Intercalation in Layered Materials


Book Description

This volume is prepared from lecture notes for the course "Intercalation in Layered Materials" which was held at the Ettore Majorana Centre for Scientific Culture at Erice, Sicily in July, 1986, as part of the International School of Materials Science and Tech nology. The course itself consisted of formal tutorial lectures, workshops, and informal discussions. Lecture notes were prepared for the formal lectures, and short summaries of many of the workshop presentations were prepared. This volume is based on these lecture notes and research summaries. The material is addressed to advanced graduate students and postdoctoral researchers and assumes a background in basic solid state physics. The goals of this volume on Intercalation in Layered Materials include an introduc tion to the field for potential new participants, an in-depth and broad exposure for stu dents and young investigators already working in the field, a basis for cross-fertilization between workers on various layered host materials and with various intercalants, and an elaboration of the complementarity of intercalated layered materials with deliberately structured superlattices.




Intercalated Layered Materials


Book Description

Materials with layered structures remain an extensively investigated subject in current physics and chemistry. Most of the promising technological applications however deal with intercalation compounds of layered materials. Graphite intercalation compounds have now been known for a long time. Intercalation in transition metal dichalcogenides, on the other hand, has been investigated only recently. The amount of information on intercalated layered materials has increased far beyond the original concept for this volume in the series Physics and Chemistry of Materials with Layered Structures. The large size of this volume also indicates how important this field of research will be, not only in basic science, but also in industrial and energy applications. In this volume, two classes of materials are included, generally investigated by different scientists. Graphite intercalates and intercalates of other inorganic com pounds actually constitute separate classes of materials. However, the similarity between the intercalation techniques and some intercalation processes does not justify this separation, and accounts for the inclusion of both classes in this volume. The first part of the volume deals with intercalation processes and intercalates of transition metal dichalcogenides. Several chapters include connected topics necessary to give a good introduction or comprehensive review of these types of materials. Organic as well as inorganic intercalation compounds are treated. The second part includes contributions concerning graphite intercalates. It should be noted that graphite intercalation compounds have already been mentioned in Volumes I and V.

Intercalation Chemistry


Book Description

Intercalation Chemistry introduces the specialist reader to the breadth of intercalation chemistry and the newcomer to the diverse research opportunities and challenges available in synthetic and reaction chemistry and also in the controlled modification of physical properties. Topics covered range from graphite chemistry to sheet silicate intercalates, diffusion and shape-selective catalysis in zeolites, organic and organometallic intercalation compounds of the transition metal dichalcogenides, and solvated intercalation compounds of layered chalcogenide and oxide bronzes. This book is comprised of 18 chapters and begins with an introduction to intercalation chemistry. The discussions that follow focus on the intercalation chemistry of graphite and of complex oxides with both two (clays and acid phosphates)- and three (zeolites)-dimensional structures, along with organic conversions that have been discovered using essentially smectite (i.e., montmorillonite- and hectorite-based) intercalates. The next chapters focus on ß-aluminas, acid salts of tetravalent metals with layered structure, and layered chalcogenides and halides with simple and hydrated cations as well as organic and organometallic ions. The book also considers the chemistry, thermodynamics, and applications of intermetallic compounds that incorporate hydrogen, intercalation in the context of biological systems, crystallographic shear structures, and intercalation reactions of oxides and chalcogenides of vanadium, molybdenum, and tungsten. The final chapter touches on the physical properties of some intercalation compounds of the dichalcogenides. This book is intended for researchers in the various materials science disciplines.

Graphite Intercalation Compounds I


Book Description

The progress of materials science depends on the development of novel materials and the development of novel experimental techniques. The research on graphite intercalation compounds combines both aspects: new compounds with strikingly new and anisotropic properties have been synthesized and analyzed during the past couple of years by means of state-of-the-art experimental methods. At the same time, the preparation of the compounds already known has improved con siderably, giving increased reliability and reproducibility of the experimental results. The high quality experimental data now available have stimulated theo retical work. Moreover, the theoretical work has had a great impact on further experimental studies, with the effect of a much improved understanding of this class of materials. This volume is dedicated to a thorough description of all relevant experimen tal and theoretical aspects of the structural and dynamical properties of graphite intercalation compounds. Because of the large number of topics, a second vol ume, which is now in preparation, will follow and will treat the electronic, transport, magnetic, and optical properties. The second volume will also contain a chapter on applications of graphite intercalation compounds. There have been a number of reviews written on selected aspects of these compounds in various journals and conference proceedings during the last couple of years, but this is the first comprehensive review since the thorough overview provided by M.S. Dresselhaus and G. Dresselhaus appeared ten years ago.

Applications of Layered Double Hydroxides


Book Description

"Currently, Layered Double Hydroxides (LDH) is a hot area of research on inorganic layered materials. The present book, Applications of Layered Double Hydroxides, edited by Dr. Rjib Lochan Goswamee and Dr. Pinky Saikia, is a collection of articles from various researchers from different parts of the world mainly on structure and property relationships of various types of LDH and their related application prospects. How these application prospects can be related to the most pressing problems of humanity like drug delivery, global warming, green catalysis, electrochemical energy storage and generation etc. are clearly discussed in the articles inside. The book provides a thorough up-to-date review of recent literature on applications of LDH available in the global scientific and technical media. For example, the book lucidly describes the behaviour of LDH nanocarriers in biological fluids, their low cytotoxicity and high levels of cellular internalization, and high drug loading capacity. Similarly, the book examines why hybrid nanocomposites of LDH-MOF are considered promising materials due to their diverse functionality, flexible properties and tailored end-use properties. Likewise, application of LDH in secondary batteries and electro-chemical supercapacitors with a thorough up-to-date review is included in the book. Also, basic research articles on structural properties and measurements of a special class of unique LDH Li-Al-LDHs are included. Editors also have written their own articles on their findings on the prospective application of dispersions of LDH nanocomposites on structured catalysts for green-house gas emission. Overall, the book gives a short glimpse of wonderful opportunities that LDH can provide in solving many global socio-economic problems of today"--




Chemical Physics of Intercalation


Book Description

Conjugated polymers suoh as polyaoetylene (CH)x polyphenylene (C6H4)x' poly thiophene (C4H2S)x' etc., which are insulators in their pristine state, can be brought to the metallic state after "doping" with ohemioal speoies whioh oan be either eleotron donors or I aoceptors. . This doping prooess involves a oharge transfer between the dopant moleoule and the polymer ohain whioh are then supposed to be spatially olose to each other. It follows that the meohanism of doping must be oonsidered as an aotual interoalation process, which will greatly affeot the struotural oharacteristios of the starting material, as well as its morphology, as has been observed during the 2 intercalation of graphite and layered compounds . In parallel with these modifioations, the band struoture of the system changes yielding a new set of eleotronio properties. It is evident therefore that the struotural and eleotronio properties are intimately related, and must be studied simultaneously in the same system to give reliable information. A great number of studies have been devoted to the structural and electronic properties of conjugated polymers after a chemical or 2 electrochemical doping process . Most of these concern the properties of the system for a given dopant concentration. With this approach a universal pioture of the polymer/dopant system is very diffioult to obtain, as a comparison between different experiments is very hazardous. On the other hand, only a small number of measurements have been performed during the continuous electroohemioal doping of various polymers.
