The protection provided by facemasks has been extensively investigated since the
beginning of the SARS‐CoV‐2 outbreak, focusing mostly on the filtration efficiency of filter …

Given the difficulty of experimental measurement of respiratory airflow and dispersion
through a face mask, accurate numerical simulation is an important method to increase the …

ABSTRACT A reduced-order model of face mask aerodynamics and aerosol filtration is
introduced. This model incorporates existing empirical data on filtration efficiency for …

There is growing evidence of the high transmission potential of COVID-19 through virus-
laden aerosols. Because aerosols are inhaled in various concentrations, an overall …

The COVID-19 pandemic has affected not only public health but also people's daily lives.
Among various strategies to prevent infection, mask wearing and vaccination are considered …

Elevated face temperature due to mask wearing can cause discomfort and skin irritation,
making mask mandates challenging. When thermal discomfort becomes intolerable …

Surgical and community face masks are used worldwide to reduce the transmission of
respiratory infections in indoor environments. Performance parameters for these loose-fitting …

Respiratory protective equipment (RPE) filters and blocks exhaled pollutants to prevent their
forward movement, protecting the directly exposed individuals and products. Two …

Open fires produce pollutants that critically harm human health. Differences in emission
characteristics and toxic substances from the burning of different biomasses lead to distinct …

Nose-to-brain (N2B) drug delivery is a new approach to neurological disorder therapy as
medications can bypass the blood-brain barrier and directly enter the brain. However, the …
