Abstract: This study systematically investigates the effects of the Mg/P ratio, water-to-binder ratio, pre-curing time, and mineral admixtures on the performance of magnesium potassium phosphate cement (MKPC) as a carbon sequestration material. The results demonstrate that an Mg/P ratio of 3:1 provides the highest compressive strength under both ambient and carbonation curing conditions, with unreacted MgO serving as an additional magnesium source during carbonation. A water-to-binder ratio of 0.25 promotes sufficient hydration and a stable pore structure, leading to enhanced mechanical properties. The incorporation of carbide slag (CCR) notably improved the carbonation rate compared to the control group, while metakaolin contributed to the formation of binding phases that refined the microstructure. Pre-curing duration significantly influenced the reaction kinetics and diffusion of CO₂, with both insufficient and excessive durations negatively affecting carbonation efficiency. The findings provide important insights into the design of high-performance MKPC-based materials for carbon capture and storage. Read More

Abstract: This study aims to comprehensively analyze the application prospects and challenges of nanomaterials in environmental protection, providing theoretical support and practical guidance for the development of eco-friendly technologies. Through systematic review of domestic and international literature, this research systematically examines existing research achievements in environmental applications of nanomaterials while analyzing their unique properties. The findings indicate that nanomaterials have achieved notable successes in water, air, and soil pollution control, demonstrating broad application potential such as innovative pollutant monitoring technologies and multifunctional eco-materials. However, implementation faces multiple challenges including cost control in production processes, technical barriers in large-scale manufacturing, ecological toxicity and biodiversity impacts, as well as regulatory gaps and incomplete policies. To address these issues, the study proposes strategies encompassing low-cost production technology development, overcoming mass production challenges, establishing environmental risk assessment systems, enhancing ecological monitoring and research, promoting policy formulation, and improving regulatory frameworks which all aimed at advancing sustainable application of nanomaterials in environmental protection.

Abstract: This study developed a composite cementitious material using molybdenum tailings, desulfurization gypsum, and carbide slag as the primary raw materials. The appropriate dosage range of each component was first determined through single-factor experiments. The mix proportion was then optimized using an orthogonal experimental design, and a strength prediction model was established via response surface methodology. The microstructure and hydration mechanism were further investigated by XRD and SEM. The results indicate that the optimal mix ratio is molybdenum tailings: desulfurization gypsum: carbide slag = 29.66 g: 35.45 g: 45 g, with a water-to-binder ratio of 0.402. The 28-day compressive strength of the prepared cementitious material reached 5.59 MPa. The main hydration products were ettringite (AFt) and C-S-H gel, which interweave to form a dense microstructure. This system demonstrates a high-value approach to recycling solid waste and offers a sustainable strategy for producing eco-friendly cementitious materials. Read More

Abstract: Dental restoration for tooth defects is a crucial part of oral clinical practice, and the selection of restorative materials directly affects the long-term success rate of restorations. This article systematically compares the mechanical properties, biocompatibility, aesthetic effects, and operability of currently commonly used dental restorative materials (including composite resins, glass ionomer cements, ceramic inlays, metal alloys, etc.). Based on evidence-based medical evidence, clinical selection strategies for different types of defects, tooth positions, and patient needs are proposed, providing scientific decision-making basis for oral physicians.

Abstract: The advent of digital dentistry has revolutionized traditional workflows, with intraoral scanning (IOS) emerging as a cornerstone for direct digital impression acquisition. However, conventional impression materials remain indispensable, particularly for specific clinical scenarios. This review analyzes the properties and application status of novel impression materials developed for and alongside digital technologies. It focuses on the evolution of polyvinyl siloxane (PVS) and polyether (PE) materials, the emergence of hybrid and modified materials, and the growing role of scannable silicones and 3D printing resins. The article evaluates their key performance characteristics—such as dimensional accuracy, stability, hydrophilicity, and compatibility with digital workflows—and discusses their clinical applications in fixed prosthodontics, removable prosthodontics, and implant dentistry. Finally, the challenges and future trends, including the integration of bi-functional materials and additive manufacturing, are explored. Read More

Abstract: Against the contemporary backdrop of converging digital and experience economies, the value realization pathways for traditional cultural IP are undergoing profound transformations. As cultural IPs with significant international influence, Foshan's "Kung Fu" and "Lion Dance" possess a solid foundation for integrated development in culture, commerce, and tourism. However, they still face practical bottlenecks such as solidified consumption scenes, superficial experience models, and lagging digital applications, which constrain the deep release of their value potential. This paper, using scene theory and digital empowerment theory as its core analytical framework, systematically explores two core implementation paths to drive the value chain leap of Foshan's "Kung Fu" and "Lion Dance" IP. The study argues that the key to breaking through the current predicament lies in implementing a dual-drive strategy of "scene remodeling" and "digital empowerment." The scene remodeling path advocates for transcending traditional "tourist spot" thinking by transforming static cultural landmarks into dynamic, deeply engaging "experience fields" through the narrativization, immersion, and lifestyle integration of physical spaces, thereby activating and enhancing existing resources. The digital empowerment path emphasizes leveraging cutting-edge technologies like virtual reality (VR), augmented reality (AR), and big data to break through physical time-space constraints, creating entirely new virtual consumption scenes and interactive experience models to unlock incremental value. To ensure the effective implementation of this dual-drive strategy, it must be supported by a cross-disciplinary industrial ecosystem, a training system for composite talent, an IP protection mechanism for the digital age, and targeted policy guidance. This research aims to provide a theoretically profound and practically operable set of pathway solutions and strategic references for the deep integrated … Read More

Abstract: The paper conducts an experimental study on ultrasonic vibration-assisted milling (UVAM), aiming at addressing issues such as high cutting forces and poor machining quality in traditional milling of silicon carbide particle-reinforced aluminum matrix composites (SiCp/Al). By comparing conditions with and without ultrasonic vibration, the effects of different spindle speeds and feed rates on cutting forces are analyzed. The results show that ultrasonic vibration-assisted machining significantly reduces cutting forces, with a maximum reduction of 34.4%. Cutting forces increase with higher feed rates, but the growth rate slows in the high-speed region. As the spindle speed increases, cutting forces decrease. Cutting forces continue to decrease gradually under ultrasonic conditions, whereas they slightly rebound under non-ultrasonic conditions in the high-speed region. These findings indicate that UVAM can improve the machinability of SiCp/Al composites. Read More
