The incorporation of bioactive compounds into food products represents a promising approach to enhance their functional and health-promoting properties. However, many bioactive compounds, such as polyphenols, essential oils, carotenoids, and omega-3 fatty acids, are highly sensitive to environmental factors, including temperature, oxygen, and light, which limits their direct application in the food industry. Microencapsulation has emerged as an innovative strategy to overcome these challenges by protecting bioactive compounds, improving their stability, controlling their release, and masking undesirable flavors or odors. This article reviews recent advances in microencapsulation techniques, including spray-drying, freeze-drying, coacervation, and innovative methods such as nanoencapsulation and electrospinning. Particular attention is given to the influence of encapsulated bioactive compounds on the physicochemical characteristics, texture, color, and sensory attributes of various food matrices. Furthermore, the paper highlights industrial perspectives, emphasizing the scalability of these techniques, regulatory considerations, and their role in the development of clean-label, functional, and sustainable food products. The findings underline the potential of microencapsulation as a key technology for the next generation of functional foods, bridging consumer expectations with industrial feasibility. Full article

A smart city can be defined as an urban ecosystem that combines new technologies related to digitalization in infrastructure, governance models, and everyday life, as well as inclusivity and stakeholder participation for achieving effectiveness and long-term sustainability. Although many frameworks and co-creative governance approaches emphasize the importance of integrating diverse perspectives in urban innovation, the practical implementation of stakeholder engagement remains a significant challenge in the development of digital strategies. This persistent difficulty often stems from factors such as varying levels of digital literacy, power asymmetries among stakeholders, and insufficient mechanisms for meaningful participation. As a result, there is a risk that smart city initiatives may fall short of their potential to deliver inclusive and sustainable outcomes, ultimately undermining both the legitimacy and the long-term effectiveness of urban digital transformation processes. This is especially relevant in the Italian context. Indeed, despite the relevant number of papers dedicated to stakeholder engagement in smart cities, few studies have explored how municipalities implement these innovative strategies, and even fewer have within the Italian context. This research aims to fill this gap by analyzing the stakeholder engagement in Rome’s smart city strategy and the effectiveness of participatory and co-creative approaches in transforming a city into an effective smart city. The research results reveal that the experience of the Rome Smart City Lab (RSCL) creates a model of participatory governance where the stakeholders can co-create the digital innovation strategies of a municipality and where the stakeholder techniques are fully implemented. The research results provide interesting results useful for both academics and policymakers involved in the digital transformation of a smart city, since the RSCL’s approach confirms that digitalization initiatives become more effective and efficient when they are shaped by the very individuals and groups responsible for their implementation. This participatory process seems to enhance the adaptability and sustainability of digital strategies over time, ultimately contributing to the realization of truly inclusive smart cities.

This article focuses on developing and characterizing one-part rock-based geopolymer slurries using Brazilian rock precursors for well construction and plugging and abandonment (P&A) applications. The study presents the fluid-state and solid-state properties of these geopolymers, as well as X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM), to understand the microstructure of the precursors and the reaction level. The effect of temperature and pressure on the development of compressive strength was investigated. By altering these parameters, the study aimed to examine the impact of various conditions on the strength development of the geopolymer material. Technological tests were conducted following API RP 10B-2. Compressive strength tests were conducted to determine early strength development and thickening time. Post-curing Rietveld refinement by XRD was performed to examine the microstructure and reactivity. Finally, fluid-state properties were also assessed, including thickening time and viscosity. The strength development of geopolymers is observed to be time- and temperature-dependent, as shown by UCS results. The final product has a dense structure, and its long-term performance will require evaluation to determine its sealing capability and volume change as a barrier material. The results highlight the novelty of employing locally available Brazilian rock precursors in one-part geopolymer formulations and provide a scientific basis for their potential application as sustainable alternatives to conventional cements in well construction and abandonment.

Urinary tract infections (UTIs) constitute a severe global health problem, placing a significant burden on healthcare systems worldwide. These infections often lead to frequent hospitalizations, sick leaves, and serious post-infectious complications. One of the most critical aspects of UTI treatment is rapid and accurate identification of pathogens, which increasingly develop resistance to commonly used antibiotics, as well as to newer ones, despite the expectation of sustained efficacy. This alarming trend signals the widespread presence of strains equipped with multiple resistance factors. In this review, attention has been drawn to the current classification of UTIs based on age, gender, risk factors, and preferred treatment strategies. Additionally, this article reviews diagnostic solutions used in this matter, starting from those applied in routine diagnostics and ending with the latest, cutting-edge approaches that are gradually coming into use. Each method varies in its specificity, sensitivity, and costs of implementation, and therefore, the limitations associated with adopting these technologies in widespread UTI diagnostics are also discussed. The review emphasizes the need for further research to optimize these innovations and integrate them into broad clinical practice, ultimately enabling more effective combat against UTIs and limiting the spread of bacterial resistance.

As the development of “smart villages” and “sustainable rural tourism” increasingly becomes a focal point on the global policy agenda, tourism-oriented villages are experiencing a growing demand for digital infrastructure transformation. Against this backdrop, smart outdoor furniture emerges as a noteworthy intervention. However, existing designs for smart outdoor furniture predominantly originate from urban contexts, often failing to align with the distinct preferences, behavioural patterns, and cultural identity of rural users. This study employs a mixed-methods approach, combining Q-methodology with an extended Technology Acceptance Model (TAM), to explore rural users’ technology acceptance pathways. Through Q-sorting, four typical attitude structures were identified: Pragmatic Function-Oriented, Cultural Concern-Oriented, Smart Enhancement-Oriented, and Technology Anxiety-Oriented. These qualitative insights were integrated into an extended TAM framework and validated through a structured survey (n = 319) using Partial Least Squares Structural Equation modelling (PLS-SEM). Findings confirm that Perceived Usefulness and Perceived Ease of Use remain the strongest predictors of user attitude and behavioural intention. Among contextual factors, Function Configuration exerts significant positive influence on both PU and PEOU; Cultural Adaptation significantly enhances PU; Social Influence primarily affects PEOU; Smart Features moderately influence both dimensions; and Perceived Cost Structure affects only PU. This research extends the applicability of the TAM model within rural socio-technical contexts. It provides empirical reference for inclusive and sustainable digital infrastructure design in tourism-oriented villages, while offering practical insights and dissemination pathways for smart design strategies in public spaces within similar socio-cultural environments.

The extraction of lithium and potassium from salt lakes has led to the generation of substantial amounts of magnesium-rich waste streams. These by-products, with their high magnesium content, have contributed to severe environmental degradation in salt lake regions. Therefore, recovering and utilizing magnesium from salt lake resources is a crucial challenge for achieving sustainable development. In this study, magnesium and lithium were separated from evaporated brine—obtained via solar pond technology—using membrane electrolysis. Magnesium was converted into Mg(OH)₂ as a flame retardant, while lithium was refined into battery-grade Li₂CO₃. The final products exhibited high purity, exceeding 99.5% for Mg(OH)₂ and 99.99% for Li₂CO₃. This work systematically investigated the influence of electrolysis temperature on the physicochemical properties of Mg(OH)₂ extracted via membrane electrolysis. The variation in electrolyte temperature was also analyzed in relation to other process parameters, such as electrolyte concentration, current density, and processing time. Results demonstrated that the electrolysis process could maintain a favorable operating temperature through self-heating, even under ambient conditions. Using this electrolysis approach for magnesium–lithium separation from brine, extraction rates of 95.86% for magnesium and 67.46% for lithium were achieved. Full article

It is estimated that around 1.3 billion people, roughly 16% of the global population, live with some form of disability, which can be physical, auditory, visual, intellectual, or psychosocial (mental). To help this group overcome daily functional limitations and improve their ability to perform activities independently, Assistive Technologies (AT) are used. However, understanding the complex effects of these technologies on users’ lives poses challenges in measurement. This research aims to identify and systematise the impacts caused by AT within society, analysing the relationships among these impacts to offer a comprehensive understanding of their scope. A Systematic Literature Review (SLR) was carried out following the PRISMA protocol, supplemented by association rule analysis using the Apriori algorithm with Weka software. Metrics such as Support, Confidence, and Lift were used to evaluate the associations identified by the algorithm. This analysis revealed fourteen distinct types of impacts, categorised into three groups: User Quality of Life, Social and Psychosocial, and Work Environment and Productivity. The findings demonstrated consistent associations, including Autonomy → Independence, Socioeconomic Status → Social Impact, and Education → Social Impact, indicating interconnected effects of assistive devices across functional, educational, emotional, social, economic, and productivity areas. This study supports the Sustainable Development Goals by promoting the development of AT standardisation tools, guiding more inclusive public policies, and encouraging collaborative networks among stakeholders involved in AT research and development.

Digital finance, representing the deep integration of finance and technology, has become a critical enabler of sustainable industrial transformation. Focusing on resource-based enterprises (RBEs)—key actors in transitioning towards sustainable practices—this study investigates how digital finance development fosters new quality productive forces (NQPFs), a core driver of high-quality, sustainable development. Utilizing panel data from Chinese A-share listed RBEs (2008–2022), we measure NQPF using the entropy method and gauge regional digital finance development with the Peking University Digital Financial Inclusion Index (DFII). Empirical analysis employing two-way fixed effects and panel threshold regression models provides robust evidence that digital finance significantly enhances NQPFs within RBEs. Crucially, mechanism analysis identifies three fundamental pathways underpinning sustainability: (1) mitigating financial constraints; (2) facilitating technological innovation and transformation; (3) strengthening green transition awareness. Furthermore, the impact of digital finance exhibits synergistic enhancement alongside increasing environmental regulation intensity and improved financial resource allocation efficiency. Heterogeneity analysis reveals that the effect is more pronounced in regions with lower marketization, within state-owned enterprises, and among RBEs in recession stages. Collectively, these findings offer significant implications for policymakers and industry practitioners aiming to strategically leverage digital finance to accelerate the sustainable transformation of resource-intensive industries, thereby contributing directly to environmentally sustainable and resilient economic development.

With advantages in efficiency and sustainability, assembly splicing technology promotes construction industry upgrading. However, research on the seismic response of assembly splicing subway stations (ASS) is particularly scarce. This work studies the asymmetric ASS in soft soil, establishing a refined finite element model with soil–structure interactions. Three seismic records with different frequency characteristics are applied for nonlinear incremental dynamic analysis. Based on the seismic records that produce the most unfavorable seismic response, this research is conducted on the damage distribution characteristics and the mechanical responses. In addition, the influence of the splicing response at different locations on the interlayer displacement and internal forces of structures is systematically studied. The results indicate that when seismic records with low-frequency characteristics are inputted, the ASS structure in soft soil develops into the most unfavorable state. Under strong seismic action, the top joint of the sidewall exhibits significant horizontal sliding and opening, making key areas of weak seismic performance. It also indicates that the interface contact between precast and cast-in-place components is the primary factor that is causing internal force redistribution. This study provides a reference for performance-based seismic design of ASS in soft soil. Full article
