Development and characterization of composite pectin/sodium alginate films crosslinked with zinc ions
(Fourteenth Young Researchers Conference – Materials Science and Engineering, 2015)
In this paper, physico-chemical and antimicrobial properties of films based on pectin/sodium
alginate blends crosslinked by zinc ions were investigated. The polyglycerol was used as
plasticizer. The blending of pectin ...
Investigation of antioxidant activity of 6-hydroxy-6-methyl-2-pyridones / Ispitivanje antioksidativne aktivnosti azo boja na bazi 6--hidroksi-4-metil-2-piridona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2022)
Considering a significant antioxidant activity of 6-hydroxy-6-methyl-2-pyridones, in this paper four series of arylazo pyridone dyes were subjected to antioxidant ABTS assay. Firstly, preliminary tests were conducted at ...
Analysis and interpretation of the micromechanical properties measurements of electrodeposited nickel coatings on different substrates.
(Belgrade : Academy of Criminalistic and Police Studies, 2020)
Fine-grained nickel coatings were electrodeposited by direct current (dc) regime onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single crystal (100)-oriented silicon. These composite ...
Optimization of Bioreactor Cultures of Glioblastoma Cells Immobilized in Alginate Microfibers
(Institute of Technical Sciences of SASA, 2021)
Glioblastoma is the most common and aggressive malignant brain tumor in adults. Existing
treatment choices that include surgery, radiation and chemotherapy are not successful in
long-term survival, while development of ...
Purification of waste water using ozonization / Prečišćavanje otpadnih voda primenom ozonizacije
(Beograd : Beogradska politehnika, 2019)
Due to the development of industry and population growth during the in recent years, there are problems with wastewater from production that needs to be addressed in an environmentally and economical way. All wastewaters ...
Artificial Neural Network for Composite Hardness Modeling of Cu/Si Systems Fabricated Using Various Electrodeposition Parameters
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Copper coatings are produced on silicon wafer by electrodeposition (ED) for various cathode current densities. The resulting composite systems consist of 10 μm monolayered copper films electrodeposited from sulphate bath ...
Antibacterial activity of Cu-based nanoparticles synthesized on the cotton fabrics previously modified with succinic and citric acids

U ovom radu je diskutovana mogućnost in situ sinteze nanočestica na bazi Cu na pamučnim
tkaninama prethodno modifikovanim ćilibarnom i limunskom kiselinom u cilju dobijanja
tekstilnih nanokompozita sa antibakterijskom ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
Sinergetski efekat aditiva na morfološka i mikromehanička svojstva bakarnih prevlaka na različitim podlogama
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2016)
Tanki bakarni filmovi debljine 10 μm deponovani su na hladno-valjanim supstratima od bakra i mesinga procesom elektrohemijske depozicije iz laboratorijski napravljenog sulfatnog kupatila sa dodatkom različitih aditiva ...
Forced periodic reactor operation
(Max Planck Institute, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
