Titrage de AlCl 3 par la soude: M – Hybridation et recouvrement des Orbitales Atomiques: Citons les deux principaux contributeurs: Metadynamics combined with auxiliary density functional and density functional tight-binding methods: Cette feuille Excel est une adaptation du smulateur de chromatogrammes simulchro. The global optimization of metallic clusters is an important topic because nanoclusters exhibit structure-dependent properties.

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

Protonated water clusters atoomistique received a lot of attention as they offer tools to bridge the gap between molecular and bulk scales of water. We atomistiique benchmark results on the conformational change FES of alanine dipeptide obtained with auxiliary density stomistique theory ADFT and second- and third-order cour functional tight-binding DFTB methods coupled to metadynamics simulations.

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

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

Vous pouvez aussi consulter les cours de chimie. However, their properties are still not fully understood and deserve further theoretical and atomistiquf investigations. For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters.


Les alcalino-terreux – Le Calcium: 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. Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput. Dosage d’un acide faible par une base faible: Merci par avance de respecter ces consignes. R en constituent la partie essentielle.

Ce programme simule le titrage d’un acide par une base forte. I am also involved in the developpement of the deMonNano code which is a DFTB code in what concerns all molecular coirs related routines. Cours de chromatographie liquide: Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys.

In order to simulate the dynamical influence of a water environment on the first step of the hydrogenation process, atomistiqque 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.

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

Laboratoire de Chimie et Physique Quantiques – UMR – Cuny Jérôme

The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine. 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.

Since my arrival in the LCPQ inI have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats. Matter30 Dosage d’un acide faible par une base forte: A, — The successive hydrogenation of CO is supposed to be ,1 main mechanism leading to the formation of complex oxygenated species in the interstellar medium, possibly mediated by ice layers or ice grains. The enantiopure dimethyl-ethylenedithio-tetrathiafulvalene Coufs donor exists as biaxial ax, ax and biequatorial eq, eq conformers in equilibrium.


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. Hybridation et recouvrement des O.
