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 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 ...
Reactions designed to give Se6[Sb(OTeF5)6]2 by the reaction of Se2Br2, 4Se, and 2Ag[Sb(OTeF5)6] lead to products that include [Ag2(Se6)(SO2)2][Sb(OTeF5)6]2 (1). The distorted cubic (Ag2Se6+2)n consists of a Se6 mol. bicapped by two silver cations (local D3 ...
THE exchange of metal ions between an oxide mineral surface and water occurs in a wide range of processes, including corrosion(1), the breakdown, of inhaled dusts(2,3), soil formation(4) and the cycling of toxic substances in the environment(5). In studies ...
The reaction of the aminophosphane C6H4(o-CN)NHPPh2 with elemental potassium in the presence of 18-crown-6 affords the phosphinoamide-containing complex [C6H4(o-CN)N-PPh2(THF)(18-Crown-6)K] which has been fully characterised in solution and the solid state ...
We determined the structure of the hydrated Cu(II) complex by both neutron diffraction and first-principles molecular dynamics, In contrast with the generally accepted picture, which assumes an octahedrally solvated Cu(II) ion, our experimental and theoret ...

WE present the first comparative study of the uptake of metal ions by neurones, performed for Zn, Cr, Co, Mo, Al, Ni, Mn and Cd. The study reveals substantial differences in the uptake of different metals, under similar exposure procedures. In particular, ...
Salt effects exerted on the cycloetherification of linear diarylheptanoid 3-OH-4-MeOC6H3(CH2)2COCMe2CO(CH2)2C6H3-3-F-4-NO2 were investigated. Both salting-in and salting-out alkali salts were found to inhibit the macrocyclization. Ion-pairing exchange was ...
A method for the facile prepn. of oligoribonucleotide analogs contg. b-D-allo-furanosyl nucleosides with addnl. functional groups tethered to the 6'-O positions is presented. It is based on the synthesis in two protected nucleosides carrying a 6'-O-bromope ...
