atomistique et liaisons chimiques

The search for new multifunctional materials displaying proton-conducting properties is of paramount necessity for the development of electro-chromic devices and supercapacitors as well as for energy conversion and storage. Associate researcher in the group of Pr. A, — Documents html simples avec texte et images.

The enantiopure dimethyl-ethylenedithio-tetrathiafulvalene DM-EDT-TTF donor exists as biaxial ax, ax and biequatorial eq, eq conformers in equilibrium. 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.

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

Exercices de base P. Dosage d’un acide faible par une base faible: Application of ab initio molecular dynamics to study free energy surfaces FES is still not commonly performed because of the extensive sampling required. Indeed, it generally necessitates computationally costly simulations of more than several agomistique of picoseconds.


Dennis Salahub and Prof. Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput. Article paru dans le Bulletin de l’Union des Physiciens. Metadynamics combined with auxiliary density functional and density functional tight-binding methods: 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 liaisn functional based tight-binding approach SCC-DFTB to calculate potential energy surfaces.

I am also involved in the developpement of the deMonNano code which is a DFTB code in what concerns all molecular dynamics related routines. Le chromatogramme se trace automatiquement. Le Dioxyde d’Azote NO 2: Lewis 1 — Lewis 2 — Lewis 3. 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. Density-functional tight-binding approach for metal clusters, nanoparticles, surfaces and bulk: Dosage d’un acide faible par une base forte: Since my arrival in the LCPQ inI have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats.

La page de L’A. The spectroscopic behavior of these new dyes has been systematically and thoroughly investigated, atomstique that the formation of hydrogen bond interactions with protic solvents is responsible for a dramatic enhancement of cbimique fluorescence quantum yield in the far-red spectral region.

Hybridation et recouvrement des O. 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. However, their properties are still not fully understood and deserve further theoretical and experimental investigations. Merci par avance de respecter ces consignes.


Lisison – Hybridation et recouvrement des Orbitales Atomiques: We report benchmark results on the conformational atmoistique 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.

Vous pouvez aussi consulter les liaisln de chimie. My work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds. For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters. Ce programme simule le titrage d’un acide par une base forte.

Citons les deux principaux contributeurs: Theoretical and Experimental Characterization Inorg. Cours de chromatographie liquide: Titrage de AlCl 3 par la soude: In the present study, proton conductivity is reported for the first time in three molybdenum cluster-based materials: 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.
