Recent papers in ACS Environmental Au

ACS Environmental Au is a member of the ACS Au family of journals. These publications are open access, and each one focuses on a specific field relevant to chemistry. Here, we take a look at a few recent papers from ACS Environmental Au, which publishes experimental research and theoretical results in all aspects of environmental science and technology, both pure and applied. The journal welcomes papers on such topics as alternative energy, contaminants in aquatic and terrestrial environments, and green chemistry.

“Revisiting the Key Driving Processes of the Decadal Trend of Aerosol Acidity in the U.S.”
ACS Environmental Au
May 6, 2022

Aerosol acidity is thought to increase with increasing acidic emissions and decrease with more alkaline ones. But that hasn’t been the case in the southeastern U.S. Although alkaline emissions are three times higher than the acidic emissions, the aerosols are functioning as a buffered system that resists pH changes. The authors use multiphase buffer theory to explain these observations.

“Association of Chemical Aggregates and Fungal Moieties Affecting Native Environmental Films”
ACS Environmental Au
April 14, 2022

Although they might start out clean, outside surfaces eventually accumulate “environmental films” that can interact with substances in the air. Microbes can grow in these films, but it’s been unclear what impact they have. These authors found that microbes have short- and long-term chemical effects and can significantly alter environmental films.

“Electrospun Nanofibrous Membranes for Controlling Airborne Viruses: Present Status, Standardization of Aerosol Filtration Tests, and Future Development”
ACS Environmental Au
March 11, 2022

Face masks and air filters made by electrospinning have a very small pore size, a large specific surface area and porosity, and surface charges that are retained on the material. But current studies vary greatly as to how they gauge performance. In this perspective, the authors review the state of the art and then propose a standardized aerosol filtration test protocol.
