A survey on the characterization and biological activity of isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2020)
The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. ...
Structurally and surface-modified alumina particles as a reinforcement in polyester-based composites with an improved toughness
(Springer, New York, 2020)
Commercial gamma - Al2O3 particles, Al2O3 n, and synthesized Al2O3 doped with iron oxide (Al2O3 Fe) were used as reinforcements to enhance the toughness of an unsaturated polyester resin (UPR). Alumina modification with ...
Optimization and kinetic study of anthraquinone dye removal from colored wastewater using soybean seed as a source of peroxidase
(Macedonian Journal of Chemistry and Chemical Engineering, 2020)
As water contamination emerges as a serious threat to the environment, ventures for cleaner and sustainable solutions are continuously being developed. The present study investigates the ability of crude peroxidase extract ...
Optimization of spray drying conditions for production of Achillea millefolium extract powder
(Hemijska industrija, 2021)
In this study, a spray drying process of yarrow (Achillea millefolium L.) liquid extracts was optimized by using the response surface methodology. The study aimed to determine the influence of temperature (120-195 degrees ...
The influence of thermodynamic parameters on alkaline activator of geopolymers and structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 °C for the process of geopolymerization. ...

(Univerzitet u Beogradu - Biološki fakultet - Institut za botaniku i botaničku baštu "Jevremovac", Beograd, 2020)
This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: the diatom alga Eunotia boreoalpina; the saprotrophic fungus Clitocybe truncicola; the liverwort Haplomitrium ...
Simulated Body Fluids Prepared with Natural Buffers and System for Active pH Regulation
(Iranian Institute of Research and Development in Chemical Industries, 2022)
The current study focuses on creating an initial highly alkaline simulated body fluid whose pH can be decreased to a physiological range by adding CO2 (protein-free simulated body fluid) or a combination of CO2 and human ...
Characterisation of biomedical titanium layers deposited by a vacuum plasma spray process
(Materiali in Tehnologije, 2021)
In this paper we will describe the process of the deposition of thick layers of VPS-Ti coating, which is used as a bonding layer for the upper porous Ti coatings on implant substrates. In order to deposit the powder, we ...
Liquid transfer properties of textile fabrics as a function of moisture content
(Savez hemijskih inženjera, Beograd, 2020)
Liquid transport in textile fabrics determines thermal comfort during high physical activity of a person when liquid perspiration is produced and needs to be transferred away from the skin to keep the thermal balance. In ...
Zinc oxide nanoparticles prepared by thermal decomposition of zinc benzenepolycarboxylato precursors: Photoluminescent, photocatalytic and antimicrobial properties / Наночестични прахови цинк-оксида добијени термичком деградацијом цинк-бензенполикарбоксилато прекурсора: фотолуминесцентна, фотокаталитичка и антимикробна својства
(Serbian Chemical Society, 2020)
Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-source precursors at 450 °C in an air atmosphere. The mechanism and kinetics of thermal ...
