Electrospinning nanofiber membranes (ENMs) have been studied extensively as high-
efficient air filters, but still subject to low filtration efficiency for submicron PMs and limited …

Face masks are widely used for protecting against the COVID-19 pandemic and other
diseases. However, the lack of virucidal properties in conventional face masks increases the …

The efficient filtering of particulate matter (PM) with particle diameters of less than 0.3 μm
(PM0. 3) is challenging. Therefore, mask filter materials with effective interception of PM0. 3 …

van der Waals forces, which are attractive interactions between electroneutral particles and
fibers, are not as widely recognized as other collection mechanisms in fibrous filters. We …

This study investigates the penetration of coronavirus (COVID-19) and oxygen (O 2) in
different commercial face coverings like surgical and N-95 masks using a molecular …

Since the end of 2019, the Corona Virus Disease 2019 (COVID-19) pandemic has led to a
surge in the use of all kinds of medical supplies, especially surgical masks. Based on the …

The world is facing numerous challenges related to providing a high quality of life, in a
sustainable way, to a growing population. These include a clean environment, food security …

In many countries and regions, air pollution has become an environmental problem that
cannot be ignored. Therefore, air filters with high efficiency, low resistance and strong …

Filter media composed of electrostatically charged nonwovens is the key device in an air
purifier. Pleated filters are constructed from a cardboard frame with lattice faces containing a …

Face masks serve to protect the respiratory system from unwanted aerosol droplets, in which
various types of pathogens or pollutants are present. They are particularly important during a …
