AB  - Bismuth ferrite (BFO, BiFeO3), exhibiting both ferromagnetic and ferroelectric properties at room temperature, is one of the most researched multiferroic materials with a growing number of technological applications. In the present study, using a combined theoretical–experimental approach, we have investigated the influence of Ho-doping on the structural, electronic and magnetic properties of BFO. Synthesis and structural XRD characterization of Bi1−xHoxFeO3 (x = 0.02, 0.05, and 0.10) nanopowders have been completed. After structure prediction of Ho-doped BiFeO3 using bond valence calculations (BVC), six most favorable candidates were found: α-, β-, γ-, R-, T1, and T2. Furthermore, all structure candidates have been examined for different magnetic ordering using DFT calculations. The magnetic behavior of the synthesized materials was investigated using a SQUID magnetometer equipped with an oven. The plethora of magnetic and electronic properties of the Ho-doped BFO that our theoretical research predicted can open up rich possibilities for further investigation and eventual applications.

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  - 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)).

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  - Background and objectives: Blackberry is one of the most important berry fruits growing in Serbia. Crops and derived products are rich sources of many natural active compounds, which possess beneficial health effects. In particular, it is possible to point out the role of blackberry and its derived products in hyperglycemia prevention since it is a very common problem among the general population today. Blackberry wine is a product which could have significant beneficial health effects during moderate consumption. The aim of this study was to investigate the α-glucosidase inhibitory activity of blackberry wine and the contribution of some natural compounds to this activity. Methods: Fruit wines were produced through microvinification during controlled fermentation by using pure yeast strain culture. Samples were lyophilized and dissolved in DMSO. The inhibition of α-glucosidase was evaluated by using α-glucosidase and substrate solution, p-nitrophenyl α-Dglucopyranoside. The identification and quantification of some natural compounds was conducted by using UPLC TQ-MS/MS. Results: After lyophilization of the produced blackberry wine, all of the determinations were conducted in four samples. The results for the α-glucosidase inhibitory activity were in the range of 31.5–55.7 µg/mL. The control showed acarbose whit inhibitory activity of 75.3 µg/mL. Moreover, the estimated amount of epicatehin, catehin, chlorogenic, ellagic, and gallic acids and their contribution to the α-glucosidase inhibitory activity of the sample was from 1.7% to 7.7%. Discussion: The obtained results show that blackberry wine is a good inhibitor of α-glucosidase compared to acarbose. The presence of phenolic compounds in wine is due to its extraction from the skin and seeds of blackberry during alcoholic fermentation. Ethanol, which naturally occurs in wine, has a key role in this process. Fruit wine can be considered as a potential functional food. α-glucosidase activity depends on the synergistic and antagonistic effect of natural active compounds in fruit wine.

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).

abstract = "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.

AB  - Natural active principles are present in the fruit and during its processing pass into the final products. Among many natural active principles it is important to emphasize those which exhibit beneficial health effect on human organism. Beneficial health effect of those compounds is result of antioxidant properties. Wine is fruit derived product which is rich source of those compounds. The aim of this study was to investigate the influence of technological process on the phenolic profile, antioxidant properties and activity of antioxidant protection enzymes in vitro. Fruit wines were produced in controlled conditions during microvinifications. Phenolic profile of fruit wines were obtained by UPLC MS/MS, while antioxidant properties and enzymatic activity determined by spectrophotometric methods. The content of phenolic compounds in fruit wines was significant. It is important to highlight that different applied technology during the production, influenced on the content of above mentioned compounds. Flavonoids and phenolic acids were the most important. Also fruit wines showed ability to activate enzymes of antioxidant protection, which could be used in the protection against free radicals and prevention of oxidative stress.

AB  - The aim of this research was to investigate for the first-time photocatalytic degradation of methylene blue over SrGd2O4 powders co-doped with constant Er3+ (0.5 at.%) and different Yb3+ (1, 2.5 and 5 at.%) concentrations. Samples were successfully prepared via sol-gel assisted combustion method. They exhibit photoluminescence properties which are manifested as red emission at 661 nm (4F9/2 → 4I15/2) and two green emissions at 551 and 523 nm (4S3/2 → 4I15/2 and 2H11/2 → 4I15/2). X-ray Powder Diffraction pattern proved that all samples crystallize as a pure orthorhombic phase. Scanning electron microscopy was used for morphology characterization and it revealed the existence of porous agglomerated round-shaped particles. Energy dispersive X-ray spectroscopy showed the presence of dopant ions and even distribution of all constituting elements. To calculate the energy band gap, UV-VIS diffuse reflectance spectroscopy was performed and a value of 4.3 eV was obtained, as well as the four additional values from the bands at lower energies. Photocatalytic degradation of methylene blue was monitored using UV-VIS absorption spectroscopy. Obtained results were promising since after 4 h of exposure to the simulating Sun irradiation, more than 50% of the starting dye concentration was mineralized.

AB  - Unlike its ferroelectric and magnetic properties [1], the electrochemical behavior of bismuth ferrite, BiFeO3 (BFO) has received less attention [2]. In this contribution, BFO was hydrothermally synthesized [3] to be examined as an electrode for metal- ion aqueous rechargeable batteries. BFO powder was first investigated in terms of structural and surface properties using X-ray diffraction and Thermally-Programmed Desorption methods and then characterized in Li and Na- containing aqueous electrolytes using Cyclic Voltammetry and Chronopotentiometry. BFO was found to be inactive within the electrochemical potential window of the aqueous electrolyte. However, its ability to be electrochemically transformed, under deep cathodic polarization, results in an active phase composed of Bi- and Fe-based oxides, as confirmed by Fourier-transform infrared and Raman spectroscopy. The redox behavior of BFO-derived oxide electrode is compared in both Li and Na -based aqueous electrolytes and discussed in the context of tailoring electrochemical properties for safe and sustainable metal-ion batteries.

AB  - In this investigation, samples of SrGd2O4 doped with different Yb3+ (2, 4, 6 at.%) ions and constant Ho3+ (1 at.%) and Bi3+ (2 at.%) concentrations were prepared. The sol-gel method with glycine as a fuel and citric acid as a chelator was chosen for sample preparation. All samples were heated in the furnace for 1.5 h at 500 °C and then thermally treated for 2.5 h at 1000 °C. The pure orthorhombic lattice of SrGd2O4, space group Pnma, was revealed by X-ray diffraction (XRD) (JCPDS Card No.:01-072-6387). Transmission electron microscopy (TEM) discovered agglomerated clusters of spherical particles measuring around 150 nm in size. Including Bi3+ ions into the structure influenced the morphology of the sample showing fine packing of pyramidal-shaped nanoparticles. The uniform distribution of constitutive elements in the samples was confirmed by energy dispersive spectroscopy (EDS). Up-conversion emission properties were evaluated from photoluminescent emission spectra and intensity dependence on excitation power after excitation at 976 nm. Dominant green (550 nm), red (671 nm), and infrared (758 nm) 5F4, 5S2 → 5I8, 5F5 → 5I8, 5F4, 5S2 → 5I7 transition emissions, respectively, are detected in all samples. The sample co-doped with Bi3+ showed the most intense photoluminescent emission.

AB  - Magnesium (Mg) is an essential element in the human body primarily stored in bones. Mg ions have many potential benefits for bone tissue showing excellent osteogenic inductivity [1]. The aim of this study was to synthesize Mg substituted hydroxyapatite (Mg-HAP) for application in bone tissue engineering and to assess its behaviour in conditions mimicking physiological ones. Mg-HAP was synthesized using reflux method and its structural and morphological characterization was performed by XRD, FTIR and SEM. The changes in local structure and composition after irradiation and immersion in physiological solution and simulated fluid were assessed by electron paramagnetic resonance (EPR) spectroscopy. The results of EPR analysis pointed out that irradiation did not change the composition and structure of Mg-HAP. After immersion in model media (simulated body fluid and saline solution), the small amount of by-product of synthesis disappeared after 24 h and Mg-HAP remained the only phase. Also, the radical signals in EPR spectra faded away after 28 days in model media, showing that the structure and composition of Mg-HAP both went through a kind of stabilization in simulated physiological conditions. These results make the investigated Mg-HAP promising material for application in bone tissue engineering.

AB  - The fruit wines from blueberry were made by microvinification procedure. Wines were produced in the absence or presence of sugar and/or enzymatic preparation glycosidase (EPG). Selected phenolic acids were quantified using UPLC/MS-MS analysis. Total phenolic content (TPC) was determined by the Folin-Ciocalteu method. Also, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing ability of plasma (FRAP) methods were applied. The α-glucosidase inhibitory activity of blueberry wines was also investigated. Wines made with addition of sugar and EPG showed the best results. Phenolic profile and biological activity of blueberry wine depended from microvinification procedure which was used in the production.

AB  - The phenolic composition and antioxidant activity of wine and fermented pomace (FP) from Cabernet Sauvignon grapes harvested at three ripening stages were evaluated using LC-MS/MS and spectrophotometric analyses. An investigation of grey mold’s (Botrytis cinerea) influence on wine phenolic content modulation was conducted as well. Finally, the influence of the plant’s ripening stage on the dynamics of the phenolic compounds extracted from wine and FP obtained from fully ripe grapes was evaluated. In this study, the content of catechin, epicatechin, quercetin, and p-coumaric, gallic, and syringic acids was analyzed. Wine and FP were obtained after extended maceration during the spontaneous and inoculated fermentation of fully ripe grapes. When comparing the wine and FP obtained from véraison, fully ripe, and overripe grapes, catechin was the most abundant in wine (40.13 ± 3.25 mg/L) and quercetin in FP (10.96 ± 0.14 mg/kg). A decrease in analyzed phenolic compounds was noticed in wine produced from grapes affected by Botrytis cinerea, and the highest depletion was found for quercetin. The use of a winemaking technique that involved differing maceration periods and inoculation using yeasts as well as spontaneous fermentation significantly modulated the phenolic content of derived wines and FP. The dynamics of the phenolic compounds extracted into wine, evaluated using a principal component analysis (PCA), highlighted contents of catechin and epicatechin. After a decrease in maceration, the PCA revealed a notable content of gallic and syringic acids, as well as quercetin, in samples of FP. This study offers a perspective for future research and the development of functional food with a high content of phenolic compounds originating from red grape products, such as wine and fermented pomace.
