RELATIVISTIC EFFECTS IN CHEMISTRY

This century's most famous equation, Einstein's special theory of relativity, transformed our comprehension of the nature of time and matter. Today, making use of the theory in a relativistic analysis of heavy molecules, that is, computing the properties and nature of electrons, is the work of chemists intent on exploring the mysteries of minute particles.

The first work of its kind, Relativistic Effects in Chemistry details the computational and analytical methods used in studying the relativistic effects in chemical bonding as well as the spectroscopic properties of molecules containing very heavy atoms. The second of two independent volumes, Part B: Applications contains specific experimental and theoretical results on the electronic states of molecules containing very heavy atoms as well as their spectroscopic properties and electronic structures. The first one-volume catalog of comprehensive computational results, Part B details:

• the relativistic effects on the electronic structure of transition metal clusters, such as the Cu, Ag, and Au triad
• the electronic structure of open-shell transition metal clusters such as Rh3 and Ir3
• the electronic and spectroscopic properties of heteronuclear diatomics of main group p-block elements from Ga to Po, especially the diatomic hydrides, halides, and chalconides
• the clusters of the very heavy main group p-block elements from Ga to Po
• the relativistic effects on molecules containing lanthanide and actinide atoms, including metals inside fullerenes.

An extraordinary new examination of Periodic Table elements, Part B of Relativistic Effects in Chemistry is also evidence of the enduring influence of Einstein's revolutionary theory.

Shale oil and gas have altered the energy landscape, possibly permanently. They burst upon the fossil energy scene with a suddenness that initially defied prediction. Even the political balance of the world has changed. But, with the methods employed, the vast majority of the oil and gas remains in the ground. At the same time, serious environmental impact issues have been raised. A new volume in the Emerging Issues in Analytical Chemistry series, Sustainable Shale Oil and Gas: Analytical Chemistry, Geochemistry, and Biochemistry Methods was written on the premise that analytical methods to inform these areas were wanting. While not attempting to be comprehensive, it describes important analytical methods, some still in development. These methods are underpinned primarily by chemistry, but geochemistry and even biochemistry play significant roles. The book has a solutions flavor; problems are posed together with approaches to ameliorate them.

The most up to date book on the topic Suitable for use as a textbook Contains a systematic description of each technique it describes Covers a broad readership, including nanotechnology, biotechnology, biophysics, analytical chemistry, and chemical biology Provides a highly simplified tutorial protocol at the end of each chapter to help readers obtain hands-on experience

This book addresses the basic understanding of food contaminants and their sources, followed by the techniques to measure food safety and quality. It is divided into four parts: Part A - sources of contaminants in foods, their associated health risks, and integrated management and alternative options to minimize contaminants; Part B - Technological assessment of conventional methods and selected advanced methods for the detection, identification and enumeration of microbial contaminates; Part C - Technological assessment of different chemical measurements techniques; and Part D - Technological assessment of different instrumental techniques to assess sensory properties of foods. Food safety is a growing concern due to the increase in food-borne illnesses caused by food adulteration, excessive use of pesticides, use of chemical preservatives and artificial fruit ripening agents, microbial contaminations, and improper food handling. Chemical contaminants in food could be transferred from environmental or agrochemical sources, personal care products, and other by-products of water disinfects. In addition, microbial food safety can be threatened due to the presence of many pathogens, such as Salmonella, Escherichia coli, Clostridium botulinum, Staphylococcus aureus, and Listeria monocytogenes in foods. Globally, strict regulations are imposed to limit the potential contaminants in foods. Development of accurate, rapid, and inexpensive approaches to test food contamination and adulteration would be highly valued to ensure global food safety. There are existing processes to ensure safety of food products from chemical and microbial contaminants. Apart from the existing measurement technologies, varieties of new techniques are also being emerged and these could be potential to ensure food safety and quality. In addition to chemical and microbial properties, sensory properties such as texture, mouth feel, flavor, and taste, are among the most important attributes of food products to ensure their acceptability by consumers. Two approaches are available to evaluate sensory properties of food products, namely subjective and objective analyses. The responses are perceived by all five senses: smell, taste, sight, touch, and hearing. The approach used in sensory evaluation varies depending on the types of foods and the ultimate goal of the testing. Sensory attributes are the most important quality parameters after ensuring the safety of foods.

Food contains various compounds and many technologies exist to analyze those molecules of interest. However, the analysis of the spatial distribution of those compounds using conventional technology, such as liquid chromatography-mass spectrometry or gas chromatography-mass spectrometry is difficult. Mass spectrometry imaging (MSI) is a mass spectrometry technique to visualize the spatial distribution of molecules, as biomarkers, metabolites, peptides or proteins by their molecular masses. Despite the fact that MSI has been generally considered a qualitative method, the signal generated by this technique is proportional to the relative abundance of the analyte and so quantification is possible. Mass Spectrometry Imaging in Food Analysis, a volume in the Food Analysis and Properties Series, explains how the novel use of matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) will be an ideal complementary approach. MALDI-MSI is a two-dimensional MALDI-MS technology that can detect compounds in a tissue section without extraction, purification, separation, or labeling. It can be used to visualize the spatial distribution of biomolecules in foods. Features: Explains the novel use of matrix-assisted laser desorption/ionization mass spectrometry imaging in food analysis Describes how MALDI-MSI will be a useful technique for optical quality assurance. Shows how MALDI-MSI detects food contaminants and residues Covers the historical development of the technology While there are a multitude of books on mass spectrometry, none focus on food applications and thus this book is ideally suited to food scientists, food industry personnel engaged in product development, research institutions, and universities active in food analysis or chemical analysis.

This book suggests a new common approach to the study of resonance energy transport based on the recently developed concept of Limiting Phase Trajectories (LPTs), presenting applications of the approach to significant nonlinear problems from different fields of physics and mechanics. In order to highlight the novelty and perspectives of the developed approach, it places the LPT concept in the context of dynamical phenomena related to the energy transfer problems and applies the theory to numerous problems of practical importance. This approach leads to the conclusion that strongly nonstationary resonance processes in nonlinear oscillator arrays and nanostructures are characterized either by maximum possible energy exchange between the clusters of oscillators (coherence domains) or by maximum energy transfer from an external source of energy to the chain. The trajectories corresponding to these processes are referred to as LPTs. The development and the use of the LPTs concept a re motivated by the fact that non-stationary processes in a broad variety of finite-dimensional physical models are beyond the well-known paradigm of nonlinear normal modes (NNMs), which is fully justified either for stationary processes or for nonstationary non-resonance processes described exactly or approximately by the combinations of the non-resonant normal modes. Thus, the role of LPTs in understanding and analyzing of intense resonance energy transfer is similar to the role of NNMs for the stationary processes. The book is a valuable resource for engineers needing to deal effectively with the problems arising in the fields of mechanical and physical applications, when the natural physical model is quite complicated. At the same time, the mathematical analysis means that it is of interest to researchers working on the theory and numerical investigation of nonlinear oscillations.

Polycyclic aromatic hydrocarbons (PAHs) are the first type of chemicals that were ever discovered to cause cancer in humans. They are found in cigarette smoke, in barbecued and smoked foods, in automobile and Diesel engine exhaust, fireplace smoke, and many other common things that people are exposed to. Analyzing for PAHs in the environment is important in identifying potential sources of cancer exposure and eliminating these as risks. The smaller PAHs, those of lower than 300 molecular weight, have been the most studied and have also been covered in several books. No books have dealt with the analysis of the larger PAHs. These compounds are not only important for the health concerns, but they are also of current technological and scientific interest.

"Hills is probably the best person I can think of to write this book. He has the deepest background combined with considerable experience in solving problems with food." —R. G. Bryant, University of Virginia.

Food scientists have many excellent tools at their disposal with which to study food at both the micro- and macrostructural levels. But, when it comes to analyzing dynamic structural changes in food during processing and storage, none can compare with magnetic resonance imaging (MRI). Still a very young approach, MRI food imaging has contributed greatly to recent advances in food science, and promises to yield much more valuable information in the years ahead. Written by a leading pioneer in the field, Magnetic Resonance Imaging in Food Science covers the latest in MRI food imaging theory and practice.

Written primarily for food scientists and engineers, the book offers a practical, unified approach to the subject. Material is organized in three main parts corresponding to the distances of scale probed by MRI studies—namely, the macroscopic, microscopic, and macromolecular. Throughout, the emphasis is on ways in which studies of food undergoing processes can be modeled using the equations of heat, mass, and momentum transport, and how those models can be used in process design optimization programs.

Magnetic Resonance Imaging in Food Science provides researchers with the most up-to-date, detailed coverage of:

• Traditional and cutting-edge MRI food imaging techniques and technologies, including STRAFI, gradient-echo imaging, and functional imaging
• Whole plant functional imaging, flow imaging and rheology, and other specialized MRI applications

Applications of Time-of-Flight and Orbitrap Mass Spectrometry in Environmental, Food, Doping, and Forensic Analysis deals with the use of high-resolution mass spectrometry (MS) in the analysis of small organic molecules. Over the past few years, time-of-flight (ToF) and Orbitrap MS have both experienced tremendous growth in a great number of analytical sectors and are now well established in many laboratories where high requirements are placed on analytical performance. This book gives a head-to-head comparison of these two technologies that compete directly with each other. As users with hands-on experience in both techniques, the authors provide a balanced description of the strengths and weaknesses of both techniques. In the vast majority of cases, ToF-MS and Orbitrap-MS have been used for qualitative purposes, mainly identification of discrete molecular entities such as drug metabolites or transformation products of environmental contaminants. This paradigm is now changing as quantitative capabilities are increasingly being explored, as are non-target approaches for unbiased broad-scope screening. In view of the continuous innovation of high-resolution MS instrument manufacturers in designing and developing more powerful machines, technological advances in both hardware and software are considerable, with many novel applications. This book summarizes and analyzes these trends. The compilation of selected examples from diverse analytical fields will allow the readers to discover not only the potential of high-resolution MS in their sector, but also shows advances in other fields that rely on hi-res MS.

This thesis contains three breakthrough results in condensed matter physics. Firstly, broken reflection symmetry in the hidden-order phase of the heavy-fermion material URu2Si2 is observed for the first time. This represents a significant advance in the understanding of this enigmatic material which has long intrigued the condensed matter community due to its emergent long range order exhibited at low temperatures (the so-called "hidden order"). Secondly and thirdly, a novel collective mode (the chiral spin wave) and a novel composite particle (the chiral exciton) are discovered in the three dimensional topological insulator Bi2Se3. This opens up new avenues of possibility for the use of topological insulators in photonic, optoelectronic, and spintronic devices. These discoveries are facilitated by using low-temperature polarized Raman spectroscopy as a tool for identifying optically excited collective modes in strongly correlated electron systems and three-dimensional topological insulators.

Regarded as a seminal work in chemometrics, Information Theory as Applied to Chemical Analysis by Karel Eckscklager and Vladimir Stepanek shed light on the importance of information theory, stressing that the very mechanisms of information gathering are key to the quality of the analytical data collected. Continuing that examination, this new volume, Information Theory in Analytical Chemistry, looks at the practical applications of information theory, especially as a tool for optimizing chemical analysis. Complete with up-to-date examples from diverse areas such as toxicology, environmental science, and metallurgy, the book provides a workable framework for developing, optimizing, and assessing analytical procedures. Layer by layer, the analytical process is dismantled - and reassembled - so the reader develops a genuine, practice-oriented grasp of just how information theory shapes the chemical analysis process. Beginning with the fundamentals of information theory and analytical chemistry, the book then considers the systemic nature of chemical analysis, examining each of its facets: identification of components, trace analysis, qualitative analysis, quantitative analysis, multicomponent analysis, microanalysis, and surface or structure analysis. Up-to-date, detailed discussion includes: identification of an individual component or a group of compounds; effect of a priori knowledge of the sample on the information gain of the result; importance of calibration methods and reference material and their net effect on the precision and accuracy of results; choice of the optimum analytical method, criteria of selection; quality control, external and internal quality assurance; chemicalhomogeneity testing. Particularly important in trace and multivariate analysis, the book also sheds light on the information content inherent in analytical instrumentation, contrasting it with the true information gains of the analysis. Essential to understanding the individual steps of analytical process, this distinction allows for better evaluation and optimization of each step, including calibration and signal processing. The book also assesses the information contribution of key chemometric methods, such as cluster analysis, pattern recognition, and factorial data analysis, useful in multivariate or multicomponent analysis. This discussion, in turn, provides insight into the true character of multivariate data analysis, revealing it as not simply a string of single-component analyses done simultaneously, but rather a fragile, potentially bias-ridden mechanism with unique interpretive potential of its own. Complete with tables, diagrams, and examples, Information Theory in Analytical Chemistry is a practical handbook of enhanced analytical techniques that can sharply improve the quality of data collection as well as a user's understanding of the significance of information theory in each step of the entire chemical analysis process.
