AB  - One of the most interesting secondary raw materials within the Kolubara Basin is diatomaceous earth or diatomite, with reserves of 308.670 t in fields B and C. Chemical and mineralogical tests were performed on diatomaceous earth samples. The results of these tests are presented in this paper. Diatomite is a soft sedimentary rock formed by the deposition of cell walls (frustulae) of single-celled algae-diatoms at the bottom of sea and lake basen. Diatom frustules consist of two parts that lie on top of each other and represent a highly porous skeleton of amorphous hydrated silica. Diatom frustule size ranges from 1 μm to 1 mm, usually 10-200 μm.The specific area (SBET (m2/g)) is 47.6. The SEM/EDS, BET and FTIR methods were used for characterization. Based on the presented results, diatomaceous earth can be used in the pharmaceutical, ceramic and food industries.

AB  - In this paper, the effects of the addition of silicon nitride seeds on the phase composition, particle size, and shape of silicon nitride powders obtained by carbothermal reduction-nitridation were studied. Environmentally friendly natural raw material, diatomaceous earth, was used as a Si precursor. Three different carbon sources were used: activated carbon, carbonized sucrose, and carbon cryogel as reducing agents in the molar ratio C/SiO2 = 5. To obtain better-quality Si3N4 powder, the commercial α-Si3N4 powder was added into starting mixtures as seeds in four different quantities. The X-ray diffraction, specific surface area, infrared spectroscopy with Fourier transform, and scanning electron microscopy were employed to characterize the obtained powders. Sucrose as a carbon source enables a major reduction of SiO2 and the onset of β-Si3N4 crystallization at a lower temperature (1350 °C) as well as the complete absence of diatomaceous earth relics. It indicates that the carbothermal reduction-nitridation takes place faster in contrast to the other two carbon sources.

AB  - Nanomaterials based on metal–doped fluorapatite (FAP) have attracted considerable interest as potential next–generation antimicrobial agents. In this study, Cu2+–doped FAP nanocrystals have been successfully synthesized by a neutralization method at room temperature. Their structural, optical, antimicrobial, and hemcompatible properties have been investigated. XRD, FTIR, FESEM, and N2 adsorption–desorption studies indicate the formation of single–phase FAP mesoporous nanopowders, composed of rod–like particles. TEM images confirmed the formation of nanorodes with a length of 60 nm and a width of about 18 nm. Rietveld analysis shows that the Cu2+ ions preferentially substitute Ca2 (6 h) sites in the hexagonal fluorapatite crystal structure. Fluorescence spectroscopy accompanied by MCR–ALS method confirms substitution of Cu2+ ions in FAP crystal lattice with extracting additional d–d band transition at green color from FAP broadband self–activated luminescence in violet–blue color. Antimicrobial studies conducted on Staphylococcus aureus, Escherichia coli and Micrococcus lysodeikticus showed that FAP nanopowder with the highest Cu2+ content have strong bacteriostatic action on Staphylococcus aureus bacterial strain in mediums containing nutrition matters. In addition, this sample in comparison to pure FAP achieved a high percentage of relative reduction of bacterial population for all three species, being >90% in most cases. Fungistatic action is noticed too, throwgh the slowing down mycelium growth of fungus Aspergillus niger, Aspergillus flavus and Penicillium roqueforti and reduction of sporulation of Aspergillus niger species. Cu2+–doped FAP nanocrystals shows a synergistic antimicrobial effect with Cu2+ and F− ions. Concerning the potential biomedical applications, the hemolysis ratios of the Cu2+–doped FAP samples were below 5%. The obtained results pointed out the possible use of the synthesized nanocrystals as broad–spectrum antimicrobial agents for various biomedical and health care preparations.

AB  - Zeolites are a group of natural and synthetic inorganic compounds. They have specific physicochemical properties suitable for industrial application [1,2]. According to their origin, variety of chemical composition, structural characteristics and application, zeolites form a specific group of minerals within the tectosilicates. In sedimentary formations rich in zeolites, the most characteristic minerals that are present are: clinoptilolite/hailandite, chabazite, mordenite, erionite, phillipsite and analcime. The most widespread zeolite of sedimentary origin is represented by the HEU series (clinoptilolite-heylandite). Its general crystal chemical formula is (Na,K,Ca)6Al6Si30O72nH2O.. Based on chemical and X-ray powder diffraction analysis, it is not possible to separate clinoptilolite and hoylandite . This is due to their isostructural nature. To identify these two isostructural minerals, even today, the simplest so-called Mampton's test [3]. Mumpton [4]. The results of X-ray diffraction analysis of thermally treated clinoptilolitic tuffs from the Zlatokop and Beočin deposits will be presented in this paper. The interplane distance values will be shown in the characteristic temperature range from 400oC to 500oC (when the first polymorphic transition occurs). These values characterize the zeolitic tuffs of our deposits in a certain way.

AB  - Zeoliti čine grupu prirodnih i sintetičkih neorganskih jedinjenja, koja imaju specifične fizičkohemijske osobine pogodne za industrijsku primenu. Po svom postanku, raznovrsnosti hemijskog sastava, strukturnim karakteristikama i primeni, zeoliti čine specifičnu grupu alumosilikatnih minerala u okviru klase tektosilikata. Klinoptilolit-hejlanditska serija minerala (HEU-tip zeolitske mreže) zbog svojih fizičkohemijskih osobina predstavlja ekonomski najznačajniju grupu prirodnih zeolita. Brojna su polja primene ovih minerala u ekosistemima: kod odstranjivanja organskog sumpora vezanog za ulja; kod prečišćavanja vazduha od gasova SO2, CO2 i azotnih oksida; koriste se za odstranjivanje cezijuma i stroncijuma iz zemljišta zagađenog nuklearnim otpadom, u oblasti poljoprivrede i veterinarstvu; i dr. Zeolitski tuf slanačke serije je predstavljen sivobelim do žućkasto bojenim agregatom, sa prisutnim limonitskim skramama koje zapunjavaju prsline i pukotine. Mineralni sastav zeolitskog tufa je: KVARC, FELDSPATI, LISKUNI, MINERALI ZEOLITA (iz grupe hejlandit /klinoptilolit), LIMONIT-GETIT, VULKANSKO STAKLO, MINERALI GLINA, CIRKON, APATIT, RUTIL. Osnova uzoraka zeolitskog tufa je kristaloklastična do vitroklastična, delimično šupljikava i porozna.

AB  - This paper presents a comparative analysis of microstructural parameters by the powder X-
ray diffraction method on a polycrystalline sample and the fractal analysis. The presented
results of microstructural parameters are obtained by crystallographic programs FullProf
based on the Rietveld method. The synthetic Ba/Ca-celsian sample has been used for
microstructural parameters analysis. The feldspar sample has been synthesized by the
thermal induction phase transformation process of ion exchange Ca-LTA zeolite with Ba
cation. After the ion exchange Ba/Ca-LTA, the sample was heated at the temperature of
1300°C and the structure of Ba/Ca-feldspar was determined by the X-ray powder diffraction
analysis. The X and U shape parameters that contribute to the strain have been reconstructed
by fractal interpolation. Once we can reconstruct the shapes, which are quantum mechanics
effects, we should provide the data for predicting desired parameters mentioned previously.
We reported in this paper the successful application of this advanced and deep
microstructure analysis, which confirmed original fractal copies based on the presented
morphology characterization.

AB  - Nanotechnology and nanomaterials are beginning to have an impact on the bioforensic science, regarding handling of evidence at crime scenes, its analysis in the laboratory and its presentation in the courtroom. Many different nanomaterials are used for processing of the samples, as DNA, gun powder residues, body fluids etc. Nevertheless, nanopowders, especially luminescent, are the most important for the fingerprinting method. The application of each nanomaterial in the forensic examination depends on its structure and properties, which can successfully be determined by applying fractal nature analysis, as an excellent method for micro and nanomaterials characterization. In our research we successfully synthesized photoluminescent Bi, Y and Ag zeoliteLTA topology nanopowders, which could be used for taking fingerprints from different materials, and therefore, they should be well characterized by fractal analysis. This article aims to highlight some of the major advances in forensic science brought about by nanomaterials fractal characterization, but is not exhaustive of the subject matter.

AB  - Deposits of zeolite tuffs, rich in minerals of the heylandite-clinoptilolite series, in Serbia are
spatially and genetically related to volcanogenic-sedimentary series of sedimentary basins and
were formed as a product of devitrification of volcanic glass. Zeolite minerals in sedimentary
rocks of Neogene age are found in association with volcanic and volcaniclastic rocks. The
lacustrine or marine environment had a great influence on the diagenesis of sediments and the
formation of clinoptilolite at the expense of volcanic glass. In this paper, a preliminary model of
the formation of zeolite deposits in the Tertiary basins of Serbia is presented, through the
processing of all elements of the genetic model.

AB  - Current demand on adsorbent materials is in constant growth, hence scientific society is in ceaseless
research subjecting cheap and optimal adsorbent. Abundant raw materials which may be utilized as
adsorbent of cation species are mica minerals, and vermiculite as one of them is widely examined.
Since wastewater may contain anion or/ and non-ionic pollutants it is needed to functionalize
adsorbent so it may attract those species as well. Goethite and ferrihydrite are potential candidates
for such modification since they: have large specific surface area (SSA), possess hydroxide group
and they are not toxic to the environment. Goethite/ expanded vermiculite (Goe/EV) and ferrihydrite/
expanded vermiculite (Fer/EV) are successfully prepared and those composites have showed better
adsorption related chemical properties than expanded vermiculite (EV) itself. Utilizing BET
methodology, it is determined that Fer/EV possess five-time larger SSA than EV, while Goe/EV is
two times larger. Measuring cation exchange capacity (CEC) it is determined that modified samples
have only ~10% smaller values of CEC. Summary, both composites have shown higher affinity
toward cationic dye, malachite green and also showed their adsorbent potential toward anionic dye,
tartrazine. Thanks to facile preparation of such materials and its cost, it may be concluded that they
are prospective choice as adsorbents, in first order of heavy metals and dyes.

AB  - This paper examines the effects of structural-textural characteristics of sulfide minerals on their leaching from polymetallic concentrates with sulfuric acid and hydrogen peroxide solutions. The polymetallic concentrate was obtained by flotation of polymetallic ore from the Rudnik deposit in Serbia. X-ray diffraction (XRD), qualitative and quantitative mineralogical, scanning electron microscopy (SEM/EDX), and chemical analyses were used to characterize the polymetallic concentrate and leach residue. The polymetallic concentrate contained chalcopyrite, galena, sphalerite, pyrrhotite, and quartz. The total content of sulfide minerals was 69.5%, and the occurrence of free sulfide mineral grains was about 60.9%. The comprehensive thermodynamic analysis was done by HSC Chemistry (R) package 9.9.2.3 to determine optimal experimental leaching conditions. Chalcopyrite, sphalerite, and pyrrhotite oxidized during leaching, and dissolution occurred. The oxidized galena remains in the solid residual as insoluble anglesite. Also, elemental sulfur and unleached minerals of copper, zinc, and iron were found in the leach residues. It was found that the structural assembly of sulfide minerals in the leach residue is very favorable and that undissolved sulfide grains are primarily present in free form. Accordingly, there was no reason to reduce the leaching rate with time. The presence of elemental sulfur and anglesite formed in the leaching process and precipitated on the surface of mineral grains was confirmed by XRD, quantitative and qualitative mineralogical analysis, and SEM/EDX.

AB  - Zeolites are a group of natural and artificial inorganic compounds, which have specific physicochemical properties appropriate for industrial application. These minerals make a specific group of alumosilicates within tectosilicates because of their origin, chemical compositions, structural characteristics and application. This paper presents the results of mineralogical and crystallographic examination of zeolite tuff samples from the Toponica deposit. The deposit of zeolite tuff ""Toponica"" is located in the extreme eastern part of Kosmet near Kosovska Kamenica. The immediate geological structure of the zeolite tuff deposit consists of the Lower Miocene (M) clayey sandstone, the horizon of the white zeolite tuff and the reclassified Miocene clays, clays and gravel. The basic mineral composition is the mineral clinoptilolite-Ca from the heylandite series.

AB  - Forensic photography, also referred to as crime scene photography, is an activity that records the initial appearance of the crime scene and physical evidence in order to provide a permanent record for the court. Nowadays, we cannot imagine a crime scene investigation without photographic evidence. Crime or accident scene photographs can often be reanalyzed in cold cases or when the images need to be enlarged to show critical details. Fractals are rough or fragmented geometric shapes that can be subdivided into parts, each of which is a reduced copy of the whole. Fractal dimension (FD) is an important fractal geometry feature. There are many applications of fractals in various forensic fields, including image processing, image analysis, texture segmentation, shape classification, and identifying the image features such as roughness and smoothness of an image. Fractal analysis is applicable in forensic archeology and paleontology, as well. The damaged image can be reviewed, analyzed, and reconstructed by fractal nature analysis.

topology are presented in this paper. Thermally induced phase transformation of Mn-
exchange zeolites are followed in the range from 700 to 1300 o C. Both frameworks collapse
into amorphous intermediate products after heating between 600 and 650 o C. Prolonged
heating of the intermediate product above 1100 °C results directly in formation of a disorder
Mn-anorthiteLTA and Mn-anorthiteFAU. The parameter of unit cell of Mn-anorthiteLTA and Mn-

AB  - Coupled substitution of fluorapatite (FAP) crystal lattice plays an important role in the engineering of optically active nanomaterials. Uniform fluorapatite nanopowders doped with praseodymium (Pr3+) and carbonate (CO32-) ions have been successfully synthesized by precipitation method under room temperature (25 degrees C). The structural, morphological, chemical and optical properties of monophase material were characterized by X-ray diffraction (XRD), Fourier Transform Infrared and Far Infrared Spectroscopy (FTIR and FIR, respectively), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM/EDS), Transmission Electron Microscopy (TEM) and Photoluminescence Spectroscopy (PL). Coupled substitution of FAP crystal lattice with Pr3+ and CO32- reduces the crystallite size with a constant c/a ratio of 1.72. FTIR study showed that synthesized nanopowders were AB-type CO32- substitution, and FIR study revealed new Pr-O vibrations. TEM analysis was found that synthesized nanopowders were composed of irregular spheres in the nanometer range. The fluorescence of FAP nanoparticles was in the violet-blue region of the visible part of the spectrum. When Pr3+ was doped in a lattice, the violet-blue emission becomes sharper due to reabsorption. MCR-ALS analyses of fluorescence spectra indicated the shift of the maximum to the blue color with the increase in the concentration of Pr3+ ions. Additionally, luminescent nanopowders demonstrated significant antibacterial activity against Escherichia coli. As the obtained nanoparticles showed a good absorption of ultraviolet A light and reabsorption of blue-green luminescence, they are suitable for further development of optically active nanomaterials for light filtering. Optically active PrCFAP nanopowders with antibacterial properties may be promising additives for the development of multifunctional cosmetic and health care products.

AB  - The current problem is the issue of safe storage of nuclear waste, especially materials generated as waste in nuclear power plants. In the nuclear fuel cycle, in the fuel, a large amount of artificial radionuclides are created (most of them are much more active than uranium), so radioactivity in the normal reactor operation is about a billion times greater than before entering the reactor (1021 Bq observed for 100 tons). Radionuclides are the most important part of the nuclear waste and their safe storage and removal from the natural environment is very important. For now, utilized nuclear fuel (high radio-co-active waste which remains after its transformation) is temporarily stored in special storages in order to exploit a rapid decline initial period of its radioactivity and thus simplify further operation with it. In this paper the literature data of different methods of disposal of nuclear waste are presented.

abstract = "Forensic photography, also referred to as crime scene photography, is an activity that records the initial appearance of the crime scene and physical evidence in order to provide a permanent record for the court. Nowadays, we cannot imagine a crime scene investigation without photographic evidence. Crime or accident scene photographs can often be reanalyzed in cold cases or when the images need to be enlarged to show critical details. Fractals are rough or fragmented geometric shapes that can be subdivided into parts, each of which is a reduced copy of the whole. Fractal dimension (FD) is an important fractal geometry feature. There are many applications of fractals in various forensic fields, including image processing, image analysis, texture segmentation, shape classification, and identifying the image features such as roughness and smoothness of an image.

AB  - The Cerovo-Cementacija 2 porphyry Cu deposit, hosted by hydrothermally altered hornblende andesite,
located into the Bor Metallogenic Zone, eastern Serbia, has been investigated. In this porphyry Cu
deposit, the following mineral parageneses have been established: i) pyrite-chalcopyrite with Mo; ii)
quartz-pyrite with Au; iii) digenite-chalcocite-covellite with Au; iv) chalcedony by sulfatization and
sulphation; v) malachite-azurite-limonite. Chalcopyrite is the major Cu mineral and it is the most
abundant compared to other established Cu-sulfide minerals. By the ascending and descending
hydrothermal processes along the Zone-1 (cementation zone), chalcopyrite was commonly transformed
into secondary Cu sulfide minerals (digenite, chalcocite, anilite, covellite, etc.), while those appearances
is less represented to the Zone-2 (transitional zone).

AB  - Since about 50 years it is known that giant deposits of natural zeolites of pyroclastic origin are spread over all Miocene sediments of Serbia. Such rocks have often zeolite contents between 60 and 90%. The most significant Serbian deposits of natural zeolites are: Zlatokop, Igros, Beocin, Toponica, and Slanci. Based on obtained results of structural, chemical, physical, and thermal analyses, the investigated zeolite tuffs can be generally defined in two mineral series: clinoptilolite-Ca, and heulandite-Ca. The interest for these materials is in steady mass growth as they are of vital importance for Serbian economy. The oversights of perennial mineralogical research of Serbian giant deposits of natural zeolites were presented in this paper.

AB  - Octadecyldimethylbenzyl ammonium chloride (OA) was used as a surfactant for the preparation of organokaolin. The natural kaolin (from a plant for production of quartz sand in Rgotina, Serbia) was modified with a surfactant in amount equal to 90% of the kaolin cation exchange capacity (CEC). FTIR spectroscopy was used for characterization of the new product. FTIR spectra confirmed the presence of OA ions at the kaolin surface. Adsorption of mycotoxins - zearalenone (ZEN) and ochratoxin A (OCHRA) was studied by organokaolin at different amounts of adsorbent and pHs. Results showed that the presence of organic cations in the kaolin structure increased adsorption of both ZEN and OCHRA. Adsorption of the mycotoxins by organokaolin increased with increasing amounts of adsorbent and, at the lowest amount of solids in suspension, adsorption of ZEN and OCHRA was slightly higher at pH 7 and 9.

AB  - Srebrom dopirani fluorapatiti (AgFAP) su sintetisani postupkom neutralizacije 
(reakcija Ag2O rastvarenog u HF i H3PO4 sa suspenzijom Ca(OH)2). [1] Sintetisani 
uzorci AgFAP imali su procentnu zastupljenost jona srebra ([Ag/(Ag + Ca)]·100%) od 
0.001, 0.01 i 1%. Rendgenska difraktometrijska (XRD) analiza uzoraka FAP i AgFAP 
pokazala je da su položaji difrakcionih pikova slični i da su u skladu sa ASTM podacima za fluorapatite (Slika 1). FAP kao materijal ima kristalnu rešetku sa heksagonalnom P63/m prostornom grupom, sa dva strukturno različita položaja Ca2+ jona (Ca1 (4f) i Ca2 (6h) položaji). FTIR and SEM analize pokazale su da su čestice AgFAP uzoraka homogene i nano-veličine. Fluorescencija AgFAP uzoraka je pomerena ka zelenom regionu, u odnosu na fluorescenciju FAP nanočestica (u ljubičastom regionu vidljivog dela spektra). MCR ALS analize su pokazale formiranje dva maksimuma u AgFAP fluorescentnom spektru (na 420 i 520 nm), kao posledica dopiranja Ag+ jona u Ca1 (4f) položaj FAP rešetke (Slika 1). Rezultati DFT proračuna su pokazali da je Ag+ jon jače vezan u Ca1 položaju (-1352,6 kcal/mol) nego u Ca2 položaju (-1249.0 kcal/mol). Ispitivanja antibakterijskih aktivnosti su pokazale da svi uzorci AgFAP imaju biocidni efekat na patogene, [1] dok samo AgFAP3 uzorak (1% Ag+) može poslužiti kao nanomaterijala za zaštitu od zračenja, kao i za pripremu fotoluminiscentnih dozimetara, jer ovaj materijal apsorbuje fotone u celoj oblasti UV zračenja. Rezultati ove studije ukazuju da su srebrom dopirani fluorapatitni 
nanomaterijali pogodni za različite biomedicinske primene, kao antibakterijski 
biomaterijali u ortopediji, stomatologiji i u prečišćavanje otpadnih voda.
AB  - Silver doped fluorapatite (AgFAP) nanopowders were synthesised by 
neutralization method (reaction of dissolving Ag2O in solution of HF and H3PO4 with suspension of Ca(OH)2). [1] AgFAP samples were synthesized with atomic ratios of [Ag/(Ag + Ca)]·100% of 0.001, 0.01 and 1%. The XRD patterns of FAP and Ag+-doped FAP samples (Figure 1) are similar, with the positions of X-ray diffraction peaks in accordance with ASTM data for fluorapatite. FAP as material has a crystal lattice with a hexagonal symmetry space group P63/m, with two structurally different positions of Ca2+ ion (Ca1 (4f) and Ca2 (6h) sites). FTIR and SEM analysis showed that the particles of AgFAP samples are nano-sized and homogenous. Fluorescence of AgFAP is red shifted to the green region compared to fluorescence of FAP nanoparticles (in the violet region of visible part of the spectrum). MCR-ALS analyses showed the formation of two maxima in AgFAP fluorescence spectra (at 420 and 520 nm), as a consequence of Ag+ ions doping at Ca1 (4f) site in the FAP lattice (Figure 1). The results of DFT calculations showed that an Ag+ ion is stronger bonded to Ca1 site (-1352.6 kcal/mol) than to Ca2 site (-1249.0 kcal/mol). Antibacterial studies have shown that all studied AgFAP samples exhibit biocidal effect against pathogens, [1] while only AgFAP3 (1% of Ag+) nanopowder might be used as the radiation protective nanomaterial, as well as for preparation of photoluminescence dosimeters, because this material absorbs photons over all part of the UV radiation spectrum. The result of this study indicates that Ag-doped fluorapatite nanomaterials are promising for different biomedical applications, as antibacterial biomaterials in orthopedics, dentistry and in the purification of waste water.
