Solid State Proton Conductors by Philippe Knauth


Original Title: Solid State Proton Conductors

Proton conduction can be found in many different solid materials, from organic polymers at room temperature to inorganic oxides at high temperature. Solid state proton conductors are of central interest for many technological innovations, including hydrogen and humidity sensors, membranes for water electrolyzers and, most importantly, for high-efficiency electrochemical energy conversion in fuel cells. Focusing on fundamentals and physico-chemical properties of solid state proton conductors, topics covered include: Morphology and Structure of Solid Acids Diffusion in Solid Proton Conductors by Nuclear Magnetic Resonance Spectroscopy Structure and Diffusivity by Quasielastic Neutron Scattering Broadband Dielectric Spectroscopy Mechanical and Dynamic Mechanical Analysis of Proton-Conducting Polymers Ab initio Modeling of Transport and Structure Perfluorinated Sulfonic Acids Proton-Conducting Aromatic Polymers Inorganic Solid Proton Conductors Uniquely combining both organic (polymeric) and inorganic proton conductors, Solid State Proton Conductors: Properties and Applications in Fuel Cells provides a complete treatment of research on proton-conducting materials.

Nanostructured Materials by Philippe Knauth


Original Title: Nanostructured Materials

Nanostructured Materials: Selected Synthesis Methods, Properties and Applications presents several important recent advances in synthesis methods for nanostructured materials and processing of nano-objects into macroscopic samples, such as nanocrystalline ceramics. This book will not cover the whole spectrum of possible synthesis techniques, which would be limitless, but it presents especially interesting highlights in the domains of research of the editors. Subjects that are covered include the following: *"chimie douce" approaches for preparation of a large variety of nanostructured materials, including metals, alloys, semiconductors and oxides; *hydrothermal synthesis with water as solvent and reaction medium can be specifically adapted to nanostructured materials; *"electrospraying" as a powerful new route for the preparation of nanoparticles, especially of oxides for electroceramics; *nanoparticles processed into nanostructured ceramics, by using dynamic compaction techniques; *applications of nanostructured materials. This book complements the previous volume in this series (P. Knauth, J. Schoonman, eds., Nanocrystalline Metals and Oxides: Selected Properties and Applications, Kluwer, Boston, 2002).

The Reconstruction Of Natural Zeolites by Habbib Ghobarkar


Original Title: The Reconstruction Of Natural Zeolites

More than seventeen years have passed now since Glauco Gottardi and Ermano Galli 1 have published their remarkable book on «NATURAL ZEOLITES» where properties and features of naturally occuring phases then available have been compiled. Several new natural zeolites have been found since then, but also natural counterparts ofzeolites which have only been known as synthesis products. The natural formation conditions of zeolites could only be deduced and estimated from their geological environment at the time when NATURAL ZEOLITES has been published, as zeolite synthesis was mainly focused on procedures at low pressures such as those introduced by Barrer and co workers'. Natural zeolites, however, had only been obtained "occasionally" and systematic study to reconstruct these formation conditions has not been performed ever since. This book is focused on the synthesis of natural zeolites by simulating the natural synthesis conditions in the laboratory which are essentially different in means and results from those obtained by conventional synthesis methods. Although the synthesis in the laboratory has undoubtly a great number of advantages over nature such as the employment of proper precursors or the choice of pressure and temperature in a wide range, the synthesis time is very limited in respect to natural conditions: synthesis times ofyears or even tens ofyears which would be necessary to obtain synthesis results for some zeolites- e.g. at 4°C (deep sea conditions) are rather unrealistic.

Nanocomposites by Philippe Knauth


Original Title: Nanocomposites

Nanocomposites have been receiving more and more attention given the improvement of synthesis techniques and the availability of powerful characterization techniques. The aim of the book is to introduce nanocomposite materials using a broad range of inorganic and organic solids. It also presents recent and not very common developments in especially spectroscopic characterization techniques, including Mössbauer, EXAFS, NMR. This should make the book attractive for a broad range of readers, including chemists and physicists.

Nanocrystalline Metals And Oxides by Philippe Knauth


Original Title: Nanocrystalline Metals And Oxides

Nanostructured materials have at least one dimension in the nanometer range. They became a very active research area in solid state physics and chemistry in recent years with anticipated applications in various domains, including solar cells, electronics, batteries and sensors. Nanocrystalline metals and oxides are dense polycrystalline solids with a mean grain size below 100 nm. This book is intended to give an overview on selected properties and applications of nanocrystalline metals and oxides by leading experts in the field. The first three chapters provide a very complete theoretical treatment of thermodynamics and atom/ion transport for nanocrystalline materials. The following chapters are experts' views on the development of experimental characterization techniques for nanocrystalline solids with emphasis on electroceramic materials. Nanocrystalline Metals and Oxides is intended for a broad range of readers, foremost chemists, physicists and materials scientists. Theoretical physicists and chemists will certainly also profit from this book. The electroceramics and solid state ionics community are particularly addressed, given the main interests of the editors.

Solid State Ionics 2004 by Philippe Knauth


Original Title: Solid State Ionics 2004

This book, first published in 2005, covers a wide range of topics related to solid-state ionics. In particular, it highlights advances in materials for energy and the environment. The book is divided into five parts that emphasize the strong impact of fuel cell and battery research in the field. Part I focuses on solid ionic conductors - experiments and theory. Part II is devoted to solid-state ionic devices and is complementary to the papers on cation and anion conductors. Central attention goes to gas permeation membranes, especially for oxygen and hydrogen. Chemical sensors are the focus of Part III. They are important for ecologically responsible development of mankind, given that pollutant emission control requires reliable and fast detection devices. Materials for fuel cells are addressed in Part IV of the book. The largest cluster of contributions falls to Part V - rechargeable lithium batteries. These electrochemical systems have a huge technological impact on mobile phones, laptops and other portable electronic equipment.

Layered Double Hydroxides by Vicente Rives


Original Title: Layered Double Hydroxides

Layered double hydroxides are one of the variety of names given to a family of layered materials first discovered in Sweden in 1842. These materials are interesting because their layer cations can be changed among a wide selection, and the interlayer anion can also be (nearly) freely chosen. Like cationic clays, they can be pillared and can exchange interlayer species -- thus increasing applications and making new routes to derivatives. The principle areas of application include catalyst support, anion scavengers, polymer stabilisers, and antacids. In the last several years, reviews and studies of LDHs have dealt with these uses. This book aims to update the current body of LDH knowledge from a wide array of views. The first section addresses the synthesis and physiochemical characterisation of these materials, and section two focuses on the applications of LDHs.
