Abstract:
The invention relates to a process for depositing a compact film of particles (4) on the internal surface (10) of a part (2), comprising the following steps: a) placing the part (2) in a carrier liquid (6); b) generating a flow of carrier liquid (44) into the hollow (8) of the part in the direction of the surface (18) of the carrier liquid, so as to create a protuberance (50); c) dispensing the particles (4) in order to form a compact film floating on the liquid (6) between a contact line (20) and an upstream front (6) of particles; and d) transferring the film (4) onto the internal surface (10) by performing a relative displacement between this part (2) and the surface (18) of the carrier liquid, while continuing to dispense particles (4) onto the upstream front (60).
Abstract:
The invention concerns a method for producing a chromatography-enrichment column, the method comprising the following steps: (a) depositing at least one layer of desired particles, which may be identical or different, and are intended to constitute the stationary phase, in a compact assembly, on the flat surface of a substrate; (b) crosslinking the layer in at least the regions corresponding to the desired shape of the enrichment column to be obtained; (c) impregnating the layer with a light radiation-sensitive material; (d) insolating the layer obtained in step (c) so as to form insolated regions of which the shape corresponds to the desired internal shape of the enrichment column, if the light radiation-sensitive material behaves like a positive resin or to form non-insolated regions of which the shape corresponds to the desired internal shape of the enrichment column if the light radiation-sensitive material behaves like negative resin; and (e) eliminating the light radiation-sensitive material in the zones corresponding to the internal shape of the enrichment column. The invention is used in particular in the field of chemical analysis.
Abstract:
The invention addressed a difficult problem in the conventional methods and has its object to provide an organic thin film with flexibility and high strength to be a support for a molecule, with which a biomolecular element or a molecule such as a membrane protein as a biosensor can function equally in a living body, and a method for producing the same. In this invention, the organic thin film to be a support for the biomolecular element or the biosensor molecule is produced by forming a layer of lipid molecules on a layer of fatty acid molecules which is a primary thin film layer formed on an inorganic substrate. Further, by the selection and combination of fatty acid molecules, a thin film structure with a characteristic pattern structure can be obtained.
Abstract:
L'invention concerne une installation (1) pour la formation d'un film compact de particules (4) à la surface d'un liquide porteur (16), comportant une zone (11) formant réservoir de liquide porteur, une rampe inclinée (12), une zone d'accumulation et de transfert de particules (14), des moyens (18) de mise en mouvement du liquide porteur, des moyens de dispense (2) des particules (4) en solution, configurés pour dispenser les particules à la surface du liquide porteur dans la zone formant réservoir, et une structure (50) pour la déflection des particules configurée pour favoriser, selon une direction transversale (31) de l'installation, un étalement des particules (4) en sortie de la zone formant réservoir (11). Selon l'invention, la structure (50) pour la déflection des particules est perméable au liquide porteur (16).
Abstract:
L' invention se rapporte à une installation pour le dépôt d'un film de particules ordonnées (4) sur un substrat en défilement (38), l'installation comprenant : - une zone de transfert (14) comprenant une entrée de particules (22) et une sortie de particules (26) espacées l'une de l'autre par deux rebords latéraux (28) en regard, retenant un liquide porteur (16) sur lequel flottent les particules, et - un pont capillaire (42) assurant la liaison entre le liquide porteur (16) contenu dans la zone de transfert (14) et le substrat (38). Selon l'invention, l'installation comporte une pluralité de buses d'aspiration (32a, 32b) capables d'attirer les particules (4) vers ses deux rebords latéraux (28).

Abstract:
The invention concerns in particular a method for depositing a nanometric multilayer thin film on a substrate from a liquid solution containing at least one surfactant, characterized in that it includes the following steps: forming a film from the solution; contacting the substrate; depositing the film on the substrate. The invention is particularly designed to depositing black films on different types of surfaces, in particular for obtaining highly organized films. The films obtained by said method are particularly useful in electronics and optics.
