  • Patent number: 11802836
    Abstract: A process for detecting the sensitivity of one or more polymers and/or of one or more, mixtures of polymers to a compound, including the steps of exposing at least one lens-shaped micro-deposit, including the polymer(s) and/or the mixture(s) of polymers, to the compound, and detecting, by illuminating the surface of this micro-deposit, a change in the spatial distribution of the intensity of the light reflected or transmitted by this micro-deposit, linked to a variation in the dimensions and/or refractive index of this micro-deposit, under the effect of an interaction between the polymer(s) and/or the mixture(s) of polymers and the compound.
    Type: Grant
    Filed: June 1, 2018
    Date of Patent: October 31, 2023
    Assignees: Universite De Lille, Centre National De La Recherche Scientifique
    Inventors: Alexis Vlandas, Julien Wengler, Sebastien Lamant, Vincent Senez
  • Patent number: 11388808
    Abstract: The present invention relates to a plasma reactor and more specifically to an plasma microreactor comprising a support, made at least partially of a dielectric material, the support comprising a gas inlet, a liquid inlet, at least a fluid outlet, a liquid microchannel in the support, a gas channel, at least a ground electrode, at least a high voltage electrode, separated from the gas channel by the dielectric material of the support, wherein said ground electrode and said high voltage electrode are arranged on opposite sides of the gas channel so as to be able to create an electric field inside the gas channel, wherein the liquid microchannel and the gas channel are contiguous and at least an opening is arranged between the liquid microchannel and the gas channel so as to form a fluid channel and to cause the liquid flow contact the gas flow and wherein the liquid flow is retained within the liquid microchannel by capillarity action.
