“…Increasing the various pollutions such as CO2, NO2, and SO2 molecules causes climate change and loss of balance in nature, which can cause irreparable damage to the planet [1,2]. To keep global temperature rise to less than 1.5-2 ̊C, which scientists say is necessary for preventing the worst impacts of climate change, we'll need to not only reduce emissions but also remove and store some carbon from the atmosphere [3][4][5]. One of various effective ways to pollution capture is implementing atomic membranes.…”

Since the Industrial Revolution, humans have emitted various pollution such as CO2 molecules into the atmosphere. This thickening blanket of heat-trapping greenhouse gases causes the global warming we experience today. So, various methods introduced for remove O2 pollutions in recent years. In this computational study, we describe the Polyether/Polyamide-Ag membrane behavior for O2 molecules purification from CO2, SO2, and NO2 pollutions by Molecular Dynamics (MD) approach. Technically, various structures in current study simulated by using Embedded Atom Model (EAM) and Universal Force Field (UFF). In the first step of current work, physical stability of atomic compounds reported by temperature and total energy calculations. After this process, purification procedure simulated and physical parameter such as filtration value, Young’s modulus, and ultimate strength calculated for atomic performance of atomic membrane reporting. MD outputs indicated the number of absorbed various pollution molecules can be varied from 72–94% ratio. Also, mechanical calculations predicted the atomic membrane was weakened mechanically after purification process. Our simulation results shown young’s module of the Polyether/Polyamide-Ag membrane decreases from 8.73 GPa to 4.32 GPa by SO2 molecules capture process with this matrix. From these results, we expected our modeled atomic membrane can be used in O2 purification process in actual cases.

“…Because city planners can minimize the windward area density by controlling the plot ratio and building density, urban pollution waste gas is expelled with the wind (Bustamante et al, 2011;Mei et al, 2018). Researchers have concluded that various planning and design strategies, such as the creation of ventilation ducts, can improve urban air quality in highdensity core metropolitan areas (Fensterstock et al, 1971;Affum et al, 2003;Diener and Mudu, 2021). Specifically, it is to reasonable to construct urban air ducts by control building density, spacing, height, and size to improve air quality (Ravindra et al, 2019;Bai et al, 2022).…”

Fine particulate matter (PM2.5) pollution is a key issue affecting the health of urban residents. To explore the impact of urban building form on PM2.5 pollution, this study focused on Wuhan, a Chinese megacity. Based on the urban building data, various building form indices were first calculated in grids to quantitatively present the spatial distribution of urban buildings. The city-scale PM2.5 distribution was obtained with satellite remote sensing and ground air pollution monitoring data. The impact of urban building forms on PM2.5 pollution distribution was then analyzed. The results show that the changes in PM2.5 concentration in Wuhan in the north–south direction have a relatively obvious correlation with the windward area ratio of buildings. The dense north–south buildings can slow the spread of near-surface particulate pollution. This finding demonstrates that the building blocking effect of PM2.5 diffusion in Wuhan is significant. The results of this study can provide a reference for urban planning, architectural design, and air pollution control strategies.

“…Reiquam (1971) treated the optimal allocation of source emission in an airshed to minimize the likelihood of violating air quality standards. More general concepts of air pollution control in the context of urban and economic planning, and management programs were treated by Fensterstock et al (1971), Sporn (1971), Croke et al(1971), Smith et al(1972), Kleiman (1971) and Muller (1973).…”
