Determining the caloric potential of wooden plant species with the goal to protect and improve the environment
(Beograd: Ecologica, 2022)
Many countries are increasing the share of renewable and sustainable energy with the
basic goal to reduce the volume of fossil fuels whose harmful impact on the environment
is significant. The production and use of biomass ...
Assessment of the faecal contamination along the Sava River and identification of pollution sources
(Macedonian Ecological Society, 2016)
The contamination of water by faecal pollution leads to exposure to pathogens via drinking water
production, recreation or irrigation. However, monitoring of microbiological quality of surface waters
is quite neglected ...
Raman microspectroscopy: toward a better distinction and profiling of different populations of dental stem cells
(Medicinska Naklada Zagreb, 2019)
Aim To characterize stem cells originating from different dental tissues (apical papilla [SCAP], dental follicle [DFSC], and pulp [DPSC]) and test the capacity of Raman microspectroscopy to distinguish between the three ...
Structural, morphological and optical study of nanostructured TiO2/Fe2O3 thick film
(Bor : Technical Faculty, 2013)
Thick films of nanostructured TiO2 (60 wt%) and alpha-Fe2O3 (40 wt%) were fabricated by screen printing technology on an alumina substrate. Samples were sintered in the temperature range 750-1350oC in air. Thick film paste ...
INFLUENCE OF DOPANTS ON BARIUM BISMUTH TITANATE ELECTRICAL PROPERTIES
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2013)
The Aurivillius structure has capability to host ions of different size, so a large number of different dopants can be accommodated in the BaBi4Ti4O15 (BBT) lattice. It was detected that various substitutions of Bi3+ and ...
"Blue-green" corridors as a tool for erosion and stream control in highly urbanized areas - case study of Belgrade city
(Wallingford, Oxfordshire : International Association of Hydrological Sciences, 2014)
Highly urbanized areas constantly need new surfaces for building of commercial, residential or infrastructure objects. Belgrade, the capital of Serbia, is a large regional centre with a population of 2 000 000 dwellers, ...

Kudreč I, Kudreč II, Topola i Markovačko jezero, na osnovu kvalitativnog i kvantitaivnog
sastava riblje zajednice. Ustanovljeno ...
Effect of Rubber Treatment on Compressive Strength and Modulus of Elasticity of Self-Compacting Rubberized Concrete
(World Academy of Science, Engineering and Technology, 2021)
This paper investigates the effects of different
treatment methods of rubber aggregates for self-compacting concrete
(SCC) on compressive strength and modulus of elasticity. SCC
mixtures with 10% replacement of fine ...
STRUCTURAL CHARACTERISATION AND ORIENTATION OF CELL WALL POLYMERS IN MAIZE LEAVES
(University of Belgrade, Technical Faculty in Bor, 2019)
Cell wall can be considered as a nano-composite in which cellulose, lignin and hemicelluloses are
interconnected in a specific manner. Mechanical and physical propreties of plant fibres are dependent
on the orientation ...
Chemical modification of hemicellulose isolated from corncobs to obtain hydrogel for enzyme immobilization
(Society of Physical Chemists of Serbia, 2021)
Hemicellulose rich in xylan was isolated from corncobs. Functional groups were introduced first by
carboxymethylation and then by coupling with tyramine via carbodiimide-mediated reaction.
Obtained hydrogel was tested ...
