Rensselaer Polytechnic Institute researchers have developed an accessible way to make N95 face masks not only effective barriers to germs, but on-contact germ killers. The antiviral, antibacterial masks can potentially be worn longer, causing less plastic waste as the masks do not need to be replaced as frequently.
In Physics of Fluids, researchers use principal component analysis along with fluid dynamics simulation models to show the crucial importance of proper fit for all types of masks and how face shape influences the most ideal fit. They modeled a moderate cough jet from a mouth of an adult male wearing a cloth mask over the nose and mouth with elastic bands wrapped around the ears and calculated the maximum volume flow rates through the front of mask and peripheral gaps at different material porosity levels.
In a study that used inorganic, physical and analytical chemistry to mimic respiratory droplets that can carry viruses, researchers demonstrated a mechanism that enables multiple mask materials to be protective. Led by Stony Brook University, the study findings are published in The paper is published in the journal Applied Materials & Interfaces.
Innovations to improve mask efficacy, with increasing focus on nanofiber manufacturing, have resulted in higher filtration efficiency, greater comfort, and easier breathing capacity. However, the effects of microwater droplets on the integrity of nanofibers are relatively unclear. In Physics of Fluids, researchers examine these ambiguities through a visualization of nanofibers interacting with water aerosol exposure. They used high-speed microscopic videos to systematically visualize the evolution of nanofibers with different contact angles, diameters, and mesh sizes under water aerosol exposure.
Dr. Matthew Kampert of Cleveland Clinic Sports Medicine and colleagues published findings today in JAMA Network Open that suggests there’s no harm in masking-up during exercise for most people. They studied twenty healthy people with an average age of thirty-seven.…
For nearly a year, we relied on masks to help prevent the spread of COVID-19. Now, many are removing the facial coverings, but that doesn’t mean it will be easy to shed the anxiety that accompanies a global pandemic. If you’re having difficulty coping with this added stress, psychology experts at the University of Kentucky say you’re not alone.
Research published by JAMA Network Open shows how non-pharmaceutical interventions (NPIs) like mask wearing and physical distancing can help prevent spikes in COVID-19 cases as populations continue to get vaccinated.
A team of researchers has shown that three-layered surgical masks are more effective than single or double-layered masks at stopping large droplets from a cough or sneeze from penetrating through the mask.
Many more health systems are joining the national #MaskUp campaign encouraging Americans to stop the spread of COVID-19 by following safety guidelines. Over just a few days, another 19 health systems with hundreds of hospitals united with 100 health systems nationwide with hospitals numbering in the thousands.
The public service campaign is critical to the health and well-being of all Americans. It is a plea from healthcare professionals everywhere: wear a mask and follow other precautions to save lives and help get our country back on its feet.
Roswell Park Comprehensive Cancer Center is among 100 of the nation’s top health care systems, representing thousands of hospitals in communities across the U.S., that have come together with an urgent plea for all Americans: mask up, because wearing a face mask is our best chance at slowing the surging COVID-19 pandemic now.

It seems there will never be enough “thank-yous” for the incredible doctors, nurses, technicians and support staff members who are working around the clock to help patients who have COVID-19, the dangerous coronavirus disease. Their dedication, determination and spirit enable Johns Hopkins to deliver the promise of medicine.
As the mother of a 2-year-old, with responsibilities that sometimes require escorting COVID-19 patients at Sibley Memorial Hospital, Safety and Security Officer, SPO, Lolita Moore says she takes the necessary steps to protect herself and her family against the virus and prays daily. “I like that I can still be out helping people during the pandemic,” she says.
As communities settle into a new normal, it is clear that masks are the COVID-19 pandemic’s must-have accessory. Keck Medicine of USC experts share advice on how the public can properly wear masks in their daily routines – and cope…

Faculty members at Texas Tech University and the Texas Tech University Health Sciences Center are examining both intermediate materials and finished masks from a multidisciplinary approach.
A small cluster physicist explains why DIY masks work and why even a bandana is better than nothing to fight the spread of COVID19.
The mask extenders created by the Innovation Hub staff reduce the pressure behind the ears, affording the user an increased measure of comfort.
Dr. Russel Buhr, a pulmonologist at UCLA Health, can advise on what’s important to know about mask protection in the light of the Coronavirus outbreak. Not all masks provide equal protection and it’s important to understand how different masks work…
