“…Here, L is considered to be 3.0 μm with the sample rate of 3Mm −1 /2 = 30.12 μm −1 which specified the bandwidth limitation of PSD plots (Jakops, Duparre, & Truckenbrodt, ). On the other hand, the relationship between PSD as S(k) and frequency k is shown in the following equation and the slope of a Log S( k )‐Log k plot lead to fractal limitations (Solaymani, Ghaderi, & Nezafat, )

normalS ((), k) \propto k^{- β}

“…Moreover, lines I and II are the slopes of one and two log cycle of data, respectively, while the best fitted line is line III. Slope variation strongly depends on the data size, frequency, and spectral range (Solaymani et al, ). Therefore, in enamel out, increasing frequency lead to fractal dimension increase which are the same for interenamel, dentin, and cementum which are summarized in Tables , and , respectively.…”

Determining surface topography of different tissues of the molar tooth with novel analytical methods has opened new horizons in dental surface measurements which characterize tooth surface quality in dentistry. Studying surface topological measurements and comparing surface morphology of hard tissue of the molar tooth are the ultimate goals of the present study. Ten molar teeth have been chosen for investigating their surface characteristics through image processing techniques. The power spectral density (PSD) and fast Fourier transform algorithms of every molar tooth containing enamel, dentin, and cementum have determined that the characterization of surface profiles is possible. As can be seen, PSD along with fractal dimensions leads to good results for teeth surface topography. Moreover, PSD angular plot assures appropriate description of surface.

“…Recently, the physical properties of Tin + 1Xn (X = C, N; n = 1, 2, 3) 2D GL such as structural, electronic and optical properties have been investigated, all implicating a high potential for application in nano-technology [37]. Some theoretical and experimental works were focused on the electrical resistivity and conduction, elastic constants [38] and their application in the Li-ion batteries [39][40][41][42][43][44][45].…”

The Cr impurity effect on the optical properties of the Ti2N graphene-like materials: a DFT study

2019

The electronic and optical behaviors of the Ti 2 N graphene-like (GL) materials under the Cr impurity have been investigated based on DFT framework. The band structure and density of state (DOS) diagrams indicated that Ti 2 N:Cr GL has the magnetic metallic behavior about 3.2μ B . The density levels around the Fermi level in the band structure and the continuous DOS of under-Fermi to upper refer to the metallic nature of this compound. Adding Cr impurity has increased the metallic behavior so that the real and imaginary parts of dielectric functions have the red shift and their static values shifted to an infinite amount. Also, other optical parameters such as refraction, extinction and Eloss have been studied from the dielectric functions.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…8 On the other hand, in literature, there are different studies about characterization of microroughness parameters of thin films prepared by DC magnetron sputtering. [9][10][11][12] Many theoretical and experimental studies highlighted that the rough surface morphology of thin films can be concisely characterized by fractal 9,13,14 and multifractal [15][16][17][18][19] geometry, which may be directly applied for data obtained from the AFM.…”

This paper analyses the three-dimensional (3-D) surface morphology of thin films of Fe on Cu nanoparticles (NPs) synthesized by Direct-Current (DC) magnetron sputtering deposited on glass substrates. Four samples coated with copper and iron and deposited on the glass surface were used as research materials. Thin films were obtained by means of DC reactive magnetron sputtering method. The copper coating of each sample was 55 nm thick. In addition, the second, third and fourth samples had a coating of iron, with a thickness of 40 nm, 55 nm, and 70 nm, respectively.The sample surface images were obtained by using an atomic force microscope operating in a contactless mode.The 3-D of the surface samples was divided into motifs of significant peaks and pits using MountainsMap® Premium software, which uses the watershed segmentation algorithm. In addition, the highest and lowest points of motifs are localized. The parameters relating to all the segmented motifs consistent with ISO 25178-2: 2012 have been generated using the software. They allow for motif analysis, detection of essential characteristics and their characterization in terms of surface dimensions, volume, curvature, shape, structure etc. MountainsMap® Premium software makes it possible to perform 3-D segmentation of sample surface images and identify all sorts of motifs, such as peaks, pits or irregular shapes in correlation with the surface statistical parameters. The analysis of motifs helps to understand their functional role in the test surface, in order to evaluate the relation among the 3-D micro-textured surface.
