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.
Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...
Spectromicroscopy with the imaging technique of X-ray photoelectron emission microscopy (X-PEEM) is a microchemical analytical tool installed in many synchrotron radiation laboratories, and which is finding application in diverse fields of research. The me ...
Tip-enhanced Raman Spectroscopy (TERS) has shown promise as a tool for in situ nanoscale chemical analysis, and is also leading to a better understanding of the fundamentals of surface-enhanced Raman Spectroscopy. In this work, the latest developments, cha ...
Ballistic emission electron and X-ray photoelectron emission microscopy studies are presented for the sulfur-passivated Pt-GaP(001) buried metal-semiconductor interface. The topographic/ballistic images showed that the roughness of the metal-semiconductor ...
The surface electronic and mol. structure of a new org. chromophore useful for dye-sensitized nanostructured solar cells was studied by electron spectroscopy. Initially the use of a simple mol. system contg. the polyene-diphenylaniline chromophore in a sol ...
To better characterize a permanent modifier based on iridium deposited on zirconium or tungsten treated platforms of transversely heated graphite atomizer, and to gain addnl. information about its chem. behavior directed to an eventual further optimization ...
CsI thin film photocathodes of 600 nm thickness deposited on polished Al surfaces by resistive evaporation technique were studied by angle-resolved X-ray photoelectron spectroscopy (ARXPS), before and after UV-irradiation under vacuum. It is shown that the ...
An innovative SiO2-PO43--TiO2 photocatalyst is presented which is able to bond TiO2 to Raschig rings (RR). Evidence for the formation on the catalyst surface of P = O stretching bands near 1200-1250 cm(-1) is presented by FTIR spectroscopy. The TiO2 Deguss ...
The status of the Volume PhotoEmission (VOLPE) project, now operational at ESRF, is reviewed. Commissioning phase and test experiments confirm that high energy resolution (71 meV at 5934 eV kinetic energy) with truly bulk sensitivity is achievable in Hard ...
An efficient, visible light active, N, S-codoped TiO2-based photocatalyst was prepared by reacting thiourea with nanoparticulate anatase TiO2. Commercial anatase powders were manually ground with thiourea and annealed at 400 degrees C in two crucibles with ...
