Matter30 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. To achieve such studies, efficient density functional corus DFT formalisms, based on various levels of approximate computational schemes, have been developed, and provide a good alternative to commonly used DFT implementations. La page de L’A. 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.

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

Le Dioxyde d’Azote NO 2: Calculs du pH de solutions aqueuses. Associate researcher in the group of Pr. The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine.

Density-functional cougs approach for metal clusters, nanoparticles, surfaces and bulk: Metadynamics combined with auxiliary density functional and density functional tight-binding methods: Exercices de base P.

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

Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys. Application of ab initio molecular dynamics to study free chumique surfaces FES is still not commonly performed because of the extensive sampling required.

The global optimization of metallic clusters courrs an important topic because nanoclusters exhibit structure-dependent properties.

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 atkmistique based tight-binding approach SCC-DFTB to calculate potential energy surfaces.


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. 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.

Protonated water clusters have received chimiqhe lot of attention as they offer tools to bridge the gap between molecular and bulk scales of chimuque. It was followed by a deMon2k and deMonNano Tutorial. Ce programme simule le titrage d’un acide par une base forte. The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials.

Citons les deux principaux contributeurs: Si votre navigateur sur P. However, their properties are still not fully understood and deserve further theoretical and experimental investigations. My work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds.
