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.
Novel efficient structured combustion catalysts based on sintered metal fiber filters (MFF) were developed. To increase sp. surface area (SSA), metal fibers were coated by crack-free porous oxide films of SiO2, Al2O3, porous glass, and mesoporous SBA-15 si ...
The formation of sub-micron sized particulates has been studied in a low pressure (0.1 mbar) radio-frequency (13.56 MHz) capacitively coupled plasma discharge. Particles are studied in situ by infrared absorption spectroscopy, laser illumination and Cavity ...
A generic method is described for the reversible immobilization of polyhistidine-bearing polypeptides and proteins on attenuated total reflecting (ATR) sensor surfaces for the detection of biomol. interactions by FTIR spectroscopy. Nitrilotriacetic acid (N ...
Metal nickel and copper grids are shown to be suitable supports for structured combustion catalysts. The increase of sp. surface area (SSA) of metal grids was achieved due to the porous outer layer with the structure of Raney metal developed on the wire su ...
The crystallisation kinetics of amorphous sol-gel PZT thin films were investigated using high-temperature X-my diffraction. Crystallisation for different isotherms was monitored as a function of time. Phase transformation data were obtained from integrated ...
We report a synchrotron-radiation-excited photoemission study of the adsorption of W(CO)6 on Si(111)2 x 1. W(CO)6 is shown to adsorb molecularly on Si at 100 K, and to undergo dissociation at room temperature (RT). Exposure of a reacted surface at 100 K to ...
A model for the electrochem. promotion induced by electrochem. generated promoting species is proposed. The formation rate of promoters is assumed to be proportional to the availability of free surface sites at the solid electrolyte/catalyst/gas three-phas ...
The electronic structure of ex situ grown highly oriented thin films of the quasi-ID organic metal tetrathiafulvalene tetracyanoquinodimethane (TTF-TCNQ) has been characterized by means of temperature-dependent high-resolution angle-resolved photoemission ...
Plasma treatment of PET films was carried out under argon, followed by exposure to an oxygen atmosphere. The films underwent considerable changes in surface composition and morphology, as demonstrated by contact angle measurements, FTIR-ATR, AFM, and XPS. ...
The catalytic activity of IrO2 catalyst films for the gas phase combustion of ethylene can be increased by up to a factor of 10 via anodic polarization of the IrO2 catalyst relative to a Au electrode both deposited on Y2O3-stabilized ZrO2 solid electrolyte ...
