AB  - Today in the age of advanced ceramic civilization, there are a variety of applications for modern ceramics materials with specific properties. Our up-to date research recognizes that ceramics have a fractal configuration nature on the basis of different phenomena. The key property of fractals is their scale-independence. The practical value is that the fractal objects’ interaction and energy is possible at any reasonable scale of magnitude, including the nanoscale and may be even below. This is a consequence of fractal scale independence. This brings us to the conclusion that properties of fractals are valid on any scale (macro, micro, or nano). We also analyzed these questions with experimental results obtained from a comet, here 67P, and also from ceramic grain and pore morphologies on the microstructure level. Fractality, as a scale-independent morphology, provides significant variety of opportunities, for example for energy storage. From the viewpoint of scaling, the relation between large and small in fractal analysis is very important. An ideal fractal can be magnified endlessly but natural morphologies cannot, what is the new light in materials sciences and space.

This area has been intensively researched due to the outstanding potential of this material, and this necessitated presenting some of the latest application related to engineering in this paper. A better insight of polycrystalline diamonds properties can be achieved by intensively researching the surface structure. Samples of nanocrystalline diamonds grown by the chemical vapor deposition method are analyzed and accordingly, the focus of the research was the surface parameters and their structure. It is observed that waviness and texture are unique for any direction, their values are almost the same for the chosen directions and they vary approximately from -0.2 nm to 0.4 nm. Analyses of the parameters allowed a more detailed insight into the morphology of the surfaces of polycrystalline films.

AB  - This paper is based on fundamental research to develop the interface structure around the grains and to control the layers between two grains, as a prospective media for high-level electronic parameters integrations. We performed the experiments based on nano-BaTiO3 powders with Y additives. All results on dielectric parameters on submicron level are the part of global values the same measured characteristics at the bulk samples. The original idea is to develop the new computing ways to network electronic parameters in thin layers between the grains on the way to get and to compare the values on the samples. Artificial neural networks are computing tools that map input-output data and could be applied on ceramic electronic parameters. These are developed in the manner signals are processed in biological neural networks. The signals are processed by using elements which represent artificial neurons, which have a simple function to process input signal, as well as adjustable parameter which has an influence to change output signal. The total network output presents the sum of a large number neurons outputs. This important research idea is to connect analysis results and neural networks. There is a great interest to connect all of these microcapacitances by neural network with the goal to compare the results in the standard bulk samples measurements frame and microelectronics parameters. The final result of the study was functional relation definition between consolidation parameters, voltage (U) and relative capacitance change, from the level of the bulk sample down to the grains boundaries.

AB  - Consolidation parameters have influence and can be used to control structure of BaTiO3 based materials. Microstructure and dielectric properties of Yb2O3 doped BaTiO3-ceramics, sintered from 1320 °C to 1380 °C have been investigated. The correlation between microstructure, capacity and dielectric properties of doped BaTiO3-ceramics, based on fractal geometry and micro-contact surfaces, has been developed. Using the fractal descriptors of the grains contact surface, the microstructure reconstruction constituents, as grains and pores shapes or intergranular contacts, has been successfully done. Obtained results indicated that fractal analysis contact surfaces descriptors of different shapes are very important for the prognosis of BaTiO3-ceramics microstructure and capacity and dielectric properties. The morphology of ceramics grains pointed out the validity of developing new structure analytical methods, based on different grains’ shape geometries. The grains contact structure based on Minkowski hull is presented as a new tool for BaTiO3-ceramics materials structure research. The materials properties prognosis are determined according to the correlations synthesis–structure–property, within Minkowski hull fractal frame. © 2019, © 2019 Taylor & Francis Group, LLC.

AB  - Improvement of novel materials could be very good development base for enhancement of new technologies. One of the most promising material of modern science is undoubtedly synthesized diamond. Because of variety of modern applications, the research in this area is becoming intensive. Utilization of this material made great step forward in many areas, beside the most known jewelry, also in producing microcomponents, in medical-surgery, as well as in high professional industry. These and others specific application of polycrystal diamonds, require permanently research and improvement of their properties. Although, the first synthesized diamond was created half a century ago using high pressure - high temperature (HPHT) method, diamonds created by chemical vapor deposition (CVD) method were much more convenient for application in so many areas. By applying CVD method, microcrystalline diamond (MCD) with grain size approximately 100 nm were created. Due to some disadvantages of MCD films, like values of hardness and Young’s modulus, new nanocrystalline (NCD) and ultra-nanocrystalline (UNCD) diamond materials were developed, with average grains size of 5-100 nm and 3-5 nm, respectively. The properties of polycrystalline diamonds can vary depending on the consolidation process like composition and pressure of applied gases, filament setup and reactor geometry. In that sense, changing the parameters of consolidation process, there is a possibility to change the microstructure of thin films and understanding its fundamentals. Also, fractal nature analysis could contribute to the revealing possibilities for improvement of polycrystalline diamond films. During carried out experiments, it was observed that there is the influence of grain size on thermal and electrical conductivity - when the thermal conductivity is increasing then electro conductivity is decreasing and opposite. Relation between the structures and final properties of synthetized diamonds can be achieved by explaining these phenomena based on fractal nature.

AB  - Grain size and morphology of BaTiO3-ceramics are very important characteristics in developing new dielectric devices. Samples with different additives were sintered at different temperatures and times. The microstructure of the samples was observed using scanning electron microscope (SEM). Experimental results indicated well-developed morphology of BaTiO3-ceramics from nano- to micro- scales, with the standard ceramics consolidation procedure. It is observed that the morphology of grains is the function of additives, sintering temperature and sintering time. However, image analysis of grain growth indicated that sintering temperature has a strong impact on the morphology and grain size of the samples in the temperature range 1240 °C to 1380 °C. Kinetic exponents and grain growth fractal dimensions were obtained with the collecting the parameters of same grain exposed to five magnifications by SEM imaging and using appropriate processing software for grain-shape fractal reconstruction. The main results in this paper established the relation between sintering consolidation process and fractal nature influence, as well as complex fractal correction on sintering temperature.

abstract = "Grain size and morphology of BaTiO3-ceramics are very important characteristics in developing new dielectric devices. Samples with different additives were sintered at different temperatures and times. The microstructure of the samples was observed using scanning electron microscope (SEM). Experimental results indicated well-developed morphology of BaTiO3-ceramics from nano- to micro- scales, with the standard ceramics consolidation procedure. It is observed that the morphology of grains is the function of additives, sintering temperature and sintering time. However, image analysis of grain growth indicated that sintering temperature has a strong impact on the morphology and grain size of the samples in the temperature range 1240 °C to 1380 °C. Kinetic exponents and grain growth fractal dimensions were obtained with the collecting the parameters of same grain exposed to five magnifications by SEM imaging and using appropriate processing software for grain-shape fractal reconstruction. The main results in this paper established the relation between sintering consolidation process and fractal nature influence, as well as complex fractal correction on sintering temperature.",

AB  - Synthetized diamonds have application in many areas, especially for electronic devices and components or mechanisms in watches, and medicine where they can be used for surgery knifes. Considering that for small grains is commonly known that atomic structure of grain size has strong impact on structural characteristics of synthetized diamonds, research of fractal nature of
microstructure of diamond films can have very important role in optimization of properties of these films. Regarding these processes, it was applied several characterization methods like SEM, EDS. These data were prepared and used as a source for fractal analysis application. Fractal theory can help in explanation of systems in which, at first sight, roles chaos. For that reason, fractal analysis can be applied on surface topology of synthesized diamonds and during the process of characterization of grains morphology. Thin films of diamonds, which are examined, are formed in chemical vapor deposition or CVD process. Aldo in some implementations is desirable to reduce the grain size, it can bring to the reducing the hardness of ultra-nanocrystalline or UNCD thin films. Because of that, it is very important to find the optimum between smooth surfaces from one side and hardness from the other side in order to create contact which is resistant to wear. Diameter of grain and their fractal geometry are very important microstructural characteristics. which have strong influence on all physical and chemical characteristics. In this paper, the goal is development of more accurate models which describe transportation and mechanical properties of polycrystalline diamonds.

AB  - The BaTiO3 ceramics applications based on electronic properties have very high gradient scientific and industrial-technological interests. Our scientific research has been based on nano BaTiO3 with MOD-Y salts and also on Y2O3. The samples have been consolidated at sintering interval 1200–1350 °C. We demonstrate the new frontiers for different electronic properties between the layers of BaTiO3 grains. As a research target we had GB composite, Nano size metal oxide dispersions, ACDC safety capacitance, nano scale grain boundary control, capacitance, GB control mobility in DC BS operation voltage. We applied all related characterizations and especially SEM. Fractal nature characterization and corrections include influences grains and pores surface and Brownian motions of particles. We established relation with all of this characteristics and temperature. Throw this experiments and results and fractals characterization, we opened new perspectives for higher electronic properties integrations between the grains and practically established the control within the processing, morphological structures and designing the properties. This is very important, new approach towards further miniaturization-fractal miniaturization and related, advanced technologies.

AB  - Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. The possibility to deposit polycrystalline diamond films via chemical vapor deposition (CVD) methods on large areas and on a large variety of substrates is posing numerous scientific challenges but also enables relevant industrial applications. Especially for small grain sizes, the grain’s misorientation and consequently the atomic structure of grain boundaries plays a significant role on transport properties and mechanical properties. Hence, the size and shape of the crystallites of poly- and nanocrystalline diamond films are one important key to optimize film properties for their specific applications. Fractal theory helps to find and define order in systems where disorder seems to prevail. Therefore, we apply fractal geometry analysis to characterize the grain morphology and surface topology of CVD grown diamond films. © 2018 Author(s).

Also, the investigation of the most valuable characteristics is the aim of permanently exploring. The thermal conductivity of synthesized diamonds research is very important, and because of that, the knowledge of the thermal conductivity properties is a basic point for completely understanding the synthesized diamonds phenomena. The experimental procedure confirmed interesting results regarding thermal conductivity. Investigation of the influence of different inputs on the synthesized diamonds process is of high importance. Due to the fact that the dimensions of the grain size have an impact on thermal conductivity, and that they are very small in deposited films of synthesized diamonds, the investigation of their fractal nature could lead to the further explanation of phenomena. The goal of this paper is basic analysis of what is the influence on thermal conductivity in the light of fractal nature materials properties.

Such structure can be applied in various areas, like medicine, electronics, micromechanical systems, microelectromechanical systems – MEMS and many others. For these and many other applications, one of the most important feature is the electrical conductivity. Although the natural diamond is an excellent insulator, synthesized diamonds show different behavior. The exploring of this feature is a complex area with a strong convolution between grain size and sp2 bond ing effect. The optimization of the synthesized diamond properties requires the revealing of the size and the shape of the created crystallites. Due to the size of grains being significantly reduced, the fractal theory can help in analysis of the grain morphology and especially of electrical conductivity.

AB  - Excellent mechanical, optical and thermal properties of diamonds are the advantages for which they are used in many areas and thus in the industrial as well. Considering that natural diamonds are rare and expensive, in order to overcome that, production of synthesized diamonds is a good solution. Hence, investigation of alternative producing methods led to discovery of commercially available chemical vapor deposition – CVD method. Using this method led to creation of microcrystalline diamond (MCD) with grain size larger than 100 nm. Because of some disadvantages of this synthesized diamond, new nanocrystalline (NCD) and ultra-nanocrystalline (UNCD) diamond materials were developed, with average size of grains ranging 5-100 nm and 3-5 nm, respectively. Reactor geometry, filament setup and gas phase conditions are also very important parameters for diamonds growth on silicon wafers, in addition to the mixture composition and pressure of applied gases. The goal of the paper is to present the relation of microstructure and diverse consolidation methods.

The influence of relation between the structures and final properties of synthetized diamonds can be achieved by explaining these phenomena based on fractal nature. The aim of the investigation is the establishing thermal and electrical conductivity relation phenomena within fractal nature synthesized diamonds frontiers.",

AB  - The development of new technologies is very often based on improvement of novel materials and the features of the existing ones as well as their application. Considering that the synthetic diamonds are one of the most appealing areas of modern materials science and its modern applications, the research in this area is becoming more intensive. Therefore, in this paper, an overview of the basic properties of natural and synthesized diamonds is firstly presented followed by the method of forming and parameters that affect the final properties of polycrystalline diamonds. The first method which was used for obtaining synthesized diamonds was HPHT (high pressure high temperature) method, by which were produced diamonds very similar to the natural ones. However, CVD (chemical vapor deposition) method for obtaining polycrystalline diamond films was more promising. By applying this method microcrystalline diamond (MCD) with grain size larger than 100 nm were created. Considering that there were some disadvantages of MCD, new nanocrystalline (NCD) and ultra-nanocrystalline (UNCD) diamond materials were developed, which average size of grains were 5-100 nm as well as 3-5 nm. Depending on the consolidation process (composition and pressure of applied gases, filament setup and reactor geometry) the properties of polycrystalline diamonds can vary. Detailed analysis of these materials nature can be additionally obtained by application of the fractal analysis which is presented in this paper.
