摘要： A process for the preparation of nanoscale particulate material is described comprising: (i) combining one or more functional material to be precipitated as nanoscale particles and one or more surface active material in a compressed CO2 phase with a density of at least 0.1 g/cc, where the functional material is substantially insoluble in the compressed CO2 in the absence of the surfactant, the surfactant comprises a compressed CO2-philic portion and a functional material-philic portion, and the compressed CO2 phase, functional material and surfactant interact to form an aggregated system having a continuous compressed CO2 phase and a plurality of aggregates comprising surfactant and functional material molecules of average diameter less than 10 nanometers dispersed therein; and (ii) rapidly depressurizing the compressed CO2 phase thereby precipitating the dispersed functional and surfactant materials in the form of composite particles of average diameter from 0.5 to less than 10 nanometers.

摘要： Authentication systems, apparatus, and methods authenticate an identification marking including a nanocrystalline material. One or more properties of the marking are ascertained to provide a measured profile. The measured profile is compared to at least one member of a closed set of reference profiles. Each reference profile has predetermined values of one or more properties. Each reference profile is unique within the set. At least one reference profile is characteristic of an indicator material in a nanocrystalline morphology and non-characteristic of the same indicator material in a bulk morphology.
