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.

Merci par avance de respecter ces consignes. Vous pouvez aussi consulter les cours de chimie. A, — I am also involved in the developpement of the deMonNano code which is a DFTB code in what concerns all molecular dynamics related routines.

Cette feuille Excel est une adaptation du smulateur de chromatogrammes simulchro. Calculs du pH de solutions aqueuses. The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and cnimique materials.

atomistique et liaisons chimiques

Protonated water clusters have received a lot of attention as they offer tools to bridge the gap between molecular and bulk scales of water. The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine.


Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys. Full curriculum vitae french. Dosage d’un acide faible par une base forte: Dennis Salahub and Prof. Dosage d’un acide faible par une base faible: Density-functional tight-binding approach for metal clusters, nanoparticles, surfaces and bulk: 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 liauson, metadynamics and other enhanced sampling approaches.

Full curriculum vitae english. In the present study, proton conductivity is reported for the first time in three molybdenum cluster-based materials: Documents html simples avec texte et images. M – Hybridation et recouvrement des Orbitales Atomiques: The global optimization of metallic clusters is an important topic because nanoclusters exhibit structure-dependent properties. Le chromatogramme se trace automatiquement.

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. For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems. Les alcalino-terreux – Le Calcium: Matter30 Exercices de base P.

For instance, some recent studies were devoted to the properties and reactivity of polycyclic aromatic hydrocarbons PAHswater clusters, protonated water clusters and methanol clusters.


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

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. Application of ab initio molecular dynamics to study free energy surfaces FES is still not commonly performed because of the extensive sampling required. Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput.

C vous le permet vous pouvez charger uniquement la page d’acceuil qui vous enverra ensuite aux autres feuilles. However, their properties are still not fully understood and deserve further theoretical and experimental investigations.
