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.
Eight new seven-membered ring iminoalditols, displaying an amino group and a hydroxymethyl group on the ring, have been synthesized from D-arabinose via epoxidation of a protected azacycloheptene and subsequent nucleophilic opening. Three of them show a po ...
The database and information retrieval communities have long been recognized as being irreconcilable. Today, however, we witness a surprising convergence of the techniques used by both communities in decentralized, large-scale environments. The newly emerg ...
The components of nucleus-independent chem. shift (NICS) tensors for Dnh n-annulenes are discussed as indexes of the arom. character of electronic pi systems. The component corresponding to the principal axis perpendicular to the ring plane, NICSzz, is fou ...
To improve implant biocompatibility, we developed a simple cost-effective thermal surface treatment allowing an increase in the oxide layer thickness of a titanium (Ti) alloy used in orthopaedic implants. The goal of this study was to test in vitro the rea ...
This study focuses on the mineralization of 5-amino-6-methyl-2-benzimidazolone (AMBI), an important precursor in the industrial production of dyes, through an integrated Fe(III) photoassisted–biological system without addition of other electron acceptor th ...
A semiconductor photodiode (18) is formed as a pn-junction between a region (2) of a first conductivity type and a region (6) of a second conductivity type. The region (6) of the second conductivity type is approximately hemispherical. A mini guard ring (8 ...
The asym. synthesis of 1,3-lactol-bridged tetrahydroisoquinolines I [R = SiMe2CMe3, CH2Ph; R1 = CH2CH(CO2Me)2; R2 = CO2CH2Ph] was developed. Subsequent cyclizations of I (R = SiMe2CMe3, CH2Ph) under acidic conditions lead to the formation of a tricyclic en ...
The TELEMAC project brings new methodologies from the Information and Science Technologies field to the world of water treatment. TELEMAC offers an advanced remote management system which adapts to most of the anaerobic wastewater treatment plants that do ...
We have integrated an individual nanostructured permalloy ring on a Hall sensor and studied the switching processes in a temperature regime between 4.2 and 90 K in in-plane magnetic fields. The nanoring has an outer diameter of 550 nm. In the ring with a s ...
A reliable procedure was developed for the synthesis of isocyano peptides by dehydration of the corresponding N-formyl derivs. with phosphoryl chloride in combination with triethylamine. The isocyano peptides were prepd. in excellent yields and with min. e ...
