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

AB  - Within this doctoral dissertation, the influence of mechanochemical and chemical synthesis parameters on the structure and properties of yttrium manganite (YMnO3, YMO) powders and ceramics was investigated. Mixture of Y2O3 and Mn2O3 was milled in a planetary ball mill for periods of 60 – 720 min. X-ray analysis of the resulting powders showed that single-phased orthorhombic YMnO3 (o-YMO) powders were obtained for milling periods of 240, 360 and 720 min. The size of primary particles in the powders was below 100 nm, while a prolongation of the milling time led to agglomeration. The magnetic properties indicated that the powders were basically antiferromagnetic with partially disordered spins by the presence of Mn4+ ions...

AB  - Nanostructured single layered (pure TiO2 , pure α-Fe2O3 and mixed Fe2O3 /TiO2 with two different oxide ratios, 2 : 3 and 3 : 2) and double layered (TiO2 layer over a Fe2O3 layer) thick films have been fabricated by screen printing technology on a glass substrate. The pastes used for film preparation were obtained by adding an organic vehicle to the oxide powders together with a small percentage of binding glass frit. Samples were dried up to 100 °C and sintered at 650 °C/60 minutes. Structural, morphological and optical studies have been carried out using XRD, SEM analyses and UV/Vis spectroscopy. The prepared pure and mixed Fe2O3 /TiO2 thick films had a homogenous nanostructure without secondary phases. Indirect band gaps were determined from the measured transmission spectra and the obtained values are in the range of literature data. [Projekat Ministarstva nauke Republike Srbije, br. III45007]

AB  - Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), and (ii) metal-nitrate salts and polyethylene glycol (PEG), in the presence of potassium chloride as a capping agent. The as-prepared gel precursors were characterized by TGA/DTA, while the samples obtained after annealing at 450 degrees C were investigated by FTIR, FESEM, XRD and Mossbauer spectroscopy. Regardless of the type of carboxylic acid used, nanocrystallites prepared by (i) method are similar in size (11-16 nm), while the method (ii) gives crystallites similar to 33 nm in size with negligible microstrain. The differences in the lattice parameter, ranging from 8.3369(2) to 8.3574(2) angstrom, result from cation distribution, nonstoichiometry and structural imperfections in the nickel ferrite nanoparticles. The Mossbauer spectra analysis indicates existence of large distortions of tetrahedral and octahedral sites in these spinel compounds. (C) 2013 Elsevier Ltd and Techna Group S.r.l.

AB  - The kinetics of multi-step thermal degradation of Co(II) complex with N-benzyloxycarbonyl glycinato ligand [Co(N-Boc-gly)(2)(H2O)(4)]center dot 2H(2)O, in non-isothermal conditions was studied using isoconversional and non-isoconversional methods. The degradation of complex occurs in three well-separated steps involving the loss of water molecules in first step followed by two degradation steps of dehydrated complex. The dependence of Arrhenius parameters on conversion degree showed that all observed steps of thermal degradation are very complex, involving more than one elementary step, as can be expected for most solid-state heterogeneous reactions with solid reactants and solid and gaseous products. It was shown that step 1, corresponding to the dehydration, involves a series of competitive dehydration steps of differently bound water molecules complicated by diffusion. Second step involves two parallel reactions related to the loss of two identical C6H5CH2O-ligand fragments complicated by the presence of products in gaseous state. Further degradation in step 3 corresponds to complex process with a change in the limiting stage, in this case from the kinetic to the diffusion regime, connected with the presence of gaseous products diffusing through the solid product.

AB  - The intermediate member of the (Bi,Sb)(2)S-3 solid-solution series was prepared by dry synthesis at low temperature (200 degrees C) with a long annealing period in sealed silica tube. The EDS analysis yielded an empirical formula (Bi0.96Sb1.04)S-3, which is very close to the formula (Bi0.94Sb1.06)S-3 obtained by crystal structure analysis. The crystal structure was refined to the R-factors: R-1 = 0.0288 for I  gt  2 sigma(I) and wR(2) = 0.0542 for all data. (Bi0.94Sb1.06)S-3 has orthorhombic symmetry with space group Pnma (No. 62). The asymmetric unit contains two independent mixed cation sites, both coordinated to seven S atoms in a form of mono-capped trigonal prism. They combine into infinite (M4S6)(n) rods parallel to the [010] direction with only weak interactions between rods where the lone electron pairs are directed. Our data and the revaluation of previous data resolve a controversy about the distribution of Sb and Bi over the two structural sites which exists in previously published works. It is shown that the structural constraints favour a slight preference of the larger cation for the marginal M1 site over the whole span of the solid-solution series. The unit cell parameters show a deviation form the Vegard's law connected with different rates of the parallel increase of lengths of the strong bonds and the decreasing influence of the lone electron pair with the replacement of Sb by Bi. The changes in the character of the two independent cation sites introduced by this replacement are similar to those produced during compression of Sb2S3.

AB  - Multi-step thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n) in non-isothermal conditions was studied. The kinetic parameters were determined from the thermal decomposition data using the isoconversion and non-isoconversion techniques. It was shown that the coordination polymer is stable up to 60 C, when the multi-step process of thermal dehydration, followed by steps of degradation, starts. The kinetic triplet for the step of dehydration was established as f(alpha) = 3/2(1 - alpha)(2/3)[1 - (1 - alpha)(1/3)](-1). E-inv = 170.4 +/- 6.4 kJ mol(-1) and Z(inv) =2.6 x 10(23). The established kinetic model, known as "D3 model", was confirmed by application criteria defined by Malek, Perez-Maqueda et al. as well as Master plot method. Dehydration step is followed by two steps of dehydrated coordination polymer degradation. On the base of the dependence of Arrhenius parameters (E-a and Z) on conversion degree (alpha), the mechanisms of degradation were discussed. In this way it was shown that second and third steps of degradation of coordination polymer are complex involving more than one elementary step. The second step corresponds to the loss of two C6H5CH2O- fragments in two parallel steps. The third step of degradation, ascribed to the loss of two -C(=O)NHCH2- fragments, is complicated by changing kinetically to diffusion control. (C) 2011 Elsevier B.V. All rights reserved.
