AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This thesis is concerned with supramolecular architectures assembled at metal surfaces. The investigations pursued two objectives. On the one hand, the focus was placed on the fabrication of low-dimensional surface-supported network structures by applying ...
Many low oxidation state transition metal (carbonyl) clusters are salts and are highly soluble in ionic liquids. Since many are also effective catalysts/precatalysts for hydrogenation reactions, we have conducted a catalytic study of these compounds in ion ...
The Gruneisen parameter is equal to about 2 for most substances, Its value is higher in the case of interactions, for example, electron-phonon and exchange interaction, magnetovolume instability. The parameter has very large values for Invar alloys and the ...
The reaction of [RuCl3(AsPh3)(2)(MeOH)] with the dimeric complexes (cod)RhCl, (ppy)RhCl (ppy = cyclometalated 2-phenylpyridine), (cymene)RuCl2 and CP*MCl2 (M = Rh, Ir) has been investigated. The structure of the resulting products was s ...
The nature of the bonding in ethylene and h2-P4 complexes, M(C2H4)2+ and M(h2-P4)2+, of group 11 metal cations (M = Cu, Ag, Au) has been explored by d. functional calcns. On the basis of the evaluation of symmetry orbitals, the contributions from the inter ...
Carbamoyl phosphate (CP) has been implicated as an educt for the synthesis of the CO and CN ligands of the metal centre of [NiFe]-hydrogenases in Escherichia coli, since CP synthetase mutants (carAB) are unable to generate active hydrogenases due to a bloc ...
The fidelity of metal incorporation into the active center of hydrogenase 3 from Escherichia coli was studied by analyzing the inhibition of the maturation pathway by zinc and other transition metals. Hydrogenase maturation of wild-type cells was significa ...
A review. In an effort to develop new tripodal N-heterocyclic carbene (NHC) ligands for small mol. activation, two new classes of tripodal NHC ligands TIMER and TIMENR were synthesized. The C-anchored tris(carbene) ligand system TIMER (R = Me, t-Bu) forms ...
This paper is aimed at introducing the organometallic chemist to the fascinating area of organometallic pharmaceuticals. It commences by identifying the properties of organometallic (transition metal) compounds that lend themselves to medical applications. ...
