Specimen Handling Preparation And Treatments In Surface Characterization

With the development in the 1960s of ultrahigh vacuum equipment and techniques and electron, X-ray, and ion beam techniques to determine the structure and composition of interfaces, activities in the field of surface science grew nearly exponentially. Today surface science impacts all major fields of study from physical to biological sciences, from physics to chemistry, and all engineering disciplines. The materials and phenomena characterized by surface science range from se- conductors, where the impact of surface science has been critical to progress, to metals and ceramics, where selected contributions have been important, to bio- terials, where contributions are just beginning to impact the field, to textiles, where the impact has been marginal. With such a range of fields and applications, questions about sample selection, preparation, treatment, and handling are difficult to cover completely in one review article or one chapter. Therefore, the editors of this book have assembled a range of experts with experience in the major fields impacted by surface characterization. It is the only book which treats the subject of sample handling, preparation, and treatment for surface characterization. It is full of tricks, cautions, and handy tips to make the laboratory scientist’s life easier. With respect to organization of the book, the topics range from discussion of vacuum to discussion of biological, organic, elemental or compound samples, to samples prepared ex situ or in situ to the vacuum, to deposition ofthin films. Generic considerations of sample preparation are also given.

In his thesis, Florian Schweinberger investigates the influence of the precise size of catalytically active species on reactivity. In order to do this he carries out studies both in UHV and under ambient conditions for supported, size-selected Platium clusters (8-68 atoms). Schweinberger probed the electronic structure, adsorption properties and reactivity of two olefins on surfaces and Pt clusters in the submonolayer range. With adsorbed trichloroethene (TCE) a possible cluster-adsorbate induced change in the electronic structure, and for ethene a low-temperature, size-dependent self-/hydrogenation was observed.In a collaborative approach, Schweinberger and colleagues investigated Pt clusters under ambient pressure conditions. They characterised the clusters at at the local and integral level and tested for temperature stability. Experiments in gas phase ?-reactors and in liquid, as part of a hybrid photocatalytic system, revealed size-dependent reactivity.Overall this thesis is not only of interest for those who want to perform similar experiments but also provides superb scientific insights for researchers in the field.

"Surface Characterization" provides an authoritative guide to the wide range of powerful techniques that are used to characterize the surfaces of materials. Practical in approach, it not only describes the major analytical techniques but emphasizes how they can be used to solve a multitude of chemical and physical problems. A special feature of the book is that the various techniques are grouped according to the material property under investigation. These parts are preceded by an overview comparing the capabilities of the characterization methods available. Extensive data tables allow the reader to assess rapidly the strengths as well as the pitfalls inherent in each method. Chapters on chemical composition, optical and crystallographic properties, microtopography, surface processes, tribological, electrical and magnetic properties of surface films are featured. In addition, chapters specializing on applications within the life sciences on the microscopic scale and chemometrics are included. "Surface Characterization" is addressed to both academic and industrial audiences. Scientists and engineers working on the production and development of new materials will find it an invaluable reference source. Physicist, chemists, chemical engineers, material scientists and engineers from every area of materials research will benefit from the wealth of practical advice the book provides.

"Outlines the scientific basis and experimental methods for a broad sample of surface analysis techniques, drawing heavily from established principles of physical and analytical chemistry. Sketches a simple low-cost method of tracking particles in three dimensions."

This book highlights the failure theories and evaluation techniques of thermal barrier coatings, covering the thermal-mechanical–chemical coupling theories, performance and damage characterization techniques, and related evaluations. Thermal barrier coatings are the key thermal protection materials for high-temperature components in advanced aeroengines. Coating spallation is a major technical bottleneck faced by researchers. The extremely complex microstructure, diverse service environments, and failure behaviors bring challenges to the spallation analysis in terms of the selective use of mechanical theories, experimental methods, and testing platforms. In the book, the authors provide a systematic summary of the latest research and technological advances and present their insights and findings in the past couple of decades. This book is not only suitable for researchers and engineers in thermal barrier coatings and related fields but also a good reference for upper-undergraduate and postgraduate students of materials science and mechanics majors.

This book covers 10 surface characterization techniques divided into three sections. The first section covers the theoretical background, instrumentation and their salient features and a general understanding behind the results. The second section delves into deeper discussion of every terminology and concept. The third section is composed of 5 sets of examples from different research papers for every technique.

Despite having powerful software, microchips, and solid-state detectors that enable analytical chemists to achieve fast, stable, and accurate signals from their instruments, sample preparation is the most important step in chemical analysis. Issues can arise at this step for various reasons, including a low concentration of analytes, incompatibility of the sample with the analytical instrument, and matrix interferences. This volume discusses the basics of sample preparation and examines modern techniques that can be used by both novice and expert analytical chemists. Chapters review microextraction, surface spectroscopy analysis, and techniques for particle, tissue, and cellular separation.

A better understanding of the microstructure of metals and alloys has led to great advances in the performance and useful applications of these, the oldest of mankind's engineered materials. This book in the Materials Characterizations series focuses on the particular molecular and atomistic properties of metals insofar as how they affect the different techniques for measuring and analyzing internal structure, surface structure, and chemical/physical properties. It provides a vital connection between commonly used characterization techniques like Scanning Electron Microscopy and how such can be used in the various ways that metals are processed, machined, and used. Review of relevant mechanical and chemical properties of metals and how they affect characterization techniques Characterization techniques used for melting and casting, machining, and metallic thin films processes Concise summaries of major characterization technologies for metals and alloys, including Auger Electron Spectroscopy, Energy-Dispersive X-Ray Spectroscopy, Neutron Activation Analysis, Scanning Electron Microscopy, and Transmission Electron Spectroscopy
