  • Embedding nanoparticles in thermoplastic polymers
    Patent number: 10626545
    Abstract: The present invention relates to a polymeric material having one or more nanoparticles embedded within the surface layer of a single side of the material. In some embodiments, the nanoparticles are microbiocidal nanoparticles which impart antimicrobial characteristics to the polymeric material within which they sprayed and pushed by are embedded.

  • Method for detecting turbulence conditions, using the interaction of a laser beam with a thin photochromic film, and device for implementing said method
    Patent number: 9684011
    Abstract: A method for assessing turbulence parameters of a medium comprises the following steps: the illumination, by a laser beam being propagated in said medium, of a film of photochromic organic material that can comprise molecules of azobenzene, or of spyropyrane, or of stilbene, or of coumarin, or of fulgide, said illumination creating a surface grating in said film comprising scratches, the deformations of which are a function of the turbulence parameters; a step of acquisition of images comprising individual areas of structures linked to said scratches, more or less reduced and representative of the turbulence parameters of said medium; a step of processing of said images that makes it possible to assess the turbulence parameters of said medium. A device is also provided.

  • Birefringent micro-structured optical fiber for sensor application
    Patent number: 8958676
    Abstract: Fiber structure including a core and a cladding, a central microstructure having a first plurality of longitudinal holes and which is adapted for guiding optical radiation and for birefringence in the core. Also included is a side microstructure having a second plurality of longitudinal holes is provided, wherein the side microstructure partly surrounds the central microstructure and provides a predetermined mechanical anisotropy, a pressure responsive unit for converting an isotropic pressure force to birefringence changes on the core, a lateral force responsive unit for converting a directional pressure force to birefringence changes on the core, a temperature responsive unit for converting temperature to birefringence changes on the core, and a birefringence responsive unit for converting birefringence in the core to wavelength information.
