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); ...
Studying the influence of common wet processes on the quality of 1 × 1 rib cotton/elastane knitted fabrics
(SAGE Publications Ltd, 2022)
This research studied the influence of common wet processes (i.e. bleaching, dyeing, or softening) on the quality of 1 × 1 rib cotton/elastane knitted fabrics. The changes in their structural (thickness, weight, and stitch ...
Modification of CaCO3 and CaCO3 pin-coated cellulose paper under supercritical carbon dioxide-ethanol mixture for enhanced NO2 capture
(Environmental Science and Pollution Research, 2022)
In this work, we examine two modifications of fine-ground calcium carbonate material (GCC) in order to enhanced sorption of NO2 and subsequent reaction properties toward NO2-/NO3- formation by firstly exposing the GCC to ...
Hydrolysis of soft wheat flour: Enhanced functional properties and the effect of starch on allergenicity reduction
(Journal of Food Processing and Preservation, 2022)
The possibility to utilize Alcalase to hydrolyze soft wheat flour (SWF) containing high concentration of solids (i.e. starch) and the effect of its presence was investigated. At a degree of hydrolysis of 23.49% +/- 0.64%, ...

Recycling of metals from renewable energy sources to alloys used in green energies / Recikliranje metala iz obnovljivih izvora energije u legure koje se koriste u zelenim energijama
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije SMEITS, Društvo za obnovljive izvore električne energije, 2022)
Recycling specific e-waste from renewable energy provides an opportunity to integrate it with a pyrometallurgical production process of various types of non-ferrous alloys. One type of alloy is used for brazing of different ...
J-integral Analysis of the Simulated Heat-affected Zone of the Elevated-temperature Martensitic Steel
(Experimental Techniques, 2022)
Due to its superior strength at high temperatures P/T91 steel is often applied in the chemical, petrochemical and fossil-fired power generation industries. The high strength is achieved by a suitable martensitic microstructure ...

(Elsevier Inc., 2022)
The aims of the study were: 1) to evaluate the effect on biofilm formation of barrier membranes and titanium surfaces coated with graphene-oxide (GO); 2) to analyze the connection between the superficial topography of the ...
Beech sawdust based adsorbents for solid-phase extraction of pesticides and pharmaceuticals
(Serbian Chemical Society, 2022)
Carbonaceous solid-phase extraction (SPE) sorbent, efficient in isol-ation and enrichment of multiclass pesticides and pharmaceuticals from water, was synthesized starting from cheap waste beech sawdust and using KOH as ...
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, ...
