Available in PDF, EPUB and Kindle. Book excerpt: La microscopie à force atomique (AFM) est un outil puissant et polyvalent capable de réaliser des images avec une résolution sub-nanométrique d'un grand type d'échantillons, comme des surfaces de matériaux inorganiques avec ou sans molécules adsorbées, et d'opérer dans des environnements allant de l'ultra-haut vide (UHV) à l'interface solide/liquide. Parmi les différents modes existants, l'AFM en mode modulation de fréquence (FM-AFM) donne des résultats remarquables grâce à deux boucles de contrôle et une d'asservissement qui s'influencent mutuellement. En contrepartie, la compréhension du fonctionnement de la machine ainsi que l'optimisation de ses réglages s'avèrent délicates. De plus, cette difficulté est accentuée par l'interprétation souvent complexe liée aux phénomènes spécifiques à l'échelle nanométrique. Pour pallier ces difficultés, le travail de thèse a consisté en l'élaboration d'un AFM numérique (n-AFM) à partir d'un code de calcul conçu par L. Nony en langage C. Après une phase d'implémentation en Fortran 90 pour assurer portabilité et compatibilité avec d'autres programmes scientifiques, de nouvelles fonctionnalités ont été développées. Parmi celles-ci, un couplage avec un code de dynamique moléculaire (MD) a été réalisé afin de considérer les effets de température et de relaxation du système imagé. Ces développements du n-AFM ont permis de mettre en oeuvre différents régimes et modes d'utilisation à travers l'étude de plusieurs systèmes. En premier lieu, des molécules bi- et tri-dimensionnelles adsorbées ont permis d'éprouver la sensibilité et la stabilité du n-AFM en simulant un cantilever classique et un tuning fork. En deuxième lieu, la reconstruction de la surface 6H-SiC(3X3) a été étudiée à l'aide de la MD puis du n-AFM. Les images expérimentales de cette reconstruction révèlent un comportement atypique que nous nous sommes efforcés de comprendre et d'expliquer. Enfin, l'utilisation du n-AFM a été étendue à d'autres domaines que l'étude des surfaces et molécules. En particulier, nous avons modélisé et étudié en FM-AFM l'influence d'un défaut sur les parois d'une nano-pointe oscillant à l'interface air/liquide. Et nous avons enfin poursuivi par l'étude de l'influence, sur le comportement d'un AFM en mode modulation d'amplitude (tapping mode), de nano-films de liquide à la surface du système pointe-substrat.

In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Download or read book Post Dryout Heat Transfer written by G.F. Hewitt and published by Routledge. This book was released on 2017-10-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of post-dryout heat transfer has generated great interest because of its importance in determining maximum clad temperature in nuclear reactor loss-of-coolant accidents (LOCAs). An associated phenomenon, the deterioration of heat transfer in boiling, is significant to other industrial sectors. This book provides comprehensive coverage of post-dryout heat transfer, discussing such essential topics as post-dryout heat transfer in dispersed flow, interpretation and use of transient data in surface rewetting by reinstatement of flow or by reducing heat flux, rod bundles, two-phase flow occurrences in the post-dryout region, various methods for predicting ""inverted annular flow,"" and new experiments for measuring thermodynamic nonequilibrium with probes in the channel. The book also presents a basis for independent safety assessment of nuclear reactors and chemical plant systems where post-dryout heat transfer may occur. Post-Dryout Heat Transfer will be a useful reference for researchers and professionals in the nuclear and chemical production industries.
Download or read book On Three Levels written by Mark Fannes and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of a five-day NATO Advanced Research Workshop "On Three Levels, the mathematical physics of micro-, meso-, and macro phenomena," conducted from July 19 to 23 in Leuven, Belgium. The main purpose of the workshop was to bring together and to confront where relevant, classical and quantum approaches in the rigorous study of the relation between the various levels of physical description. The reader will find here discussions on a variety of topics involving a broad range of scales. For the micro-level, contributions are presented on models of reaction-diffusion pro cesses, quantum groups and quantum spin systems. The reports on quantum disorder, the quantum Hall effect, semi-classical approaches of wave mechanics and the random Schrodinger equation can be situated on the meso-level. Discussions on macroscopic quantum effects and large scale fluctuations are dealing with the macroscopic level of description. These three levels are however not independent and emphasis is put on relating these scales of description. This is especially the case for the contributions on kinetic and hydrodynamicallimits, the discussions on large deviations and the strong and weak coupling limits. The advisory board was composed of J.L. Lebowitz, J.T. Lewis and E.H. Lieb. The organizing committee was formed by Ph.A. Martin, G.L. Sewell, E.R. Speer and A.
