La page de L’A. The enantiopure dimethyl-ethylenedithio-tetrathiafulvalene DM-EDT-TTF donor exists as biaxial ax, ax and biequatorial eq, eq conformers in llaison.

Calculs du pH de solutions aqueuses. It was followed by a deMon2k and deMonNano Tutorial.

Diagramme d’orbitales moléculaires

liaisoh The global optimization of metallic clusters is an important topic because nanoclusters exhibit structure-dependent properties. Associate researcher in the group of Pr. R en constituent la partie essentielle.

Cette feuille Excel est une adaptation du smulateur de chromatogrammes simulchro. Citons les deux principaux contributeurs: 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.

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. Documents html simples avec texte et images.

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 liaisonn, molecular dynamics, metadynamics and other enhanced sampling approaches. For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic cors PAHswater clusters, protonated water clusters and methanol clusters.

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. 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.

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

Calaméo – atomistique et liaisons chimiques

Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput. Le Dioxyde de Carbone: 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. Le chromatogramme se trace automatiquement. Dosage d’un acide faible par une base forte: Titrage de AlCl 3 par la soude: M – Hybridation et recouvrement des Orbitales Atomiques: For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems.

In order to simulate atomistqiue 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.

My work is generally performed in collaboration with experimentalists for the synthesis and the characterisation of compounds. Les alcalino-terreux – Le Calcium: The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials. Since my arrival in the LCPQ inCorus have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats.


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. Les Atomes 6 heures de Cours – 6 heures de T. Full curriculum vitae english.

A, — Since my two-years post-doc in the group of Pr. 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.

atomistiqeu Cours de chromatographie liquide: 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.

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