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.
A combined variable-temp. and multiple field 17O NMR, EPR and NMRD study was performed for the 1st time on Gd(III) complexes of cryptand ligands, L1 and L2, where L1 contains three 2,2'-bipyridine units ([bpy.bpy.bpy]) and L2 is the disubstituted Me ester ...
With a view to develop drugs that could resist hydrolysis in aq. media,organometallic arene-capped ruthenium(II) 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (RAPTA) complexes bearing chelating carboxylate ligands have been prepd. and studied. The new com ...
During the last two decades, magnetic resonance imaging (MRI) has evolved into one of the most powerful techniques in medical diagnosis. Among the various medical diagnostic modalities, such as X-ray or ultra-sound imaging, MRI is the technique of choice e ...
A unified strategy for the synthesis of mauritines A (I), B, C, and F has been developed based on a key intramol. nucleophilic arom. substitution reaction (SNAr) for the formation of the strained 14-membered paracyclophane. It was demonstrated that the out ...
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 first part of this work deals with oxidative addition reactions of the triangulo platinum cluster [Pt3(μ-CO)3(PCy3)3]. Reactions with the electrophilic molecules ICH2CN and X2 (X = I and Br) and with the weakly polar reagent Ph3SnH have been studied. A ...
The application describes ligands for binding targets, the ligands preferably including peptides having at least one sulfated or sulfonated amino acid. The ligand preferably specifically binds to heparin binding sites of biomolecules. Compositions, systems ...
The cyanobacterial metabolite anachelin, postulated to serve as a biological ligand to Fe (siderophore), is composed of a fascinating blend of polyketide, peptide, and alkaloid building blocks. In particular, the latter consists of a N,N-dimethyltetrahydro ...
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 ...
This work deals with the engineering of a new luminescent complex of lanthanide, able to be specifically grafted onto biological materials and to emit a characteristic light useful in quantifying the concentration of the target molecules. We have based our ...
