An updated list of Serbian diatom flora – new recorded taxa
(Serbian Biological Society, 2018)
Diatoms are a widespread group of organisms with well-known ecological preferences. Knowledge of their diversity is of great importance for assessing the environmental status of different aquatic ecosystems. The present ...
Uncertainty of using habitat fidelity in biomonitoring based on benthic diatoms - the Raška River case study
(Springer, 2018)
Epilithic diatoms are frequently recommended for river biomonitoring, while much less emphasis is placed on epiphytic communities.
This study considers use of epiphytic and epilithic diatom communities from the Raška River ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
Comparative Study of the Mineral Composition and Its Connection with Some Properties Important for the Sludge Flocculation Process-Examples from Omarska Mine
(MDPI, 2018)
Studied sludge samples are composed of major goethite and quartz; less clay minerals;
and minor magnetite, hematite, clinochlore and todorokite. They have quite similar qualitative,
but different semi-quantitative ...
Comparison of the crystallographic-chemical characteristics of sphalerites from the Kiževak ore deposit with some other deposits, part II: Construction of the four-component a0-FeS-P-T diagram (option I) and determination of the formation conditions / Поређење кристалографско-хемијских карактеристика сфалерита из рудног лежишта кижевак са неким другим рудним лежиштима, део ii: онструисање четворо-компонентног a0-fes-p-t дијаграма (опција I) и одређивање услова постанка
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of Serbia, 2018)
Same as in the I part of these investigations (Tančić, 2018), crystallographic-chemical characteristics for sphalerites from the ore deposit Kiževak were used for the comparison with the corresponding characteristics of ...
Laws of evolution parallel the laws of thermodynamics
(Elsevier, 2018)
We hypothesize that concepts from thermodynamics and statistical mechanics can be used to define summary statistics, similar to thermodynamic entropy, to summarize the convergence of processes driven by random inputs subject ...
Thermodynamics of hydrolysis of cellulose to glucose from 0 to 100 °C: Cellulosic biofuel applications and climate change implications
(Elsevier, 2018)
Hydrolysis of cellulose to glucose is a key reaction in renewable energy from biomass and in mineralization of soil organic matter to CO2. Conditional thermodynamic parameters, ΔhydG’, ΔhydH’, and ΔhydS’, and equilibrium ...
Silicon Thin-Film Solar Cells Approaching the Geometric Light-Trapping Limit: Surface Texture Inspired by Self-Assembly Processes
(American Chemical Society (ACS), 2018)
A new device design of microcrystalline silicon thin-film solar cell allows for approaching the geometric light-trapping limit. The solar cell is based on triangular textured surfaces in combination with optimized front ...
Nanophotonic design of perovskite/silicon tandem solar cells
(Royal Society of Chemistry, 2018)
The perovskite material system allows for the realization of perovskite/silicon tandem solar cells with high energy conversion efficiencies at low cost. To realize such solar cells, the device geometry, the device processing, ...
Analysis of Efficacy of the Process of Remediation of Landfill Site Soil Contaminated with Leachate using Material Flow Analysis / Analiza efikasnosti procesa remedijacije zemljišta deponijskog lokaliteta kontaminiranog procednim vodama primenom analize tokova materijala
(Univerzitet u Beogradu - Tehnički fakultet u Boru, 2018)
There are two possible cases concerning non-sanitary municipal solid waste landfills due to failure to meet requirements with respect to impermeability and thickness of geological barrier as well as absence of implementation ...
