Francois Tardif has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11396025
    Abstract: 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.
    Type: Grant
    Filed: October 11, 2018
    Date of Patent: July 26, 2022
    Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES

  • Patent number: 9638847
    Abstract: 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.

  • Patent number: 9457348
    Abstract: 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.

  • Patent number: 8900476
    Abstract: 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.

  • Publication number: 20120171682
    Abstract: The present invention relates to a method and a kit for detecting, optionally identifying and optionally quantifying at least one carbon nanotube possibly included in a sample, including the steps consisting in: (a) subjecting said sample to conditions enabling the amplification of a nucleotide sequence using primers capable of amplifying said nucleotide sequence, the possibly included carbon nanotube having been functionalized by said nucleotide sequence prior to step (a), and (b) detecting, optionally identifying and optionally quantifying the amplification product possibly obtained after step (a).
