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 ...

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 ...

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, ...
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 ...
Plasmonic Crystals with Conical Perforations as Multipurpose Optical Elements
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Plasmonic crystals exhibit excellent waveguiding and extreme light localizing properties. However, if additionally perforated, their structure assumes vastly enhanced functionality and becomes the basis for e.g. double ...
Electrochemical characterization of cobalt phases onto alumina supported cobalt catalyst
(Belgrade: Serbian Ceramic Society, 2021)
This work describes the possible application of cyclic voltammetry (CV) for obtaining information about cobalt phases onto alumina supported cobalt catalysts.Starting from the same amount of ingredients, two ...
