Fractal reconstruction of fiber-reinforced polymer composites
(Belgrade : Serbian Chemical Society, 2021)
Polymers offer the possibility of different reinforcement incorporation due to a broad range of
chemical structures.Along with this feature, their light weight and processing ease made them
a class of materials that have ...
Bioleaching of metals from printed pc motherboard by acidithiobacillus ferrooxidans
(RemTech Europe, 2021)
Electronic waste is the fastest growing waste category. This emphasizes the need for effective electronic waste recycling strategies. Recycling of electronic waste is crucial not only from the viewpoint of waste treatment ...

Forced periodic reactor operation: Analysis of process and forcing parameters exploiting the nonlinear frequency response method
(WILEY-VCH, 2020)
Continuous chemical reactors are mostly operated under steady-state conditions. However, theoretical studies reveal that forced periodic operation (FPO) can lead to better performance. To predict and optimize FPO, the ...
Influence of sintering time on density properties and SEM analysis of cordierite-based ceramics / Uticaj vremena sinterovanja na gustinu i SEM analiza kordijeritne keramike
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
Characterization of oil pollutants in soil and sediments in the vicinity of a heating plant – alluvial sediments of the Sava river, Belgrade, Serbia
(Croatia : Association for Promotion of Holistic Approach to Environment, 2021)
The aim of this research was characterization of oil pollutants in the soil and sediments
in the vicinity of one of the largest district heating plants in Belgrade (Capital of Serbia).
The soil and sediment samples (109 ...

(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
Investigation of physicochemical properties and potential biological activity of 2-pyridine-(thio)carbohydrazone derivatives
(Programme and the book of abstracts, 14th International Scientific Conference Contemporary Materials 2021, 2021)
Carbohydrazones and their thio analogs represent compounds obtained by condensation of carbohydrazide and thiocarbohydrazide with carbonyl compounds. Due to their structure, relatively simple synthesis, and high reactivity, ...
Development of novel labelling system for microplastics
(Oficyna Wydawnicza Politechniki Rzeszowskiej, 2021)
Microplastics are microscopic pieces (<5 mm) of plastic materials that can be found at
every corner of our planet. Two ways of their release into the environment can be discerned: primary and secondary microplastics. While ...
Impregnation of cellulose acetate with natural bioactive compounds using supercritical carbon dioxide
(Book of abstracts - 7th International Congress of the European Polysaccharide Network of Excellence, 2021)
Porous acetate cellulose (CA) beads were tested as carriers for thymol, eugenol and
carvacrol, natural compounds well known for their biological activity. For this purpose,
selected compounds were impregnated into CA ...
