Graph Chatbot

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.

In situ characterization of a high work hardening Ti-6Al-4V prepared by electron beam melting

Helena Van Swygenhoven, Nicola Casati

A multi-phase Ti-6Al-4V prepared by electron beam melting and thermal post treatments has been shown to exhibit increased strength and ductility over standard wrought or hot isostatic pressed Ti-6-Al-4V. The mechanical improvements are due to a prolonged, ...

The present article describes the preliminary design studies for PETALE (Programme d'Etude en Transmission de l'Acier Lourd et ses Elements), an oncoming experimental program in the CROCUS reactor. Within the framework of the Venus-Eole-Proteus collaborati ...

ASTM INTERNATIONAL2018

Since the early of the 19th century, canning is one the most efficient ways to preserve foods. Tinplated steel has been used since the beginning for this purpose and it is still one of the most used materials for cans production because it combines the goo ...

Soluble and Solid Iron Reduction Assays with Desulfitobacterium hafniense

Julien Maillard

There is a pressing need to develop sustainable and efficient methods to protect and stabilize iron objects. To develop a conservation-restoration method for corroded iron objects, this bio-protocol presents the steps to investigate reductive dissolution o ...

Study on Bainite/Martensite Transformation in Reheated Weld Metals

Roland Logé, Cyril Cayron, Gaojun Mao, Rui Cao

A new combination of laser scanning confocal microscope (LSCM) and electron backscattering diffraction (EBSD) with a field-emission scanning electron microscope (SEM) is utilized to study the mechanism of bainite transformation in reheated low carbon baini ...

Characterisation and hydration of ye'elimite containing cements

Frank Bullerjahn

Calcium sulphoaluminate cements (CSA) with the main phase yeâelimite are a promising class of non-Portland cements which are gaining increasing interest from the cement industry. However, the hydration kinetics of CSA cements varies strongly, even for ce ...

Enantioselective C-H Functionalization-Addition Sequence Delivers Densely Substituted 3-Azabicyclo[3.1.0]hexanes

Nicolai Cramer, Julia Pedroni

An enantioselective C-H functioffalization route to perfluoroalkyl-containing 3-azabicyclo[3.1.0]-hexanes is disclosed. A modular and bench-stable diazaphospholane ligand enables highly enantioselective Pd(0)-catalyzed cyclopropane C-H functionalization us ...

Bacterial inactivation with iron citrate complex: A new source of dissolved iron in solar photo-Fenton process at near-neutral and alkaline pH

César Pulgarin, Andrzej Sienkiewicz, Cristina del Socorro Lonfat

This study reports the first application of Fe-citrate-based photo-Fenton chemistry for the inactivation of Escherichia coil. Promising results of bacterial inactivation at near-neutral and alkaline pH conditions were obtained, while using low iron concent ...

Fatigue design criteria for strengthening metallic beams with bonded CFRP plates

Alain Nussbaumer, Masoud Motavalli, Mario Fontana, Elyas Ghafoori

Different failure criteria used to prevent fatigue crack initiation in metallic members are described. A series of closed-form analytical solutions were developed to predict the fatigue resistance of metallic beams after strengthening with carbon fiber-rei ...
