COVID-19: air pollution remains low as people stay at home

open access: yesAir quality, atmosphere and health, 2020
Coronavirus diseases 2019 (COVID-19) is transmitted worldwide in over a very short time, as it was originated in late 2019 from Wuhan city, China. To reduce the possible effects due to COVID-19, some sort of lockdown activities have been applied in many ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Disparities in PM2.5 air pollution in the United States

open access: yesScience, 2020
Cleaner skies Particulate air pollution in the contiguous United States has decreased considerably over recent decades, but where exactly has that progress been made? Colmer et al. analyzed 36 years of data and found that the spatial distribution of fine

Omnidirectional Transmissive Acoustic Metasurfaces Based on Goldberg Polyhedra

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces omnidirectional acoustic metasurfaces capable of manipulating wavefronts in multiple arbitrary directions simultaneously. A full‐stack pipeline for design, optimization, and fabrication is presented to construct near‐spherical holograms based on Goldberg polyhedra.

Regional and global contributions of air pollution to risk of death from COVID-19

open access: yesCardiovascular Research, 2020
Aims The risk of mortality from the coronavirus disease that emerged in 2019 (COVID-19) is increased by comorbidity from cardiovascular and pulmonary diseases. Air pollution also causes excess mortality from these conditions. Analysis of the first severe

Air Pollution in Europe

open access: yesChemSusChem, 2018
AbstractIn this short critical perspective, we outline the serious problems caused by air pollution in Europe. Using two types of metrics, level assessment and trend assessment, we quantify the contribution of ammonia, NOx, SOx, non‐methane volatile organic compounds, and particulate matter in terms of years of life lost per capita and explain the ...

Spatiotemporal deep learning model for citywide air pollution interpolation and prediction [PDF]

open access: yesarXiv, 2019
Recently, air pollution is one of the most concerns for big cities. Predicting air quality for any regions and at any time is a critical requirement of urban citizens. However, air pollution prediction for the whole city is a challenging problem.

Exploring the relationship between air pollution and meteorological conditions in China under environmental governance

open access: yesScientific Reports, 2020
Extensive studies have been carried out on the impact of human activities on air pollution, but systematic investigation on the relationship between air pollutant and meteorological conditions is still insufficient, especially in the context of China’s ...
