    摘要: The invention provides a method for continuously producing composite nanoparticles, the method comprising heating a precursor mixture with supercritical water, wherein the mixture contains a first compound capable of transitioning from a monoclinic to a tetragonal rutile crystal state; cooling the heated mixture to obtain core particles of a predetermined shape and size; encapsulating the core particle with a second precursor to create a core-shell construct; and encapsulating the construct with an organic material. Also provided is a device for continuously synthesizing composite nanoparticles, the device comprising a water supply and a precursor supply; a means for heating the water, a continuous flow hydrothermal reaction chamber adapted to receive the heated water and precursor, a means for chilling the heated water and precursor, and a capping agent supply positioned downstream of the reaction chamber. The invention also provides a nanocomposite particle comprising a core region, and a conformal organic overcoat.

    摘要: The invention relates to a reactor arrangement and to a method for decomposing objects of plastic-based composite materials into their individual constituents by way of a solvolysis using at least one reactor chamber in which the objects as exposed to a solvent in the supercritical state. The invention is characterized in that at least three pressure chambers located in series, a first load lock chamber, a reactor chamber adjoining the same, and a second load lock chamber adjoining the latter, which are each connected to each other via an actuatable partition which can be moved from an open position, in which two of the mutually adjacent pressure chambers are connected to each other, to a closed position, in which two of the mutually adjacent pressure chambers are fluidically, thermally and pressure-specifically isolated from each other. The reactor chamber is thermally coupled to a heating system and can be directly or indirectly fluidically connected via at least one first line to the first load lock chamber and can be connected to a first pressurizable feed line, via which solvent can be fed the reactor chamber.
