COVID-19 virus transmission is mainly thorough
aerosols, which are tiny particles of water or other matter that can remain suspended in air for long periods of time and are small enough to penetrate the respiratory system.
A study led by engineers at UC Riverside and The George Washington University, comparing the effectiveness of surgical and cotton masks, a neck gaiter, and nanofiber membranes in removing coronavirus aerosols discovers that nanofiber filter removes almost all of the coronavirus aerosols published in the journal
Environmental Science & Technology Letters. Our work is the first study to use coronavirus aerosols for evaluating filtration efficiency of face masks and air filters, said corresponding author Yun Shen, a UC Riverside assistant professor of chemical and environmental engineering.

Konstantinos Kostarelos, PhD.
Konstantinos Kostarelos, PhD, associate professor at the Cullen College of Engineering at the University of Houston, talks to senior digital content editor Rachel Muenz about his team’s recently-published research focusing on per- and polyfluoroalkyl substances (PFAS) in firefighting foam and why these chemicals are difficult to remediate from the environment.
Q: Why is research into PFAS chemicals so important?
A: First, we should note that there are several compounds in the group of chemicals known as PFAS that have been shown to cause adverse health effects. According to the US Environmental Protection Agency, PFOA [perfluorooctanoic acid] and PFOS [perfluorooctanesulfonic acid] can cause reproductive and developmental, liver and kidney, and
