AB  - Colloidal stabilization of magnetic nanoparticles is one of the most important steps in the preparation of magnetic nanoparticles for potential biomedical applications. A special kind of magnetic nanoparticle are barium hexaferrite nanoplatelets (BSHF NPLs) with a hexagonal shape and a permanent magnetic moment. One strategy for the stabilization of BHF in aqueous media is to use coatings. In our research, we used an eco-friendly tannic acid, as a coating on BSHF NPLs. As-prepared BSHF NPLs coated with tannic acid were examined with transmission electron microscopy, infrared and UV-Vis spectroscopy, electro-kinetic measurements, and their room-temperature magnetic properties were measured. Stable colloids were tested in two biological complex media and antimicrobial properties of the material were examined. To enhance the antimicrobial properties of our material, we used tannic acid as a platform for the in-situ production of silver on BSHF NPLs. New hybrid material with silver also possesses magnetic properties and excellent antimicrobial activity against Escherichia coli and Staphylococcus aureus.

AB  - Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-source precursors at 450 °C in an air atmosphere. The mechanism and kinetics of thermal degradation of zinc-benzenepolycarboxylato complexes were analyzed under non-isothermal conditions in an air atmosphere. The results of X-ray powder diffraction and field emission scanning electron microscopy revealed hexagonal wurtzite structure of ZnO with an average crystallite size in the range of 39-47 nm and similar morphology. The band gap and the specific surface area of ZnO nanoparticles were determined using UV-Vis diffuse reflectance spectroscopy and the Brunauer, Emmett and Teller method, respectively. The photoluminescent, photocatalytic and antimicrobial properties of the ZnO nanoparticles were also examined. The best photocatalytic activity in the degradation of C. I. Reactive Orange 16 dye was observed for the ZnO powder where the crystallites form the smallest agglomerates. All ZnO nanoparticles showed excellent inhibitory effect against Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Escherichia coli.

AB  - Wooden cultural heritage serves as a very important source of information for historians and researchers. Also, it imposes an obligation on the science to keep this legacy for future generations in a proper condition. Among other techniques of conservation of wooden cultural heritage, a very suitable method is impregnation of the wood with the polymer, whereby the wood/polymer composites are formed. This paper describes the method of preparing the wood/polymer composites based on beechwood, using five different monomer systems. The method of lyophilization and subsequent polymerization by gamma radiation was used. After lyophilization and immersing in the monomer solutions, the wood samples were dried and irradiated with a dose of 25 kGy and different gamma irradiation dose rates. The weight of the samples before and after this procedure was measured. Also, changes in the mechanical properties of wood (compression test) before and after treatment were examined. We also examined the effect of radiation dose rate on polymerization. Based on the weight differences, dose rates and materials characterization we determined which of the monomer solution and dose rate are the most suitable for making beechwood/polymer composites.

AB  - Eu3+ activated LaPO4 phosphors were prepared by a high-temperature solid-state method and irradiated to different high-doses gamma-radiation in the 0-4 MGy range. No effects of high-doses of high-energy radiation on phosphor's morphology and structure were observed, as documented by electron microscopy and X-ray diffraction measurements. On the other hand, photoluminescence measurements showed that emission properties of phosphor were affected by gamma-radiation; changes in radiative properties being prominent for absorbed radiation doses up to 250 kGy after which no additional changes are observed. Judd-Ofelt analysis of emission spectra is performed to thoroughly investigate radiative properties of phosphors. Analysis showed that radiative transition probability of Eu3+ emission decreases while non-radiative probability increases upon gamma-irradiation. Quantum efficiency of emission is decreased from about 46% to 35% when Eu3+ doped LaPO4 powders are exposed to gamma-radiation of 250 kGy dose, showing no additional decrease for higher gamma-radiation doses.

AB  - Transition metal oxides are important materials that have found many applications,
as capacitors, sensors or in energy storage [1]. Synthesis of these compounds
has been realized by various methods, such as hydro(solvo)thermal synthesis,
precipitation, microwave synthesis or sol-gel synthesis [2]. Recently, the thermolysis
of coordination compounds as precursors has been considered as a new approach in
obtaining functional nanosized materials. [3]. In this way, by selecting the proper
precursor, it is possible to control the phase composition, morphology and particle
size of a resulting material [3]. The biphasic powder composed of ZnO (zincite) and ZnMn2O4 (hetaerolite), (I) has been
obtained by thermolysis of bimetallic complex [MnZn2(dipya)3(tpht)3(H2O)4]·2H2O
(dipya = 2,2’-dipyridylamine, tpht = dianion of 1,4-benzenedicarboxylic acid) at
450 °C during 1 h in air atmosphere. Scanning Electron Microscopy (SEM) was
used to investigate the morphology of I (Figure 1). It can be observed that the
morphology consists of deformed spherical grains of ZnO with an average diameter
of 67 nm and elliptical grains of hetaerolite whose average diameter and length
were 156 and 290 nm, respectively. The X-ray powder diffraction (XRPD) was
applied to investigate the structure of I. In Figure 2 two-phase Rietveld refinement pattern of I is presented (ZnO to ZnMn2O4 phase-ratio of 62:38 wt. %). The main
crystallographic data and Rietveld refinement parameters for ZnO phase are:
hexagonal, space group P63mc, a = 3.2574(1), c = 5.2175(2) Å, V = 47.945(3) Å3
; for
ZnMn2O4 phase are: tetragonal, space group I41/amd, a = 5.7299(3), c = 9.3000(8) Å,
V = 305.34(3) Å3
; Rwp = 4.80 %, Rp = 3.82 %, Rexp = 3.80 % and χ2
 = 1.5960. UVVis-NIR absorption spectrum was measured in order to investigate the direct band
gap (Eg) of I. Due to the existence of two phases in I, two different Eg values of
2.4 and 3.3 eV for ZnMn2O4 and ZnO phase, respectively, were determined using
Kubelka-Munk function. The mean size, polydispersity index (PDI) and zeta
potential of spherical grains were measured using Zetasizer Nano Series, Nano ZS.
The mean size was 418.6±53.1 nm while PDI value was found to be 0.354±0.099.
Relatively high values of PDI and low apostate value of zeta potential (–6.55 mV)
are indications of incipient instability of colloidal dispersion of I, probably due to the
formation of agglomerates [4, 5]. Photoluminescence measurements were carried
out at room temperature on Fluorolog-3 Model FL3-221 spectrofluorimeter system
upon excitation at 350 nm, in order to study the optical properties of I. This analysis
revealed one band centred at 422 nm in the blue region of the visible part of the
spectrum, which can possibly be associated with defects in the crystal structure of
the ZnO phase [6].

abstract = "Transition metal oxides are important materials that have found many applications,
as capacitors, sensors or in energy storage [1]. Synthesis of these compounds
has been realized by various methods, such as hydro(solvo)thermal synthesis,
precipitation, microwave synthesis or sol-gel synthesis [2]. Recently, the thermolysis
of coordination compounds as precursors has been considered as a new approach in
obtaining functional nanosized materials. [3]. In this way, by selecting the proper
precursor, it is possible to control the phase composition, morphology and particle
size of a resulting material [3]. The biphasic powder composed of ZnO (zincite) and ZnMn2O4 (hetaerolite), (I) has been
obtained by thermolysis of bimetallic complex [MnZn2(dipya)3(tpht)3(H2O)4]·2H2O
(dipya = 2,2’-dipyridylamine, tpht = dianion of 1,4-benzenedicarboxylic acid) at
450 °C during 1 h in air atmosphere. Scanning Electron Microscopy (SEM) was
used to investigate the morphology of I (Figure 1). It can be observed that the
morphology consists of deformed spherical grains of ZnO with an average diameter
of 67 nm and elliptical grains of hetaerolite whose average diameter and length
were 156 and 290 nm, respectively. The X-ray powder diffraction (XRPD) was
applied to investigate the structure of I. In Figure 2 two-phase Rietveld refinement pattern of I is presented (ZnO to ZnMn2O4 phase-ratio of 62:38 wt. %). The main
crystallographic data and Rietveld refinement parameters for ZnO phase are:
hexagonal, space group P63mc, a = 3.2574(1), c = 5.2175(2) Å, V = 47.945(3) Å3
; for
ZnMn2O4 phase are: tetragonal, space group I41/amd, a = 5.7299(3), c = 9.3000(8) Å,
V = 305.34(3) Å3
; Rwp = 4.80 %, Rp = 3.82 %, Rexp = 3.80 % and χ2
 = 1.5960. UVVis-NIR absorption spectrum was measured in order to investigate the direct band
gap (Eg) of I. Due to the existence of two phases in I, two different Eg values of
2.4 and 3.3 eV for ZnMn2O4 and ZnO phase, respectively, were determined using
Kubelka-Munk function. The mean size, polydispersity index (PDI) and zeta
potential of spherical grains were measured using Zetasizer Nano Series, Nano ZS.
The mean size was 418.6±53.1 nm while PDI value was found to be 0.354±0.099.
Relatively high values of PDI and low apostate value of zeta potential (–6.55 mV)
are indications of incipient instability of colloidal dispersion of I, probably due to the
formation of agglomerates [4, 5]. Photoluminescence measurements were carried
out at room temperature on Fluorolog-3 Model FL3-221 spectrofluorimeter system
upon excitation at 350 nm, in order to study the optical properties of I. This analysis
revealed one band centred at 422 nm in the blue region of the visible part of the
spectrum, which can possibly be associated with defects in the crystal structure of
the ZnO phase [6].",

AB  - Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 nanopowder as a starting material. We monitored the changes in the morphology of ceramic samples and their consolidation with additional thermal treatments at 650 degrees C and 1100 degrees C. The ceramics grain size remained in the sub-micron domain, even when elevated temperatures were used for annealing. The best results were obtained for the sample sintered at 1100 degrees C for 20 min, which had the smallest grain size, theoretical density, and the most intensive photoluminescence, along with the maximum hardness and appropriate fracture toughness. The Judd-Ofelt intensity parameters and branching ratios were calculated, taking into account the difference in the effective refractive index for the nanopowder and ceramic samples.

AB  - This study reports research related to different preparation methods and characterization of polymer nanocomposites for optical applications. The Eu-ion doped Gd2O3 nanophosphor powder with different nanoparticle content was embedded in the matrix of PMMA. Preparation was carried out by mixing molding (bulk), electrospinning (nanofibers) and solution casting (thin films) with neat particles and particles coated with AMEO silane. Among the pros and cons for proposed methods, the mixing molding enables to avoid solvent use while the best deagglomeration and nanoparticle distribution is gained using the electrospinning method. The results of dynamic mechanical analysis (DMA) and nanoindentation revealed that the storage modulus of the composites was higher than that of pure PMMA and increased with nanophosphor content. Surface modification of particles improved the mechanical properties of nanocomposites.

AB  - The results of a study related to the processing and characterization of poly(methyl methacrylate) (PMMA)-Y2O3 (Eu3+) nanocomposites are presented herein. The nanocomposite samples were prepared using a laboratory mixing molder with different contents of Eu-ion doped Y2O3 nanophosphor powder. The influence of particle content on the optical and dynamic mechanical properties of the nanocomposites was investigated. The intensity of the luminescence emission spectra increased as the nanophosphor content in the composite increased. The results of dynamic mechanical analysis revealed that the storage modulus, loss modulus and glass transition temperature (Tg) of the polymer composites increased with increasing content of the nanophosphor powder. The microhardness data also confirmed that the hardness number increased with nanoparticles concentration in the PMMA nanocomposites. The obtained results revealed a relatively linear relationship between Tg and the Vickers hardness.

Ipak urednici su se potrudili da koliko je to moguće stilski i pedagoški ujednače udžbenik, kako bi bio korisna literatura za sve studente diplomskih, master i doktorskih studija iz biomedicinskog inženjerstva u Srbiji i okruženju.",

AB  - A new approach to the two-level design and self-assembling of MexSiOy (Me = Gd, Y and Ca or their mixtures) nano-powders from SiO2 sols is described. The nanostructure design of various optical active materials based on different compounds of Me(x)Sio(y) is discussed. These particles were formed by the combination of hydrothermal synthesis and ultrasound spray pyrolysis. The morphology and structural design of the particles and sub-particles are defined by their synthesis procedure and processing parameters. The mean particle size and size distribution of all the MexSiOy based compounds were determined by SEM analysis. These results were compared with the particle diameter evaluated from the theoretical model of the breaking-up of capillary waves. For all the synthesized powders, the obtained results indicate the possibility of a rigorous design of the structure of the particles throughout their entire hierarchy.

AB  - U okviru ovog rada prikazano je korišćenje metode natkritičnog CO2 u pokušaju da se izvrši deaglomeracija i poboljša disperzija nano-SiO2 čestica. Površinska modifikacija čestica izvršena je korišćenjem γ-methacryloxy-propyltrimethoxy silana. Kao metoda za poređenje uzeta je konvencionalna metoda prevlačenja nano-SiO2. Rezultati ukazuju na znatno poboljšanje disperzije i deaglomeracije pri korišćenju natkritičnog CO2. Analiza TEM i DLS rezultata ukazuje da je došlo do smanjenja prosečne veličine aglomerata upotrebom silanskog promotora.

AB  - The supercritical CO2 method was used in order to perform deagglomeration and improve the dispersion of nano-SiO2 particles. γ-Met-hacryloxypropyltrimethoxysilane was used as the surface modification reagent. The conventional method for coating nano-SiO2 particles was used as the comparison method. Considerable improvement of the dispersion and deagglomeration was found using supercritical CO2. Analysis of the TEM micrographs and DLS results showed the reduction of the average size of the agglomerates with the silane coupling reagent. Thermogravimetric analysis (TGA) showed that the particles treated in super­critical CO2 were more thermally stable than particles treated by conventional method. Encapsulation of several particles coated with the silane coupling reagent was observed in certain parts of the primary particles. A chemical reaction takes place between the modification reagent, MEMO silane, and active hydroxyl groups on the surface of the nano-SiO2 particles. A larger quantity of MEMO silane reacted using the con­ventional method instead of the supercritical method. On the other hand, the reacted silane molecules were better arranged around the particle surface in the supercritical method because of the formation of covalent or self-assembled structures. Polycondensed structures were preferentially obtained in the conventional method. This was achieved by using supercritical CO2, which has a high solvating power such as organic solvents and physical properties (low viscosity, low surface tension and high diffusion coefficient) similar to gases on the other side. These properties enable the sufficient and uniform wettability of nano-SiO2 particle surfaces. These results are important for obtaining nanofillers with improved dispersion and polymer wettability. Such nanofillers can be used to obtain composite materials with considerably improved mechanical characteristics.
