. The applications of PAS are now actively expanding to the study of more complex defect-related phenomena in irradiated or deformed metals and alloys, phase transformations and structural disorder, surfaces and near-surface defect characterization. A number of these applications in materials science are reviewed and discussed with respect to profitable future directions.

Available in PDF, EPUB and Kindle. Book excerpt: Vol. 2 of "Progress in Materials Analysis" contains the lectures of the 12th Colloquium on Materials Analysis, Vienna, May 13-15, 1985. Due to the top level international participation from industry and research insti tutions the proceedings offer a survey of the present state and current trends in materials analysis of high actuality. The major topics covered are surface, micro and trace analysis of materials with a special emphasis on metals but also including other materials like ceramics, semiconductors, polymers. According to the strategy of the meeting attention is focussed on an interdisciplinary approach to materials science - combining analytical chemistry, solid state physics and technol ogy. Therefore progress reports on modern analytical technique like SIMS, SNMS, AES, XPS, Positron Annihilation Spectroscopy, EPMA, STEM, LAMMS, etc. are contained as well as presentations on the development of materials. The majority of the contributions centers on the treatment of important problems in materials science and technology by a (mostly sophisticated) combination of physical and chemical analytical techniques.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation embrittlement of nuclear reactor pressure vessel steels results from a high number density of nanometer sized Cu-Mn-Ni rich precipitates (CRPs) and sub-nanometer matrix features, thought to be vacancy-solute cluster complexes (VSC). However, questions exist regarding both the composition of the precipitates and the defect character and composition of the matrix features. We present results of positron annihilation spectroscopy (PAS) and small angle neutron scattering (SANS) characterization of irradiated and thermally aged Fe-Cu and Fe-Cu-Mn alloys. These complementary techniques provide insight into the composition and character of both types of nanoscale features. The SANS measurements indicate populations of CRPs and VSCs in both alloys. The CRPs are coarser in the Fe-Cu alloy and the number densities of CRP and VSC increase with the addition of Mn. The PAS involved measuring both the positron lifetimes and the Doppler broadened annihilation spectra in the high momentum region to provide elemental sensitivity at the annihilation site. The spectra in Fe-Cu-Mn specimens thermally aged to peak hardness at 450 C and irradiated at 288 C are nearly identical to elemental Cu. Positron lifetime and spectrum measurements in Fe-Cu specimens irradiated at 288 C clearly show the existence of long lifetime ((almost equal to)500 ps) open volume defects, which also contain Cu. Thus the SANS and PAS provide a self-consistent picture of nanostructures composed of CRPs and VSCs and tend to discount high Fe concentrations in the CRPs.

Book excerpt: One of the more active areas of research on materials involves the observation and characterization of defects. The discovery of positron localization in vacancy-type defects in solids in the 1960's initiated a vast number of experimental and theoretical investigations which continue to this day. Traditional positron annihilation spectroscopic techniques, including lifetime studies, angular correlation, and Doppler broadening of annihilation radiation, are still being applied to new problems in the bulk properties of simple metals and their alloys. In addition new techniques based on tunable sources of monoenergetic positron beams have, in the last 5 years, expanded the horizons to studies of surfaces, thin films, and interfaces. In the present paper we briefly review these experimental techniques, illustrating with some of the important accomplishments of the field. 40 refs., 19 figs.

This book was released on 2001-10-26 with total page 1915 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook brings together, under a single cover, all aspects of the chemistry, physics, and engineering of surfaces and interfaces of materials currently studied in academic and industrial research. It covers different experimental and theoretical aspects of surfaces and interfaces, their physical properties, and spectroscopic techniques that have been applied to a wide class of inorganic, organic, polymer, and biological materials. The diversified technological areas of surface science reflect the explosion of scientific information on surfaces and interfaces of materials and their spectroscopic characterization. The large volume of experimental data on chemistry, physics, and engineering aspects of materials surfaces and interfaces remains scattered in so many different periodicals, therefore this handbook compilation is needed.The information presented in this multivolume reference draws on two decades of pioneering research on the surfaces and interfaces of materials to offer a complete perspective on the topic. These five volumes-Surface and Interface Phenomena; Surface Characterization and Properties; Nanostructures, Micelles, and Colloids; Thin Films and Layers; Biointerfaces and Applications-provide multidisciplinary review chapters and summarize the current status of the field covering important scientific and technological developments made over past decades in surfaces and interfaces of materials and spectroscopic techniques with contributions from internationally recognized experts from all over the world. Fully cross-referenced, this book has clear, precise, and wide appeal as an essential reference source long due for the scientific community.

This book was released on 2009-12-28 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many good books have been written recently on this new field called biomimetics or bionics, but few exploring simultaneously the characterization and technological processes to produce man-made surfaces with similar properties as the biological ones. Bio-inspired surface structures offer significant commercial potential for the creation of antireflective, self-cleaning and drag reducing surfaces, as well as new types of adhesive systems. This review volume explores how the current knowledge of the biological structures occurring on the surface of moth eyes, leaves, sharkskin, and the feet of reptiles can be transferred to functional technological materials. It analyses how such surfaces can be described and characterized using microscopic techniques and thus reproduced. It also encompasses the important areas of current surface replication techniques and the associated acquisition of good master structures.The book is divided in three sections: an introduction of the skin functions and four functional properties of biological surfaces; physical, chemical and microscopy techniques for describing and characterizing the surfaces; and replication techniques for modifying non-natural surfaces.
