Summary: This study examined the characteristics of aerosol liquid water content (ALWC) in PM2.5 in Delhi using real-time measurements and thermodynamic modeling. The results showed that ALWC increased by 60% in the winter of 2020-2021 compared to the previous year, with an exponential relationship with relative humidity (RH) and significant increase when RH > 80%. Ammonium sulphate and ammonium nitrate were the main contributors to ALWC, with their relative contributions varying under different RH conditions. Increased ALWC due to high PM2.5 and RH resulted in a significant reduction in visibility.

Summary: COVID-19 rebounded in China in January 2021, leading to a lockdown in Harbin, Heilongjiang province. During the lockdown period, coal combustion emissions remained stable while vehicle emissions significantly decreased. The lockdown period also saw an enhancement of secondary aerosol formation and the presence of photochemistry-related reactions not reported in the region before.

Summary: Synergistic additives, ammonium salts, have been used in the chemical vapor deposition (CVD) growth of MoS2 to achieve controlled domain layering and shape, as well as centimeter-scale films. This method enables direct fabrication of MoS2 electronic devices on clean substrates without the need for transfer steps, and it also promotes improved hydrogen evolution reaction (HER) performance. The use of ammonium salts in CVD paves the way for practical applications of MoS2 in modern electronics and catalysis.

Summary: This study presents a sensitivity analysis of an aerosol model for ammonium salt particle formation and explores the effects of different input variables on model outputs. The results show that variations in particle size are influenced by HNO3, H2SO4, and temperature. The degree of ammonia slip is driven by temperature and the ammonia ratio. The removal efficiency of HNO3 is very high and is not significantly influenced by the concentration of H2SO4. The variability of model run time mainly depends on variations in temperature, relative humidity, and the ammonia ratio.

Summary: The study found that the impact of aerosols on diffuse radiation is related to the severity of pollution, with the ratio of diffuse radiation increasing as pollution worsens. Aerosol optical properties are significantly correlated with diffuse radiation and its ratio, and the forward scattering of aerosols and aerosol diffuse radiative effect respond differently to pollution levels.

Summary: There is an urgent requirement to advance ecofriendly antimicrobial polymers for solving the bacterial infections. Polymers with quaternary ammonium/phosphonium salts are considered one of the most promising materials for the antibacterial efficacy. The modified polymers exhibited high antibacterial activity against gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, and Proteus vulgaris) and gram-positive bacteria (Staphylococcus aureus). They also showed moderate to strong cytotoxic effects against MCF-7 and Hela.

Summary: This study investigates the hourly inorganic aerosol chemistry and its impact on atmospheric visibility over an urban area in Central Taiwan. The results show that the interaction between NO3- and ALWC leads to severely impaired visibility. It is also found that reducing NOx and NH3 can improve visibility, but reducing NH3 requires greater efforts.

Summary: The seasonal and diurnal characteristics of the vertical distribution of aerosols in urban Beijing from 2017 to 2021 were studied using long-term Raman-Mie LiDAR observations. The influence of aerosol vertical distribution, meteorological conditions within the boundary layer, optical-radiometric properties of aerosols, and their interconnections were investigated during a heavy haze pollution event in Beijing from 8 to 15 February 2020 using meteorological and sun photometer data. The aerosol extinction coefficient was highest in summer, followed by winter, and roughly equal in spring and autumn. During the haze pollution event, the particulate matter mainly consisted of scattered spherical fine particles, and the accumulation time of pollutants measured via AOD(440nm) and PM2.5 mass concentration was different due to the hygroscopic growth of the aerosol particles. This growth increased scattering and led to an increase in the aerosol optical depth. The vertical transport of particulate matter also contributed to the increase in the aerosol optical depth.

Summary: We propose a regional calibration of low-cost particulate matter (PM) sensors using a multivariate Tobit model with historical weather and air quality data to improve accuracy of ambient air monitoring. Training data from two regions in Korea and one in Singapore were used to build a visibility-based calibration model. Field measurements in Jeju and Singapore showed improvement in R-2 values and reduction in errors after applying the model. Our findings suggest that regional calibration enhances the applicability of low-cost monitors.

Summary: The downward trend of NOX concentrations in Taiwan does not reflect the reduction of nitrate (NO3-). Instead, the proportion of NO3- in PM2.5 has increased in recent years. This study found that the reaction between NO2 and OH during the daytime is a major contributor to HNO3, while the heterogeneous reaction is the main formation mechanism of NO3-. Controlling O-3 may be another useful strategy to reduce NO3-.

Summary: This study evaluates the effectiveness of different emission control standards on evaporative emissions in Europe during a heatwave in July 2019. The results show that Euro6d standards reduce per-vehicle evaporative NMVOC emissions by 25.0% compared to Euro5 standards, and proposed Euro7 controls can provide an additional 35.3% reduction. During heatwave periods, Euro7 controls demonstrate better attenuation of temperature-driven emissions increases compared to Euro6d controls. These findings suggest that adopting more stringent standards and control systems can achieve significant reductions in NMVOC emissions and associated air quality and health impacts.

This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
