Nanocomposite Hydrogels Based on Poly(vinyl alcohol) and Chitosan with Silver Nanoparticles and Graphene Aimed for Wound Dressing Applications
(Belgrade : Serbian Academy of Sciences and Arts, 2018)
In this work, we prepared hydrogels based on PVA, CHI and Gr, and used them
as a porous matrix to synthesize silver nanoparticles by an in situ electrochemical
method [3,4]. The hydrogels were prepared from PVA/CHI/Gr ...
Enzyme-assisted extraction of various bioactive components from blackcurrant (Ribes nigrum)
(Croatian Society of Food Technologists, Biotechnologists and Nutritionists, Zagreb, Croatia, 2022)
According to experts, berries are a major source of phytochemicals, disease-fighting
components, which can help to boost the immune system and lower the risk of many agingrelated conditions. The simplest way to isolate ...
Synthesis and characterization of dental inserts based on calcium-phosphate, doped with magnesium, strontium and fluorine ions
(Belgrade : Institute of Technical Sciences of SASA, 2022)
Structure–property correlations for composite hydrogels based on poly(methacrylic acid) and high concentrations of LTA zeolite
(Elsevier, 2024)
High concentrations of LTA zeolite (27-52mass%) were embedded in poly(methacrylic acid) (PMAA) matrix to obtain composite hydrogels with porosity and active sites originating from both components. Substandard mechanics of ...
Primena ravnoteže tečnost-tečnost ternarnih vodenih rastvora u separacionim procesima / Liquid-liquid equilibrium of the ternary water solutions system in separation processes
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2021)
Zbog globalnog trenda povećanja potrošnje energenata, kao i njihove cene, teži se ka tome da
se ispitaju nove mogućnosti zamene klasičnih energetski zahtevnih separacionih procesa zasnovanih
na isparavanju lakše isparljivih ...
Removal of xenobiotics from wastewaters using photolysis under sun-light irradiation: experimental approach and process design
(Banja Luka : University in Banjaluka, Faculty of Technology, 2023)
Conventional wastewater treatment processes are increasingly difficult to fulfill strict standards of
achieving the required quality. Therefore, it is necessary to apply processes that in an efficient and
economically ...
Effect of temperature and specimen orientation on Charpy impact toughness
(Elsevier B.V., 2022)
Steel grade 14MoV6 3 is used for manufacturing of boilers and steam pipelines designed for steam temperatures up to 560°C. This paper presents the experimental analysis which included impact toughness test. The analysis ...
Environmentally friendly hydrogels for medical and pharmaceutical applications
(Savez hemijskih inženjera Srbije, 2024)
The Polymer group of the Faculty of Technology and Metallurgy University of Belgrade deals with environment-sensitive hydrogel as carriersfor biomedical applications, including drug delivery, wound healing, and regenerative ...
Preparation of cellulosic fibers with biological activity by immobilization of trypsin on periodate oxidized viscose fibers
(Springer, Dordrecht, 2014)
In this study, a biologically active fibrous material was designed by immobilizing trypsin on viscose fibers. The viscose yarn was first oxidized with sodium periodate to produce aldehyde groups and then employed as a ...
Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
