The current volume in the series "Vibrational Spectra and Structure" is a single topic volume on the vibrational spectra of molecules containing silicon in the solid state. "Molecular Approaches to Solids" has been treated by the workers in the Institute for Silicate Chemistry of the Russian Academy of Science in St. Petersburg for the past two decades. In the last 15 years, a number of publications have originated from the laboratory where quantum mechanical computations for suitably selected molecules have been utilized to explain the origins of some structure bonding interrelationships and silicates and to evaluate their force constants.

Since most of the developments in this area have been published in the Russian literature they remain relatively inaccessible to the Western scientists. This volume is a compilation of many of these publications and summarizes the essential conclusions of these studies.

Unfortunately, Professor Lazarev passed away after he had submitted the volume for publication.

by Professor D. E. Games, Mass Spectrometry Research Unit, University College of Swansea Sample preparation can be viewed as occupying a Cinderella role in analytical science. However, the quality of sample preparation plays a key role in high In the past decade, there has been quality analysis and deserves higher stature. considerable interest in the use of supercritical fluid extraction (SFE) as an alternative to conventional procedures for the preparation of samples for ana lysis. The driving force for this development is the need for automated, sim pler, faster, non-destructive and selective methods for extraction, preferably using non-toxic extraction media which are easily disposed of. Utilization of supercritical fluids for extraction fulfils these requirements because of their unique physical chemical properties and usually low toxicity. Selectivity can be achieved by suitable selection of pressure (density), temperature and modi fier conditions which enable solvating power to be varied. The high diffusivity of supercritical fluids provides rapid sample penetration and extraction. Use of fluids with low critical temperatures enables extraction to be conducted under mild thermal conditions ensuring that thermally labile compounds do not decompose. The technique can be used off-line, and the extracts analysed by appropriate techniques, or it can be used on-line, by coupling with a variety of chromatographic techniques. These can then, if necessary, be coupled fur ther with spectroscopic techniques, such as Fourier transform infrared, ultra violet or mass spectrometry, to provide specific identification or structural information."

Time-resolved fluorescence spectroscopy is widely used as a research tool in bioch- istry and biophysics. These uses of fluorescence have resulted in extensive knowledge of the structure and dynamics of biological macromolecules. This information has been gained by studies of phenomena that affect the excited state, such as the local environment, quenching processes, and energy transfer. Topics in Fluorescence Spectroscopy, Volume 4: Probe Design and Chemical Sensing reflects a new trend, which is the use of time-resolved fluorescence in analytical and clinical chemistry. These emerging applications of time-resolved fluorescence are the result of continued advances in laser detector and computer technology. For instance, pho- multiplier tubes (PMT) were previously bulky devices. Miniature PMTs are now available, and the performance of simpler detectors is continually improving. There is also considerable effort to develop fluorophores that can be excited with the red/ne- infrared (NIR) output of laser diodes. Using such probes, one can readily imagine small time-resolved fluorometers, even hand-held devices, being used fordoctor's office or home health care.

This book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8+ (Bi2212) and single-layer FeSe film grown on SrTiO3 (STO) substrate by means of angle-resolved photoemission spectroscopy (ARPES). It provides the first electronic evidence for the origin of the anomalous high-temperature superconductivity in single-layer FeSe grown on SrTiO3 substrate. Two coexisted sharp-mode couplings have been identified in superconducting Bi2212. The first ARPES study on single-layer FeSe/STO films has provided key insights into the electronic origin of superconductivity in this system. A phase diagram and electronic indication of high Tc and insulator to superconductor crossover have been established in the single-layer FeSe/STO films. Readers will find essential information on the techniques used and interesting physical phenomena observed by ARPES.

Over the last several years, the field of materials science has witnessed an explosion of new, advanced materials. They encompass many uses and include superconductors, alloys, glasses, and catalysts. Not only are there quite a number of new enhies into these generic classes of materials, but the materials themselves represent a wide array of physical forms as well. Bulk materials, for example, are being synthesized and applica tions found for them, while still other materials are being synthesized as thin films for yet still more new (and in some cases, as yet unknown) applications. The field continues to expand with (thankfully ) no end in sight as to the number of new possibilities. As work progresses in this area, there is an ever increasing demand for knowing not only what material is formed as an end product but also details of the route by which it is made. The knowledge of reaction mechanisms in their synthesis many times allows a researcher to tailor a preparative scheme to either arrive at the final product in a purer state or with a better yield. Also, a good fundamental experimental knowledge of impuri ties present in the final material helps the investigator get more insight into making it."

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Using a novel approach that combines high temporal resolution of the laser T-jump technique with unique sets of fluorescent probes, this study unveils previously unresolved DNA dynamics during search and recognition by an architectural DNA bending protein and two DNA damage recognition proteins. Many cellular processes involve special proteins that bind to specific DNA sites with high affinity. How these proteins recognize their sites while rapidly searching amidst ~3 billion nonspecific sites in genomic DNA remains an outstanding puzzle. Structural studies show that proteins severely deform DNA at specific sites and indicate that DNA deformability is a key factor in site-specific recognition. However, the dynamics of DNA deformations have been difficult to capture, thus obscuring our understanding of recognition mechanisms. The experiments presented in this thesis uncover, for the first time, rapid (~100-500 microseconds) DNA unwinding/bending attributed to nonspecific interrogation, prior to slower (~5-50 milliseconds) DNA kinking/bending/nucleotide-flipping during recognition. These results help illuminate how a searching protein interrogates DNA deformability and eventually "stumbles" upon its target site. Submillisecond interrogation may promote preferential stalling of the rapidly scanning protein at cognate sites, thus enabling site-recognition. Such multi-step search-interrogation-recognition processes through dynamic conformational changes may well be common to the recognition mechanisms for diverse DNA-binding proteins.

Gas chromatography mass spectrometry (GC-MS) has been the technique of choice of analytical scientists for many years. The latest developments in instrumentation, including tandem mass spectrometry (MS-MS) and time-of-flight (TOF) detectors, have opened up and broadened the scope of environmental analytical chemistry.

This book summarizes the major advances and relevant applications of GC-MS techniques over the last 10 years, with chapters by leading authors in the field of environmental chemistry. The authors are drawn from academia, industry and government.

The book is organized in three main parts. Part I covers applications of basic GC-MS to solve environmental-related problems. Part II focuses on GC-MS-MS instrumentation for the analyses of a broad range of analysis in environmental samples (pesticides, persistent organic pollutants, endocrine disruptors, etc.). Part III covers the use of more advanced GC-MS techniques using low- and high-resolution mass spectrometry for many applications related to the environment, food and industry.

In this book, the author theoretically studies two aspects of topological states. First, novel states arising from hybridizing surface states of topological insulators are theoretically introduced. As a remarkable example, the author shows the existence of gapless interface states at the interface between two different topological insulators, which belong to the same topological phase. While such interface states are usually gapped due to hybridization, the author proves that the interface states are in fact gapless when the two topological insulators have opposite chiralities. This is the first time that gapless topological novel interface states protected by mirror symmetry have been proposed. Second, the author studies the Weyl semimetal phase in thin topological insulators subjected to a magnetic field. This Weyl semimetal phase possesses edge states showing abnormal dispersion, which is not observed without mirror symmetry. The author explains that the edge states gain a finite velocity by a particular form of inversion symmetry breaking, which makes it possible to observe the phenomenon by means of electric conductivity.

This monograph solely investigates the Debye Screening Length (DSL) in semiconductors and their nano-structures. The materials considered are quantized structures of non-linear optical, III-V, II-VI, Ge, Te, Platinum Antimonide, stressed materials, Bismuth, GaP, Gallium Antimonide, II-V and Bismuth Telluride respectively. The DSL in opto-electronic materials and their quantum confined counterparts is studied in the presence of strong light waves and intense electric fields on the basis of newly formulated electron dispersion laws that control the studies of such quantum effect devices. The suggestions for the experimental determination of 2D and 3D DSL and the importance of measurement of band gap in optoelectronic materials under intense built-in electric field in nano devices and strong external photo excitation (for measuring photon induced physical properties) have also been discussed in this context. The influence of crossed electric and quantizing magnetic fields on the DSL and the DSL in heavily doped semiconductors and their nanostructures has been investigated. This monograph contains 150 open research problems which form the integral part of the text and are useful for both PhD students and researchers in the fields of solid-state sciences, materials science, nano-science and technology and allied fields in addition to the graduate courses in modern semiconductor nanostructures.

Bewitched is an odd word with which to begin a chemical textbook. Yet that is a fair description of how I reacted on first leaming of ion exchange and imagining what might be done with it. That initial fascination has not left me these many years later, and it has provided much ofthe motivation for writing this book. The perceived need for a text on the fundamentals of ion chromatography provided the rest. Many readers will have a general idea of what ion chromatography is and what it does. Briefly, for those who do not, it is an umbrella term for a variety of chromatographie methods for the rapid and sensitive analysis of mixtures of ionic species. It has become highly developed in the last decade, and while it is now routinely used for the determination of organic as weH as inorganic ions, its initial impact was greatest in the area of inorganic analysis. In the past the determination of inorganic ions, particularly anions, meant laborious, time-con suming, and often not very sensitive "wet chemieal" methods. In the last ten years that has changed radically as ion chromatography has supplanted these older methods."

Mass spectrometry (MS) offers unmatched capabilities for the detection, characterization, and identification of a broad range of analytes. Mass spectrometry imaging (MSI) integrates MS data with information on the spatial distributions of the analytes, further enhancing the applicability of MS. In Mass Spectrometry Imaging: Principles and Protocols, expert practitioners from academia, industry, and the clinic contribute cutting-edge protocols describing the application of MSI to investigations of analyte localization in a variety of specimens, from microorganisms to plant and animal tissues. Divided into three sections, this volume presents the principles of MS, current and future trends of MSI, and qualitative and quantitative protocols to measure and identify endogenous metabolites and xenobiotics. An array of MSI approaches and technologies for characterizing peptide and protein distributions are described in detail. Written in the highly successful Methods in Molecular Biology (TM) series format, protocol chapters include introductions to their respective topics, lists of the necessary materials and reagents, and step-by-step, readily reproducible laboratory procedures. Also included are notes providing tips to avoid experimental pitfalls and helpful suggestions for method troubleshooting. Comprehensive and up-to-date, Mass Spectrometry Imaging: Principles and Protocols is written for scientists, biological and chemical engineers, and clinicians who are interested in applying MSI in their work and those who would benefit from having detailed experimental guidelines available in a single, convenient source.

The book begins by covering the basic principles of both gas chromatography (GC) and mass spectrometry (MS) to the extent necessary to understand and deal with the data generated in a GC-MS analysis. The focus then turns to the particular requirements created by a direct combination of these two techniques into a single instrumentation system. The data generated and their use are covered in detail. The role of the computer and its specific software receives special attention, especially in the matter of compound identification via mass spectral search techniques. GC-MS-computer instrumentation has reached such a plateau of excellence today that the present commercial systems will not be obsolete for a long time to come. Therefore, a detailed description of these systems is not only informative but is also pertinent to the subject matter of this book. Finally, representative applications and results obtained with GC-MS-computer techniques are presented and chosen in such a way as to permit extrapolation of specific applications to similar problems encountered by the reader. To aid the reader in mastering the subject matter and increase understanding, interpretation problems and suggested readings are included. The format is instructional, informative and application-oriented with material presented in such a way as to be useful to a broad spectrum of people.
The book serves as a text in its own right.
The software package Gas Chromatography-Mass Spectrometry: A Knowledge Base, by F.A. Settle, Jr. and M.A. Pleva provides rapid access to a wealth of current information in the GC-MS field.

The development of linear-scaling density functional theory (LS-DFT) has made ab initio calculations on systems containing thousands of atoms possible. These systems range from nanostructures to biomolecules. These methods rely on the use of localized basis sets, which are optimised for the representation of occupied Kohn-Sham states but do not guarantee an accurate representation of the unoccupied states. This is problematic if one wishes to combine the power of LS-DFT with that of theoretical spectroscopy, which provides a direct link between simulation and experiment. In this work a new method is presented for optimizing localized functions to accurately represent the unoccupied states, thus allowing theoretical spectroscopy of large systems. Results are presented for optical absorption spectra calculated using the ONETEP code, but the method is equally applicable to other spectroscopies and LS formulations. Other topics covered include a study of some simple one dimensional basis sets and the presentation of two methods for band structure calculation using localized basis sets, both of which have important implications for the use of localized basis sets within LS-DFT.
