“…Common methods for calculating fractal dimension include the box counting method [ 19 ], correlation dimension method [ 20 ], Hurst index method [ 21 ], slit island method [ 22 ], yard stick method [ 23 ], area-perimeter method [ 24 ], Sierpiński carpet method [ 25 ], semi-variance method [ 26 ], and power spectral density [ 27 ] (PSD) method. The main methods to obtain object image are scanning electron microscope [ 28 ] (SEM), transmission electron microscope [ 29 ] (TEM), atomic force microscope [ 30 ] (AFM), and other imaging techniques. When the object is an image, after gray processing, binary processing is carried out [ 31 ].…”

The work is intended to summarize the recent progress in the work of fractal theory in packaging material to provide important insights into applied research on fractal in packaging materials. The fractal analysis methods employed for inorganic materials such as metal alloys and ceramics, polymers, and their composites are reviewed from the aspects of fractal feature extraction and fractal dimension calculation methods. Through the fractal dimension of packaging materials and the fractal in their preparation process, the relationship between the fractal characteristic parameters and the properties of packaging materials is discussed. The fractal analysis method can qualitatively and quantitatively characterize the fractal characteristics, microstructure, and properties of a large number of various types of packaging materials. The method of using fractal theory to probe the preparation and properties of packaging materials is universal; the relationship between the properties of packaging materials and fractal dimension will be a critical trend of fractal theory in the research on properties of packaging materials.

“…[8][9][10] Also, it is known that the 3D engineering surface can be divided into isotropic (Gaussian or non-Gaussian) or anisotropic textures. [11][12][13][14] In general, fractal approach in the surface morphology analysis makes use of the similarity law that governs the behavior of data series of height samples at different scale lengths which is benecial to reveal 3D nanoscale specic patterns and their special performances. 15 Here, for the rst time, we used carbon based supporting layer including reduced graphene oxide (rGO) nanosheets and CNTs with different mass ratios as substrate to deposit cobalt nanoakes for water oxidation reaction.…”

The presented study is aimed at analyzing the surface texture of amorphous hydrogenated carbon layers containing nickel nanoparticles (Ni-NPs@a-C:H) within their structure, which were deposited by Radio Frequency (RF) sputtering and RF-Plasma Enhanced Chemical Vapor Deposition (RF-PECVD) methods on glass substrates. Prepared films were then used as research material following their annealing at two different temperatures of 250°C and 350°C in an inert argon atmosphere. Series of height samples were taken with the help of atomic force microscopy (AFM) operating in a non-contact mode and examined in order to determine their fractal characteristics. Raw AFM data were first plane-fitted to remove the surface bow exhibiting the socalled residual surface, and then numerically processed to calculate the Areal Autocorrelation Function (AACF), which was later used to compute the Structure Function (SF). The log-log plots of the latter served for calculation of fractal properties of surfaces under investigation, including fractal dimension D, and pseudo-topothesy K. The analysis of 3-D surface texture helps to understand their essential characteristics and their implications as well as graphical models and their implementation in computer simulation.
