POLYURETHANE-BASED NANOCOMPOSITE FOR BIOMEDICAL APPLICATION
Hydrogels have emerged as promising materials in regenerative medicine due to their biocompatibility and tunable properties. Polyurethane (PU), a versatile polymer, is renowned for its excellent mechanical properties and stability. However, its inherent hydrophobicity limits its application in biomedical fields. To overcome this limitation, polyure...

IMPACT OF MIDDLE BLOCK COMPOSITION ON THE THERMAL BEHAVIOUR OF POLY(L-LACTIDE)-BASED TRIBLOCK COPOLYMERS
Poly(L-lactide) (PLLA), a biodegradable polymer with properties comparable to conventional plastics, is limited by its inherent brittleness and thermal instability. This study explores the enhancement of PLLA properties through the synthesis of ABA-type block copolymers with distinct soft middle blocks—polyester poly(methylricinoleate) (PMR) ...

DETERMINATION OF THE CONTENT OF HEAVY METALS AND NITRITES IN MEAT PRODUCTS (PATES AND MEAT SPREADS) FROM THE MARKET OF THE REPUBLIC OF SRPSKA
Animal-based food is significant for human nutrition as it represents an easily digestible source of high-quality proteins, fatty acids, fat-soluble vitamins, and energy. Throughout evolution, humans developed anatomical, metabolic, and biochemical adaptations in the digestive tract, increasing dependence on nutritionally valuable food, such as a...

ASSESSING BISPHENOL A DEGRADATION VIA ELECTRO-FENTON PROCESS: THE ROLE OF LACTIC ACID AS AN INDICATOR
Bisphenol A (BPA) is a commonly used industrial chemical in the manufacturing of plastics and resins; however, its endocrine-disrupting properties pose serious health risks to living organisms. By interfering with hormonal balance, BPA can contribute to reproductive and developmental problems. Due to its extensive use, BPA remains prevalent in the ...

THE INFLUENCE OF DOUBLE LAYERED OXIDE (Fe/Al LDO) NANOPARTICLES ON THE PROPERTIES OF COPPER-BASED COMPOSITE COATINGS
In this study, the co-electrodeposition (CED) method was utilized to produce copper metal matrix composite coatings (Cu-MMC) using lab-made sulfate electrolyte and lab-made synthesized nanoparticles of ferrite-aluminum layered double oxide (Fe/Al LDO) as reinforcement. Copper coatings and co-electrodeposited Cu-MMC coatings with Fe/Al LDO nanoparti...

COPPER MATRIX COMPOSITE LAYERS CO-ELECTRODEPOSITED FROM SULFATE BATH WITH ALUMINA NANOPARTICLES SYNTHETIZED BY SOL-GEL TECHNIQUE
The alumina nanoparticles (Al₂O₃) were synthesized using the sol-gel technique from an inorganic solution. The obtained nanoparticles had a microstructure of corundum after calcination at 1000°C. For characterization of alumina nanoparticles, use the FE-SEM/EDS method with mapping software, XRD, and TEM. The α-Al₂O₃ phase was detected wit...

ANALYSIS OF ELEMENTS IN DANDELION ROOTS SAMPLES COLLECTED FROM THE TERRITORY OF WESTERN SERBIA
The World Health Organization (WHO) estimates that around 70–80% of the world’s population relies on non-conventional medications, most of which are derived from plant-based medicines. Dandelion (Taraxacum officinale) is a widely used medicinal plant in traditional medicine. In recent years, numerous studies have been conducted to impro...

SOIL THERMAL PROPERTIES DETECTION USING INVERSE HEAT TRANSFER ANALYSIS
In this work, the inverse heat transfer analysis (IHTA) utilizing the Finite Element Method (FEM) has been used to detect the thermal properties of the soil where in situ soil temperature (ST) measurements together with that obtained theoretically are used in the solution. The initial values of the unknowns such as the soil thermal diffusivity are ...
