  • Patent number: 12251451
    Abstract: The present description relates to an injectable emulsion comprising an amphiphilic compound, a first phase comprising droplets including at least one perfluorocarbon compound and a second phase, which is aqueous. The droplets have a diameter d4,3 of between 0.5 pm and 5.5 pm, and the at least one perfluorocarbon compound has a boiling point above 100° C. The present description also relates to methods comprising administering such an injectable emulsion in, for example, ultrasound ablation surgery (FIG. 3).

  • Publication number: 20240224881
    Abstract: A mobile light exposure device that delivers light pulses to a plant material has a first emission module that has at least one light treatment panel configured to emit one or more light pulses; has a second module configured for adjusting and/or switching on an optical power density of the light treatment panel and optionally a temperature of the light treatment panel; and has a locomotive means for moving the mobile light exposure device. In operation, the mobile light exposure device attenuates impacts on plant material associated with abiotic stresses, such as stresses associated with edaphic, climatic and/or chemical factors.

  • Patent number: 12016957
    Abstract: The present description relates to a method for extracting at least one substance of interest, the method comprising the following steps: —providing an admixture comprising water, a source comprising the at least one substance of interest or at least one precursor thereof, at least one surfactant and at least one lipophilic compound; —the emulsification of the admixture, leading to the formation of an emulsion; wherein the emulsion comprises: —a continuous aqueous phase; and a discontinuous lipidic phase comprising the at least one lipophilic compound, the at least one surfactant and at least one substance of interest extracted from the source during the emulsification; wherein the method further comprises the addition of at least one cryoprotectant to the admixture and the lyophilization of the emulsion.

  • Publication number: 20220400619
    Abstract: A mobile light exposure device or improving the yield and quality of biological material has a first module for emitting one or more light pulses, which includes a light treatment panel whose surface area is between 0.01 m2 and 10 m2, a second module or adjusting the optical power density of the treatment panel and optionally adjusting the temperature of the panel, and a means of locomotion for moving the device at a speed of between 1 and 10 km/h. The optical power density of the panel is between 100 W/m2 and 10,000 W/m2, preferably between 300 W/m2 and 3,000 W/m2, and the light pulses delivered to the biological material are of identical or different wavelengths and of durations less than or equal to two seconds.
