Penn Engineering materials scientist Shu Yang and Weitzman School of Design architect Masoud Akbarzadeh teamed up to develop a 3D concrete printing system that captures carbon dioxide and boosts the ...

NOx pollution occurs when nitrogen oxides are released as a gas into the atmosphere during the high-temperature combustion of fossil fuels. These nitrogen oxides consist mainly of two molecules ...

By combining a multitask deep learning method and a nitrogen PROSPECT and scattering by arbitrarily inclined leaves (N-PROSAILs) model, we proposed a multitask learning-based hybrid model (ML-HM) for ...

Air quality monitoring and research have been gaining importance in Argentina and Latin America, mainly in megacities where pollution reaches critical levels as in other places of the world. This work ...

High time-resolution monitoring of nitrogen dioxide (NO 2) is of great importance for studying the formation mechanism of aerosols and improving air quality. Based on the Griess–Saltzman (GS) reaction ...

Recent data shows the lowest nitrogen dioxide reading to date in May 2025, at 16.5 micrograms per cubic metre. Cllr Graham Plant, cabinet member for highways, infrastructure and transport at Norfolk ...

Semiclathrate hydrates are water-based crystalline host–guest materials that consist of water and large ionic substances. To expand their unique functions, investigation into asymmetric quaternary ...
