While the use of face masks in public has been widely recommended by health officials during the current COVID-19 pandemic, there are relatively few specific guidelines pertaining to mask materials and designs. A study in Physics of Fluids looks to better understand which types are best for controlling respiratory droplets that could contain viruses. The team experimented with different choices in material and design to determine how well face masks block droplets as they exit the mouth.Read more
Since March, the COVID-19 pandemic has changed the way we learn, work and socialize. Now, as nearly all of Pennsylvania is in the green phase of reopening, it is essential for people to remain vigilant by wearing face masks when unable to maintain proper social distancing.Read more
Regions with an early interest in face masks had milder COVID-19 epidemics, according to a new letter-to-the-editor published in the American Journal of Respiratory and Critical Care Medicine.Read more
• Cambridge-led modelling looks at population-level facemask use.
• The more people use facemasks in public, the smaller the ‘R’.
• Even basic homemade masks significantly reduce transmission at a population level.
• Researchers call for information campaigns – “my mask protects you, your mask protects me” – that encourage the making and wearing of facemasks.
Scientists and engineers are collaborating to translate existing water filtration technology to create a new fabric that will not only capture viruses, like the coronavirus, but also deactivate them.Read more
A team of FAU nurses is addressing the dire needs of a low income neighborhood in West Palm Beach by spearheading programs to provide lifesaving PPE such as face masks for those in need during the COVID-19 pandemic. People living in poverty as well as homeless individuals and those struggling with social determinants of health are at a higher risk of contracting COVID-19 and dying from it.Read more
Researchers report in ACS Nano that a combination of cotton with natural silk or chiffon can effectively filter out aerosol particles –– if the fit is good.Read more
A preliminary, flow visualization experiment suggests that staying 6 feet apart may not be sufficient. It only took the particles from the simulated cough a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet. For a heavy cough, the particles can even travel up to 12 feet. In addition, a face mask doesn’t stop the particles 100 percent, but it does slow down the cough jets.
In the race to identify solutions to the COVID-19 pandemic, researchers at the Department of Energy’s Oak Ridge National Laboratory are joining the fight by applying expertise in computational science, advanced manufacturing, data science and neutron science.Read more
Engineers at Binghamton University, State University of New York are working with healthcare providers in the region to develop technology to help deal with the coronavirus pandemic.
