The study of composition-properties relationships for composite hydrogels based on poly(methacrylic acid) and high concentrations of MFI zeolite
(Elsevier, 2023)
High concentrations of hydrophobic MFI zeolite (26.0–51.3 wt%) were successfully embedded in poly(methacrylic acid) (PMAA) network in simple, one-pot synthesis of PMAA-MFI composite hydrogels. The effects of zeolite ...
Effect of chemical modifications and coating with Cu-based nanoparticles on the electro-physical properties of jute fabrics in a condition of high humidity
(Elsevier B.V., 2022)
The electro-physical properties of raw, alkali and oxidatively modified jute fabrics were investigated as complex phenomena of the interactions between the fabrics’ chemical composition, carboxyl group content, crystallinity, ...
Micro-kinetic modelling of photocatalytic CO2 reduction over undoped and N-doped TiO2
(Royal Soc Chemistry, Cambridge, 2020)
CO2 photoreduction is studied using in-house synthesized undoped and N-doped TiO2 nanoparticle photocatalysts. Comparison with the commercial P25 TiO2 powder shows that the synthesized samples are more effective. P25 ...
Enhanced Lactic Acid Production by Adaptive Evolution of Lactobacillus paracasei on Agro-industrial Substrate
(Springer, New York, 2019)
The aim of this study was to perform the adaptation of Lactobacillus paracasei NRRL B-4564 to substrate through adaptive evolution in order to ensure intensive substrate utilization and enhanced L (+)-lactic acid (LA) ...
Structure and properties of TEMPO-oxidized cotton fibers / Struktura i svojstva TEMPO-oksidisanih vlakana pamuka
(Association of the Chemical Engineers of Serbia, 2012)
In this paper, the influence of the catalytic oxidation using water soluble and stable nitroxyl radical 2,2',6,6'-tetramethylpiperidine-1-oxyl (TEMPO) on the structure and properties of cotton fibers was studied. In ...
Casein-poly(methacrylic acid) hybrid soft networks with easy tunable properties
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The design of complex polymeric materials with predefined task-specific properties meets challenging issues: to establish synthesis-structure-properties relationship, as well as to understand the arrangement and interactions ...
Steroid-based tracing of sewage-sourced pollution of river water and wastewater treatment efficiency: Dissolved and suspended water phase distribution
(Elsevier B.V., 2022)
In this work, the environmental distribution of steroid compounds and the level of sewage-derived contamination were assessed using sterol ratios in the confluence area of two major rivers in the Serbian capital, where raw ...

(SMEITS - Savez Mašinskih i Elektrotehničkih Inženjera i Tehničara Srbije, 2022)
The advances in the technology of cheap and low power consumption microelectronic components have lead to the expansion of wireless technologies in the past two decades. One of the most important shortcomings of all wireless ...
BIOBASED COMPOSITE MATERIALS OBTAINED FROM UNSATURATED POLYESTER RESINS AND WASTE COFFEE
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS) Društvo za procesnu tehniku, Beograd, Srbija, 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 ...
Chemometric Optimization of Solid-Phase Extraction Followed by Liquid Chromatography-Tandem Mass Spectrometry and Probabilistic Risk Assessment of Ultraviolet Filters in an Urban Recreational Lake
(Frontiers Media S.A., 2022)
Solid-phase extraction (SPE) of eleven ultraviolet filters (UVFs): benzophenone-1 (BP-1); benzophenone-3 (BP-3); benzophenone-4 (BP-4); isoamyl p-methoxycinnamate (IAMC), homosalate (HMS); 4-hydroxybenzophenone (4-HB); ...
