Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
The trinuclear Ru complexes [RuCl2(PAd2Bu)]3 (1) and [RuCl2(PtBu2Cy)]3 (2) were obtained by reaction of [(p-cymene)RuCl2]2 with 2 equiv of the resp. sterically demanding phosphine. Crystallog. analyses of 1 and 2 show that the three metal fragments are con ...
EARTH scientists have long recognized(1-4) that the soluble organic acids excreted by soil biota enhance rates of mineral weathering, thereby chemically stratifying the soil and affecting the biodegradation pathways of organic matter, including pollutants( ...
The silver, copper and gold complexes of tripodal N-heterocyclic carbene (NHC) ligand, 1,1,1-tris[(3-methylimidazol-1-yl-2-ylidene)methyl]ethane were prepd. and characterized. The silver complex of the title ligand, TIMEMe was prepd. by reaction of [H3TIME ...
Ruthenium-based anticancer chemotherapies are making significant advances in clinical trials. Until recently, the focus has been on coordination complexes, and mechanisms such as "activation by reduction" and "transferrin-targeted delivery" have been propo ...
Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...
The invention relates to a novel class of ligands, complexes comprising such ligands and a metal ion, and adducts of these metal complexes and a macromolecule. Pharmaceutical compositions and methods of making and using the ligand-metal complexes are also ...
Metal speciation significantly influences the geochemical cycling of trace metals and can control metal bioavailability and toxicity, Advanced analytical techniques have been applied to address some difficulties encountered in identifying metal organic spe ...
A review with 74 refs. is given on fabrication of metalizations and interconnects in microelectronics. An application of metal complexes for laser-assisted CVD is described. Different methods for pre-nucleation and developing of films and lines are discuss ...
