AB  - Poly(vinylidenefluoride)–ZnO (PVDF–ZnO) nanocomposites with mechanically activated ZnO nanoparticle fillers were investigated using thermal and mechanical analysis and AFM and PFM. Differential scanning calorimetry (DSC) investigated the effect of ZnO nanoparticles on the crystallinity of the polymer, under controlled heating and cooling. Atomic force (AFM) microscopy was used to record the surfaces of the samples. Nanocomposite surface roughness shows the presence of the different phases inside of the matrix, where rough samples contain a higher proportion of the β phase. PFM was performed to investigate the piezoresponse of the composites. Nanoidentation showed that the mechanical activation of the filler (ZnO) increases the Young modulus with the activation time. Molecular simulations in periodic systems (PVDF–ZnO spherical nanocluster and nanocylinder composite) were used to investigate the influence of particle size and shape on the Young modulus of different phases of PVDF.

AB  - Cerium-based conversion coatings have emerged as promising green alternatives to the harmful chromium-based ones, but the mechanism of corrosive protection still remains a subject of academic and industrial research. This study focuses at small scale phenomena of corrosion inhibition imparted by ceria (CeO2) to AA7075. Ceria nanoparticles were deposited from diluted and concentrated CeO2 sols by immersion. A multi-analytical approach, combining Atomic Force microscopy (AFM), Scanning Kelvin Probe Force Microscopy, Glow Discharge Optical Emission Spectroscopy, open circuit potential and electrochemical impedance spectroscopy was employed. Deposition of ceria films led to deactivation of cathodic sites, i.e. decreased Volta potential difference, resulting in increased corrosion inhibition. In situ AFM real-time monitoring revealed that during exposure to NaCl electrolyte, the changes in size of deposited ceria aggregates occurred: nanoparticles disintegrated/desorbed and re-deposited at the coating surface. The process was found to be dynamic in nature. Small particles size and inherent reactivity are believed to accelerate this phenomenon. Due to the greater CeO2 reservoir, this phenomenon was more pronounced with a thicker film, imparting longer term protection.

AB  - Yttrium manganite (YMnO3) is widely investigated multiferroic material with potential use in many technological applications. In this paper, we report on the preparation and characterization of multiferroic hexagonal YMnO3 ceramics obtained by chemical synthesis route. Precursor powders were prepared by the polymerizable complex method from citrate precursors. After calcination at 900 degrees C the powders contained mixture of Y-Mn-O phases which were further sintered at different temperatures. XRD analysis revealed that sintering at 1400 degrees C resulted in the formation of pure hexagonal YMnO3. Density of the obtained ceramics was 96 %TD. The ceramic samples proved to have multiferroic properties - they are antiferromagnetic below 42 K with linear dependence of magnetization as a function of applied magnetic field. The ferroelectric measurements performed at room temperature showed remanent polarization of 0.21 mu C/cm(2) and the coercive field of 6.0 kV/cm for the YMnO3 sample sintered at 1400 degrees C. The magnetization curves measured at 2 and 5 K for the powder samples calcined at 900 degrees C and ceramic samples sintered at 1300 degrees C exhibited a hysteresis loop due to a small concentration of Mn3O4 in the samples.

AB  - In this work, nine products were prepared by modifying the experimental conditions (6, 12 and 18 hat 110, 135 and 160 degrees C) of hydrothermal treatment of starting nanoanatase in significantly less concentrated alkaline medium than usual in order to obtain a pure titanate phase. The nanocrystalline samples were characterized by XRPD, FESEM, HRTEM/SAED, EDS, TG, FT-IR, UV-Vis and BET analyses. The results revealed that the structure, texture, morphology and band gap energy of samples strongly depend on conditions of hydrothermal treatment. The intensification of hydrothermal treatment significantly increases the solubility of TiO2 promoting the changes in morphology from nearly spherical titania nanoparticles to elongated titanate nanosheets. The single titanate phase was obtained after energetically the most intensive treatment, i.e. 18 hat 160 degrees C. The step-by-step optimization was thus necessary to finally distinguish the titanates from titania in terms of structural and spectral properties and to finally allow the clarification of long-standing confusion between titania and titanates. The obtained single titanate phase was furtherly used to fabricate a humidity sensor, which showed remarkably rapid response and quick recovery time.

AB  - In order to get a better insight into the relationship between molecular structure and photovoltaic performance, six monoazo dye molecules containing benzoic and cinnamic acid moieties were synthesized and their photovoltaic properties were studied. Three of them have not been previously used in solar cells. Spectroscopic measurements of the investigated compounds coupled with theoretical calculations were performed. Short-circuit current density, open-circuit voltage, and fill-factor were determined. It was found that a larger amount of short-circuit current density will be generated if the HOMO-LUMO energy gap is lower, determined by the stability of the molecule and the electronic effect of the donor moiety. Among both series of synthesized dye molecules, the highest obtained values of short-circuit current density were achieved with (2-hydroxynaphthalene-1-ylazo)benzoic acid and (2-hydroxynaphthalene-1-ylazo)cinnamic acid, and thus they were regarded as promising candidates for application in dye-sensitized solar cells.

AB  - BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. Optimization of sintering conditions indicated that temperature of 800 degrees C and time of 2 h after pressing at 9 t/cm(2) provided ceramics samples with"the highest density (up to 96% of theoretical density) and the lowest content of secondary phases. Ferroelectric and magnetic characterization was performed on two selected ceramics samples with the highest densities. Ceramics obtained from the powder synthesized by the hydrothermal method showed greater lattice distortion along [1 1 1] axis and smaller grains, which resulted in larger values of electric polarization at room temperature. It also exhibited less Fe(3d)-O(2p) orbital overlapping due to a larger Fe-O-Fe bond angle, causing lower antiferromagnetic ordering and weak ferromagnetic behavior at low temperatures.

AB  - Four novel polymeric iron(III) complexes with 2,2'-bipyridine (bipy) and different aromatic polycarboxylato ligands as anions of phthalic (pht), isophthalic (ipht), terephthalic (tpht) and pyromellitic (pyr) acid were synthesized by ligand exchange reaction. The complexes were characterized by elemental and TG/DSC analysis, FTIR and diffuse reflectance UV-Vis-NIR spectroscopy and magnetic susceptibility measurements. Based on the analytical and spectral data, the formulae of the complexes were {[Fe-4(bipy)(2) (H2O)(2)(OH)(6)(pht)(3)]center dot 2H(2)O}(n) (1), {[Fe-4(bipy)(2)(Hipht)(2)(ipht)(2)(OH)(6)]center dot 4H(2)O}(n) (2), {[Fe-4(bipy)(2)(Htpht)(2)(OH)(6)(tpht)(2)]center dot 4H(2)O}(n) (3) and {[Fe-4(bipy)(H2O)(8)-(OH)(4)(pyr)(2)]center dot H2O}(n) (4). All complexes were red brown and low-spin with a distorted octahedral geometry with FeO6 or FeN2O4 chromophores. The polycarboxylato ligands played a bridging role in all cases, whereas monodentate COO groups were present in 2 and 3, while bridging and chelate COO groups were established in 1 and 4. The thermal behaviours of 1-4 were investigated in detail and the molar dehydration enthalpies were calculated. According to the all those results, the structural formulae of complexes 1-4 were proposed.
AB  - Реакцијом измене лиганада синтетисана су четири нова полимерна комплекса
гвожђа(III) са 2,2′-бипиридином (bipy) и различитим ароматичним поликарбоксилатним лигандима, као што су анјони фталне (pht), изофталне (ipht), терефталне (tpht)
и пиромелитне (pyr) киселине. Комплекси су окарактерисани елементарном и TG/DSC
анализом, FTIR и дифузионо-рефлексионом UV–Vis–NIR спектроскопијом, као и магнетним мерењима. На основу аналитичких и спектралних података, утврђене су следеће
формуле комплекса: {[Fe4(bipy)2(H2O)2(OH)6(pht)3]·2H2O}n (1), {[Fe4(bipy)2(Hipht)2-
(ipht)2(OH)6]·4H2O}n (2), {[Fe4(bipy)2(Htpht)2(OH)6(tpht)2]·4H2O}n (3) и {[Fe4(bipy)-
(H2O)8(OH)4(pyr)2]·H2O}n (4). Сви комплекси су црвеномрке боје и нискоспински са
деформисаном октаедарском геометријом и хромофором типа FeO6 или FeN2O4. Поликарбоксилато лиганди имају мостовну улогу код свих једињења, међутим, док код 2 и 3
постоје монодентатне COO-
-групе, код 1 и 4 нађене су мостовне или хелатне COO–
групе. Детаљно је испитано термичко понашање комплекса 1–4 и израчунате су моларне
енталпије дехидратације. На основу свих добијених резултата, предложене су структурне формуле комплекса 1–4.
