AB  - A size-strain line-broadening analysis of the XRPD patterns and Raman spectra for two anatase/brookite (TiO2)-based nanocomposites with carbon (C) was carried out and the results compared with those of a similar sample free of carbon. The crystal structures and microstructures of anatase and brookite, as well as their relative abundance ratio, have been refined from XRPD data by the Rietveld method (the low amount of carbon is neglected). The XRPD size-strain analysis resulted in reliable structure and microstructure results for both anatase and brookite. The experimental Raman spectra of all the samples in the region 100-200 cm-1are dominated by a strong feature primarily composed of the most intense modes of anatase (Eg ) and brookite (A 1g ). The anatase crystallite sizes of 14-17 nm, estimated by XRPD, suggest the application of the phonon confinement model (PCM) for the analysis of the anatase Eg mode, whereas the relatively large brookite crystallite size (27-29 nm) does not imply the use of the PCM for the brookite A 1g mode. Superposition of the anatase Eg mode profile, calculated by the PCM, and the Lorentzian shape of the brookite A 1g mode provide an appropriate simulation of the change in the dominant Raman feature in the spectra of TiO2-based nanocomposites with carbon. Raman spectra measured in the high-frequency range (1000-2000 cm-1) provide information on carbon in the investigated nanocomposite materials. The results from field-emission scanning electron microscope (SEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy and nitrogen physisorption measurements support the XRPD and Raman results.

AB  - Antimony doped barium-stannate dense ceramic materials were synthesized using spark plasma sintering technique out of mechanically activated precursor powders. The influence of various Sb concentrations (x =0.00 – 0.10) on properties of BaSn1-xSbxO3 ceramics was investigated. Relative densities of prepared samples were in the range of (79–96) %. TEM analysis revealed the presence of many dislocations in undoped BaSnO3, and their significant reduction upon doping with Sb. All samples except BaSn0.92Sb0.08O3 exhibit non-linear I-U characteristic, typical for semiconductors with potential barrier at grain boundaries. Low angle grain boundaries found only in BaSn0.92Sb0.08O3 caused the loss of potential barrier at grain boundaries which was confirmed by AC impedance spectroscopy measurements. Consequently, BaSn0.92Sb0.08O3 showed the lowest electrical resistivity and linear I-U characteristic. UV–vis analysis confirmed the increasing of band gap (Burstein–Moss shift) values in all doped samples.

AB  - A total of 15 Navicula taxa were recorded in epilithic
communities occurring in seven rivers of Serbia, all of
which are new to the diatom flora of Serbia. The most
interesting of them are N. splendicula and N. moskalii. When
observing N. splendicula specimens under SEM, we noticed
a characteristic silicate tongue in the center of raphe ends,
which had not been previously reported in the available
literature. The insufficiently researched distribution of
N. moskalii and scarce autecological information on the
taxon prompted us to provide new details about the species
in this study. These findings clearly indicate the need for
further comprehensive research that would provide new
information on rare taxa.

based on 55 different localities that included rivers, streams, channels, accumulations and salt marshes throughout Serbia. The results of this study expanded the diatom checklist by 80 taxa, including two new recorded genera (Fistulifera and Microfissurata) for Serbia. The data were obtained by combining light microscopy (LM) and scanning electron microscopy

AB  - The main objective of this paper is to report new
information about the distribution and ecology of a
recently described diatom species, Geissleria gereckei.
The opportunity for updating the information on the
distribution and ecology of the species was provided by
the finding of well-developed G. gereckei populations on
the lithic material and bryophytes in the Raška and Mlava
rivers (Serbia). For several years after the first description,
G. gereckei has been known only from the type locality
and from another spring in the Dolomiti Bellunesi National
Park (the south-eastern Alps). After accurate LM and SEM
observations, we provide evidence for the occurrence
of the species also in the two above-mentioned rivers in
Serbia, as well as in the south-western and south-eastern
Alps. After an extensive literature search, it appears that the
species is known with certainty only from these sites. Our
observations and details from the literature suggest that
the species is able to occupy a much broader ecological
niche than the very-specific one observed at the time of
discovery. The two main determinants for the species’
occurrence appear to be the carbonate nature of the
catchments or aquifers, and the ability of the species to
be competitive in habitats or microhabitats exposed to
seasonal desiccation.

AB  - The genus Navicula was originally described in 1822 by Bory de St. Vincent. The concept of Navicula has changed from extremely heterogeneous collective genus to a narrowly defined, apparently homogeneous genus. The group Navicula sensu stricto involves 250-300 species and the great majority of them live in fresh, inland waters, and few inhabit brackish waters (Lange-Bertalot 2001).
Knowledge about diatom biodiversity increase as a result of a more detail morphometric analysis of the frustula by light (LM) and scanning electron microscopy (SEM).
Navicula splendicula was described by Van Landingham (1975). According to Lange-Bertalot (2001) it is known to inhabit southern and central Europe, with certainty. Distribution of N. splendicula from 2001 till today become wider, but in published papers SEM micrographs, as well as the dimensions of frustula, were not given and specified. LM and SEM observation of species from Serbia (Rasina and Vrla rivers) showed a variation from literature data regarding dimensions of frustula and variability of the ultrastructure of the central raphe ends.
The poster illustrates all differentiating characters with brief notes on the ecology of the N. splendicula from two rivers in Serbia.

AB  - The Rasina River is right tributary of the Zapadna Morava River, situated in central Serbia. The samples were collected in spring (April), summer (July) and autumn 2011, from 6 localities along the river at an altitudes between 640 – 704 m a.s.l. Sampling sites are located before and after trout pond. Epilithic samples were scraped from the surface of stones by brush. Light microscope observations and micrographs were made using a Zeiss AxioImagerM.1 microscope with DIC optics and AxioVision 4.8 software. At least 400 valves were counted in order to calculate relative abundance (%) of each taxon. The biological assessment of water quality was performed calculating diatom indices by OMNIDIA 5.3 software.
A total of 166 taxa belonging to 45 genera were identified in the studied samples. The most numerous were taxa of genus: Nitzschia (26), Navicula (22) and Gomphonema (15). The dominant taxa during spring were Achnanthidium pyrenaicum and Diatoma ehrenbergii, during summer were A. pyrenaicum and Cocconeis placentula var. lineata and during autumn was only C. placentula var. lineata. Diatom richness before trout farm was higher than after, which confirms its impact. The higest diversity was in spring and constantly decreasing through seasons.
The Rasina River was characterized by good to very good ecological status of water, with slightly differences between the values of the diatom indices during the seasons (spring, summer, autumn, respectively).
Fish feed remains can cause enrichment of the water with nutrients (in the form of ammonia, phosphorus, nitrogen) and most often leads to eutrophication which can be seen on the basis of the dominant species during the seasons. Change of dominant species between the seasons in the Rasina River was correlated with the values of nutrients.
