Chattez avec Graph Search
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.
Kinetics and mechanisms of As(III) oxidation by free available chlorine (FAC-the sum of HOCl and OCl-), ozone (O-3), and monochloramine (NH2Cl) were investigated in buffered reagent solutions. Each reaction was found to be first order in oxidant and in As( ...
New mercury organic compounds with 1-3 metal centers and different substituents were synthesized as anion-selective ionophores. They were incorporated into solvent polymeric membranes, and the selectivity, slope of response, response time, emf repeatabilit ...
Tris(β-diketonato)europium(III) with a series of variably fluorinated ligands derived from 3,5-heptanedione were synthesised with the aim of determining their hydration state under extraction conditions. The number of coordinated water molecules was determ ...
Herein is reported an investigation towards the stereoselective synthesis of inherently chiral pseudorotaxanes. Chiral ammonium threads were readily prepared in five steps from racemic or enantiopure (M or P) salts of di-n-propyl-1,13-dimethoxyquinacridini ...
An encapsulation device, designed on the basis of the laminar jet break-up technique, is characterized for cell immobilization with different types of alginate. The principle of operation of the completely sterilizable encapsulator, together with technique ...
The hexadentate bispidine-based ligand 2,4-bis(2-pyridyl)-3,7-bis(2-methylenepyridine)-3,7-diazabicyclo[3.3.1]nonane-9-on-1,5-bis(carbonic acid methyl ester), L-6m, with four pyridine and two tertiary amine donors, based on a very rigid diazaadamantane-der ...
The behavior of arsenite (AsIII), arsenate (AsV), monomethylarsonate (MMA), dimethylarsinate (DMA), arsenobetaine (AsB) and arsenocholine (AsC) in pyrolytic graphite coated graphite (pyrocoated) tubes was studied. The influence of a tungsten carbide coatin ...
Etched Al of uniform quality is obtained at a const. rate by pptg. Al(OH)3 from the bath with simultaneous regeneration of the NaOH or KOH. The pptn. is promoted by addn. of Na2CO3. Filterability of the ppt. is improved by the addn. of complexing agents, e ...
The reaction of (arene)RuCl2 (arene = C6H6 cymene, C6H3Et3, or C6Me6) or Cp*RhCl2 with 3-hydroxy-2-pyridone in the presence of Cs2CO3 gives trinuclear metallamacro-cyclic complexes. The self-assembly process was shown to be completely diastereose ...
Secretory component (SC), a glycoprotein with an apparent molecular weight of approximately 80,000, has been isolated from rabbit milk and found to be heterogenous in size and charge. Functionally intact IgA dimer has been dissociated from milk secretory I ...
