The influence of preparation method on the properties of ZnO-MgO composites
No full textMetal-oxide nanoparticles are interesting research topic due to their versatility, stability, and potential to enable greener technologies. Zinc oxide magnesium oxide (ZnO-MgO) composites provide interesting new routes for investigation because of easy tunability of physical and chemical properties. In this research the the influence of preparation method on the properties of resulting ZnO-MgO composite was investigated. Starting from nitrate salts of Zn and Mg, ZnO-MgO compostes with molar ratio Zn:Mg = 1:1 were synthesized by alkaline precipitation method, sol- gel method and hydrothermal preparation method. The materials were calcined at 600 oC for 30 minutes. The obtained composites are charaterized by Diffuse reflectance UV-Vis spectroscopy and electrochemical characterization methodes (cyclic voltammetry, electrochemical impedance spectroscopy, Mott-Schotky analysis). The obtained results were used for determination of flat- band potential and heterogeneous electron transfer rate constant. The resaults indicated the dependence of composite properties on the synthesis procedure.Advanced Ceramics and Application : 13th Serbian Ceramic Society Conference : Program and the Book of Abstracts; September 8-10, 2025; Belgrade
Applications of Digital Twins in Personalized Medicine and Healthcare
No full textThe digital twin (DT) system is a complex virtual structure composed of many interrelated substructures optimized to give a complete picture of how it relates to various medical problems or patients. Due to its tight connection with physical objects and digital reality, DT enters our lives, showing an extraordinary potential for diverse medical applications. Due to this evidence, DT offers exceptional useful information for precise personalized diagnosis and possible therapy in medicine. Besides, the application of machine learning (ML) and DT in bioprinting is probably the future of three-dimensional (3D) bioprinting. Big Data and DT are also essential in articulating our future's vision in tissue engineering. Therefore, the most crucial challenge is the creation of a database that supports the construction DT of human organs with resolution on the cell level, and their metabolic functions. In future, 3D bioprinting should become as more as possible digital and in silico, enabling optimal balance between virtual and physical words, finally leading to the more successful use of bioprinting. For adequate bulk production of tissue culture systems, effective software, and comprehensive mathematical models are necessary instead of traditional experimental investigations. Accordingly, DTs should incorporate the mechanics of biological systems as a softer constituted from various mathematical functions that describe relationships between different tissues and corresponding cell cultures

Poster: Sustainable Valorization of Raspberry Pomace Using Biocompatible Ionic Liquids
No full textRaspberry belongs to a group of highly valued fruits, known as berries, which possesses unique flavor and significant nutritional and health benefits attributed to its rich content of bioactive compounds. Bioactives (polyphenols, flavonoids, anthocyanins, and ellagitannins) could exhibit anti inflammatory, antioxidant, and anti-diabetic properties. However, raspberries have a short shelf life and often are processed into juice, wine, jam, or syrup, resulting in substantial amounts of pomace, primarily composed of seeds and pulp, which are commonly discarded as agricultural waste. This study explores the potential of raspberry pomace as a sustainable source of bioactive compounds through the application of green extraction technique. Ionic liquids (hydrophilic: cholinium acetate, cholinium bitartrate, and cholinium ascorbate; and hydrophobic: cholinium decanoate and cholinium dodecanoate) were synthesized and employed as alternative, non-toxic solvents. Direct solid-phase extraction was conducted with the aid of ultrasonic waves. The total phenolic and anthocyanin content was determined spectrophotometrically, while ellagic acid was quantified using HPLC. The results indicate that ionic liquids provide an effective, eco-friendly approach for the valorization of raspberry pomace, highlighting their potential as alternative solvents in bioactive compound extraction. This study underscores the feasibility of utilizing agricultural by-products to obtain valuable bioactive compounds, contributing to sustainability and waste reduction in the berry processing industry.Poster presented at: II Conference FoodWaStop : CA22134 Sustainable Network for agrofood loss and waste prevention, management, quantification and valorisation; 4-5th March 2025; Córdoba, Spain.Abstract: [https://vinar.vin.bg.ac.rs/handle/123456789/16165

A total distance of 80 km was mapped by car and over 4 km by foot. Variations in dose rates were observed depending on the type of terrain and location. The measured values are within the expected natural background radiation for this area.XXXIII симпозијум ДЗЗСЦГ [Друштва за заштиту од зрачења Србије и Црне Горе] : 1-3. октобар 2025. године
Does the law exists without coercion?
No full textLaw is a very complex phenomenon consisting of various, interwoven aspects, which are not necessarily in harmony. In connection with the above, we distinguish normative aspects of law (legal norms and legal acts), value aspects of law (justice, legal certainty, expediency) and factual aspects of law (actual behavior of citizens and authorities). The stated premises lead us to the conclusion that it is very difficult to define the concept of law. However, if we were to analyze existing definitions (classical, prototypical, and prescriptive), we could find certain common characteristics of the concept of law - institutionality, normativity, and coercion. By examining the above characteristics, in this paper we ask the question of whether Nuclear Law is a law at all, bearing in mind that it lacks one of its constitutive elements - coercion.XXXIII симпозијум ДЗЗСЦГ [Друштва за заштиту од зрачења Србије и Црне Горе] : 1-3. октобар 2025. године
Dual-Mode Diagnostics of Thick-Film Strain Sensors for Structural Health Monitoring Under High-Voltage Surge Stress
No full textThis paper investigates the impact of high-voltage surges on the performance of thick-film strain sensors applied in structural health monitoring (SHM). The sensors, fabricated from bismuth-lead ruthenate resistive films on alumina substrates, were subjected to mechanical strain and controlled surge pulses to replicate real-world electrical stress conditions. Experimental results show that while resistance measurements alone provide limited insight, the combination of resistance and noise analysis reveals underlying degradation mechanisms. These findings highlight the robustness of thick-film strain sensors and support their suitability for SHM applications in electrically demanding environments.MIEL : 34th International Conference on Microelectronics; October 13-16, 2025, Niš, Serbia
