Abstract: Device including a catalytic system and an electromagnetic system, the catalytic system defining a catalysis chamber and including a catalyst of a reaction to generate a gas from a liquid, the catalyst being housed in the catalysis chamber, the electromagnetic system including a coil and a rod mobile relative to the coil, the rod being fixed to the catalytic system and including a magnet and a core, the electromagnetic system being configured to move the rod relative to the coil when an electrical current is passed through the coil, so as to dispose the catalytic system in an open position in which the catalysis chamber is in fluidic communication with the outside, the catalytic system being disposed in a closed position in which the catalysis chamber is hermetically closed in the absence of an electrical current through the coil.

Abstract: A catalytic device includes a hollow body, a piston housed in the hollow body, a catalyst of a gas generation reaction based on bringing a reactive liquid into contact with the catalyst, the catalyst being housed in a catalysis chamber, the piston and the hollow body defining a hermetic compression chamber for containing a compressible fluid, and being mobile relative to one another between a closed position in which the catalysis chamber is tight to the reactive liquid, and an open position for the entry of the reactive liquid into the catalysis chamber. The catalytic device is conformed to switch from the open position to the closed position, respectively from the closed position to the open position, when the compressible fluid is contained in the compression chamber and a force applied to the piston is greater than or equal to, respectively less than, a closure force.

Abstract: Useful apparatus for generating a gas, comprising an enclosure defining an internal space for containing a liquid capable of generating the gas by coming into contact with a catalyst, a catalytic system comprising first and second parts that together define a catalysis chamber for containing the catalyst and that are movable relative to each other between a closed position, in which the catalysis chamber is isolated from the internal space, and an open position, in which the catalysis chamber is in fluid communication with the internal space, so that, when the liquid and the catalyst are respectively contained in the internal space and in the catalysis chamber, in the open position, the liquid enters the catalysis chamber and the gas is generated by bringing the liquid into contact with the catalyst, an actuator connected to the catalytic system and configured to place the catalytic system in the open position and/or in the closed position, and a command unit for commanding the actuator.

Abstract: A dihydrogen generator (5) comprising a chamber (10), a reservoir (260) for containing a reagent and a catalytic system (15), the chamber being impervious to dihydrogen and defining an internal chamber space (45), the reservoir being housed in the internal chamber space and comprising a reservoir wall (270, 275) impervious to a liquid and permeable to dihydrogen, the catalytic system being disposed at least partly in the reservoir and comprising a catalyst (205) for the reaction that generates dihydrogen from the reagent, the chamber comprising a discharge valve (300) for withdrawing the dihydrogen from the internal chamber space, an injection valve (295) for injecting the liquid into the reservoir and a drain valve (460) for draining the liquid from the reservoir.

Abstract: A method for functionalizing the surface of a substrate, performed in a supercritical fluid medium, may include: (i) providing a substrate having labile hydrogen functions on the surface; (ii) bringing the substrate into contact, in a supercritical fluid, with at least one organic molecule carrying at least one blocked isocyanate function which can be activated by heating; and (iii) subjecting the whole to a temperature sufficient to bring about the release of the blocked isocyanate function carried by the molecule, and the covalent grafting of the molecule by reaction of the isocyanate function with a labile hydrogen function on the surface of the substrate.
