AB  - Metals and metal oxides have subpar antibacterial activities compared to those of small-molecule antibiotics, yet there are hopes that with proper compositional and structural adjustments this gap might be bridged. In this study, titanium dioxide (TiO2) nanoparticles were mechanically activated and combined with particulate silver through simple reduction process elicited by UV irradiation and assisted with the ultrasound. The resulting powders in various combinations (Ag vs. no Ag, activated vs. non-activated) were characterized using a range of experimental techniques and assessed for their antibacterial activities. The preparation procedure presented in this work prevails over the disadvantages of many chemical routes, most critically by avoiding the use of toxic substances. The mechanical activation did not reduce the particle size or crystallinity of TiO2 nor did it consistently alter the bandgap, yet it enabled the doubling of the amount of silver incorporable into the material. Further, while both mechanical activation and the addition of silver in the amount not exceeding 0.5 wt% produced barely detectable structural changes in the material, they both augmented its antibacterial activity. The precursor TiO2 powder produced no inhibition zone against any of the four bacterial species tested, while the mechanical activation of TiO2 led to the formation of distinct inhibition zones against each of the four bacterial species tested. The addition of silver to activated TiO2 further widened the inhibition zones and it also imparted the antibacterial activity to non-activated TiO2. The boost in the antibacterial activity achieved by the short mechanical activation was of a similar magnitude as the boost obtained after the addition of silver. The antibacterial activity was not different for different species when no silver was added to the system. However, with the addition of silver, species selectivity was obtained, as the composites were more effective against the two Gram-negative species (Escherichia coli and Klebsiella pneumoniae) than against the two Gram-positive ones (Staphylococcus aureus and Bacillus subtilis). The antibacterial activity increased with the addition of silver in the broth assay, but it was mediocre compared to that detected in the agar assay, attesting to the poor dispersability of the powders and their best performance when the bacterial cells migrate to the composite surface than vice versa. The findings of this study give hope that with appropriate microstructural or compositional alterations, the antibacterial activity of metal oxide powders and inorganic materials in general can be made comparable to that of small-molecule antibiotics.

AB  - This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple mixing of acetate solutions of Ceand Sr(, with NaH2PO4 at room temperature, and the studied compositions were Ce1-xSrxPO4 (where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5). The disintegration of Sr in monazite structures in different sintering temperature ranges from 600°C to 1000°C was investigated. The X-ray diffraction was used to track the evolution of the phase composition with thermal treatment. The morphology of sintered ceramics was obtained by scanning electron microscopy and vibrational bands of selected spectra were observed using the FT-IR method. Relative geometric density of selected samples was evaluated. The most favorable conditions for obtaining high-temperature Ce, Sr phosphate-based ceramic material are reported.

AB  - To investigate the influence of spinel structure and sintering temperature on the functional properties of BaTiO3/NixZn1−xFe2O4 (x = 0, 0.5, 1), NiFe2O4, ZnFe2O4, and Ni0.5Zn0.5Fe2O4 were in situ prepared by thermal decomposition onto BaTiO3 surface from acetylacetonate precursors. As-prepared powders were additionally sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the detailed examination of phase composition and morphology. The magnetic, dielectric, and ferroelectric properties were investigated. The optimal phase composition in the BaTiO3/NiFe2O4 composite, sintered at 1150 °C, resulted in a wide frequency range stability. Additionally, particular phase composition indicates favorable properties such as low conductivity and ideal-like hysteresis loop behavior. The favorable properties of BaTiO3/NiFe2O4 make this particular composite an ideal material choice for further studies on applications of multi-ferroic devices.

X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the comprehensive investigation of phase composition and morphology. The magnetic, dielectric, and ferroelectric properties were performed in detail.

AB  - To investigate the effect of synthesis procedure and sintering temperature on the functional properties of perovskite/spinel ceramics, BaTiO3/CoFe2O4 composites were prepared by thermal decomposition, coprecipitation, and microemulsion method, and sintered at 1150°C and 1300°C. The phase composition and morphology of as-prepared powders as well as sintered ceramics were thoroughly examined by X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS). The dielectric and ferroelectric measurements were performed in detail. Generally, the samples sintered at 1300°C had better performances than those sintered at 1150°C. The composite synthesized by thermal decomposition and sintered at 1300 °C stands out among other prepared BaTiO3/CoFe2O4 ceramics, owing to high stability in the wide frequency range and low leakage currents. The obtained results indicate that such composite might be successfully applied as a functional multiferroic.
AB  - У циљу испитивања утицаја методе синтезе као и температуре синтеровања на функционална својства керамике перовскитно/спинелне структуре, синтетисани су BaTiO3/CoFe2O4 композити методама термалне декомпозиције, копреципитације и микроемулзије, а затим синтеровани на 1150 °C и 1300 °C. Фазни састав и морфологија синтетисаних узорака детаљно су испитани пре и после синтеровања помоћу рендгенске дифракције на праху (XRPD) и скенирајуће електронске микроскпије (SEM) спрегнуте са елекрон дисперзивном спектроскопијом (EDS). Изведена су опсежна испитивања како диелектричних, тако и фероелектричних својстава датих композита. У већини случајева узорци синтеровани на 1300 °C показали су боља својства од узорака синтерованих на 1150 °C. Композит синтетисан методом термалне декомпозиције и синтерован на 1300 °C издваја се од осталих синтетисаних BaTiO3/CoFe2O4 узорака захваљујући великој стабилносту у широком фреквентном опсегу и малим струјама цурења. Добијени резултати недвосмислено указују да истакнути композит може бити успешно примењен као функционални мултифероик.

AB  - Hydroxyapatite Ca10(PO4)6(OH)2 - HAp presents natural construction material for bones and teeth and therefore is considered biocompatible, and has various applications in fields such as biomedicine, drug delivery, and as a biomarker. Considering nanoceramics' high specific surface area and antimicrobial activity, they can be used as potential antimicrobial materials. Bacterial cellulose (BC) is a biopolymer that stands out in its biodegradability, biocompatibility, and high water retention capacity, but also lacks functional properties. The main goal of this study is to create a newly designed composite material with the functionalization of cellulose by hydroxyapatite with antimicrobial properties. Hydroxyapatite material was incorporated in wet cellulose during the precipitation synthesis reaction. Obtained BC-HAp material was structurally and phase investigated by the XRD method. The morphology of obtained material was done by SEM, and appropriate functional groups were determined by the FTIR method. According to antimicrobial results investigated composite is shown proper antimicrobial activity.

AB  - The convergence of nano-, bio-, and information technologies is based on the understanding of complex hierarchical structures and systems, as well as on the material unity at the nanoscale and on technology integration from that scale. A growing interest in these technologies is a result of their potential to provide solutions to numerous societal challenges, such as advanced healthcare, environmental remediation, sustainable development, and adoption of cyber-physical systems based on the Internet of Things and the Internet of Systems. Taking into account that hybrid nanomaterials possess extraordinary physical and chemical properties derived from their size in the nanoscale, the aim of this work is to present the connection between processing parameters and multifunctional properties of nano scale hybrid materials, focusing on the study of ceramic-polymer structures before they can be nano-engineered into functional devices. The unique functionality of these nanostructures has enabled their applications in numerous devices such as: micro and nano-electro-mechanical systems (MEMS/NEMS), sensors, microactuators, surface acoustic wave devices, polymer electrolyte membrane fuel cells, switches, thermistors, resonators and filters, electrooptic devices, etc. In this study special attention has been paid to their applications in the fields of electronics, biotechnology, environmental protection and remediation.

AB  - Radiation shielding is a crucial precautionary measure in decreasing the dose of exposure medical personnel experience. The physical dimensions of these shields, specifically thickness and shape, are dependent on the type of radiation, energy and specific radioactivity. Currently, the most common radiation shielding equipment is made of lead, tungsten or uranium. Although these heavy metals have favorable shielding properties against ionizing radiation, protective garments such as lead aprons are heavy to wear and can pose significant health risks. Taking this into account, the primary goal of this study is to understand the radiation shielding properties of lead-free polymer geopolymer-polyurethane based composites. The geopolymer was synthesized using an 80%-20% mixture of fly ash and a bio-polyol substrate which was subsequently homogenized using MDI44. As a result, 6 samples of the geopolymer-polyurethane based composites were fabricated of which 5 were 90%-10% compositions between the mixture and varying concentrations of BaSO4 and Bi2O3 respectively. The last sample consisted of the pure fly ash/bio-polyol mixture. XRF and ICP analysis was used to chemically characterize the fly ash. The composite structures were analyzed using XRD, while the microstructural morphology was investigated using SEM techniques. Utilizing an energy-dispersive x-ray spectrometer (EDS), elemental abundance and agglomerating behavior was analyzed for each composite variant. The X-ray attenuation measurements pointed out that the obtained composites have the potential for a design of lead-free protective clothing against X-ray shielding in medical applications.

AB  - Nanocrystalline CoFe2O4 has been synthesized by various synthesis methods. The obtained monodomain nanoparticles are similar in sizes (15.8-19 nm), but with different internal stresses, size distributions and cation inversion coefficients (0.51 - 0.90) due to different synthesis routes. The structure and cation distribution are investigated by XRD diffraction analysis, Raman and FIR spectroscopy. Measurement of magnetization, i.e. coercivity, enable the calculation of the anisotropy coefficient K1 = (3.6-5.12)·105 J cm-3, which is very high in cobalt ferrite. The anisotropy coefficient directly depends on the nanoparticle size. It has been shown that magnetization linearly depends on the cation inversion, except in the sample with the largest nanoparticles (19 nm), where the more regular crystal structure prevails and higher values of magnetization were obtained. The average magnetic moments at 300 K are: μFe = 3.6μB and μCo = 2.5μB. It is obvious that with small adjustments in the synthesis, desirable nanoparticle properties can be obtained.

AB  - ingle phase cobalt ferrite (CoFe2O4) with nanoparticles of similar sizes (15.7-19 nm) was obtained by different synthesis methods: coprecipitation, ultrasonically assisted coprecipitation, coprecipitation followed by mechanochemical treatment, microemulsion and microwave assisted hydrothermal synthesis. The obtained CoFe2O4 samples have been studied using a variety of characterization techniques: X-ray diffraction (XRD), Raman spectroscopy, far infrared (FIR) reflectivity and attenuated total reflectance (ATR) in combination with Fourier-transform infrared (FTIR) spectroscopy in mid IR spectra. Different methods of synthesis produced nanoparticles with different lattice constants, internal stresses and different cation inversion values. This is confirmed in the subtle changes in the Raman and IR spectra of different CoFe2O4 nano-powders. The Raman spectra of CoFe2O4 were compared with the spectra of other ferrites and some cubic oxide spinels in an attempt to evaluate the contribution of tetrahedral and octahedral oscillations in certain Raman modes.

AB  - To examine the influence of phase composition on the magnetic, dielectric, and ferroelectric
properties of perovskite/spinel composites, NiFe2O4, ZnFe2O4, and Ni0.5Zn0.5Fe2O4 were in
situ prepared by thermal decomposition onto BaTiO3 surface. Acetylacetonate complexes were used as the precursors. The synthesized powders were compressed to pellets and additionally sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the comprehensive study of phase composition and morphology. The magnetic and electrical properties were performed in detail. The optimal phase composition was found in the BaTiO3/NiFe2O4 composite sintered at 1150 °C. This resulted in wide frequency range stability of relative dielectric constant. Furthermore, optimal phase composition in BaTiO3/NiFe2O4 led to suitable properties such as low conductivity and ideal-like hysteresis loop behavior. These functional properties of BaTiO3/NiFe2O4 make this composite a promising candidate for further studies on multiferroic properties.

AB  - The cobalt oxide (Co3O4) is a very attractive material for optoelectronic applications due to the intense absorption of visible light and p-type semiconducting properties. On the other hand, conventional synthesis methods for its preparation could be either time- and energy-consuming or relying on toxic chemicals. To address this issue, spinel Co3O4 nanoparticles were prepared by a simple, facile, and eco-friendly method of synthesis. Such method is based on the thermal decomposition of hexaaquacobalt(II) D-camphor10-sulfonate at 900 °C. This synthesis route avoids the use of toxic organic solvents which overcomes the disadvantages of many combustion methods. In order to assess the potential use of synthesized powder, the characterization methods were performed in detail. The purity and semiconducting properties of the Co3O4 were confirmed by UV/Vis spectroscopy which indicated the presence of two band gaps (2.10 eV and 1.22 eV). A noteworthy improvement in the electron transfer kinetics with the addition of the prepared sample to the carbon-paste electrode led to an enhanced electrocatalytic performance. Such remarkable functional properties are suitable for a wide range of technological applications, open the way for the implementation of this preparation procedure for the synthesis of Co3O4 on a larger industrial scale.

AB  - The dielectric properties of nanocomposites based on isotactic polypropylene (iPP) and atactic polystyrene (aPS) obtained by novel, simple, and environmentally friendly treatment technique have been analyzed in this study. The best treatment conditions to obtain nanocomposites with embedded core-shell particles with enhanced dielectric properties were considered. Treatment of polymer matrices in water solution iron(II)-chloride had the most pronounced precipitation effect, that was directly related to the appearance of higher transition metal concentrations in the iPP and aPS matrices, in comparison to treatments in the other two transition metal salts, MnCl2 and NiCl2. Relative dielectric constant and loss tangent have been studied in the frequency range from 20 Hz to 9 MHz. Embedded core-shell nanoparticles (from 15 to 150 nm in diameter) in a very small amount (1.72E-8 mol/cm3 to 1.17E-5 mol/cm3) resulted in significant improvement (2.5% up to 9.1%) and stabilization of relative dielectric constant value toward higher frequencies and also lowering loss tangent in compare to starting polymer matrices. These properties indicate that materials obtained with the presented treatment technique can be applied as microelectronic packing and with further development of the method in order to obtain a higher concentration of metal ions as energy storage devices.

AB  - This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple mixing of acetate solutions of Ceand Sr(, with NaH2PO4 at room temperature, and the studied compositions were Ce1-xSrxPO4 (where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5). The disintegration of Sr in monazite structures in different sintering temperature ranges from 600°C to 1000°C was investigated. The X-ray diffraction was used to track the evolution of the phase composition with thermal treatment. The morphology of sintered ceramics was obtained by scanning electron microscopy and vibrational bands of selected spectra were observed using the FT-IR method. Relative geometric density of selected samples was evaluated. The most favorable conditions for obtaining high-temperature Ce, Sr phosphate-based ceramic material are reported.

За синтезу је коришћен метод припреме једноставним мешањем  раствора Ce(C2H3O2)3·xH2O), Sr(C2H3O2)2, и NaH2PO4 као прекурсора на собној  температури, а испитивани састави су Ce1-xSrxPO4 (где је к = 0 , 0,1, 0,2, 0,3, 0,4, 0,5).  Испитивана је дезинтеграција Sr у структурама моназита у различитим  температурним распонима синтеровања од 600 °C до 1000 °C. Дифракција рендгенских  зрака на праху (XRD) је коришћена за праћење еволуције фазног састава синтетисаних и  синтерованих узорака. Морфологија синтероване керамике испитивана је скенирајућом  електронском микроскопијом (СЕМ), а вибрациое траке одабраних спектра су испитане  ФТИР методом. Згушњавање и еволуција микроструктуре су одређене коришћењем  релативне геометријске густине одабраних узорака. Приказани су најповољнији услови за  добијање високотемпературног керамичког материјала на бази Ce, Sr фосфата.

AB  - Newly designed mesoporous brushite-metakaolin-based geopolymer materials were examined with an idea for using this material as a potential adsorbent for Pb(II) removal from aqueous solutions. As a starting component for geopolymer synthesis, a natural raw kaolinite clay with the
addition of 2 wt.%, 4 wt.%, 6 wt.%, 8 wt.%, and 10 wt.% of pure brushite was used. Phase, structural,morphological, and adsorption properties of newly synthesized mesoporous brushite-metakaolin geopolymer materials were examined in detail by the means of XRPD, FTIR, SEM-EDS, BET/BJH, and ICP-OES methods. The ICP-OES results showed that the synthesized material samples with 2 wt.%, 4 wt.%, and 6 wt.% of brushite possess significant adsorption properties and the mechanisms of the adsorption process can be attributed to chemisorption. The most notable result is that brushite-metakaolin-geopolymer with 2 wt.% of brushite have the best efficiency removal, more than 85% of Pb(II).

AB  - The emerging threat of bacterial resistance to antibiotics prompts the urgent search for biomaterials for the treatment of infectious disease. Here we report on the synthesis and characterization of a multiphasic nanocomposite comprising magnetic iron oxide and silver nanoparticles. The method of synthesis involved the combustion of a metalorganic complex and reduction of the silver ions that were exchanged and/or adsorbed on the surface of iron oxide. Different physical and chemical treatments coupled to the reduction process, including ultrasound and Lugol's iodine solution, respectively, homogenized the distribution of the silver nanoparticles on the iron oxide phase. Remarkably, using ascorbic acid as a reductant enhanced the magnetic properties of the material as a result of the reduction of the magnetic matrix alongside the silver cations. The treatment with ultrasound detached large amounts of silver from the iron oxide phase and resulted in the lowest amount of silver incorporated in the nanocomposite. Despite that, this treatment led to the highest antibacterial activity against both Gram-positive and Gram-negative strains, indicating that the homogeneity of the distribution of silver on the iron oxide matrix is a more important determinant of the antibacterial performance than the amount of silver incorporated in the material. At the same time, the treatment with Lugol's iodine equally increased the distribution homogeneity, but induced excessive ion exchange and crystal lattice substitutions, thereby adversely affecting the antibacterial performance. This has indicated that the mode of binding silver to iron oxide can compensate for the positive effects of homogeneous distribution with respect to the antibacterial performance.

AB  - The effect of Ca2+ amount and sintering temperature on mechanical properties of geopolymer-brushite (GPB) binders was investigated. Brushite and raw abandoned kaolinite clay thermally transformed into metakaolin were used for GPB synthesis. The complete phase and structural analyses were performed by X-ray powder diffraction, and Fourier transforms infrared spectroscopy (FT-IR). The pore-filling effect as a consequence of Ca2+ ions incorporation into the hybrid geopolymer networks improved the compressive strength. On the other hand, the chosen biscuit sintering at 800 and 900oC caused the phase transformation of brushite into calcium pyrophosphate, which negatively affected the compressive strength of such materials. The obtained results indicate that the usage of relatively high sintering temperatures is not always the necessary step for producing geopolymer-based types of cement with prominent mechanical properties.

AB  - Nickel ferrite nanoparticles were synthesized via thermal decomposition of β-diketonato complexes of nickel(II) and iron(III). The mechano-chemical activation of the complex precursors was used to ensure the increase in the reaction activity and consequently reduce thermal decomposition temperature. The prepared sample was thoroughly characterized by X-ray powder diffraction, FT-IR spectroscopy, scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS), and transmission electron microscopy (TEM). X-ray powder diffraction and FT-IR confirmed the spinel phase of the investigated powder. SEM and TEM revealed the ultrafine nature of nanosized polygonal particles, with a pronounced agglomeration effect. The capacity for electrocatalytic applications was examined using cyclic voltammetry (CV) and electrical impedance spectroscopy (EIS). Electrocatalytic measurements pointed out that the addition of 5% of nickel ferrite as a modifier to carbon paste electrode caused a current increase and a decrease of the EIS semicircle. Further increase in the amount of the modifier decreased heterogeneity of the electrode surface and served as excellent sensor for the detection of gallic acid in the concentration range from 1 to 10 µM with the detection limit of 0.27 µM. This unambiguously indicated the significant improvement in electrode transfer rate and better characteristics of the diffusion layer.

AB  - Barium titanate–nickel ferrite, barium titanate–zinc ferrite, and barium titanate–nickel-zinc ferrite composite powders prepared by thermal decomposition method were characterized by Raman spectroscopy, scanning electron microscopy (SEM), and X-Ray powder diffraction (XRPD). Obtained materials consisted of pure perovskite and spinel phases. Scanning electron microscopy analyses revealed that the morphology of investigated samples is not uniform, and aggregation of individual particles is a dominant process in all cases. Raman spectroscopy suggested that in the case of barium titanate–nickel ferrite, the coupling of two phases occurred and the core-shell structure was partially formed, while for barium titanate–zinc ferrite the coupling effect is less pronounced.

Scanning electron microscopy analyses revealed that the morphology of investigated samples is not uniform, and aggregation of individual particles is a dominant process in all cases. Raman spectroscopy suggested that in the case of barium titanate–nickel ferrite, the coupling of two phases occurred and the core-shell structure was partially formed, while for barium titanate–zinc ferrite the coupling effect is less pronounced.",

AB  - The CoFe2O4 nanoparticles were in situ synthesized on commercial BaTiO3 by thermal decomposition, coprecipitation, and microemulsion method. After initial preparation  procedures, the obtained powders were sintered at 1150 °C and 1300 °C in a pellet form. The bare powders, as well as sintered pellets, were thoroughly characterized by X-ray powder  diffraction and scanning electron microscopy coupled with electron dispersive spectroscopy.  The impedance spectroscopy, dielectric, and ferroelectric measurements were used to get  deeper insight into electrical properties of prepared materials. Better dielectric properties were  achieved for samples sintered at 1300 °C, irrespective of chosen synthetic route. The different  phase content obtained by three chosen synthetic procedures influenced different electrical properties of the investigated samples. The sample prepared in a microemulsion manner and  sintered at 1300 °C showed the best dielectric performances which can be explained by the  highest amount of barioferrite-like phase and the lowest amount of undesired  centrosymmetric P4/mmm BaTiO3 phase. Although well-defined electric hysteresis loops  were not achieved, the sample synthesized by thermal decomposition showed electrical  hysteresis most similar to conventional hysteresis loop of ferroelectric materials owing to highest amount of BaTiO3 phase.

AB  - Polymer nanocomposites are prepared by a simple and environmentally friendly technique. First, sheets of isotactic polypropylene (iPP) and atactic polystyrene (aPS) were prepared by compression molding with Servitec Polystat Press 200 T at 473.15 K and 3.0 MPa pressure followed by quenching in water at room temperature. The polymer sheets thus prepared were then immersed separately in three saturated salt water solutions (MnCl2, FeCl2, and NiCl2), at two temperatures (23ºC and 90ºC), and under influence of two DC electrical potentials (+4 kV, and ground potential). Count profiles and generated images of TOF – SIMS records have shown that higher temperature treatment (90ºC) and positive potential (+4kV) have given the highest count of iron ions and better distribution and dispersion of nanoparticles in polymer matrices. Also, the measured concentration of transition metals by ICP-OES confirmed higher concentrations of metals in nanocomposites obtained by these treatment conditions. It was stated that iron(II)-chloride had the highest concentration in iPP and aPS matrices in comparison to the other two transition salts. TEM micrographs showed spherically-shaped cores in the core-shell system and agglomerated particles of irregular shape. Encapsulation of iron cores prevented nanoparticles
from agglomeration. The cores of the investigated particles were probably iron oxides and/or hydroxides that occurred during the hydrolysis of iron salts in deionized water solution. Dielectric properties of obtained nanodielectrics were investigated. Relative dielectric constant and loss tangent has been studied in the frequency range from 20 Hz to 9 MHz. It was shown that adding the small amount of core-shell nanoparticles (from 15 nm to 150 nm in diameter) in a very small amount (1.72E-8 mol/cm3 to 1.17E-5 mol/cm3) are resulted in significant improvement and stabilization of relative dielectric constant value and also lowering loss tangent in compare to starting polymer matrices.These dielectric properties were marked as suitable for nanodielectric application for high speed and high dencity microelectronic packaging.

AB  - To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted hydrothermal syntheses were chosen for their preparation. The obtained materials had pure single-phase spinel structures. Scanning and transmission electron microscopy analyses revealed that the morphology of the samples is not uniform, and particle aggregation is a dominant process. Fourier transform infrared spectra and thermogravimetric analysis confirmed the presence of starch in all–coated samples. The unusually higher saturation magnetization of starch-coated samples than their as-prepared analogs, obtained by coprecipitation, ultrasonically assisted coprecipitation, and microwave-assisted hydrothermal methods, might be explained by the Ostwald ripening mechanism induced by the coating process. A decrease in magnetization was noticed for the starch-functionalized nanomaterials synthesized by mechanochemical and microemulsion methods, in comparison to their as-prepared analogs, i.e., the size distribution of such nanoparticles is narrow, and the average diameter of the grains is near critical for the Ostwald ripening process.

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.
