This book provides microscopic insights into chemical properties of NO on metal surfaces. NO/metal systems have been studied intensively to understand heterogeneous catalysis to detox exhaust NOx gas. The identification and componential analysis of various and mixed chemical species of NO adsorbed onto the surfaces have been significant challenges faced by conventional experimental techniques, such as vibrational spectroscopies. The author investigated "individual" NO molecules on Cu surfaces using low-temperature scanning tunneling microscopy (STM). STM not only provides information on the geometric, electronic, and vibrational properties at the single-molecule level; it is also able to manipulate molecules on surfaces to induce chemical reaction. Exploiting those techniques, the author chemically identified individual NO-related species on the surfaces and discovered new reaction processes for NO reduction, which provides microscopic insights into the catalytic mechanisms. The author also visualized wave functions of electrons in a valence orbital of NO and demonstrated that the wave functions are modified by the formation of covalent bonding or hydrogen bonding. This is, namely, "the visualization of quantum mechanics in real space," which is certainly worth reading. Furthermore, the book demonstrates that direct observation of valence orbitals helps to elucidate the reactivity of molecules adsorbed onto surfaces. This innovative approach to studying molecular properties will contribute to further development of STM and its related methods.

R2,851 Discovery Miles 28 510 Ships in 10 - 15 working days

This book presents a collection of invited research and review contributions on recent advances in (mainly) theoretical condensed matter physics, theoretical chemistry, and theoretical physics. The volume celebrates the 90th birthday of N.H. March (Emeritus Professor, Oxford University, UK), a prominent figure in all of these fields. Given the broad range of interests in the research activity of Professor March, who collaborated with a number of eminent scientists in physics and chemistry, the volume embraces quite diverse topics in physics and chemistry, at various dimensions and energy scales. One thread connecting all these topics is correlation in aggregated states of matter, ranging from nuclear physics to molecules, clusters, disordered condensed phases such as the liquid state, and solid state physics, and the various phase transitions, both structural and electronic, occurring therein. A final chapter leaps to an even larger scale of matter aggregation, namely the universe and gravitation. A further no less important common thread is methodological, with the application of theoretical physics and chemistry, particularly density functional theory and statistical field theory, to both nuclear and condensed matter.

R2,789 Discovery Miles 27 890 Ships in 10 - 15 working days

This book reports on the successful implementation of an innovative, miniaturized galvanic cell that offers unprecedented control over and access to ionic transport. It represents a milestone in fundamental studies on the diffusive transport of lithium ions between two atomically thin layers of carbon (graphene), a highly relevant aspect in electrodes for energy and mass storage in the context of batteries. Further, it is a beautiful example of how interdisciplinary work that combines expertise from two very distinct fields can significantly advance science. Machinery and tools common in the study of low-dimensional systems in condensed matter physics are combined with methods routinely employed in electrochemistry to enable truly unique and powerful experiments. The method developed here can easily be generalized and extended to other layered materials as well as other ionic species. Not only the method but also the outcome of its application to Li diffusion and intercalation in bilayer graphene is remarkable. A record chemical diffusion coefficient is demonstrated, exceeding even the diffusion of sodium chloride in water and surpassing any reported value of ion diffusion in single-phase mixed conducting materials. This finding may be indicative of the exceptional properties yet to be discovered in nanoscale derivatives of bulk insertion compounds.

R7,138 Discovery Miles 71 380 Ships in 12 - 17 working days

This book explains how the partial differential equations (pdes) in electroanalytical chemistry can be solved numerically. It guides the reader through the topic in a very didactic way, by first introducing and discussing the basic equations along with some model systems as test cases systematically. Then it outlines basic numerical approximations for derivatives and techniques for the numerical solution of ordinary differential equations. Finally, more complicated methods for approaching the pdes are derived. The authors describe major implicit methods in detail and show how to handle homogeneous chemical reactions, even including coupled and nonlinear cases. On this basis, more advanced techniques are briefly sketched and some of the commercially available programs are discussed. In this way the reader is systematically guided and can learn the tools for approaching his own electrochemical simulation problems. This new fourth edition has been carefully revised, updated and extended compared to the previous edition (Lecture Notes in Physics Vol. 666). It contains new material describing migration effects, as well as arrays of ultramicroelectrodes. It is thus the most comprehensive and didactic introduction to the topic of electrochemical simulation.

R2,789 Discovery Miles 27 890 Ships in 10 - 15 working days

This thesis proposes a novel way to catch light energy using an ultrasmall nanostructure. The author has developed photon-materials systems to open the way for novel photoexcitation processes based on the findings obtained from in-situ observation of the systems in which localized surface plasmon (LSP) and molecules interact strongly. The highly ordered metal nanostructure provided the opportunity for anisotropic photoexcitation of materials in an eccentric way. The optimization of the systems via nanostructuring and electrochemical potential control resulted in the novel excitation process using LSP to realize the additional transition for photoexcitation. Furthermore, excited electronic states formed the strong coupling between LSP and excitons of molecules. This thesis will provide readers with an idea for achieving very effective processes for photon absorption, scattering, and emission beyond the present limits of photodevices.

R6,960 Discovery Miles 69 600 Ships in 12 - 17 working days

Modeling of Chemical Reactions covers detailed chemical kinetics models for chemical reactions. Including a comprehensive treatment of pressure dependent reactions, which are frequently not incorporated into detailed chemical kinetic models, and the use of modern computational quantum chemistry, which has recently become an extraordinarily useful component of the reaction kinetics toolkit.
It is intended both for those who need to model complex chemical reaction processes but have little background in the area, and those who are already have experience and would benefit from having a wide range of useful material gathered in one volume. The range of subject matter is wider than that found in many previous treatments of this subject. The technical level of the material is also quite wide, so that non-experts can gain a grasp of fundamentals, and experts also can find the book useful.
* A solid introduction to kinetics
* Material on computational quantum chemistry, an important new area for kinetics
* Contains a chapter on construction of mechanisms, an approach only found in this book

Biological Complexity and the Dynamics of Life Processes, Volume 34 (Hardcover): J. Ricard Biological Complexity and the Dynamics of Life Processes, Volume 34 (Hardcover)
J. Ricard
R4,629 Discovery Miles 46 290 Ships in 12 - 17 working days

The aim of this book is to show how supramolecular complexity of cell organization can dramatically alter the functions of individual macromolecules within a cell. The emergence of new functions which appear as a consequence of supramolecular complexity, is explained in terms of physical chemistry.
The book is interdisciplinary, at the border between cell biochemistry, physics and physical chemistry. This interdisciplinarity does not result in the use of physical techniques but from the use of physical concepts to study biological problems.
In the domain of complexity studies, most works are purely theoretical or based on computer simulation. The present book is partly theoretical, partly experimental and theory is always based on experimental results. Moreover, the book encompasses in a unified manner the dynamic aspects of many different biological fields ranging from dynamics to pattern emergence in a young embryo.
The volume puts emphasis on dynamic physical studies of biological events. It also develops, in a unified perspective, this new interdisciplinary approach of various important problems of cell biology and chemistry, ranging from enzyme dynamics to pattern formation during embryo development, thus paving the way to what may become a central issue of future biology.

This volume summarises recent developments and possible future directions for small molecule X-ray crystallography. It reviews specific areas of crystallography which are rapidly developing and places them in a historical context. The interdisciplinary nature of the technique is emphasised throughout. It introduces and describes the chemical crystallographic and synchrotron facilities which have been at the cutting edge of the subject in recent decades. The introduction of new computer-based algorithms has proved to be very influential and stimulated and accelerated the growth of new areas of science. The challenges which will arise from the acquisition of ever larger databases are considered and the potential impact of artificial intelligence techniques stressed. Recent advances in the refinement and analysis of X-ray crystal structures are highlighted. In addition the recent developments in time resolved single crystal X-ray crystallography are discussed. Recent years have demonstrated how this technique has provided important mechanistic information on solid-state reactions and complements information from traditional spectroscopic measurements. The volume highlights how the prospect of being able to routinely "watch" chemical processes as they occur provides an exciting possibility for the future. Recent advances in X-ray sources and detectors that have also contributed to the possibility of dynamic single-crystal X-ray diffraction methods are presented. The coupling of crystallography and quantum chemical calculations provides detailed information about electron distributions in crystals and has resulted in a more detailed understanding of chemical bonding. The volume will be of interest to chemists and crystallographers with an interest in the synthesis, characterisation and physical and catalytic properties of solid-state materials. Postgraduate students entering the field will benefit from a historical introduction to the subject and a description of those techniques which are currently used. Since X-ray crystallography is used so widely in modern chemistry it will serve to alert senior chemists to those developments which will become routine in coming decades. It will also be of interest to the broad community of computational chemists who study chemical systems.

A companion volume to "Conceptual Trends in Quantum Chemistry", this work contains eight contributions focusing on important conceptual trends in atomic and molecular theory. The "polarization" between ab initio and semi-empirical methods is thoroughly analyzed in two of the articles, which also provide bridges between such procedures. Hydrogen-transfer theory and electron delocalization are treated in two further papers. Explicitly time-dependent descriptions of intermolecular dynamics, which constitute a characteristic trend in current research, are represented by an article about the quantum dynamics of diatoms in external fields. A view of certain atomic excited states is presented in a paper on collective and independent particle character, and a new theoretical tool is surveyed in an article on dimensional scaling. The final article analyzes density functional theory.

R2,789 Discovery Miles 27 890 Ships in 10 - 15 working days

This work revolves around the hydrogen economy and energy-storage electrochemical systems. More specifically, it investigates the possibility of using magnetron sputtering for deposition of efficient thin-film anode catalysts with low noble metal content for proton exchange membrane water electrolyzers (PEM-WEs) and unitized regenerative fuel cells (PEM-URFCs). The motivation for this research derives from the urgent need to minimize the price of such electrochemical devices should they enter the mass production. Numerous experiments were carried out, correlating the actual in-cell performance with the varying position of thin-film catalyst within the membrane electrode assembly, with the composition of high-surface support sublayer and with the chemical structure of the catalyst itself. The wide arsenal of analytical methods ranging from electrochemical impedance spectroscopy through electrochemical atomic force microscopy to photoelectron spectroscopy allowed the description of the complex phenomena behind different obtained efficiencies. Systematic optimizations led to the design of a novel PEM-WE anode thin-film iridium catalyst which performs similarly to the standard counterparts despite using just a fraction of their noble metal content. Moreover, the layer-by-layer approach resulted in the design of a Ir/TiC/Pt bi-functional anode for PEM-URFC which is able to operate in both the fuel cell and electrolyzer regime and thus helps to cut the cost of the whole conversion system even further.
