Summary: Asphalt releases harmful VOC when heated. Porous materials like zeolite are promoted as they can reduce asphalt VOC through physical and chemical adsorption. This study compares the VOC emissions from zeolite-modified asphalt with different structural characteristics to explore their influence on VOC reduction. Results show that Si/Al ratio affects the types of VOC released. Particle size has a greater impact on VOC emissions than Si/Al ratio, with larger particles having a better reduction effect. Nano polycrystalline zeolite has a stronger VOC reduction effect than single crystal zeolite. Overall, nano-polycrystalline zeolite with large particle size is a better choice for reducing benzene series VOC.

Summary: Studies have shown a balance between oxygen vacancy formation and migration in designing SrCoO3-delta-based materials, using radius and electronegativity as descriptors. Doped SrCoO3-delta materials exhibit promising activity, with Sc-Ta co-doped and Sc-Nb co-doped SrCoO3-delta identified as the best among 91 bimetal-doped perovskites. The results open up a new pathway for designing SOFC cathodes with optimal performance.

Summary: Superhydrophobic surfaces with low adhesion and high antiwetting have attracted significant attention for their unique physical characteristics and potential applications. However, designing robust superhydrophobic surfaces with these properties remains a challenge. In this paper, we discuss the important parameters for characterizing the adhesion and antiwetting properties of superhydrophobic surfaces, and highlight the contradiction between low adhesion and high antiwetting. We also review recent progress in the optimal design of superhydrophobic surfaces using chemical modification and physical microstructure design. Additionally, the application of superhydrophobic surfaces for drag reduction is discussed.

Summary: Adequate, secure, and sustainable water supply gained utmost importance during the COVID-19 pandemic. This research investigates the impact of protective measures on water consumption and post meter leakages in public places. The study found that total flow rates decreased by 42% in public places due to lockdown measures, but excessive post meter leakages were also observed. Controlling leakages and selecting suitable meter sizes are crucial for efficient urban water use.

Summary: Urban drainage networks (UDNs) are important infrastructures for protecting community health and safety. In recent years, complex network theory (CNT) has been used to analyze urban systems. This study evaluates the potential of CNT approaches for assessing the vulnerability of UDNs and planning monitoring systems. The results suggest that tailored metrics based on CNT can effectively analyze vulnerability/resilience, monitoring design, and contaminant/pathogenic spread in UDNs.

Summary: This paper proposes two different approaches for the identification of a monitoring system in sewer networks. The first approach uses a mathematical model and optimization procedure to identify the best monitoring points based on the hydraulic behavior of the system. The second approach utilizes complex network theory tools and evaluates the relevance-based harmonic centrality metric for each node to determine suitable sensor locations. The results indicate that both approaches provide similar solutions in terms of sensor location.
