Numerical simulations are conducted using the generalized Lagrangian mean (GLM) theory and the convection–diffusion equation, implemented through COMSOL Multiphysics software. Unlike other numerical studies, this paper assesses the impact of oscillation boundary condition on mixing performance. The results demonstrate that oscillating the inlet and sharp-edge boundaries significantly improves localized mixing by inducing dynamic, multidirectional acoustic streaming and intricate vortex patterns. For example, oscillating the sharp-edge and inlet boundaries in the <i>X</i>-direction achieves a mixing index (MI) of 84.93%. In contrast, oscillating the sharp-edge and inlet boundaries in both the <i>X</i>- and <i>Y</i>-directions increases the MI to 97.94% for a two-lobed sharp-edge configuration. The results also reveal that the MI improves with an increase in the number of sharp edges, the applied frequency, and the displacement amplitude. However, it decreases as the background inlet velocity increases.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 2","pages":"1223 - 1240"},"PeriodicalIF":2.2,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hawthorn is valued as a medicinal plant due to its bioactive substances, such as flavonoids, phenolic compounds, and antioxidants. Additionally, it has become increasingly popular for fresh consumption in recent years. The aim of the study was to determine the functional food potential of fresh hawthorn fruits with assessing their phenolic, flavonoid, anthocyanin, and antioxidant capacities. The study material consisted of fresh hawthorn (<i>Crataegus</i> spp.) fruits that reached optimum maturity and naturally grew in the autumn season in Çorum province, Turkey. The fruits were randomly collected from 10 different sources at the same maturity period and divided into two different colors (yellow–Group 1 and orange–Group 2). Phenol compounds, total flavonoid, total antioxidant levels, anthocyanin, and ascorbic acid amounts of hawthorn fruits were determined by the Folin–Ciocalteu method, aluminum chloride method, Rel Assay brand commercial kits, pH differential method, and the spectrophotometric method, respectively. Fresh hawthorn fruits of two different colors at optimum maturity were analyzed. Orange hawthorn (Group 2) exhibited higher phenol and total flavonoid levels compared to yellow hawthorn (Group 1). However, tannin content of Group 2 was lower, but this difference was not statistically significant (<i>P</i> &gt; 0.05). Ascorbic acid concentration was significantly lower in orange hawthorn (Group 2) compared to yellow hawthorn (Group 1) (<i>P</i> &lt; 0.05). Anthocyanin levels were higher in orange hawthorn (Group 2) compared to yellow hawthorn (Group 1) (<i>P</i> &gt; 0.05). Similarly, total antioxidant capacity was higher in orange hawthorn (Group 2) than in yellow hawthorn (Group 1) (<i>P</i> &gt; 0.05). Correlation analysis revealed a significant positive correlation between phenolic content and total antioxidant status (TAS) (r = 0.828**) and between flavonoids and TAS (r = 0.750**). Additionally, there was a significant positive correlation between flavonoids and TAS (r = 0.818**). A significant negative correlation was found between ascorbic acid and anthocyanins (r = − 0.467*). The results indicate that fresh hawthorn fruits of different colors, at the same ripeness stage, contain compounds that can provide significant health benefits.

This innovative approach aims to address the current limitations in solubilizing eugenol for potential applications in various industries. Eugenol is extracted from the leaves and buds of cloves, and formulating it into a nanoemulsion enhances its effectiveness, overcoming limitations in its broad-spectrum antimicrobial potential. A eugenol-loaded nanoemulsion was prepared using Tween 80 and Tween 20 surfactants via the spontaneous emulsification method. The physicochemical characteristics, long-term stability, and antimicrobial activity against a wide range of microorganisms were evaluated. Among the selected nanoemulsion formulations, those with the smallest particle sizes, measuring 95, 101, 81, and 77 nm, were identified. Additionally, all formulations exhibited a surface charge of (− 25.0 ± 1.0 mV). Compared with the solution, the eugenol nanoemulsion formulation demonstrated a reduced release rate, indicating the potential for sustained drug release. The final formulation displayed notably lower MICs (minimum inhibitory concentrations) and MBCs (minimum bactericidal concentrations) in pure oil and showed effective antimicrobial and antifungal activity against various microorganisms. Eugenol encapsulated in nanoemulsions had stronger antimicrobial effects than did either pure eugenol or nanoemulsions without eugenol. The spontaneous formation of nanoemulsions is regarded as a highly cost-effective approach that offers time and material savings, along with the production of stable nanoemulsions. This characteristic renders it particularly suitable for industrial applications necessitating high-volume production. Moreover, the antimicrobial properties associated with nanoemulsions make them appropriate for diverse therapeutic uses, including transdermal drug delivery and food preservation.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 2","pages":"1155 - 1163"},"PeriodicalIF":2.2,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11696-024-03847-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
