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.
The characterization of Fe/ZSM5 zeolite materials, the nature of Fe-sites active in N2O direct decomposition, as well as the rate limiting step are still a matter of debate. The mechanism of N2O decomposition on the binuclear oxo-hydroxo bridged extraframe ...
The regioselective and diastereoselective cyclization of acyliminium intermediates generated from aminocyclopropanes on unprotected indoles is presented. The recent results obtained in our group are compared with previous intermolecular reactions with amin ...
Nitrous oxide is the third most important gas contributing to global warming and its concentration in the atmosphere is still on the rise. Nitric acid production represents the largest source of N2O in the chemical industry, with a total annual emission of ...
The reaction mechanism on the formation of the hydrosulfido complex [Re(SH)(CO)(3)(bipy)] via the reaction of [Re(OH)(CO)(3)(bipy)] with carbon disulfide was theoretically investigated at the B3LYP/6-31+G(d, p) (LANL2DZ+f for Re) level of theory taking int ...
Many signal processing algorithms include numerical problems where the solution is obtained by adjusting the value of parameters such that a specific matrix exhibits rank deficiency. Since rank minimization is generally not practicable owing to its integer ...
Density functional theory is employed to investigate atomic layer deposition mechanism of HfO2, on Ge(I 0 0)-2 x I surface. Both the HfCl4 and H2O half-reactions proceed through an analogous trapping-mediated mechanism. The neighboring hydroxyl in the reac ...
The use of zeolites for catalytic reactions is a field in continuous development. Since it was demonstrated that metal-zeolites are efficient catalysts for NOx abatement, decomposition of nitrous oxide (N2O) over Fe-containing zeolites has attracted great ...
The solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) was studied over a Pd/ZnO structured catalyst and compared to its behavior in water-assisted conditions. The catalytic behavior was correlated with the s ...
Hydrogen is one of the essential reactants in the chemical industry, though its generation from renewable sources and storage in a safe and reversible manner remain challenging. Formic acid (HCO2H or FA) is a promising source and storage material in this r ...
Tribocorrosion is a material deterioration or transformation resulting from simultaneous action of wear and corrosion. Tribocorrosion is found in many engineering applications but the involved mechanisms are still little understood. The investigation of tr ...
