AB  - Porous anorthite (CaAl2Si2O8) ceramics, suitable for thermal insulation in buildings, were obtained using waste seashells as a source of CaO, kaolin as a source of Al2O3 and SiO2 and banana peel as a pore former. Changing the volume of banana peel as well as the processing temperature was found to be an effective approach to control the thermo-mechanical properties of the obtained anorthite ceramics. The sintering of powder compacts containing up to 30 wt% banana peel at temperatures ranging from 1100 to 1200 °C resulted in anorthite ceramics possessing up to 45% open porosity, a compressive strength between 13 and 92 MPa, a bulk density between 1.87 and 2.62 g/cm3 and thermal conductivity between 0.097 and 3.5 W/mK. It was shown that waste materials such as seashells and banana peel can be used to obtain cost-effective thermal insulation in buildings.

AB  - The possibility of using waste tailings produced by flotation in the lead and zinc mine of Grot, Serbia as a potential source of secondary mineral raw materials was examined. The aim of the research was primarily to carry out a detailed characterization in order to determine the dominant minerals, and, for the first time, to trace the changes occurring in the unit cells of the minerals present in that deposit. There was also a need to determine the exact proportions of the present mineral phases for their further application and utilization as natural resources in environmental protection. Samples were taken from three different sections of tailings: the crest of dam (JKB), outlet pipe of the flotation facility (JOF) and hydrocyclone overflow (JHC). Granulometric separation was performed to facilitate the extraction of certain minerals from waste. The results showed that all samples mainly contained quartz, clinochlore, calcite, albite, pyrite and biotite, but their ratios in each sample varied significantly. After characterization, samples were separated into different fractions and their mineralogical compositions were determined. Depending on the fraction, the mineralogical compositions also changed. Mineralogy and geochemical analysis indicate that waste tailings can be used as a secondary mineral raw materials source applicable in various industries.

AB  - The nanostructured powderwas synthesized by the glycine nitrate procedure (GNP) because it proved to be the most effective and simplest method suitable for controlling the composition and morphology of Co0.9Ho0.1MoO4. To prepare nanostructured Co0.9Ho0.1MoO4, metal nitrates, and glycine were mixed in appropriate stoichiometric ratios. For the preparation of the technologically important Co0.9Ho0.1MoO4, the combustion process has proven to be a promising method that achieves control of stoichiometry, homogeneity, and purity. The synthesized samples were examined by DTA, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, Spectroscopy, Field emission scanning electron microscopy (FESEM), and nitrogen adsorption method. The acquired nanopowder showed a tendency for agglomeration, inhomogeneous microstructure, and plate-like crystals. The photocatalytic activity of the obtained Co0.9Ho0.1MoO4nanopowders was evaluated by the photocatalytic degradation of crystal violet in an aqueous solution. After photocatalytic testing and all the above-mentioned characterizations, it was shown that these nanostructured materials represent promising solutions in photocatalytic processes toward green chemistry and sustainable development.

AB  - We studied the influence of Ag doping on the crystal structure and magnetic properties of CuO nanopowders. For the synthesis of nanoparticles of copper-silver oxides solid solutions with the composition Cu1-xAgxO (x=0.01–0.05), a self- propagating synthesis was applied at room temperature, during which a successful reaction between metal nitrate and sodium hydroxide occurred. Prepared powders were calcinated at 700 °C for 2 h. The diffraction pattern was recorded at room temperature and atmospheric pressure without of any re-heating of the sample. The Rietveld method for fitting refinement procedure was performed which showed the incorporation of Ag3+ ions in the CuO crystal lattice, where they substitute Cu2+ ions. SQUID magnetometer was used for investigation of magnetic behavior of synthesized materials in temperature interval 2–400 K. It is known that copper(II) oxide exhibits ferroelectricity driven by magnetic order at temperature as high as 230 K [1]. Multiferroic phase is present above the first order phase transition at TN1 = 213 K and exists up to the subsequent first order phase transition TN2 = 230 K [1,2]. It was shown that disorder in the form of impurities can stabilize the ferroelectric phase [2] this was our motivation to dope CuO with Ag in order to improve further its multiferroic properties. Compared with CuO, we observed small changes in magnetic properties in Cu1-xAgxO. The size and morphology of the particles were successfully determined by transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

AB  - Nano-crystalline Ca0.9Er0.1MnO3 oxide with a perovskite structure was synthesized by the sucrose nitrate procedure (SNP), with the help of sucrose, which plays the role of fuel and complexant. Other chemicals used are calcium nitrate tetrahydrate Ca(NO3)2×4H2O, manganese nitrate hydrate Mn(NO3)2×H2O, erbium nitrate pentahydrate Er(NO3)3×5H2O. Metal nitrates and sucrose were mixed in stoichiometric ratios, in order to obtain a perovskite with a crystalline structure. The resulting Ca0.9Er0.1MnO3 is calcined for 15 minutes in the temperature range from 800°C to 1000°C. Diffraction thermal analysis (DTA), X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and inductively coupled plasma ICP were used to characterize the obtained powder.

AB  - The present research demonstrates the synthesis and characterization of Ca0.9Er0.1MnO3 perovskite powder using the sucrose nitrate procedure (SNP) technique. The following substances were used to obtain this complex perovskite: sucrose C12H22O11, which has a dual role (complexant and fuel), and metal nitrates were used as oxidants - calcium nitrate tetrahydrate Ca(NO3)2×4H2O, manganese(II) nitrate hydrate Mn(NO3)2×H2O, erbium(III) nitrate pentahydrate Er(NO3)3×5H2O. Nanopowder was prepared by combining metal nitrates in their respective stoichiometric ratios. The synthesized Ca0.9Er0.1MnO3 powder was calcined in a temperature range of 800–1000 °C for a period of 15 min. The effects of calcination were characterized through different experimental techniques (differential thermal analysis (DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), and inductively coupled plasma (ICP)).

AB  - Nanometric size Co0.9Ho0.1MoO4 powder particles were obtained by applying glycine nitrate procedure (GNP). Powder properties have been studied by DTA, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, Spectroscopy, Field emission scanning electron microscopy (FESEM), and nitrogen adsorption method. The photocatalytic activity of acquiring Co0.9Ho0.1MoO4 nanopowders was estimated by the photocatalytic degradation of crystal violet in an aqueous solution. We present a simple and effective method for controlling the composition and morphology of Co0.9Ho0.1MoO4, as well as a possible new approach in inorganic synthesis methodology. During photocatalytic testing, the studied nanoparticle powder indicated a potentially promising solution in photocatalytic processes toward green chemistry and sustainable development.

AB  - Activated carbon is a highly porous and adsorptive material that is widely used for various applications such as wastewater treatment, air purification, and energy storage. Activated carbon can be produced from various raw materials, including biomass, which is a sustainable and renewable resource. The process of producing activated carbon from biomass involves two main steps: carbonization and activation. In the carbonization step, the biomass is heated in the absence of oxygen to convert it into carbon. The resulting carbonaceous material is then activated using a chemical or physical process to create a highly porous structure with a large surface area. One way to activate the carbonized biomass is to use bases as activators. Bases such as potassium hydroxide (KOH) and sodium hydroxide (NaOH) have been used as activators due to their ability to promote the development of micropores and mesopores in the carbon structure. Activated carbon was characterized by various techniques such as scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) analysis, Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analysis. These techniques provide information on the surface area, pore size distribution, functional groups, and crystal structure of activated carbon.

AB  - Thermo-chemical conversion via the pyrolysis of cigarette butt (CB) filters was successfully valorized and upcycled in the pre-carbonization and carbonization stages. The pre-carbonization stage (devolatilization) of the precursor material (cellulose acetate filter, r-CAcF) was analyzed by micro-scale experiments under non-isothermal conditions using TG-DTG-DTA and DSC techniques. The results of a detailed kinetic study showed that the decomposition of r-CAcF takes place via complex mechanisms, including consecutive reaction steps and two single-step reactions. Consecutive stages include the α-transition referred to as a cellulose polymorphic transformation (cellulose I → II) through crystallization mechanism changes, where a more thermodynamically ordered system was obtained. It was found that the transformation rate of cellulose I → II (‘cellulose regeneration’) is strongly affected by the presence of alkali metals and the deacetylation process. Two single-step reactions showed significant overlapping behavior, which involves a nucleation-controlled scission mechanism (producing levoglucosan, gaseous products, and abundant radicals) and hydrolytic decomposition of cellulose by catalytic cleavage of glycosidic bonds with the presence of an acidic catalyst. A macro-scale experiment showed that the operating temperature and heating rate had the most notable effects on the total surface area of the manufactured carbon. A substantial degree of mesoporosity with a median pore radius of 3.1695 nm was identified. The presence of macroporosity on the carbon surface and acidic surface functional groups was observed.

AB  - Iron(III) titanates are attracting rapidly growing interest as very promising candidates for applications in solar energy and optoelectronics because they contain earth-rich elements. Potentially, Fe2TiO5 is a thermoelectric material. We used a Vibrating Sample Magnetometer and Superconducting Quantum Interferometer Device Magnetometer to study the magnetic properties of the pseudobrookite material Fe2TiO5. The material was synthesized by the sol-gel method. The structural parameters of the synthesized samples were investigated by X-ray analysis. The diffractogram was refined with the help of Rietveld refinement on FullProf Suite. Temperature-dependent ZFC and FC magnetization was measured on SQUID for lower temperature down to 2 K and on VSM for higher temperatures up to 1000 K. A transition was observed at 815 K with a separation between the ZFC and FC curves. Parallelly the bifurcation in the isothermal hysteresis measurements indicates that the system exhibits dominant canted AFM (or weak FM) with a small amount of spin glass. The small value of the moment was also pointing towards the canted AFM ordering. The size and morphology of the particles was determined using transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

AB  - Cobalt molybdate is of importantce for the development of mobile telecommunication systems, such as mobile phones and high-quality microwave dielectric ceramics for high resonant frequency selectivity in microwave devices. Due to their special catalytic properties, cobalt molybdates have been used as catalysts in many chemical and petrochemical processes. The CoMoO4 nanoparticles ware synthetized in a simple, quick, and inexpensive way, by using a glycine nitrate procedure (GNP), with and without calcination at 450 °C [1], and investigated by applying the Briggs-Rauscher oscillatory reaction method [2]. The complex oscillatory BR reaction is sensitive to different insoluble analyte addition [3]. This feature of BR oscillatory reaction is used to investigate effect of different masses of GNP synthetized (with and without calcination at 450 °C) CoMoO4 samples on oscillatory dynamics. These two samples give the complete different effects in BR reaction. Obtained results strongly suggest that BR oscillatory reaction could be used for distinguishing these two samples, opening new direction in the investigation of ceramics materials.

AB  - Ca1-xGdxMnO3 (x = 0.05–0.20) nanostructured perovskites were successfully synthesized by modified glycine nitrate procedure (MGNP). Temperature intervals of sintering and phase transition during heating were revealed during dilatometric measurements. In order to determine the band gap values of the tested samples, ellipsometric measurements were performed in the UV-VIS spectral range. Decrease of band gap values with increase of Gd dopant content was attributed to n-type doping and upward shifting of the Fermi level in the conduction band. The investigation of the crystal structure and phase content of nanocrystalline Ca1- xGdxMnO3 powders was continued using micro-Raman spectroscopy. The electrical conductivity of Gd3+ doped sintered samples CaMnO3 as a function of temperature was measured by electrochemical impedance spectroscopy (EIS), in the temperature range of 400–700 °C. The corresponding activation energies of conductivity, measured in the investigated temperature range, were also discussed. The obtained research results showed that the highest hardness values of 7.58 GPa respectively, were achieved and that these nanostructured materials can be used as a high-density ceramic material for various industrial applications.

AB  - The main aim of this research is to show influence of different hydroxides, applied in carbon materials activation process on the electrochemical properties of activated carbon samples. The carbon material samples were prepared by hydrothermal treatment of sucrose and thermally activated using KOH, NaOH and LiOH by chemical activation method. The electrochemical properties of the obtained carbon material samples were examined by cyclic voltammetry and electrochemical impedance spectroscopy and correlated to their physicochemical properties. Investigated samples showed characteristic capacitor-like behavior. The best result of specific capacitance was obtained for the sample synthesized treated by KOH, while the increase in capacitance follows the arrangement of the growth of ionic radius of a metal from an alkali which is used for activation. Dependence on the type of hydroxide is due to differences in the radii of a metal. The alkalis with larger radii of metal produce wider pores and consequently the structure of a porous layer become more accessible and available to the charge transfer of capacitive response.

AB  - The examination of different raw materials as precursors for obtaining carbon materials is an important area of research due to the wide range of applications for carbon materials in various fields, including energy storage, catalysis, and electronic devices. Some of the commonly studied precursors for carbon materials include biomass, petroleum-based precursors, waste materials, natural materials. The selection of a precursor material depends on various factors, such as the intended application of the carbon material, the availability and cost of the precursor, and the properties of the resulting carbon material. Different precursors can result in carbon materials with varying structures, porosities, and surface chemistries, which can affect their properties and performance in different applications. In our work, we used cherry pits, sour cherry, vineyard peach pits, bean and pea husks. The properties of the initial precursors were tested and then they were treated physically and chemically at different temperatures and times. Correlation of the properties between the initial and final samples was made, as well as their potential application in relation to the obtained properties.

AB  - IQOS (I-Quit-Ordinary-Smoking) is a brand of heated tobacco. It is an alternative to traditional cigarettes, which involves heating tobacco rather than burning it. IQOS devices heat tobacco sticks, called HEETS or HeatSticks, to a temperature that is high enough to release nicotine and flavor, but not high enough to produce smoke. After consuming IQOS, we treated the remains of HEETS with pyrolysis at 800 degrees. In this way, we have protected the environment from pollution, and in addition, we have obtained carbon material, which further has various applications. The obtained final product was tested using different methods and based on the tested properties, it can be said that the material can potentially be used as an energy fuel, a supercapacitor, for the removal of organic compounds, a drug carrier, etc.

abstract = "IQOS (I-Quit-Ordinary-Smoking) is a brand of heated tobacco. It is an alternative to traditional cigarettes, which involves heating tobacco rather than burning it. IQOS devices heat tobacco sticks, called HEETS or HeatSticks, to a temperature that is high enough to release nicotine and flavor, but not high enough to produce smoke. After consuming IQOS, we treated the remains of HEETS with pyrolysis at 800 degrees. In this way, we have protected the environment from pollution, and in addition, we have obtained carbon material, which further has various applications. The obtained final product was tested using different methods and based on the tested properties, it can be said that the material can potentially be used as an energy fuel, a supercapacitor, for the removal of organic compounds, a drug carrier, etc.",

AB  - This study presents the characterization of waste vitreous enamel generated during the production process of heating devices in a factory in Southeast Europe. The sample was analyzed for chemical composition and concentrations of heavy metals using inductively coupled plasma optical emission spectroscopy (ICP-OES), while the mineralogical composition was determined using X-ray diffraction (XRD). The functional groups were recorded using DRIFT spectroscopy, and the morphological and microstructural properties were investigated using FESEM measurements. The results showed that the sample waste vitreous enamel contains high levels of heavy metals and must be classified as hazardous waste. Quartz was found to be the most represented mineral in the sample, while oxides of metals Sb, Fe, Ti, and Cu appeared in the form of supporting minerals. The DRIFT spectra showed the presence of silicates, organic materials, and OH groups in Ti(IV)-OH crystal structure. The FESEM analysis revealed different sizes of particles mainly with polygonal forms and pronounced edges corresponding mostly to the silica and the alumina. These findings can contribute to the development of strategies for the safe and sustainable management of waste vitreous enamel.

AB  - Activated carbons were successfully prepared using biowaste as a cheap and renewable raw material. Carbonization was performed on biomass first under nitrogen N2 atmosphere at 850ºC, and then were physical activated at different temperatures and different times of activation in atmosphere of carbon dioxide CO2. The influence of temperature and time of activation on physical, structural and morphological properties was studied by XRD, Raman spectroscopy, FTIR, BET, SEM analysis. The increase of temperature and activation time leads to the increase of specific surface area of carbon material. The charge storage ability was evaluated and systematically studied by means of Cyclic Voltammetry and Impedance method. The specific discharge capacitance of activate carbon materials in different pH–aqueous electrolytes (KOH, Na2SO4 and H2SO4), increases with the surface area, indicating that the double layer charging is controlled primarily by the development of surface porosity. The active carbon material with the most developed porosity maintained a high capacitance of 110.06 Fg-1 in KOH, 80.62 Fg-1 in Na2SO4 and 126.9 Fg-1 in H2SO4, at a very high scan rate of 300 mVs-1 . The micro/mesoporosity, depending on the type of aqueous electrolyte, was found to control not only the specific capacitance of materials, but also the hydrogen storage, C–H bonding and the relaxation time of adsorption.

AB  - Nanometric size Ca1-xGdxMnO3 (x = 0.05, 0.1, 0.15, 0.2) powder particles with perovskite-type structure were obtained by applying a modified glycine-nitrate procedure. [1, 2] All samples were investigated by X-ray diffraction (XRD), Infrared (IR) spectroscopy and EPR (electron paramagnetic resonance) measurements. In the perovskites with space group Pnma, octahedral tilting is most common and it is of great interest for geologists and materials science. It was experimentally observed how the amount of gadolinium dopants affects on the Mn-O bonds angles and distances, MnO6 octahedral tilting, the deformation due to the presence of Jahn-Teller distortion around the Mn3+ cation and relation between the structural and magnetic behavior. [3] The infrared reflection spectra of Ca1-xGdxMnO3 samples confirmed XRD results that Ca1-xGdxMnO3 nanopowders are of Pnma-1 structure and that the octahedral tilting is increased with Gd doping. The EPR spectra are in agreement with the expectation that EPR linewidth depend of Mn-O-Mn angle and that small octahedral tilting brought only a small change of the EPR linewidth.

AB  - Magnetoelectric multiferroics, showing simultaneous ferroelectric and ferromagnetic ordering, have aroused wide attention in recent years, because they offer a wide range of potential applications in data storage media, spintronics and multi-state memories. [1] The influence of Ho doping on the crystal structure of bismuth ferrite (BFO) nanopowders was investigated. Namely, BiFeO3 and Bi1- xHoxFeO3 ultrafine nanopowders were synthesized by the simple, low-cost and energy-saving hydrothermal method. The diffraction pattern was recorded at room temperature and atmospheric pressure in the absence of any re-heating of the sample. A fitting refinement procedure using the Rietveld method was performed which showed the incorporation of Ho3+ ions in the BiFeO3 crystal lattice, where they substitute Bi3+ ions. All the samples belong to R3c space group. In addition, theoretical investigation using bond valence calculations have been performed in order to mimic pure and Ho doped BiFeO3 compounds produced in the experiment. The optical properties of the material were examined by the spectroscopic ellipsometry method and the energy gap was found to be 2.71 eV. Transmission electron microscopy (TEM) and the scanning electron microscopy (SEM) was used to determine the particle size and morphology. Bi-based oxides will be electrochemically characterized in an aqueous electrolytes of sodium salts by means of Cyclic Voltammetry, to estimate their potential as sodium storage electrodes.

AB  - Bismuth ferrite (BiFeO3) is one of the most researched single-phase multiferroic materials.The Fe2 O 3 and Bi 2 O3 oxides were the starting materials for the synthesis of the single phase BiFeO3 . The preparation of BiFeO 3 was done by solid-state method with slight innovation: first, the oxides were activated separately, not together as usual, by milling in the ball mill and second, the 1% olein acid was added to Bi2 O3 as a surfactant before milling, to prevent its granulation. The adding of the oleic acid to Fe2 O 3 was not necessary, because it did not show granulation during milling. The activated Fe2 O 3 and Bi 2 O3 powders were characterized by granylometric analysis after milling in two steps for 4.5 h. The obtained particle sizes were confirmed by SEM micrographs. Finally, prepared oxide powders were mixed, homogenized and sintered. According to XRD pattern the final phase of Fe2 O 3 - Bi 2 O3 mixture sintered at 7900 C for 4 hours was rhombohedral phase of the R3c space group (JCPDS No. 86-1518) BiFeO3 with less than 4% of Bi-rich secondary phase of Bi 25FeO 40 .

The adding of the oleic acid to Fe2 O 3 was not necessary, because it did not show granulation during milling. The activated Fe2 O 3 and Bi 2 O3 powders were characterized by granylometric analysis after milling in two steps for 4.5 h. The obtained particle sizes were confirmed by SEM micrographs. Finally, prepared oxide powders were mixed, homogenized and sintered. According to XRD pattern the final phase of Fe2 O 3 - Bi 2 O3 mixture sintered at 7900 C for 4 hours was rhombohedral phase of the R3c space group (JCPDS No. 86-1518) BiFeO3 with less than 4% of Bi-rich secondary phase of Bi 25FeO 40 .",

AB  - Iron(III) titanates are composed of earth-abundant elements and are attracting rapidly growing interest as highly promising candidates for solar-energy as well as optoelectronics applications. Fe2TiO5 is generally recognized as potential thermoelectric material. We studied the magnetic properties of pseudobrookite material Fe2TiO5 by means of Vibrating Sample Magnetometer and Superconducting Quantum Interferometer Device Magnetometer. The material was synthesized by the sol-gel method and characterized by powder x-ray diffraction. The diffractogram was refined with the help of Rietveld refinement on FullProf Suite. Temperature-dependent ZFC and FC magnetization was measured on SQUID for lower temperature down to 2 K and on VSM for higher temperatures up to 1000 K. A transition was observed at 815 K with a separation between the ZFC and FC curves. Parallelly the bifurcation in the isothermal hysteresis measurements indicates that the system exhibits dominant canted AFM (or weak FM) with a small amount of spin glass. The small value of the moment was also pointing towards the canted AFM ordering. Transmission electron microscopy (TEM) and the scanning electron microscopy (SEM) were used to determine the particle size and morphology
