| In this paper some of the data obtained subsequently to the conclusion of the project called "New high-quality mined nanomaterials mass produced for plastic and wood-plastic nanocomposites"1 are described. The aim of this project was to investigate the release of nanoparticles extracted during the mining process, which are functionalized to improve the properties of materials for different industrial uses. The release of these particles might cause adverse health effects mainly in developing countries, where the waste produced by these materials is not a sustainably managed, and it is indiscriminately used in burning brick ovens, among others. Our participation in the project was to identify whether there was release of nanoparticles in the thermal and mechanical processes of the production. The present study describes some preliminary results of a new approach that aims to develop a method by which the structure of the surfaces of the fine particles can be defined and classified by a specific parameter called Hurst coefficient (H) which is directly related to the fractal dimension. The proposed method uses the fractional Brownian motion (fBm) analysis to parameterize the microscopic images recorded from the released particles with various components. At the microscopic scale, the particles were segmented from the background and the values of H of the selected regions in the images were determined. The range of H values was between 0.27 and 0.60, depending the fluctuation of the surface of the particle. Finally, some future work related applications of using the proposed methodology are discussed. | |
