Thermophysical properties of nanoobjects: Data classification and validity evaluation

The common problems of acquisition, classification, and certification of numerical data on the properties of nanoobjects have been considered. The peculiarity of their physical properties is shown to affect the preparation procedure of the informational stock which predates database creation. As an example, the data on the properties of carbon nanomodifications (nanotubes, graphene, etc.) are given. The key features of the data on nanostructures have been detected: frequent variations of the property nomenclature, size effect, and high level of data uncertainty. A procedure of the data certification is suggested, which includs information on the uncertainty and the quality indexes, estimating the completeness of the information on the subject of inquiry, the measurement/estimation method, and the reproducibility of results.
