Volume 4: Organic and Organometallic Compounds

This volume presents a cross section of applications in organic and organometallic chemistry in two parts. Chapters 1 to 6 are devoted to the fundamentals whereas chapters 7 and 8 cover applications to organic and organometallic compounds, either available as pure compounds or present in complex mixtures.

Chapter 1 describes the theory for organic mass spectrometry, building on and complementing material in Volume 1. The themes for Chapter 2 are the structures and properties of gas-phase ions of conventional, distonic, and non-covalent complexes. Chapter 3 covers methodology used in study of gas-phase ions. Chapters 4 and 5 turn to mechanisms of both unimolecular and bimolecular reactions of ions and include topics in stereochemistry and radical chemistry. Chapter 6 contains a number of articles on the formation and reactivity of metal ion complexes and organometallic cations and anions, drawing connections with molecular recognition, catalysis and organic synthesis.

Chapter 7 deals with the structure determination of organic compounds, including chiral compounds and natural products. In chapter 8 are contributions that provide illustrative examples of the determination of organic compounds present at low levels in complex samples that originate from various natural and biological sources. Included is an article on the determination of explosives.
* Cross section of the field of Organic and Organometallic MS

This book starts with the most elementary ideas of molecular orbital theory and leads the reader progressively to an understanding of the electronic structure, geometry and, in some cases, reactivity of transition metal complexes. The qualitative orbital approach, based on simple notions such as symmetry, overlap and electronegativity, is the focus of the presentation and a substantial part of the book is associated with the mechanics of the assembly of molecular orbital diagrams. The first chapter recalls the basis for electron counting in transition metal complexes. The main ligand fields (octahedral, square planar, tetrahedral, etc.) are studied in the second chapter (sigma interactions) and the structure of the "d block" is used to trace the relationships between the electronic structure and the geometry of the complexes. The third chapter studies the change in analysis when the ligands have pi-type interactions with the metal. All these ideas are then used in the fourth chapter to study a series of selected applications of varying complexity (structure, reactivity). The fifth chapter deals with the "isolobal analogy" which points out the resemblance between the molecular orbitals of inorganic and organic species and provides a bridge between these two subfields of chemistry. The last chapter is devoted to a presentation of basic Group Theory with applications to some of the complexes studied in the earlier chapters.

As part of a collaboration between two different groups in chemistry and biochemistry, Thom Sharp presents here his thesis work on the development of new methods for cryoelectron microscopy. Throughout his Ph.D., Thom had to master a whole range of techniques including modelling, molecular biology and microscopy. Using these skills to tackle an outstanding problem, the pursuit of high-resolution structures of peptide-based materials, Thom highlights in this thesis his newly developed methods for analysing and processing this particular type of electron microscopy data. This thesis gives the first molecular description of a de-novo designed peptide-based material. In general, this research will have a huge impact on the peptide assembly field, and also in electron microscopy as it introduces new methods and approaches, all of which are Thom's inventions and are described in this thesis.

Most chemists, whether they are biochemists, organic, analytical, pharmaceutical or clinical chemists and many pharmacists and biologists need to perform chemical analysis. Consequently, they are not only confronted with carrying out the actual analysis, but also with problems such as method selection, experimental design, optimization, calibration, data acquisition and handling, and statistics in order to obtain maximum relevant chemical information. In other words: they are confronted with chemometrics. This book on chemometrics, written by some of the leaders in the field, aims to provide a thorough, up-to-date introduction to this subject. The reader is given the opportunity to acquaint himself with the tools used in this discipline and the way in which they are applied. Some practical examples are given and the reader is shown how to select the appropriate tools in a given situation.

As such the book provides the means to approach and solve analytical problems strategically and systematically, without the need for the reader to become a fully-fledged chemometrician. The authors' aim was to write a tutorial book which would be useful to readers at every level in this field.

Interdisciplinary knowledge is becoming more and more important to the modern scientist. This invaluable textbook covers bioanalytical chemistry (mainly the analysis of proteins and DNA) and explains everything for the nonbiologist. Electrophoresis, mass spectrometry, biosensors, bioassays, DNA and protein sequencing are not necessarily all included in conventional analytical chemistry textbooks. The book describes the basic principles and the applications of instrumental and molecular methods. It is particularly useful to chemistry and engineering students who already have some basic knowledge about analytical chemistry.

The book starts with an introduction on silicon isotopes and related analytical methods, and explains the mechanisms of silicon isotope fractionation. Silicon isotope distributions in lithosphere, hydrosphere and biosphere are shown based on results from field studies, and silicon isotope relevance for applications are presented.

Springer Handbook of Enzymes provides data on enzymes sufficiently well characterized. It offers concise and complete descriptions of some 5,000 enzymes and their application areas. Data sheets are arranged in their EC-Number sequence and the volumes themselves are arranged according to enzyme classes.

This new, second edition reflects considerable progress in enzymology: many enzymes are newly classified or reclassified. Each entry is correlated with references and one or more source organisms. New datafields are created: application and engineering (for the properties of enzymes where the sequence has been changed). The total amount of material contained in the Handbook has more than doubled so that the complete second edition consists of 39 volumes as well as a Synonym Index. In addition, starting in 2009, all newly classified enzymes are treated in Supplement Volumes.

Springer Handbook of Enzymes is an ideal source of information for researchers in biochemistry, biotechnology, organic and analytical chemistry, and food sciences, as well as for medicinal applications.

Surface plasmon resonance (SPR) has evolved into an exciting technique in biomolecular interaction analysis. The development of commercial SPR instruments has made the te- nique available to a wide scienti?c audience, and the number of publications in which the use of SPR is described is rapidly increasing. SPR is in use for many purposes from food quality control to the study of nanoparticles. Much research is now focused on devel- ing new SPR-related applications, e.g., SPR imaging, SPR arrays, SPR ?uorescence, and combinations of SPR with mass spectrometry and with electrochemistry. Biomolecular interaction analysis is at the core of many research projects. In principle, the setup of an SPR experiment is simple: There is a sensor surface to which one of the interacting partners (the ligand) is immobilized; the other partner (the analyte) is added in a ?ow or cell-like compartment. The binding phenomenon is monitored in real time as a change in SPR angle. An important issue is the choice of surface and the immobilization strategy. With SPR, it is possible to mimic the biological environment which is relevant for an interaction. For interactions in a water environment, sensor surfaces with hydrogels are available. Many biomolecular interactions take place in a membrane environment. For this, commercial sensor surfaces are available, or surfaces can be tailor-made. This volume contains several examples of building up of lipophilic surfaces. Nature abundantly makes use of multivalent interactions; multivalency can be mimicked on a sensor surface with immobilized ligands.

Tian Lu's dissertation describes major advances in ultrathin-layer chromatography (UTLC), liquid chromatography and surface-assisted laser desorption ionization (SALDI), and matrix-enhanced SALDI (ME-SALDI) mass spectrometry. Lu describes the fabrication of electrospun polyvinyl alcohol (PVA) UTLC plates using an in-situ crosslinking electrospinning technique. The author improved the efficiency of PVA plates greatly compared to the efficiency of silica HPTLC plates. Also highlighted in this thesis is an edge-plane based ordered-carbon surface that provides unique selectivity in liquid chromatography. Further developments include polar analytes, such as amino acids, nucleotides and nucleosides which can be well-retained and separated in the edge-plane ordered-carbon stationary phase. Also, the author studied and detected mass spectra of organic polymers as high as 900,000 Da, the highest molecular weight that has been studied by SALDI to date using the carbon nanofibrous substrate. This thesis has led to a number of publications in high-impact journals.

Crown ethers and calixarenes - the latter ones discovered only recently - are powerful complexing ligands for alkali and alkaline earth metals. This led to their immediate and wide-spread application in biosciences. This book is exclusively devoted to the very promising applications of these compounds in analytical chemistry. It focusses on solvent extraction, chromatography, spectroscopy and electroanalytical methods.

Scientists from many disciplines require making observations which are dependent upon the behavior of compounds in solution. This ranges from areas in geography, such as oceanography, to areas in chemistry, such as chromatography, to areas in biology, such as pharmacology. Historically, information would be obtained by observing a response for a given set of conditions and then the conditions would be changed and a new response obtained. In this approach there would be little effort made to actually understand how a compound was behaving in solution but rather just the response was noted. Understanding the behavior of compounds in solution is critical to understanding their behavior in biological systems. This has become increasingly important during the last twenty years as an understanding of the biochemistry related to human illness has become better understood. The development of the pharmaceutical industry and the need to rapidly screen large numbers of compounds has made scientists in the area of drug development aware that the pharmacological activity of compounds can be predicted by knowing their solution physical chemical properties. This is not to say that a specific drug-active site interaction can be predicted but rather a prediction can be made whether or not a compound will be absorbed, transported, or distributed within a physiological system in such a way that an interaction can occur.

This book is a manual of measurement of colloids and interfaces designed especially for new researchers who have just begun research on these topics. The book is written by active researchers in the field of colloids and interfacial chemistry, based on the practical experience of the authors. In each chapter, the key points of measurement, how to analyze data correctly, points to be careful about, and merits of a particular method are concisely explained from the point of view of the readers. Not only in industries such as cosmetics and pharmaceuticals but also in academic studies of nanotechnology, correct understanding of colloid and interface phenomena is vital because the properties of these items, however small, are affected by the nature of interfaces. This book will be particularly useful for researchers who are not yet fully confident of the measurement techniques that are clearly explained here.

This book, "Integrated Chemical Microsensor Systems in CMOS Technology," provides a comprehensive treatment of the highly interdisciplinary field of CMOS chemical microsensor systems. It is targeted at students, scientists and engineers who are interested in gaining an introduction to the field of chemical sensing since all the necessary fundamental knowledge is included. However, as it provides detailed information on all important issues related to the realization of chemical microsensors in CMOS technology, it also addresses experts well familiar with the field.

After a brief introduction, the fundamentals of chemical sensing are presented. Fabrication and processing steps that are commonly used in the semiconductor industry are then detailed followed by a short description of the microfabrication techniques, and of the CMOS substrate and materials. Thereafter, a comprehensive overview of semiconductor-based and CMOS-based transducer structures for chemical sensors is given. CMOS-technology is then introduced as platform technology, which enables the integration of these microtransducers with the necessary driving and signal conditioning circuitry on the same chip. In a next section, the development of monolithic multisensor arrays and fully developed microsystems with on-chip sensor control and standard interfaces is described. A short section on packaging shows that techniques from the semiconductor industry can be applied to chemical microsensor packaging. The book concludes with a brief outlook on future developments, such as the realization of more complex integrated microsensor systems and methods to interface biological materials, such as cells, with CMOS microelectronics.

Electrochemistry plays an important role in preserving our cultural heritage. For the first time this has been documented in the present volume. Coverage includes both electrochemical processes such as corrosion and electroanalytical techniques allowing to analyse micro- and nanosamples from works of art or archaeological finds. While this volume is primarily aimed at electrochemists and analytical chemists, it also contains relevant information for conservators, restorers, and archaeologists.

This is the first book to show how to apply the principles of quality assurance to the identification of analytes (qualitative chemical analysis). After presenting the principles of identification and metrological basics, the author focuses on the reliability and the errors of chemical identification. This is then applied to practical examples such as EPA methods, EU, FDA, or WADA regulations. Two whole chapters are devoted to the analysis of unknowns and identification of samples such as foodstuffs or oil pollutions. Essential reading for researchers and professionals dealing with the identification of chemical compounds and the reliability of chemical analysis.
