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.

Blob motion and control in simple magnetized plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji

Intermittent convective transport caused by coherent structures, or blobs, are universally observed in the edge of laboratory plasmas. Besides being of fundamental physics interest, the dynamics of these structures in fusion reactors influence the density ...

Sliding of rough surfaces and energy dissipation with a 3D multiscale approach

Jean-François Molinari, Guillaume Anciaux

The purpose of this paper is to present a novel approach to study sliding friction by the use of 3D multiscale coupling techniques. We highlight the difficulties of using multiscale schemes that couple molecular dynamics (MD) with finite elements to perfor ...

TEM cell testing of cable noise reduction techniques from 2 MHz to 200 MHz - Part 1

William Christopher Evans

This paper presents empirical results of cable noise reduction techniques as demonstrated in a TEM cell operating with radiated fields from 2 - 200 MHz. It is the first part of a two-paper series. This first paper discusses cable types and shield connectio ...

Proton-induced fixed positive charge at the Si(100)-SiO2 interface

Alfredo Pasquarello

Positively charged defects induced by protons at the Si(100)-SiO2 interface are studied through density-functional calculations and realistic interface models. Protons generally preserve the bonding network, but cause the spontaneous breaking of strained b ...

Capacitive micro force sensors manufactured with mineral sacrificial layers

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Simon Wiedmer

In this work a prototype of micro force sensor of range μN...mN is presented. Instead of the traditional piezoresistive strain sensing through thick-film resistors used for higher forces, a more effective principle is used: measurement of beam displacement ...

Polymerization of ionic monomers in polar solvents: kinetics and mechanism of the free radical copolymerization of acrylamide/acrylic acid

Jutta Christine Wandrey, Ignacio Rintoul

A precise data set describing the kinetics of the free radical copolymn. of acrylamide/acrylic acid (AM/AA) in the range of low total monomer concn. as a function of the pH, total monomer concn., initiator concn., and comonomer ratio is presented. Strong i ...

Quantifying Pb and Cd complexation by alginates and the role of metal binding on macromolecular aggregation

Cristina Lamelas, Fabrice Avaltroni

The Pb and Cd binding capacity of alginates were quantified by the determination of their complex stability constants and the concentration of complexing sites using H+,Pb 2+,orCd2+ selective electrodes in both static and dynamic titrations. Centrifugation ...

2005

Stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O-3 (PZT)-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d(33)-loop measurements in individual ...

2003

Metal-semiconductor-metal detectors have been fabricated based on AlGaN grown on Si by molecular beam epitaxy. Field distribution and collection efficiency were studied with the ion beam induced charge collection method. The results were explained by numer ...
