    • C. Jeffrey Brinker + 1 más
    • Inglés
    Sol-Gel Science: The Physics and Chemistry of Sol-Gel Processing presents the physical and chemical principles of the sol-gel process. The book emphasizes the science behind sol-gel processing with a chapter devoted to applications. The first chapter introduces basic terminology, provides a brief historical sketch, and identifies some excellent texts for background reading. Chapters 2 and 3 discuss the mechanisms of hydrolysis and condensation for nonsilicate and silicate systems. Chapter 4 deals with stabilization and gelation of sols. Chapter 5 reviews theories of gelation and examines the predicted and observed changes in the properties of a sol in the vicinity of the gel point. Chapter 6 describes the changes in structure and properties that occur during aging of a gel in its pore liquor (or some other liquid). The discussion of drying is divided into two parts, with the theory concentrated in Chapter 7 and the phenomenology in Chapter 8. The structure of dried gels is explored in Chapter 9. Chapter 10 shows the possibility of using the gel as a substrate for chemical reactions or of modifying the bulk composition of the resulting ceramic by performing a surface reaction (such as nitridation) on the gel. Chapter 11 reviews the theory and practice of sintering, describing the mechanisms that govern densification of amorphous and crystalline materials, and showing the advantages of avoiding crystallization before sintering is complete. The properties of gel-derived and conventional ceramics are discussed in Chapter 12. The preparation of films is such an important aspect of sol-gel technology that the fundamentals of film formation are treated at length in Chapter 13. Films and other applications are briefly reviewed in Chapter 14. Materials scientists and researchers in the field of sol-gel processing will find the book invaluable.

  • Immobilized pH Gradients: Theory and Methodology

    • 1 Edición
    • Volumen 20
    • Pier Giorgio Righetti
    • Inglés
    Immobilized pH gradients (IPG) represent the most advanced development of isoelectric focusing (IEF). Originally developed to overcome all the problems of IEF in soluble amphoteric buffers (CA) (such as pH gradient instability, complexation with CA chemicals, unreproducibility of pH gradients, protein precipitation at the pI), it turned out to be an entirely new technique, quite different in principle and operation from conventional IEF. The book is thus meant to bring the reader up to date with this fast developing field. The book is divided into six chapters containing information on: detailed treatment of all the chemistry of the Immobiline chemicals; theory of pH gradient generation (computer simulations, tables with all the possible pH recipes); all analytical aspects of IPGs, including staining techniques, blotting etc.; two-dimensional maps, with a detailed treatise of advantages and limitations; preparative aspects of IPGs, including comparison with other preparative electrophoretic techniques; some examples of applications, including genetic and forensic analysis, blood polymorphism etc.The book is extensive and up-to-date, while also extensively covering the theory. Clearly written, with easily accessible information, the volume is a worthy asset to the Lab. Techniques series.

    • Inglés
    The book first introduces the reader to the fundamentals of experimental design. Systems theory, response surface concepts, and basic statistics serve as a basis for the further development of matrix least squares and hypothesis testing. The effects of different experimental designs and different models on the variance-covariance matrix and on the analysis of variance (ANOVA) are extensively discussed. Applications and advanced topics (such as confidence bands, rotatability, and confounding) complete the text. Numerous worked examples are presented. The clear and practical approach adopted by the authors makes the book applicable to a wide audience. It will appeal particularly to those with a practical need (scientists, engineers, managers, research workers) who have completed their formal education but who still need to know efficient ways of carrying out experiments. It will also be an ideal text for advanced undergraduate and graduate students following courses in chemometrics, data acquisition and treatment, and design of experiments.

  • Selective Sample Handling and Detection in High-Performance Liquid Chromatography

    • 1 Edición
    • Volumen B
    • K. Zech + 1 más
    • Inglés
    This is the second of a two-volume project which treats the handling, separation and detection of complex samples as an integrated, interconnected process. On the basis of this philosophy the editors have selected those contributions which demonstrate that optimal sample preparation leads to a simplification of detection or reduced demands on the separation process. Throughout the book emphasis is on chemical principles with minimum discussion of the equipment required - an approach which reflects the editors' view that the limiting factor in the analysis of complex samples is an incomplete knowledge of the underlying chemistry rather than the hardware available. This lack of knowledge becomes more evident as the demands for lower detection limits grow, as solving complex matrix problems requires a greater understanding of the chemical interaction between the substance to be analysed and the stationary phase. Thus, apart from one chapter dealing with chemically modified silicas, the main theme of the book is developed in three chapters on sample preparation and three on detection.The opening chapter outlines concentration and chromatography on chemically modified silicas with complexing properties, and gives examples of the use of these phases with organic and inorganic compounds. Chapter II, the first of the three contributions dealing with sample preparation, addresses such questions as whether the prepared sample is representative of the material to be analysed; how to avoid contamination; which separation procedure should be used to avoid tedious sample preparation. Chapter III describes the processing of whole blood for drug analysis. The determination of cyclosporine and its metabolites (an especially difficult case) demonstrates how comprehensive the optimisation of sample preparation must be to successfully perform the analysis. Several other examples are also given. Chapter IV deals with radio-column liquid chromatography and introduces the other theme of the book, i.e. selective detection methods. The widespread use of radioisotopes requires a high degree of purification during the manufacture of the compounds, as well as highly accurate detection methods in biological and biochemical studies.Chapter V continues the theme of selective detection with an overview of post-column reaction detection. The use of immobilised enzymes in post-column reactors or `pumpless' reactor systems for on-line reagent generation after the chromatographic separation step is discussed in detail. Various examples of the separation of biological compounds show how the production of electrochemical reagents and photochemical reaction detection have increased the selectivity of the detection, leading to more economical analytical systems. Selective detection employing luminescence detection techniques is outlined in Chapter VI. The use of immobilised fluorophores or the coupling to photochemical reactions leads to highly selective detection systems which can greatly simplify the sample handling. The final chapter reviews the use of continuous separation techniques in flow injection analysis thus revealing the need for a strong interdisciplinary dependence between sample handling and separation in this area.Written by experienced practitioners, this book will be extremely useful to investigators in many areas of application. Each chapter includes sufficient references to the literature to serve as a valuable starting point for more detailed investigation. The strong emphasis on sample handling makes the book unique in many ways and it will be welcomed by environmental scientists as well as those active in the clinical, pharmaceutical and bioanalytical fields.
