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.
Nanoporous ZnO electrodes, dye-sensitized with a ruthenium bipyridyl complex, were used as photoanodes in photoelectrochem. solar cells. By improving the interfacial contact between dyes and ZnO particles in the film, overall solar-to-elec. energy conversi ...
Five azo-dyes: 4-phenylazo-phenol, 4-phenylazo-benzeneamine, 4-phenylazo-benzenethiol, 4-phenylazo-benzoic acid, and 4-phenylazo-pyridine have been prepd. and used as a "test kit" for rapid screening of functional group affinity to metal oxides. The dyes w ...
Effective transverse piezoelectric coefficient e(31,f) has been measured on (100)/(001) sol-gel Pb(ZrXTi1-X) thin films with compositions between 30% and 45% Zr. A maximum value of 8.07 +/- 0.36 C/m(2) at 40% Zr is found. The influence of the poling field ...
The texture of sputter deposited PbTiO3 films could be turned from (100)- to (111)-orientation by adding a few nm thick TiO2 layer onto the textured Pt(111) substrate film. AES, XPS, and XPD measurements showed that such TiO2 films were epitaxially ordered ...
The interaction between the dye cis-bis(4,4'-dicarboxy-2,2'-bipyridine)-bis(isothiocyanato) ruthenium(II), Ru(dcbpyH2)2(NCS)2, and nanostructured ZnO was investigated by photoelectron spectroscopy (PES) using synchrotron radiation. The results are compared ...
An antenna which combines solar cells and printed patches is presented. The antenna is designed so as to accommodate the solar cells that provide power to an MMIC amplifier. A 2×4 array which operates at the frequency of 3.76 GHz and has a bandwidth of 16% ...
