AB  - In this paper we present the phase and morphological characteristics of urinary stones from Serbian patients. The study included for the first time the determination of the phase composition and a statistical analysis of the presence of different types of urinary stones in both men and women in Serbia. The main goal of study was representation of collected data for the first time. For past three years, more than 600 samples were collected from Serbian patients. The phase composition of all samples of urinary stones was investigated using XRD analysis. Morphology and chemical composition of phases in some characteristic samples was determinate by the SEM-EDS analysis. Results indicate that there are several different types of urinary stones that vary in mineral composition, chemistry and morphology. It was found that 312 (52%) of the 600 stones were composed of calcium oxalate minerals (CaOx): 17.3% of which were pure calcium oxalate monohydrate COM, 4% were pure calcium oxalate dihydrate COD; 200 (33.3%) were a mixture of CaOx and Hydroxyapatite HA, 19 (3.1%) were uric acid (uricite) UA and uric acid dihydrate UAD, 17 (2.8%) were a combination of UA and CaOx minerals, 41 (6.8%) were combination of CaP minerals and CaOx, 11 (1.9%) were cystine (Cy) stones. The obtained data shows the diversity of types of urinary stones. Morphological, chemical and XRPD analysis give us statistical data which shows that the most common urinary stones from Serbian patients are from CaOx group and in most of cases are associated with CaP. © 2019 Elsevier B.V.

AB  - Modified solution precipitation method was used to prepare pure and doped Mg, Sr and Na hydroxyapatite type materials (CaP, CaMgP and CaSrNaP). Modification consisted of partial substitution of nitrates by acetate solution in order to achieve a more soluble and cost effective synthesis. The obtained samples were calcined at 400 degrees C (CaP400, CaMgP400 and CaSrNaP400). All powders were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Calcined samples were densified at 1000 degrees C in an air for 3 h (CaP1000, CaMgP1000 and CaSrNaP1000). Sintered samples were characterized by XRPD, FTIR, SEM, EDS and complex impedance methods. The highest conductivity was found for the multi-doped phosphate sample (CaSrNaP1000) at 700 degrees C (1.90x10(-3)Omega(-1)cm(-1)). The corresponding activation energies of conductivity amounted to 0.31 eV in the temperature range 500-700 degrees C.
AB  - Метода таложне титрације коришћена је за добијање чистог и допираног хидроксиапатита јонима Sr, Mg и Na (CaP, CaMgP and CaSrNaP). За синтезу супституисаних хидроксиапатитских материјала коришћена је модификована таложна метода у односу на досада познате методе. Због боље растворљивости и знатно веће исплативости коришћени су раствори ацетата уместо нитрата. Синтетисани материјали су калцинисани на 400 °C, а затим окарактерисани
рендгенском дифракцијом, инфра црвеном спектроскопијом са Фуријеовом трансформацијом и скенирајућом електронском микроскопијом. Калцинисани узорци су синтеровани на 1000 °C са задржавањем од 3 сата у атмосфери ваздуха (CaP1000, CaMgP1000 and CaSrNaP1000). Синтеровани материјали окарактерисани су: рендгенском дифракцијом на поликристалном узорку, инфрацрвеном спекторскопијом са Фуријеовом трансформацијом и скенирајућом електронском микроскопијом са енергетско дисперзивном анализом као и методе комплексне импендансе. Највећа проводљивост добијена је на температури од 700 °C и износи 1.90×10-3 Ω-1cm-1 за мешовито допирани фосфатни материјал (CaSrNaP1000). Добијене активационе енергије проводљивости износе 0.31 eV у температурном опсегу од 500-700 ºC.

AB  - This study correlated the refractive indices (RIs) of unfilled resin mixtures and resin-based composites (RBCs) with color and translucency of conventional and low-shrinkage RBCs. Unfilled resin mixtures based on different ratios of conventional monomers Bisphenol A-glycidyl-methacrylate (BisGMA)/triethyleneglycol-dimethacrylate (TEGDMA) and urethane-dimethacrylate (UDMA)/TEGDMA and a low-shrinkage monomer FIT-852 (FIT, Esstech Inc.)/TEGDMA were used to prepare model RBCs, containing 30 wt % of the organic matrix and 70 wt % of silanated barium-glass fillers (n=1.553, Esstech Inc.). The RIs of resins were measured on an ABBE refractometer, those of cured RBCs using the Becke-line method in immersion oils. Color and translucency were determined using an AvaSpec-2048 (Avantes BV) spectrometer. The RIs of unfilled resin mixtures decreased with increasing amounts of TEGDMA. Cured RBCs had higher RIs than their respective resin mixtures. BisGMA-based composites were more translucent with significantly lower L* values than FIT- and UDMA-based RBCs. The RIs of unfilled resins positively correlated with cured RBCs (p=0.001), as did the RIs with translucency (p=0.001) and color (p=0.008). Resin mixtures and corresponding RBCs based on UDMA and its modified low-shrinkage version, FIT, showed similar optical properties. The RIs of unfilled resins appeared to be good predictors of the RIs of cured RBCs. (c) 2015 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 105B: 7-13, 2017.

AB  - Mesoporous monetite (CaHPO4), obtained by mechanochemical treatment of previously synthesized brushite (CaHPO4 center dot 2H(2)O), was used as efficient adsorbent for the organic pesticide malathion. The structure of brushite was confirmed by Raman spectroscopy. The phase transformation process was investigated by X-ray powder diffraction (XRD) and Fourier transformation infra-red spectroscopy (FTIR). The microstructure and morphology were determined by scanning electron microscopy (SEM) and the nitrogen adsorption-desorption method. It was found that five minutes of milling induces brushite-monetite phase transformation. Adsorption of malathion from aqueous solutions showed that this pesticide can be successfully adsorbed on surface of this material.

AB  - The idea of this paper is to investigate the phase composition and demographic distribution of urinary stones Serbian patients of both sexes. To determine the phase characteristics, we were use a method of X-ray diffraction analysis. X-ray diffraction analysis of the samples indicate the presence of the following phases: Whewelite (CaC2O4 • H2O) and Weddelite (CaC2O4 • 2H2O) from oxalate, Apatite (Ca5(PO4)3X), Brushite (Ca (HPO4) • 2H2O) and Struvite (MgNH4PO4·6H2O) from phosphate, as well as Uricite (C5H4N4O3) and L – cystine (C6H12N2O4S2). The SEM analysis confirmed the obtained structure.
