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.
Basic thermodynamic considerations are used to rationalize the formation of thermotropic mesophases incorporating aromatic ligands for trivalent lanthanide metal ions (Ln). Standard flat and bent molecular interfaces, separating the central binding unit fr ...
In 2003, the Nobel Assembly at the Karolinska Institute has awarded the Nobel Prize in Medicine or Physiology to Paul Lauterbur and Peter Mansfield for their seminal discoveries concerning the development of Magnetic Resonance Imaging (MRI), a non-invasive ...
Four tetracatenar (L1–L4) and one hexacatenar (L5) ligands, derived from the diaza-18-crown-6 framework, are synthesized and characterized. In these ligands, the amine functions are fitted with benzoyloxybenzyl linker groups, attached either with a carbony ...
Based on the ligand LAB the new heterobitopic ligands LAB2, LAB3, LAB4 and LAB5 have been designed and synthesised. The five ligands were designed to selectively form heterobimetallic complexes of composition LnLn'(L)36 when reacted with a pair of ...
The stability and water exchange dynamics of gadolinium (GdIII) complexes are critical characteristics that determine their effectiveness as contrast agents for magnetic resonance imaging (MRI). A new heteropodal GdIII chelate, [Gd-TREN-bis(6-Me-HOPO)-(TAM ...
The synthesis of the potentially nonadentate ligand 1,4,7-tris[(6-carboxypyridin-2-yl)methyl]-1,4,7-triazacyclononane (H3tpatcn), a new derivative of 1,4,7-triazacyclononane N-functionalised with three pyridinecarboxylate arms, is described. The complexes ...
Specific volumes of forsterite and San Carlos olivine have been measured by in-situ X-ray diffraction at simultaneously high pressure and high temperature up to 7 GPa and 1300 K in a cubic-anvil press coupled to synchrotron radiation. No difference could b ...
Recent neutron-diffraction studies on dilute solutions have shown that a change in coordination numbers from nine to eight water molecules in the first hydration sphere occurs when going from the light to the heavy lanthanide (III) ions. To acquire a deepe ...
