Two types of integrated heaters for synthesis of TiO2 nanoparticles in microreactors
(Belgrade : ETRAN Society, 2018)
In this paper it is shown how we fabricated two types of heaters for microreactors which are used in synthesis of TiO2 nanoparticles. We used standard photolithographic processes to design gold and p-type heaters diffused ...
Silver(I) Adsorption on Magnetic Macroporous Chelating Polymer
(Society of Chemists and Technologists of Macedonia, 2018)
Environmental poisoning due to the emission of waste silver electrical and electronic
industries, jewelry, photography and dentistry, in the last few decades has been of growing concern. The most effective methods for ...
Electrochemical Synthesis of Flower like Magnesium Oxide/Hydroxide from Magnesium Nitrate Melt
(International Society of Electrochemistry, 2018)
The magnesium oxide (MgO)/magnesium hydroxide (Mg(OH)2) in recent years have received
considerable attention as one of the nanomaterials intended for specific application. The interest in this material is standing from ...
Konzervacioni status makrofitske vegetacije u kopovima šljunka u plavnom području donjeg toka reke Drine
(Srpsko društvo za zaštitu voda, 2018)
Human-made aquatic habitats, such as gravel pit lakes could be alternative habitats and biodiversity refugia for aquatic biota. The aim of this study was to determine conservation value of gravel pit lakes in the Drina ...
The role of invasive hydrophytes in structuring macrophyte assemblages in the newly‑formed gravel pit lakes
(Bucharest, Romania : Editura Universităţii din Bucureşti, 2018)
Newly‑formed aquatic habitats, such as gravel pit lakes in river floodplains are usually colonised by macrophyte species few years following the gravel extraction. Together with native species, invasive hydrophytes may ...
The role of hydrological regime in structuring macrophyte assemblages in gravel pit lakes along the Drina river floodplane (Serbia)
(Belgrade : Institute of Botany and Botanical Garden Jevremovac, Faculty of Biology, 2018)
Hydrological regime plays an important role in structuring macrophyte vegetation in highly connected fl oodplain lakes, such as gravel pit lakes connected to the main river channel. If the dominant hydrological drivers are ...
Chara globularis – Chara connivens – Chara contraria: more insights from morphology and genetics
(The International Research Group on Charopytes (IRGC), 2018)
Most field charophytologists have experienced that the morphology of Chara specimen can be intermediate” between two different species. We collected a Chara sample in lake Sava, close to Belgrade, Serbia. The habitus of ...
Investigation of the Structure and Surface Properties of Novel Polyurethane Networks Based on Polycaprolactone
(Society of Chemists and Technologists of Macedonia, 2018)
Polyurethane networks (PUN) represent versatile materials which are usually consisted of
different hard (HS) and soft segments (SS). They possess very good mechanical, thermal and surface
properties. Such properties ...
The effect of some mixed tetraoxanes on germination and antioxidants in maize seedlings
(Society of Physical Chemists of Serbia, 2018)
Germination is one of the most sensitive phases in growth of agricultural plants, where optimal conditions in temperature and water accessibility are required. Seedlings are particularly sensitive to environmental stressors, ...
Gallic acid effect on the Briggs-Rauscher reaction dynamics
(Society of Physical Chemists of Serbia, 2018)
The effect of different concentration of gallic acid (GA) on the oscillatory behavior of the Briggs-Rauscher (BR) reaction is reported. In this work, the sample was injected before the start of oscillations. The main effect ...
