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 ...
Influence of fruit juice addition on quality of fermented whey-based beverage
(Novi Sad : University, Institute of Food Technology, 2014)
The aim of this study was to evaluate the influence of fruit juice addition on the quality of fermented whey-based beverages that contain commercial ABY-6 starter culture. Milk (30%) and Cornelian cherry fruit juice (30%) ...

(Amer Chemical Soc, Washington, 2020)
Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4and Na2HPO4at T = 298.15 ± 0.01 K, at NaH2PO4ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and 1), ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Semi-interpenetrating networks based on (Meth)acrylate, itaconic acid, and poly(vinyl pyrrolidone) hydrogels for biomedical applications
(Springer Singapore, 2020)
In this study, three series of semi-interpenetrating networks were synthesized based on 2-hydroxyethyl methacrylate (HEMA), 2-hydroxyethyl acrylate (HEA), itaconic acid (IA), and poly(vinyl pyrrolidone) (PVP) as interpenetrating ...
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 ...
Repair welding procedure and techno-economic analysis of burner pipe
(Structural Integrity and Life-Integritet I Vek Konstrukcija, 2021)
The selection of the electrode for repair welding is one of the activities needed before repairing machine parts. In this case, damages that have occurred in a burner pipe welded joint during manufacture or previous repair ...
Morphological assessment of cavitation caused damage of cordierite and zircon based materials using principal component analysis
(Elsevier Ltd, 2023)
The pattern recognition approach, explored by this study, applies the principal component analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation and propagation of the cracks and ...
Synthesis, characterization and SAR studies of bis(imino)pyridines as antioxidants, acetylcholinesterase inhibitors and antimicrobial agents
(Academic Press Inc Elsevier Science, San Diego, 2020)
In this study we synthesized a series of sixteen bis(imino)pyridines (BIPs) starting from 2,6-diaminopyridine and various aromatic aldehydes, and evaluated their antioxidant, antibacterial, antifungal and acetylcholinesterase ...
Biocompatibility and antibiofilm activity of graphene-oxide functionalized titanium discs and collagen membranes
(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 ...
