This book investigates applicability of various emerging strategies to improve important properties and features of metal oxide materials that can be used further to advance their photocatalytic and photoelectrochemical performances. The range of discussed strategies includes introduction of intrinsic and extrinsic deficiencies, fabrication of heterojunction and utilizing of metal nanoparticles in the form of deposited or embedded formations. Each of them is addressed as separate case in order to reach full and comprehensive assessment of their most fundamental principles and basics as well as accessing pivotal advantages and disadvantages. Furthermore, additional discussion is dedicated to achieving thorough awareness over methods and experimental protocols that are used to realize them and also probing changes which they induce in electronic and geometrical configurations of metal oxide materials. It is believed that this book might become a valuable addition to extend further current knowledge about photocatalysis and material processing.

Polaritonic chemistry is an emergent interdisciplinary field in which the strong interaction of organic molecules with confined electromagnetic field modes is exploited in order to manipulate the chemical structure and reactions of the system. In the regime of strong light-matter coupling the interaction with the electromagnetic vacuum obliges us to redefine the concept of a molecule and consider the hybrid system as a whole. This thesis builds on the foundations of chemistry and quantum electrodynamics in order to provide a theoretical framework to describe these organic light-matter hybrids. By fully embracing the structural complexity of molecules, this theory allows us to employ long-established quantum chemistry methods to understand polaritonic chemistry. This leads to predictions of substantial structural changes in organic molecules and the possibility of significantly influencing chemical reactions both in the excited and ground states of the system.

This book tells the story of two of the most important figures in the history of chemistry. Carl Wilhelm Scheele (1742-1786) was the first to prepare oxygen and realise that air is a mixture of nitrogen and oxygen; he also discovered many important organic and inorganic substances. His fellow chemist and good friend, Torbern Bergman (1735-1784), was one of the pioneers in analytical and physical chemistry. In this carefully researched biography, the author, Anders Lennartson, explains the chemistry of Scheele and Bergman while putting their discoveries in the context of other 18th-century chemistry. Much of the information contained in this work is available in English for the first time.

The book will be of interest to researchers in academia and industry alike.

The history of the rare earths has entered its third century; trans uranium elements are now a half century old. Both the lanthanide and actinide ele- ments, 30 elements altogether, are f elements, meaninj that their metallic 2 1 1 electronic configurations are typically 6s 5d 4f" and 7s 6d 5f" respectively. To an elementary approximation as summarized in the 'average inorganic chemistry textbook, these configurations cause their chemistry to be described by the trivalent state accompanied by less interesting effects such as the lanthanide contraction. However, the discovery of divalent and tetravalent lanthanides and di- to seven-valent actinides hinted at the existence of more interesting although still classic solid-state and coor- dination chemistry. Metallic halides and chalcogenides and electron-poor cluster compounds have been the outgrowth of many synthetic efforts during the past 25 years or so. These days, one can say that the lan- thanides and actinides are not at all boring; the fascination arises from every element being an individual, having its own chemistry.

This book focuses on theoretical and computational studies by the editor's group on the direct hydroxylation of methane, which is one of the most challenging subjects in catalyst chemistry. These studies of more than 20 years include gas-phase reactions by transition-metal oxide ions, enzymatic reactions by two types of methane monooxygenase (soluble and particulate MMO), catalytic reactions by metal-exchanged zeolites, and methane C-H activation by metal oxide surfaces. Catalyst chemistry has been mostly empirical and based on enormous experimental efforts. The subject of the title has been tackled using the orbital interaction and computations based on extended Huckel, DFT, and band structure calculations. The strength of the theoretical studies is in the synergy between theory and experiment. Therefore, the group has close contacts with experimentalists in physical chemistry, catalyst chemistry, bioinorganic chemistry, inorganic chemistry, and surface chemistry. This resulting book will be useful for the theoretical analysis and design of catalysts.

This volume presents recent advances and current knowledge in the field of supramolecular assemblies based on electrostatic interactions. The flexibility and simplicity of constructing assemblies is explained via several examples, illustrations, figures, case studies, and historical perspectives. Moreover, as there is an increasing demand for the use of theoretical and computational models of the interaction strengths for assisting with the experimental studies, one chapter specifically focuses on the "modelling'' of supramolecular assemblies. Finally, various aspects of the recent advances of the field as well as potential future opportunities are discussed, with the goal being to stimulate critical discussions among the community and to encourage further discovery. This volume aims to inspire and guide fellow scientists and students working in this field and thus it provides a great tool for all researchers, graduates and professionals specializing on the topic.

This book provides a systematic description of the molecular structures and bonding in simple compounds of the main group elements with particular emphasis on bond distances, bond energies and coordination geometries. The description includes the structures of hydrogen, halogen and methyl derivatives of the elements in each group, some of these molecules are ionic, some polar covalent. The survey of molecules whose structures conform to well-established trends is followed by representative examples of molecules that do not conform. We also describe electron donor-acceptor and hydrogen bonded complexes. Chemists use models to systematize our knowledge, to memorize information and to predict the structures of compounds that have not yet been studied. The book provides a lucid discussion of a number of models such as the Lewis electron-pair bond and the VSEPR models, the spherical and polarizable ion models, and molecular orbital calculations, and it outlines the successes and failures of each.

Also included in this collection is the design of extraction equipment used in these processes from suppliers as well as laboratory and pilot plant studies.

Practical skills form the cornerstone of chemistry. However, the diversity of skills required in the laboratory means that a student's experience may be limited. While some techniques do require specific skills, many of them are transferable generic skills that are required throughout the subject area. Limited time constraints of the modern curriculum often preclude or minimise laboratory time. Practical Skills in Chemistry 3rd edition provides a general guidance for use in and out of practical sessions, covering a range of techniques from the basic to the more advanced. This 'one-stop' text will guide you through the wide range of practical, analytical and data handling skills that you will need during your studies. It will also give you a solid grounding in wider transferable skills such as teamwork, using information technology, communicating information and study skills. This edition has been enhanced and updated throughout to provide a complete and easy-to-read guide to the developing skills required from your first day through to graduation, further strengthening its reputation as the practical resource for students of chemistry and related discipline areas.

This book summarizes and records the recent notable advances in diverse topics in organic crystal chemistry, which has made substantial progress along with the rapid development of a variety of analysis and measurement techniques for solid organic materials. This review book is one of the volumes that are published periodically on this theme. The previous volume, published in 2015, systematically summarized the remarkable progress in assorted topics of organic crystal chemistry using organic solids and organic-inorganic hybrid materials during the previous 5 years, and it has been widely read. The present volume also shows the progress of organic solid chemistry in the last 5 years, with contributions mainly by invited members of the Division of Organic Crystal Chemistry of the Chemical Society of Japan (CSJ), together with prominent invited authors from countries other than Japan.

Furthermore, it presents up-to-date information on the economics, toxicity, and regulations related to these novel materials.

This book provides an intuitive yet sound understanding of how structure and properties of solids may be related. The natural link is provided by the band theory approach to the electronic structure of solids. The chemically insightful concept of orbital interaction and the essential machinery of band theory are used throughout the book to build links between the crystal and electronic structure of periodic systems. In such a way, it is shown how important tools for understanding properties of solids like the density of states, the Fermi surface etc. can be qualitatively sketched and used to either understand the results of quantitative calculations or to rationalize experimental observations. Extensive use of the orbital interaction approach appears to be a very efficient way of building bridges between physically and chemically based notions to understand the structure and properties of solids.

The study of clusters is one of the most exciting topics in the rapidly developing field of nanostructured materials. As discussed in this book, nanometer-sized metal particles can be obtained not only by evaporation methods, producing atomic or molecular beams, but also by the chemical synthesis of metal cluster compounds. These have a well-defined stoichiometry and are composed of metal clusters of a given, homogeneous size, each cluster being surrounded by a shell of ligand molecules. Accordingly, the compounds provide excellent model systems for macroscopic assemblies of small metal particles embedded in a dielectric solid. The underlying physical properties are described in terms of a three-dimensional matrix of mutually separated quantum wells. In going from one compound to another, the size and separation of the quantum wells may be varied. In this way, one may study such fundamental properties as the size-induced transition from metallic to molecular behaviour. At the same time, the electronic level structure may be changed in a controlled way, which should confer tunable optical, electrical or magnetic properties.

Comprehensive Supramolecular Chemistry II, Second Edition, Nine Volume Set is a ‘one-stop shop’ that covers supramolecular chemistry, a field that originated from the work of researchers in organic, inorganic and physical chemistry, with some biological influence. The original edition was structured to reflect, in part, the origin of the field. However, in the past two decades, the field has changed a great deal as reflected in this new work that covers the general principles of supramolecular chemistry and molecular recognition, experimental and computational methods in supramolecular chemistry, supramolecular receptors, dynamic supramolecular chemistry, supramolecular engineering, crystallographic (engineered) assemblies, sensors, imaging agents, devices and the latest in nanotechnology. Each section begins with an introduction by an expert in the field, who offers an initial perspective on the development of the field. Each article begins with outlining basic concepts before moving on to more advanced material.

This includes water in clusters, particles, films, and at surfaces and interfaces. The topics covered range from the molecular to condensed phases and involve both liquid and solid phases. Emphasis is on systems for which the extent of water is limited so that the surface/interface of the water may be critical to the properties of the system. The main sections include: theoretical studies of intermolecular interactions; neutral and ionic water clusters; solid and liquid water surfaces and interfaces; amorphous ice layers; ice and water particles; water in bio-systems; and atmospheric water.

Functional materials research is one of the high priority strategic areas of - st velopmentinscienceandtechnologyinthe21 century.Amongstthevarietyof functions,theinteractionofmatterwithlighttogeneratelight-drivenorpho- responsive properties has always been one of the most appealing and attr- tive areas. Recent advances in the exploitation of transition metal complexes in bringing about photo-induced functions have attracted growing attention, particularly in areas related to materials, energy, and biomedical research. Selected examples include the development of molecular triplet emitters for organic light-emitting devices (OLEDs), optical and photo-switches, pho- chemical energy storage, dye-sensitized solar cells, photochemical molecular devices(PMD)andmachines,opticalandluminescenceprobesandchemos- sors,luminescentlabelsandtagsforbiomolecules,andluminescencesignaling and imaging. This volume serves to provide the readers with some fundamentals of - minescent transition metal complexes and the recent exciting developments of a selected variety of functions and potential applications that transition metal complexes can offer for the betterment of the society in areas related to materials, energy, and biomedical research. The ?rst chapter of this volume by Balch discussed the current progress in two-coordinate luminescent gold(I) complexes. This class of complexes is well-known to show weak metal***metal interactions that lead to the iso- tionofnovel architecturesand polymorphism fromrelatively simple building blocksandtheappearanceofuniqueelectronicabsorptionandemissionsp- troscopicfeatures.Theeffectoftheenvironment,suchassolventsandcounter ions, on the luminescence behavior of a number of two-coordinate gold(I) complexes was discussed.

Written by the founder of the field of carbon "quantum" dots (carbon dots) and related technology, this book outlines the principles of carbon dots and presents strong evidence for that small carbon nanoparticles and by extension carbon dots represent the nanoscale carbon allotrope at zero-dimension. Historical accounts of the inception and evolution of the carbon dots field are provided. Experimental approaches and techniques for the dot synthesis and some related major issues are discussed in detail. The photoexcited state properties, especially the bright and colorful photoluminescence emissions, and photoinduced redox characteristics of carbon dots are presented, and so are their advantages over semiconductor quantum dots as well as fullerenes. Carbon dots are also compared with "graphene quantum dots", for which a unified mechanistic understanding is proposed. Finally, a broad range of applications of carbon dots and their derived hybrid nanostructures in biomedical, renewable energy, food and environmental safety, and other technologies are highlighted. The book concludes with a discussion on the excellent potential and opportunities for further research and development.

Some 20 years ago, I was privileged to share in writing a book on the descriptive chemistry of the 4d, 5d, 4f and 5f metals that included these eight elements within its compass (S.A. Cotton and F.A. Hart, The Heavy Transition Elements, Macmillan, 1975). This volume shares the same aim of covering the descriptive chemistry of silver, gold and the six platinum metals in some detail at a level suitable for advanced undergraduate and postgraduate study. It does not attempt to be a comprehensive treatise on the chemistry of these metals. It attempts to fill a slot between the general text and the in-depth review or monograph. The organometallic chemistry is confined to a-bonded com pounds in normal oxidation states; compounds with IT-bonding ligands are generally excluded. Their inclusion would have increased the length of the book considerably and, moreover, their recent chemistry has been extensively and expertly reviewed in the new Comprehensive Organometallic Chemistry, II, eds G. Wilkinson, F.G.A. Stone and E.W. Abel, Pergamon, Oxford, 1995."

This thesis describes the synthesis and characterization of numerous metal-metal bonded complexes that are stabilized by extremely bulky amide ligands.
