This book explores the possibility of using micro/nanostructures formed on the doped ice surface as a novel separation platform. In addition, it provides comprehensive information on the nature of freeze-concentrated solutions (FCSs) and the ice/FCS interface, which play important roles in the natural environment and industrial processes alike. The book proposes a novel size-selective separation approach using channels formed on the doped ice surface. The separation is based on the physical interaction of analytes with channel walls, which is controlled by varying the channel width through temperature and dopant concentration changes. It also shows the precise control of the channel width to be in a range of 200 nm-4 m and demonstrates the size-selective separation of microspheres, cells, and DNA. The physicochemical properties of FCSs are measured to reveal the nature of the ice/FCS interface, and the zeta potentials of ice are measured by determining EOF rates in a microchannel fabricated in the ice. The deprotonation at OH dangling bonds and adsorption of ions are also discussed. The viscosities of FCSs confined in micro/nanospaces are evaluated by means of two spectroscopic methods. When an FCS is confined in small spaces surrounded by ice, the viscosity increases compared to that in a bulk solution. Interestingly, this viscosity enhancement occurs even though its size is on the micrometer scale. These parameters are essential to discussing the unique phenomena occurring in FCSs. This book provides an explanation of the scientific processes taking place in FCSs, and reveals the potential that frozen solutions hold as innovative micro/nanofluidic devices and reaction platforms.

Come on a journey into the heart of matter,and enjoy the process!,as a brilliant scientist and entertaining tour guide takes you on a fascinating voyage through the Periodic Kingdom, the world of the elements. The periodic table, your map for this trip, is the most important concept in chemistry. It hangs in classrooms and labs throughout the world, providing support for students, suggesting new avenues of research for professionals, succinctly organizing the whole of chemistry. The one hundred or so elements listed in the table make up everything in the universe, from microscopic organisms to distant planets. Just how does the periodic table help us make sense of the world around us? Using vivid imagery, ingenious analogies, and liberal doses of humour P. W. Atkins answers this question. He shows us that the Periodic Kingdom is a systematic place. Detailing the geography, history and governing institutions of this imaginary landscape, he demonstrates how physical similarities can point to deeper affinities, and how the location of an element can be used to predict its properties. Here's an opportunity to discover a rich kingdom of the imagination kingdom of which our own world is a manifestation.

Dynamical processes in which many timescales coexist are called dispersive. The rate coefficients for dispersive processes depend on time. In the case of a chemical reaction, the time dependence of the rate coefficient, k(t), termed the specific reaction rate, is rationalized in the following way. Reactions by their very nature have to disturb reactivity distributions of the reactants in condensed media, as the more reactive species are the first ones to disappear from the system. The extent of this disturbance depends on the ratio of the rates of reactions to the rate of internal rearrangements (mixing) in the system restoring the initial distribution in reactivity of reactants. If the rates of chemical reactions exceed the rates of internal rearrangements, then the initial distributions in reactant reactivity are not preserved during the course of reactions and the specific reaction rates depend on time. Otherwise the extent of disturbance is negligible and classical kinetics, with a constant specific reaction rate, k, termed the reaction rate constant, may be valid as an approximation. In condensed media dispersive dynamical processes are endemic and this is the first monograph devoted to these processes.

This thesis describes improvements to and control of the electrical conductance in single-molecule junctions (SMJs), which have potential applications in molecular electronics, with a focus on the bonding between the metal and molecule. In order to improve the electrical conductance, the orbital of the molecule is directly bonded to the metal orbital, because anchoring groups, which were typically used in other studies to bind molecule with metal electrodes, became resistive spacers. Using this direct -binding, the author has successfully demonstrated highly conductive SMJs involving benzene, endohedral metallofullerene Ce@C82, and nitrogen. Subsequently, the author investigated control of the electrical conductance of SMJs using pyrazine. The nitrogen atom in the -conjugated system of pyrazine was expected to function as an anchoring point, and two bonding states were expected. One originates primarily from the orbital, while the other originates primarily from an n state of the nitrogen. Measurements of conductance and dI/dV spectra coupled with theoretical calculations revealed that the pyrazine SMJ has bistable conductance states, in which the pyrazine axis is either tilted or parallel with respect to the junction axis. The bistable states were switched by changing the gap size between the metal electrodes using an external force. Notably, it is difficult to change the electrical properties of bulk-state materials using mechanical force. The findings reveal that the electron transport properties of a SMJ can be controlled by designing a proper metal-molecule interface, which has considerable potential for molecular electronics. Moreover, this thesis will serve as a guideline for every step of SMJ research: design, fabrication, evaluation, and control.

Analyzes the extensive experimental and theoretical results on the phase composition, structure and properties of aluminium alloys containing scandium. The text studies the effects of scadium on these properties from a physico-chemical viewpoint. The authors present binary, ternary and more complex phase diagrams for these alloys and consider in detail recrystallization, superplastic behaviour and decomposition of supersaturated solid solutions and the effects of solidification conditions on phase equilibria. The microstructure stability for aluminium alloys containing scandium is estimated, based on a quantitative analysis of the alloys structure and properties. The realtion between the structure and properties of alloys with differing phase compositions, and tha acting hardening mechanisms are discussed. The authors also give some practical recommendations for alloying aluminium alloys with scandium. The experimental results presented in this book have provided a basis for the development of commercial aluminium alloys for a wide range of industrial applications.

This book describes in 2 parts experimental data with simple explanations (Part I) and itinerant electron theories (Part II) about magnetism and its related properties of 3d-intermetallic compounds. Unlike 3d-metal alloys and oxides, theoretical as well as experimental studies on 3d-intermetallic compounds such as 3d-pnictides and chalcogenides, on which we focus in this book, seem unfortunately delayed. The objective of this book is to motivate active studies in this ?eld in the future. We discuss in detail magnetic and related properties of the 3d-transition-metal pnictides and chalcogenides, which include the intermetallic compounds expressed as MX and M X, and their mixed compoundsM M X, MX X and M M X, 2 1?x x 1?y 2?x y x where M (M)isa3d element and X (X ) a pnicogen (P, As, Sb, and Bi) or a chalcogen (S, Se, and Te).

Few processes are as important for environmental geochemistry as the interplay between the oxidation and reduction of dissolved and solid species. The knowledge of the redox conditions is most important to predict the geochemical behaviour of a great number of components, the mobilities of which are directly or indirectly controlled by redox processes. The understanding of the chemical mechanisms responsible for the establishment of measurable potentials is the major key for the evaluation and sensitive interpretation of data. This book is suitable for advanced undergraduates as well as for all scientists dealing with the measurement and interpretation of redox conditions in the natural environment.

This book discusses essential stereochemical concepts associated with organic molecules (natural or synthetic), as reflected in the course of their many reactions, their mechanisms, their asymmetric synthesis, biosynthesis, and biological activities. This treatise provides useful insights and understanding of the chiral/achiral designations (nomenclatures), the stereochemical features, and related properties of the natural and synthetic products. Without having an adequate knowledge of stereochemical concepts, it will not be possible to understand and appreciate the stereochemistry of natural or synthetic products. Thus, essential static and dynamic aspects of stereochemistry with sufficient illustrative examples along with discussions are presented. The structure of the monograph allows for easy selection of separate topics for reading and teaching. This book will also provide an idea of basic stereochemical concepts, as applied to organic molecules in general as well as to organic ligands in coordination complexes, and will, therefore, be valuable resources to teachers and students of advanced undergraduates and post-graduates, researchers, and professionals.

Chemical kinetics aims to explain the factors governing the change with time of chemical systems. The results enable one to define optimum technico-economic condi tions (such as the choice of batch or continuous processes; of concentration, temperature, and pressure; of whether to use a catalyst) for the preparation of products, so that kinetics is intimately bound up with many processes of chemical industry (production, explosions, combustion, propulsion in air and in space). On another level, kinetic studies are indispensable for understanding reaction mechanisms, which implies a de tailed knowledge of the different chemical intermediates (possibly very transitory) of a chemical reaction. But in practice it is rarely possible to work with microscopic quantities of reagents and, with the exception of crossed molecular beams, all methods give only statistical results concerning a large number of molecules. Because of this restriction, it has not always been possible to establish conclusively a reaction mechanism, even for reactions ap parently simple. Numerous attempts have been made to calculate rate constants from the physical properties of the participating molecules; but the introduction of the 'time' factor into calculations of the distribution of energies of chemical processes makes this very difficult, so that the elucidation of mechanisms still depends almost entirely on experi mental studies. However, several theories have been elab orated which, in giving a more and more precise picture of the reaction process, have proved very fruitful, and have become indispensable in designing experiments."

This volume is a collection of the lectures presented at the NATO Advanced Study Institute "Interfacial Aspects of Phase Trans- formations", held in Erice (Sicily) in 198t.The Institute was the seventh course of the International School of Crystallography, es- tablished in the Center of Scientific Culture "Ettore Majorana" in 1974, with the guidance and inspiration of L. Riva di Sanseverino and A. Zichichi. The course organizers, R. Kern and myself, were advised and helped in developing the program, and in the choice of lecturers and participants, by R.F. Sekerka, F. Bedarida, J.L. Katz and J. G. Dash. Although the scope of the Institute (as reflected in the content of this book) might appear too wide, we believe that it responds to a real necessity. Both Surface Science and Crystal Growth (in- cluding problems of nucleation, thin films, recrystallization etc.) have developed to an unusual extent during the last few decades. Each of these two fields have benefited from the knowledge of the other; good examples are the progress in evaporation/condensation thermodynamics and kinetics of organized (sub-)monolayers, the de- velopement of new methods of preparing and characterizing atomical- ly smooth or controlled vicinal (stepped) surfaces, etc.

In response to the explosion of theories and experiments since the appearance of the first edition, the author has revised and expanded his basic text.

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.

In this thesis, Matthias Heydt applies digital in-line holography to achieve for the first time a complete three dimensional and real time motion analysis of Ulva zoospores, both in solution and in the vicinity of different surfaces. These results provide previously unknown information about the behavior and mechanism spores use to select a suitable site for settlement. This work gives deeper insight into biofouling algae and stimulates new design strategies for antifouling coatings. Furthermore, the tracking system developed during this research could be used as a new system for assessing the antifouling performance on different surfaces at very early points in time, allowing disentanglement of surface conditioning and interaction of spores with pristine chemistries.
