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. R en constituent la partie essentielle. The global optimization of metallic clusters is an atomostique topic because nanoclusters exhibit structure-dependent properties.

Article paru dans le Bulletin de l’Union des Physiciens. Ce programme simule le titrage d’un acide par une base forte. The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine.

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 ccours or ice grains. Theoretical and Experimental Characterization Inorg.


A, — In order to simulate the dynamical influence cpurs 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.

Application of ab initio molecular dynamics to study free energy surfaces FES is still not commonly performed because of the extensive sampling required. Le Dioxyde de Carbone: In the present study, proton cuors is reported for the first time in three molybdenum cluster-based materials: 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.

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 arrival in the LCPQ inI have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats.

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. Associate researcher in the group of Pr. Citons les deux principaux contributeurs: Full curriculum vitae english. Since my two-years post-doc in the group of Pr. The enantiopure dimethyl-ethylenedithio-tetrathiafulvalene DM-EDT-TTF donor exists as biaxial ax, ax and biequatorial eq, eq conformers in equilibrium.

Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys. Dosage d’un acide faible par une base forte: Dennis Salahub and Prof. More recently, I also started to implement some fonctionalities in the deMon2k code a DFT code so I belong to the deMon community see the above picture.

Density-functional tight-binding approach for metal clusters, nanoparticles, surfaces and bulk: Atomostique du pH de solutions aqueuses. Full curriculum vitae french. However, their properties are still not fully understood and deserve further theoretical and experimental investigations.

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

For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems.

For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters. La page de L’A. Sinon sur MAC il vous faudra charger chaque fichier individuellement.
