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.
Good quality ab initio calcns. (MP2) show that the water adducts of BX3 and CX3+ have totally different structures (X = F-I). While all H2O-BX3 complexes have classical Cs sym. structures with strong B-O bonds and addnl. H-bonding, the heavier CX3+ cations ...
A review, with over 209 refs., is given on the prepn. and structures of all known salts of the known homopolyat. cations of the chalcogens and halogens. The structures of these cations, many of which are nonclassical and cluster-like, arise from pos. charg ...
Using a first-principles approach, we investigate nitrogen bonding configurations at nitrided Si(001) surfaces and Si(001)-SiO2 interfaces by comparing calculated core-level shifts with measured photoemission spectra. Fully relaxed model structures are gen ...
Upon treating elemental S with [AgSbF6], [AgAl(hfip)4], [AgAl(pftb)4] (hfip = OCH(CF3)2, pftb = OC(CF3)3), [Ag(S8)2][SbF6] (1), [AgS8][Al(hfip)4] (2), and [Ag(S8)2]+[Al(pftb)4]- (3) formed in SO2 (1), CS2 (2), or CH2Cl2 (3). 1-3 Were characterized by singl ...
We present a hybrid time-dependent d. functional/mol. mechanics (TDDFT/MM) simulation study on the optical properties of aminocoumarins in gas phase and soln. As solvation is described through a mol. approach, the effects due to the inhomogeneities of the ...
We introduce a new low temperature bonding technology to assemble two microstructured glass substrates for the realization of microchannels for miniaturized chemical analysis applications. To realize the microchannels, we introduce, besides the well-known ...
A new approach combining electrostatic and covalent bonds was established for the formation of resistant capsules with long-term stability under physiol. conditions. Three kinds of interactions were generated in the same membrane: (1) electrostatic bonds b ...
A review. The theor. modeling of chem. active transition metal (TM) centers is a notoriously difficult task. The metal-ligand interactions in these complexes are often highly directional and the concoction of suitable analytic interaction potentials can be ...
First-principles molecular dynamics simulations are carried out to study the structural properties of liquid GeSe2. We use a generalized gradient approximation for the exchange and correlation energy, which we find to improve significantly upon the local d ...
Using a first-principles approach, we assign N 1s core-level shifts at ammonium exposed Si(001)2x1 surfaces to definite bonding configurations of N atoms. Model structures are obtained by fully relaxing the atomic positions of N atoms in different bonding ...
