AB  - Microstructure assessment is crucial for the design and production of high-quality alloys such as cast aluminum alloy ingots. Along with the effect of a more homogeneous microstructure to result in much better mechanical properties, better as-cast alloy quality indicates a higher efficiency of the aluminum alloys production process. During the aluminum alloy solidification process many microstructural defects can occur, which deteriorate the mechanical properties and hence decrease the usability of such an ingot. Application of the electromagnetic field during the vertical continuous casting process significantly reduces occurrence of these defects. In the present study, EN AW 7075 alloy samples were cast with and without application of an electromagnetic field and examined regarding the microstructure, electrical conductivity, and changes in the phase composition. The obtained results clearly show that it is possible to decrease or avoid casting defects by the electromagnetic field application as verified by the microstructure characterization and quantification, electrical conductivity tests and differential thermal analysis (DTA).
AB  - Određivanje i analiza mikrostrukture su presudni tokom dizajniranja i prilikom dobijanja legura aluminijuma visokog kvaliteta u livenom stanju. Pored neizbežne povezanosti homogenije mikrostrukture i boljih mehaničkih svojstava, bolji kvalitet u livenom stanju ukazuje i na veću efikasnost procesa proizvodnje legura aluminijuma. Tokom procesa očvršćavanja legure aluminijuma mogu se pojaviti mnogi mikro-strukturni nedostaci koji pogoršavaju mehanička svojstva, a samim tim i upotrebljivost takvog odlivka. Delovanje elektromagnetnog polja tokom procesa vertikalnog kontinualnog livenja značajno smanjuje pojavu ovih grešaka. Ovde prikazani rezultati dobijeni ispitivanjem mikrostrukture, električne provodljivosti i promene faznog sastava uzoraka legure EN AV 7075, odlivene u prisustvu elektromagnetnog polja, kao i bez njega, jasno pokazuju da je moguće smanjiti ili izbeći nedostatke livenja pri-menom elektromagnetnog polja. To je pokazano pomoću određivanja i analize mikro-strukture, ispitivanja električne provodljivosti i diferencijalne termičke analize (DTA).

AB  - The study is focused on the determination of the most effective chemical leaching process for the simultaneous demineralization/deashing and desulfuri­zation of subbituminous coal from the Bogovina Basin. Coal was treated for 30 min, at different temperatures, using variable concentrations of hydro­chloric, nitric, acetic and citric acids; hydrogen peroxide, mixture of hyd­rogen peroxide and nitric acid (pH 2), as well as by the stepwise leaching pro­cess (nitric acid + mixture of hydrogen peroxide and nitric acid, pH 2). The changes in mineral composition, caused by the chemical leaching, are followed using X-ray diffraction, whereas alterations of coal organic matter are tracked by Fourier-transform infrared spectroscopy and the content of fixed carbon. Inorganic acid leaching, regardless of the temperature and acid concentration, enabled the successful deashing of coal, whereas the percent of desulfurization was insufficient. The organic acid leaching was not satisfactory for both, deashing and desulfurization. Leaching by H2O2 and H2O2/HNO3 mixture (pH 2) resulted in moderate desulfurization, but the ash reduction was low. The most suitable method for the simultaneous effective ash (78 wt.%) and the sulfur (66 wt. %) removal from Bogovina coal is the two-step leaching, com­bining 10 vol. % HNO3 and mixture of 35 vol. % H2O2/10 vol. % HNO3 of pH 2 at 60 °C.
AB  - Циљ рада је одређивање најефикаснијег хемијског третмана за истовремену деминерализацију/отпепељавање и одсумпоравање мрког угља из басена Боговина. Угаљ је
третиран 30 min, на различитим температурама, користећи различите концентрације
хлороводоничне, азотне, сирћетне и лимунске киселине; водоник-пероксид, смешу
водоник-пероксида и азотне киселине (pH 2), као и двостепено испирање (азотна киселина + смеша водоник-пероксида и азотне киселине, pH 2). Промене у минералном саставу, проузроковане хемијским третманом, праћене су дифракцијом рендгентских зрака, док су промене органске супстанце угља праћене помоћу инфрацрвене спектроскопије са Фуријеовом трансформацијом и садржаја фиксног угљеника. Третман неорганским киселинама, независно од температуре и концентрације реагенса, омогућио је успешно отпепељавање угља, док је проценат одсумпоравања био недовољан. Третман органским киселинама није био задовољавајући, ни за отпепељавање, ни за одсумпоравање. Третман угља са Н2О2 и смешом Н2О2/HNO3 (pH 2) резултовао је умереним одсумпоравањем, али је смањење садржаја пепела било мало. Најприкладнија метода за истовремено ефикасно уклањање пепела (78 мас. %) и сумпора (66 мас. %) из боговинског угља је двостепено испирање, комбинацијом 10 запр. % HNO3 и смеше 35 запр. % H2O2/10 запр. % HNO3 (pH 2) на 60 °С.

AB  - Adsorbents based on magnetic materials are the subject of numerous researches. Beside good magnetism and functional surface, manganese ferrite is unstable and prone to form low mechanical strength agglomerates, which necessitate its deposition on the substrate surface. Expanded vermiculite outer surfac, is a useful medium for the deposition of nanoparticles whereas intercation layer is suitable for holding cation species (distance of 2:1 layers may be greater than 10 Å). Due to its relatively high surface area, cation exchange capacity and natural abundance of vermiculite, this mica mineral and its composites could be valorized as potentially low-cost adsorbents. In this study, manganese ferrite/expanded vermiculite (MnFe2O4/EV) composite was prepared by in-situ method. Deposited manganese ferrite particles on the surface of EV were formed in the solvothermal reaction using suitable reagents. Both composite and base material are characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) specific surface area (SSA), cation exchange capacity (CEC) and pH point of zero charge (pHPZC) determination. The adsorption properties of MnFe2O4/EV and EV have been investigated in a batch system at pH close to the pHPZC for the removal of Ni (II) from water. Considering process parameters such as contact time, adsorbent dosage and temperature: adsorption type, isotherm parameters (Langmuir and Freundlich) and rate of adsorption parameters were determined. Results of the kinetic studies gave fine correlations with pseudo – second order and Weber – Morris model. Taking into consideration fact that EV had low CEC values and SSA, obtained composite have high adsorption capacity (more than 30 mg Ni g-1). Also, X-ray diffractograms showed alteration of biotite vermiculite (formed during solvothermal action) into phlogopite (formed after adsorption process and aging). The methodology applied in this work may be utilized for the fabrication of other ferrite spinels, perovskites and other oxide systems.
AB  - Adsorbenti na bazi magnetičnih materijala su predmet brojnih istraživanja. Osim dobre magnetičnosti i funkcioncionalnoj površini, mangan ferit je nestabilan i teši formiranju aglomerata niske mehaničke čvrstine, čime se iziskuje njegova depozicija na površini supstrata. Spoljna površina ekspandovanog vermikulita je korisni medijum za depoziciju nanočestica dok interkalacioni sloj je podesan za zadržavanje katjonskih vrsta (rastojanje između slojeva može biti iznad 10 Å). Zahvaljujući relativno visokoj površini, kapacitetu katjonske izmene i prirodnoj zastupljenosti vermikulita, ovaj mineral liskuna i njegovi kompoziti mogu biti valorizovani kao potencijalni povoljni adsorbenti. U ovoj studiji, kompozit mangan ferita/eksapndovanom vermikulitu (MnFe2O4/EV) pripremljen je in-situ metodom. Deponovane čestice mangan ferita na površini EV formirane su u solvotermalnoj reakciji korišćenjem podesnih reagenasa. Kompozit kao i bazni materijal karakterizovani su: infracrvenom spektroskopijom sa Furijeovom transformacijom (FTIR), difrakcijom X-zraka na prahu (XRPD), skenirajućom elektronskom mikroskopijom (SEM), specifičnom površinom (SSA) određenom metodologijom po BET-u, kapacitetom katjonske izmene (CEC) i pH tačke nultog naelektrisanja (pHPZC). Adsorpciona svojstva MnFe2O4/EV i EV istražena su u šaržnom sistemu na pH vrednosti bliskoj pH tački nultog naelektrisanja za uklanjane Ni (II) iz vode. Uzimajući u obzir procesne parametre kao što su vreme kontakta, masa adsorbenta i temperatura određeni su: tip adsorpcije, izotermski parametri (Lengmir i Frojndlih) kao i parametri brzine adsorpcije. Rezultati kinetičkih studija dobro se korelišu pseudo – drugom redu reakcije i Veber – Morisovim modelom. Uzevši u obzir činjenicu da je uzorak EV imao malu vrednost CEC i nisku specifičnu površinu, dobijeni kompozit ima visok adsorpcioni kapacitet (preko 30 mg Ni g-1). Osim toga, difraktogrami X-zraka pokazali su alteraciju biotitskog vermikulita (formiranog solvotermalnom akcijom) u flogopit (formiran nakon adsorpcionog procesa i starenjem). Metodologija primenjena u ovom radu može biti iskorištena za proizvodnju drugih feritnih spinela, perovskita i ostalih oksidnih sistema.

AB  - Environmental pollution is a serious problem that affects air, water and soil. Emission of CO2 into the atmosphere is considered to be a major cause of the greenhouse effect and global warming. The present invention relates to the application of mechanochemically activated sodium carbonate to the environment, owing to the significant increase in the absorption and chemisorption properties of sodium carbonate due to activation. Using activated sodium carbonate, it was shown that the mass of the starting sample increase up to 30% at room conditions and temperature over time. Sodium carbonate activated in mechanochemical activator, has significantly increased absorption properties, and also can be applied to existing appliances that otherwise use sodium carbonate for the purpose of CO2 absorption, for environmental protection, which would also increase their effectiveness.

AB  - Natural bentonite clay from the Bogovina locality in Serbia was Na-exchanged and modified using hexadecyll-trimethylammonium bromide as surfactant and organobentonite was obtained. The influence of modifications on the structural, textural and sorption properties of bentonite was investigated. It was estimated that modifications solely replace exchangeable cations in smectite layers, whereas other admixture minerals (quartz, calcite, feldspar) in bentonite remain unaffected. According to X-ray results the modification lead to changes in the smectite structure by either decreasing, for Na-bentonite, or increasing, for organobentonite, the interplanar spacing, JQOI- The appearance of three new bands in IR spectra of HDTMA-bentonite comparing to those of raw and Na-bentonite assigned to the methylene vibrations confirmed the embedding of aliphatic cations into smectite structure. In organobentonite a significant change in textural properties was observed. In particular, specific surface area dramatically decreased while originally meso and microporous material became almost completely non-porous. Despite almost insignificant specific surface area the synthesized organobentonite due to gained organophyllity of its surface exhibits exquisite adsorption properties toward investigated textile dyes having adsorption capacity approx. 2 times higher than activated carbon.
AB  - Prirodna bentonitna glina sa lokaliteta Bogovina u Srbiji je natrijumski izmenjena i modifikovana heksadeciltrimetil amonijum-bromidom kao surfaktantom, pri čemu je dobijen organobentonit. Ispitivan je uticaj modifikacije na strukturu, teksturalna i adsorpciona svojstva bentonita. Utvrđeno je da primenjeni postupci modifikacije dovode isključivo do izmene katjona u medulamelamom sloju smektita, dok modifikacija ne deluje na druge prateće minerale u bentonitu (kvare, kalcit, feldspat). Uprkos neznatnoj specifičnoj površini sintetizovani organobentonit zahvaljujući novodobijenoj organofilnosti površine pokazuje izuzetna adsorpciona svojstva prema tekstilnim bojama, imajući adsorpcioni kapacitet oko 2 puta veći od aktivnog uglja.

AB  - Hydrogenation of the animal fats and edible oils is a very important operation in the fats and oils industry. A catalyst usually used in industrial processes of the tallow and fat hydrogenation and in the vegetable oils selective hydrogenation, is a nickel catalyst deposited on a silicate support. Choice and activation of the support are of the vital importance for obtaining a highly active hydrogenation catalyst. As a support suitable for the catalyst's synthesis, we have chosen the natural biogenic sediment rock - diatomite earth. By an appropriate chemical and thermal treatment of the domestic crude diatomite, we have obtained a type of the activated support with performances, in comparison with the same-class commercial supports, quite satisfying the requirements.

AB  - Triglycerides are characterized by complex melting behaviour, as reflected by multiple melting temperatures. They can solidify in different crystal structures and this polymorphism can be defined as the ability to reveal different unit cell structures in crystals, originating from a variety of molecular conformations and molecular packing. A detailed study of the morphology of the polymorphic forms of edible vegetable oils using X-ray diffraction and polarized light microscopy is presented. An important problem in the study is the correlation between the melting/solidification behaviour and the crystal structure. The application of X-ray diffraction method allows to perform dynamic studies of structural changes during fast or slow thermal transition processes.
AB  - Karakterizacija triglicerida se ogleda u kompleksnosti osobine topljenja što se u krajnosti reflektuje na postojanje više temperatura topljenja. Trigliceridi kristališu u raznim kristalnim formama i takav polimorfizam se može definisati kao sposobnost otkrivanja različitih jediničnih strukturalnih ćelija u kristalima, što potiče od različitosti rasporeda i pakovanja molekula. U ovom radu je prikazano ispitivanje morfologije polimorfnih oblika jestivih biljnih masnoća metodom rendgenske difrakcije i polarizacionim mikroskopom. Važnost ovog rada je ukazivanje na korelaciju osobina: topljenje (ili hlađenje) masnoće i njena kristalna struktura.

AB  - The behavior of Kosovo Basin (Yugoslavia) soft brown coal was studied during a direct liquefaction process by catalytic hydrogenation. A stream of hydrogen was passed through a tetralin dispersion of the pulverized coal in the presence of commercial extruded hydrogenating-desulphurizing cobalt-moly­bdenum/alumina catalyst. The experiments were carried out in the temperature range between 365 and 440°C at 13.5 and 15.0 MPa, the reactants being kept at selected stationary working conditions for 1-8 hrs. The yields of liquid products soluble in n-heptane (light oils), asphaltenes (n-heptane insoluble liquid products) and the solid coal residue served as a basis for the estimation of coal reactivity and for the calculation of total coal conversion. The liquid product yields varied substantially depending on the reaction temperature and the residence time. The total conversion under most of the applied reaction conditions was found to be around 80%, the highest (~86%) being observed with the longest, 8 h residence time. Various types of grains of modified coal and newly formed types of coal grains, as well as mineral matter were identified by micropetrographic analysis, indicating the release of gases in the initial stages of hydrogenation and the formation of semi-coke and coke by the polymerization of liquid products in the later reaction stages.
AB  - Ispitivano je ponašanje mekog mrkog uglja Kosovskog basena (Jugoslavija) pri direktnoj likvefakciji.

Eksperimenti su izvođeni na temperaturi 365 i 440°C, pritisku 13,5 i 15,0 MPa, u trajanju 1-8 sati. Reaktivnost uglja je procenjivana i ukupna totalna konverzija izračunavana je na osnovu prinosa tečnih proizvoda rastvornih u n-heptanu (laka ulja), asfaltena (proizvodi nerastvorni u n-heptanu) i čvrstog ostatka. Konverzija uglja pri navedenim uslovima iznosila je oko 80 %, a najveća je bila (~86 %) pri najdužem reakcionom vremenu. Mikropetrografskom analizom identifikovane su različite vrste zrna modifikovanog uglja kao i novo stvoreni tipovi zrna uglja kao i mineralnog materijala. Dobijeni rezultati ukazuju da se gasovi oslobađaju u početnim fazama hidrogenizacije, a da polimerizacijom tečnih proizvoda polu-koks i koks postaju u kasnijim fazama hidrogenizacije.
