Texto completoequilibrium geometry calculations for Ni2 dimer, Ni13 and Ni55 nanoclusters
and ethylene adsorption on Ni(100), Ni(111), Ni2, and Ni13 were studied quantum mechanically by means of energetic and kinetic differences. Ethylene hydrogenation on Ni(111) was simulated by use of DFT/B3LYP/6-31G** formalism. The reaction mechanism was mainly composed of three elementary steps. Firstly, ethylene adsorption on bare Ni(111) surface was performed. Second step and third step were the formation of ethane from adsorbed ethylene by use of two types of hydrogen atom, bulk and surface. During the hydrogenation reaction of ethylene on Ni(111), bulk hydrogen atom, representing for hydrogen atoms emerging from the bulk of Ni metal, was determined to be rather reactive than surface hydrogen atom, as suggested by experimental findings. Small Ni clusters, Ni2 and Ni13, were investigated by means of DFT/B3LYP/modified-6-31G**. Equilibrium geometry calculations resulted in Ni2 binding energy of 1.078eV/atom, showing good agreement with experimental value. Ni13 was found to have a structure of icosahedral, suggested experimentally, and binding energy of 2.70eV/atom. Ni55 was, also, studied by semi-empirical PM3 formalism, resulting in expected icosahedral structure. Finally, DFT/B3LYP/6-31G** investigation of ethylene adsorption was performed on Ni(111), Ni(100) and Ni13 surfaces which were selected according to their nickel atom coordination numbers of 9, 8 and 6, respectively. Comparison of adsorption energies of -18.00kcal/mol, -31.4kcal/mol and -43.42kcal/mol, respectively, indicated that the change in energies for ethylene adsorption on different nickel surfaces was directly proportional to coordination number of the nickel atoms constructing the surfaces.

Texto completoThe very first stages of the growth of NiO/Cu(111) interface, were characterized on a microscopic scale including chemical, morphological, and structural aspects. Different elaboration procedures were used and we combined in-situ laboratory and synchrotron radiation techniques. Complete exchange coupled NiO/FeNi/Cu(111) bilayer system have also been investigated. The metallic Ni/Cu(111) interface has been studied, evidencing the close relationship between morphology, structure and magnetic properties. The reduced spin magnetic moments were correlated with the Ni-Cu 3d hybridization and with the Cu capping. The in-plane orbital moment anisotropy, related with the Ni tetragonalization, confirms that the easy axis of magnetization is in the plane for all measured thin nickel films. Ultra-thin NiO films, obtained through MBE evaporation of NiO nuggets, were grown at room temperature and at 250ʿC. The resulting system can globally be described in terms of a spontaneous NiO/Ni/Cu(111) layering. Confirming the STM real-space observations, GISAXS experiments and calculations allowed evidencing the self-organized nature of the NiO islands obtained at room temperature. Due to the poor oxidizing efficiency of the molecular oxygen, the NiO films deposited from metallic Ni at 250ʿC, exhibit several differences with respect to those obtained by NiO nuggets evaporation at room temperature. A cluster nucleation/aggregation mechanism was proposed, based on the STM observations. Formation of a-Ni2O3 hexagonal phase, or structural distortion of the NiO(111)( )R30ʿ structure could both explain the LEED and GIXD results. Exchange coupled NiO/FeNi/Cu(111) bilayer was elaborated using both, NiO nuggets and metallic Ni in oxygen partial pressure evaporation. Sharp NiO/FeNi interfaces were obtained, with textured NiO. Structural analysis of the NiO films deposited on FeNi/Cu(111) films evidenced twinned NiO(111), in much better epitaxy than the oxides deposited on the Cu(111) substrate

Texto completoThe fiberizing spinners used to produce the glass fibers undergo sizable mechanical, chemical and thermal solicitations. Therefore, this piece is degraded and must be periodically replaced. The purpose of these works is to increase the lifetime of the fiberizing spinners by improving the mechanical and chemical properties of the superalloys that constitute them. More precisely, the objective of this thesis is, in the first time, to improve the alloys used to fiberize at 1000°C, and in a second time, to find a superalloy that can fiberize at 1125°C. These works are focused on two families of superalloys: nickel-based and cobalt-based. The chemical properties are characterized by the thermogravimetry tests and the mechanical properties by 3 points flexural creep tests. For the Ni-based alloy, the influences of unwanted minority elements, Mn and Si, were studied. The mechanical properties of this alloy are subject to improvement tests by the addition titanium, zirconium, tantalum, hafnium and niobium. The aluminium addition was also experimented but with the aim of improving the chemical properties of the alloy. Finally, the studies were also driven on the addition of noble metals (Pd and Ru) and of rare earths (Y, La and Ce). Concerning the cobalt-based superalloys, the study focused on an alloy which has previously shown good general properties to be used at 1125°C and no at 1000°C. The versius with a lowered content in tantalum, without tungsten and without hafnium were studied. To close this work, the increase of nickel and a heat treatment were studied in order to improve the oxidation resistance of this second alloy

Texto completoThe present work pertains to the surface science approach to heterogeneous catalysis. In particular model systems for CO2 hydrogenation to methanol, and NO selective catalytic reduction, are investigated by means of a combined approach, where the molecular-level insight provided by a low-temperature scanning tunneling microscope is complemented by density functional theory (DFT) calculations of their electronic structure. To this end, the Inelastic Electron Tunneling Spectroscopy (STM-IETS) technique was introduced for the first time in our laboratory, a recent development which allows to measure the vibrational spectrum of individual molecules adsorbed on a surface. Regarding CO2, we provide single molecule imaging and characterization of CO2/Ni(110), chemisorbed with high charge transfer from the substrate, in an activated state that plays a crucial role in the hydrogenation process. We obtain a detailed characterization of the adsorption geometries and an estimate of the energies corresponding to the different adsorbed states. A consistent picture of CO2 chemisorption on Ni(110) is provided on the basis of the newly available information, yielding a deeper insight into the previously existing spectroscopic and theoretical data. In the Selective Catalytic Reduction (SCR) process, nitrogen oxide is selectively transformed to N2 by reductants such as ammonia. The specificity of this reaction was tentatively attributed to the formation of NH3-NO coadsorption complexes, as indicated by several surface science techniques. Here we characterize the NH3-NO complex at the atomic scale on the (111) surface of platinum, investigating the intermolecular interactions that tune the selectivity. The structures that arise upon coadsorption of NH3 and NO are analyzed in terms of adsorption sites, geometry, energetics and charge rearrangement. An ordered 2 × 2 adlayer forms, where the two molecules are arranged in a configuration that maximizes mutual interactions. In this structure, NH3 adsorbs on top and NO on fcc-hollow sites, leading to a cohesional stabilization of the extended layer by 0.29 eV/unit cell. The calculated vibrational energies of the individually-adsorbed species and of the coadsorption structure fit the experimental values found in literature within less than 6%. The characterizations and optimizations that had to be tackled in order to successfully perform STM-IETS measurement are eventually presented, focusing in particular on an original method which allows to increase the achieved resolution. Namely, the modulation broadening associated to phase-sensitive detection is reduced by employing a tailored modulation function, different from the commonly-used sinusoid. This method is not limited to STM-IETS, but can be easily applied whenever a lock-in amplifier is used to measure a second derivative.

Resumo: Neste trabalho foi estudado o crescimento de filmes ultra-finos de Sb sobre Ni(111) e In sobre Ni(111), no regime de frações de monocamadas, com o interesse no entendimento da estrutura cristalográfica e eletrônica destas ligas de superfície. Os filmes foram preparadas em ambiente de UHV e caracterizados do ponto de vista da estrutura eletrônica através da técnica experimental de espectroscopia de elétrons (XPS) e cálculos de teoria do funcional da densidade (DFT). Na determinação da estrutura cristalográfica das ligas de superfície foram utilizados LEED-qualitativo e PED (difração de fotoelétrons) e DFT. Os filmes de Sb sobre Ni(111) formaram uma liga substitucional de superfície ordenada na estrutura (Ö 3 x Ö 3) R30 °, seguindo o empacotamento fcc do substrato. Os filmes de In sobre Ni(111) formaram duas fases ordenadas, 2 x 2 e (Ö 3 x Ö 3) R30 ° e , coexistindo na superfície em forma de domínios, ambas as fases formaram ligas substitucionais seguindo o empacotamento fcc do substrato. A estrutura eletrônica do filmes foram estudadas por XPS e interpretadas com a ajuda das simulações de DFT. Em ambos os filmes não houve tranferência de cargas entre os átomos, mas tivemos evidências de uma redistribuição de cargas intra-atômica nos átomos do substrato.
Abstract: In this thesis we present a studied the growth of the ultra-thin films of Sb on Ni(111) and In on Ni(111), in the sub-monolayer regime. The main interest was on the understanding of the crystallography and electronic structure theses surface alloys. The films were grown under UHV conditions and characterized as to their electronic structure by X-ray Photoelectron Spectroscopy (XPS) and simulated theoretically by density functional theory (DFT). To determine the crystallography structure, LEED and photoelectron diffraction (PED) was used. The Sb on Ni(111) films after annealing stabilized as a substitution surface alloy in the ( Ö 3 x Ö 3 ) R 30 ° structure following the fcc substrate. The In on Ni(111) films formed two ordered phases 2x2 and (Ö 3 x Ö 3) R30 ° coexisting on the surface, both the phases formed substitution alloys following the fcc substrate. The electronic structure of both the films didn¿t show evidence of charge transfer between the atoms, but of a possible charge redistribution between the states of the Ni atoms in contact with the evaporated film.
