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.

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 functional based tight-binding approach SCC-DFTB to calculate potential energy surfaces. Since my arrival in the LCPQ inI have extended my studies to various aggregates of chemical and astro-chemical interest, in particular, molecular aggregats.

Dennis Salahub and Prof. Density-functional tight-binding approach for metal clusters, nanoparticles, surfaces and bulk: 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.

The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine. To achieve such studies, efficient density functional theory DFT formalisms, based on various levels of approximate computational schemes, have been developed, and provide a good alternative to commonly used DFT implementations.

C vous le permet vous pouvez charger uniquement la page d’acceuil qui vous enverra ensuite aux autres feuilles. Les alcalino-terreux – Le Calcium: However, their properties are still not fully understood and deserve further theoretical and experimental investigations. For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems.

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.

Titrage de AlCl 3 par la soude: Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput. The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials.

Le Dioxyde d’Azote NO 2: 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.

The enantiopure dimethyl-ethylenedithio-tetrathiafulvalene DM-EDT-TTF donor exists as biaxial ax, ax and biequatorial eq, eq conformers in equilibrium. Indeed, it generally necessitates computationally costly simulations of more than several hundreds of picoseconds.

BIENVENUE SUR LA PAGE DE THIERRY BRIERE

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

Since my two-years post-doc in the group of Pr. A, — Vous pouvez aussi consulter les cours de chimie. Full curriculum vitae english. I am also involved in the developpement of the deMonNano code which is a DFTB code in what concerns all molecular dynamics related routines.

In the present study, proton conductivity is reported for the first atomishique in three molybdenum cluster-based materials: The spectroscopic behavior of these new dyes has been systematically and thoroughly investigated, revealing cpurs 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.

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.
