AB  - Taking advantage of the flexibility of the apatite structure, nano- and micro-particles of hydroxyapatite (HAp) were doped with different combinations of rare earth ions (RE3+ = Gd, Eu, Yb, Tm) to achieve a synergy among their magnetic and optical properties and to enable their application in preventive medicine, particularly diagnostics based on multimodal imaging. All powders were synthesized through hydrothermal processing at T ≤ 200 °C. An X-ray powder diffraction analysis showed that all powders crystallized in P63/m space group of the hexagonal crystal structure. The refined unit-cell parameters reflected a decrease in the unit cell volume as a result of the partial substitution of Ca2+ with smaller RE3+ ions at both cation positions. The FTIR analysis additionally suggested that a synergy may exist solely in the triply doped system, where the lattice symmetry and vibration modes become more coherent than in the singly or doubly doped systems. HAp:RE3+ optical characterization revealed a change in the energy band gap and the appearance of a weak blue luminescence (λex = 370 nm) due to an increased concentration of defects. The “up”- and the “down”-conversion spectra of HAp:Gd/Yb/Tm and HAp:Gd/Eu powders showed characteristic transitions of Tm3+ and Eu3+, respectively. Furthermore, in contrast to diamagnetic HAp, all HAp:RE3+ powders exhibited paramagnetic behavior. Cell viability tests of HAp:Gd/Yb/Tm and HAp:Gd/Eu powders in human dental pulp stem cell cultures indicated their good biocompatibility. © 2019, The Author(s).

AB  - We report on the possibility to build hierarchically organized three-dimensional (3D) titania spherical particles having high surface-to-volume-ratio, by aerosol processing of nanotubular building blocks. Morphology and crystal structure of titania based spherical assemblies, obtained in the temperature range from 150 to 650 degrees C, were characterized by means of scanning and transmission electron microscopy, x-ray powder diffraction and Raman spectroscopy. Initial shape of 1D building units, nanotubes, was well preserved in the spherical assemblies processed at 150 and 450 degrees C. Processing at 650 degrees C resulted in a collapse of the nanotubular building blocks and formation of the assemblies of irregularly shaped TiO2 nanoparticles. Structural analysis revealed several phase transitions in titania spherical assemblies in course with the temperature increase indicating possibility of in-situ phase composition adjustment during aerosol processing.

AB  - Spinel materials based on Mn and Ni has been intensively studied over the past years due to their excellent semiconductor properties. Nickel manganite as NTC thermistor is widely used today in different industrial sectors. Here we report the complex polymerization method (CPM) for producing nickel manganite fine particles with a homogeneous distribution of constituent cations in the crystal lattice that ensures formation of dense monophased ceramic with the novel magnetic properties after been sintered in oxygen and air atmosphere. Phase composition of the synthesized materials was examined by XRPD, while the morphology of the powder and microstructure of ceramic were investigated using FESEM and SEM analyses, respectively. The magnetic properties of the samples have been studied by measuring the temperature and field dependence of magnetization. Magnetic measurements of M(T) reveal rather complex magnetic properties and multiple magnetic phase transitions. In the case of air atmosphere we found three magnetic phase transitions with transition temperatures at TM1=35 K, TM2=101 K and TM3=120 K. TM1 maximum is strongly dependent on the strength of the applied magnetic field (TM1 decreases with increasing applied field) whereas the TM3 is field independent The values of the coercivity, remanent magnetization and saturation magnetization at 100 K are: HC = 184 Oe, Mr = 1.92 emu/g and MS = 7.88 emu/g, respectively. The measured values at 5 K are HC = 1035 Oe, Mr = 7.70 emu/g and MS = 14.47 emu/g. Moreover, hysteresis properties measured after cooling of the sample in magnetic field show exchange bias effect with an exchange bias field |HEB=196 Oe. For the sample synthetized in oxygen atmosphere, the magnetization dependence of temperature M(T) and AC susceptibility data obtained from SQUID measurements clearly demonstrates that quadruple magnetic phase transitions can be readily detected at TM1~115 K, TM2~105 K, TM3~38 K and TM4~7 K. These findings suggest the novel magnetic transition for nickel manganite at low temperature TM4. The temperatures of observed maximums in χ’(T) and χ’’(T) parts of susceptibility are frequency independent, whereas the height of the peaks decreases with increasing frequency. The fact that TM4 does not shift with the increase of the frequency led us to the conclusion that there are no spin-glass/surface effect and/or blocking temperature/finite size effect connected to the NiMn2O4 ceramic. Therefore, the low-temperature peak TM4 in AC susceptibility is associated with ferromagnetic-like and antiferromagnetic-like magnetic transition in the interfacial FM/AFM internal structure. The exchange bias effect was found in a field cooled hysteresis loops at 5 K. The field cooling of the sample was under a magnetic field of 100 Oe and 10 kOe whereas the determined exchange bias fields were |HEB|=129 Oe and 182 Oe, respectively. The analysis of the results and comparison with literature data allowed us to conjecture that the mixed oxidation states of Mn ions and ferromagnetic and antiferromagnetic sublattice orders tailor these interesting magnetic properties.

AB  - Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders the authors performed N-2 physisorption, SEM and TEM. Crystallite size and lattice microstrain were analyzed by X-ray diffraction method. XRD patterns indicate that peak intensities are getting lower and expend with activation time. The reduction in crystallite size and increasing of lattice microstrain with prolonged milling time were determined applying the Rietvelds method. The difference between non-activated and the activated powder has been also observed by X-ray photoelectron spectroscopy (XPS). XPS is used for investigating the chemical bonding of ZnO powder by analyzing the energy of photoelectrons. The lattice vibration spectra were obtained using Raman spectroscopy. In Raman spectra some changes along with atypical resonant scattering were noticed, which were caused by mechanical activation. (C) 2015 Published by Elsevier B.V.

AB  - Hierarchically assembled TiO2 nanoparticles into larger spherical ones were obtained using aerosol-assisted processing method. Unagglomerated particles with the mean size of 440 nm were obtained from colloidal solution of TiO2 nanoparticles (similar to 4.5 nm) using ultrasonic spray pyrolysis at 550 degrees C. Their morphological complexity and structural polymorphism were investigated by using X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM) coupled with selected area electron diffraction (SAED) analysis. Pronounced evolution of nanocrystalline TiO2(B) phase assembled together with the anatase building units (sized similar to 15 nm) in uniform submicrometric particles implicate their feasibility to be used in dye-sensitised solar cells and lithium ion batteries.

AB  - Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized material was examined by x-ray powder diffraction (XRPD). Field-emission scanning electron microscopy (FE-SEM) was used to analyze the obtained powder morphology. Scanning electron microscopy (SEM) was used to analyze the microstructure of sintered ceramics. The activation energy of conduction E-a and the coefficient of temperature sensitivity B-25/100 were calculated from direct current (DC) resistivity measurements. The magnetization dependence of temperature M(T) and alternating current (AC) susceptibility data obtained from SQUID measurements clearly demonstrate that quadruple magnetic phase transitions can be readily detected at T-M1 similar to 115 K, T-M2 similar to 105 K, T-M3 similar to 38 K and T-M4 similar to 7 K. These findings suggest a novel magnetic transition for nickel manganite at low temperature T-M4. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Perovskite-related materials with the general formula AC3B4O12 have great technological significance due to their specific physical properties. The crystal structure of AC3B4O12 compounds is cubic with Im3 symmetry. Different cations can occupy A and B sites, while the C site is commonly occupied by Cu2+ or Mn3+ ions. It has been found that the nature of B cation changes the physical properties of the material. In our previous studies we dealt with CaCu3Ti4O12 (CCTO) and CaCu3Ru4O12 (CCRO) compounds. CCTO has the gigantic permittivity of 104105 in the kilohertz region and good stability over the temperature range from -170 to 330 °C. While Ti-compound is semiconductor, the Ru one is conductive oxide and could be used as interfaces between CCTO and metallic electrodes. Thus, CCTO and CCRO have potential application for preparation of layer capacitors with CCRO as the electrode and CCTO as the dielectric material. Since the oxygen vacancies and/or intrinsic defects in perovskites have a crucial role in the physical properties it is important to determine crystal structure of ceramic materials. In this work, a detailed structural investigation of CCTO and CCRO perovskites was performed. The powders were prepared by precipitation and successive calcination at 1100 °C with 3 h dwell time to obtained single phased materials. The phase composition and crystal structure of synthesized powders were studied by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), selected-area electron diffraction (SAED) and Raman spectroscopy analyses. Rietveld refinement of XRD data was used to calculate the powders stoichiometry. Furthermore, since the XRD method is not adequate for determination of oxygen atoms due to their small scattering factors, to confirm the (oxygen-) stoichiometry of the ceramic powders, thermogravimetric (TG) measurements were employed. Two sets of experiments were performed; powders were heated in a flowing: (1) air atmosphere, and (2) reducing atmosphere (mixture of 5% H2 with Ar; 20 ml/min), to 1100 °C with a heating rate 10 °C/min with 3 h dwell time. TG measurements were performed on system coupled to a quadrupole mass spectrometer used for determination of volatile compounds. The weight losses measured by TG, in two different atmospheres, were compared; minor deviations in stoichiometries of CaCu3B4O12 compounds determined by Rietveld refinement were corrected.

AB  - Hierarchically organized functional nanomaterials are of interest for potential use in electrochemical, catalytic and gas-sensing applications due to their unique structural organization defined on different length scales. Here we present the application of the aerosol processing route in generation of hierarchically organized nanostructured TiO2 particles. Particles are obtained by the thermal decomposition of aerosol generated by atomization of colloidal TiO2 solution with a low-intensity ultrasound generator operating at the high frequency of 1.7 MHz. By a proper choice of the precursors type and concentration, as well as processing parameters (temperature of aerosol decomposition and the residence time of droplet/particle), fine control over both the submicron- and nanometer-length scales of spherically structured TiO2 was achieved. The median diameter and the crystallite size of titania particles were found to be tunable from 350 to 450 nm and from 2.5 to 50 nm, respectively. Moreover, it was shown that the structural complexity of the particles synthesized at the lower processing temperatures might be further extended by their surface sensitization with several bidentate ligands. The results obtained demonstrate advantages of ultrasonic spray pyrolysis route in synthesis of hierarchically organized functional nanomaterials.

AB  - The effect of Sn for Ti substitution on the crystal structure of a perovskite, barium titanate stannate (BTS), BaTi1-xSnxO3 for x = 0, 0.025, 0.05, 0.07, 0.10, 0.12, 0.15 and 0.20, was investigated. The powders were prepared by the conventional solid-state reaction technique. The structural investigations of the BTS powders were done at room temperature by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), selected-area electron diffraction (SAED) and Raman spectroscopy analyses. Rietveld refinement of XRD data indicates that gradual replacement of titanium by tin in BaTiO3 provokes a phase transition from tetragonal for 0 LT = x LT = 0.07 to cubic for x = 0.12, 0.15 and 0.20. The coexistence of tetragonal (P4mm) and cubic (Pm (3) over barm) crystal phases was established in powder with nominal composition BaTi0.9Sn0.1O3. The crystal phases determined by Rietveld refinement were confirmed by HRTEM and SAED analyses. The crystal structures of the BTS powders at short-range scale were studied by Raman spectroscopy, which shows tetragonal (P4mm) and a small fraction of orthorhombic (Pmm2) crystal phases for all the examined BTS powders, implying a lower local ordering when compared to the average symmetry.

AB  - Sub-micronic, spherical Y2O3:Yb/Er particles comprising clustered nano-units (70 nm) were prepared via ultrasonic spray pyrolysis from pure nitrate precursor solutions with different Yb/Er dopant ratios. The particles were additionally thermally treated at 1100 degrees C for 12, 24 and 48 h. The structural and morphological characteristics of particles were studied by X-ray powder diffraction, Fourier transform infrared spectroscopy, field-emission scanning electron microscopy, energy dispersive X-ray analysis and specific surface area (BET) and were further correlated with their advanced optical properties. For the recorded up-conversion emissions, originating from the following Er3+ transitions: [H-2(9/2) - GT I-4(15/2)] in blue (407-420 nm); [H-2(11/2), S-4(3/2) - GT I-4(15/2)] green: 510-590 nm; and [F-4(9/2) - GT I-4(15/2)] in red (640-720 nm) spectral region, the corresponding lifetimes were acquired in the wide temperature range (10-300 K). The most intense green up-conversion emission with the long decay of 550 ms is recorded for Y1.97Yb0.02Er0.01O3 particles thermally treated at 1100 degrees C for 24 h.

AB  - Spherical, submicronic TiO2 powder particles were prepared in the low temperature process of ultrasonic spray pyrolysis (150 degrees C) by using as a precursor aqueous colloidal solutions consisting of surface modified 45 angstrom TiO2 nanoparticles with dopamine. Detailed structural and morphological characterization of colored submicronic TiO2 spheres was performed by X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), laser particle size analysis and FTIR techniques. Also, optical characterization of both dopamine-modified TiO2 precursor nanoparticles and submicronic TiO2 powder particles was performed using absorption and diffuse reflectance spectroscopy, respectively. A significant decrease of the effective band gap (1.9 eV) in dopamine-modified TiO2 nanoparticles compared to the band gap of bulk material (3.2 eV) was preserved after formation of submicronic TiO2 powder particles in the process of ultrasonic spray pyrolysis under mild experimental conditions. Due to the nanostructured nature, surface-modified assemblage of TiO2 nanoparticles preserved unique ability to absorb light through charge transfer complex by photoexcitation of the ligand-to-TiO2 band, conventionally associated with extremely small TiO2 nanoparticles (d LT 20 nm) whose surface Ti atoms, owing to the large curvature, have penta-coordinate geometry.

AB  - Thermographic phosphors are oxides doped With rare-earth or transition metal ions that will emit visible, Infrared, or UV light upon excitation from an external energy source This materials have received significant attention due to the potential application as optical temperature sensor In this report, we have investigated yttrium oxide co-doped with changeable ytterbium to erbium ratio (Y1.94YbO.05Er001 and Y1 97YbO 02ErO 01) fabricated through hydrothermal synthesis Process conditions (2h, 200 'C) and additional thermal treatment (3h, 1100 'C) allows obtaining nanoparticles of appropriate composition and morphology which further affect on improved photoluminescent characteristics. The fluorescence Intensity ratio (FIR) technique is used to examine potential usage of samples as low temperature sensors. This optical method is based on ratio between two emission lines or areas In photoluminescence spectrum which show temperature dependence.

The diverse levels of structural, morphological and functional complexity were explored simply by means of appropriate selection of different colloidal precursor solutions of either nearly spherical nano-particles[1] (a), surface modified nano-particles with dopamine (b) or nano-tubes (c). The detailed structural and morphological investigations were done by X-ray powder diffraction (XRPD), laser particle size (LPS) analysis, scanning and field emission electron microscopy (SEM/FESEM) and transmission electron microscopy (TEM). Spherical, submicronic, soft and grained TiO2 particles with the mean size from ~350 to ~450nm and with clustered inner structure, composed of primary nanocrystals (<10nm), were obtained. The optical properties and surface structure were analyzed by UV-Vis diffusive reflectance (UV-Vis DRS) and Fourier transform infrared (FTIR) spectroscopy. The obtained results offer a general route for the synthesis of self-assemblies with tunable morphology and optical properties. A significant decrease of the effective band gap values (1.7 to 1.9eV) for the processed TiO2 nanoparticles, compared to the band gap of bulk material (3.2eV), was achieved. Such hierarchical nano-structured powders, are expected to have potential application not only in the field of photovoltaic technologies[3] but also in various aspects of photo catalysis.[4]References:[1] Dugandžić I.M., Jovanović D.J., Mančić L.T., Zheng N., Ahrenkiel S.P., Milošević O.B., Šaponjić Z.V. and Nedeljković J.M., 2012 Surface modification of submicronic TiO2 particles prepared by ultrasonic spray pyrolysis for visible light absorption, J.

AB  - Nanocrystalline up-converting Y₂ O₃Yb³⁺ Er³⁺ phosphor particles were processed in a dispersed system-aerosol, generated ultrasonically at 1.3 MHz from common nitrate precursor solution having fixed ytterbium-to-erbium concentration ratio. The appropriate process parameters: residence time 21 s, carrier gas (air) flow rate 1.6 dm3/min, synthesis temperature 900 °C, led to the formation of un-agglomerated spherical nanostructured secondary particles, having mean particle size of approx 450 nm, composed of primary nanoscaled (20 nm) subunits. In order to reach targeting phase crystallinity, the as-prepared particles were additionally annealed at 1100 °C in air for 12, 24 and 48 h, respectively. Particle structure, morphology and purity were analyzed by X-ray powder diffraction (XRPD), scanning electron microscopy (FESEM/SEM), analytical and high resolution transmission electron microscopy (TEM/HRTEM) in combination with energy dispersive X-ray analysis and Fourier Transform Infrared Spectroscopy (FTIR). All samples crystallized in a cubic bixbyte-structure, space group Ia-3. The crystallite size changed with annealing time from 30 nm in as-prepared sample to 135 nm in sample annealed for 48 h, respectively. Emission spectra were assigned to the following trivalent erbium f–f electronic transitions: ²H₉/₂ → ⁴I₁₅/₂ (blue: 407–420 nm), (²H₁₁/₂̦ ⁴S₃/₂) → ⁴I₁₅/₂ (green: 510–590 nm), and ⁴F₉/₂ → ⁴I₁₅/₂ (red: 640–720 nm). The significant improvement of the emission decay times were observed after thermal treatment and this effect is correlated further with the structural and morphological particles characteristics. For the anneal-ing time of 12 h a quite high emission decay times were achieved (blue: 0.14 ms, green: 0.32 ms and red: 0.39 ms).

AB  - In order to develop new nanosized filler compatible with the thermoplastic polymer Nyion-11, trititanate nanotubes (TTNTs) were synthesized by standard alkaline hydrothermal treatment of a TiO2 anatase powder in 10 M NaOH at 120 DC for 24 h. After the synthesis, the as-obtained nanopowder was washed differently (either with water or HC1), in order to prepare TTNTs with high and low sodium contents. Chemical functionalization of TTNTs was performed with 3-minopropyltriethoxisilane (APTES) coupling agent using two different reaction media (water and an ethanol/water mixture) with the aim to improve the bonding between inorganic hydrophilic fillers and hydrophobic polymer matrix. Fourier transform infrared spectroscopy (FTIR), thermogravimetry analysis (TGA), transmission electron microscopy (TEM), zeta potential and CHN elemental analyses were used to elucidate the grafting mechanism of APTES at TTNTs surface. The obtained results shown that: APTES coupling agent is bounded covalently to the TTNTs surface (Ti-O-Si bond was identified after deconvolution of the IR bands at 800-1000 cm-1); grafted amount of APTES is almost independent of the reaction media; protonation of-NH2 groups shift the isoelectric point from pH 2.4 to pH 6.6; TTNTs kept their original size and shape after silanization.

AB  - Up-converting yttrium oxide powders doped with Yb3+ and co-doped with Ho3+ weresynthesized through hydrothermal processing at 200 °C/3 h. Reverse precipitation of the starting nitrates mixture is performed with the help of ammonium hydrogen carbonate (AHC) solution up to pH 7 or pH 9 prior to hydrothermal treatment. Morphological features of the as-prepared (asp)powders and rare earth oxides obtained after powders additional annealing at 1100 oC (3 and 12 h)are discussed based on X-ray powder diffractometry (XRPD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Structural refinement confirmed generation of the cubic bixbyte-structure (S.G. Ia-3) with non-uniform accomodation of dopants at C2 and S6 cationic sites. SEM revealed that the particles have plate-like or rod-like morphology in dependence of hydrothermal processing (pH). Due to the fact that are composed from nanograins (30-100 nm) they demonstrate prominent green luminescence centered at 550 nm after been excited with the infrared laser source (λ=978 nm).

AB  - The aerosol route, representing a feasible bottom-up technique for nanomaterials processing in disperse system, was applied for the low-temperature (T=150 oC) synthesis of spherical, nonagglomerated, hierarchically organized titania and titanates nanostructures. The diverse levels of structural, morphological and functional complexity were explored by using appropriate colloidal precursors comprising either spherical nanoparticles or nanotubes. In both cases, spherical, grained, submicronic sized particles with the average diameter of ~350 nm for titania and ~ 450 nm for titanates were obtained. The detailed structural and morphological investigations were done according to X-ray powder diffraction (XRPD), scanning and field emission electron microscopy (SEM/FESEM), particle size distribution (PSD) and transmission electron microscopy (TEM) results. Results revealed that particles have clustered inner structure and are composed from primary nanounits in form of nanoparticles or nanotubes. Such hierarchically organized particles are expected to have potential application not only in the field of photovoltaics but also in various branches of photocatalysis.

AB  - Theoretical and experimental investigation of the particle formation during processing of colloidal nanoparticles in aerosol laminar flow reactor is presented. Simple analytical model taking into consideration all important process parameters, such as physico-chemical properties of the colloidal solution, initial droplet size, residence time and temperature, is developed in order to predict the final particle morphology. The formation of spherical, hierarchically organized, ~450 nm sized TiO2 particles has been followed at 150°C starting from colloidal TiO2 nanoparticle (~4.5 nm) solution as precursor. It has been shown that the final particle morphology is formed in the evaporation/drying stage through the self assembly processes of colloidal nanoparticles collision and aggregation. The dimensionless numbers Re, Nu, Pr and Bi, were used in modeling to briefly describe the transport properties in dispersed system and heat and mass transport phenomena. The predicted particle size and morphology is confirmed by using scanning electron microscopy (SEM/FESEM) and laser diffraction particle size analyzer (LPS). Additionally, closer morphological investigation is performed with transmission electron microscopy (TEM) and nanotomography. Correspondingly, theoretical analysis under this study presents a simple procedure to predict the final morphology and mean particle size during aerosol processing.
