The history of the application of semiconductors for controlling currents goes back all the way to 1926, in which Julius Lilienfeld led a patent for a "Method and apparatus for controlling electric currents" [1], which is considered the rst work on metal/semiconductor eld-effect transistors. More well-known is the work of William Shockley, John Bardeen and Walter Brattain in the 1940s [2, 3], after which the development of semiconductor devices commenced. In 1958, independent work from Jack Kilby and Robert Noyce ledto the invention of integrated circuits. A few milestones in IC design are the rst monolithic operational ampli er in 1963 (Fairchild?A702, Bob Widlar) and the rst o- chip 4-bit microprocessor in 1971 (Intel 4004). Ever since the start of the semiconductor history, integration plays an imp- tant role: starting from single devices, ICs with basic functions were developed (e. g. opamps, logic gates), followed by ICs that integrate larger parts of a s- tem (e. g. microprocessors, radio tuners, audio ampli ers). Following this trend of system integration, this eventually leads to the integration of analog and d- ital components in one chip, resulting in mixed-signal ICs: digital components are required because signal processing is preferably done in the digital - main; analog components are required because physical signals are analog by nature. Mixed-signal ICs are already widespread in many applications (e. g. - dio, video); for the future, it is expected that this trend will continue, leading to a larger scale of integration.

Planar Chromatography-Mass Spectrometry focuses on a relatively new approach to chemical analysis in general, and to separation science in particular. It is the first book to systemically cover the theoretical background, techniques, instrumentation, and practical applications of planar chromatography-mass spectrometry as a hyphenated tool of analytical chemistry. It also examines the high and as-yet unexploited potential of planar chromatography-mass spectrometry for analytical use in scientific investigations. This book overviews the combination of planar chromatography, a relatively simple and cost-effective separation step for determining complex mixtures of compounds, with mass spectrometry, an efficient, highly instrumental, and relatively expensive technique that enables rapid identification of separated chemical species. It covers electrophoretic-mass spectrometry methods and applications, which are considered planar chromatographic techniques and are increasingly being exploited in proteomic and molecular biology studies as well as for medical diagnostic purposes. It also provides a selection of applications, such as drug control and forensic and food analysis, including more difficult substances such as carbohydrates and lipids. The book advocates growth in using planar chromatography-mass spectrometry in laboratories that have appropriate equipment but have not yet employed the techniques in combination. It also describes the use of a relatively inexpensive commercial system that can be adopted by laboratories currently working without the coupled methodology. Aiming to improve power and efficiency when other analytical methods are inadequate, Planar Chromatography-Mass Spectrometry encourages separation science practitioners in academia and industry to combine the two methods for enhanced results.

The isolation and structural characterization of substances present at very low concentrations, as is necessary to satisfy regulatory requirements for pharmaceutical drug degradants and impurities, can present scientific challenges. The coupling of HPLC with NMR spectroscopy has been at the forefront of cutting-edge technologies to address these issues. LC-NMR: Expanding the Limits of Structure Elucidation presents a comprehensive overview of key concepts in HPLC and NMR that are required to achieve definitive structure elucidation with very low levels of analytes. Because skill sets from both of these highly established disciplines are involved in LC-NMR, the author provides introductory background to facilitate readers' proficiency in both areas, including an entire chapter on NMR theory. The much-anticipated second edition provides guidance in setting up LC-NMR systems, discussion of LC methods that are compatible with NMR, and an update on recent hardware and software advances for system performance, such as improvements in magnet design, probe technology, and solvent suppression techniques that enable unprecedented mass sensitivity in NMR. This edition features methods to quantify concentration and assess purity of isolated metabolites on the micro scale and incorporates computational approaches to accelerate the structure elucidation process. The author also includes implementation and application of qNMR and automated and practical use of computational chemistry combined with QM and DFT to predict highly accurate NMR chemical shifts. The text focuses on current developments in chromatographic-NMR integration, with particular emphasis on utility in the pharmaceutical industry. Applications include trace analysis, analysis of mixtures, and structural characterization of degradation products, impurities, metabolites, peptides, and more. The text discusses novel uses and emerging technologies that challenge detection limits as well future directions for this important technique. This book is a practical primary resource for NMR structure determination-including theory and application-that guides the reader through the steps required for isolation and NMR structure elucidation on the micro scale.

This thesis provides the first comprehensive theoretical overview of the electronic and optical properties of two dimensional (2D) Indium Selenide: atomically thin films of InSe ranging from monolayers to few layers in thickness. The thesis shows how the electronic propertes of 2D InSe vary significantly with film thickness, changing from a weakly indirect semiconductor for the monolayer to a direct gap material in the bulk form, with a strong band gap variation with film thickness predicted and recently observed in optical experiments. The proposed theory is based on a specially designed hybrid k.p tight-binding model approach (HkpTB), which uses an intralayer k.p Hamiltonian to describe the InSe monolayer, and tight-binding-like interlayer hopping. Electronic and optical absorption spectra are determined, and a detailed description of subbands of electrons in few-layer films and the influence of spin-orbit coupling is provided. The author shows that the principal optical excitations of InSe films with the thickness from 1 to 15 layers broadly cover the visible spectrum, with the possibility of extending optical functionality into the infrared and THz range using intersubband transitions.

The emerging field of lipidomics has been made possible because of advances in mass spectrometry, and in particular tandem mass spectrometry of lipid ions generated by electrospray ionization. The ability to carry out basic biochemical studies of lipids using electrospray ionization is predicated upon understanding the behaviour of lipid derived ions following collision induced decomposition and mechanisms of product ion formation. During the past 20 years, a wealth of information has been generated about lipid molecules that are now analysed by mass spectrometry, however there is no central source where one can obtain basic information about how these very diverse biomolecules behave following collisional activation. This book brings together, in one volume, this information so that investigators considering using tandem mass spectrometry to structurally characterize lipids or to quantitate their occurrence in a biological matrix, will have a convenient source to review mechanism of decomposition reactions related to the diversity of lipid structures. A separate chapter is devoted to each of seven major lipid classes including fatty acids, eicosanoids and bioactive lipid mediators, fatty acyl esters and amides, glycerol esters, glycerophospholipids, sphingolipids, and steroids. Mechanistic details are provided for understanding the pathways of formation of major product ions and ions used for structural characterization. In most cases specific ancillary information has been critical to understand the pathways, including isotope labeling and high resolution analysis of precursor and product ions. For a few specific examples such data is missing and pathways are proposed as a means to initiate further mass spectral experiments to prove or disprove pathway hypotheses. While this work largely centres on the lipid biochemistry of animal (mammalian) systems, general principles can be taken from the specific examples and applied to lipid biochemistry found in plants, fungi, prokaryotes and archeal organisms.

This volume presents the recent progress and perspective in multi-photon processes and spectroscopy of atoms, ions, molecules and solids.

This book examines Thomas Hardy's representations of the road and the ways the archaeological and historical record of roads inform his work. Through an analysis of the uneven and often competing road signs found within three of his major novels - The Return of the Native, Tess of the D'Urbervilles, and Jude the Obscure - and by mapping the road travels of his protagonists, this book argues that the road as represented by Hardy provides a palimpsest that critiques the Victorian construction of social and sexual identities. Balancing modern exigencies with mythic possibilities, Hardy's fictive roads exist as contested spaces that channel desire for middle-class assimilation even as they provide the means both to reinforce and to resist conformity to hegemonic authority.

Oxygen-Ozone therapy is a complementary approach less known than homeopathy and acupuncture because it has come of age only three decades ago. This book clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classical biochemistry, physiological and pharmacological knowledge. Ozone is an oxidizing molecule, a sort of super active oxygen, which, by reacting with blood components generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes and cancer. Moreover, by inducing nitric oxide synthase, ozone therapy may mobilize endogenous stem cells, which will promote regeneration of ischemic tissues. The description of these phenomena offers the first comprehensive picture for understanding how ozone works and why. When properly used as a real drug within therapeutic range, ozone therapy does not only does not procure adverse effects but yields a feeling of wellness. Half the book describes the value of ozone treatment in several diseases, particularly cutanious infection and vascular diseases where ozone really behaves as a "wonder drug." The book has been written for clinical researchers, physicians and ozone therapists, but also for the layman or the patient interested in this therapy.

In this book, density functional theory (DFT) is introduced within the overall context of quantum chemistry. DFT has become the most frequently used theory in quantum chemistry calculations. However, thus far, there has been no book on the fundamentals of DFT that uses the terminology and methodology of quantum chemistry, which is familiar to many chemists, including experimentalists. This book first reviews the basic concepts and historical background of quantum chemistry and then explains those of DFT, showing how the latter fits into the bigger picture. Recent interesting topics of DFT in chemistry are also targeted. In particular, the physical meanings of state-of-the-art exchange-correlation functionals and their corrections are described in detail. Owing to its unconventionality, this book is certain to be of great interest not only to chemists but also to solid state physicists.
