Coughing downward reduces spread of respiratory droplets: study

With many people heading indoors for the winter months and respiratory droplets acting as a major contributor to COVID-19 spread, the scientific community has renewed interest in the dynamics behind how they spread. Modeling ...

New material could remove respiratory droplets from air

Although plexiglass barriers are seemingly everywhere these days—between grocery store lanes, around restaurant tables and towering above office cubicles—they are an imperfect solution to blocking virus transmission.

Porous materials unfavorable for coronavirus survival

As COVID-19 spreads via respiratory droplets, researchers have become increasingly interested in the drying of droplets on impermeable and porous surfaces. Surfaces that accelerate evaporation can decelerate the spread of ...

Masks block 99.9% of large COVID-linked droplets: study

Face masks reduce the risk of spreading large COVID-linked droplets when speaking or coughing by up to 99.9 percent, according to a lab experiment with mechanical mannequins and human subjects, researchers said Wednesday.

Tracking flight trajectory of evaporating cough droplets

The ongoing COVID-19 pandemic has led many researchers to study airborne droplet transmission in different conditions and environments. The latest studies are starting to incorporate important aspects of fluid physics to ...

How everyday speech could transmit viral droplets

It is well known that an individual infected with the coronavirus can spread it to others through respiratory droplets projected by violent expiratory events like coughing and sneezing.
