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.
When two different periodic potentials are present at the same time in a solid, the electron wavefunctions must conform to the resulting overall periodicity. It is the case of the broken-symmetry phases which are often observed in low-dimensional systems. ...

Clusters of metal atoms at a fixed size can assume different structural arrangements, known as isomers, which may have nearly the same energy. Therefore at given experimental conditions distribution of these isomers can be present. While the size selection ...
The reactivity of (E)- and (Z)-1-fluorobuta-1,3-diene ((E)- and (Z)-11), 2-fluorobutadiene (12). (E)and (Z)-1-(fluoromethylidene)-2-methylidenecyclohexane ((E)- and (Z)-13) toward SO2 has been explored and compared with that of (Z)- and (E)-1-(fluoromethyl ...
The conformational analysis of a series of configurational isomers of 2-(hydroxymethyl)azepan-3,4,5,6-tetrols 1-4 has been carried out. H-1 NMR spectroscopic data, especially vicinal J couplings and nuclear Overhauser enhancements (NOE), assisted by molecu ...
An aq. soln. of peroxynitrous acid has been studied using first-principles mol. dynamics simulations based on d. functional theory. The relative Helmholtz energies of different conformers have been detd. via thermodn. integration with constraints. At contr ...
Molecular events such as cis/trans isomerization of Xaa-Pro tertiary amide bonds in peptides and proteins are slow on the overall time scale of the formation of a final biostructure and are, therefore rate limiting. In order to pursue a better understandin ...
The design and synthesis of cyclic mimetics of VCAM-1 protein that reproduce the integrin-binding domain are presented. The unprotected peptide precursor 37-43, Thr-Gln-Ile-Asp-Ser-Pro-Leu, was grafted onto functional templates of type naphthalene, bipheny ...
V substituted phosphomolybdic acids could hydroxylate benzene with nearly 100% selectivity at appreciable conversion levels in the presence of oxidizing agents like H2O2 and AcOOH. There appears to be a correlation, for the liq. phase, between phenol yield ...
The authors compare the enantiomeric cross-inhibition of D- and L-guanosine 5'-phosphoro-2-methyl-imidazole (I) polymn. on C10 (RNA), dC10 (DNA), or hC10 (hexitol nucleic acid) (II). RNA or DNA templates catalyze efficient oligomerization of D-I, with a st ...
The most important advances in the field of biomaterials over the past few years have been in bioactive biomaterials. Materials have been developed to incorporate bioactivity through biological recognition, including incorporation of adhesion factors, poly ...
