AB  - This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a vibration mill over the following times: 10, 20 and 30 min. Depending on the time required for the mechanical activation, the change in the filler grain size and shape was analysed along their effects on the talc-filled lost foam coating dispersion ability and stability. In order to characterize the filler, the following methods were used: X-ray diffraction, scanning electron microscopy and optic microscopy. The coating composition was tuned by choosing the suitable grain size and shape factor of the activated filler. In addition, different coating components (additives, solvent) were applied to alter the coating generation procedure. It was shown that the application of this type of the lost foam refractory coatings - water-based coatings - have a positive influence on quality of the aluminium alloy castings, which contributes to reducing the cost of cleaning and processing of the castings. Also, alcohol-based refractory coatings with talc-based activated fillers were tested and used to have the castings produced in the sand moulds.
AB  - Истраживање је фокусирано на поступке припреме пуниоца на бази талка у циљу побољшања реолошких својстава “lost foam” ватросталних премаза. Талк величине зрна од 40 m механички је активиран у вибрационом млину у временима од 10, 20 и 30 min.  У зависности од времена механичке активације, анализирана је промена величине и облика зрна пуниоца заједно са њиховим утицајем на дисперзност и стабилност суспензије премаза. За карактеризацију пуниоца коришћене су следеће методе: рендгенска дифракциона анализа, скенинг електронска и оптичка микорскопија. Испитиван је утицај састава премаза избором подесне величине и облика зрна активираног пуниоца на квалитет премаза. Осим тога, примењене су различите компоненте премаза и измењен је поступак израде премаза. Показано је да је примена ове врсте “lost foam” ватросталних премаза на воденој основи имала позитиван утицај на квалитет одливака од легура алуминијума. Такође, тестирани су ватростални премази на бази алкохола са активираним пуниоцем на бази талка који су коришћени за ливење одливака у калупе од песка.

AB  - Supstituisani estri 1,4-dihidropiridina (1,4-DHP) nastaju u reakciji etil-acetoacetata i odgovarajućih supstituisanih aldehida u prisustvu amonijaka. Nastali estri sa primarnim aminima formiraju amide. Serija amida nastalih od navednih jedinjenja je sintetisana sa namerom da se ispitaju njihove karakteristike i antioksidativna aktivnost. U ovde prikazanom istraživanju za aminolizu upotrebljen je 2-aminotiazol. Antioksidativna aktivnost je ispitivana DPPH (2,2-difenil-1-pikrilhidrazil-radikal) i ABTS (2,2'-azino-bis(3-etilbenzotiazolin-6-sulfonska kiselina)) metodama, a pored toga određene su tačke topljenje, snimljeni IR spektri i izvršena je elementalna analiza.
AB  - The substituted esters of 1,4-dihydropyirdines (1,4-DHP) are formed in the reaction of ethyl acetoacetate and corresponding substituted aldehydes in the presence of ammonia. Amides form from esters of substituted 1,4-DHP by aminolysis employing primary amines. A series of amides of the mentioned compounds was synthesized with the aim to analyze their chemical properties and antioxidative activity. The amine used in the present research was 2-aminothiazole. The antioxidative activity was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl radical) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) methods; melting points and IR were measured and elemental analysis was performed.

AB  - The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these precursor materials and modified with goethite nano-deposit, alpha-FeOOH, A1/ and A2/MWCNT-alpha-FeO(OH) adsorbents used for As(V) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on adsorption efficiency were studied. Adsorption data modelling by the Langmuir isotherm, revealed good adsorption capacities (in mg g(-1)) of 18.8 for As(V) and 60.1 and 44.2 for Pb2+ and Cd2+ on A2/MWCNT, respectively. Also, 27.6 and 29.8 mg g(-1) of As(V) on A1/ and A2/MWCNT-alpha-FeO(OH), respectively, were removed. Thermodynamic parameters showed that the adsorption is spontaneous and endothermic processes. Results of the study of influences of competitive ions: bicarbonate, sulfate, phosphate, silicate, chromate, fluoride and natural organic matter (NOM), i.e., humic acid (HA), showed the highest effect of phosphate on the decrease of arsenate adsorption. Time-dependent adsorption was best described by pseudo-second-order kinetic model and Weber-Morris model which predicted intra-particle diffusion as a rate-controlling step. Also, activation energy (E-a/kJ mol(-1)): 8.85 for Cd2+, 9.25 for Pb2+ and 7.98 for As(V), were obtained from kinetic data.

AB  - Fourteen mono- and bis-carbohydrazone ligands have been synthesized and characterized. Antioxidant activity of the substances was investigated together with possible (E)/(Z) isomerization, and explained on the most active antioxidant compound 4 in various dimethyl sulphoxide-water mixtures. The addition of water to the system was involved in the formation of hydrated molecules which was confirmed in NMR after the addition of D2O. The ligands were tested in vitro against Gram-positive and Gram-negative bacteria and fungi, and their activity was discussed in relation to the structure of investigated carbohydrazone.

AB  - The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen solvents in the wavelength range from 200 to 400 nm. The position of the absorption maxima (λmax) of the examined acids showed that the ultraviolet absorption maximum wavelengths of picolinic acid N-oxide are the shortest, and those of isonicotinic acid N-oxide acid are the longest. In order to analyze the solvent effect on the obtained absorption spectra, the ultraviolet absorption frequen­cies of the electronic transitions in the carboxylic group of the examined acids were correlated using a total solvatochromic equation of the form Vmax = V0 + + Sπ*+ aα+ bβ, where Vmax is the absorption frequency (1/λmax), π*is a measure of the solvent polarity, β represents the scale of solvent hydrogen bond acceptor basicities and α represents the scale of solvent hydrogen bond donor acidities. The correlation of the spectroscopic data was carried out by means of multiple linear regression analysis. The solvent effects on the ultra­violet absorption maximums of the examined acids were discussed.
AB  - UV apsorpcioni spektri pikolinske kiseline N-oksida, nikotinske kiseline N-oksida i izonikotinske kiseline N-oksida određeni su u 14 protičnih i aprotičnih rastvarača u opsegu od 200-400 nm. Položaji maksimuma apsorpcije bili su najniži za pikolinsku kiseline N-oksid, a najviši za izonikotinsku kiseline N-oksid. Da bi se analizirao uticaj ratvarača, apsorpcione frekvence su korelisane Kamlet-Taftovom jednačinom, kojom se uticaj polarnosti/polarizabilnosti, proton-donorskog i proton-akceptorskog dejstva rastvarača može kvantitativno izraziti.

AB  - In this paper, results of the investigation of the polymer materials for evaporate patterns and their application in the new casting method (EPC process) are presented. The basic characteristic of EPC process is that patterns and gating of moulds, made of polymers, stay in the cast till the liquid metal inflow. In contact with liquid metal, intensely, in relatively short time, polymer pattern is been decomposing and evaporating , accompanied by castings crystallization. In order to achieve qualitative and profitable castings production by the EPC process it is necessary to reach the balance in the system: evaporable polymer pattern-liquid metal-refractory coat-sandy cast in the phase of metal inflow, decomposition and evaporation of polymer pattern, formation and soldification of castings. Results of this investigation of this process relate on application of puffed polystyrene of various densities (kg/m3): 18, 20, 25. Application of lower density polymer (20 kg/m3) gave positive results on structure and properties of silumina castings obtained using this casting method.

AB  - Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods of photolytic, photocatalytic and microbiological degradation of methyl tertiary butyl ether (MTBE) dissolved in wastewaters. The effects of concentrated solar radiation simulated with sodium lamp (SONT UV 400) have been investigated in laboratory experiments. Our result indicated that bacteria Pseudomonas strain CY, isolated from the kerosene, and added alone, was able to gradually degrade MTBE and to decrease its concentration for 93.6% in 12 h. However, the percentage of photolytic degradation decrease in only 4 h was 99.2%. By adding Pseudomonas strain CY after 4 h of light treatment, the degradation was enhanced to 99.55% in additional 5 h. The photocatalytic process was performed in slurry-catalyst reactor with different concentrations of TiO2 catalyst: 5, 0.5 and 0.25 g/L. The MTBE degradation producing carbon dioxide reached 91% in only 150 min, when 5 g/L of catalyst was used.
