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.
The kinetics and oxidation products (OPs) of tramadol (TRA), an opioid, were investigated for its oxidation with ferrate (Fe(VI)) and ozone (O-3). The kinetics could be explained by the speciation of the tertiary amine moiety of TRA, with apparent second-o ...
The present invention relates proteins from the group consisting of CNNM1, CNNM2, CNNM 3 and CNNM4, its derivatives or fragments thereof for use as a medicament, for treatment and or diagnostic purposes. The invention further relates to a human genomic DNA ...
Asym. substituted biaryldiphosphine ligands I (R1 = C1-6-alkyl or C3-10-cycloalkyl optionally substituted with one or more halogen atoms; R2 and R3 are equal and are C5-10-cycloalkyl or C1-6-alkyl, or R2 is C5-10-cycloalkyl or C1-6-alkyl, and R3 is aryl op ...
A dyestuff shown by the formula (1), ML 1 L 2 L 3 (1) wherein M represents an element belonging to Group 8 to Group 10 of the long format Periodic Table, L 1 and L 2 individually represent a bidentate ligand shown by the formula (2), L 3 represents a biden ...
A series of homologous bis-cyclometalated iridium(III) complexes Ir(2,4-di-X-phenyl-pyridine)2(picolinate) (X = H, F, Cl, Br) HIrPic, FIrPic, ClIrPic, and BrIrPic has been synthesized and characterized by NMR, X-ray crystallography, UV–vis absorption and e ...
Carbon-carbon bond forming reactions are among the most important and useful methods for organic synthesis. During the last years, significant progress has been made in this field. Whereas many catalysts were developed for the coupling of aryl, alkenyl, an ...
Bond separation reactions of highly branched alkanes are used to assess (de)stabilizing interactions associated with various 1,3-nonbonded substituent patterns. While n- and singly methylated alkanes show positive bond separation energies (BSEs), which inc ...
The present invention concerns an intermediate of the following formula (I) in which R1 and R2 represent independently of each other a C1-C12 alkyl group, a (C1-C12 alkoxy)carbonyl group, optionally substituted by one, two or three halogen atom, a (C2-C12 ...
Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
The present invention concerns an intermediate of the following formula I in which R 1 and R 2 represent independently of each other a C 1 -C 12 alkyl group, a (C 1 -C 12 alkoxy)carbonyl group, optionally substituted by one, two or three halogen atom, a (C ...
