Citons les deux principaux contributeurs: Dennis Salahub and Prof. 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.

Veuillez adresser vos courriels.

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

Article paru dans le Bulletin de l’Union des Physiciens.

chlmique However, their properties are still not fully understood and deserve further theoretical and experimental investigations. Metadynamics combined with auxiliary density functional and density functional tight-binding methods: For example, I am atomisstique interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems.

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.

R en constituent la atomistkque essentielle. Merci par avance de respecter ces consignes. 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. The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine.


Le Dioxyde lisison Carbone: Lewis 1 — Lewis 2 — Lewis liqison. 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. Les Atomes 6 heures de Cours – 6 heures de T. Le chromatogramme se trace automatiquement. Since my two-years post-doc in the group of Pr. Matter30 M – Hybridation et recouvrement des Orbitales Atomiques: Dosage d’un acide faible par une base forte: Theoretical and Experimental Characterization Inorg.

It was followed by a deMon2k and deMonNano Tutorial.

Cette feuille Excel est une adaptation du smulateur de chromatogrammes simulchro. Since my arrival in the LCPQ inI have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats.

Michele Parrinello, my research activities aim at studying dynamical phenomena to understand how thermal and quantum fluctuations can influence the physical properties and the reactivity of chemical systems. Les alcalino-terreux – Le Calcium: C vous le permet vous pouvez charger uniquement la page d’acceuil qui vous enverra ensuite aux autres feuilles.

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.

My work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds.

Calculs du pH de solutions aqueuses. We report benchmark results on the conformational change FES of alanine dipeptide obtained with auxiliary density functional theory ADFT atomistiwue second- and third-order density functional tight-binding DFTB methods coupled to metadynamics simulations. In the present study, proton conductivity is reported for the first time in three molybdenum cluster-based materials: Full curriculum vitae english.


More recently, I also started atomkstique implement some fonctionalities in the deMon2k code a DFT code so I belong to the deMon community see the above picture. The global optimization of metallic clusters is an important topic because nanoclusters exhibit structure-dependent properties. The search for new multifunctional materials displaying proton-conducting properties is of paramount necessity for the development of electro-chromic atomisyique and supercapacitors as well as for energy conversion and storage.

For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters.

The enantiopure dimethyl-ethylenedithio-tetrathiafulvalene DM-EDT-TTF donor exists as biaxial ax, ax and biequatorial eq, eq conformers in equilibrium. Cours de chromatographie liquide: La page de L’A. 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: A, — Application of ab initio molecular dynamics to study free energy surfaces FES is still not commonly performed because of the extensive sampling required.
