    摘要: The invention relates to a method for the tamper-proof storing of data in a bidirectionally linked blockchain structure. The method comprises the steps of creating an additional block Bi to extend the blockchain structure which comprises the data to be stored as payload data creating a bidirectional linking of the additional block Bi to a predefined number of preceding blocks, wherein creating the bidirectional linking comprises performing a backward linking of the additional block to the predefined number of preceding blocks and performing a forward linking of the predefined number of preceding blocks to the additional block.

    摘要: A process for the production of nanoparticles from a liquid mixture comprising at least one precursor and at least one solvent in a reactor with continuous through-flow comprises the steps of feeding at least one oxygen-containing gas inflow stream having a temperature into the at least one reactor, adding at least one fuel having a temperature to the oxygen-containing gas inflow stream, wherein the fuel and the oxygen-containing gas inflow stream form a homogeneous ignitable mixture having a temperature, wherein the temperature of the homogeneous ignitable mixture is above the autoignition temperature of the homogeneous ignitable mixture, introducing at least one precursor-solvent mixture into the homogeneous ignitable mixture; autoignition of the ignitable mixture of oxygen-containing gas and fuel after an ignition delay time to form a stabilized flame and reacting the precursor-solvent mixture in the stabilized flame to form nanoparticles from the metal salt precursor, removing the formed nanoparticles.

    摘要: Processes produce a compound material structure by producing a composite material which extends along an axis of elongation from carbon nanostructures anchored in a matrix of a first metal extending along the axis of elongation of the composite material. The processes comprise dividing the composite material into segments of the composite material, arranging the segments in a plane of a die matrix, filling free spaces in the die matrix with a filler material and subsequently sintering in the die matrix to form a compound material structure or squeeze casting in the die matrix, and exposing the carbon nanostructures of the composite material on at least one surface of the compound material structure such that the carbon nanostructures protrude out of this surface. Compound material structures and uses thereof as a heat conductor and/or a heat exchanger are also provided.
