  • Publication number: 20110042611
    Abstract: An apparatus (10) and a method (200) for the manufacture of nanoparticles. The apparatus and the method allows for the nucleation and growth of nanoparticles at independent temperatures. The independent temperatures allow for the growth of nanoparticles in a controlled environment avoiding spontaneous nucleation and allowing particle sizes to be controlled and facilitating the manufacture of particles of a substantially uniform size. Furthermore the apparatus (10) allows for the manufacture of core-shell nanoparticles and core-shell-shell nanoparticles.

  • Publication number: 20100316554
    Abstract: The combination of at least one substantially unfunctionalised carbon surface, such as a fullerene, graphite or amorphous carbon, graphene or pre-aligned carbon nanotubes and at least semi-conducting nanoparticle, for example CdSe, CdTe, CdS, InP and/or ZnO or a metallic alloy nanoparticle is described wherein the at least one nanoparticle is directly attached to the substantially unfunctionalised carbon surface. A method for the manufacture of the nanoparticles is also described. This method comprises: —dissolving a cation source in a first organic solvent to produce a cation-containing medium; —adding a plurality of substantially unfunctionalised carbon surfaces to the cation-containing medium to form a cation-carbon mixture; —adding an anion-containing medium to the mixture of the cation-containing medium and carbon surfaces to form a cation-carbon-anion mixture, In the case of alloy nanoparticles, another cation medium is added instead.

  • Publication number: 20100316549
    Abstract: A method for the manufacture of a III-V compound in the form of nanoparticles, such as those used in semi-conductors. The reaction proceeds at atmospheric pressure in a reaction solution by the reaction of a III compound source and a V compound source. The reaction proceeds in solvent of high boiling point. The solvent contains a stabiliser and a base. The manufactured III-V compound is precipitated from the reaction solution, isolated, purified and analysed.

  • Patent number: 7241399
    Abstract: Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

    Abstract: The present invention relates to methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is narrower which renders a subsequent size-selected separation process superfluous.

  • Patent number: 5487501
    Abstract: A shock absorber component 7 is in the form of a flatly placeable strip, plate or mat and is especially for supporting the track of railroads. The shock absorber component 7 is placed between the superstructure 2 and the roadbed 1 of the track assembly. The shock absorber component 7 includes a core layer 8 having bonded rubber particles 12 and a cover layer 10 made of flexible material. The cover layer 10 surrounds this core layer 8. The rubber particles 12 of the core layer 8 are exclusively porous and the cover layer 10 is made of a compact rubber material. The cover layer 10 is vulcanized to the core layer 8.
