AB  - This paper presents a class of integer codes capable of correcting single asymmetric errors. The presented codes are defined over the ring of integers modulo 2b– 1 and are constructed with the help of a computer. The results of an exhaustive search have shown that, for practical lengths up to 4096 bits, the proposed codes use the same number of check bits as the best systematic single asymmetric error-correcting codes (SAECCs). Besides this, it is found that for some lengths the presented codes are perfect. Finally, the paper shows that the encoding/decoding complexity of the proposed codes is notably lower than that of the best systematic SAECCs.

AB  - Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared mixture was thermally processed at 300 oC for 6 h. Sintering at 1300 oC for 1 h resulted in a mixture of different phases, BaTiO3, BaFe12O19 and Ba12Ti28Fe15O84, which were confirmed by x-ray powder diffraction. A dense microstructure with a small volume fraction of closed porosity was indicated by the scanning electron microscopy, while a homogeneous distribution of Fe ions over BaTiO3 phase was visible from energy dispersive spectroscopy mapping. Doping of BaTiO3 with Fe2O3 resulted in formation of magnetic hexaferrite phases, as confirmed by dielectric measurements that showed a broadened maximum of the permittivity measured as a function of temperature.

AB  - Moving from fossil fuels toward renewable resources of energy has a worldwide consensus. Solar energy alone can satisfy all our energy requirements since the earth receives 725 ZJ of energy from the sun each year while total human energy consumption in 2019 was 0.584 ZJ. The 2010s are highlighted as a transitional decade when the photovoltaic conversion industry transformed from a subsidized to a profitable energy sector. While photovoltaic energy conversion is a clean process, technologies for producing photovoltaic materials and solar panels affect the environment. The utilization of photovoltaic materials with low impact on the environment during the entire life cycle will mark the beginning of the sustainable transition toward 100% clean renewable energy sources in a sustainable manner. Thus far, only perovskite compounds have the potential to satisfy these requirements because of their theoretical conversion efficiencies, ease of synthesis, production scalability, adaptability, and comparability to existing photovoltaic systems. In this article, the rise of the photovoltaic industry in the last decade is shown and requirements in further transition from renewable to clean sources of renewable energy are foreseen.

AB  - Electrochemical and structural properties of LiV2O5 cathode were investigated. Obtained by solid state reaction at high temperature the material crystallized as gamma polymorph phase, γ-LiV2O5. The gamma structure provides two crystallographic sites to accommodate lithium ions, Li1 and Li2 position. Lithium insertion at these two sites occurs at two respective voltages versus lithium metal: ~3.6 V (Li1) and ~2.4 V (Li2). Intercalation at Li1 position is reversible in both organic and aqueous electrolyte and provides stable cycling performance at the high voltage. On the contrary, sluggish insertion/removal of Li+ at Li2 sites causes unstable performance and significant storage capacity fade at lower voltages. Lithium diffusion 3d landscape was determined by bond valence calculations applied on the γ-LiV2O5 phase, as well as on the metastable phases of γ′-V2O5 and ζ-Li2V2O5 that exist at high and low voltages respectively. The model was proposed based on inactivity of Li2 position of the metastable ζ-Li2V2O5 phase which provides explanation for the observed storage capacity loss at low voltages.

AB  - The properties (densities of electrons and metastable argon atoms, effective electron temperature and dust charge) of argon/dust and pure argon pulsed plasmas are studied using a spatially-averaged model. The calculated time-dependencies for the densities of electrons and metastable atoms are compared with the experimental measurements and are found to be in a good qualitative agreement. It is analyzed how the plasma properties depend on the shape of the electron energy probability function (EEPF), the pulsing frequency and the duty cycle for both dust-free and dusty plasma. The analysis reveals that the agreement between theory and experiment is better with Druyvesteyn EEPF than the Maxwellian EEPF. Further, the variation in the pulsing frequency νp differently affects the metastable density nm in a dust-free and in a dusty plasma. For large νp, the metastable density in the dust-free pulsed plasma is larger than in the continuous-wave (CW) discharge, while the opposite is obtained in the presence of dust particles. This difference probably arises because of faster variation in the effective electron temperature in the dusty plasma due to collection of electrons by dust particles. Our calculations also show that dust particles may affect the behavior of electron density in the beginning of the on-period due to an enhancement in electron collection by dust particles.

It is analyzed how the plasma properties depend on the shape of the electron energy probability function (EEPF), the pulsing frequency and the duty cycle for both dust-free and dusty plasma. The analysis reveals that the agreement between theory and experiment is better with Druyvesteyn EEPF than the Maxwellian EEPF. Further, the variation in the pulsing frequency νp differently affects the metastable density nm in a dust-free and in a dusty plasma. For large νp, the metastable density in the dust-free pulsed plasma is larger than in the continuous-wave (CW) discharge, while the opposite is obtained in the presence of dust particles. This difference probably arises because of faster variation in the effective electron temperature in the dusty plasma due to collection of electrons by dust particles. Our calculations also show that dust particles may affect the behavior of electron density in the beginning of the on-period due to an enhancement in electron collection by dust particles.",

AB  - This paper presents a class of integer codes capable of correcting single asymmetric errors. The presented codes are defined over the ring of integers modulo 2b– 1 and are constructed with the help of a computer. The results of an exhaustive search have shown that, for practical lengths up to 4096 bits, the proposed codes use the same number of check bits as the best systematic single asymmetric error-correcting codes (SAECCs). Besides this, it is found that for some lengths the presented codes are perfect. Finally, the paper shows that the encoding/decoding complexity of the proposed codes is notably lower than that of the best systematic SAECCs.

AB  - The polyanion cathodes for Li-ion batteries, namely LiFePO4, Li2FeP2O7 and Li2FeSiO4, were synthesized by very short high-temperature treatment (approximately several minutes) and subsequent quenching. Methylcellulose—a polymer with thermally driven water solubility—was used as the medium in which the precursor solutions were dispersed prior to high temperature treatment. The methylcellulose pyrolytically decomposes to carbon, thus producing the polyanion material/carbon composites of LiFePO4/C, Li2FeP2O7/C and Li2FeSiO4/C. The obtained powders have reduced crystallinity and significant microstructural characteristics: low crystallite size and notable microstrain. They exhibit stable electrochemical performances in both aqueous and organic electrolyte. The broadening of existing peaks in cyclic voltammetry and/or the emergence of new broad peaks was attributed to the presence of the amorphous phase in the samples. In galvanostatic charge–discharge tests, the materials provided high capacities at low current densities, while the highest rate performance was demonstrated by olivine-phosphate when compared to the other two materials.

AB  - The properties (densities of electrons and metastable argon atoms, effective electron temperature and dust charge) of argon/dust and pure argon pulsed plasmas are studied using a spatially-averaged model. The calculated time-dependencies for the densities of electrons and metastable atoms are compared with the experimental measurements and are found to be in a good qualitative agreement. It is analyzed how the plasma properties depend on the shape of the electron energy probability function (EEPF), the pulsing frequency and the duty cycle for both dust-free and dusty plasma. The analysis reveals that the agreement between theory and experiment is better with Druyvesteyn EEPF than the Maxwellian EEPF. Further, the variation in the pulsing frequency νp differently affects the metastable density nm in a dust-free and in a dusty plasma. For large νp, the metastable density in the dust-free pulsed plasma is larger than in the continuous-wave (CW) discharge, while the opposite is obtained in the presence of dust particles. This difference probably arises because of faster variation in the effective electron temperature in the dusty plasma due to collection of electrons by dust particles. Our calculations also show that dust particles may affect the behavior of electron density in the beginning of the on-period due to an enhancement in electron collection by dust particles.

AB  - Although selenium nanoparticles (SeNPs) have gained attention in the scientific community mostly through investigation of their anticancer activity, a great potential of this nanomaterial was recognized recently regarding its antimicrobial activity. The particle form, size, and surface chemistry have been recognized as crucial parameters determining the interaction of nanomaterials with biological entities. Furthermore, considering a narrow boundary between beneficial and toxic effects for selenium per se, it is clear that investigations of biomedical applications of SeNPs are very demanding and must be done with great precautions. The goal of this work is to evaluate the effects of SeNPs surface chemistry and structure on antimicrobial activity against several common bacterial strains, including Staphylococcus aureus (ATCC 6538), Enterococcus faecalis (ATCC 29212), Bacillus subtilis (ATCC 6633), and Kocuria rhizophila (ATCC 9341), as well as Escherichia coli (ATCC 8739), Salmonella Abony (NCTC 6017), Klebsiella pneumoniae (NCIMB 9111) and Pseudomonas aeruginosa (ATCC 9027), and the standard yeast strain Candida albicans (ATCC 10231). Three types of SeNPs were synthesized by chemical reduction approach using different stabilizers and reducing agents: (i) bovine serum albumin (BSA) + ascorbic acid, (ii) chitosan + ascorbic acid, and (iii) with glucose. A thorough physicochemical characterization of the obtained SeNPs was performed to determine the effects of varying synthesis parameters on their morphology, size, structure, and surface chemistry. All SeNPs were amorphous, with spherical morphology and size in the range 70–300 nm. However, the SeNPs obtained under different synthesis conditions, i.e. by using different stabilizers as well as reducing agents, exhibited different antimicrobial activity as well as cytotoxicity which are crucial for their applications. In this paper, the antimicrobial screening of the selected systems is presented, which was determined by the broth microdilution method, and inhibitory influence on the production of monomicrobial and dual-species biofilm was evaluated. The potential mechanism of action of different systems is proposed. Additionally, the cytotoxicity of SeNPs was examined on the MRC-5 cell line, in the same concentration interval as for antimicrobial testing. It was shown that formulation SeNPs-BSA expressed a significantly lower cytotoxic effect than the other two formulations.

The goal of this work is to evaluate the effects of SeNPs surface chemistry and structure on antimicrobial activity against several common bacterial strains, including Staphylococcus aureus (ATCC 6538), Enterococcus faecalis (ATCC 29212), Bacillus subtilis (ATCC 6633), and Kocuria rhizophila (ATCC 9341), as well as Escherichia coli (ATCC 8739), Salmonella Abony (NCTC 6017), Klebsiella pneumoniae (NCIMB 9111) and Pseudomonas aeruginosa (ATCC 9027), and the standard yeast strain Candida albicans (ATCC 10231). Three types of SeNPs were synthesized by chemical reduction approach using different stabilizers and reducing agents: (i) bovine serum albumin (BSA) + ascorbic acid, (ii) chitosan + ascorbic acid, and (iii) with glucose. A thorough physicochemical characterization of the obtained SeNPs was performed to determine the effects of varying synthesis parameters on their morphology, size, structure, and surface chemistry. All SeNPs were amorphous, with spherical morphology and size in the range 70–300 nm. However, the SeNPs obtained under different synthesis conditions, i.e. by using different stabilizers as well as reducing agents, exhibited different antimicrobial activity as well as cytotoxicity which are crucial for their applications. In this paper, the antimicrobial screening of the selected systems is presented, which was determined by the broth microdilution method, and inhibitory influence on the production of monomicrobial and dual-species biofilm was evaluated. The potential mechanism of action of different systems is proposed. Additionally, the cytotoxicity of SeNPs was examined on the MRC-5 cell line, in the same concentration interval as for antimicrobial testing. It was shown that formulation SeNPs-BSA expressed a significantly lower cytotoxic effect than the other two formulations.",

AB  - Monitoring the occurrence and rate of corrosion, the formation of thermal oxides on the surface of metal parts of the power plant, as well as the method of their elimination in a way that is technologically suitable, economically affordable and environmentally justified is shown in this technical solution. It has been established that the metal elements affected by corrosion were made from stainless steel AISI 304. Accordingly, the occurrence of corrosion and thermal oxides was monitored based on the material and the composition of the dust with which the metal parts are in contact. The emergence of thermal oxides on the surface of stainless steels is a consequence of the elevated temperature at the welding site.
The pH value of both solutions was measured: standard and saturated solution of dust from the plant. The composition of the dust samples was determined by FTIR. The other tests were defined based on the ions present in the solution.
The corrosion potential, the value of the polarization resistance, as well as the corrosion current density were determined. All tests of stainless steel in the standard solution and in the saturated solution of dust were performed for one hour within a span of 25 days.
Technological recommendations on how to eliminate corrosion and thermal oxides are provided.
The solution has been applied since January 2021 by ELNOS BL d.o.o.

AB  - Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies were obtained depending on the annealing temperature: hexagonal layeredα-Na0.7MnO2.05 nanoplates were obtained at 850 ◦C, while 3-D tunnel structured Na0⋅4MnO2 and Na0⋅44MnO2, both with rod-like morphology, were obtained at 800 ◦C and 900 ◦C, respectively. The investigations of the electrochemical behavior of obtained cathodic materials in aqueous NaNO3 solution have shown that Na0⋅44MnO2 obtained at 900 ◦C has shown the best battery performance. Its initial discharge capacities are 123.5 mA h/g, 113.2 mA h/g, and 102.0 mA h/g at the high current densities of 1000, 2000 and 5000 mA/g, respectively.

AB  - Treatment of liquid aluminum alloys in low vacuum conditions is often applied for parts production in the automotive and aerospace industry because of its effectiveness in removing dissolved gases. Because of the low vapour pressure of aluminum, concentrations of the most unwanted elements can be significantly reduced at lower pressures. Presented work analyzing kinetics parameters for elemental evaporation from liquid Al7Si4Cu alloy. The pressure inside mullite refractory material was below 2.1 kPa for melt temperatures between 760 and 910 °C. The alloy’s chemical composition was characterized by the Inductively Coupled Plasma Mass Spectrometry method. Lead, Zinc, and Mercury were reduced at the highest rate while the lowest evaporation occurred for key alloying elements such as Silicon and Copper. Higher evaporation rates were achieved at higher temperatures. The evaporation ratios, volatility coefficients, reaction rate constants, mass transfer coefficients, and elemental evaporation susceptibility on temperature increase were deduced for 16 elements. The obtained results confirmed that keeping molten aluminum alloys in low vacuum conditions for one hour is an efficient method in removing unwanted elements with great potential for further improvement in industrial conditions.

AB  - Ekološki izvori energije i ekonomične metode prečišćavanja vode i vazduha velika supotreba današnjeg tehnološki razvijenog sveta. Fotoaktivni materijali mogu da obezbede ekološkualternativu fosilnim gorivima kada je u pitanju proizvodnja energije i omoguće saniranje nastalihpromena u životnoj sredini. Naime, fotoaktivni materijali apsorbuju svetlost i tada dolazi dopobuđivanja elektrona, koji su odgovorni za prenos električne struje ili učestvuju u procesurazgradnje zagađujućih materija. Postoji veliki broj fotoaktivnih materijala, među kojima se izdvajaTiO2, kojeg odlikuje hemijska inertnost, otpornost na fotoindukovanu i hemijsku koroziju inetoksičnost. Na fotoaktivnost TiO2 utiču mnogi faktori, kao što su morfologija, kristalna struktura istepen rekombinacije nosilaca naelektrisanja.Cilj ove doktorske disertacije je poboljšanje fotokatalitičke i fotoelektrične aktivnosti TiO2nanocevi. U tu svrhu, TiO2 nanocevi su sintetisane metodom elektrohemijske anodizacije pločicetitana. Ispitivan je uticaj procesnih parametara anodizacije na morfologiju i fotokatalitičku aktivnostnanocevi TiO2 u procesu razgradnje boje. Utvrđeno je da sa porastom napona anodizacije rastuvisina i prečnik nanocevi, što utiče na pomeraj apsorpcione granice ka vidljivom delu spektra i napoboljšanje fotokatalitičke aktivnosti. Određen je uticaj temperature žarenja na kristalnu strukturu,morfologiju i fotokatalitičku aktivnost TiO2 nanocevi. Žarenjem nanocevi na 450 °C dobijena jekristalna modifikacija anatasa sa veoma malim sadržajem faze rutila. Sa daljim porastomtemperature žarenja (600 i 650 °C) uočeno je prisustvo obe faze, anatasa i rutila, u različitimodnosima, a do kompletne transformacije anatasa u rutil došlo je na 700 °C. Pored promenekristalne strukture, uočen je uticaj temperature žarenja na morfologiju nanocevi. Sa povišenjemtemperature žarenja, visina nanocevi se smanjivala, kao i poroznost nanocevi, da bi na 700 °C došlodo kolapsa nanocevne morfologije. Sagledan je uticaj kristalne strukture i morfologije TiO2nanocevi na fotokatalitičku razgradnju boje metil-oranž. Zaključeno je da istovremeno prisustvoanatasa i rutila obezbeđuje bolju fotokatalitičku aktivnost u odnosu na čist anatas i čist rutil.Kako bi se ispitao uticaj dopiranja TiO2 azotom na fotokatalitičku aktivnost, nanocevi TiO2su žarene u atmosferi amonijaka, na temperaturi od 450 °C, pri različitim dužinama žarenja.Ispitivan je uticaj vremena žarenja na količinu i vrstu dopiranja. Uočeno je da žarenje u atmosferiamonijaka, pri različitim vremenima, nije uticalo na morfologiju nanocevi. Hemijska analizapovršine TiO2 nanocevi rendgenskom fotoelektronskom spektroskopijom pokazala je da sa dužimvremenom žarenja opada ukupan sadržaj azota u nanocevima. Osim toga, dužina žarenja uamonijaku je uticala i na prirodu inkorporiranja azota u TiO2. Pri kraćem vremenu žarenja zapaženje veći sadržaj intersticijskog azota, a manji sadržaj supstitucijskog azota. S dužim vremenomžarenja u amonijaku, sadržaj intersticijskog azota opada, dok sadržaj supstitucijskog raste.Apsorpcioni spektri su pokazali da uzorak sa najvećom količinom azota i najvećim sadržajemintersticijskog azota pokazuje najveći pomeraj granice apsorpcije ka većim talasnim dužinama.

AB  - Environmental friendly power sources and cost-effective methods for water and airpurification, are a necessity in modern technologically developed world. Photoactive materials canprovide an environmentally friendly alternative to fossil fuels in power production and enable theremediation of changes in the environment. Namely, photoactive materials absorb light, whichexcites electrons that are responsible for generating electricity or participate in the process ofdecomposition of pollutants. There are a large number of photoactive materials, among which TiO2has attracted particular attention, due to its chemical inertness, resistance to photo and chemicalcorrosion and non-toxicity. The photoactivity of TiO2 depends on many factors, such asmorphology, crystal structure and the degree of recombination of charge carriers.The aim of this doctoral dissertation is to improve the photocatalytic and photoelectricactivity of TiO2 nanotubes. For this purpose, TiO2 nanotubes were synthesized by theelectrochemical anodization of a titanium plate. The influence of the anodization process parameterson the morphology and photocatalytic activity of TiO2 nanotubes for color degradation wasinvestigated. It was found that an increased anodization voltage leads to increased heights anddiameters of nanotubes, causing the shift of the absorption limit towards the visible part of thespectrum and the improvement of the photocatalytic activity. The influence of the annealingtemperature on the crystal structure, morphology and the photocatalytic activity of TiO2 nanotubeswas determined. The anatase crystalline modification with a very low rutile phase content wasobtained by annealing nanotubes at 450 °C. When the annealing temperature was further increased(600 and 650 °C), the presence of both phases, anatase and rutile, was observed in different ratios,and the complete transformation of anatase to rutile occurred at 700 °C. Besides the change in thecrystal structure, the influence of the annealing temperature on the morphology of the nanotubeswas observed as well. As the annealing temperature increased, the height and porosity of nanotubesdecreased, so that the nanotube morphology collapsed at 700 °C. The influence of the crystalstructure and morphology of TiO2 nanotubes on the photocatalytic degradation of methyl-orangewas observed. It was concluded that the simultaneous presence of anatase and rutile provides betterphotocatalytic activity than pure anatase and pure rutile.In order to investigate the effect of nitrogen doping of TiO2 on photocatalytic activity, TiO2nanotubes were annealed in an ammonia atmosphere, at a temperature of 450 °C, for differentannealing times. The influence of the annealing time on the amount and type of doping wasinvestigated. It was observed that annealing in an ammonia atmosphere, for different periods, didnot affect the morphology of nanotubes. A chemical analysis of the surface of TiO2 nanotubes by Xray photoelectron spectroscopy showed that the total nitrogen content in nanotubes decreased withlonger annealing times. In addition, the annealing duration in ammonia also influenced the nature ofnitrogen incorporation into TiO2. With a shorter annealing time, a higher content of interstitialnitrogen and a lower amount of substitution nitrogen were observed. With a longer annealing timein ammonia, the amount of interstitial nitrogen decreased, while the substitution nitrogen increased.The absorption spectra showed that the sample with the highest amount of nitrogen and the highestcontent of interstitial nitrogen showed the largest shift towards higher wavelengths. The sameapplies to the photocatalytic efficiency. The greatest photocatalytic degradation of the dye wasachieved in the sample annealed in ammonia for the shortest time.Further research was directed towards expanding the knowledge of individual and combinedeffects of nitrogen doping and deposition of the quantum dots of inorganic sensors on thephotocatalytic activity of TiO2 nanotubes. It was observed that the deposition of CdS quantum dotsdid not affect the morphology of nanotubes, but in some places agglomeration of CdS nanoparticlesoccurred, due to which nanotube openings closed. The photocatalytic efficiency of nitrogen-dopednanotubes was improved after CdS nanoparticle deposition.

AB  - Barium titanate (BaTiO3) attracts high scientific and technological attention due to good dielectric and electromechanical properties. Although BaTiO3 is one of the most frequently investigated ferroelectric materials, the need for finding new and/or improved synthesis methods of this material still exists. In this paper, a novel, mild synthesis route for producing tetragonal BaTiO3 from barium nitrate and Ti-oxalate precursor is presented. Morphology of the prepared and subsequently sintered BaTiO3 was determined by SEM. Particle size distribution of the as prepared powder was monitored by the laser diffraction. The phase composition, structure and lattice dynamics were investigated by XRD and Raman spectroscopy. Finally, dielectric parameters were determined in the temperature range from 30 to 180 degrees C, and within a variety of frequencies. Curie temperature was detected at 130 degrees C.

AB  - The influence of mechanical activation on the formation, sintering kinetics and morphology was investigated in sintered barium strontium titanate (BST) ceramics with different Ba-to-Sr ratios. Initial powders were mechanically activated for 20 and 120 min, leading to mechano-chemical reaction and formation of BaxSr1-xTiO3 phases. Agglomeration was found to represent an important factor in the process of formation of BaxSr1-xTiO3 phases around 800 oC and during sintering. It reduces the effectiveness of mechanical activation on formation of BaxSr1-xTiO3 phases beyond the short period (20 min), while in the process of sintering, prolonged mechanical activation (120 min) leads to a significant reduction in sintering temperature and the corresponding value of activation energy. In addition, all three systems show a phase transformation around 1100 oC, attributed to the hexagonal-to-cubic phase transition. Morphology of the final sintered ceramics can be correlated primarily with the state of the pre-sintered powder, where mechanically activated powders with smaller particle size produced more compact and less porous final product.

AB  - Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, novel porous amine-functionalized silicate minerals, specifically, cordierite was investigated for the removal of toxic heavy metals from industrial wastewaters. Cordierite supports were synthesized by mixing MgO, Al2O3 , and SiO2 powders in 2:2:5 molar ratios, and mechanically activated via ball milling in ethanol for 10, 40, or 80 min. Pellets were sintered by heating in air at 20°C min-1 to 1,350°C, for 2 h. Porous supports were produced by coarsely crushing the sintered pellets and mixing the crushed and sieved cordierite powder with 20 wt.% of a pore-forming agent, either nanocellulose or yeast. The resulting pellets were sintered by heating at 5°C min-1 to 700°C in air. The synthetic cordierite support was modified by treatment in poly-ethylenimine. Activated supports were then tested for the removal of Ni2+ and Cd2+ ions. The phase composition of the cordierite supports was analyzed by the X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy. Analysis of adsorption isotherms, kinetics, and thermodynamic parameters indicated that adsorption was a spontaneous, endothermic process with a maximum adsorption capacity of 36 mg g-1 for Cd2+ and 43 mg g-1 for Ni2+. This work has shed light on the mechanism of heavy metal removal from the aquatic medium using the novel hybrid functionalized cordierite-based ceramic.

abstract = "Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, novel porous amine-functionalized silicate minerals, specifically, cordierite was investigated for the removal of toxic heavy metals from industrial wastewaters. Cordierite supports were synthesized by mixing MgO, Al2O3 , and SiO2 powders in 2:2:5 molar ratios, and mechanically activated via ball milling in ethanol for 10, 40, or 80 min. Pellets were sintered by heating in air at 20°C min-1 to 1,350°C, for 2 h. Porous supports were produced by coarsely crushing the sintered pellets and mixing the crushed and sieved cordierite powder with 20 wt.% of a pore-forming agent, either nanocellulose or yeast. The resulting pellets were sintered by heating at 5°C min-1 to 700°C in air. The synthetic cordierite support was modified by treatment in poly-ethylenimine. Activated supports were then tested for the removal of Ni2+ and Cd2+ ions.

AB  - The aim of the study was to investigate the influence of low heating temperatures with two different retention times to optimize the process for obtaining nanosized hydroxyapatite material that can possibly be used in the fields of biology and pharmacy. Nanosized hydroxyapatite was successfully obtained by wet chemical precipitation. The annealing of the material performed at 300 oC with two different retention times i.e. 3 and 6 hours in air atmosphere. Low annealing temperature with extended retention time was selected in terms to reduce energy consumption. FTIR spectroscopy was used to confirm characteristic vibrational bands of hydroxyapatite samples, and presence of carbonate bands of hydroxyapatite annealed for 3h and 6h. X-Ray powder diffraction analysis were used to examine phase composition, determine the size of unit cells and crystallite sizes, and SEMEDS methods were used to obtain particle size and arrangement also grain growth morphology and confirmed the presence of calcium, phosphorous oxygen and carbonate peaks. The results show that different retention time has influence on particle growth as well as unit cell parameters and crystallite sizes changes of hydroxyapatite material.

AB  - Tetrahydropyrimidines are a class of azaheterocycles, also called Biginelli hybrids (obtained from the Biginelli reaction), that have attracted an enormous interest in the medicinal chemistry community in recent years, due to a broad biological activity, such as anticancer, antiviral, anti-inflammatory, antidiabetic, antituberculosis activities, etc. According to SciFinder®, more than 70 000 different Biginelli-like compounds have been covered in publications. However, although the Biginelli reaction can yield a large number of compounds with a broad range of activities, none of them have been captured in a carrier. In this study, chitosan-based (Ch) nanoparticles (NPs) containing three different molecules (Biginelli hybrids) were developed and tested for the first time as simple and promising vehicles for anticancer Biginelli-based drugs. The key features of NPs, such as size, surface morphology, drug encapsulation efficiency, and in vitro release were systematically investigated. Rather weak cell selectivity of pure Biginelli hybrids (A–C) to selected cancer cell lines has improved and this has been accompanied with two-to-four times stronger cytotoxic effect of A–C loaded Ch NPs, with a triple reduction in toxicity to healthy cells (MRC-5). It has been observed that the examined NPs induce apoptosis. The cell cycle analysis has confirmed the influence of A-loaded Ch (A-Ch), B-loaded Ch (B-Ch), and C-loaded Ch (C-Ch) on the cell cycle distribution, which was homogenously affected. This is the difference with regard to the effect of A, B, and C on the cell cycle. It has been established that the increased selectivity and antitumor activity of NPs are related to the presence of the carrier.
