AB  - Zirconium carbide ceramics were prepared by carbothermal reduction of ZrO2 and C that were mixed by high-energy ball milling. Powders were milled for times from 0 to 120 min in air. As milling time increased, the surface area of the powders increased, indicating significant particle size reduction. Milled powders were reacted at 1600 °C and then densified by spark plasma sintering at 2000 °C, which was sufficient to convert the starting powders to zirconium carbide. Unmilled powders did not reach full density. Milled powders reached full density, but ZrO2 impurities were found for specimens prepared from powders milled for 60 and 120 min. Microstructure analysis showed that grain size was less than 2 µm for ceramics produced from powder milled for 15 min. Based on densification onset temperature and impurity levels, a milling time of 15 min gives the best balance of particle size reduction to promote densification while minimizing impurity levels.

AB  - In the search for environmentally friendly materials with a wide range of properties, polymer composites have emerged as a promising alternative due to their multifunctional properties. This study focuses on the synthesis of composite materials consisting of four components: bacterial nanocellulose (BNC) modified with magnetic Fe3O4, and a mixture of BaTiO3 (BT) and polyvinylidene fluoride (PVDF). The BT powder was mechanically activated prior to mixing with PVDF. The influence of BT mechanical activation and BNC with magnetic particles on the PVDF matrix was investigated. The obtained composite films’ structural characteristics, morphology, and dielectric properties are presented. This research provides insights into the relationship between mechanical activation of the filler and structural and dielectric properties in the PVDF/BT/BNC/Fe3O4 system, creating the way for the development of materials with a wide range of diverse properties that support the concept of green technologies.

AB  - Due to the growing number of people infected with the new coronavirus globally, which weakens immunity, there has been an increase in bacterial infections. Hence, knowledge about simple and low-cost synthesis methods of materials with good structural and antimicrobial properties is of great importance. A material obtained through the combination of a nanoscale hydroxyapatite material (with good biocompatibility) and titanium dioxide (with good degradation properties of organic molecules) can absorb and decompose bacteria. In this investigation, three different synthesis routes used to prepare hydroxyapatite/titanium dioxide nanomaterials are examined. The morphology and semiquantitative chemical composition are characterized by scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX). The obtained materials’ phase and structural characterization are determined using the X-ray powder diffraction method (XRD). The crystallite sizes of the obtained materials are in the range of 8 nm to 15 nm. Based on XRD peak positions, the hexagonal hydroxyapatite phases are formed in all samples along with TiO2 anatase and rutile phases. According to SEM and TEM analyses, the morphology of the prepared samples differs depending on the synthesis route. The EDX analysis confirmed the presence of Ti, Ca, P, and O in the obtained materials. The IR spectroscopy verified the vibration bands characteristic for HAp and titanium. The investigated materials show excellent antimicrobial and photocatalytic properties.

AB  - MgTiO3 is a material often used in different types of high-frequency capacitors, temperature compensating capacitors, and chip capacitors, so the enhancement of this material is still the focus of many research groups due to its remarkable dielectric properties. Outstanding features can only be achieved when the ceramics are highly dense. Densification of magnesium titanate by Spark Plasma Sintering (SPS) was the aim of this work. Magnesium titanate ceramics were prepared by applying mechanical activation as the first step. Powders prepared in this way were SPS sintered, at 1200 °C with a heating rate of 100 °C/min. After reaching the desired temperature, a uniaxial pressure of 50 MPa was applied. The dwell time at this condition was 5 min, followed by cooling to room temperature at 5°C/min. X-ray diffraction was performed in order to establish the phase composition of milled powders and obtained ceramics. Differences between samples milled in various times intervals, as well as sintered ceramics were examined by means of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The presence of MgTiz0s phase was detected in XRD and was confirmed by EDS analysis for the non-milled ceramics. In the samples obtained from milled powders, no MgTi2O5 was detected in XRD patterns, but this phase was detected in EDS spectra in a lower amount. Dielectric measurements were performed at a wide range of frequencies, while the hardness of the SPS samples was measured at loads up to 10 N. The highest value of the hardness was obtained from powder milled for 15 min before SPS.

X-ray diffraction was performed in order to establish the phase composition of milled powders and obtained ceramics. Differences between samples milled in various times intervals, as well as sintered ceramics were examined by means of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The presence of MgTiz0s phase was detected in XRD and was confirmed by EDS analysis for the non-milled ceramics. In the samples obtained from milled powders, no MgTi2O5 was detected in XRD patterns, but this phase was detected in EDS spectra in a lower amount. Dielectric measurements were performed at a wide range of frequencies, while the hardness of the SPS samples was measured at loads up to 10 N. The highest value of the hardness was obtained from powder milled for 15 min before SPS.",

AB  - Development in many areas of engineering and technology are closely linked to the development of new or improvement of existing materials. Having in mind wide use of bacterial nanocellulose (BNC) in various areas of everyday life, from biomedicine, ecology to electronics, BNC-based composites are becoming widely used and attracting the attention of the scientific community. It is especially important to examine in detail the synthesis parameters that affect the changes in the crystal structure and morphology of the obtained composites, having in mind that these changes have a crucial influence on their final functional properties. In this paper, a composite material based on bacterial nanocellulose BNC (as the matrix) and ferromagnetic Fe3O4 was studied. BNC was obtained by the activity of acetic fermentation bacteria after 7 days of growth in a suitable medium. The research is aimed to optimization of the Fe3O4 precipitation conditions. It's especially considering the time interval of BNC films spend in the iron salt solution. The influence of the performed synthesis conditions was considered by the SEMEDS, FTIR and XRD methods.

AB  - Due to the growing number of people infected with the new corona virus in the world, there is an increase in bacterial infections, which weakens the immunity. New knowledge about simple and low cost synthesis methods of materials with good structural and antimicrobial properties are of great importance nowadays. Combination of bio ceramic Hydroxyapatite material with good biocompatible characteristics and Titanium dioxide material with good degradation properties of organic molecules when combine together has ability to absorb and decompose the bacteria. Hydroxyapatite/titanium dioxide nanomaterials have been prepared by tree different synthesis route. The morphology and semi quantitative chemical analysis were characterized by scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX). Phase and structural characterization of obtained materials were determined using X-ray powder diffraction method (XRD). The crystallite sizes of the obtained materials were evaluated in the average range from 8 nm to 15 nm. Due to phase analysis by XRD characterization the peak shows presence of anatase phase with hydroxyapatite. Based on XRD peaks positions the hexagonal hydroxyapatite phases are formed in every synthesis route with TiO2 anatase phase. The microstructural studies confirmed that the nanosized HAp coated in a different way with TiO2 depending on a synthesis route. EDX analysis confirmed presence of Ti, Ca, P, O in obtained materials. The IR spectroscopy confirmed vibrational bands characteristic for HAp and titanium with anatase phase. The investigated materials show satisfactory antimicrobial properties.

AB  - Cellulose, as the main constituent of plants, is the most common natural material that is widely used. Bacterial cellulose (BC) is a polymer of β-1,4-glucan chains, extracellularly attached to bacterial cells. It possesses the same structure as plant cellulose but its application has many advantages. BC has tinner threads, better crystallinity, mechanical strength and higher purity. By the means of micro- and nano-pores in the structure, it is possible to retain nano particles and enhance the application of obtained nanostructures. BC lacks antibacterial and antioxidative activity, conductivity and magnetic properties, which lowers the possibility of its application in biomedicine and electronics. To overcome previously mentioned deficiency, it is possible to apply bioactive polymers, nanomaterials or solid particles into the structure. High biocidal potential of TiO2 originates from its photocatalytic properties, and the generation of reactive oxygen species (ROS). At the first site of action, they cause cell membrane damage and afterwards, they attack intracellular components causing cell death. Hydroxyapatite (HAp) is capable to act synergistically with TiO2 and to accelerate its efficiency. Having in mind all characteristics of previously mentioned components, we have investigated the structure, morphology, mechanical properties and antimicrobial activity of advanced ceramics/polymer films. The influence of synthesis duration on BC structure, produced by Komagataeibacter xylinus species, was investigated. Thereafter, the possibility of TiO2/HAp ceramic nanocomposite application in BC was examined. The developed structures were analyzed by SEM and EDS analyzes, as well as XRD and FTIR spectroscopy. Mechanical properties were investigated as well.

AB  - Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared mixture was thermally processed at 300 oC for 6 h. Sintering at 1300 oC for 1 h resulted in a mixture of different phases, BaTiO3, BaFe12O19 and Ba12Ti28Fe15O84, which were confirmed by x-ray powder diffraction. A dense microstructure with a small volume fraction of closed porosity was indicated by the scanning electron microscopy, while a homogeneous distribution of Fe ions over BaTiO3 phase was visible from energy dispersive spectroscopy mapping. Doping of BaTiO3 with Fe2O3 resulted in formation of magnetic hexaferrite phases, as confirmed by dielectric measurements that showed a broadened maximum of the permittivity measured as a function of temperature.

AB  - Hybrid geopolymers represent a new class of composite materials formed by incorporating organic polymer into a geopolymer matrix. The properties of hybrid geopolymer depend on the addition of organic phase and the starting raw material composition (concentration of NaOH in alkaline activator, Si/Al mass ratio and solid/liquid mass ratio). In addition to these relevant parameters, this paper examines the synthesis conditions of these materials through the influence of the type, amount and manner of adding organic modifiers (commercial epoxy resins and 3- (methoxyl) propyl methacrylates) on forming the structure with significantly reduced pore distribution and decreased pore size, which exhibits good mechanical properties. The purpose of this research is to define the optimal conditions of the hybrid geopolymers' synthesis through the examination of relevant parameters. Expected improvement of mechanical properties was confirmed through values of compressive stength. Characterization of hybrid geopolymer composities was performed by XRD analysis, DRIFT spectroscopy and SEM analysis.

AB  - In a field of green chemistry, environmental protection and ecological conservation of the environment there are ways to come up with new and more advanced materials using on the one hand natural, recyceled or waste materials and on the other hand syntethic materials obtained by using green chemistry synthesis procedures. The aim of this paper was to synthesize and characterize Brushite-metakaolin-based geopolymer materials and to examine the possibility of using these materials in the fields of construction, cement industry, as well as in environmental protection as potential adsorbents. Initial materials which were used for geopolymer synthesis was Brushite (CaHPO4·2H2O) which was obtained by solutionprecipitation reaction form acetate solutions and Kaolinite clay from Rudovci deposit (Serbia). The obtained mixture powders were dissolved in a strong alcaline solution with addiction of water glass. Produced geopolymers was cast into mods and preserved for 28 days. The starting materials and the synthesized Brushite-metakaolin-based geopolymer material were examined using XRPD, FTIR SEM-EDS methods. The contact angle measurements were made to test hydrophilic and wettable properties of synthesized material.

AB  - In order to optimize process of geopolymerization, the investigation of thermodynamic parameters of alkali activators are important. The aim of this research was to investigate the influence of thermodynamic parameters (density, viscosity, refractive index and sound velocity) of alkaline activators on mechanical properties (compressive strength and hardness) of synthesized geopolymer samples. Geopolymers were synthetized by alkaline activation of metakaolin, having the density 2.524 g/cm3, using the activators at elevated temperature of 60 oC for two days. Based on the obtained results thermodynamic properties has been selected to predict the properties of materials. Four series of alkaline activators have been used. Activators remarked as AA1, AA2, AA3 and AA4 present the mixtures of Na2SiO3 and solutions of NaOH, of different molarities 2M, 4M, 6M and 8M respectively. The volume ratio of Na2SiO3 and aqueous solution of NaOH was the same for all samples. Densities, viscosities and refractive indices of alkaline activators were determined over the temperature range 15-60 oC of process of geopolymerizations. The values of density, viscosity and refractive index decrease with temperature increase over the investigated temperature range. Increasing molarity of alkali activator solutions, the sound velocity of activators is changed. For sample AA2 the values of sound velocity rises from room temperature to 45 °C and then begins to decrease while for the sample AA3 sound velocity grows until 30 °C and then starts to decrease with further increasing of temperature. Four series of geopolymer samples GP1 to GP4 were synthesiyed using the constant ratio of solid and liquid phase. FTIR, XRD, SEM-EDS methods were used for physicochemical further characterization of geopolymer samples.

AB  - There is potential use of red mud for synthesis of inorganic polymeric materials through a geopolymerization process as an alternative in the sectors of construction and building materials. By introducing of inorganic and organic modificators of microstructure (calcium hydroxide, bifunctional epoxy resins, or various types of alkoxylanes) during the geopolymer synthesis the enhanced values of ductility and strength can be obtained. Research was performed on alumosilicate material (red mud and metakaolin) and alkali activator raw mixture with defined quantity of modificator. The best sinthesys conditions were identified. Post-synthesis curing also play important role in obtaining of good-performing geopolymers. Characteristics of geopolymers were defined by measuring of compressive strength, N2-physisorption, as well as by SEM analysis, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). In addition the lower value of zeta potential was identified as the assisting factor for the specific structure domains formation (within the certain range of pH) accompanied by the high compressive strength.

AB  - Cesium aluminosilicate phases are of the great interest as possible host for Cs immobilization in radioactive waste management. The possibility to use zeolite as a host material for radioactive Cs immobilization was investigated. Cs-exchanged forms of clinoptilolite and 13X which were prepared by ion-exchange treatment were compacted. The powders compacts of exchanged zeolites were thermally treated at 1200 °C. The XRD analysis showed that Cs was successfully immobilized after heat treatment by formation of stable cesium-aluminosilicate ceramic forms. Thermal and mechanical properties of the sintered samples were investigated. From the perspective of these characteristics, Cs-exchanged zeolite (clinoptilolite and 13 X) can be considered as a potential material for safe waste disposal.

AB  - In the present work, remediation of lead-containing solution using raw and modified kaolinite has been presented. The micro and nanostructure of samples has been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). Laser diffraction and scattering (LDS), was analyzed by particle size analyzer based on laser diffraction and particle size distribution (PSD) was done. The degree of metal adsorption was evaluated analyzing the Pb(II) contaminated samples by inductively coupled plasma atomic emission spectrometry (micro- and nanostructure on immobilization efficiency correlCP AES). The results show the impact of immobilization efficiency and ation between micro- and nanostructure. The thermodynamic data (Delta HA degrees, Delta SA degrees, Delta GA degrees) are calculated from the temperature-dependent sorption isotherms. The results suggest sorption process of Pb(II) on kaolinite as spontaneous and endothermic.
