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.
In this work, we study two examples of frustrated magnetic systems whose degrees of freedom are spins (or pseudo-spins) on two-dimensional lattices. The first part presents the results obtained for the quantum compass model on a square lattice. This model ...
Reactions of tBuP(NH2)2 with Group 13 trialkyls MR3 (M = Al, Ga, In; R = Me, tBu) were investigated in detail. According to variable-temp. (VT) NMR investigations, the reaction proceeds stepwise with the initial formation of aminophosphane adducts, which s ...
Traditional reliable servers require costly design changes to the processor, use custom system or application software, or cannot scale beyond a few processing elements. We present TRUSS, a family of server architectures providing reliable, scalable comput ...
We report on X-ray photoemission of core levels, valence band studies using angle-integrated photoemission, and magnetization measurements of ruthenocuprate and SrRuO3 polycrystalline samples. The data indicate that the RuO2 planes are the source of the en ...
A new series of iridium(III) mixed ligand complexes TBA[Ir(ppy)2(CN)2] (1), TBA[Ir(ppy)2(NCS)2] (2), TBA[Ir(ppy)2(NCO)2] (3), and [Ir(ppy)2(acac) (4) (ppy = 2-phenylpyridine; acac ...
Recently, the sigma-aromaticity model proposed for cyclopropane by Dewar was employed to account for the stability of Group 8 trinuclear metal-carbonyl compds. [M3(CO)12] (M = Fe, Ru, Os). This paper further examines this hypothesis and provides the first ...
Following introductory remarks on the "future history" of superconductivity, I discuss several discrepances concerning doping dependence of the "pseudogap" and open questions across the complex electronic phase diagram. I argue that once we understand the ...
Planar tetracoordinate carbons (ptC's) can be stabilized by four-membered ring perimeters composed of four bare transition metal atoms. DFT analyses of the MOs, electronic structures, energies, and magnetic properties of these CM4 species (where M represen ...
Metathesis reactions of dinuclear halo-bridged complexes of the late transition metals were studied by NMR. For selected combinations of 15 different complexes, asym. complexes are formed in a dynamic equil. The equil. consts. were calcd. and the trends th ...
A non-volatile random access memory (NVRAM) of the type with magnetoresistive memory elements (1) connected by sets of non-intersecting conductor sense lines (3, 4) which define the address of each memory element (1) and are connectable to a magnetic write ...
