Abstract

Laser desorption/ionization (LDI) mass spectrometry on porous silicon (MS) is a promising alternative to matrix-assisted laser desorption/ionization (MALDI) MS for the study of small molecules. Indeed, LDI-MS employs nanostructured porous silicon surfaces instead of organic matrices to assist the analyte desorption/ionization, which greatly limits the interference generated in the low m/z range, and thus allows the analysis of low molecular weight compounds. In addition, the use of porous silicon surface has the potential to provide other valuable advantages, such as the dual-polarity capabilities of the substrate, the compatibility with multimodal experiments and the possibility to functionalize the surface to improve the selectivity or the limit of detection of the technique. However, the use of porous silicon surfaces in real applications first requires a good understanding of the different aspects of the LDI-MS technique, including for example the impact of the nanosubstrate morphology on the desorption/ionization process harshness (analytes fragmentation). The objective of this Master’s thesis is to gain a better understanding of the desorption/ionization process occurring on porous silicon surfaces to ultimately optimize them for the LDI-MS analysis of small molecules such as metabolites or organic pollutants.

Abstract

The representation of the Earth's surface in global monitoring and forecasting applications is moving towards capturing more of the relevant processes, while maintaining elevated computational efficiency and therefore a moderate complexity. These schemes are developed and continuously improved thanks to well instrumented field-sites that can observe coupled processes occurring at the surface–atmosphere interface (e.g., forest, grassland, cropland areas and diverse climate zones). Approaching global kilometer-scale resolutions, in situ observations alone cannot fulfil the modelling needs, and the use of satellite observation becomes essential to guide modelling innovation and to calibrate and validate new parameterization schemes that can support data assimilation applications. In this book, we review some of the recent contributions, highlighting how satellite data are used to inform Earth surface model development (vegetation state and seasonality, soil moisture conditions, surface temperature and turbulent fluxes, land-use change detection, agricultural indicators and irrigation) when moving towards global km-scale resolutions.

Abstract

High-energy astrophysics involves the study of exceedingly dynamic and energetic phenomena occurring near the most extreme celestial objects known to exist, such as black holes, neutron stars, white dwarfs, and supernova remnants. High-Energy Astrophysics provides graduate and advanced undergraduate students with the most complete, self-contained introduction to the subject available. This textbook covers all the essentials, weaving together the latest theory with the experimental techniques, instrumentation, and observational methods astronomers use to study high-energy radiation from space. Fulvio Melia introduces topics at the forefront of today's research, including relativistic particles, energetic radiation, and accretion disk theory. No other textbook offers such a thorough yet concise treatment of the key aspects of high-energy astrophysics--both theoretical and observational--or delves as deeply into modern detection techniques, satellite systems, and analytical and numerical modeling used by theoreticians. Amply illustrated, High-Energy Astrophysics is also ideal for researchers interested in the application of fundamental physical laws to understand how matter and radiation behave in regions of the universe where physical conditions are most extreme.Uniquely weaves together the theoretical and experimental aspects of this important branch of astronomy Features stunning images of the high-energy sky Fully describes the principal classes of high-energy sources, with an in-depth study of many archetypal objects within them Provides an excellent, self-contained resource for the classroom, written by a preeminent researcher and teacher in the field
