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 this thesis, the electronic structures of low-dimensional carbon allotropes have been studied. In particular, the spatially-resolved photocurrent responses of devices comprising carbon nanostructures were investigated through scanning photocurrent micro ...
This paper is concerned with an investigation of electron transfer between cytochrome P450scc (CYP11A1) immobilized on nanostructured rhodium-graphite electrodes. Multi-walled carbon nanotubes (MWCNT) were deposited onto the rhodium-graphite electrodes by ...
Molecular dynamics modeling shows that multiwall carbon nanotubes (MWCNTs) with sp(3) interwall bonding have strengths exceeding those of single-wall carbon nanotubes (SWCNTs) containing the same size initial intrawall defect, and are far less sensitive to ...
Multi-walled carbon nanotubes functionalized by carboxylic groups, exhibit better affinity towards TiO2 (P90, Degussa) as compared to that of pristine nanotubes. Also the electrochemical performance of TiO2 is improved by nanotube networking, but the Li-st ...
The supramolecular assembly of Ru-bipyridine complex, coded Z-907Na, with single-walled carbon nanotube (SWNT) exhibits unique redox behavior, which is applicable for the nanotube wiring of LiFePO4 (olivine). Cyclic voltammograms of thin films of Z-907Na/S ...
The subject of this work is the study of the electrochemical promotion of catalysis (EPOC), also called non-Faradaic electrochemical modification of catalytic activity (NEMCA). In this phenomenon, application of small currents or potentials on catalysts in ...
The main objectives of this work are 2-fold : The development of a novel type of composite material based on carbon nanofibers supported on sintered metal fibers filters (CNF/SMF) and to explore the use of this material as a catalytic support for a model r ...
We identify a class of covalent functionalizations that preserve or control the conductance of single-walled metallic carbon nanotubes. [2+1] cycloadditions can induce bond cleaving between adjacent sidewall carbons, recovering in the process the sp(2) hyb ...
This thesis reports on the investigations performed on electrochemical functionalization and photoelectronic transport properties of individual single-wall carbon nanotubes (SWCNTs). The first part of the thesis is concerned with the controlled modificatio ...
This thesis describes the synthesis, characterisation and macroscopic manipulation of carbon nanotubes. Two interconnected aspects were investigated: (i) growth of carbon nanotubes by catalytic chemical vapour deposition of acetylene and (ii) assembly and ...
