Summary: This study investigated the refueling emissions from China 6 vehicles equipped with the onboard refueling vapor recovery (ORVR) system and found that they have significantly higher proportions of small alkanes and alkenes (C2-C3) and lower proportions of C6-C8 hydrocarbons compared to vehicles without emission control measures. The market-share-weighting emission factors (EFs) of total hydrocarbons (THCs) and total VOCs for China 6 vehicles indicate a control efficiency of approximately 98.8% compared to vehicles without emission control. The study also developed a high spatiotemporal resolution refueling emission inventory for a typical Chinese city, showing a significant reduction in refueling emissions with the implementation of the ORVR system.

Summary: Continuous tightening emission standards have led to a reduction in organic gas emissions from gasoline vehicles, with VOC emissions being the most effectively controlled subgroup. Along with more stringent emission standards, the mass fraction of VOCs in TOGs decreased while IVOCs increased. Moreover, the study highlights the importance of controlling OVOC emissions and addressing IVOC emissions from LDGVs for future improvement.

Summary: Competition for adsorption sites between atmospheric moisture and volatile organic compounds can significantly impact the VOC removal performance of metal-organic framework adsorbents like MIL-101. In this study, a vapor phase deposition of polydimethylsiloxane (PDMS) was used to create more hydrophobic MIL-101 composites, resulting in enhanced internal hydrophobicity and intact porosity. The MIL-101-PDMS composite showed superior performance in capturing toluene, exhibiting higher adsorption capacity and overall capture rate compared to pristine MIL-101, and maintaining excellent structural stability and adsorption performance after multiple sorption/desorption cycles.

Summary: Biochar derived from corn stalk doping with activated carbon was used to sorb benzene and o-xylene. The specific surface area, total pore volume, and micropore volume of microwave biochar increased with increasing microwave power, which resulted in higher adsorption capacities for benzene and o-xylene. Benzene adsorption was mainly influenced by surface interaction and partition mechanisms, while o-xylene adsorption was governed by pore filling.

Summary: Tree stems are important sources of volatile organic compounds (VOCs) that play crucial roles in tree defense and atmospheric chemistry. However, the magnitude and environmental drivers of stem VOC emissions in various forest ecosystems are not well understood. Drought can lead to nonlinear decreases in monoterpene and acetaldehyde emissions, but large peaks of emissions can still occur in late summer under dry conditions, possibly due to abiotic or biotic stressors.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
