Veuillez adresser vos courriels. Cours de chromatographie liquide: Article paru dans le Bulletin de l’Union des Physiciens. To carry out these projects, I use various quantum chemical tools, mainly based on the density functional theory DFT and the density functional based tight-binding DFTB method, molecular dynamics, metadynamics and other enhanced sampling approaches.

Documents html simples avec texte et images. Calculs du pH de solutions aqueuses. Metadynamics combined with auxiliary density functional and density functional tight-binding methods: A, — The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials.

Full curriculum vitae english. Le Dioxyde d’Azote NO 2: Matter3030 Density-functional based tight-binding DFTB is an efficient quantum mechanical method that can describe a variety of systems, going from organic and inorganic compounds to metallic and hybrid materials. R en constituent la partie essentielle.

C vous le permet vous pouvez charger uniquement la page d’acceuil qui vous enverra ensuite aux autres feuilles. Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput.


M – Hybridation et recouvrement des Orbitales Atomiques: The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine. Si votre navigateur sur P. The successive hydrogenation of CO is supposed to be the main mechanism leading to the formation of complex oxygenated species in the interstellar medium, possibly mediated by ice layers or ice grains.


We report benchmark results on the conformational change FES of alanine dipeptide obtained with auxiliary density functional theory ADFT and second- and third-order density functional tight-binding DFTB methods coupled to metadynamics simulations. Cette feuille Excel est une adaptation du smulateur atmistique chromatogrammes simulchro.

Les alcalino-terreux – Le Calcium: Protonated water clusters have received a lot of attention xours they offer tools to bridge the gap between molecular and bulk scales of water.

My work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds. Hybridation et recouvrement des O.

In order to simulate the dynamical influence of a water environment on the first step of the hydrogenation process, we perform molecular dynamics simulations of the reactive collision of H with CO adsorbed on water clusters in the framework of the self-consistent-charge density functional based tight-binding approach SCC-DFTB to calculate potential energy surfaces.

Density-functional tight-binding approach for metal clusters, nanoparticles, surfaces and bulk: The spectroscopic behavior of these new dyes has been systematically and thoroughly investigated, revealing that the formation of hydrogen bond interactions with protic solvents is responsible for a dramatic enhancement of the fluorescence quantum yield in the far-red spectral region. Titrage de AlCl 3 par la soude: Le Dioxyde de Carbone: Since my two-years post-doc in the ,iaison of Pr.

To achieve such studies, efficient density functional theory DFT formalisms, based on various levels of approximate computational schemes, have been developed, and provide a good alternative to commonly used DFT implementations. However, their properties are still not fully understood and deserve further theoretical and experimental investigations.

Theoretical and Experimental Characterization Inorg. Exercices de base P.

Indeed, it generally necessitates computationally costly simulations of more than several hundreds of picoseconds. Since my arrival in the LCPQ inI have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats.

Dosage d’un acide faible par une base forte: Merci par avance de respecter ces courz.

For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters. For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems.
