Researchers reporting in ACS Nano have developed a dynamic respirator that modulates its pore size in response to changing conditions, such as exercise or air pollution levels, allowing the wearer to breathe easier when the highest levels of filtration are not required.
Chula’s Faculty of Engineering joins hands with PTT to develop a 2 in1 face mask, an innovation that protects against PM2.5 dust particles and COVID-19 virus that can be reused more than 15 times, helps reduce waste, is pollution-free, and will be available for sale soon.
Even though it has been widely known that wearing a face mask will help mitigate the community spread of COVID-19, less is known regarding the specific effectiveness of masks in reducing the viral load in the respiratory tracts of those wearing them. In Physics of Fluids, researchers examined the effect of wearing a three-layer surgical mask on inspiratory airflows and the mask’s effects on the inhalation and deposition of ambient particles in the upper respiratory airways.
Using face masks to help slow the spread of COVID-19 has been widely recommended by health professionals. This has triggered studies of the materials, design, and other issues affecting the way face masks work. In Physics of Fluids, investigators looked at research on face masks and their use and summarized what we know about the way they filter or block the virus. They also summarize design issues that still need to be addressed.
Johns Hopkins Medicine, together with 100 of the nation’s top health care systems, representing thousands of hospitals in communities across the U.S., have come together with an urgent plea for all Americans — mask up, because wearing a face mask is one of the best ways to slow the surging COVID-19 pandemic.
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.
The Federation of State Medical Boards’ Board of Directors released the following statement in response to reports from a number of state medical boards of complaints they are receiving about physicians and physician assistants failing to wear face coverings during patient care.
There is a desperate need for low-cost hardware to deal with COVID-19 all over the world. Today, with the evolution of digital manufacturing technologies such as 3D printers and circuit milling systems, humanity can share designs with others who can…
Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, Georgia Institute of Technology researchers have designed a new mask intended to do just that — and are providing the plans so individuals and manufacturers can make it.
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.
