Rheumatoid arthritis (RA) is a complex and chronic disease that often causes long-term pain and joint swelling in patients, and even causes joint deformity and dysfunction. The pathogenesis of this disease involves abnormal activity of the immune system, causing immune cells to attack the bodys joint tissues, which triggers an inflammatory response. During these inflammatory processes, the accumulation of reactive oxygen and nitrogen species (RONS) is considered to be one of the key factors that aggravate inflammation and damage joint tissues. To address this problem, we designed a method that takes advantage of the targeting properties of melanin nanoparticles. These nanoparticles have excellent biocompatibility, can remain stable in the body, and can be accurately targeted to the site of inflammation. In addition, these nanoparticles also have strong free radical scavenging ability, which can effectively neutralize excessive RONS, reduce the inflammatory response and weaken joint tissue damage. The promise of this treatment strategy is encouraging and offers new hope for patients with RA. By reducing inflammation, protecting joint tissue, and possibly even reversing the disease process to some extent, this melanin nanoparticle holds great promise.

Since the 20th century, there has been an increasing reliance on groundwater due to the rapid development of agriculture and industry. This has resulted in the exploitation of groundwater in large quantities, leading to global land subsidence problems. Tianjin is one of the cities where this problem first emerged, but few studies and surveys have been conducted. As a result, the lack of management of groundwater extraction has caused the issue of land subsidence to become more prominent in recent years. By investigating and collating global research on land subsidence problems caused by groundwater extraction, it is concluded that mathematical and numerical methods, global information systems, remote sensing, and other technologies can be utilized to monitor and predict groundwater levels. Regional management measures can then be developed based on simulation results. However, the application of such technology in Tianjin is insufficient, and there is a need to strengthen the connection between management measures and research data analysis results.

This paper provides a comprehensive analysis of the recent advancements in electrochemical double-layer capacitors (EDLCs) and pseudocapacitance, emphasizing the pivotal role of carbon-based materials, metal oxides, conducting polymers, and composites in augmenting the energy storage landscape. Through a systematic collection of electrochemical performance metrics, we elucidate the inherent advantages of these materials, such as superior electrical conductivity, enhanced surface area, and chemical robustness, which are instrumental in the development of next-generation supercapacitors. We discuss the integration of novel materials like reduced graphene oxide/hexagonal boron nitride composites, carbon onions, and various metal oxides that contribute to a significant increase in energy density and cycling stability. This work also highlights innovative fabrication techniques and synthesis methodologies that have resulted in electrodes with remarkable performance enhancements. Furthermore, the exploration of synergistic effects between different materials has led to hybrid structures that exhibit improved capacitive properties and operational efficiency.

Burlington VT has been expanding in the last few decades due to new immigrants moving into the area for opportunities. Accurate and comprehensive data on the landscape, vegetation coverage, and human activities are essential for knowing the current status of the city and its surrounding environment and for planning the future city expansion by the government. The current study employed remote sensing as the currently most advanced method to measure and monitor the landscape changes and urban expansion of the Burlington area between 2015 and 2023. The results from the remote sensing clearly showed that the lake shape changed, the wasteland areas decreased and the human activities expanded in the Burlington area between the year 2015 and the current year. These clear trends supported by the satellite images and the potential correlation between these trends provide valuable information for city regulators to decide how the city should be expanded, how the environment should be protected, and what issues need to be addressed in the future.

Plywood is a more affordable material for the residential construction industry due to its lower cost and easy availability. However, earthquakes are the biggest barrier for wood structures to stand for a long time, as the materials can easily deform or collapse when subjected to seismic forces. This paper aims to explore the performance of plywood structures during an active earthquake by conducting a series of tests and simulations. In this study, plywood property was explored in the four-point bending experiment to determine its stress-strain relationship, and the results were used to identify the materials young modulus, a key parameter for designing more resilient structures. In addition, a finite element model of a plywood house structure was developed in the ABAQUS application, and the seismic movements with five different velocity values were applied to determine the stress distribution and deflections of the structure. The results provide insights into the dynamic behavior of plywood structures under different seismic movements.

In recent years, with the increasingly rapid development of the glass curtain wall and its gradually mature use in architecture, many designers choose to use glass curtain walls when designing buildings in order to get the desired building facade effect. As a result, there are many new architectural styles and building facade effects. Against this background, this paper discusses how glass curtain wall is applied in architecture and how it helps and influences architectural design styles and techniques. To conclude, the glass curtain wall has been widely used in the design of high-rise buildings and public buildings at this stage, and it also helps designers to more conveniently adjust the virtual-real relationship of building facades and the overall architectural style. The use of large-area glass curtain walls in the design of facades can achieve special effects that cannot be replaced by other materials. At the same time, the application of glass facades also promotes the process of architectural design modernization.

Studies have shown that the 2022 anomalous climate change is different from previous La Nia phenomena. Using the data of the maximum temperature, minimum temperature and temperature difference from 2020 to March 2021 in Hong Kong, the grey model was used to compare the maximum and minimum temperature values in 2022 with the actual values and found that the values were close. The La Nia phenomenon occurred in March 2022, concluding that La Nia is not a major contributor to climate change in Hong Kong. Climate change in Hong Kong is also linked to typhoons, increased carbon dioxide levels in the air, ocean temperatures and other factors. The study concluded that the main cause of the extreme weather in Hong Kong in 2022 was not the occurrence of La Nia, but a combination of factors such as cumulative carbon dioxide emissions, human activities, the altitude of the Tibetan Plateau, and typhoons.

Lithium-ion secondary batteries (LIBs) are battery systems with high energy densities. They are essential components of todays information-rich, mobile societys portable, entertainment, computing, and telecommunications technology. After 1981, most of the research on anode materials mainly focused on the anode containing Li, such as LiAl alloy, LiC alloy, etc. These materials have high prices, unstable cycling performance, and are difficult to be commercialized. The successful commercialization of LIBs began in 1991 with SONYs manufacturing of petroleum coke-based anode materials. Among them, anode plays a crucial role in LIBs. Anode materials that have been commercialized include carbon, alloys, and lithium titanate. Lithium-ion batteries using carbon anode materials and lithium titanate anode materials can meet the needs of electric vehicles (EVs) and large-scale energy storage applications to a certain extent, and alloy anode materials can promote the energy density of LIBs. The properties of the commercialized anode materials are covered in this paper. Next generation anode materials such as silicon anode materials are also introduced.

Winglets are structures with unique shapes designed on the wingtips of aircraft. They were first time justified as a device that can improve aircraft fuel efficiency by generating more lift in the last century and have been widely used in the aviation industry until today. The current winglets installed on jetliners, however, are fixed, resulting in that winglets can only be aerodynamically optimized for single flight condition. Searching for further improvement on flight performance, this paper investigates and analyzes two types of morphing winglets that can adjust their configurations during flight for aerodynamic optimizations under multiple conditions. Three computational studies based on three current business jets, representing aerodynamic characteristics of typical jetliners, are referenced. The studies results are presented and categorized into different flight phases, and the flight performance is embodied in terms of aircraft maximum climb rate, lift-to-drag ratio, and cruise fuel flow rate. Finally, the overall performance gained and the feasibility of implementation are evaluated.
