Topographic characterization of canine teeth using atomic force microscopy images in nano-scale

The sputtered copper nanoparticles (Cu NPs) on amorphous hydrogenated carbon films (CuNPs@a-C:H) were deposited on a glass substrate by the codeposition method of radio-frequency (RF)-sputtering and RF-plasma-enhanced chemical vapor deposition methods. The thin films were synthesized in different deposition times of 10, 15, 20, and 25 min while other parameters were constant. Rutherford back scattering measurements specified the atomic content of the thin films while the localized surface plasmon resonance peak was extracted from the UV–visible spectra. To investigate surface images, an atomic force microscope in noncontact mode was used to give valuable information for the stereometric, fractal, and particle analyses. The surface topography was computed based on the ISO 25178–2:2012 standard and the Abbott-Firestone curves; polar graphs were plotted for additional statistical information on the surface microtexture. The autocorrelation function and three-dimensional (3-D) surface texture interpreted surface topography, anisotropy ratio, and functional properties which help optimize the thin film’s functional performance. The X-ray diffraction profile which was applied to investigate the crystalline structure confirmed copper as the major structural component with Cu(111) and Cu(002) peaks, the intensities of which were increased with the deposition time. Finally, particle analyses were applied to confirm the previously obtained results.

“…These analyses extract a lot of information about the topography and analyze the surface of thin films quantitatively (Nezafat et al, 2019a; Solaymani et al, 2021; Ţălu et al, 2018). The stereometric (Mozaffari et al, 2020; Sobola et al, 2017; Solaymani et al, 2020) data as well as multifractal (Fattahi et al, 2020; Ţălu et al, 2017; Ţălu et al, 2020) and fractal (Nezafat et al, 2019b; Ţălu et al, 2018) analysis are able to characterize the microtexture and particular morphological characteristics of the 3D surface. In this regard, AFM images and new image processing methods provide significant information about nanoscaled configuration and topographic features (Dalouji et al, 2019; Mahmoodi et al, 2018.…”

In the last decade, laser Ablation technique (Nd:YAG) has been considered as a perfect method for producing nanostructures with high purity. In the present study, Titanium diboride nanoparticles (TiB 2 NPs) have been deposited on Aluminum (Al) and their micromorphology and microstructural properties have been investigated. The synthesis of TiB 2 NPs has been carried out by the Laser Ablation technique (Nd:YAG) which has not been reported so far. Moreover, the effects of laser energy on improving the synthesis of TiB 2 NPs have been examined. In this regard, five samples of TiB 2 NPs were prepared by Laser Ablation method in different values of laser fluency in the range of 0.4-1.2 J/cm 2 . The structural properties of prepared nanoparticles were detected by grazing incidence X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray spectroscopy. The morphology of samples was also investigated by field effect scanning electron microscopy. The results demonstrate the formation of spherical nanoparticles in all samples. Based on the results of the GIXRD patterns, pulsed laser energy is an effective parameter for the size of ablated nanoparticles. As can be seen, increasing the energy of laser beam decreases the average size of nanoparticles from 79.41 to 4 nm. As the next step, the as-prepared nanoparticles were deposited on Aluminum substrate with electrophoretic deposition technique at constant applied voltage (30 Volt) and constant deposition time (30 min). The X-ray diffraction pattern of TiB 2 NPs deposited onto Al substrate confirmed the formation of the TiB 2 thin films on all Al substrates. Also, the roughness and average particle size of deposited films were measured by atomic force microscopy images and MountainsMap ® Premium software. Increasing the fluency of laser beam made the surface more irregular and the maximum value of fractal dimension and hence, the most irregular topography has been observed in the sample produced by maximum laser fluency. Research Highlights• Titanium diboride nanoparticles have been synthesized by the laser ablation technique.• The effects of laser energy on improving the synthesis of TiB 2 NPs have been investigated.
