Packed with reviews plus new results from the author's
laboratories, the first-of-its-kind work offers a timely and
authoritative treatise on the use of mass spectral techniques in
organic stereochemistry.
This thesis focuses on the study of the optical response of new atomically thin two-dimensional crystals, principally the family of transition metal dichalcogenides like MoS2. One central theme of the thesis is the precise treatment of the linear and second-order nonlinear optical susceptibilities of atomically thin transition metal dichalcogenides. In addition to their significant scientific interest as fundamental material responses, these studies provide essential knowledge and convenient characterization tools for the application of these 2D materials in opto-electronic devices. Another important theme of the thesis is the valley physics of atomically thin transition metal dichalcogenides. It is shown that the degeneracy in the valley degree of freedom can be lifted and a valley polarization can be created using a magnetic field, which breaks time reversal symmetry in these materials. These findings enhance our basic understanding of the valley electronic states and open up new opportunities for valleytronic applications using two-dimensional materials.

Topological Insulators (TIs) are insulators in the bulk, but have exotic metallic states at their surfaces. The topology, associated with the electronic wavefunctions of these systems, changes when passing from the bulk to the surface. This work studies, by means of infrared spectroscopy, the low energy optical conductivity of Bismuth based TIs in order to identify the extrinsic charge contribution of the bulk and to separate it from the intrinsic contribution of the surface state carriers. The extensive results presented in this thesis definitely shows the 2D character of the carriers in Bismuth-based topological insulators. The experimental apparatus and the FTIR technique, the theory of optical properties and Surface Plasmon Polaritons, as well as sample preparation of both crystals and thin films, and the analysis procedures are thoroughly described.
Magnetic impurities in a non-magnetic host metal have been actively explored in condensed matter physics in recent last decades. From both fundamental and applied viewpoints these systems are very interesting because they can exhibit strong electronic correlations that give rise to various fascinating phenomena beyond the single particle picture. Up to now our understanding of the underlying processes remains limited due to difficulties involved in measuring these systems on a microscopic scale. With their unique control, scanning tunneling microscopy (STM) and spectroscopy (STS) allow for the first time investigations of phenomena occurring on very small length and energy scales. Here, single magnetic iron and cobalt atoms embedded beneath a metal surface are investigated using these techniques. In particular, the transition from single impurity Kondo physics to two interacting impurities is studied in real space. This thesis contains a comprehensive description of the STM /STS technique, sub-surface impurities, as well as single- and two-impurity Kondo physics - and as such offers a valuable introduction to newcomers to the field.
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 gained such significance as NMR spectroscopy. It is
used in all branches of science in which precise structural
determination is required and in which the nature of interactions
and reactions in solution is being studied. "Annual Reports on NMR
Spectroscopy" has established itself as a premier means for the
specialist and non-specialist alike to become familiar with new
techniques and applications of NMR spectroscopy.
This comprehensive presentation of the integral equation method as applied to electro-analytical experiments is suitable for electrochemists, mathematicians and industrial chemists. The discussion focuses on how integral equations can be derived for various kinds of electroanalytical models. The book begins with models independent of spatial coordinates, goes on to address models in one dimensional space geometry and ends with models dependent on two spatial coordinates. Bieniasz considers both semi-infinite and finite spatial domains as well as ways to deal with diffusion, convection, homogeneous reactions, adsorbed reactants and ohmic drops. Bieniasz also discusses mathematical characteristics of the integral equations in the wider context of integral equations known in mathematics. Part of the book is devoted to the solution methodology for the integral equations. As analytical solutions are rarely possible, attention is paid mostly to numerical methods and relevant software. This book includes examples taken from the literature and a thorough literature overview with emphasis on crucial aspects of the integral equation methodology.

This book presents developments of techniques for detection and analysis of two electrons resulting from the interaction of a single incident electron with a solid surface. Spin dependence in scattering of spin-polarized electrons from magnetic and non-magnetic surfaces is governed by exchange and spin-orbit effects. The effects of spin and angular electron momentum are shown through symmetry of experimental geometries: (i) normal and off normal electron incidence on a crystal surface, (ii) spin polarization directions within mirror planes of the surface, and (iii) rotation and interchange of detectors with respect to the surface normal. Symmetry considerations establish relationships between the spin asymmetry of two-electron distributions and the spin asymmetry of Spectral Density Function of the sample, hence providing information on the spin-dependent sample electronic structure. Detailed energy and angular distributions of electron pairs carry information on the electron-electron interaction and electron correlation inside the solid. The "exchange - correlation hole" associated with Coulomb and exchange electron correlation in solids can be visualized using spin-polarized two-electron spectroscopy. Also spin entanglement of electron pairs can be probed. A description of correlated electron pairs generation from surfaces using other types of incident particles, such as photons, ions, positrons is also presented.
This book examines Au (I, III) complexes that selectively attack and inhibit zinc finger proteins (ZnFs) for potential therapeutic use. The author explores gold(I)-phosphine, gold(III) complexes with N^N and C^N donors as inhibitors of the HIV-1 nucleocapsid protein (NCp7), in comparison to the human transcription factor Sp1. To determine the coordination sphere of the gold adducts formed by interaction with ZnFs, two innovative approaches are used, based on Travelling-Wave Ion Mobility coupled with Mass Spectrometry (TWIM-MS), and X-ray Absorption Spectroscopy. Both approaches are proven to yield valuable structural information regarding the coordination sphere of gold in the adducts. In addition, the organometallic compound [Au (bnpy)Cl2] is evaluated. The system is shown to be capable of inhibiting ZnFs by means of C-S coupling.

This book presents studies of complex nanostructures with unique optical responses from both theoretical and experimental perspectives. The theory approaches the optical response of a complex structure from both quantum-mechanical and semiclassical frameworks, and is used to understand experimental results at a fundamental level as well as to form a quantitative model to allow the design of custom nanostructures. The experiments utilize scanning transmission electron microscopy and its associated analytical spectroscopies to observe nanoscale optical effects, such as surface plasmon resonances, with nanometer-scale spatial resolution. Furthermore, there is a focus in the dissertation on the combination of distinct techniques to study the difficult-to-access aspects of the nanoscale response of complex nanostructures: the combination of complementary spectroscopies, the combination of electron microscopy and photonics, and the combination of experiment and theory. Overall, the work demonstrates the importance of observing nanoscale optical phenomena in complex structures, and observing them directly at the nanoscale.

This thesis addresses the evolving field of measurement science, specifically that of mass spectrometry (MS) and ion mobility spectrometry (IMS) based techniques. It focuses on the design, construction and implementation of low-cost, easy-to-manufacture measurement tools that are used in modern settings such as airport security screening. Advances in these technologies often involve minimal performance enhancement at ever-increasing cost, which in turn limits accessibility to versatile measurement tools. This problem is addressed using desktop 3D printers along with widely available materials for the production of novel ion lenses and an IMS instrument with a performance comparable to that of many commercial systems. Bairds findings are a source of inspiration for scientists exploring this emerging field.

This thesis approaches impact resistance in dense suspensions from a new perspective. The most well-known example of dense suspensions, a mixture of cornstarch and water, provides enough impact resistance to allow a person to run across its surface. In the past, this phenomenon had been linked to "shear thickening" under a steady shear state attributed to hydrodynamic interactions or granular dilation. However, neither explanation accounted for the stress scales required for a person to run on the surface. Through this research, it was discovered that the impact resistance is due to local compression of the particle matrix. This compression forces the suspension across the jamming transition and precipitates a rapidly growing solid mass. This growing solid, as a result, absorbs the impact energy. This is the first observation of such jamming front, linking nonlinear suspension dynamics in a new way to the jamming phase transition known from dry granular materials.

After decades of dominance of genetics and genomics, the importance of structural biology is growing exponentially in the field of plant biology. The main objectives of this new book series is to "demystify" structural biology for plant researchers and to provide important insights into the basic molecular mechanisms underlying plant development through the diverse approaches utilized by structural biologists. The book series starts with a theme dedicated to hormonal signaling that has benefited from the application of structural biology. "Plant Structural Biology: Hormonal Regulations" provides up-to-date knowledge of the structural aspects of hormonal signal recognition, signal transduction, hormonal control of downstream regulatory pathways and hormonal crosstalk. The most distinctive features of this book as well as future titles is/will be to provide overview of cutting-edge research in the field of plant structural biology, and to serve as a compendium of various approaches that could be applied to problems being solved in modern plant biology. Last but not least, we hope this book will facilitate and broaden the community of (not only) plant scientists who are interested in structural biology approaches and tools. For these reasons, the style of this series is concise and general, in order to avoiding unnecessary details. Explanatory boxes describing the basics of specific approaches (e.g. X-ray crystallography, NMR, SAXS, molecular dynamics simulations, etc.) are included.
This book is intended to give technological background and practical examples, but also to give general insight into the on-going technology development in the area of biodetection. The content is therefore suitable for an array of stakeholders (decision makers, purchasing officers, etc.) and end-users of biodetection equipment within the areas of health, environment, safety and security, and military preparation. The book is divided into three sections. The first section discusses the fundamental physical and biological properties of bioaerosol's. The second section goes into more detail and discusses in-depth the most commonly used detection principles. The third section of the book is devoted to technologies that have been used in standoff applications. The last section of the book gives an overview of trends in bioaerosol detection. The reader of this book will gain knowledge about the different biodetection technologies and thus better judge their capabilities in relation to desired applications. |
