Polyphenol extraction in microwave reactor using by-product of Thymus serpyllum L. and biological potential of the extract
(Elsevier GmbH, 2022)
In the present study, polyphenol extraction from Thymus serpyllum by-product (herbal dust) in microwave reactor was optimized through varying extraction time, ethanol concentration and solid-to-solvent ratiovia determination ...
TiO2 nanotubes film/FTO glass interface: Thermal treatment effects
(ETRAN, 2022)
Pure Ti films deposited by radio-frequency magnetron sputtering on FTO glass were anodized to fabricate TiO2 nanotubes (NTs) arrays. The TiO2 NTs/FTO samples were sintered at 450, 550 and 630°C, in ambient air. The thermal ...
Influence of boron doping on characteristics of glucose-based hydrothermal carbons
(Journal of the Serbian Chemical Society, 2022)
In this study, the influence of boron doping on structural and surface properties of carbon material synthesized by a hydrothermal method was investigated, and the obtained results were compared with the previously published ...
Alkali Treated Jute Fabrics Suitable for the Production of Inexpensive Technical Textiles
(Korean Fiber Society, 2022)
This work aimed to obtain jute fabrics suitable for the production of inexpensive technical textiles by using simple alkali treatments. The influences of alkali concentration (1–17.5 % NaOH) and treatment duration (5–30 ...
Thermal extraction of pectin from waste apple pomace using choline chloride based eutectic solvents
(Serbian Chemical Society and Serbian Young Chemists’ Club, Belgrade, Serbia, 2022)
Processing of waste by-products of agricultural origin generated by different kinds of
industries can entail environmental problems. Waste apple pomace (biomass) could play
an important role in pectin production, offering ...
Modification of cellulose-based waste materials for removal of methylene blue from wastewater
(Belgrade : Society of Physical Chemists of Serbia, 2022)
Different natural fibers and yarns (hemp, flax, and cotton), obtained as a waste from textile industry,
were used for the removal of methylene blue from aqueous solution. In attempt to increase the
adsorption efficiency, ...
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 ...
