AB  - Iron oxide, in the form of magnetite (MG)–functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous WL was synthesized from calcium carbonate and siloxane by controlled sintering process using low molecular weight submicrosized poly(methyl methacrylate) as a pore-forming agent. The precipitation of MG nanoparticles was carried out directly by a polyol-medium solvothermal method or via branched amino/carboxylic acid cross-linker by solvent/nonsolvent method producing WL/MG and WL-?-APS/MG adsorbents, respectively. The structure/properties of MG functionalized WL was confirmed by applying FTIR, Raman, XRD, Mössbauer, and SEM analysis. Higher adsorption capacities of 73.126, 66.144, 64.168, and 63.456 mg g -1 for WL-?-APS/MG in relation to WL/MG of 55.450, 52.019, 48.132, and 47.382 mg g -1 for Cd 2+ , Ni 2+ , phosphate, and chromate, respectively, were obtained using nonlinear Langmuir model fitting. Adsorption phenomena were analyzed using monolayer statistical physics model for single adsorption with one energy. Kinetic study showed exceptionally higher pseudo-second-order rate constants for WL-?-APS/MG, e.g., 1.17–13.4 times, with respect to WL/MG indicating importance of both WL surface modification and controllable precipitation of MG on WL-?-APS. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - In this study, porous macro- and micro-cellular wollastonite-based ceramics was synthesized. A ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as a starting material. After 20 min of ultrasound treatment, and calcination at 250 degrees C for 30 min, different pore-forming agents were added to the as-obtained powders. Differential thermal analysis was used to determine characteristic temperatures of processes occurring within powders during heating. Based on the obtained results, the sintering regime was set up. The prepared mixtures were pressed into pallets and sintered at 900 degrees C. During the sintering regime, porous wollastonite-based ceramics was obtained. The phase composition of the sintered samples, as well as the microstructures, were analyzed by using X-ray diffraction and SEM. A two-phase system was detected in all samples, CaSiO3 wollastonite and Ca2SiO4 larnite, and their ratio varied with each pore-forming agent. It was observed that the addition of different pore-forming agents resulted in significantly different microstructures. In a batch test, the influence of pH, the contact time and the initial ion concentration on the adsorption efficiency of As+5, Cr(+6)and phosphate ions on the synthesized adsorbents were studied. Time-dependent adsorption is best described by the pseudo-second-order kinetic model and the Weber-Morris model, which predict intra-particle diffusion as a rate-controlling step of the overall process. High adsorption capacities, 21.93, 23.88, and 27.29 mg g(-1), were obtained for the CaCO3-siloxane-nanocellulose sorbent, and similar/lower capacities were obtained for the CaCO3-siloxane-PMMA and CaCO3-siloxane-cotton wool adsorbents.

AB  - The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. Different functional groups have been covalently attached on the MWCNTs sidewalls in order to induce interfacial interactions at nanofiller/polymer interface, which resulted in an improved nanomechanical features. Structural properties of nanocomposites, studied with XRD and Raman analysis, indicated the most pronounced decrease in a degree of amorphousness for samples containing 0.5 and 1 wt% of MWCNTs functionalized with dapsone (dapson-MWCNT) and diethyl malonate (dem-MWCNT). SEM and TEM micrographs confirmed improved dispersibility of the MWCNTs modified with aromatic structure of dapsone inside PMMA matrix. A significant increase in a glass transition temperature of over 60 degrees C has been found for the 1 wt% dapson-MWCNT nanocomposite. Additional modification of dapson-MWCNT by further increasing aromaticity and voluminosity of attached moiety (fid-MWCNT), showed 30 degrees C increases in a glass transition temperature at 4 wt% of nanofiller loading, which is similar to shift of 37 degrees C with loading of MWCNTs modified with ester terminal group. A maximum increase of 56% of reduced modulus and 86% of hardness was obtained for 1 wt% loading of dapson-MWCNT nanofiller. (C) 2016 Society of Plastics Engineers

AB  - Cordierite 2MgO+2Al2O3+5SiO2 is frequently used ceramic material, that is commonly used as a carrier of electrical components due to its low dielectric constant (~ 5), and low temperature thermal expansion coefficient (20•10-7 ºC-1). In order to accelerate the process of sintering, 5.00 mass% TeO2 was added to the starting mixtures. System was tested in two parallel mixtures, one with no added additives, and the other one with TeO2. The mechanical activation of the both mixtures was performed in a high-energy ball mill in time intervals from 0 to 40 min with ball to powder mass ratio 1:40. The particle size analysis (PSA) was employed in order to determine the changes in the particle size of the mechanically treated powders. The phase composition of the starting powders as well as microstructures was analyzed by the means of X-ray diffraction method and SEM.

AB  - In this study, highly porous macro- and micro-cellular wollastonite-based ceramics was synthesized. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, and calcination at 250 oC for 30 min, different pore-forming agents were added to the as-obtained powders. Differential thermal analysis was used to determine characteristic temperatures of processes occurring within powders during heating. Based on the obtained results, sintering regime was set up. Prepared mixtures were pressed into pallets and sintered at 900 oC. During the sintering regime, highly porous wollastonite-based ceramics was obtained. The phase composition of the sintered samples as well as microstructures was analyzed by the means of X-ray diffraction method and SEM. Two-phase system was detected in all samples, CaSiO3 wollastonite and Ca2SiO4 larnite, and their ratio varied with each pore-forming agent. It was observed that addition of different pore-forming agent resulted in significantly different microstructures.

AB  - Since cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2) (MAS), is a very useful high-temperature ceramic material, it is important to decrease its sintering temperature. In order to accelerate the process of sintering, 5.00 mass% MoO3 was added to the starting mixtures. The mechanical activation of the starting mixtures was performed in a high-energy ball mill in time intervals from 0 to 160 min. After the activation, starting mixtures were sintered at 1300 A degrees C for 2 h. In order to determine the impact of mechanical activation on particle size distribution and powders morphology, the mechanically treated powders were characterized by a laser light-scattering particle size analyzer and scanning electron microscopy. The phase composition of the starting mixtures and sintered samples was analyzed by the X-ray diffraction method. In order to determine temperature intervals of chemical reactions and phase transitions, differential thermal analyses (DTA) and thermo-gravimetric analysis were used. Kissingers equation was employed to calculate apparent activation energies of various processes that occur within the system during heating. Based on the obtained DTA results, it was established that mechanical activation along with MoO3 additive has influence on sintering temperature which was decreased for more than 100 A degrees C, comparing to the literature data.

AB  - The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a planetary ball mill. Green bodies were formed by an isostatic pressure of 300 MPa. The sintering of these samples was done either by the Two-Step Sintering (TSS) approach or by conventional pressureless sintering followed by Hot Isostatic Pressing (post-HIPing). The first set of compacts was sintered by TSS in air at 1300 degrees C for 30 min and the next step was performed at 1200 degrees C for 20 h. The density of the obtained samples after the two-step sintering reached almost 90% of the theoretical density (%TD). The second set of compacts was sintered at 1400 degrees C for 30 min in air. The samples without open porosity were post-sintered by the HIP at 1200 degrees C for 2 h in an argon atmosphere at a pressure of 200 MPa. The density significantly increased up to 96%TD. The differences between samples prepared by these two techniques were also analyzed by XRD and SEM. The lattice vibration spectra were obtained using Raman spectroscopy and they indicate a high degree of lattice disorder, as well as high values of the oxygen vacancy concentration. Electrical characteristic were established in the frequency range from 10 kHz to 10 GHz. The choice of the processing route had considerable influence on structural and physical properties of MgTiO3 ceramics. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Mechanically activated powders (0, 10, 40, 80 and 160 minutes) were formed by isostatic pressure 300 MPa to cylindrical green bodies (φ 12 mm). First set of samples was sintered at 1300°C for 30 min in air (heating rate 10 °C/min, cooling rate 5 oC/min). These samples were re-sintered at 1200 oC for 20 h in air (heating rate 20 °C/min, cooling rate 10 oC/min). Samples reached almost 90 % TD. The second set of samples was sintered at 1400 °C for 30 in air (heating rate 10 oC/min, cooling rate 5 °C/min). Relative densities increased up to 93 % TD. The samples of absence of open porosity (MTO-10, 40, 80 and 160) were post-sintered by pressure assisted technique Hot Isostatic Pressing (HIP) at 1200 °C for 2 h in argon atmosphere with pressure 200 MPa. The samples increased densities up to 96 % TD for sample MT-160. Electrical measurements were performed in the microwave field of frequency.

AB  - Fire protection coatings on steel constructions for outdoor conditions on the basis of organic solutions have been analyzed. The first layer of coating is corrosion protection, alkyd paint „PROTHERM STEEL PRIMEPOX“ manufactorer „ITALVIS PROTECT“ Italy. The second layer of coating is an expanding coat for outdoor conditions „PROTHERM STEEL (EXT)“ solvent-bazed, „AMONNFIRE“ Italy. The third layer is final colors for metal „AMOTHERM STEEL TOP PU SB“ „AMONNFIRE“ Italy. XRD, DTA/TG and FTIR methods were used for sample characterization. It was found that primary and outer layer had very good adhesion. The second layer, for fire protection possesses 2.5 mass % humidity, which resulted in decrease of adhesion. XRD and FTIR analysis showed that those materials are adequate materials for fire protection up to 1000°C. Principles of fire protection are based on chemical reaction that are taking place in the temperature range 400-700°C.

AB  - In this study, polyvinyl alcohol (PVA) nanofibers with ethyl vanillin as an active compound were prepared using electrospinning technique. The final products of electrospinning process were in the form of nanofibers films. PVA/ethyl vanillin nanofibers, having fibers diameters in the range 100-1700 nm, were successfully electrospun from ethanol/water mixture of PVA and ethyl vanillin. The effects of immobilization process on ethyl vanillin thermal properties were investigated by differential scanning calorimetry (DSC). The results of DSC showed significant influence of immobilization process on thermal properties of ethyl vanillin. It was noticed that melting point of immobilized ethyl vanillin was lower (similar to 55 A degrees C) compared to free flavor (similar to 77 A degrees C). Our results showed that films based on PVA/ethyl vanillin nanofibers are mechanically stable.

AB  - Cordierite, 2MgO•2Al2O3•5SiO2 (MAS), is high-temperature ceramic material. Cordierite is commonly used material because of outstanding electrical properties, low temperature expansion coefficient and low dielectric constant. In order to accelerate the process of sintering, 5.00 mass% MoO3 has been added to the starting mixtures. The mechanical activation of the starting mixtures was performed in a high energy ball mill during 0-160 minutes. All starting mixtures were sintered at 1100°C, 1200°C and 1300°C for 2h. The particle size analysis (PSA) was employed in order to determine the changes in the particle size of the mechanically treated powders. The phase composition of the starting powders was analyzed by the X-ray diffraction method. Differential thermal (DTA) and thermogravimetric (TG) analysis were used in order to determine characteristic temperatures within the system during heating. Based on the obtained DTA results, it was established that mechanical activation with additive MoO3, has influence on decreasing sintering temperatures for about 150°C.

AB  - The aim of this paper was investigation of structural and electrical properties of magnesium titanate ceramic obtained mechanochemically and subjected to two stage sintering process. Mixtures of MgO and TiO2 were treated in a planetary ball mill for several time intervals ranging from 0 to 160 minutes. Powders prepared in this way were two stage sintered, at 1400 °C in air in the first stage, and then post-sintered by pressure assisted technique Hot Isostatic Pressing (HIP) at 1280 °C in argon atmosphere with a pressure of 200 MPa. X-ray diffraction was performed in order to established phase composition of obtained ceramics. Densities of sintered samples were measured by Archimedes method. The values of density were over 96 % of theoretical one and pure MgTiO3 phase was observed. Morphology of sintered bodies was investigated by SEM, and micrographs indicate the final sintering stage and very dense ceramics. Electrical measurements were performed in the microwave field of frequency.

AB  - Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400ºC). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier sintering process at lower temperature. The influence of MoO3 on the preparation process of cordierite ceramics was investigated. 2MgO-2Al2O3-5SiO2 was researched by sintering followed binary systems: MgO/MoO3, Al2O3/MoO3 and SiO2/MoO3 (all sintered at 850ºC and 1100ºC, sintering time 2h). Composition of these systems was 80% of oxide and 20% MoO3. The effects of sintering, the composition and morphology were followed by X-ray diffraction, SEM microscopy and EDS analysis. It has been found that MoO3, beside liquid phase, forms intermediary unstable compounds with MgO and Al2O3, which is the significance information for further research. MAS ceramics were sintered with 20% MoO3 at 1100ºC, 1200ºC and 1300ºC, during 2h.

AB  - The aim of this study was to investigate the Cs+ ions sorption on natural minerals clinoptilolite. The analysis of clinoptilolite and clinoptilolite with adsorbed Cs+ ion was conducted by X-ray diffraction, scanning electron microscopy, X-ray fluorescence, and gamma spectrometry. The specific activity of naturally occurring radionuclides in clinoptilolite was determined by gamma spectrometry by using the HPGe semiconductor detector. Obtained activity concentrations ranged from 49 Bq/kg to 810 Bq/kg for K-40, 5.7 Bq/kg to 10 Bq/kg for U-238, 5.8 Bq/kg to 70 Bq/kg for Th-232(Ac-228), and the presence of artificial radionuclides was not detected (Cs-137 LT 0.02 Bq/kg). The study of the thermal decomposition of raw clinoptilolite and Cs adsorbed clinoptilolite by differential thermal analysis is presented in this paper. The activation energy of the reaction phase transformation of raw clinoptilolite is 156.7 kJ/mol, while Cs adsorbed clinoptilolite is 121.7 kJ/mol. The lower value of activation energy reaction of the phase transformation Cs adsorbed clinoptilolite indicates that Cs which is adsorbed destabilizes the crystal structure of clinoptilolite and thus facilitates the transition to the amorphous state.

AB  - In this article, the advantages of combined sintering in comparison with the conventional one, of mechanically activated magnesium titanate ceramic were investigated. The stoichiometric mixtures of MgO and TiO2 were mechano-chemically activated for 0, 10, 40, 80 and 160 minutes by ball milling and then isostatically pressed (CIP) to form green bodies. Conventional sintering was realized by heating up to 1400 degrees C and hold for 30 minutes in air atmosphere. Resulting ceramic samples with closed porosity were post-sintered by pressure assisted technique Hot Isostatic Pressing (HIP) at 1280 degrees C/3h in argon atmosphere with a pressure of 200 MPa. The best results were observed in the case of samples post-sintered by HIP, when single-phase MgTiO3 samples with relative density of 96% were prepared.

abstract = "In this article, the advantages of combined sintering in comparison with the conventional one, of mechanically activated magnesium titanate ceramic were investigated. The stoichiometric mixtures of MgO and TiO2 were mechano-chemically activated for 0, 10, 40, 80 and 160 minutes by ball milling and then isostatically pressed (CIP) to form green bodies. Conventional sintering was realized by heating up to 1400 degrees C and hold for 30 minutes in air atmosphere. Resulting ceramic samples with closed porosity were post-sintered by pressure assisted technique Hot Isostatic Pressing (HIP) at 1280 degrees C/3h in argon atmosphere with a pressure of 200 MPa. The best results were observed in the case of samples post-sintered by HIP, when single-phase MgTiO3 samples with relative density of 96% were prepared.",

AB  - Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400 degrees C). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier sintering process at lower temperature. The influence of MoO3 on the preparation process of cordierite ceramics was investigated. 2MgO-2Al(2)O(3)-5SiO(2) was researched by sintering followed binary systems: MgO/MoO3, Al2O3/MoO3 and SiO2/MoO3 (all sintered at 850 degrees C and 1100 degrees C, sintering time 2h). Composition of these systems was 80 mass% of oxide and 20 mass% MoO3. The effects of sintering, the composition and morphology were followed by X-ray diffraction and SEM microscopy. It has been found that MoO3, beside liquid phase, forms intermediary unstable compounds with MgO and Al2O3, which is the significance information for further research. MAS ceramics were sintered with 20 mass% MoO3 at 1100 degrees C, 1200 degrees C and 1300 degrees C, during 2h.

AB  - Strontium-titanate powder was mechanically activated in a planetary ball mill for 0, 5, 10, 30, 60, 90 and 120 minutes. Non-isothermal sintering of non-activated and activated SrTiO3 powder samples in the temperature interval from 50 to 1300 0C with three different heating rates (10, 15 and 20 0C/min) was investigated on a dilatometer. X-ray powder diffraction and scanning electron microscopy (SEM) were used to determine the phase composition, lattice microstrains and microstructure morphology of the samples. XRD results showed the presence of new phases: SrCO3 (strontuim-carbonate) and TiO2 (anatase) after 30 minutes of  mechanical activation.

AB  - According to its low temperature thermal expansion coefficient, low dielectric constant, also good mechanical properties, cordierite, 2MgO×2Al2O3×5SiO2, represents a very attractive hightemperature ceramic material. In this study, cordierite was prepared by solid state reaction of the MgO, Al2O3 and SiO2 mixture. One of the components from the mixture, SiO2, was mechanically activated in a high energy ball mill during 5 and 10 minutes. The applied pressure before the sintering process was 2 t/cm2. Sintering process of mixtures containing non-activated and activated SiO2 powder was performed at 1350 oC for 4h in the air atmosphere. The phase composition of starting oxides and sintered samples was analyzed by the X-ray diffraction method. Particle size analysis was performed to investigate the differences between starting components. Scanning electron microscopy was done to analyze the microstructure of both components and sintered samples. This paper investigates the influence of one mechanically activated SiO2 component on the densities of green bodies as well as on the sintered samples, along with electrical properties of cordierite ceramics.
