Book Description
Direct analysis using mass spectrometry (MS) techniques provide a powerful approach to investigate the molecular composition and spatial distribution of complex samples with high sensitivity and specificity. In particular, these techniques have been widely applied to achieve rapid molecular analysis of complex clinical samples including native tissue samples and biospecimens. Several types of direct analysis MS techniques have been developed for tissue analysis including a variety of ambient ionization MS techniques and matrix-assisted laser desorption ionization (MALDI) MS. Notably, both approaches are highly capable of performing molecular imaging of endogenous metabolites, lipids, and proteins to characterize tissue samples. Furthermore, through applying ambient ionization and MALDI MS imaging techniques, new insights into disease state can be learned by investigating the correlation between spatially resolved molecular information with histological evaluation in tissue samples. Although several other types of direct analysis MS techniques have been developed, this dissertation focuses on advancements using solvent-based ambient ionization MS (e.g. desorption electrospray ionization (DESI)) and MALDI MS imaging methods for tissue analysis and disease characterization. In Chapter 2, a fundamental and systematic investigation of the affect of solvent properties on molecular extraction processes in solvent-based ambient ionization was performed. In Chapter 3, the performance of DESI MS imaging for the analysis and statistical classification of thyroid fine needle aspiration (FNA) biopsies using different solvents, sources, and high-performance MS systems was evaluated. Next, Chapter 4 describes the development of a sample preparation method for MALDI MS imaging to improve detection of various endogenous proteins by selectively reducing signal from hemoglobin proteins in blood-rich tissues. Lastly, in Chapter 5, various MALDI imaging MS methods were applied to characterize the protein and N-glycan molecular signatures in endometriosis tissues and provide new insights into possible mechanisms of endometriosis development and progression. Collectively, this dissertation provides insights into the fundamental aspects, method developments, and applications of direct analysis MS techniques including solvent-based ambient ionization MS and MALDI MS imaging for tissue analysis. Furthermore, this dissertation showcases the exciting and significant potential of direct analysis MS techniques to solve current challenges in the clinic and provide new insights in healthcare and medicine

Book Description
Ambient ionization mass spectrometry (MS) technologies offer a unique opportunity to bring the specificity and sensitivity of MS into clinics, potentially allowing rapid analyses of biospecimens without need for sample preparation or highly trained personnel. As these technologies offer significant advantages over current technologies in terms of speed and suitability for a hospital environment, ambient ionization methods have been applied to a wide variety of clinical applications such as disease diagnosis, therapeutic drug monitoring, and biomarker discovery. Despite these successes, there remain challenges for these methods to overcome before they can be relied upon for routine analysis of patient samples. Prior to their use by physicians to inform decisions regarding patient care, ambient ionization MS technologies must be robust, versatile, and be shown to improve patient outcomes by providing information that is lacking in current standard of care procedures. This dissertation serves to outline recent advancements made towards the improvements of ambient ionization MS technologies as well as the application of these techniques towards disease indications that have yet to be explored. Chapter 2 provides data and discussion about how relative humidity can contribute to variability and poor data quality during desorption electrospray ionization (DESI) MS experiments, providing essential information about how atmospheric conditions can contribute to the robustness of the technique. Chapters 3 and 4 present methods for integration of new separation and fragmentation techniques with ambient ionization methods in order to increase the amount of information that can be gathered from a biological specimen. Finally, Chapter 5 presents results from the utilization of DESI-MS imaging towards understanding endometriosis, a chronic gynecological condition that has limited diagnosis and treatment options for patients. The entirety of this work aims to discuss how further improvements to ambient ionization MS technologies can make them useful for understanding a wider variety of disease processes and the progress that is being made to this end

Book Description
Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.

Book Description
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.

Book Description
Self-healing is a well-known phenomenon in nature: a broken bone merges after some time and if skin is damaged, the wound will stop bleeding and heals again. This concept can be mimicked in order to create polymeric materials with the ability to regenerate after they have suffered degradation or wear. Already realized applications are used in aerospace engineering, and current research in this fascinating field shows how different self-healing mechanisms proven successful by nature can be adapted to produce even more versatile materials. The book combines the knowledge of an international panel of experts in the field and provides the reader with chemical and physical concepts for self-healing polymers, including aspects of biomimetic processes of healing in nature. It shows how to design self-healing polymers and explains the dynamics in these systems. Different self-healing concepts such as encapsulated systems and supramolecular systems are detailed. Chapters on analysis and friction detection in self-healing polymers and on applications round off the book.

Book Description
Chemical sensors are in high demand for applications as varied as water pollution detection, medical diagnostics, and battlefield air analysis. Designing the next generation of sensors requires an interdisciplinary approach. The book provides a critical analysis of new opportunities in sensor materials research that have been opened up with the use of combinatorial and high-throughput technologies, with emphasis on experimental techniques. For a view of component selection with a more computational perspective, readers may refer to the complementary volume of Integrated Analytical Systems edited by M. Ryan et al., entitled “Computational Methods for Sensor Material Selection”.
