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.
We investigate the structure and mobility of single self-interstitial atom and vacancy defects in body-centered-cubic transition metals forming groups 5B (vanadium, niobium, and tantalum) and 6B (chromium, molybdenum, and tungsten) of the Periodic Table. D ...
Recently, we have introduced a scheme for optimizing atom-based nonlocal external potentials within the framework of d. functional theory (DFT) in order to systematically improve the description of mol. properties [Phys. Rev. Lett. 93, 153004 (2004); J. Ch ...
The attempt to prep. hitherto unknown homopolyat. cations of sulfur by the reaction of elemental sulfur with blue S8(AsF6)2 in liq. SO2/SO2ClF, led to red (in transmitted light) crystals identified crystallog. as S8(AsF6)2. The X-ray structure of this salt ...
Density-functional theory is used to model interstitial iron and its complexes with aluminum in Si-rich SiGe alloys with Ge concentration up to 8%. Both short-range and long-range defect-Ge interactions are considered. It is found that Fe prefers Si-rich r ...
The thermochem. of the RuO42- + MnO4- RuO4- + MnO42- redox reaction in aq. soln. is studied by sep. d.-functional-based ab initio mol.-dynamics simulations of the component half reactions RuO42- -> RuO4- + e- and MnO42- -> MnO4- + e-. We compare the result ...
A review discusses the basic concepts of the Car-Parrinello method, some of the recent methodol. extensions, focusing on aspects with potential interest for applications in medicinal chem., and the advantages and limitations of new modeling tools. ...
We add an effective atom-centered nonlocal term to the exchange-correlation potential in order to cure the lack of London dispersion forces in std. d. functional theory. Calibration of this long-range correction is performed using d. functional perturbatio ...
Energies computed by B3LYP and other popular DFT functionals are flawed by systematic errors, which can become considerable for larger mols. These errors, predominately due to inadequacies in assessing longer-range non-bonded attractive effects, are illust ...
NOVELTY - The component partially or wholly comprises pigmented ceramic. The pigment comprises nanoparticles of metal of group IB in periodic table, alkaline metals or their alloy, coated with a layer of silica such as crystalline silica. The crystalline s ...
Energies computed by B3LYP and other popular DFT functionals are flawed by systematic errors, which can become considerable for larger mols. These errors, predominately due to inadequacies in assessing longer-range nonbonded attractive effects (dispersion) ...
