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.
A review. Wet-chem. approaches to multi-component hybrid nanocrystals (HNCs), that incorporate nanoscale domains of different semiconductor, metallic and/or oxide materials interconnected through inorg. junctions, are illustrated and discussed. Control of ...
Parylene films loaded with TiO2 are reported as hotocatalysts in azo dye discoloration processes. The TiO2 loading of the parylene film was 0.32% (w/w) and the amount of TiO2 on the film was about two orders of magnitude below the TiO2 added in suspension ...
Three anthraquinone dyes with carboxylic acid as anchoring group are designed and synthesized as sensitizers for dye-sensitized solar cells (DSSCs). Preliminary photophys. and photoelectrochem. measurements show that these anthraquinone dyes have very low ...
The relation between the VOC, light intensity, φ, and accumulated charge, Q, was studied for dye-sensitized solar cells (DSCs) contg. different counterions for the iodide/triiodide redox couple. At higher light intensities, VOC scaled in the order Cs+ > K+ ...
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 ...
The carbon-free LiFePO4 (olivine) was modified by a monolayer coverage with [12-(2,5-di-tert-butyl-4-methoxy-phenoxy)-dodecyl]-phosphonic acid, coded DW. Thin film electrodes were bonded with 5% PVDF and deposited on F-doped SnO2 (FTO) support. The surface ...
Four Zn(II)-tetra(carboxyphenyl)porphyrins in soln. and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to det. the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectr ...
A perylene imide sensitizer and a covalently-linked perylene imide-naphthalene diimide dyad were prepd. and characterized by absorption and emission spectroscopies, electrochem., and spectroelectrochem. These compds. were chemisorbed on nanoporous Ni oxide ...
A porphyrin ‘‘Mille-Feuilles” photo-electrode is fabricated layer-by-layer by deposition of anionic [zinc meso-tetrakis(p-sulfonato phenyl) porphyrin]4- (ZnTPPS4−) and positively charged polypeptides on a 11-mercaptoundecanoic acid-modified gold electrode ...
A phenomenally high molar extinction coefficient heteroleptic ruthenium(II) complex [Ru(4,4′-carboxylic acid-2,2′- bipyridine)(4,4′-(4-{4-methyl-2,5-bis[3-methylbutoxy]styryl}-2,5-bis[3- methylbutoxy]-2,2′-bipyridine)(NCS)2] (DCSC13) was synthesized by inco ...
