The behavior of cerium doped phosphate tungsten bronze in Briggs-Rauscher oscillatory reaction
(Serbian Ceramic Society, 2022)
The Briggs-Rauscher (BR) reaction is an oscillating reaction in which the oxidation of malonic acid (CH2(COOH)2) in the presence of hydrogen peroxide (H2O2) and potassium iodate (KIO3) is catalyzed with a metal ion (usually ...
Biobased composite materials obtained from unsaturated polyester resins and waste coffee / Kompozitni materijali na bazi nezasićenih poliestarskih smola dobijenih iz bioobnovljivih izvora i otpadne kafe
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS)Društvo za procesnu tehniku, 2022)
Replacing styrene with biobased monomers to produce fully biobased unsaturated polyester
resins (UPRs) turned out to be quite a challenging task. Styrene has been recognized as a hazardous and a potentially carcinogenic ...
Electrochemical behavior of different types of alumina
(Elsevier, 2021)
This work presents the investigation of electrochemical properties of three alumina samples with different structure and crystal water content. The samples were characterized by XRD and FTIR-ATR analysis, confirming the ...
Recycled aggregate mortar made with the recycled concrete aggregate and fly ash
(Belgrade : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS)Belgrade : Society for Renewable Electrical Power Sources, 2022)
With the aim of sustainable development of the construction industry, a large number of theoretical and practical research is currently being carried out on the possibilities of using various recycled materials in cement ...
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 ...
The Effect of Glycol Derivatives on the Properties of Bio-Based Unsaturated Polyesters
(MDPI, 2022)
The scope of the present study was to prepare fully bio-based unsaturated polyester resins (UPRs) with comparable properties to the commercial formulations. The focus was set on the determination of the optimal prepolymer ...
Green pH- and magnetic-responsive hybrid hydrogels based on poly(methacrylic acid) and Eucalyptus wood nanocellulose for controlled release of ibuprofen
(Springer, 2021)
pH- and magnetic-sensitive hybrid hydrogels based on poly(methacrylic acid) (PMAA), nanocellulose (NC), carboxymethyl cellulose (CMC) and magnetite particles (MN) were prepared as ibuprofen delivery system. NC was isolated ...
Basic principles of 3 D concrete printing in the light of sustainable development
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
Although conservative, the construction industry must be transformed in line with new technologies. Adopting the concept of 3D printing can provide a handful of benefits in terms of creativity, flexibility, less waste ...
Exoinulinase gene expression in Aspergillus welwitschiae FAW1 induced by different carbon sources
(University of Belgrade - Faculty of ChemistrySerbian Biochemical Society, 2022)
Fungal inulinases have wide application in industrial biotechnology, and it is presumed that their expression is regulated at the transcriptional level via promoter. It is also known that different sugars have an inducing ...
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 ...
