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); ...
Achieving a Superhydrophobic, Moisture, Oil and Gas Barrier Film Using a Regenerated Cellulose–Calcium Carbonate Composite Derived from Paper Components or Waste
(MDPI, 2022)
It has been a persistent challenge to develop eco-friendly packaging cellulose film providing the required multiple barrier properties whilst simultaneously contributing to a circular economy. Typically, a cellulosic film ...
Extraction of polyphenols from orange peel and their controlled release from pH-sensitive hydrogels
(Serbian Chemical Society and Serbian Young Chemists’ Club, Belgrade, Serbia, 2022)
Several million tons of orange peel are generated annually as a result of the industrial
processing of this fruit. Orange peels are rich in polyphenols, that show antioxidant
activity. Hence, converting orange peels into ...
Oxidized jute as a valuable adsorbent for Congo Red from an aqueous solution
(SAGE Publications Ltd., 2022)
The raw jute fabric was oxidized with 0.2% or 0.4% NaIO4 for 60 or 120 min to obtain valuable adsorbents for the textile dye Congo Red (CR). Batch adsorption experiments were carried out as a function of solution pH, contact ...
CONTROLLED RELEASE OF CAFFEINE FROM THREE DIMENSIONAL NETWORKS BASED ON POLY(METACRYLIC ACID) AND CASEIN - ANALYSIS OF THE EFFECT OF CAFFEINE CONCENTRATION ON RELEASE PROCESS
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2022)
Everyday demands for safer and more efficient therapy for many diseases, especially serious ones such as various types of cancer, put various challenges in front of modern science. One of them lies in the fact that numerous ...
Investigating possibilities for synthesis of novel sorbents and catalyst carriers based on ceramics with controlled open porosity / Ispitivanje mogućnosti sinteze inovativnih sorbenata i nosača katalizatora na bazi keramike kontrolisane otvorene poroznosti
(Hemijska industrija, 2022)
The aim of this study was to investigate a possibility of synthesis of porous ceramics with controlled open porosity, which could be used as sorbents and catalyst supports. Two organic additives were used to obtain open ...
Influence of material surface roughness on backscattering in laser scanning
(Faculty of Architecture, Civil Engineering and Geodesy, University of Banja Luka, 2022)
In this paper, the possibility of applying Kirchhoff 's scalar approximation model for determining the backscattering coefficient from rough surfaces is investigated. Surfaces of dielectric and metallic materials, which ...
