Summary: This study evaluated the antioxidant capacities of three polyphenolic extracts from the Chilean bee industry and found synergistic, additive, and antagonistic effects between the different extracts. Synergy was observed when combining Quillay and Ulmo honeys, as well as multifloral bee pollen and Quillay honey extracts. Total polyphenol concentration did not necessarily reflect the total antioxidant capacity of the mixtures.

Summary: Hygroscopicity is an important property of wood and affects its dimensional stability. This study investigates the effects of sample size on the hygroscopicity of waterlogged archaeological wood. The results show that the hygroscopicity increases as sample size decreases, but the effect is smaller for waterlogged archaeological wood compared to recent wood.

Summary: This study developed two major classes of oligomers extensively used in nail gel formulations - urethane acrylates and polyester acrylates - using sustainable routes. Sustainable nail gels were formulated based on non-isocyanate acrylic functional polyurethane oligomers (NIPU-ACs) and bio-renewable based polyester oligomers (BR-PS), with optimized formulations meeting performance criteria such as fast-curing, easy removability, high gloss, and high durability, making them attractive alternatives to incumbent products in commercial markets.

Summary: A new generation of antimicrobial film was developed by incorporating ulvan extracted from Ulva intestinalis into gelatin from common carp scale and reducing its water sensitivity with the addition of beeswax. The optimal composition of gelatin, ulvan, and beeswax was investigated to achieve composite films with minimum water solubility, water vapor permeability, and maximum tensile strength, elongation at break point, and antibacterial effect. The addition of beeswax improved the water resistance and mechanical properties of the films without compromising their antibacterial properties.

Summary: 213Bi is a promising candidate for targeted alpha therapy, but finding suitable materials to separate it from its parent 225Ac is an ongoing challenge. This study evaluates sulfonated activated carbon (SNCAs) as alternative sorbents for use in radionuclide generators and finds that SNCAs have high and selective uptake of Bi3+. Different elution solutions can efficiently extract Bi3+ from SNCAs. This research suggests that SNCAs with sufficient oxygen-containing groups are promising sorbents for the separation of 213Bi in an inverse 225Ac/213Bi radionuclide generator.

Summary: Three types of red fruit juice and three plant extracts were used to develop different functional beverages. Organoleptic analysis was used to determine the most acceptable fruit juice blend. The optimum fruit juice blend had high polyphenols, antioxidants, anthocyanin, and vitamin C content. The study also determined the optimum level of extracts and essential oil in the fruit juice blends.

Summary: The study found that the degradation of investigated shells is significantly influenced by powder particle size and heating rate, which affect the release of CO2. Additionally, different types of shells exhibit distinct mechanisms during calcination, leading to varying CO2 concentrations that impact temperature and activation energy.

Summary: This study examines erosion processes and their impacts on forest management in the hilly terrains of the Crveni potok catchment in southeastern Serbia. The study identifies different erosion types and discusses the factors influencing erosion, such as soil density, slope, rainfall, and vegetation characteristics. Various remote sensing and geospatial techniques are used to assess erosion factors, and conversion models are used to estimate soil erosion rates. The study provides valuable insights into prioritizing soil conservation and implementing site-specific remediation measures for sustainable forest management.

Summary: The concentrations of cadmium (Cd), lead (Pb), and nickel (Ni) in regular and slim cigarette brands in the Serbian market were analyzed, and their human health risks were evaluated. The metal concentrations varied between cigarette brands, with higher levels in regular cigarettes but higher concentrations per cigarette tobacco mass in slim cigarettes. Counterfeit cigarettes had slightly higher metal concentrations than authentic brands. Lead was found to be the most abundant toxic metal, followed by nickel and cadmium. The calculated cumulative hazard index (HI) and incremental lifetime cancer risk (ILCR) indicated a low noncarcinogenic risk and a low but not negligible carcinogenic risk from Cd, Pb, and Ni. The probabilistic and deterministic approaches yielded similar results for the mean HI and ILCR values. A Monte Carlo simulation was used to reduce the uncertainty of health risk estimation, and sensitivity analysis showed that cigarette mass was the most influential factor, followed by Cd content.

Summary: Partial cation substitution can change the physical properties of compounds, and in this study, yttrium-substituted iron oxide nanoconstructs (YIONs) were prepared. The Y3+ substitution in maghemite (γ-Fe2O3) crystal structures was limited to 1.5%. The YIONs showed excellent heating efficiency and low toxicity, making them suitable for potential medical and technological applications such as magnetic hyperthermia cancer treatment and catalysis.

Summary: Despite the practical approach for characterizing the environmental risk of potentially toxic elements (PTEs) from steel production, the analysis of bioavailable PTEs concentrations in soil is often overlooked in managing polluted sites. This study investigated the DTPA-extractable forms of PTEs in soils near a major Serbian steel production plant, revealing significant variability and suggesting an anthropogenic origin. Self-organizing maps (SOMs), principal component analysis (PCA), and positive matrix factorization (PMF) further confirmed the common origin and provided a basis for comprehensive assessment and soil remediation.

Summary: The study investigated the utilization of construction and demolition debris in industrial wastewater treatment through the sorption of Co2+ and Ni2+ ions. Although cost-effective and locally available, the sorption characteristics and application of selected waste composites have not been thoroughly investigated. The waste materials were characterized for mineral and surface composition, radioactivity, stability at different pH values, as well as pH and electrical conductivity of the suspension and filtrate. The sorption capacities of the waste materials were determined in batch experimental conditions. The results showed that cement-based materials have a high affinity for Co2+ and Ni2+ ions, effectively reducing their mobility and bioavailability in wastewaters.
