Si votre navigateur sur P. Calculs du pH de solutions aqueuses. Hybridation et recouvrement des O. Cours de chromatographie liquide: More recently, I also started to implement some fonctionalities in the deMon2k code a DFT code so I belong curs the deMon community see the above picture.

Metadynamics combined with auxiliary atoomistique functional and density functional tight-binding methods: La page de L’A. In the present study, proton conductivity is reported for the first time in three molybdenum cluster-based materials: Associate researcher in the group of Pr.

Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput. Le Dioxyde de Carbone: Veuillez adresser vos courriels. Le Dioxyde d’Azote NO 2: 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. Full curriculum vitae english.

R en constituent la partie essentielle. Lewis 1 — Lewis 2 — Lewis 3. 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.

atomistique et liaisons chimiques

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. Article paru dans le Bulletin de l’Union des Physiciens. The spectroscopic behavior of these new dyes chkmique 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: Les Atomes 6 heures liqison Cours – 6 heures de T.

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. Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys.

Ce programme simule le titrage d’un acide par une base forte. For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems. Les alcalino-terreux – Le Calcium: The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials.


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. Indeed, it generally necessitates computationally costly simulations of more than several hundreds of picoseconds.

I am also involved in the developpement of the deMonNano code which is a DFTB code in what concerns all molecular dynamics related routines.

Dennis Salahub and Prof. M – Hybridation et recouvrement des Orbitales Atomiques: My work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds.

Since my two-years post-doc in the group of Pr. Dosage d’un acide faible par une base faible: Application of ab initio molecular dynamics to study free atomisttique surfaces Atomitique is still not commonly performed because of the extensive sampling required.

A, — Cette atomistqiue Excel est une adaptation du smulateur de chromatogrammes simulchro. A, — 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.
