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  - This doctoral dissertation deals with detailed investigation of synthesis methods, coating and sinteringeffects on magnetic and electrical properties of spinel oxide-based nanomaterials for the applicationsin biomedical field. Part of the investigations included magnetic properties study of starch-coatedcobalt-ferrite (CoFe2O4) nanoparticles prepared by five different routes (coprecipitation,mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assistedhydrothermal syntheses). The synthesized materials were thoroughly characterized by standardtechniques. The general conclusion was that the way of coating alongside with chosen preparationmethod had a crucial role for magnetic properties. The magnetic measurements served as a goodplatform to monitor agglomeration and coating effects, which helped to choose materials with bestperformances for applications in magnetic resonance imaging (MRI). Another part of theinvestigations was devoted to the influence of synthetic method, phase composition and sinteringtemperature on BaTiO3/CoFe2O4 and BaTiO3/NixZn1-xFe2O4 electrical properties. The structure andmorphology of as-prepared and sintered samples were examined in detail. The optimalperovskite/spinel phase ratio is a key factor for prominent electrical properties. The electricalmeasurements performed on this type of composites might be a good screening test for choosingmagnetoelectric material for further investigations including usage in technology and/or medicine.

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  - 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  - 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.

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  - 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.

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.

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  - The light-transmitting measurements at the 655 nm wavelength were performed through starchcoated cobalt ferrite ferrofluids synthesized by well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted hydrothermal syntheses, exposed to an external magnetic field of 200–400 mT. The investigated samples can be divided into the two groups. The first is where the samples showed higher rate of agglomeration and sedimentation effects. The group of samples synthesized by microemulsion, microwave-assisted hydrothermal method, and mechanochemical method showed less pronounced rate of chain formation. Such measurements present good method for the preliminary selection of possible magnetic resonance imaging (MRI) contrast agents between differently synthesized ferrite suspensions.

AB  - Hematite (α-Fe2O3) nanoparticles have been synthesized by thermal decomposition of iron(III)acetylacetonate precursor. The structure and morphology of the resulting powder  were investigated by X-ray powder diffraction (XRPD), Fourier transformation IR (FTIR),  scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Hematite-loading with silver was conducted using the reduction of silver nitrate by ascorbic acid realized by three different synthetic procedures – simple reduction process, ultrasonically supported reduction, and reduction after pre-treatment of hematite in Lugol's iodine. All synthesized hematite/silver samples were characterized withSEM, supported by EDS maps. Silver content was determined by Inductively Coupled Plasma Optical Emission spectroscopy (ICP-OES). The development of Ag-doped hematite nanocomposites, hetero-structures containing Ag and magnetic iron oxide,is indispensable in orderto take advantage of Ag containing nanocomposites in the field of biomedicine.

AB  - The growing need to protect the environment and reuse abandoned raw materials is increasingly used in the construction industry to make  in addition to cementitious materials and geopolymer materials. Geopolymers are alkali-activated materials, in which the starting material is mainly some residual material such as: clay, fly ash, slag or red sludge [1,2]. There is growing need to create new binders which can replace portland cement and geopolymer materials are increasingly being used for this purpose. For geopolymerization reaction process high concentration basic solution with alkaline activators are adding and the process itself leads to modifications of the structures of the starting raw materials [1]. Due to growing needs to improve mechanical properties of geopolymer binders, different calcium sources can be added and one of them is brushite-dicalcium 
phosphate dihydrate [3]. The aim of this paper is synthesis and characterization of Brushite-metakaolin-based geopolymer material samples, with different percentages of pure Brushite material added. Brushite, was obtained by solution precipitation reaction from appropriate acetate salts solution, by green chemistry process. Raw kaolinite clay from the Rudovci deposit (Serbia) was used as Al and Si source for geopolymer binder production. Kaolinite was thermally treated at 750°C for three hours, to produce metakaolin and remove residual organic matter. In order to investigate the influence of calcium phosphate compound on mechanical and microstructural 
properties geopolymer material samples were synthesized using metakaolin mixed with activator solution prepared from sodium silicate and sodium hydroxide (6M) in relation 1,6 with addition of 2%, 4%, 6%, 8%, 10%, of pure brushite. Phase, structural, and microstructural characterisation were preformed in a mening of XRPD and SEM analysis. Difference between diffractograms of starting materials and Brushite-metakolin analogues indicates that geopolymerization process was successful in all samples. DRIFT technique was used to obtain characteristic vibrations of functional groups in obtained materials. The compressive strenghts of geopolymer binders containing brushite were in a range of 15-55 Mpa. The the highest hardness was achieved by a geopolymer with 10% of brushite.

Obtained nanopowders were characterized by X-ray powder diffraction, Fourier transform IR analysis, scanning electron microscopy, and Energy-dispersive X-ray spectroscopy. X-ray powder diffraction confirmed the formation of high purity NiO and α-Fe2O3 crystal phases. In the case of α-Fe2O3, about five times larger average crystallite size was obtained. Fourier transform IR spectra of synthesized materials showed characteristic peaks for NiO and α-Fe2O3 nanostructures. To visualize the morphology and the chemical composition of the final products Scanning electron microscopy and Energy-dispersive X-ray spectroscopy were performed. The thermogravimetric analysis was done for a better understanding of the general thermal behavior of precursor compounds. This easy-to-perform and fast preparation method opens a broad range of obtained materials’ usage, particularly due to its economic viability.

AB  - Cobalt-ferrite (CoFe2O4) and starch-coated CoFe2O4 nanoparticles were prepared by themechanochemical method and carefully chosen as adsorbents for Cr(VI) removal fromwastewater. The kinetic study, adsorption isotherms and influence of pH, contact time andinterfering ions were investigated to have deeper insight into adsorbent quality. UV/Visspectroscopy confirmed that the dominant adsorption mechanism is the electrostaticattraction at lower pH values. The study showed there was no significant change inadsorption efficiency for starch-coated nanoparticles. However, starch as a natural andbiocompatible compound can enhance nanoparticles water dispersibility. The advantage ofsuch materials is that saturation time does not exceed 20 minutes. Therefore, the as-preparedand starch-coated CoFe2O4 presents very efficient material for application in the field ofwater remediation.

The kinetic study, adsorption isotherms and influence of pH, contact time andinterfering ions were investigated to have deeper insight into adsorbent quality. UV/Visspectroscopy confirmed that the dominant adsorption mechanism is the electrostaticattraction at lower pH values. The study showed there was no significant change inadsorption efficiency for starch-coated nanoparticles. However, starch as a natural andbiocompatible compound can enhance nanoparticles water dispersibility. The advantage ofsuch materials is that saturation time does not exceed 20 minutes. Therefore, the as-preparedand starch-coated CoFe2O4 presents very efficient material for application in the field ofwater remediation.",
