AB  - Galvanization process requires the use a large amount of water and produces wastewaters that are usually purified by conventional cost-effective procedure. This kind of treatment generates waste sludge which becomes a hazardous if is not properly stabilized. Hence, the aim of this paper is to investigate the characteristics of galvanic sludge through the inspection of its physicochemical parameters and consider stabilization of waste materials, including waste glass and aluminum slag by their conversion into an eco-designed material referred to as glass ceramics. The obtained products have been studied by X-ray diffraction (XRD). XRD analyses confirmed occurrence of chemical and phase transformations in treated galvanic sludge and binding of toxic metals (Al3+, Cr3+, Cu2+, Cd2+, Ni2+, Pb2+, Zn2+) into crystalline phases and very sTab. structure.
AB  - Процес галванизације захтева велику количину технолошке воде што има за последицу стварање отпадних вода, које се из економских разлога пречишћавају конвенционалним системима. Овим третманом настаје отпадни муљ који, уколико се адекватно не стабилизује, представља опасан отпад. У том смислу, у раду је извршена карактеризација галванског муља анализом физичкохемијских параметара компонената, а затим стабилизација ових отпадних материја, укључујући отпадно стакло и алуминијумску шљаку, превођењем у еко-синтеровани материјал стаклокерамика. Добијени производ анализиран је рендгенском дифракционом анализом (XRD). На основу XRD спектра потврђене су хемијско-фазне трансформације третираног галванског муља и везивање токсичних метала (Al3+, Cr3+, Cu2+, Cd2+, Ni2+, Pb2+, Zn2+) у веома стабилну кристалну структуру.

AB  - Experimental results on processing, structural and mechanical characterization of a multilayer composite based on commercially pure aluminum foils were presented. A multilayer composite was produced by hot-rolling of anodized and non-anodized aluminum foils alternately sandwiched. In addition, the same process was applied for bonding of non-anodized foils. In both cases, obtained multilayer composites were compact and sound. In order to study composites microstructural evolution and mechanical properties, optical and scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD) analysis, hardness, tensile and three-point flexural tests were performed. Microstructural characterization confirmed that the rod-like particles distributed in parallel rows in the composite aluminum matrix with anodized foils correspond to Al2O3. Maximum and minimum peaks of oxygen and aluminum, respectively, suggest that after the final hot-rolling of composite with non-anodized foils, a small amount of coarser particles were formed at boundaries between foils. Hardness, strength, modulus of elasticity and flexural strength of both multilayer composites were much higher than those of pure aluminum, whereas ductility was significantly less. The composite with anodized foils exhibited the highest strength and modulus of elasticity, but lower ductility compared to composite processed from non-anodized foils. Fracture failure corresponded to the change of ductility.

AB  - Investigations of the high-pressure sintered nanocrystalline mullite powder are presented. The synthesized mullite powder with crystallite size of 51 nm was densified by using high-pressure anvil-type with hollows apparatus at 4 GPa over the temperature range of 1100-1500 degrees C in 100 degrees C steps. The phase composition and structural parameters of the densified samples were studied as a function of densification temperature. The XRD analysis revealed the appearance of new phases, such as kyanite and corundum, whose development affected the densities of the sintered samples. High relative densities of the sintered samples were obtained because of the application of high pressure. The needle-like microstructure was developed owing to the anisotropic grain growth of mullite. The elongated mullite grains reached the length of approximately 5 mu m at 1400 degrees C, whereas the grains treated at 1500 degrees C became thicker preserving the same needle length. The Vickers microhardness of the developed microstructures increased with the increase of temperature up to 1400 degrees C, while at 1500 degrees C it was slightly reduced due to the grain coarsening.

AB  - Amorphous powders of iron doped 3:2 mullite (3Al(2)O(3)center dot 2SiO(2)) were prepared by sol-gel combustion process using ethanol-water solutions of Al(III) nitrate, Fe(III) nitrate, TEOS and urea. Compositions up to 15 wt% of Fe2O3 were investigated. After combustion and heat treatment at 800 degrees C for 4 h, XRD analysis confirmed that the powders were amorphous. This is in agreement with the thermodynamic predictions that direct formation of mullite has not occurred during the aluminum nitrate - urea combustion reaction. XRD patterns of uniaxially pressed and sintered pellets at 1550 degrees C for 4 h revealed the crystal structure of orthorhombic mullite. The lattice parameters and unit cell volume increases as the mullite solid solutions were enriched by iron. The TGA/DSC analysis showed the reducing of crystallization temperature of iron doped mullites with increasing of iron content in reaction mixtures. The mullitization reaction is two-step process including formation of transient spinel phase below 1000 degrees C and mullite crystallization at temperatures about 1200 degrees C. The SEM micrographs of the sintered samples reveal elongated mullite grains with grain length up to 40 mu m. Increasing of the iron content in the reaction mixture enhances the grain size and the grains become elongated and better packed increasing the density of sintered samples. (C) 2014 Elsevier B.V.

AB  - Synthetic biomaterials based on fluorine substituted hydroxyapatite are potentially attractive for orthopedic and dental implant applications. The new synthesis of fluorine substituted hydroxyapatite samples were done by neutralization, which consists of adding the solution of HF and H3PO4 in suspension of Ca(OH)(2). Characterization studies from XRD, SEM and FTIR spectra showed that crystals are obtained with apatite structure and those particles of all samples are nano size, with an average length of 80 nm and about 15-25 nm in diameter. The central composite design was used in order to determine the optimal conditions for the antimicrobial activity of the synthesized samples. In order to evaluate the influence of operating parameters on the percent of viable cell reduction of Streptococcus mutans, three independent variables were chosen: exposure time, pH of saline and floride concentration in apatite samples. The experimental and predicted antimicrobial activities were in close agreement. Antimicrobial activity of the samples increases with the increase of fluoride concentration and the decreased pH of saline. The maximum antimicrobial activity was achieved at the initial pH of 4.

AB  - Two zirconia samples were prepared by precipitation from aqueous zirconium oxychloride and zirconyl sulfate solutions with potassium hydroxide. The prepared zirconia samples were amorphous. The pH(pzc) values of the zirconia samples, determined in NaCl and NaNO3 solutions, were 6.6 +/- 0.1 and 6.9 +/- 0.1, respectively. After prolonged hydration of zirconia in doubly distilled water, the pH(pzc) decreased to 4.7 +/- 0.3. Crystallization into tetragonal (metastable) + monoclinic zirconia appeared at 691 K. Above 873 K, the tetragonal metastable phase changes to a monoclinic phase. It was shown that crystallite sizes of zirconia treated at 673-1273 K increased from 9.5 to 40.5 nm, respectively. The increase in temperature from 385 to 1070 K increased the pH(pzc) of zirconia samples from 6.6 to 9.0, respectively.

Above 873 K, the tetragonal metastable phase changes to a monoclinic phase. It was shown that crystallite sizes of zirconia treated at 673-1273 K increased from 9.5 to 40.5 nm, respectively. The increase in temperature from 385 to 1070 K increased the pH(pzc) of zirconia samples from 6.6 to 9.0, respectively.",

AB  - Results of the wear resistance of the diamond-coated cutting tool inserts upon machining Al-12% Si alloy and glass fiber/polyester resin composites are presented in this paper. The aim of this paper was to demonstrate the advantages of application of cutting tool inserts with the diamond coating over the conventional tungsten-carbide (WC) tools, and to obtain the cheaper serial production (shorter machining time) and satisfactory lifetime of the diamond cutting tool inserts. Surface roughness of the machined samples was measured for both as-received and diamond coated inserts. The diamond microstructure of undamaged part of inserts as well as the appearance of microstructure of diamond coated inserts after machining has been investigated. Results of the behavior of two regimes of preparation of diamond-coated inserts were compared and analyzed. Generally, the wear resistance of the diamond-coated cutting tool is superior over the conventional tool.

AB  - The hydrogenation properties of HfNi and Hf(2)Ni(7) intermetallics were investigated at the constant pressure of 1 bar and in the temperature ranges 373-573 K for HfNi and 323-473 K for Hf(2)Ni(7). The kinetic parameters, rate constants and activation energies of the absorption processes were determined. Maximal hydrogen absorption, i.e., number of hydrogen atoms absorbed per metal atom, HIM, are 1.05 and 0.04 achieved at 373 K for HfNi and Hf(2)Ni(7), respectively. Multiple hydriding/dehydriding was found to influence the improvement of the kinetic parameters. XRD and SEM methods were used to investigate the structural and morphological changes of the samples due to hydrogen absorption. The thermodynamic parameters of hydriding together with the structural properties of the intermetallics and their hydrides, calculated using the full-potential linearized augmented plane waves (FP-LAPW) code based on the density functional theory (DFT), were utilized for the sake of explaining the experimental investigations.

AB  - SiC-TiB2 particulate composites were fabricated by converting TiO2 to TiB2 through the reaction between TiO2, B4C and C. The presence of initially very fine, in-situ created, TiB2 particles increased driving force for sintering and enabled fabrication of a dense composite utilizing pressureless sintering and the liquid phase created between Al2O3 and Y2O3 additives. The effect of volume fraction of the in-situ formed TiB2 on density, microstructure and flexural strength was discussed. It was found that the presence of TiB2 particles suppressed the growth of SiC grains and enhanced fracture strength. The fracture strength of samples containing 12 vol% TiB2 was more than 30% higher than that of the monolithic SIC. The effect of SIC grain size on fracture strength was also analyzed.

AB  - Methods of purification of waste water which are most commonly used in the Republic of Serbia belong to the type of conventional systems for purification such as chemical oxidation and reduction, neutralization, sedimentation, coagulation, and flocculation. Consequently, these methods generate waste sludge which, unless adequately stabilized, represents hazardous matter. The aluminium slag generated by melting or die-casting aluminium and its alloys is also hazardous matter. In this sense, this paper establishes ecological risk of galvanic waste sludge and aluminium slag and then describes the process of stabilization of these waste materials by means of transformation into a glass-ceramic structure through sintering. The obtained product was analyzed with Fourier Transform Infrared Spectroscopy (FT-IR) and X-ray diffraction (XRD). The object of the paper is the eco-technological process of producing glass-ceramics from galvanic sludge and aluminium slag. The aim of the paper is to incorporate toxic metals from galvanic sludge and aluminium slag into the glass-ceramic product, in the form of solid solutions.

AB  - Multiply doped ceria nanopowders were synthesized by applying MGNP (modified glycine/nitrate procedure). The overall concentration of dopants was kept constant (x = 0.2) whereby Gd ion as the main dopant was gradually substituted by Sm and by Sm + Y. The compositions of solid solutions were calculated by applying defect model introducing anion vacancy radius. Characterization of powders involved BET, TEM, XRD and chemical analyses. Densification was performed at 1500 degrees C, in an oxygen atmosphere for 1 h. The results showed that with increasing number of dopants, specific surface area of powders increased, followed by decrease of crystallite and grain sizes. Densification degree was also found to rise with increasing number of dopants. According to impedance measurements it was found that ionic conductivity was the highest 1.14 x 10(-3) S cm(-1) at 450 degrees C in sample doped with Gd, Sm and Y simultaneously.

abstract = "Multiply doped ceria nanopowders were synthesized by applying MGNP (modified glycine/nitrate procedure). The overall concentration of dopants was kept constant (x = 0.2) whereby Gd ion as the main dopant was gradually substituted by Sm and by Sm + Y. The compositions of solid solutions were calculated by applying defect model introducing anion vacancy radius. Characterization of powders involved BET, TEM, XRD and chemical analyses. Densification was performed at 1500 degrees C, in an oxygen atmosphere for 1 h. The results showed that with increasing number of dopants, specific surface area of powders increased, followed by decrease of crystallite and grain sizes. Densification degree was also found to rise with increasing number of dopants. According to impedance measurements it was found that ionic conductivity was the highest 1.14 x 10(-3) S cm(-1) at 450 degrees C in sample doped with Gd, Sm and Y simultaneously.

AB  - Synthesis of La-9.33(SiO4)(6)O-2 was performed by a new method that represents the combination of sol-gel and combustion procedures using glycine as the fuel. Syntheses were performed from ethanol-water solutions of oxides precursors, lanthanum nitrate and tetraethyl orthosilicate. The optimum synthesis parameters have been established by varying molar ratio of tetraethyl orthosilicate to water as well as glycine to NO3- ions. The phase identification and the structural characterization were performed by X-ray powder diffraction. The pure nanocrystalline La-9.33(SiO4)(6)O-2 with the crystallite sizes of 32 nm was directly synthesized during combustion process of homogeneous gel that was generated in solution with the following molar ratios: glycine: NO3- = 0.56 and tetraethyl orthosilicate: water = 1:20. Well-crystallized La-9.33(SiO4)(6)O-2 structure was obtained after heating at 1200 degrees C. The lattice parameters a = 9.7156(9) and c = 7.1810(8) angstrom confirmed the composition La-9.33(SiO4)(6)O-2.

AB  - Flower-like agglomerates with sizes of 200-400 nm of pure and Fe3+-doped TiO2 with rutile crystalline structure were synthesized by the coprecipitation method. The morphology of the agglomerates was determined by electron microscopy (TEM and HRTEM). TiO2 agglomerates consist of nanorods with clearly visible crystalline faces, parallel to the axis of elongation whose direction was along the [101] direction of pure TiO2 and the [111] direction of doped TiO2. Furthermore, nanorods consist of chains of spherical particles, most likely interconnected through the so-called oriented attachment or grain-rotation-induced grain coalescence (GRIGC) process. UV/Vis reflection measurements revealed that the absorption of pure TiO2 was significantly shifted from UV toward the visible spectral region upon the incorporation of Fe3+ into the TiO2 host.

AB  - The reduction of commercial and mechanochemically processed CeO2 powders was studied. Nanostructured CeO2, with the crystallite size of 21 nm and the lattice distortion of 0.37%, was obtained during 60 min of milling in a high-energetic vibratory mill. X-ray diffraction, scanning electron microscopy and Brunauer-Emmett-Teller method were applied to characterize the milled powders. During the thermal treatment at 1200 and 1400 degrees C in an argon atmosphere the nonstoichiometric CeO2-x oxides with the defect fluorite structure were formed. Compositions of CeO2-x oxides were determined according to its lattice parameter. The results showed that the release of oxygen, as well as the rate of reduction, was more effective in nanocrystalline then in the microcrystalline CeO2, producing at 1200 degrees C Ce-1.80 and CeO1.85 oxides, while at 1400 degrees C were obtained similarly, CeO1.77 and CeO1.78, compositions.

AB  - The pure Ce4.67(SiO4)3O with the apatite-type of structure was obtained for the first time from cerium nitrate, glycine and tetraethyl orthosilicate (TEOS) through the self-combustion of the gel. The solution of the reactants with the molar ratio of TEOS to water 1: 42 and glycine to NO3 ¯ 1: 3 was transformed into gel. During combustion of the gel the ash containing nanostructured CeO2 and noncrystalline SiO2 was formed. The phase identification and the measurement of the crystallite size was done by XRD diffraction. Ce4.67(SiO4)3O was synthesized from the ash subsequently fired in argon at 1200 °C.

While constant Ar beam energy of 2 keV was used, the N-2 partial pressure and the substrate current, adjusted by different accelerator grid potentials (V-acc) were varied. A negative substrate bias voltage (100 V) was additionally applied. The TiN film structure was investigated by XRD and STM methods. All deposited films exhibited (220) preferred orientation, and the change in normalized peak intensity (I-220/d), lattice spacing (d(220)) and full-with at half-maximum (FWHM) were investigated. As a result of higher energy bombardment with 100 V negative substrate bias, compared to the substrate current change with V-acc, nearly constant (220) peak broadening with the increase of N-2 partial pressure was obtained. The measured grain diameter (STM and XRD) confirms that the grain size is less than 12 nm, and the (220) preferred orientation was disturbed but not destructed.

AB  - Four ternary compositions in the Ce2O3 rich part of the Ce2O3-SiO2-ZrO2 System were investigated. The corresponding mixtures of CeO2, SiO2 and ZrO2 were fired at 1400 degrees C in an Ar + 7% H-2 atmosphere until the phase equilibria were attained. The samples were characterized by XRD, SEM and EDS analysis. The thermal effects and the mass changes of the fired compositions were monitored by DTA/TG analyses. The oxyapatite phase, Ce-4.67(SiO4)(3)O, and the fee phases identified as the solid solutions (CeZr)O2-y, (CezZr1-z)O2-x, and Ce2Zr2O7+2 delta were observed in this part of the Ce2O3-SiO2-ZrO2 system. The DTA/TGA analyses indicated the presence of the Ce+4 ions in the fired compositions, while the lowest melting temperature was noticed at 1627 degrees C. (c) 2006 Elsevier Ltd. All rights reserved.

AB  - Nanometric powders of solid solutions of cerium oxide were obtained by a modified glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more dopants in the lattice were synthesized. Rare earth cations (Re = Yb, Gd and Sin) were added to ceria in total concentration of x = 0.2 that was kept constant. The criterion in doping was to keep the value of lattice parameter of ceria unchanged, The lattice parameters were calculated by using the model that takes into account the existence of oxygen vacancies in the structure.

AB  - The influence of the heat treatment on the crystal structure change of five (two laboratory prepared and three commercial) silica powders were investigated. Silicas were heat treated in the temperature range from 150 to 1300 degrees C in air. Also, the influence of the washing procedure with 0.01 mol/L HCl in order to desorb cations present as impurities in silica samples, was studied. The change of the amorphous into the crystal structure (alpha-cristobalite) takes place in the range 1050-1300 degrees C, depending on the chemical purity of silica samples. Points of zero charge, pH(pzc), of the same silica samples, ranging from 3.8 to 7.1, were also determined by batch equilibration method. It is shown that the desorption of cations from silica samples, i.e., increase in their purity, leads to a shift in pH(pzc) toward lower values. (c) 2006 Elsevier Inc. All rights reserved.

AB  - An investigation has been conducted on two austempered ductile irons alloyed with Cu and Cu+Ni, austenitized at 900 degrees C and austempered at 350 degrees C. The microstructure and fracture mode developed through these treatments have been identified by means of light and scanning electron microscopy and X-ray diffraction analysis. Impact energy measurements were performed on un-notched Charpy specimens. The maximum value of retained austenite volume fraction observed in the material alloyed with Cu+Ni was higher than in that alloyed with Cu austenitized and austempered under the same conditions. This led to the material alloyed with Cu+Ni having higher impact energy and substantial plastic deformation. (c) 2006 Elsevier Inc. All rights reserved.

AB  - Thin films of nichrome were deposited by d.c. sputtering of a target (80%Ni - 20%Cr w.t.) by Ar+ ions at a working pressure of 10(-1) Pa and at room temperature. The phase composition and grain size were studied by X-ray Diffraction (XRD), while the surface chemical composition was determined by Low Energy Ion Scattering (LEIS). Analysis of phase composition showed that the NiCr thin films were a solid solution of chromium in a nickel matrix with increased nickel lattice parameters. LEIS analysis showed the presence of Ni, Cr and O in the first atomic layer. There is a strong suspicion that surface passivation occurred by forming Cr2O3 oxide at the surface.
