“…The field emission scanning electron microscope images reveal that at 44.5 °C, the microstructure consists of porous and amorphous structures, whereas at the highest temperature (100 °C), the microstructure is characterized by crystalline structures, Figure . Similar results were discussed for the same films in a previous article . The results were related to the increase in sputtering energy as the substrate temperature increased.…”

“…The surface topography obtained via the atomic force microscope images indicate variation of the surface morphology with the substrate temperature, Figure . At the lowest temperature, the atomic force microscope (AFM) image consists of equally extensive bright and dark regions, indicating existence of porosity and ‘unclear’ surface structures . As the temperature increases, the surface structures (with well‐defined boundaries and grains) become distinct and it becomes possible to observe the grains of the film.…”

“…The experimental procedure and materials were earlier described in the previous article . Radiofrequency (RF) magnetron sputtering was used to deposit pure aluminum thin films (from 99.99 % purity aluminum target) on stainless steel substrates at different temperatures (44.5 °C, 60 °C, 80 °C, and 100 °C).…”

“…Through the fractal technique, information regarding lateral development of the films and multifractal characteristics of the surface structures can be obtained . The present article is an extension of our published work in which the microstructural and mechanical properties of aluminum thin films were extensively reported . However, the multifractal evaluation of the films at different substrate temperatures was not reported.…”

Micromorphology and nanoindentation properties of sputtered aluminum thin films are presented. The field emission scanning electron microscope, atomic force microscopy (AFM) and nanoindentation results are presented for films prepared at a substrate temperature ranging between 44.5°C and 100°C. A multifractal approach on the microstructure is presented to comprehend the micromorphology of the films. The roughness decreases, whereas fractal dimension increases as the temperature increases. The hardness and Young's modulus do not exhibit any predictable trend. Hardness and Young's modulus exhibit a linear relationship. Figure 7.

Gelatin/PCL bilayered particles loaded with Piper nigrum essential oil was synthesized aiming to access their morphological and surface dynamic patterns. Atomic force microscopy (AFM) was applied to investigate the 3D morphology and multifractal aspects of the particles surface. The AFM maps revealed spherical surfaces and well dispersed particles, besides a rougher surface on the loaded system. Minkowski functionals showed that shape of the rough peaks was similar in the unloaded and loaded systems; however, the presence of deep valleys on the loaded particles revealed their rougher pattern. Multifractal analysis revealed that unloaded and loaded particles presented multifractal behavior with different surface dynamics. The loaded surface presented a greater width of the multifractal spectrum and smaller difference of fractal dimensions, confirming their more vertically growing. These results can be useful in the development of novel polymeric‐based particles loaded with essential oil. Their unique surface dynamics can provide enhanced physical properties and performance in emerging biotechnological applications.
