Nuclear magnetic resonance (NMR) is an analytical tool used by chemists and physicists to study the structure and dynamics of molecules. In recent years, no other technique has grown to such importance as NMR spectroscopy. It is used in all branches of science where precise structural determination is required and where the nature of interactions and reactions in solution is being studied.
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.
This book provides an overview of recent developments in experiments probing the fractional quantum Hall (FQH) states of the second Landau level, especially the \nu=5/2 state. It summarizes the state-of-the-art understanding of these FQH states. It furthermore describes how the properties of the FQH states can be probed experimentally, by investigating tunneling and confinement properties. The progress towards the realization of an experiment, allowing to probe the potentially non-Abelian statistics of the quasiparticle excitations at \nu=5/2 is discussed. The book is intended as a reference for graduate students, PostDocs and researchers starting in the field. The experimental part of this book gives practical advice for solving the experimental challenges which researchers studying highly fragile FQH states are faced with.
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.
This book provides an overview of the application of IR spectroscopy in mineralogical investigations, as well as modern trends in the IR spectroscopy of minerals. It includes the most important methodological aspects; characteristic IR bands of different chemical groups and coordination polyhedra; application of IR spectroscopy to the investigation of the crystal chemistry of amphiboles, phyllosilicates, tourmalines etc.; neutral molecules entrapped by microporous minerals; and analysis of hydrogen in nominally anhydrous minerals. About 1600 IR spectra (illustrations as well as a list of wavenumbers) of minerals and some related compounds are accompanied by detailed descriptions of the standard samples used. Each spectrum provides information about the occurrence, appearance, associated minerals, its empirical formula, and unit-cell parameters. The book also provides insights into sample preparation and/or spectrum registration methods. It includes IR spectra of 1020 minerals that were not covered in the book "Infrared spectra of mineral species: Extended library" published in 2014 and written by one of the authors. On average, each page provides information on two minerals/compounds. Subsections correspond to different classes of compounds (silicates, phosphates, arsenates, oxides etc.). About 290 new spectra have been obtained, and the remaining 1310 spectra are taken from most reliable literature sources (published over the last 60 years) and are redrawn in a unified style.

In addition to these in-depth chapters, an introductory overview provides the basic principles of solution and solid-state NMR spectroscopy. Each section also contains a discussion of advances in each area directly attributable to NMR spectroscopy. A final chapter suggests future directions for the deployment of this powerful technology in environmental science.
This book reviews the HL-LHC experiments and the fourth-generation photon science experiments, discussing the latest radiation hardening techniques, optimization of device & process parameters using TCAD simulation tools, and the experimental characterization required to develop rad-hard Si detectors for x-ray induced surface damage and bulk damage by hadronic irradiation. Consisting of eleven chapters, it introduces various types of strip and pixel detector designs for the current upgrade, radiation, and dynamic range requirement of the experiments, and presents an overview of radiation detectors, especially Si detectors. It also describes the design of pixel detectors, experiments and characterization of Si detectors. The book is intended for researchers and master's level students with an understanding of radiation detector physics. It provides a concept that uses TCAD simulation to optimize the electrical performance of the devices used in the harsh radiation environment of the colliders and at XFEL.
Most research and all publications in mass spectrometry address either applications or practical questions of procedure. This book, in contrast, discusses the fundamentals of mass spectrometry. Since these basics (physics, chemistry, kinetics, and thermodynamics) were worked out in the 20th century, they are rarely addressed nowadays and young scientists have no opportunity to learn them. This book reviews a number of useful methods in mass spectrometry and explains not only the details of the methods but the theoretical underpinning.
This thesis reports a major breakthrough in discovering the superconducting mechanism in CeCoIn5, the "hydrogen atom" among heavy fermion compounds. By developing a novel theoretical formalism, the study described herein succeeded in extracting the crucial missing element of superconducting pairing interaction from scanning tunneling spectroscopy experiments. This breakthrough provides a theoretical explanation for a series of puzzling experimental observations, demonstrating that strong magnetic interactions provide the quantum glue for unconventional superconductivity. Additional insight into the complex properties of strongly correlated and topological materials was provided by investigating their non-equilibrium charge and spin transport properties. The findings demonstrate that the interplay of magnetism and disorder with strong correlations or topology leads to complex and novel behavior that can be exploited to create the next generation of spin electronics and quantum computing devices.
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.

Simulation of materials at the atomistic level is an important tool in studying microscopic structures and processes. The atomic interactions necessary for the simulations are correctly described by Quantum Mechanics, but the size of systems and the length of processes that can be modelled are still limited. The framework of Gaussian Approximation Potentials that is developed in this thesis allows us to generate interatomic potentials automatically, based on quantum mechanical data. The resulting potentials offer several orders of magnitude faster computations, while maintaining quantum mechanical accuracy. The method has already been successfully applied for semiconductors and metals.

This thesis addresses the development of a new force spectroscopy tool, correlation force spectroscopy (CFS) for the measurement of the properties of very small volumes of material (molecular to m3) at kHz-MHz frequency range. CFS measures the simultaneous thermal fluctuations of two closely-spaced atomic force microscopy (AFM) cantilevers. CFS then calculates the cross-correlation in the thermal fluctuations that gives the mechanical properties of the matter that spans the gap of the two cantilevers. The book also discusses development of CFS, its advantages over AFM, and its application in single molecule force spectroscopy and micro-rheology.

This thesis describes a new approach for cell analysis by the rapid developing microfluidic technology. The nominee has made great contributions to develop a new analysis platform which combined microfluidic devices with mass spectrometry to determine the trace compounds secreted by cells. Based on this analysis platform, she studied the specific cell secreting behaviors under controlled microenvironment, of which the secretion compounds were qualified and semi-quantified by mass spectrometry. A novel cell sorting device integrated homogenous porous PDMS membrane was invented to classify cells from real samples based on the size difference. The nominee further studied the signal transmission between different cells, and the signal chemicals were qualitative and quantitative monitored by the analysis platform. This indicates the potential significant application of the new cell analysis platform in medicine screening and early diagnosis.
This book discusses group theory investigations of zincblende and wurtzite semiconductors under symmetry-breaking conditions. The text presents the group theory elements required to develop a multitude of symmetry-breaking problems, giving scientists a fast track to bypass the need for recalculating electronic states. The text is not only a valuable resource for speeding up calculations but also illustrates the construction of effective Hamiltonians for a chosen set of electronic states in crystalline semiconductors. Since Hamiltonians have to be invariant under the transformations of the point group, the crystal symmetry determines the multiplet structure of these states in the presence of spin-orbit, crystal-field, or exchange interactions. Symmetry-breaking leads to additional coupling of the states, resulting in shifts and/or splittings of the multiplets. Such interactions may be intrinsic, as in the case of the quasi-particle dispersion, or extrinsic, induced by magnetic, electric, or strain fields. Using a power expansion of the perturbations these interaction terms can be determined in their parameterized form in a unique way. The hierarchic structure of this invariant development allows to estimate the importance of particular symmetry-breaking effects in the Hamiltonian. A number of selected experimental curves are included to illustrate the symmetry-based discussions, which are especially important in optical spectroscopy. This text is written for graduate students and researchers who want to understand and simulate experimental findings reflecting the fine structure of electronic or excitonic states in crystalline semiconductors. |
