AB  - In this paper influence of alginate encapsulation on point of zero charge (pH pzc ) and thermodynamic properties of the natural and Fe(III)- modified zeolite were investigated. The pH pzc was determined by using 0.1000 g of the samples and 50 cm 3 of the solution containing KNO 3 in concentrations of 0.0001-0.01 mol/dm 3 for initial pH (pH i ) in range between 2 and 12. The obtained pH pzc were 6.2 for natural (NZA) and 6.5 for modified zeolite encapsulated with alginate (FeA). Influence of the temperature on the adsorption of lead was investigated for different initial lead ions concentrations (180-3200 mgPb 2+ /dm 3 ) and temperatures of 30, 40 and 60 o C. For both adsorbents, adsorption of lead ions increased with increasing its initial concentration as well as with increasing of the temperature. Also, the best fits of the experimental data were obtained by Freundlich isotherm. The temperature had positive influence adsorption and removal of lead ions increased with increasing its initial concentration as well as with increasing of the temperature. The thermodynamic parameters (the standard free energy of adsorption, standard enthalpy and standard entropy) were also determined. The results showed that lead ions removal from aqueous solutions is much favourable for FeA then NZA. © 2019 The Authors.

AB  - In present paper, the influence of the initial pH and concentration of Pb2+ on its adsorption by the natural (NZA) and Fe(III)-modified zeolite-alginate beads (FeA) was studied. Results showed that modification of the starting materials have a positive effect on their adsorption capacities (102 and 136 mg/g for the NZA and FeA, respectively). After encapsulation, the mechanism of lead adsorption by both adsorbents was changed and ion exchange dominates. The best adsorption was achieved for initial pH GT 3.8. Cation exchange capacity, structural properties, and hydrophobicity of samples were also determined, and the presence of the alginate has no significant influence on investigated properties of samples. Experiments on wastewater from tailings of lead and zinc mine Grot, Serbia, showed that after treatment with both adsorbents, the content of the most abundant heavy metals (Pb, Zn, Hg, and Mn) significantly decreased.

AB  - Alumina/YAG composites (AYX_t) with high relative density (99.2 %TD) were successfully obtained by mixing commercial alumina powder with different volume fractions of yttrium aluminium garnet (Y3Al5O12-YAG; 7, 14, 21 and 28). YAG was synthetized by nitrate glycine reaction in the form of precursor powder. Polycrystalline YAG powder was obtained by calcination at 950 degrees C for 2 h. Additionally, obtained compositions were characterized by XRD, SEM, EDX and electrochemical impedance spectroscopy. By XRPD analysis was found that the particle size of YAG powders lies in the nanometric range (being lower than 35 nm). By SEM microphotographs of composites were confirmed the formation of a conductive path consisting from mutually interconnected YAG particles. This was confirmed by the electrochemical impedance spectroscopy. The highest electrical conductivity of grain (K-g) and grain boundary (K-gb) at 700 degrees C amounted to 2.22x10(-2) ohm(-1)cm(-1) and 9.44x10(-3) ohm(-1) cm(-1), respectively, was measured in the composite containing 21 vol% of YAG.

AB  - The aim of this study was to investigate the biocompatibility of nanostructured materials based on highly active calcium silicates mixed with different radiocontrast agents in comparison to MTA+ using in vitro and in vivo model. Morphology of materials’ samples was analyzed using SEM while the phase compositions were identified by XRD. pH values of materials’ suspensions were conducted by pH-meter. The cytotoxicity of materials’ solutions was tested by MTT test (100, 50, 25 and 12.5 mg/ml). LDH and 3H-thymidine assay were utilized for biocompatibility investigations of materials’ eluates (24 h, 7 day and 21 day). Eighteen Guinea pigs were used for intramuscular implantation, as teflon tubes with freshly prepared materials were placed into intramuscular pockets. All samples were composed of round and needle-like particles equally distributed with Ca/Si ratio ~2.7 at%, with the presence of hydrated calcium silicate phases. The pH values of ALBO-MPCA1 and ALBO-MPCA2 were high alkaline, while in case of MTA+ they were lower and continuously declined (p < 0.05). Investigated materials didn’t exhibit dose-dependent effect on metabolic activity of L929 cells (p > 0.05). Significant differences in the percentage of cytotoxicity between diluted and undiluted extracts between all tested materials after 24 h and 7 day were noticed (p < 0.05). Increase in L929 cells proliferation was noticed in case of undiluted eluates of ALBO-MPCA1 and ALBO-MPCA2 after 7 day (p < 0.05). There were no statistically significant differences in the intensity of inflammatory response between investigated materials and control group after 60 day (p > 0.05). Evaluation of biocompatibility of both ALBO-MPCA1 and ALBO-MPCA2 indicate their potential clinical use.

AB  - In this work, plane tree seed-based activated carbons (AC) were used for possible application in carbon dioxide capture and storage (CCS) technology. After carbonization process at 850 degrees C, resulting preliminary ACs were activated at various temperatures. The high levels of the growth in basal planes of graphite structure in carbonized sample were detected. Also, it was found that the samples activated at 750 and 850 degrees C have a lower graphitization degree and contained substantially disordered sections and defects, which are characteristic of typical amorphous porous carbons. Process modeling has shown that the CO2 sorption can be described by multi-parametric continuous distributed reactivity model. Analysis showed the occurrence of gas reduction process, involving gibberellic acid and coenzymes which can produce the methane gas. The highly ordered arrangement of the gas molecules on the carbons was assumed. (C) 2017 Elsevier B.V. All rights reserved.

AB  - Calcium hydroxyapatite (CHA), as one of the most important ceramic materials in bone tissue engineering, was used as a delivery system for tigecycline, a potential antibiotic in treatment of osteomyelitis. Tigecycline, in a solid state, was mixed with CHA powder and the obtained mixture was compressed into tablets. The release of tigecycline from these tablets in a pH 7.4 phosphate-buffered saline solution was measured by a UV-vis spectrophotometer at 37 degrees C. The total dose of tigecycline was released for 5 to 30 days, depending on the applied pressure and drug concentration. A new drug release mechanism that determines the relationship between pore sizes and drug release rate is proposed. It explains and quantifies the drug release kinetics based on pore sizes and pore size distribution. (c) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

abstract = "Calcium hydroxyapatite (CHA), as one of the most important ceramic materials in bone tissue engineering, was used as a delivery system for tigecycline, a potential antibiotic in treatment of osteomyelitis. Tigecycline, in a solid state, was mixed with CHA powder and the obtained mixture was compressed into tablets. The release of tigecycline from these tablets in a pH 7.4 phosphate-buffered saline solution was measured by a UV-vis spectrophotometer at 37 degrees C. The total dose of tigecycline was released for 5 to 30 days, depending on the applied pressure and drug concentration. A new drug release mechanism that determines the relationship between pore sizes and drug release rate is proposed. It explains and quantifies the drug release kinetics based on pore sizes and pore size distribution. (c) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.",

AB  - A new approach to the two-level design and self-assembling of Me(x)SiO(y) (Me = Gd, Y and Ca or their mixtures) nano-powders from SiO(2) sols is described. The nanostructure design of various optical active materials based on different compounds of Me(x)Sio(y) is discussed. These particles were formed by the combination of hydrothermal synthesis and ultrasound spray pyrolysis. The morphology and structural design of the particles and sub-particles are defined by their synthesis procedure and processing parameters. The mean particle size and size distribution of all the Me(x)SiO(y) based compounds were determined by SEM analysis. These results were compared with the particle diameter evaluated from the theoretical model of the breaking-up of capillary waves. For all the synthesized powders, the obtained results indicate the possibility of a rigorous design of the structure of the particles throughout their entire hierarchy. (c) 2007 Elsevier B.V.

AB  - In this paper, the kinetics and sintering mechanism of hydro-thermally synthesized hydroxyapatite in the temperature range 900-1100 degrees C are presented. It was found that at 900 degrees C, the sintering process is very slow, whereas at 1000, 1050, and 1100 degrees C is much faster, caused by activated sintering with liquid phase/phase of solution on spots with concentrated material impurity and the formation of reaction/polyeutectic mixtures dominates. The activation energies of sintering were also determined. At all the investigated sintering temperatures, an approximate value of 90 kJ mol(-1) was found. (c) 2008 Elsevier B.V. All rights reserved.
