Single-shot Electron Imaging of Dopant-induced Nanoplasmas
Abstract: We present single-shot electron velocity-map images of nanoplasmas generated from dopedhelium nanodroplets and neon clusters by intense near-infrared and mid-infrared laser pulses. Wereport a large variety of signal types, most crucially depending on the cluster size. The commonfeature is a two-component distribution for each single-cluster event: a bright inner part withnearly circular shape corresponding to electron energies up to a few eV, surrounded by anextended background of more energetic electrons. The total counts and energy of the electrons inthe inner part are strongly correlated and follow a simple power-law dependence. Deviations fromthe circular shape of the inner electrons observed for neon clusters and large helium nanodropletsindicate non-spherical shapes of the neutral clusters. The dependence of the measured electronenergies on the extraction voltage of the spectrometer indicates that the evolution of thenanoplasma is significantly affected by the presence of an external electric field. This conjecture isconfirmed by molecular dynamics simulations, which reproduce the salient features of theexperimental electron spectra
Electron Correlation Dynamics in Atomic Kr Excited by XUV Pulses and Controlled by NIR Laser Pulses of Variable Intensity
Abstract: We have investigated the possibility to track and control correlation dynamics of valence electrons in krypton (Kr) initiated by the absorption of one extreme ultraviolet (XUV) photon. In this investigation, pump-probe experiments have been performed where monochromatized single high-harmonics at photon energies 29.6, 32.8, and 35.9 eV have been used as pump to populate different intermediate excited states. A temporally delayed near-infrared (NIR) pulse probes the population of various decay channels via the detection of Kr2+ ion yields and its transient profiles. We observe that by varying the NIR pulse intensity within a range from 0.3 × 1013 to 2.6 × 1013 W cm−2, the shape ...

Molecules in Superfluid Helium Nanodroplets
This open access book covers recent advances in experiments using the ultra-cold, very weakly perturbing superfluid environment provided by helium nanodroplets for high resolution spectroscopic, structural and dynamic studies of molecules and synthetic clusters. The recent infra-red, UV-Vis studies of radicals, molecules, clusters, ions and biomolecules, as well as laser dynamical and laser orientational studies, are reviewed. The Coulomb explosion studies of the uniquely quantum structures of small helium clusters, X-ray imaging of large droplets and electron diffraction of embedded molecules are also described. Particular emphasis is given to the synthesis and detection of new species by mass spectrometry and deposition electron microscopy.
Nanodroplets
Nanodroplets, the basis of complex and advanced nanostructures such as quantum rings, quantum dots and quantum dot clusters for future electronic and optoelectronic materials and devices, have attracted the interdisciplinary interest of chemists, physicists and engineers. This book combines experimental and theoretical analyses of nanosized droplets which reveal many attractive properties. Coverage includes nanodroplet synthesis, structure, unique behaviors and their nanofabrication, including chapters on focused ion beam, atomic force microscopy, molecular beam epitaxy and the "vapor-liquid- solid" route. Particular emphasis is given to the behavior of metallic nanodroplets, water nanodroplets and nanodroplets in polymer and metamaterial nanocomposites. The contributions of leading scientists and their research groups will provide readers with deeper insight into the chemical and physical mechanisms, properties, and potential applications of various nanodroplets.
Modeling, Analysis, and Control of Smart Energy Systems
The increasing demand for cleaner and more intelligent energy solutions poses a challenge that resonates across academic, engineering, and policymaking spheres. The complexity of integrating renewable energy sources, energy storage solutions, and advanced communication technologies demands a comprehensive understanding, rigorous analysis, and innovative control strategies. The academic community, in particular, seeks a guiding light through this intricate maze of evolving energy dynamics. Modeling, Analysis, and Control of Smart Energy Systems is a groundbreaking publication that offers more than theoretical exploration; it is a roadmap equipped with the knowledge and tools required to shape the future of energy systems. From laying conceptual foundations to unraveling real-world case studies, the book seamlessly bridges the gap between theory and application. Its comprehensive coverage of mathematical modeling, dynamic system analysis, intelligent control strategies, and the integration of renewable energy sources positions it as an authoritative reference for researchers, engineers, and policymakers alike.
Molecular Beams in Physics and Chemistry
This Open Access book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.
Marine Ecosystems
Marine ecosystems are very productive and include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which has different physical and biological characteristics. The biodiversity of some of these ecosystems is very rich and abundant, offering unique opportunities for high-yield production of proteinaceous material, which is a source of high-quality foods. Biodiversity is fundamental to sustaining marine ecosystem services, such as food security, maintenance of water quality, and recovery from perturbations, which are currently being threatened worldwide. The main threats to marine biodiversity are habitat loss, eutrophication, overexploitation, pollution by hazardous ...

Gouvernance et conduite de l'action publique au 21e siècle
Resum: L'inici del segle XXI ha centrat moltes imaginacions entorn de l'aparició de noves ansietats, amenaces reals, riscos provats i incerteses sobre la capacitat dels estats de dominar la construcció del futur al voltant dels valors compartits i projectes de solidaritat. Aquest és realment un problema de renovació i adaptació de l'acció pública. Aquest llibre confronta les opinions d'experts i les experiències dels actors sobre els avantatges i els béns d'una bona governança democràtica, interactiva i de múltiples actors, al voltant d'una acció pública fundadora del benestar i cohesió social.
