Conductive pathways in electroconductive biodegradable polymer matrix composites / Provodni putevi kod elektroprovodnih kompozita sa biodegradabilnom polimernom matricom
(Zagreb, Croatia : University of Zagreb, Faculty of Chemical Engineering and Technology, 2016)
The results of experimental studies of the properties of composite materials based on lignocellulosic (LC) and poly(methylmetacrylate) matrices filled with electrolytic copper
powder are presented. Volume fractions of ...
Jute post-industrial waste as carbon nitride support in photocatalytic degradation oftextile dyes under simulated solar light illumination
(Belgrade : Materials Research Society of Serbia, 2023)
Urea-based graphitic carbon nitride (g-C3N4) is thermally exfoliated at 500 °C in the airatmosphere, and nano-carbon nitride (n-C3N4) is obtained. While optical properties are assessedusing UV/Vis DR spectroscopy, structural ...
Synthesis and characterization of new cerium doped phosphate tungsten bronze
(Society of Physical Chemists of Serbia, 2021)
Cerium doped phosphate tungsten bronze (Ce-PWB) was synthetized by phase transformations of CePW12O40x6H2O (Ce-6-PWA) salt. The solid-solid transformations of Keggin's anion of this salt, including dehydration processes ...
Promotion of Supercapacitance of Novel Generation Supercapacitors Based on Lanthanum Strontium Cobalt Oxide and Hydrotermal Ruthenium Oxide
(Zvornik, Republic of Srpska, B&H : Faculty of Technology, 2019)
In this study we report of considerable promotion of supercapacitive performances of ruthenium oxide hosted by perovskite-like structure of rare earth–CoO3 composite and vice versa. Spherical, sub-µm-sized, regular spheres ...
Highly active pectinases from newly isolated Aspergillus tubingensis strain
(University of Belgrade - Faculty of ChemistrySerbian Biochemical Society, 2021)
Pectinolytic enzymes represent a large group of enzymes that catalyze the reactions of depolymerization and deesterification of pectin polysaccharides1. Saprophytic fungi produce pectinases on a large scale for industrial ...
Electrochemical characterization of La0.6Sr0.4CoO3 and La0.6Sr0.4CoO3 doped with RuO2 powders as the next generation supercapacitors
(Bor, Serbia : University of Belgrade, Technical Faculty in Bor, 2017)
In this study, La0.6Sr0.4CoO3 (LSC) powder and LSC doped with 20 wt.% RuO2 were investigated as anode materials for supercapacitor. Spherical submicron particles of La0.6Sr0.4CoO3 have been synthesized by ultrasonic spray ...
Principal component analysis of morphological descriptors for assessment of surface defects induced by extreme conditions
(Association of Metallurgical Engineers of Serbia (AMES), 2023)
Implementation of statistical analysis for monitoring the formation and propagation of defects that occurred due to
exposure of the material to thermal shock and cavitation is presented in this study. Results of two groups ...
