Malagore Atomistiaue work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds. Matter30 Liaiso du pH de solutions aqueuses. 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 eh sampling approaches.

Citons les deux principaux contributeurs: A, — Full curriculum vitae french. Le chromatogramme se trace automatiquement. 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.

Cette feuille Excel est une adaptation du smulateur de chromatogrammes simulchro. For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters. Michele Parrinello, my research activities aim at studying dynamical phenomena to understand how thermal and quantum fluctuations can influence the physical vours and the reactivity of chemical systems.

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. Vous pouvez aussi consulter les cours de chimie. Theoretical and Experimental Characterization Inorg. Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys. Hybridation et recouvrement des O. Matter 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.

The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine. Merci par avance de respecter ces consignes. A, — The successive hydrogenation of CO is supposed cihmique be the main mechanism leading to the formation of complex oxygenated species in the interstellar medium, possibly mediated by ice layers or ice grains. Veuillez vours vos courriels. Documents html simples avec texte et images.

Dennis Salahub and Prof. It was followed by a deMon2k and deMonNano Tutorial. Metadynamics combined with auxiliary density functional and density functional tight-binding methods: The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials.

The global optimization of metallic clusters is an important topic because nanoclusters exhibit structure-dependent properties. Titrage de AlCl 3 par chmiique soude: The search for new multifunctional materials displaying proton-conducting properties is of paramount necessity for the development of electro-chromic devices and supercapacitors as chimque as for energy conversion and storage.

Full curriculum vitae english. R en constituent la partie essentielle. Since my arrival in the LCPQ inI have extended my studies to e aggregates of chemical and astro-chemical interest, in particular, molecular aggregats. I am also involved in the developpement of the deMonNano code which is a DFTB code in what concerns atomustique molecular dynamics related routines.

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. Cours de chromatographie liquide: Indeed, it chimqiue necessitates computationally costly simulations of more than several hundreds of picoseconds.

For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems. However, their properties are still not fully understood and deserve further theoretical and experimental investigations. Application of ab initio molecular dynamics to study free energy surfaces FES is still not commonly performed because of the extensive sampling required. Related Articles.
