Abstract: The invention relates to a method for degassing a fluid comprising the following steps: supplying, at the inlet of a reactor comprising at least one microfluidic conduit, a fluid which can comprise at least one dissolved gas; then causing the fluid to flow through the reactor, the at least one conduit comprising a portion having a reduced hydraulic diameter, and the flow being set such that bubbles are generated by micro-cavitation, the fluid then comprising a liquid phase and a gas phase, then allowing the at least partial transfer of the at least one dissolved gas present in the fluid of the liquid phase to the gas phase; separating the liquid phase and the gas phase; and recovering the liquid phase to obtain the degassed fluid, the method not involving the application of ultrasound to the fluid between the step in which the fluid is supplied to the reactor and the step of separating the liquid phase and the gas phase.

Abstract: The invention relates to an exfoliation method according to which a fluid loaded with particles flows at a first flow rate into a first (2), and then into a second, section of a pipe (1), the first flow rate being suitable for generating shear stresses and cavitation bubbles in the fluid as it passes through the first section (2) of the pipe (1), the second section (3) having a hydraulic diameter suitable for bringing about an implosion of cavitation bubbles as soon as the fluid exits the first section (2) and flows into the second section (3), so that an exfoliation of the particles is brought about under the combined action of the shear stresses and a shock wave generated by the implosion of the cavitation bubbles, the first section (2) having a hydraulic diameter less than 300 ?m.

Abstract: Method of producing a wall, in particular a micro heat exchanger for semiconductor devices or microsystems, and micro heat exchanger, in which particles are embedded in a layer, some of which have a part anchored into a wall of said layer and a part projecting from this wall after removal of material.

Abstract: The device includes a first body (1) of superconducting material placed in the magnetic field to be measured, an arrangement (7) suitable for successively changing the temperature of this first body above and below its transition temperature, at a first frequency, so as to generate field variations in the vicinity of the body, and an arrangement for determining the field from these variations. The arrangement includes a second body (4) of superconducting material, placed in the vicinity of the first body (1), an optical fiber (8) suitable for changing the temperature of at least one portion of this second body, above and below its transition temperature, at a second frequency greater than the first frequency, in order to generate, in this second body, current variations proportional to the field variations. These current variations are then measured and the field is determined from these variations.
