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.
The addn. of inert particles of lighter d. and smaller diam. increases considerably the mass transfer coeff. in comparison to that of mono-component active particles at the same liq. velocity. This effect was applied to elimination of Cu ions by adsorption ...
This thesis describes some of three years'work carried at the Centre Suisse d'Electronique et de Microtechnique (Neuchâtel, Switzerland) under the supervision of Dr. Martha Liley and in collaboration with Prof. Horst Vogel of the Ecole Polytechnique Fédéra ...
Photoinduced electron transfer from organic dye molecules to semiconductor nanoparticles is the first and most important reaction step for the mechanism in the so called “wet solar cells” [1]. The time scale between the photoexcitation of the dye and the e ...
Gold nanoparticles of 2–5 nm supported on woven fabrics of activated carbon fibers (ACF) were effective during CO oxidation at room temperature. To obtain a high metal dispersion, Au was deposited on ACF from aqueous solution of ethylenediamine complex [Au ...
This review describes recent advances in the handling and manipulation of magnetic particles in microfluidic systems. Starting from the properties of magnetic nanoparticles and microparticles, their use in magnetic separation, immuno-assays, magnetic reson ...
There is currently much controversy surrounding homogeneous arene hydrogenation catalysis since it has been suggested that the active catalysts are actually heterogeneous. Since many of the proposed homogeneous catalysts operate in water under biphasic con ...
The influence of inert particles on liq./solid mass transfer is studied in fluidized beds by using a binary-mixt. of solids of differing size and d. The addn. of inert particles of higher d. and smaller diam., e.g. glass beads, exerts remarkable effects on ...
The authors used light to transform a colloidal soln. of spherical silver nanoparticles into larger nanoparticles of a different shape. The particle size and shape can be controlled by choosing the wavelength(s) of light used to drive the photochem. growth ...
Nanostructures are known to exhibit novel optical, electrical, and magnetic and many other interesting physical properties and a lot of research has been invested on the synthesis and study of such structures in the recent years. The massive drive towards ...
