AB  - Glassy carbon samples containing boron are produced via two different procedures. Boron was introduced into the glassy carbon precursor to avoid the commonly used high temperature doping process and also to obtain the samples of glassy carbon with boron uniformly distributed throughout the bulk of a material. Structural analysis of specimens treated under different temperature-pressure conditions shows that boron enhances the structural ordering of all samples but not to the same extent, clearly indicating that boron in different samples occupies different structural positions.

AB  - Enhanced degradation of organic dye was achieved using two different kinds of waste materials: waste tire granules and spent sealed radioactive sources. Waste tire granules were used as raw material for the production of waste tire char (WTC), which was further utilized as an adsorbent matrix for synergetic adsorption/irradiation degradation of organic dye. The spent radioactive sources were radiographic sealed sources that originate from the industry which generate the high energy radiation. Methylene Blue (MB) was used as an organic model compound. Synthesized WTC has turbostratic structure, irregular shaped particles and developed mesoporous surface. Complete degradation of 0.02 dm3 of 100 mg dm−3 MB solution, having WTC dose of 1.25 g dm−3, was achieved with delivered doze of only 60 Gy. The applied doses were 100 times smaller than those presented in the literature. Degradation pathway was determined: OH radicals that originate from radiolysis of water and from the surface of WTC played the crucial role in the radiocatalytic degradation of MB. Breakage of the aromatic ring of MB appeared by the scission of the double C‒S+˭C bond as a result of the attack of OH species on adsorbed and electronically reorganized MB molecule. © 2020 Elsevier B.V.

AB  - Development of method for the complete conversion of Cr-containing electroplating sludge (ES) into the black inorganic pigment was presented. Difficulties related to the ES complex, variable composition and inhomogeneity, where the dominant presence of Cr was followed by: Fe, P, Zn, Ni, Cu, etc., can be overcome by determination of the precise amount of Fe2O3 necessary to be added in order to firmly embed all the heavy metals into the pigment structure (i.e. the Fe0.7Cr1.3O3/FePO4 nanocomposite), taking care not only about weight/molar ratios, but also about average particle size, apparent densities, and volume fraction of the starting materials. As a source of Fe2O3, commercial (p.a.) Fe2O3 and two different Fe-wastes were used, thus completely fulfilling the principles of the circular economy. The obtained black inorganic pigments have consistent composition, no leaching of toxic metals, color (CIE L-a-b-values) comparable with those of commercial pigments and thus have the potential commercial large scale application. © 2021 Elsevier Ltd.

AB  - Solid-phase extraction (SPE) on activated carbon derived from coconut shell (CSAC) for the preconcentration of four varying polarity pesticides (imidacloprid, acetamiprid, simazine, and linuron) prior to their determination using high performance liquid chromatography with diode array detector (HPLC-DAD) was investigated. The characteristics of the CSAC were analyzed through X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) method. The effects of the solution pH, eluent type, eluent volume, and flow rate were investigated for optimization of the presented procedure. The adsorption was achieved quantitatively on the CSAC column in the pH range of 2.0–7.0, and then the retained pesticides were eluted with dichloromethane. The detection limit was found to be 0.025–0.039 μg L−1, depending on the pesticide. The proposed SPE-CSAC method was used to determine selected pesticides in tap water samples. The recoveries ranged from 58.2 to 105.3%, with low relative standard deviations. The obtained results indicated that the CSAC could be efficiently used as a low cost alternative to commercially available SPE adsorbents for the determination of the varying polarity pesticides in environmental water samples at trace levels. © 2019, Springer Nature Switzerland AG.

AB  - In the present study, an aluminum alloy A356 composite with addition of 5 wt% fly ash was synthesized and subjected to the cavitation erosion resistance test in order to find out if this material can be used in conditions where the cavitation erosion resistance is expected. Obtained results were compared with that of as-cast aluminum A356 alloy, confirming that composite possessed better cavitation erosion resistance than original alloy and that fly ash can be used as an effective reinforcement in metal matrix composites production. Scanning electron microscopy and optical microscopy was used for microstructural analysis. Phase identification of fly ash was carried out using X-ray diffraction analysis. Several methods for monitoring the cavitation erosion resistance of A356 alloy and corresponding composite were applied, such as: mass loss (Delta m), volume loss (Delta V), level of surface degradatiom (P/Po) and pit depth.

AB  - The most promising method for obtaining a large variety of non-oxide products having important technical uses is carbothermal-reduction reaction (CRR). By using this procedure, SiC and ZrC/SiC powders are obtained from diatomaceous earth and zircon powder. In this way the synthesized powders are obtained at a relatively low temperature due to good homogenization. Starting C/ZrSiO4 admixtures having different molar ratios (3:1, 4:1, 5:1 and 7:1) and C/SiO2 having ratios 1:1, 3:1, 4:1, and 7:1 were heated at temperatures between 1300 and 1600 degrees C in a controlled Ar flow atmosphere. The phase evolution was a function of the raw materials molar ratios and sintering temperature. The optimal parameters for the synthesis of SiC and ZrC/SiC powders were obtained. The results obtained by EDS analysis are in good agreement with those obtained by XRD analysis for the synthesized carbide powders. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Interactions between macromolecules in the cell walls of different plant origin were compared, namely spruce wood (Picea omorika (PaniA double dagger) PurkiAe) as an example of softwood, maple wood (Acer platanoides L.) as a hardwood and maize stems (Zea mays L.) as a herbaceous plant from the grass family and widely used agricultural plant. Interactions of macromolecules in isolated cell walls from the three species were compared by using Fourier transform infrared spectroscopy, X-ray diffraction and fluorescence spectroscopy. Linear dichroism of the cell walls was observed by using differential polarization laser scanning microscope (DP-LSM), which provides information of macromolecular order. This method has not previously been used for comparison of the cell walls of various plant origins. It was shown that the maize cell walls have higher amount of hydrogen bonds that lead to more regular packing of cellulose molecules, simpler structure of lignin, and a higher crystallinity of the cell wall in relation to the walls of woody plants. DP-LSM and fluorescence spectroscopy results indicate that maize has simpler and more ordered structure than both woody species. The results of this work provide new data for comparison of the cell wall properties that may be important for selection of appropriate plant for possible applications as a source of biomass. This may be a contribution to the development of efficient deconstruction and separation technologies that enable release of sugar and aromatic compounds from the cell wall macromolecular structure.

AB  - A cordierite/SiC composite was created in situ with reactive sintering at 1250 degrees C and 1300 degrees C. The cordierite precursor was made from commercially available spinel, alumina and quartz and was mixed with the comercial SiC powder to obtain composite materials during the sintering. It was found that cordierite particles bind efficiently with the SiC powder during sintering and that reactive sintering is an effective way to produce ceramics at a relativly low temperature. The goal of this investigation was to check the possibilities of using the silicon carbide-cordierite composite as a material resistant to the erosive wear. The fluid dynamic system of the experimental methodology was used here to produce ultrasonic erosive wear. Two kinds of SiC/cordierite samples were investigated, KS 50 and KS 30, with different mass contents of cordierite (w = 50 % and w = 30 % of cordierite). The mass loss and the level of surface degradation were measured before and during the experiment. The level of surface degradation of the samples was monitored using the Image-Pro Plus program for the image analysis. It was found that after 150 min the mass loss was below 1.3 mg and the surface degradation was below 7 %. The obtained results indicated that both samples exhibited an excellent erosion resistance during the cavitation experiment.

AB  - The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of boiler tubes is indispensable measure for prevention of future malfunctions of power units. The microscopic examination of economizers inner wall microstructure, the analysis of chemical composition of deposit using X-ray diffraction (XRD) and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS) have been performed in a subcritical power plant. Stress corrosion cracking, pitting corrosion, destroyed protective magnetite layer, presence of magnetite and hematite in deposit and corrosive impurities within the cracks have indicated the effect of inadequate quality of feedwater that cannot entirely ensure reliable operation of the boiler. It may be stated that maintenance of present boiler does not provide its reliable operation. The extensive chemical control of water/steam cycle was recommended.

The starting powders were obtained by a carbothermal reduction (CTR) of natural mineral zircon (ZrSiO4), which provided an intimate mixing of in-situ created ZrC and SiC powders. This composite powder and LiYO2 as additive were densified by spark plasma sintering. Microstructural features of the composite were investigated by XRD, SEM/EDS and AFM analysis. The sintered composite material possesses promising mechanical properties and excellent cavitation resistance which was observed with a cavitation erosion test. The values of Vickers microhardness and fracture toughness of the composite material are 20.7 GPa and 5.07 MPam(1/2), respectively. (C) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

Reactive sintering is an effective way to produce ceramics at relatively low temperature. We have created in situ SiC/cordierite composite at 1250 degrees C. Cordierite precursor was made from commercially available spinel, alumina and quartz. The possibilities of using silicon carbide-cordierite material as resistant to the erosive wear was goal of this investigation. The fluid dynamic system of the experimental methodology was used here to produce ultrasonic erosive wear. Mass loss and level of degradation were measured before and during the experiment. Level of degradation of the samples was monitored using Image Pro Plus program for image analysis. Average erosion ring diameter as well as average erosion area were monitored during experiment. Obtained results pointed out that after 150 min sample exhibited excellent erosion resistance compared to metal and ceramic samples. (C) 2013 Elsevier Ltd. All rights reserved.",

Powders with nominal compositions Ca0.95Gd0.05MnO3, Ca0.9Gd0.9MnO3, Ca0.85Gd0.15MnO3 and Ca0.8Gd0.2MnO3 were prepared using a modified glycine nitrate procedure. Obtained powders were calcinated in the temperature interval from 850 degrees C to 950 degrees C for 10 min. All samples where characterized by DTA, XRD and SQUID magnetometry. The possibility of incorporation of Gd ions in the positions A of the perovskite structure was investigated by X-ray methods. Influence of Gd on unit cell volume of the perovskite compounds, occupation numbers and distances between atoms were analyzed by Rietveld refinement. Microstructure size strain analysis was performed, as well. The results revealed that Gd entered positions A in the structure. Magnetic measurements showed that a Gd3+ substituted Ca2+ ions changes antiferromagnetic properties of CaMnO3 by introduction of ferromagnetic interaction due to a double exchange between Mn3+ and Mn4+ ions.

AB  - The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600 degrees C). Carbothermal reduction process is greatly influenced by chemical composition of sepiolites and type of carbon used. Obtained SiC powders consist of fine beta-SiC particles and did not retain the fibrous morphology of sepiolites. Catalytical influence of Fe is attributed to formation of iron-silicide and its potentionaly important role in removal of Mg-species, i.e. reduction of Mg2SiO4 and MgO into Mg-(g).

AB  - The effect of the simultaneous presence of nano- and micro-sized Al2O3 particles on the microstructure and properties of copper matrix was the object of this study. The mixture of inert gas-atomized prealloyed copper powder (with 1 wt.% Al) and 0.6 wt.% commercial Al2O3 powder (serving as micro-sized particles) was used as the starting materials. Strengthening of the copper matrix was performed by treating the powders in the air for up to 20 h in the planetary ball mill. During milling of the prealloyed powder, finely dispersed nano-sized Al2O3 particles were formed in situ by internal oxidation. The approximate size of these particles was between 30 and 60 nm. The highest values of microhardness were reached in compacts processed from 10 h-milled powders. The microhardness of compact obtained from 10 h-milled powder was 3 times higher than the microhardness of compact processed from as-received and non-milled prealloyed powder. At the maximum microhardness the grain size reaches the smallest value as a result of the synergetic effect of nano- and micro-sized Al2O3 particles. Recrystallization, which occurred during prolonged milling, was the main factor influencing the decrease in microhardness. The increase in electrical conductivity of compacts after 15 h of milling is the result of the decrease in microhardness and activated recrystallization processes. (C) 2012 Elsevier Inc.

AB  - This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ratio is thoroughly investigated for a wide range of compositions (C/ZrSiO4 = 1-8) and temperatures (1473-1973 K). The zircon powder was mixed with activated carbon as a reducing agent and heat treated in a controlled flow atmosphere of Ar. Periclase (MgO) was added in order to facilitate the formation of high temperature form of zirconia as well as to examine the possible catalytic effect of MgO on the overall reaction. Phase evaluation and phase content were followed as a function of temperature, C/ZrSiO4 ratio and different quantity of introduced MgO. The obtained powders were characterized by means of ex-situ X-ray diffraction and SEM/EDS investigation. It was found that, depending on C/ZrSiO4 ratio, it is possible to produce either a m-ZrO2, c-ZrO2 or ZrO2/SiC powders by using zircon as precursor. (C) 2010 Elsevier B.V. All rights reserved.

AB  - Ca0.9Gd0.1MnO3 nanopowders with perovskite type crystal structure were synthesized by modified glycine nitrate procedure. Nanopowders were prepared by combining glycine with metal nitrates and/or metal acetates in their appropriate stoichiometric ratios. Modification of the procedure was performed by partial replacement of nitrates by acetates, in order to control the burn-up reaction. Obtained Ca0.9Gd0.1MnO3 powders were calcinated in the temperature interval from 850 degrees C to 950 degrees C for 10 min. Properties such as phase evolution, lattice parameters, chemical composition and magnetic properties were monitored by DTA, X-ray diffraction, SEM/EDS and magnetic measurements. Magnetic measurements performed at the sample with the smallest crystallite size showed that a 10% of Gd3+ substituted Ca2+ ions changes antiferromagnetic properties of CaMnO3 by the introduction of ferromagnetic interaction due to a double exchange between Mn3+ and Mn4+ ions. Presence of competing interactions and their randomness lead to a formation of a spin glass state below Neel temperature T-N = 110 K. From the high temperature magnetic susceptibility measurements effective magnetic moment of manganese ions is determined which lies between the values for Mn3+ and Mn4+ ions.

AB  - Nanocrystalline hexagonal boron nitride powder (h-BN) was synthesized by sol-gel polycondensation of resorcinol and formaldehyde in the presence of boric acid followed by freeze drying. Pyrolysis and subsequent heat treatment of these cryogels resulted in formation of boron nitride powder. Characterization by nitrogen adsorption showed that precomposite cryogels and the BN powders were micro and mesoporous materials with high surface areas. Materials have been analyzed by means of X-ray diffraction, Raman scattering and electron microscopy methods. (C) 2010 Elsevier B.V. All rights reserved.

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.

AB  - This paper presents monitoring of changes during thermal shock and cavitation testing for low cement concrete that was synthesized and sintered at 1600 degrees C for 3h. Water quench test was applied as an experimental method for thermal stability testing. Image analysis of the samples showed some level of deterioration at the surface and inside the samples before water quench test. During the testing, the level of samples destruction was increasing. Damages inside the samples and at the surface during the water quench test were correlated to the number of quench experiments. Models based on the damage level of both the surface and inside the bulk were proposed for calculation of the strength degradation. Cavitation damages of the samples were induced by the modified vibratory cavitation set-up. Mass loss and surface erosion were determined during the experiment. The results indicated excellent thermal shock behavior and resistance to cavitation erosion. (c) 2010 Elsevier Ltd. All rights reserved.

AB  - The objective of the work is to study the effects of the high-energy milling on strengthening, thermal stability and electrical conductivity of Cu-Al2O3 composite. The prealloyed copper powders, atomized in inert gas and containing 3 wt. % Al, were milled up to 20 h in the planetary ball mill to oxidize in situ aluminium with oxygen from the air. Composite compacts were obtained by hot-pressing in an argon atmosphere at 800 degrees C for 3 h under the pressure of 35 MPa. The microstructural characterization was performed by the optical microscope, scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction analysis (XRD). The microhardness, electrical conductivity and density measurements were also carried out. The effect of internal oxidation and high-energy milling on strengthening of Cu-Al2O3 composite was significant, The increase of the microhardness of composite compacts (292 HV) is almost threefold comparing to compacts processed from the as-received Cu-3 wt. % Al powder (102 HV). The grain size of Cu-Al2O3 compacts processed from 5 and 20 h-milled powders was 75 and 45 nm, respectively. The small increase in the grain size and the small microhardness drop indicate the high thermal stability of Cu-Al2O3 composite during high-temperature exposure at 800 degrees C.

AB  - In this paper the nanosized non-oxide powders were prepared by carbothermal reduction and subsequent nitridation of diatomaceous earth which is a waste product from coal exploitation. Our scope was to investigate the potential use of diatomaceous earth as a main precursor for low-cost nanosized non-oxide powder preparation as well as to solve an environmental problem. The influence of carbon materials (carbonized sucrose, carbon cryogel and carbon black) as a reducing agent on synthesis and properties of low-cost nanosized nonoxide powders was also studied. The powders were characterized by specific surface area, X-ray and SEM investigations. It was found that by using diatomaceous earth it is was possible to produce either a mixture of non-oxide powders (Si(3)N(4)/SiC) or pure SiC powders depending on temperature.

As a starting material we used spinel (MgAl2O4)obtained by the modified glycine nitrate procedure (MGNP). Sintered products were characterized in terms Of phase analysis, densities, thermal shock, monitoring the damaged surface area in the refractory specimen during thermal shock and ultrasonic determination of the Dynamic Young modulus of elasticity. It was found that a new phase between yttria and alumina is formed, which improved thermal shock properties of the spinel refractories. Also densification of samples is enhanced by yttria addition.

AB  - The possibility of using Mg-exchanged zeolite as additive for densification of Si3N4 ceramic was studied. The zeolitic precursor was previously heated at 800 degrees C to obtain an amorphous powder with a composition corresponding to MgO center dot Al2O3-nSiO(2). The powder was mixed with Si3N4 and the sintering additive was homogenized by attrition milling in the presence of isopropanol and finally compacted by cold isostatic pressure. Pushrod dilatometry was used to measure the shrinkage behaviour of green bodies under a nitrogen atmosphere from room temperature to 1500 degrees C. The chemical reactions and phase evolution during pressureless sintering were also followed by means of X-ray and dilatometric analysis. Results show that the first liquid forms as low as 1070 degrees C, sharing in a significant reduction of sintering temperature. The final phase composition obtained at 1500 degrees C consist of crystalline alpha-Si3N4 phase which is emended in oxynitride glassy phase The results show that the Mg-exchanged zeolite is a very effective low-temperature sintering additive for silicon nitride.
