This data-intensive study examined civic engagement in urban environments, and we found a varied participant sample with ages ranging from 22 to 40 (mean age 31.4), nearly equal gender distribution (52% female, 48% male), and a range of educational backgrounds, including postgraduates (35%), high school graduates (25%), and bachelor's degree holders (40%). A rich tapestry of civic activities was found throughout our inquiry, with 15% making financial contributions, 35% attending, and 45% actively volunteering. Social network research revealed that participants with a wider range of social connections had higher levels of engagement, underscoring the critical function that social networks play in promoting civic participation. Informed urban development and community cohesiveness depend on understanding the complex interactions between demographics, participation roles, and social networks, all of which are shaped by this research.

Nanoparticles size can have an impact on a material's physico-chemical properties, such as optical qualities. In materials science, "green" synthesis has gotten a lot of interest as a dependable, sustainable, and environmentally friendly way to make a variety of nanoparticles, such as metal/metal oxide nanoparticles and hybrid materials. In this study, we synthesized a CuO/TiO2 nanocomposite based on Rubus Ellipticus leaves extract and it was used to degrade Methylene blue dye in sunlight presence. Green synthesized CuO/TiO2 nanocomposite was well characterized using SEM, XRD and FTIR methods. These analytical techniques all show that CuO/TiO2 nanocomposite has formed.The XRD patterns clearly indicate the formation of CuO/TiO2 nanocomposite, which is confirmed by the disappearance of characteristic peaks of CuO nanoparticles after mixing with TiO2 nanoparticles. The percentage dye degradation increased with time and the amount of the catalyst used. The maximum dye degradation efficiency of 96% was achieved at 100 min using a 100 mg dosage of the CuO/TiO2 nanocomposite. The nanocomposite can potentially be used in wastewater treatment applications. Future studies should focus on optimizing the synthesis process to increase the economic efficiency of the CuO/TiO2 nanocomposite. [ABSTRACT FROM AUTHOR]
