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 series of imidazolium dicarboxylic acids have been prepd. from the reaction of the 1,3-bis(carboxymethyl)imidazolium zwitterion with the Bronsted acids HX (X = F, Br, Cl, ClO4). The structures of these acids have been established in the solid ...
Because of their outstanding mechanical and chemical properties, transition metal nitrides are widely accepted materials in the protective coatings industry. This work aims at elucidating the origin of their exceptional properties. The study concentrates o ...
In aqueous solutions under mild conditions, Ru(H2O)(6) was reacted with various water-soluble tertiary phosphines. As determined by multinuclear NMR spectroscopy, reactions with the sulfonated arylphosphines L = mtppms, ptppms and mtppts yielded only ...
The molecular forms of LiF, LiFHF and Na2SiF6 have been stabilized using trinuclear metallamacrocyclic complexes of (cymene)Ru-II, (Cp*)Rh-III and (Cp*)Ir-III as specific receptors. The host-guest complexes were characterized by NMR spectroscopy and single ...
Hexafluoro-2-butyne, CF(3)Cequivalent toCCF(3), reacts with the triangulo-clusters [Pt-3 (mu-CO)(3)(PR3)(3)] to give the diplatinum(o) compounds [Pt-2(CO)(2)(PR3)(2)(mu-eta(2):eta(2)-CF(3)Cequivalent toCCF(3))] {PR3=PPh3 (1), PBzPh(2) (2), PCy3 (3), (PPr3) ...
The reaction of chloromethyl thiocyanate with 1-methylimidazole affords the imidazolium salt, 1-thiocyanomethyl-3-methylimidazolium chloride, [C1SCNmim]Cl (1a). Exchange of the chloride anion in 1a by [PF6] ...
The reaction of [ReBr3(CO)(3)]NEt4 with 3-hydroxy-1,2,3-benzotriazine-4 (3 H) -one in the presence of base gave the ionic rhenium complex [ReBr(C7H4N3O2)(CO)(3)][NEt4] (2) which was crystallographically characterized. A neutral metallamacrocycle 3 was ...
Polarized fluorescence spectra were recorded in the vicinity of the Se and Br K edges on crystals of the selenated protein aldose reductase in complex with a brominated inhibitor molecule. The X-ray absorption, refraction and resonant scattering tensors as ...
We present a way to fabricate high-aspect-ratio silicon microcavity arrays which can be used for the investigation of confinement-induced ordering phenomena within colloid solutions. In these studies, the microcavity arrays serve as containers for confinem ...
High-resolution transmission electron microscopy (HRTEM), electron microdiffraction, and X-ray diffraction were used to study hydroxyapatite specimens with particle sizes from a few nanometers to several hundreds of nanometers. Diffuse scattering (without ...
