The invention consists of a continuous sorting method and device which highlights the trajectory differences to which fibers of different form factors and particles charged under the joint influence of electrical forces and a centrifugal force could be subjected. Thus, according to the sorting method, the conditions exploit this difference in order to recover/collect the fibers separated from the non-fibrous particles present in the same initial aerosol or to sort fibers exhibiting different form factors.

Method and device for sorting fibers in suspension in an aerosol through the combination of electrostatic and centrifugal forces

A method for producing a colored or fluorescent substrate with a view to formation of a colored or fluorescent image including the formation. The method defines on a substrate of a colored or fluorescent matrix, pixels of at least two different colors, wherein each pixel forms a filter for a given color. At least one filter is an interferential filter or a filter obtained with colored or fluorescent particles.

Method for producing micron-resolution coloured images embedded in a very robust, very durable medium

A device for sampling and transporting nano-objects for analysis thereof. A cassette portion of the device includes two parts with mutual assembly mechanisms between them including a clipping mechanism configured not to be accessible from outside in assembled position of the parts. Therefore, any inopportune opening of the cassette and thus extraction of the sampling filter accommodated in the cassette somewhere else than the place intended for the analysis are avoided.

Device for sampling and transporting nano-objects contained in aerosols for the analysis thereof

The invention relates to a heat-transporting fluid and to the use thereof. The heat-transporting fluid of the invention is formed of an aqueous colloidal sol including water and up to 58.8 wt %, relative to the total fluid weight, in a-Al2O3 particles, the thickness of which is the smallest dimension and less than or equal to 30 nm 90% to 95% of said a-Al2O3 particles have a size less than or equal to 210 nm, among which 50% have a size less than or equal to 160 nm. The invention is of use in the field of cooling, in particular nuclear reactor backup cooling.

This optical coding device comprises a plurality of aggregates suitable for emitting infrared, visible or ultraviolet rays by luminescence, at least one of the said aggregates comprising at least one luminophore. This aggregate further comprises at least one particle consisting of a surface plasmon effect material, the said luminophore and the said particle being suitable for entering into interaction.
